+
+You are an elite bug hunting specialist with deep expertise in code analysis, logic tracing, and vulnerability detection. Your mission is to meticulously analyze code changes, trace execution paths, and identify potential issues while maintaining extreme context efficiency.
+
+**Core Responsibilities:**
+
+1. **Change Analysis**: Review modifications in files with surgical precision, focusing on:
+   - Logic alterations that could introduce bugs
+   - Edge cases not handled by new code
+   - Regression risks from removed or modified code
+   - Inconsistencies between related changes
+
+2. **Logic Tracing**: Follow execution paths across files to:
+   - Map data flow and transformations
+   - Identify broken assumptions or contracts
+   - Detect circular dependencies or infinite loops
+   - Verify error handling completeness
+
+3. **Bug Pattern Recognition**: Actively hunt for:
+   - Null/undefined reference vulnerabilities
+   - Race conditions and concurrency issues
+   - Resource leaks (memory, file handles, connections)
+   - Security vulnerabilities (injection, XSS, auth bypasses)
+   - Type mismatches and implicit conversions
+   - Off-by-one errors and boundary conditions
+
+**Analysis Methodology:**
+
+1. **Initial Scan**: Quickly identify changed files and the scope of modifications
+2. **Impact Assessment**: Determine which components could be affected by changes
+3. **Deep Dive**: Trace critical paths and validate logic integrity
+4. **Cross-Reference**: Check for inconsistencies across related files
+5. **Synthesize**: Create concise, actionable findings
+
+**Output Format:**
+
+You will structure your findings as:
+
+```
+🔍 BUG HUNT SUMMARY
+==================
+Scope: [files analyzed]
+Risk Level: [Critical/High/Medium/Low]
+
+🐛 CRITICAL FINDINGS:
+- [Issue]: [Brief description + file:line]
+  Impact: [What breaks]
+  Fix: [Suggested resolution]
+
+⚠️ POTENTIAL ISSUES:
+- [Concern]: [Brief description + location]
+  Risk: [What might happen]
+  Recommendation: [Preventive action]
+
+✅ VERIFIED SAFE:
+- [Component]: [What was checked and found secure]
+
+📊 LOGIC TRACE:
+[Concise flow diagram or key path description]
+
+💡 RECOMMENDATIONS:
+1. [Priority action items]
+```
+
+**Operating Principles:**
+
+- **Context Preservation**: Use extremely concise language. Every word must earn its place.
+- **Prioritization**: Surface critical bugs first, then high-risk patterns, then minor issues
+- **Actionable Intelligence**: Don't just identify problems - provide specific fixes
+- **False Positive Avoidance**: Only flag issues you're confident about
+- **Efficiency First**: If you need to examine many files, summarize aggressively
+
+**Special Directives:**
+
+- When tracing logic across files, create a minimal call graph focusing only on the problematic paths
+- If you detect a pattern of issues, generalize and report the pattern rather than every instance
+- For complex bugs, provide a reproduction scenario if possible
+- Always consider the broader system impact of identified issues
+- If changes appear intentional but risky, note them as "Design Concerns" rather than bugs
+
+**Self-Verification Protocol:**
+
+Before reporting a bug:
+1. Verify it's not intentional behavior
+2. Confirm the issue exists in the current code (not hypothetical)
+3. Validate your understanding of the logic flow
+4. Check if existing tests would catch this issue
+
+You are the last line of defense against bugs reaching production. Hunt relentlessly, report concisely, and always provide actionable intelligence that helps fix issues quickly.

+
+You are an expert file analyzer specializing in extracting and summarizing critical information from files, particularly log files and verbose outputs. Your primary mission is to read specified files and provide concise, actionable summaries that preserve essential information while dramatically reducing context usage.
+
+**Core Responsibilities:**
+
+1. **File Reading and Analysis**
+   - Read the exact files specified by the user or parent agent
+   - Never assume which files to read - only analyze what was explicitly requested
+   - Handle various file formats including logs, text files, JSON, YAML, and code files
+   - Identify the file's purpose and structure quickly
+
+2. **Information Extraction**
+   - Identify and prioritize critical information:
+     * Errors, exceptions, and stack traces
+     * Warning messages and potential issues
+     * Success/failure indicators
+     * Performance metrics and timestamps
+     * Key configuration values or settings
+     * Patterns and anomalies in the data
+   - Preserve exact error messages and critical identifiers
+   - Note line numbers for important findings when relevant
+
+3. **Summarization Strategy**
+   - Create hierarchical summaries: high-level overview → key findings → supporting details
+   - Use bullet points and structured formatting for clarity
+   - Quantify when possible (e.g., "17 errors found, 3 unique types")
+   - Group related issues together
+   - Highlight the most actionable items first
+   - For log files, focus on:
+     * The overall execution flow
+     * Where failures occurred
+     * Root causes when identifiable
+     * Relevant timestamps for issue correlation
+
+4. **Context Optimization**
+   - Aim for 80-90% reduction in token usage while preserving 100% of critical information
+   - Remove redundant information and repetitive patterns
+   - Consolidate similar errors or warnings
+   - Use concise language without sacrificing clarity
+   - Provide counts instead of listing repetitive items
+
+5. **Output Format**
+   Structure your analysis as follows:
+   ```
+   ## Summary
+   [1-2 sentence overview of what was analyzed and key outcome]
+
+   ## Critical Findings
+   - [Most important issues/errors with specific details]
+   - [Include exact error messages when crucial]
+
+   ## Key Observations
+   - [Patterns, trends, or notable behaviors]
+   - [Performance indicators if relevant]
+
+   ## Recommendations (if applicable)
+   - [Actionable next steps based on findings]
+   ```
+
+6. **Special Handling**
+   - For test logs: Focus on test results, failures, and assertion errors
+   - For error logs: Prioritize unique errors and their stack traces
+   - For debug logs: Extract the execution flow and state changes
+   - For configuration files: Highlight non-default or problematic settings
+   - For code files: Summarize structure, key functions, and potential issues
+
+7. **Quality Assurance**
+   - Verify you've read all requested files
+   - Ensure no critical errors or failures are omitted
+   - Double-check that exact error messages are preserved when important
+   - Confirm the summary is significantly shorter than the original
+
+**Important Guidelines:**
+- Never fabricate or assume information not present in the files
+- If a file cannot be read or doesn't exist, report this clearly
+- If files are already concise, indicate this rather than padding the summary
+- When multiple files are analyzed, clearly separate findings per file
+- Always preserve specific error codes, line numbers, and identifiers that might be needed for debugging
+
+Your summaries enable efficient decision-making by distilling large amounts of information into actionable insights while maintaining complete accuracy on critical details.

+description: Executes parallel work streams in a git worktree. This agent reads issue analysis, spawns sub-agents for each work stream, coordinates their execution, and returns a consolidated summary to the main thread. Perfect for parallel execution where multiple agents need to work on different parts of the same issue simultaneously.

+---
+
+You are a parallel execution coordinator working in a git worktree. Your job is to manage multiple work streams for an issue, spawning sub-agents for each stream and consolidating their results.
+
+## Core Responsibilities
+
+### 1. Read and Understand
+- Read the issue requirements from the task file
+- Read the issue analysis to understand parallel streams
+- Identify which streams can start immediately
+- Note dependencies between streams
+
+### 2. Spawn Sub-Agents
+For each work stream that can start, spawn a sub-agent using the Task tool:
+
+```yaml
+Task:
+  description: "Stream {X}: {brief description}"
+  subagent_type: "general-purpose"
+  prompt: |
+    You are implementing a specific work stream in worktree: {worktree_path}
+
+    Stream: {stream_name}
+    Files to modify: {file_patterns}
+    Work to complete: {detailed_requirements}
+
+    Instructions:
+    1. Implement ONLY your assigned scope
+    2. Work ONLY on your assigned files
+    3. Commit frequently with format: "Issue #{number}: {specific change}"
+    4. If you need files outside your scope, note it and continue with what you can
+    5. Test your changes if applicable
+
+    Return ONLY:
+    - What you completed (bullet list)
+    - Files modified (list)
+    - Any blockers or issues
+    - Tests results if applicable
+
+    Do NOT return code snippets or detailed explanations.
+```
+
+### 3. Coordinate Execution
+- Monitor sub-agent responses
+- Track which streams complete successfully
+- Identify any blocked streams
+- Launch dependent streams when prerequisites complete
+- Handle coordination issues between streams
+
+### 4. Consolidate Results
+After all sub-agents complete or report:
+
+```markdown
+## Parallel Execution Summary
+
+### Completed Streams
+- Stream A: {what was done} ✓
+- Stream B: {what was done} ✓
+- Stream C: {what was done} ✓
+
+### Files Modified
+- {consolidated list from all streams}
+
+### Issues Encountered
+- {any blockers or problems}
+
+### Test Results
+- {combined test results if applicable}
+
+### Git Status
+- Commits made: {count}
+- Current branch: {branch}
+- Clean working tree: {yes/no}
+
+### Overall Status
+{Complete/Partially Complete/Blocked}
+
+### Next Steps
+{What should happen next}
+```
+
+## Execution Pattern
+
+1. **Setup Phase**
+   - Verify worktree exists and is clean
+   - Read issue requirements and analysis
+   - Plan execution order based on dependencies
+
+2. **Parallel Execution Phase**
+   - Spawn all independent streams simultaneously
+   - Wait for responses
+   - As streams complete, check if new streams can start
+   - Continue until all streams are processed
+
+3. **Consolidation Phase**
+   - Gather all sub-agent results
+   - Check git status in worktree
+   - Prepare consolidated summary
+   - Return to main thread
+
+## Context Management
+
+**Critical**: Your role is to shield the main thread from implementation details.
+
+- Main thread should NOT see:
+  - Individual code changes
+  - Detailed implementation steps
+  - Full file contents
+  - Verbose error messages
+
+- Main thread SHOULD see:
+  - What was accomplished
+  - Overall status
+  - Critical blockers
+  - Next recommended action
+
+## Coordination Strategies
+
+When sub-agents report conflicts:
+1. Note which files are contested
+2. Serialize access (have one complete, then the other)
+3. Report any unresolveable conflicts up to main thread
+
+When sub-agents report blockers:
+1. Check if other streams can provide the blocker
+2. If not, note it in final summary for human intervention
+3. Continue with other streams
+
+## Error Handling
+
+If a sub-agent fails:
+- Note the failure
+- Continue with other streams
+- Report failure in summary with enough context for debugging
+
+If worktree has conflicts:
+- Stop execution
+- Report state clearly
+- Request human intervention
+
+## Important Notes
+
+- Each sub-agent works independently - they don't communicate directly
+- You are the coordination point - consolidate and resolve when possible
+- Keep the main thread summary extremely concise
+- If all streams complete successfully, just report success
+- If issues arise, provide actionable information
+
+Your goal: Execute maximum parallel work while maintaining a clean, simple interface to the main thread. The complexity of parallel execution should be invisible above you.

+
+You are an expert test execution and analysis specialist for the MUXI Runtime system. Your primary responsibility is to efficiently run tests, capture comprehensive logs, and provide actionable insights from test results.
+
+## Core Responsibilities
+
+1. **Test Execution**: You will run tests using the optimized test runner script that automatically captures logs. Always use `.claude/scripts/test-and-log.sh` to ensure full output capture.
+
+2. **Log Analysis**: After test execution, you will analyze the captured logs to identify:
+   - Test failures and their root causes
+   - Performance bottlenecks or timeouts
+   - Resource issues (memory leaks, connection exhaustion)
+   - Flaky test patterns
+   - Configuration problems
+   - Missing dependencies or setup issues
+
+3. **Issue Prioritization**: You will categorize issues by severity:
+   - **Critical**: Tests that block deployment or indicate data corruption
+   - **High**: Consistent failures affecting core functionality
+   - **Medium**: Intermittent failures or performance degradation
+   - **Low**: Minor issues or test infrastructure problems
+
+## Execution Workflow
+
+1. **Pre-execution Checks**:
+   - Verify test file exists and is executable
+   - Check for required environment variables
+   - Ensure test dependencies are available
+
+2. **Test Execution**:
+
+   ```bash
+   # Standard execution with automatic log naming
+   .claude/scripts/test-and-log.sh tests/[test_file].py
+
+   # For iteration testing with custom log names
+   .claude/scripts/test-and-log.sh tests/[test_file].py [test_name]_iteration_[n].log
+   ```
+
+3. **Log Analysis Process**:
+   - Parse the log file for test results summary
+   - Identify all ERROR and FAILURE entries
+   - Extract stack traces and error messages
+   - Look for patterns in failures (timing, resources, dependencies)
+   - Check for warnings that might indicate future problems
+
+4. **Results Reporting**:
+   - Provide a concise summary of test results (passed/failed/skipped)
+   - List critical failures with their root causes
+   - Suggest specific fixes or debugging steps
+   - Highlight any environmental or configuration issues
+   - Note any performance concerns or resource problems
+
+## Analysis Patterns
+
+When analyzing logs, you will look for:
+
+- **Assertion Failures**: Extract the expected vs actual values
+- **Timeout Issues**: Identify operations taking too long
+- **Connection Errors**: Database, API, or service connectivity problems
+- **Import Errors**: Missing modules or circular dependencies
+- **Configuration Issues**: Invalid or missing configuration values
+- **Resource Exhaustion**: Memory, file handles, or connection pool issues
+- **Concurrency Problems**: Deadlocks, race conditions, or synchronization issues
+
+**IMPORTANT**:
+Ensure you read the test carefully to understand what it is testing, so you can better analyze the results.
+
+## Output Format
+
+Your analysis should follow this structure:
+
+```
+## Test Execution Summary
+- Total Tests: X
+- Passed: X
+- Failed: X
+- Skipped: X
+- Duration: Xs
+
+## Critical Issues
+[List any blocking issues with specific error messages and line numbers]
+
+## Test Failures
+[For each failure:
+ - Test name
+ - Failure reason
+ - Relevant error message/stack trace
+ - Suggested fix]
+
+## Warnings & Observations
+[Non-critical issues that should be addressed]
+
+## Recommendations
+[Specific actions to fix failures or improve test reliability]
+```
+
+## Special Considerations
+
+- For flaky tests, suggest running multiple iterations to confirm intermittent behavior
+- When tests pass but show warnings, highlight these for preventive maintenance
+- If all tests pass, still check for performance degradation or resource usage patterns
+- For configuration-related failures, provide the exact configuration changes needed
+- When encountering new failure patterns, suggest additional diagnostic steps
+
+## Error Recovery
+
+If the test runner script fails to execute:
+1. Check if the script has execute permissions
+2. Verify the test file path is correct
+3. Ensure the logs directory exists and is writable
+4. Fall back to direct pytest execution with output redirection if necessary
+
+You will maintain context efficiency by keeping the main conversation focused on actionable insights while ensuring all diagnostic information is captured in the logs for detailed debugging when needed.

+# CodeRabbit Review Handler
+
+Process CodeRabbit review comments with context-aware discretion.
+
+## Usage
+```
+/code-rabbit
+```
+
+Then paste one or more CodeRabbit comments.
+
+## Instructions
+
+### 1. Initial Context
+
+Inform the user:
+```
+I'll review the CodeRabbit comments with discretion, as CodeRabbit doesn't have access to the entire codebase and may not understand the full context.
+
+For each comment, I'll:
+- Evaluate if it's valid given our codebase context
+- Accept suggestions that improve code quality
+- Ignore suggestions that don't apply to our architecture
+- Explain my reasoning for accept/ignore decisions
+```
+
+### 2. Process Comments
+
+#### Single File Comments
+If all comments relate to one file:
+- Read the file for context
+- Evaluate each suggestion
+- Apply accepted changes in batch using MultiEdit
+- Report which suggestions were accepted/ignored and why
+
+#### Multiple File Comments
+If comments span multiple files:
+
+Launch parallel sub-agents using Task tool:
+```yaml
+Task:
+  description: "CodeRabbit fixes for {filename}"
+  subagent_type: "general-purpose"
+  prompt: |
+    Review and apply CodeRabbit suggestions for {filename}.
+    
+    Comments to evaluate:
+    {relevant_comments_for_this_file}
+    
+    Instructions:
+    1. Read the file to understand context
+    2. For each suggestion:
+       - Evaluate validity given codebase patterns
+       - Accept if it improves quality/correctness
+       - Ignore if not applicable
+    3. Apply accepted changes using Edit/MultiEdit
+    4. Return summary:
+       - Accepted: {list with reasons}
+       - Ignored: {list with reasons}
+       - Changes made: {brief description}
+    
+    Use discretion - CodeRabbit lacks full context.
+```
+
+### 3. Consolidate Results
+
+After all sub-agents complete:
+```
+📋 CodeRabbit Review Summary
+
+Files Processed: {count}
+
+Accepted Suggestions:
+  {file}: {changes_made}
+  
+Ignored Suggestions:
+  {file}: {reason_ignored}
+
+Overall: {X}/{Y} suggestions applied
+```
+
+### 4. Common Patterns to Ignore
+
+- **Style preferences** that conflict with project conventions
+- **Generic best practices** that don't apply to our specific use case
+- **Performance optimizations** for code that isn't performance-critical
+- **Accessibility suggestions** for internal tools
+- **Security warnings** for already-validated patterns
+- **Import reorganization** that would break our structure
+
+### 5. Common Patterns to Accept
+
+- **Actual bugs** (null checks, error handling)
+- **Security vulnerabilities** (unless false positive)
+- **Resource leaks** (unclosed connections, memory leaks)
+- **Type safety issues** (TypeScript/type hints)
+- **Logic errors** (off-by-one, incorrect conditions)
+- **Missing error handling** 
+
+## Decision Framework
+
+For each suggestion, consider:
+1. **Is it correct?** - Does the issue actually exist?
+2. **Is it relevant?** - Does it apply to our use case?
+3. **Is it beneficial?** - Will fixing it improve the code?
+4. **Is it safe?** - Could the change introduce problems?
+
+Only apply if all answers are "yes" or the benefit clearly outweighs risks.
+
+## Important Notes
+
+- CodeRabbit is helpful but lacks context
+- Trust your understanding of the codebase over generic suggestions
+- Explain decisions briefly to maintain audit trail
+- Batch related changes for efficiency
+- Use parallel agents for multi-file reviews to save time

+# Create Initial Context
+
+This command creates the initial project context documentation in `.claude/context/` by analyzing the current project state and establishing comprehensive baseline documentation.
+
+## Required Rules
+
+**IMPORTANT:** Before executing this command, read and follow:
+- `.claude/rules/datetime.md` - For getting real current date/time
+
+## Preflight Checklist
+
+Before proceeding, complete these validation steps.
+Do not bother the user with preflight checks progress ("I'm not going to ..."). Just do them and move on.
+
+### 1. Context Directory Check
+- Run: `ls -la .claude/context/ 2>/dev/null`
+- If directory exists and has files:
+  - Count existing files: `ls -1 .claude/context/*.md 2>/dev/null | wc -l`
+  - Ask user: "⚠️ Found {count} existing context files. Overwrite all context? (yes/no)"
+  - Only proceed with explicit 'yes' confirmation
+  - If user says no, suggest: "Use /context:update to refresh existing context"
+
+### 2. Project Type Detection
+- Check for project indicators:
+  - Node.js: `test -f package.json && echo "Node.js project detected"`
+  - Python: `test -f requirements.txt || test -f pyproject.toml && echo "Python project detected"`
+  - Rust: `test -f Cargo.toml && echo "Rust project detected"`
+  - Go: `test -f go.mod && echo "Go project detected"`
+- Run: `git status 2>/dev/null` to confirm this is a git repository
+- If not a git repo, ask: "⚠️ Not a git repository. Continue anyway? (yes/no)"
+
+### 3. Directory Creation
+- If `.claude/` doesn't exist, create it: `mkdir -p .claude/context/`
+- Verify write permissions: `touch .claude/context/.test && rm .claude/context/.test`
+- If permission denied, tell user: "❌ Cannot create context directory. Check permissions."
+
+### 4. Get Current DateTime
+- Run: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+- Store this value for use in all context file frontmatter
+
+## Instructions
+
+### 1. Pre-Analysis Validation
+- Confirm project root directory is correct (presence of .git, package.json, etc.)
+- Check for existing documentation that can inform context (README.md, docs/)
+- If README.md doesn't exist, ask user for project description
+
+### 2. Systematic Project Analysis
+Gather information in this order:
+
+**Project Detection:**
+- Run: `find . -maxdepth 2 -name 'package.json' -o -name 'requirements.txt' -o -name 'Cargo.toml' -o -name 'go.mod' 2>/dev/null`
+- Run: `git remote -v 2>/dev/null` to get repository information
+- Run: `git branch --show-current 2>/dev/null` to get current branch
+
+**Codebase Analysis:**
+- Run: `find . -type f -name '*.js' -o -name '*.py' -o -name '*.rs' -o -name '*.go' 2>/dev/null | head -20`
+- Run: `ls -la` to see root directory structure
+- Read README.md if it exists
+
+### 3. Context File Creation with Frontmatter
+
+Each context file MUST include frontmatter with real datetime:
+
+```yaml
+---
+created: [Use REAL datetime from date command]
+last_updated: [Use REAL datetime from date command]
+version: 1.0
+author: Claude Code PM System
+---
+```
+
+Generate the following initial context files:
+  - `progress.md` - Document current project status, completed work, and immediate next steps
+    - Include: Current branch, recent commits, outstanding changes
+  - `project-structure.md` - Map out the directory structure and file organization
+    - Include: Key directories, file naming patterns, module organization
+  - `tech-context.md` - Catalog current dependencies, technologies, and development tools
+    - Include: Language version, framework versions, dev dependencies
+  - `system-patterns.md` - Identify existing architectural patterns and design decisions
+    - Include: Design patterns observed, architectural style, data flow
+  - `product-context.md` - Define product requirements, target users, and core functionality
+    - Include: User personas, core features, use cases
+  - `project-brief.md` - Establish project scope, goals, and key objectives
+    - Include: What it does, why it exists, success criteria
+  - `project-overview.md` - Provide a high-level summary of features and capabilities
+    - Include: Feature list, current state, integration points
+  - `project-vision.md` - Articulate long-term vision and strategic direction
+    - Include: Future goals, potential expansions, strategic priorities
+  - `project-style-guide.md` - Document coding standards, conventions, and style preferences
+    - Include: Naming conventions, file structure patterns, comment style
+### 4. Quality Validation
+
+After creating each file:
+- Verify file was created successfully
+- Check file is not empty (minimum 10 lines of content)
+- Ensure frontmatter is present and valid
+- Validate markdown formatting is correct
+
+### 5. Error Handling
+
+**Common Issues:**
+- **No write permissions:** "❌ Cannot write to .claude/context/. Check permissions."
+- **Disk space:** "❌ Insufficient disk space for context files."
+- **File creation failed:** "❌ Failed to create {filename}. Error: {error}"
+
+If any file fails to create:
+- Report which files were successfully created
+- Provide option to continue with partial context
+- Never leave corrupted or incomplete files
+
+### 6. Post-Creation Summary
+
+Provide comprehensive summary:
+```
+📋 Context Creation Complete
+
+📁 Created context in: .claude/context/
+✅ Files created: {count}/9
+
+📊 Context Summary:
+  - Project Type: {detected_type}
+  - Language: {primary_language}
+  - Git Status: {clean/changes}
+  - Dependencies: {count} packages
+
+📝 File Details:
+  ✅ progress.md ({lines} lines) - Current status and recent work
+  ✅ project-structure.md ({lines} lines) - Directory organization
+  [... list all files with line counts and brief description ...]
+
+⏰ Created: {timestamp}
+🔄 Next: Use /context:prime to load context in new sessions
+💡 Tip: Run /context:update regularly to keep context current
+```
+
+## Context Gathering Commands
+
+Use these commands to gather project information:
+- Target directory: `.claude/context/` (create if needed)
+- Current git status: `git status --short`
+- Recent commits: `git log --oneline -10`
+- Project README: Read `README.md` if exists
+- Package files: Check for `package.json`, `requirements.txt`, `Cargo.toml`, `go.mod`, etc.
+- Documentation scan: `find . -type f -name '*.md' -path '*/docs/*' 2>/dev/null | head -10`
+- Test detection: `find . -type d \( -name 'test' -o -name 'tests' -o -name '__tests__' -o -name 'spec' \) 2>/dev/null | head -5`
+
+## Important Notes
+
+- **Always use real datetime** from system clock, never placeholders
+- **Ask for confirmation** before overwriting existing context
+- **Validate each file** is created successfully
+- **Provide detailed summary** of what was created
+- **Handle errors gracefully** with specific guidance

+# Prime Context
+
+This command loads essential context for a new agent session by reading the project context documentation and understanding the codebase structure.
+
+## Preflight Checklist
+
+Before proceeding, complete these validation steps.
+Do not bother the user with preflight checks progress ("I'm not going to ..."). Just do them and move on.
+
+### 1. Context Availability Check
+- Run: `ls -la .claude/context/ 2>/dev/null`
+- If directory doesn't exist or is empty:
+  - Tell user: "❌ No context found. Please run /context:create first to establish project context."
+  - Exit gracefully
+- Count available context files: `ls -1 .claude/context/*.md 2>/dev/null | wc -l`
+- Report: "📁 Found {count} context files to load"
+
+### 2. File Integrity Check
+- For each context file found:
+  - Verify file is readable: `test -r ".claude/context/{file}" && echo "readable"`
+  - Check file has content: `test -s ".claude/context/{file}" && echo "has content"`
+  - Check for valid frontmatter (should start with `---`)
+- Report any issues:
+  - Empty files: "⚠️ {filename} is empty (skipping)"
+  - Unreadable files: "⚠️ Cannot read {filename} (permission issue)"
+  - Missing frontmatter: "⚠️ {filename} missing frontmatter (may be corrupted)"
+
+### 3. Project State Check
+- Run: `git status --short 2>/dev/null` to see current state
+- Run: `git branch --show-current 2>/dev/null` to get current branch
+- Note if not in git repository (context may be less complete)
+
+## Instructions
+
+### 1. Context Loading Sequence
+
+Load context files in priority order for optimal understanding:
+
+**Priority 1 - Essential Context (load first):**
+1. `project-overview.md` - High-level understanding of the project
+2. `project-brief.md` - Core purpose and goals
+3. `tech-context.md` - Technical stack and dependencies
+
+**Priority 2 - Current State (load second):**
+4. `progress.md` - Current status and recent work
+5. `project-structure.md` - Directory and file organization
+
+**Priority 3 - Deep Context (load third):**
+6. `system-patterns.md` - Architecture and design patterns
+7. `product-context.md` - User needs and requirements
+8. `project-style-guide.md` - Coding conventions
+9. `project-vision.md` - Long-term direction
+
+### 2. Validation During Loading
+
+For each file loaded:
+- Check frontmatter exists and parse:
+  - `created` date should be valid
+  - `last_updated` should be ≥ created date
+  - `version` should be present
+- If frontmatter is invalid, note but continue loading content
+- Track which files loaded successfully vs failed
+
+### 3. Supplementary Information
+
+After loading context files:
+- Run: `git ls-files --others --exclude-standard | head -20` to see untracked files
+- Read `README.md` if it exists for additional project information
+- Check for `.env.example` or similar for environment setup needs
+
+### 4. Error Recovery
+
+**If critical files are missing:**
+- `project-overview.md` missing: Try to understand from README.md
+- `tech-context.md` missing: Analyze package.json/requirements.txt directly
+- `progress.md` missing: Check recent git commits for status
+
+**If context is incomplete:**
+- Inform user which files are missing
+- Suggest running `/context:update` to refresh context
+- Continue with partial context but note limitations
+
+### 5. Loading Summary
+
+Provide comprehensive summary after priming:
+
+```
+🧠 Context Primed Successfully
+
+📖 Loaded Context Files:
+  ✅ Essential: {count}/3 files
+  ✅ Current State: {count}/2 files
+  ✅ Deep Context: {count}/4 files
+
+🔍 Project Understanding:
+  - Name: {project_name}
+  - Type: {project_type}
+  - Language: {primary_language}
+  - Status: {current_status from progress.md}
+  - Branch: {git_branch}
+
+📊 Key Metrics:
+  - Last Updated: {most_recent_update}
+  - Context Version: {version}
+  - Files Loaded: {success_count}/{total_count}
+
+⚠️ Warnings:
+  {list any missing files or issues}
+
+🎯 Ready State:
+  ✅ Project context loaded
+  ✅ Current status understood
+  ✅ Ready for development work
+
+💡 Project Summary:
+  {2-3 sentence summary of what the project is and current state}
+```
+
+### 6. Partial Context Handling
+
+If some files fail to load:
+- Continue with available context
+- Clearly note what's missing
+- Suggest remediation:
+  - "Missing technical context - run /context:create to rebuild"
+  - "Progress file corrupted - run /context:update to refresh"
+
+### 7. Performance Optimization
+
+For large contexts:
+- Load files in parallel when possible
+- Show progress indicator: "Loading context files... {current}/{total}"
+- Skip extremely large files (>10000 lines) with warning
+- Cache parsed frontmatter for faster subsequent loads
+
+## Important Notes
+
+- **Always validate** files before attempting to read
+- **Load in priority order** to get essential context first
+- **Handle missing files gracefully** - don't fail completely
+- **Provide clear summary** of what was loaded and project state
+- **Note any issues** that might affect development work

+# Update Context
+
+This command updates the project context documentation in `.claude/context/` to reflect the current state of the project. Run this at the end of each development session to keep context accurate.
+
+## Required Rules
+
+**IMPORTANT:** Before executing this command, read and follow:
+- `.claude/rules/datetime.md` - For getting real current date/time
+
+## Preflight Checklist
+
+Before proceeding, complete these validation steps.
+Do not bother the user with preflight checks progress ("I'm not going to ..."). Just do them and move on.
+
+### 1. Context Validation
+- Run: `ls -la .claude/context/ 2>/dev/null`
+- If directory doesn't exist or is empty:
+  - Tell user: "❌ No context to update. Please run /context:create first."
+  - Exit gracefully
+- Count existing files: `ls -1 .claude/context/*.md 2>/dev/null | wc -l`
+- Report: "📁 Found {count} context files to check for updates"
+
+### 2. Change Detection
+
+Gather information about what has changed:
+
+**Git Changes:**
+- Run: `git status --short` to see uncommitted changes
+- Run: `git log --oneline -10` to see recent commits
+- Run: `git diff --stat HEAD~5..HEAD 2>/dev/null` to see files changed recently
+
+**File Modifications:**
+- Check context file ages: `find .claude/context -name "*.md" -type f -exec ls -lt {} + | head -5`
+- Note which context files are oldest and may need updates
+
+**Dependency Changes:**
+- Node.js: `git diff HEAD~5..HEAD package.json 2>/dev/null`
+- Python: `git diff HEAD~5..HEAD requirements.txt 2>/dev/null`
+- Check if new dependencies were added or versions changed
+
+### 3. Get Current DateTime
+- Run: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+- Store for updating `last_updated` field in modified files
+
+## Instructions
+
+### 1. Systematic Change Analysis
+
+For each context file, determine if updates are needed:
+
+**Check each file systematically:**
+#### `progress.md` - **Always Update**
+  - Check: Recent commits, current branch, uncommitted changes
+  - Update: Latest completed work, current blockers, next steps
+  - Run: `git log --oneline -5` to get recent commit messages
+  - Include completion percentages if applicable
+
+#### `project-structure.md` - **Update if Changed**
+  - Check: `git diff --name-status HEAD~10..HEAD | grep -E '^A'` for new files
+  - Update: New directories, moved files, structural reorganization
+  - Only update if significant structural changes occurred
+
+#### `tech-context.md` - **Update if Dependencies Changed**
+  - Check: Package files for new dependencies or version changes
+  - Update: New libraries, upgraded versions, new dev tools
+  - Include security updates or breaking changes
+
+#### `system-patterns.md` - **Update if Architecture Changed**
+  - Check: New design patterns, architectural decisions
+  - Update: New patterns adopted, refactoring done
+  - Only update for significant architectural changes
+
+#### `product-context.md` - **Update if Requirements Changed**
+  - Check: New features implemented, user feedback incorporated
+  - Update: New user stories, changed requirements
+  - Include any pivot in product direction
+
+#### `project-brief.md` - **Rarely Update**
+  - Check: Only if fundamental project goals changed
+  - Update: Major scope changes, new objectives
+  - Usually remains stable
+
+#### `project-overview.md` - **Update for Major Milestones**
+  - Check: Major features completed, significant progress
+  - Update: Feature status, capability changes
+  - Update when reaching project milestones
+
+#### `project-vision.md` - **Rarely Update**
+  - Check: Strategic direction changes
+  - Update: Only for major vision shifts
+  - Usually remains stable
+
+#### `project-style-guide.md` - **Update if Conventions Changed**
+  - Check: New linting rules, style decisions
+  - Update: Convention changes, new patterns adopted
+  - Include examples of new patterns
+### 2. Smart Update Strategy
+
+**For each file that needs updating:**
+
+1. **Read existing file** to understand current content
+2. **Identify specific sections** that need updates
+3. **Preserve frontmatter** but update `last_updated` field:
+   ```yaml
+   ---
+   created: [preserve original]
+   last_updated: [Use REAL datetime from date command]
+   version: [increment if major update, e.g., 1.0 → 1.1]
+   author: Claude Code PM System
+   ---
+   ```
+4. **Make targeted updates** - don't rewrite entire file
+5. **Add update notes** at the bottom if significant:
+   ```markdown
+   ## Update History
+   - {date}: {summary of what changed}
+   ```
+
+### 3. Update Validation
+
+After updating each file:
+- Verify file still has valid frontmatter
+- Check file size is reasonable (not corrupted)
+- Ensure markdown formatting is preserved
+- Confirm updates accurately reflect changes
+
+### 4. Skip Optimization
+
+**Skip files that don't need updates:**
+- If no relevant changes detected, skip the file
+- Report skipped files in summary
+- Don't update timestamp if content unchanged
+- This preserves accurate "last modified" information
+
+### 5. Error Handling
+
+**Common Issues:**
+- **File locked:** "❌ Cannot update {file} - may be open in editor"
+- **Permission denied:** "❌ Cannot write to {file} - check permissions"
+- **Corrupted file:** "⚠️ {file} appears corrupted - skipping update"
+- **Disk space:** "❌ Insufficient disk space for updates"
+
+If update fails:
+- Report which files were successfully updated
+- Note which files failed and why
+- Preserve original files (don't leave corrupted state)
+
+### 6. Update Summary
+
+Provide detailed summary of updates:
+
+```
+🔄 Context Update Complete
+
+📊 Update Statistics:
+  - Files Scanned: {total_count}
+  - Files Updated: {updated_count}
+  - Files Skipped: {skipped_count} (no changes needed)
+  - Errors: {error_count}
+
+📝 Updated Files:
+  ✅ progress.md - Updated recent commits, current status
+  ✅ tech-context.md - Added 3 new dependencies
+  ✅ project-structure.md - Noted new /utils directory
+
+⏭️ Skipped Files (no changes):
+  - project-brief.md (last updated: 5 days ago)
+  - project-vision.md (last updated: 2 weeks ago)
+  - system-patterns.md (last updated: 3 days ago)
+
+⚠️ Issues:
+  {any warnings or errors}
+
+⏰ Last Update: {timestamp}
+🔄 Next: Run this command regularly to keep context current
+💡 Tip: Major changes? Consider running /context:create for full refresh
+```
+
+### 7. Incremental Update Tracking
+
+**Track what was updated:**
+- Note which sections of each file were modified
+- Keep changes focused and surgical
+- Don't regenerate unchanged content
+- Preserve formatting and structure
+
+### 8. Performance Optimization
+
+For large projects:
+- Process files in parallel when possible
+- Show progress: "Updating context files... {current}/{total}"
+- Skip very large files with warning
+- Use git diff to quickly identify changed areas
+
+## Context Gathering Commands
+
+Use these commands to detect changes:
+- Context directory: `.claude/context/`
+- Current git status: `git status --short`
+- Recent commits: `git log --oneline -10`
+- Changed files: `git diff --name-only HEAD~5..HEAD 2>/dev/null`
+- Branch info: `git branch --show-current`
+- Uncommitted changes: `git diff --stat`
+- New untracked files: `git ls-files --others --exclude-standard | head -10`
+- Dependency changes: Check package.json, requirements.txt, etc.
+
+## Important Notes
+
+- **Only update files with actual changes** - preserve accurate timestamps
+- **Always use real datetime** from system clock for `last_updated`
+- **Make surgical updates** - don't regenerate entire files
+- **Validate each update** - ensure files remain valid
+- **Provide detailed summary** - show what changed and what didn't
+- **Handle errors gracefully** - don't corrupt existing context

+```
+
+## Required Rules
+
+**IMPORTANT:** Before executing this command, read and follow:
+- `.claude/rules/datetime.md` - For getting real current date/time
+
+## Preflight Checklist
+
+Before proceeding, complete these validation steps.
+Do not bother the user with preflight checks progress ("I'm not going to ..."). Just do them and move on.
+
+1. **Verify epic exists:**
+   - Check if `.claude/epics/$ARGUMENTS/epic.md` exists
+   - If not found, tell user: "❌ Epic not found: $ARGUMENTS. First create it with: /pm:prd-parse $ARGUMENTS"
+   - Stop execution if epic doesn't exist
+
+2. **Check for existing tasks:**
+   - Check if any numbered task files (001.md, 002.md, etc.) already exist in `.claude/epics/$ARGUMENTS/`
+   - If tasks exist, list them and ask: "⚠️ Found {count} existing tasks. Delete and recreate all tasks? (yes/no)"
+   - Only proceed with explicit 'yes' confirmation
+   - If user says no, suggest: "View existing tasks with: /pm:epic-show $ARGUMENTS"
+
+3. **Validate epic frontmatter:**
+   - Verify epic has valid frontmatter with: name, status, created, prd
+   - If invalid, tell user: "❌ Invalid epic frontmatter. Please check: .claude/epics/$ARGUMENTS/epic.md"
+
+4. **Check epic status:**
+   - If epic status is already "completed", warn user: "⚠️ Epic is marked as completed. Are you sure you want to decompose it again?"
+
+## Instructions
+
+You are decomposing an epic into specific, actionable tasks for: **$ARGUMENTS**
+
+### 1. Read the Epic
+- Load the epic from `.claude/epics/$ARGUMENTS/epic.md`
+- Understand the technical approach and requirements
+- Review the task breakdown preview
+
+### 2. Analyze for Parallel Creation
+
+Determine if tasks can be created in parallel:
+- If tasks are mostly independent: Create in parallel using Task agents
+- If tasks have complex dependencies: Create sequentially
+- For best results: Group independent tasks for parallel creation
+
+### 3. Parallel Task Creation (When Possible)
+
+If tasks can be created in parallel, spawn sub-agents:
+
+```yaml
+Task:
+  description: "Create task files batch {X}"
+  subagent_type: "general-purpose"
+  prompt: |
+    Create task files for epic: $ARGUMENTS
+
+    Tasks to create:
+    - {list of 3-4 tasks for this batch}
+
+    For each task:
+    1. Create file: .claude/epics/$ARGUMENTS/{number}.md
+    2. Use exact format with frontmatter and all sections
+    3. Follow task breakdown from epic
+    4. Set parallel/depends_on fields appropriately
+    5. Number sequentially (001.md, 002.md, etc.)
+
+    Return: List of files created
+```
+
+### 4. Task File Format with Frontmatter
+For each task, create a file with this exact structure:
+
+```markdown
+---
+name: [Task Title]
+status: open
+created: [Current ISO date/time]
+updated: [Current ISO date/time]
+github: [Will be updated when synced to GitHub]
+depends_on: []  # List of task numbers this depends on, e.g., [001, 002]
+parallel: true  # Can this run in parallel with other tasks?
+conflicts_with: []  # Tasks that modify same files, e.g., [003, 004]
+---
+
+# Task: [Task Title]
+
+## Description
+Clear, concise description of what needs to be done
+
+## Acceptance Criteria
+- [ ] Specific criterion 1
+- [ ] Specific criterion 2
+- [ ] Specific criterion 3
+
+## Technical Details
+- Implementation approach
+- Key considerations
+- Code locations/files affected
+
+## Dependencies
+- [ ] Task/Issue dependencies
+- [ ] External dependencies
+
+## Effort Estimate
+- Size: XS/S/M/L/XL
+- Hours: estimated hours
+- Parallel: true/false (can run in parallel with other tasks)
+
+## Definition of Done
+- [ ] Code implemented
+- [ ] Tests written and passing
+- [ ] Documentation updated
+- [ ] Code reviewed
+- [ ] Deployed to staging
+```
+
+### 3. Task Naming Convention
+Save tasks as: `.claude/epics/$ARGUMENTS/{task_number}.md`
+- Use sequential numbering: 001.md, 002.md, etc.
+- Keep task titles short but descriptive
+
+### 4. Frontmatter Guidelines
+- **name**: Use a descriptive task title (without "Task:" prefix)
+- **status**: Always start with "open" for new tasks
+- **created**: Get REAL current datetime by running: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+- **updated**: Use the same real datetime as created for new tasks
+- **github**: Leave placeholder text - will be updated during sync
+- **depends_on**: List task numbers that must complete before this can start (e.g., [001, 002])
+- **parallel**: Set to true if this can run alongside other tasks without conflicts
+- **conflicts_with**: List task numbers that modify the same files (helps coordination)
+
+### 5. Task Types to Consider
+- **Setup tasks**: Environment, dependencies, scaffolding
+- **Data tasks**: Models, schemas, migrations
+- **API tasks**: Endpoints, services, integration
+- **UI tasks**: Components, pages, styling
+- **Testing tasks**: Unit tests, integration tests
+- **Documentation tasks**: README, API docs
+- **Deployment tasks**: CI/CD, infrastructure
+
+### 6. Parallelization
+Mark tasks with `parallel: true` if they can be worked on simultaneously without conflicts.
+
+### 7. Execution Strategy
+
+Choose based on task count and complexity:
+
+**Small Epic (< 5 tasks)**: Create sequentially for simplicity
+
+**Medium Epic (5-10 tasks)**:
+- Batch into 2-3 groups
+- Spawn agents for each batch
+- Consolidate results
+
+**Large Epic (> 10 tasks)**:
+- Analyze dependencies first
+- Group independent tasks
+- Launch parallel agents (max 5 concurrent)
+- Create dependent tasks after prerequisites
+
+Example for parallel execution:
+```markdown
+Spawning 3 agents for parallel task creation:
+- Agent 1: Creating tasks 001-003 (Database layer)
+- Agent 2: Creating tasks 004-006 (API layer)
+- Agent 3: Creating tasks 007-009 (UI layer)
+```
+
+### 8. Task Dependency Validation
+
+When creating tasks with dependencies:
+- Ensure referenced dependencies exist (e.g., if Task 003 depends on Task 002, verify 002 was created)
+- Check for circular dependencies (Task A → Task B → Task A)
+- If dependency issues found, warn but continue: "⚠️ Task dependency warning: {details}"
+
+### 9. Update Epic with Task Summary
+After creating all tasks, update the epic file by adding this section:
+```markdown
+## Tasks Created
+- [ ] 001.md - {Task Title} (parallel: true/false)
+- [ ] 002.md - {Task Title} (parallel: true/false)
+- etc.
+
+Total tasks: {count}
+Parallel tasks: {parallel_count}
+Sequential tasks: {sequential_count}
+Estimated total effort: {sum of hours}
+```
+
+Also update the epic's frontmatter progress if needed (still 0% until tasks actually start).
+
+### 9. Quality Validation
+
+Before finalizing tasks, verify:
+- [ ] All tasks have clear acceptance criteria
+- [ ] Task sizes are reasonable (1-3 days each)
+- [ ] Dependencies are logical and achievable
+- [ ] Parallel tasks don't conflict with each other
+- [ ] Combined tasks cover all epic requirements
+
+### 10. Post-Decomposition
+
+After successfully creating tasks:
+1. Confirm: "✅ Created {count} tasks for epic: $ARGUMENTS"
+2. Show summary:
+   - Total tasks created
+   - Parallel vs sequential breakdown
+   - Total estimated effort
+3. Suggest next step: "Ready to sync to GitHub? Run: /pm:epic-sync $ARGUMENTS"
+
+## Error Recovery
+
+If any step fails:
+- If task creation partially completes, list which tasks were created
+- Provide option to clean up partial tasks
+- Never leave the epic in an inconsistent state
+
+Aim for tasks that can be completed in 1-3 days each. Break down larger tasks into smaller, manageable pieces for the "$ARGUMENTS" epic.

+# Epic Merge
+
+Merge completed epic from worktree back to main branch.
+
+## Usage
+```
+/pm:epic-merge <epic_name>
+```
+
+## Quick Check
+
+1. **Verify worktree exists:**
+   ```bash
+   git worktree list | grep "epic-$ARGUMENTS" || echo "❌ No worktree for epic: $ARGUMENTS"
+   ```
+
+2. **Check for active agents:**
+   Read `.claude/epics/$ARGUMENTS/execution-status.md`
+   If active agents exist: "⚠️ Active agents detected. Stop them first with: /pm:epic-stop $ARGUMENTS"
+
+## Instructions
+
+### 1. Pre-Merge Validation
+
+Navigate to worktree and check status:
+```bash
+cd ../epic-$ARGUMENTS
+
+# Check for uncommitted changes
+if [[ $(git status --porcelain) ]]; then
+  echo "⚠️ Uncommitted changes in worktree:"
+  git status --short
+  echo "Commit or stash changes before merging"
+  exit 1
+fi
+
+# Check branch status
+git fetch origin
+git status -sb
+```
+
+### 2. Run Tests (Optional but Recommended)
+
+```bash
+# Look for test commands
+if [ -f package.json ]; then
+  npm test || echo "⚠️ Tests failed. Continue anyway? (yes/no)"
+elif [ -f Makefile ]; then
+  make test || echo "⚠️ Tests failed. Continue anyway? (yes/no)"
+fi
+```
+
+### 3. Update Epic Documentation
+
+Get current datetime: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+
+Update `.claude/epics/$ARGUMENTS/epic.md`:
+- Set status to "completed"
+- Update completion date
+- Add final summary
+
+### 4. Attempt Merge
+
+```bash
+# Return to main repository
+cd {main-repo-path}
+
+# Ensure main is up to date
+git checkout main
+git pull origin main
+
+# Attempt merge
+echo "Merging epic/$ARGUMENTS to main..."
+git merge epic/$ARGUMENTS --no-ff -m "Merge epic: $ARGUMENTS
+
+Completed features:
+$(cd .claude/epics/$ARGUMENTS && ls *.md | grep -E '^[0-9]+' | while read f; do
+  echo "- $(grep '^name:' $f | cut -d: -f2)"
+done)
+
+Closes epic #$(grep 'github:' .claude/epics/$ARGUMENTS/epic.md | grep -oE '#[0-9]+')"
+```
+
+### 5. Handle Merge Conflicts
+
+If merge fails with conflicts:
+```bash
+# Check conflict status
+git status
+
+echo "
+❌ Merge conflicts detected!
+
+Conflicts in:
+$(git diff --name-only --diff-filter=U)
+
+Options:
+1. Resolve manually:
+   - Edit conflicted files
+   - git add {files}
+   - git commit
+   
+2. Abort merge:
+   git merge --abort
+   
+3. Get help:
+   /pm:epic-resolve $ARGUMENTS
+
+Worktree preserved at: ../epic-$ARGUMENTS
+"
+exit 1
+```
+
+### 6. Post-Merge Cleanup
+
+If merge succeeds:
+```bash
+# Push to remote
+git push origin main
+
+# Clean up worktree
+git worktree remove ../epic-$ARGUMENTS
+echo "✅ Worktree removed: ../epic-$ARGUMENTS"
+
+# Delete branch
+git branch -d epic/$ARGUMENTS
+git push origin --delete epic/$ARGUMENTS 2>/dev/null || true
+
+# Archive epic locally
+mkdir -p .claude/epics/archived/
+mv .claude/epics/$ARGUMENTS .claude/epics/archived/
+echo "✅ Epic archived: .claude/epics/archived/$ARGUMENTS"
+```
+
+### 7. Update GitHub Issues
+
+Close related issues:
+```bash
+# Get issue numbers from epic
+epic_issue=$(grep 'github:' .claude/epics/archived/$ARGUMENTS/epic.md | grep -oE '[0-9]+$')
+
+# Close epic issue
+gh issue close $epic_issue -c "Epic completed and merged to main"
+
+# Close task issues
+for task_file in .claude/epics/archived/$ARGUMENTS/[0-9]*.md; do
+  issue_num=$(grep 'github:' $task_file | grep -oE '[0-9]+$')
+  if [ ! -z "$issue_num" ]; then
+    gh issue close $issue_num -c "Completed in epic merge"
+  fi
+done
+```
+
+### 8. Final Output
+
+```
+✅ Epic Merged Successfully: $ARGUMENTS
+
+Summary:
+  Branch: epic/$ARGUMENTS → main
+  Commits merged: {count}
+  Files changed: {count}
+  Issues closed: {count}
+  
+Cleanup completed:
+  ✓ Worktree removed
+  ✓ Branch deleted
+  ✓ Epic archived
+  ✓ GitHub issues closed
+  
+Next steps:
+  - Deploy changes if needed
+  - Start new epic: /pm:prd-new {feature}
+  - View completed work: git log --oneline -20
+```
+
+## Conflict Resolution Help
+
+If conflicts need resolution:
+```
+The epic branch has conflicts with main.
+
+This typically happens when:
+- Main has changed since epic started
+- Multiple epics modified same files
+- Dependencies were updated
+
+To resolve:
+1. Open conflicted files
+2. Look for <<<<<<< markers
+3. Choose correct version or combine
+4. Remove conflict markers
+5. git add {resolved files}
+6. git commit
+7. git push
+
+Or abort and try later:
+  git merge --abort
+```
+
+## Important Notes
+
+- Always check for uncommitted changes first
+- Run tests before merging when possible
+- Use --no-ff to preserve epic history
+- Archive epic data instead of deleting
+- Close GitHub issues to maintain sync

+# Epic Oneshot
+
+Decompose epic into tasks and sync to GitHub in one operation.
+
+## Usage
+```
+/pm:epic-oneshot <feature_name>
+```
+
+## Instructions
+
+### 1. Validate Prerequisites
+
+Check that epic exists and hasn't been processed:
+```bash
+# Epic must exist
+test -f .claude/epics/$ARGUMENTS/epic.md || echo "❌ Epic not found. Run: /pm:prd-parse $ARGUMENTS"
+
+# Check for existing tasks
+if ls .claude/epics/$ARGUMENTS/[0-9]*.md 2>/dev/null | grep -q .; then
+  echo "⚠️ Tasks already exist. This will create duplicates."
+  echo "Delete existing tasks or use /pm:epic-sync instead."
+  exit 1
+fi
+
+# Check if already synced
+if grep -q "github:" .claude/epics/$ARGUMENTS/epic.md; then
+  echo "⚠️ Epic already synced to GitHub."
+  echo "Use /pm:epic-sync to update."
+  exit 1
+fi
+```
+
+### 2. Execute Decompose
+
+Simply run the decompose command:
+```
+Running: /pm:epic-decompose $ARGUMENTS
+```
+
+This will:
+- Read the epic
+- Create task files (using parallel agents if appropriate)
+- Update epic with task summary
+
+### 3. Execute Sync
+
+Immediately follow with sync:
+```
+Running: /pm:epic-sync $ARGUMENTS
+```
+
+This will:
+- Create epic issue on GitHub
+- Create sub-issues (using parallel agents if appropriate)
+- Rename task files to issue IDs
+- Create worktree
+
+### 4. Output
+
+```
+🚀 Epic Oneshot Complete: $ARGUMENTS
+
+Step 1: Decomposition ✓
+  - Tasks created: {count}
+  
+Step 2: GitHub Sync ✓
+  - Epic: #{number}
+  - Sub-issues created: {count}
+  - Worktree: ../epic-$ARGUMENTS
+
+Ready for development!
+  Start work: /pm:epic-start $ARGUMENTS
+  Or single task: /pm:issue-start {task_number}
+```
+
+## Important Notes
+
+This is simply a convenience wrapper that runs:
+1. `/pm:epic-decompose` 
+2. `/pm:epic-sync`
+
+Both commands handle their own error checking, parallel execution, and validation. This command just orchestrates them in sequence.
+
+Use this when you're confident the epic is ready and want to go from epic to GitHub issues in one step.

+# Epic Refresh
+
+Update epic progress based on task states.
+
+## Usage
+```
+/pm:epic-refresh <epic_name>
+```
+
+## Instructions
+
+### 1. Count Task Status
+
+Scan all task files in `.claude/epics/$ARGUMENTS/`:
+- Count total tasks
+- Count tasks with `status: closed`
+- Count tasks with `status: open`
+- Count tasks with work in progress
+
+### 2. Calculate Progress
+
+```
+progress = (closed_tasks / total_tasks) * 100
+```
+
+Round to nearest integer.
+
+### 3. Update GitHub Task List
+
+If epic has GitHub issue, sync task checkboxes:
+
+```bash
+# Get epic issue number from epic.md frontmatter
+epic_issue={extract_from_github_field}
+
+if [ ! -z "$epic_issue" ]; then
+  # Get current epic body
+  gh issue view $epic_issue --json body -q .body > /tmp/epic-body.md
+  
+  # For each task, check its status and update checkbox
+  for task_file in .claude/epics/$ARGUMENTS/[0-9]*.md; do
+    task_issue=$(grep 'github:' $task_file | grep -oE '[0-9]+$')
+    task_status=$(grep 'status:' $task_file | cut -d: -f2 | tr -d ' ')
+    
+    if [ "$task_status" = "closed" ]; then
+      # Mark as checked
+      sed -i "s/- \[ \] #$task_issue/- [x] #$task_issue/" /tmp/epic-body.md
+    else
+      # Ensure unchecked (in case manually checked)
+      sed -i "s/- \[x\] #$task_issue/- [ ] #$task_issue/" /tmp/epic-body.md
+    fi
+  done
+  
+  # Update epic issue
+  gh issue edit $epic_issue --body-file /tmp/epic-body.md
+fi
+```
+
+### 4. Determine Epic Status
+
+- If progress = 0% and no work started: `backlog`
+- If progress > 0% and < 100%: `in-progress`
+- If progress = 100%: `completed`
+
+### 5. Update Epic
+
+Get current datetime: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+
+Update epic.md frontmatter:
+```yaml
+status: {calculated_status}
+progress: {calculated_progress}%
+updated: {current_datetime}
+```
+
+### 6. Output
+
+```
+🔄 Epic refreshed: $ARGUMENTS
+
+Tasks:
+  Closed: {closed_count}
+  Open: {open_count}
+  Total: {total_count}
+  
+Progress: {old_progress}% → {new_progress}%
+Status: {old_status} → {new_status}
+GitHub: Task list updated ✓
+
+{If complete}: Run /pm:epic-close $ARGUMENTS to close epic
+{If in progress}: Run /pm:next to see priority tasks
+```
+
+## Important Notes
+
+This is useful after manual task edits or GitHub sync.
+Don't modify task files, only epic status.
+Preserve all other frontmatter fields.

+# Epic Start
+
+Launch parallel agents to work on epic tasks in a shared worktree.
+
+## Usage
+```
+/pm:epic-start <epic_name>
+```
+
+## Quick Check
+
+1. **Verify epic exists:**
+   ```bash
+   test -f .claude/epics/$ARGUMENTS/epic.md || echo "❌ Epic not found. Run: /pm:prd-parse $ARGUMENTS"
+   ```
+
+2. **Check GitHub sync:**
+   Look for `github:` field in epic frontmatter.
+   If missing: "❌ Epic not synced. Run: /pm:epic-sync $ARGUMENTS first"
+
+3. **Check for worktree:**
+   ```bash
+   git worktree list | grep "epic-$ARGUMENTS"
+   ```
+
+## Instructions
+
+### 1. Create or Enter Worktree
+
+Follow `/rules/worktree-operations.md`:
+
+```bash
+# If worktree doesn't exist, create it
+if ! git worktree list | grep -q "epic-$ARGUMENTS"; then
+  git checkout main
+  git pull origin main
+  git worktree add ../epic-$ARGUMENTS -b epic/$ARGUMENTS
+  echo "✅ Created worktree: ../epic-$ARGUMENTS"
+else
+  echo "✅ Using existing worktree: ../epic-$ARGUMENTS"
+fi
+```
+
+### 2. Identify Ready Issues
+
+Read all task files in `.claude/epics/$ARGUMENTS/`:
+- Parse frontmatter for `status`, `depends_on`, `parallel` fields
+- Check GitHub issue status if needed
+- Build dependency graph
+
+Categorize issues:
+- **Ready**: No unmet dependencies, not started
+- **Blocked**: Has unmet dependencies
+- **In Progress**: Already being worked on
+- **Complete**: Finished
+
+### 3. Analyze Ready Issues
+
+For each ready issue without analysis:
+```bash
+# Check for analysis
+if ! test -f .claude/epics/$ARGUMENTS/{issue}-analysis.md; then
+  echo "Analyzing issue #{issue}..."
+  # Run analysis (inline or via Task tool)
+fi
+```
+
+### 4. Launch Parallel Agents
+
+For each ready issue with analysis:
+
+```markdown
+## Starting Issue #{issue}: {title}
+
+Reading analysis...
+Found {count} parallel streams:
+  - Stream A: {description} (Agent-{id})
+  - Stream B: {description} (Agent-{id})
+
+Launching agents in worktree: ../epic-$ARGUMENTS/
+```
+
+Use Task tool to launch each stream:
+```yaml
+Task:
+  description: "Issue #{issue} Stream {X}"
+  subagent_type: "{agent_type}"
+  prompt: |
+    Working in worktree: ../epic-$ARGUMENTS/
+    Issue: #{issue} - {title}
+    Stream: {stream_name}
+
+    Your scope:
+    - Files: {file_patterns}
+    - Work: {stream_description}
+
+    Read full requirements from:
+    - .claude/epics/$ARGUMENTS/{task_file}
+    - .claude/epics/$ARGUMENTS/{issue}-analysis.md
+
+    Follow coordination rules in /rules/agent-coordination.md
+
+    Commit frequently with message format:
+    "Issue #{issue}: {specific change}"
+
+    Update progress in:
+    .claude/epics/$ARGUMENTS/updates/{issue}/stream-{X}.md
+```
+
+### 5. Track Active Agents
+
+Create/update `.claude/epics/$ARGUMENTS/execution-status.md`:
+
+```markdown
+---
+started: {datetime}
+worktree: ../epic-$ARGUMENTS
+branch: epic/$ARGUMENTS
+---
+
+# Execution Status
+
+## Active Agents
+- Agent-1: Issue #1234 Stream A (Database) - Started {time}
+- Agent-2: Issue #1234 Stream B (API) - Started {time}
+- Agent-3: Issue #1235 Stream A (UI) - Started {time}
+
+## Queued Issues
+- Issue #1236 - Waiting for #1234
+- Issue #1237 - Waiting for #1235
+
+## Completed
+- {None yet}
+```
+
+### 6. Monitor and Coordinate
+
+Set up monitoring:
+```bash
+echo "
+Agents launched successfully!
+
+Monitor progress:
+  /pm:epic-status $ARGUMENTS
+

+# Epic Start
+
+Launch parallel agents to work on epic tasks in a shared branch.
+
+## Usage
+```
+/pm:epic-start <epic_name>
+```
+
+## Quick Check
+
+1. **Verify epic exists:**
+   ```bash
+   test -f .claude/epics/$ARGUMENTS/epic.md || echo "❌ Epic not found. Run: /pm:prd-parse $ARGUMENTS"
+   ```
+
+2. **Check GitHub sync:**
+   Look for `github:` field in epic frontmatter.
+   If missing: "❌ Epic not synced. Run: /pm:epic-sync $ARGUMENTS first"
+
+3. **Check for branch:**
+   ```bash
+   git branch -a | grep "epic/$ARGUMENTS"
+   ```
+
+4. **Check for uncommitted changes:**
+   ```bash
+   git status --porcelain
+   ```
+   If output is not empty: "❌ You have uncommitted changes. Please commit or stash them before starting an epic"
+
+## Instructions
+
+### 1. Create or Enter Branch
+
+Follow `/rules/branch-operations.md`:
+
+```bash
+# Check for uncommitted changes
+if [ -n "$(git status --porcelain)" ]; then
+  echo "❌ You have uncommitted changes. Please commit or stash them before starting an epic."
+  exit 1
+fi
+
+# If branch doesn't exist, create it
+if ! git branch -a | grep -q "epic/$ARGUMENTS"; then
+  git checkout main
+  git pull origin main
+  git checkout -b epic/$ARGUMENTS
+  git push -u origin epic/$ARGUMENTS
+  echo "✅ Created branch: epic/$ARGUMENTS"
+else
+  git checkout epic/$ARGUMENTS
+  git pull origin epic/$ARGUMENTS
+  echo "✅ Using existing branch: epic/$ARGUMENTS"
+fi
+```
+
+### 2. Identify Ready Issues
+
+Read all task files in `.claude/epics/$ARGUMENTS/`:
+- Parse frontmatter for `status`, `depends_on`, `parallel` fields
+- Check GitHub issue status if needed
+- Build dependency graph
+
+Categorize issues:
+- **Ready**: No unmet dependencies, not started
+- **Blocked**: Has unmet dependencies
+- **In Progress**: Already being worked on
+- **Complete**: Finished
+
+### 3. Analyze Ready Issues
+
+For each ready issue without analysis:
+```bash
+# Check for analysis
+if ! test -f .claude/epics/$ARGUMENTS/{issue}-analysis.md; then
+  echo "Analyzing issue #{issue}..."
+  # Run analysis (inline or via Task tool)
+fi
+```
+
+### 4. Launch Parallel Agents
+
+For each ready issue with analysis:
+
+```markdown
+## Starting Issue #{issue}: {title}
+
+Reading analysis...
+Found {count} parallel streams:
+  - Stream A: {description} (Agent-{id})
+  - Stream B: {description} (Agent-{id})
+
+Launching agents in branch: epic/$ARGUMENTS
+```
+
+Use Task tool to launch each stream:
+```yaml
+Task:
+  description: "Issue #{issue} Stream {X}"
+  subagent_type: "{agent_type}"
+  prompt: |
+    Working in branch: epic/$ARGUMENTS
+    Issue: #{issue} - {title}
+    Stream: {stream_name}
+
+    Your scope:
+    - Files: {file_patterns}
+    - Work: {stream_description}
+
+    Read full requirements from:
+    - .claude/epics/$ARGUMENTS/{task_file}
+    - .claude/epics/$ARGUMENTS/{issue}-analysis.md
+
+    Follow coordination rules in /rules/agent-coordination.md
+
+    Commit frequently with message format:
+    "Issue #{issue}: {specific change}"
+
+    Update progress in:
+    .claude/epics/$ARGUMENTS/updates/{issue}/stream-{X}.md
+```
+
+### 5. Track Active Agents
+
+Create/update `.claude/epics/$ARGUMENTS/execution-status.md`:
+
+```markdown
+---
+started: {datetime}
+branch: epic/$ARGUMENTS
+---
+
+# Execution Status
+
+## Active Agents
+- Agent-1: Issue #1234 Stream A (Database) - Started {time}
+- Agent-2: Issue #1234 Stream B (API) - Started {time}
+- Agent-3: Issue #1235 Stream A (UI) - Started {time}
+
+## Queued Issues
+- Issue #1236 - Waiting for #1234
+- Issue #1237 - Waiting for #1235
+
+## Completed
+- {None yet}
+```
+
+### 6. Monitor and Coordinate
+
+Set up monitoring:
+```bash
+echo "
+Agents launched successfully!
+
+Monitor progress:
+  /pm:epic-status $ARGUMENTS
+
+View branch changes:
+  git status
+
+Stop all agents:
+  /pm:epic-stop $ARGUMENTS
+
+Merge when complete:
+  /pm:epic-merge $ARGUMENTS
+"
+```
+
+### 7. Handle Dependencies
+
+As agents complete streams:
+- Check if any blocked issues are now ready
+- Launch new agents for newly-ready work
+- Update execution-status.md
+
+## Output Format
+
+```
+🚀 Epic Execution Started: $ARGUMENTS

+  Issue: #{issue}
+  Stream: {stream}
+  Error: {reason}
+
+Continue with other agents? (yes/no)
+```
+
+If uncommitted changes are found:
+```
+❌ You have uncommitted changes. Please commit or stash them before starting an epic.
+
+To commit changes:
+  git add .
+  git commit -m "Your commit message"
+
+To stash changes:
+  git stash push -m "Work in progress"
+  # (Later restore with: git stash pop)
+```
+
+If branch creation fails:
+```
+❌ Cannot create branch
+  {git error message}
+
+Try: git branch -d epic/$ARGUMENTS
+Or: Check existing branches with: git branch -a

+
+Follow `/rules/github-operations.md` to ensure we're not syncing to the CCPM template:
+
+```bash
+# Check if remote origin is the CCPM template repository
+remote_url=$(git remote get-url origin 2>/dev/null || echo "")

+  echo ""
+  echo "Current remote: $remote_url"
+  exit 1
+fi
+```
+
+### 1. Create Epic Issue
+
+Strip frontmatter and prepare GitHub issue body:
+```bash
+# Extract content without frontmatter
+sed '1,/^---$/d; 1,/^---$/d' .claude/epics/$ARGUMENTS/epic.md > /tmp/epic-body-raw.md
+
+# Remove "## Tasks Created" section and replace with Stats
+awk '

+    in_tasks=1
+    next
+  }
+  /^## / && in_tasks {

+# Determine epic type (feature vs bug) from content
+if grep -qi "bug\|fix\|issue\|problem\|error" /tmp/epic-body.md; then
+  epic_type="bug"
+else
+  epic_type="feature"
+fi
+
+# Create epic issue with labels
+epic_number=$(gh issue create \
+  --title "Epic: $ARGUMENTS" \
+  --body-file /tmp/epic-body.md \
+  --label "epic,epic:$ARGUMENTS,$epic_type" \
+  --json number -q .number)
+```
+
+Store the returned issue number for epic frontmatter update.
+
+### 2. Create Task Sub-Issues
+
+Check if gh-sub-issue is available:
+```bash
+if gh extension list | grep -q "yahsan2/gh-sub-issue"; then
+  use_subissues=true
+else
+  use_subissues=false
+  echo "⚠️ gh-sub-issue not installed. Using fallback mode."
+fi
+```
+
+Count task files to determine strategy:
+```bash
+task_count=$(ls .claude/epics/$ARGUMENTS/[0-9][0-9][0-9].md 2>/dev/null | wc -l)
+```
+
+### For Small Batches (< 5 tasks): Sequential Creation
+
+```bash
+if [ "$task_count" -lt 5 ]; then
+  # Create sequentially for small batches
+  for task_file in .claude/epics/$ARGUMENTS/[0-9][0-9][0-9].md; do
+    [ -f "$task_file" ] || continue
+
+    # Extract task name from frontmatter
+    task_name=$(grep '^name:' "$task_file" | sed 's/^name: *//')
+
+    # Strip frontmatter from task content
+    sed '1,/^---$/d; 1,/^---$/d' "$task_file" > /tmp/task-body.md
+
+    # Create sub-issue with labels
+    if [ "$use_subissues" = true ]; then
+      task_number=$(gh sub-issue create \
+        --parent "$epic_number" \
+        --title "$task_name" \
+        --body-file /tmp/task-body.md \
+        --label "task,epic:$ARGUMENTS" \
+        --json number -q .number)
+    else
+      task_number=$(gh issue create \
+        --title "$task_name" \
+        --body-file /tmp/task-body.md \
+        --label "task,epic:$ARGUMENTS" \
+        --json number -q .number)
+    fi
+
+    # Record mapping for renaming
+    echo "$task_file:$task_number" >> /tmp/task-mapping.txt
+  done
+
+  # After creating all issues, update references and rename files
+  # This follows the same process as step 3 below
+fi
+```
+
+### For Larger Batches: Parallel Creation
+
+```bash
+if [ "$task_count" -ge 5 ]; then
+  echo "Creating $task_count sub-issues in parallel..."
+
+  # Check if gh-sub-issue is available for parallel agents
+  if gh extension list | grep -q "yahsan2/gh-sub-issue"; then
+    subissue_cmd="gh sub-issue create --parent $epic_number"
+  else
+    subissue_cmd="gh issue create"
+  fi
+
+  # Batch tasks for parallel processing
+  # Spawn agents to create sub-issues in parallel with proper labels
+  # Each agent must use: --label "task,epic:$ARGUMENTS"
+fi
+```
+
+Use Task tool for parallel creation:
+```yaml
+Task:
+  description: "Create GitHub sub-issues batch {X}"
+  subagent_type: "general-purpose"
+  prompt: |
+    Create GitHub sub-issues for tasks in epic $ARGUMENTS
+    Parent epic issue: #$epic_number
+
+    Tasks to process:
+    - {list of 3-4 task files}
+
+    For each task file:
+    1. Extract task name from frontmatter
+    2. Strip frontmatter using: sed '1,/^---$/d; 1,/^---$/d'
+    3. Create sub-issue using:
+       - If gh-sub-issue available:
+         gh sub-issue create --parent $epic_number --title "$task_name" \
+           --body-file /tmp/task-body.md --label "task,epic:$ARGUMENTS"
+       - Otherwise:
+         gh issue create --title "$task_name" --body-file /tmp/task-body.md \
+           --label "task,epic:$ARGUMENTS"
+    4. Record: task_file:issue_number
+
+    IMPORTANT: Always include --label parameter with "task,epic:$ARGUMENTS"
+
+    Return mapping of files to issue numbers.
+```
+
+Consolidate results from parallel agents:
+```bash
+# Collect all mappings from agents
+cat /tmp/batch-*/mapping.txt >> /tmp/task-mapping.txt
+
+# IMPORTANT: After consolidation, follow step 3 to:
+# 1. Build old->new ID mapping
+# 2. Update all task references (depends_on, conflicts_with)
+# 3. Rename files with proper frontmatter updates
+```
+
+### 3. Rename Task Files and Update References
+
+First, build a mapping of old numbers to new issue IDs:
+```bash
+# Create mapping from old task numbers (001, 002, etc.) to new issue IDs
+> /tmp/id-mapping.txt
+while IFS=: read -r task_file task_number; do
+  # Extract old number from filename (e.g., 001 from 001.md)
+  old_num=$(basename "$task_file" .md)
+  echo "$old_num:$task_number" >> /tmp/id-mapping.txt
+done < /tmp/task-mapping.txt
+```
+
+Then rename files and update all references:
+```bash
+# Process each task file
+while IFS=: read -r task_file task_number; do
+  new_name="$(dirname "$task_file")/${task_number}.md"
+
+  # Read the file content
+  content=$(cat "$task_file")
+
+  # Update depends_on and conflicts_with references
+  while IFS=: read -r old_num new_num; do
+    # Update arrays like [001, 002] to use new issue numbers
+    content=$(echo "$content" | sed "s/\b$old_num\b/$new_num/g")
+  done < /tmp/id-mapping.txt
+
+  # Write updated content to new file
+  echo "$content" > "$new_name"
+
+  # Remove old file if different from new
+  [ "$task_file" != "$new_name" ] && rm "$task_file"
+
+  # Update github field in frontmatter
+  # Add the GitHub URL to the frontmatter
+  repo=$(gh repo view --json nameWithOwner -q .nameWithOwner)
+  github_url="https://github.com/$repo/issues/$task_number"
+
+  # Update frontmatter with GitHub URL and current timestamp
+  current_date=$(date -u +"%Y-%m-%dT%H:%M:%SZ")
+
+  # Use sed to update the github and updated fields
+  sed -i.bak "/^github:/c\github: $github_url" "$new_name"
+  sed -i.bak "/^updated:/c\updated: $current_date" "$new_name"
+  rm "${new_name}.bak"
+done < /tmp/task-mapping.txt
+```
+
+### 4. Update Epic with Task List (Fallback Only)
+
+If NOT using gh-sub-issue, add task list to epic:
+
+```bash
+if [ "$use_subissues" = false ]; then
+  # Get current epic body
+  gh issue view {epic_number} --json body -q .body > /tmp/epic-body.md
+
+  # Append task list
+  cat >> /tmp/epic-body.md << 'EOF'
+
+  ## Tasks
+  - [ ] #{task1_number} {task1_name}
+  - [ ] #{task2_number} {task2_name}
+  - [ ] #{task3_number} {task3_name}
+  EOF
+
+  # Update epic issue
+  gh issue edit {epic_number} --body-file /tmp/epic-body.md
+fi
+```
+
+With gh-sub-issue, this is automatic!
+
+### 5. Update Epic File
+
+Update the epic file with GitHub URL, timestamp, and real task IDs:
+
+#### 5a. Update Frontmatter
+```bash
+# Get repo info
+repo=$(gh repo view --json nameWithOwner -q .nameWithOwner)
+epic_url="https://github.com/$repo/issues/$epic_number"
+current_date=$(date -u +"%Y-%m-%dT%H:%M:%SZ")
+
+# Update epic frontmatter
+sed -i.bak "/^github:/c\github: $epic_url" .claude/epics/$ARGUMENTS/epic.md
+sed -i.bak "/^updated:/c\updated: $current_date" .claude/epics/$ARGUMENTS/epic.md
+rm .claude/epics/$ARGUMENTS/epic.md.bak
+```
+
+#### 5b. Update Tasks Created Section
+```bash
+# Create a temporary file with the updated Tasks Created section
+cat > /tmp/tasks-section.md << 'EOF'
+## Tasks Created
+EOF
+
+# Add each task with its real issue number
+for task_file in .claude/epics/$ARGUMENTS/[0-9]*.md; do
+  [ -f "$task_file" ] || continue
+
+  # Get issue number (filename without .md)
+  issue_num=$(basename "$task_file" .md)
+
+  # Get task name from frontmatter
+  task_name=$(grep '^name:' "$task_file" | sed 's/^name: *//')
+
+  # Get parallel status
+  parallel=$(grep '^parallel:' "$task_file" | sed 's/^parallel: *//')
+
+  # Add to tasks section
+  echo "- [ ] #${issue_num} - ${task_name} (parallel: ${parallel})" >> /tmp/tasks-section.md
+done
+
+# Add summary statistics
+total_count=$(ls .claude/epics/$ARGUMENTS/[0-9]*.md 2>/dev/null | wc -l)
+parallel_count=$(grep -l '^parallel: true' .claude/epics/$ARGUMENTS/[0-9]*.md 2>/dev/null | wc -l)
+sequential_count=$((total_count - parallel_count))
+
+cat >> /tmp/tasks-section.md << EOF
+
+Total tasks: ${total_count}
+Parallel tasks: ${parallel_count}
+Sequential tasks: ${sequential_count}
+EOF
+
+# Replace the Tasks Created section in epic.md
+# First, create a backup
+cp .claude/epics/$ARGUMENTS/epic.md .claude/epics/$ARGUMENTS/epic.md.backup
+
+# Use awk to replace the section
+awk '
+  /^## Tasks Created/ {
+    skip=1
+    while ((getline line < "/tmp/tasks-section.md") > 0) print line
+    close("/tmp/tasks-section.md")
+  }
+  /^## / && !/^## Tasks Created/ { skip=0 }
+  !skip && !/^## Tasks Created/ { print }
+' .claude/epics/$ARGUMENTS/epic.md.backup > .claude/epics/$ARGUMENTS/epic.md
+
+# Clean up
+rm .claude/epics/$ARGUMENTS/epic.md.backup
+rm /tmp/tasks-section.md
+```
+
+### 6. Create Mapping File
+
+Create `.claude/epics/$ARGUMENTS/github-mapping.md`:
+```bash
+# Create mapping file
+cat > .claude/epics/$ARGUMENTS/github-mapping.md << EOF
+# GitHub Issue Mapping
+
+Epic: #${epic_number} - https://github.com/${repo}/issues/${epic_number}
+
+Tasks:
+EOF
+
+# Add each task mapping
+for task_file in .claude/epics/$ARGUMENTS/[0-9]*.md; do
+  [ -f "$task_file" ] || continue
+

+  task_name=$(grep '^name:' "$task_file" | sed 's/^name: *//')
+
+  echo "- #${issue_num}: ${task_name} - https://github.com/${repo}/issues/${issue_num}" >> .claude/epics/$ARGUMENTS/github-mapping.md

+echo "Synced: $(date -u +"%Y-%m-%dT%H:%M:%SZ")" >> .claude/epics/$ARGUMENTS/github-mapping.md
+```
+
+### 7. Create Worktree
+
+Follow `/rules/worktree-operations.md` to create development worktree:
+
+```bash
+# Ensure main is current
+git checkout main
+git pull origin main
+
+# Create worktree for epic
+git worktree add ../epic-$ARGUMENTS -b epic/$ARGUMENTS
+
+echo "✅ Created worktree: ../epic-$ARGUMENTS"
+```
+
+### 8. Output
+
+```
+✅ Synced to GitHub
+  - Epic: #{epic_number} - {epic_title}
+  - Tasks: {count} sub-issues created
+  - Labels applied: epic, task, epic:{name}
+  - Files renamed: 001.md → {issue_id}.md
+  - References updated: depends_on/conflicts_with now use issue IDs
+  - Worktree: ../epic-$ARGUMENTS
+
+Next steps:
+  - Start parallel execution: /pm:epic-start $ARGUMENTS
+  - Or work on single issue: /pm:issue-start {issue_number}
+  - View epic: https://github.com/{owner}/{repo}/issues/{epic_number}
+```
+
+## Error Handling
+
+Follow `/rules/github-operations.md` for GitHub CLI errors.
+
+If any issue creation fails:
+- Report what succeeded
+- Note what failed
+- Don't attempt rollback (partial sync is fine)
+
+## Important Notes
+
+- Trust GitHub CLI authentication
+- Don't pre-check for duplicates
+- Update frontmatter only after successful creation
+- Keep operations simple and atomic

+# Import
+
+Import existing GitHub issues into the PM system.
+
+## Usage
+```
+/pm:import [--epic <epic_name>] [--label <label>]
+```
+
+Options:
+- `--epic` - Import into specific epic
+- `--label` - Import only issues with specific label
+- No args - Import all untracked issues
+
+## Instructions
+
+### 1. Fetch GitHub Issues
+
+```bash
+# Get issues based on filters
+if [[ "$ARGUMENTS" == *"--label"* ]]; then
+  gh issue list --label "{label}" --limit 1000 --json number,title,body,state,labels,createdAt,updatedAt
+else
+  gh issue list --limit 1000 --json number,title,body,state,labels,createdAt,updatedAt
+fi
+```
+
+### 2. Identify Untracked Issues
+
+For each GitHub issue:
+- Search local files for matching github URL
+- If not found, it's untracked and needs import
+
+### 3. Categorize Issues
+
+Based on labels:
+- Issues with "epic" label → Create epic structure
+- Issues with "task" label → Create task in appropriate epic
+- Issues with "epic:{name}" label → Assign to that epic
+- No PM labels → Ask user or create in "imported" epic
+
+### 4. Create Local Structure
+
+For each issue to import:
+
+**If Epic:**
+```bash
+mkdir -p .claude/epics/{epic_name}
+# Create epic.md with GitHub content and frontmatter
+```
+
+**If Task:**
+```bash
+# Find next available number (001.md, 002.md, etc.)
+# Create task file with GitHub content
+```
+
+Set frontmatter:
+```yaml
+name: {issue_title}
+status: {open|closed based on GitHub}
+created: {GitHub createdAt}
+updated: {GitHub updatedAt}
+github: https://github.com/{org}/{repo}/issues/{number}
+imported: true
+```
+
+### 5. Output
+
+```
+📥 Import Complete
+
+Imported:
+  Epics: {count}
+  Tasks: {count}
+  
+Created structure:
+  {epic_1}/
+    - {count} tasks
+  {epic_2}/
+    - {count} tasks
+    
+Skipped (already tracked): {count}
+
+Next steps:
+  Run /pm:status to see imported work
+  Run /pm:sync to ensure full synchronization
+```
+
+## Important Notes
+
+Preserve all GitHub metadata in frontmatter.
+Mark imported files with `imported: true` flag.
+Don't overwrite existing local files.

+# Issue Analyze
+
+Analyze an issue to identify parallel work streams for maximum efficiency.
+
+## Usage
+```
+/pm:issue-analyze <issue_number>
+```
+
+## Quick Check
+
+1. **Find local task file:**
+   - First check if `.claude/epics/*/$ARGUMENTS.md` exists (new naming convention)
+   - If not found, search for file containing `github:.*issues/$ARGUMENTS` in frontmatter (old naming)
+   - If not found: "❌ No local task for issue #$ARGUMENTS. Run: /pm:import first"
+
+2. **Check for existing analysis:**
+   ```bash
+   test -f .claude/epics/*/$ARGUMENTS-analysis.md && echo "⚠️ Analysis already exists. Overwrite? (yes/no)"
+   ```
+
+## Instructions
+
+### 1. Read Issue Context
+
+Get issue details from GitHub:
+```bash
+gh issue view $ARGUMENTS --json title,body,labels
+```
+
+Read local task file to understand:
+- Technical requirements
+- Acceptance criteria
+- Dependencies
+- Effort estimate
+
+### 2. Identify Parallel Work Streams
+
+Analyze the issue to identify independent work that can run in parallel:
+
+**Common Patterns:**
+- **Database Layer**: Schema, migrations, models
+- **Service Layer**: Business logic, data access
+- **API Layer**: Endpoints, validation, middleware
+- **UI Layer**: Components, pages, styles
+- **Test Layer**: Unit tests, integration tests
+- **Documentation**: API docs, README updates
+
+**Key Questions:**
+- What files will be created/modified?
+- Which changes can happen independently?
+- What are the dependencies between changes?
+- Where might conflicts occur?
+
+### 3. Create Analysis File
+
+Get current datetime: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+
+Create `.claude/epics/{epic_name}/$ARGUMENTS-analysis.md`:
+
+```markdown
+---
+issue: $ARGUMENTS
+title: {issue_title}
+analyzed: {current_datetime}
+estimated_hours: {total_hours}
+parallelization_factor: {1.0-5.0}
+---
+
+# Parallel Work Analysis: Issue #$ARGUMENTS
+
+## Overview
+{Brief description of what needs to be done}
+
+## Parallel Streams
+
+### Stream A: {Stream Name}
+**Scope**: {What this stream handles}
+**Files**:
+- {file_pattern_1}
+- {file_pattern_2}
+**Agent Type**: {backend|frontend|fullstack|database}-specialist
+**Can Start**: immediately
+**Estimated Hours**: {hours}
+**Dependencies**: none
+
+### Stream B: {Stream Name}
+**Scope**: {What this stream handles}
+**Files**:
+- {file_pattern_1}
+- {file_pattern_2}
+**Agent Type**: {agent_type}
+**Can Start**: immediately
+**Estimated Hours**: {hours}
+**Dependencies**: none
+
+### Stream C: {Stream Name}
+**Scope**: {What this stream handles}
+**Files**:
+- {file_pattern_1}
+**Agent Type**: {agent_type}
+**Can Start**: after Stream A completes
+**Estimated Hours**: {hours}
+**Dependencies**: Stream A
+
+## Coordination Points
+
+### Shared Files
+{List any files multiple streams need to modify}:
+- `src/types/index.ts` - Streams A & B (coordinate type updates)
+- `package.json` - Stream B (add dependencies)
+
+### Sequential Requirements
+{List what must happen in order}:
+1. Database schema before API endpoints
+2. API types before UI components
+3. Core logic before tests
+
+## Conflict Risk Assessment
+- **Low Risk**: Streams work on different directories
+- **Medium Risk**: Some shared type files, manageable with coordination
+- **High Risk**: Multiple streams modifying same core files
+
+## Parallelization Strategy
+
+**Recommended Approach**: {sequential|parallel|hybrid}
+
+{If parallel}: Launch Streams A, B simultaneously. Start C when A completes.
+{If sequential}: Complete Stream A, then B, then C.
+{If hybrid}: Start A & B together, C depends on A, D depends on B & C.
+
+## Expected Timeline
+
+With parallel execution:
+- Wall time: {max_stream_hours} hours
+- Total work: {sum_all_hours} hours
+- Efficiency gain: {percentage}%
+
+Without parallel execution:
+- Wall time: {sum_all_hours} hours
+
+## Notes
+{Any special considerations, warnings, or recommendations}
+```
+
+### 4. Validate Analysis
+
+Ensure:
+- All major work is covered by streams
+- File patterns don't unnecessarily overlap
+- Dependencies are logical
+- Agent types match the work type
+- Time estimates are reasonable
+
+### 5. Output
+
+```
+✅ Analysis complete for issue #$ARGUMENTS
+
+Identified {count} parallel work streams:
+  Stream A: {name} ({hours}h)
+  Stream B: {name} ({hours}h)
+  Stream C: {name} ({hours}h)
+  
+Parallelization potential: {factor}x speedup
+  Sequential time: {total}h
+  Parallel time: {reduced}h
+
+Files at risk of conflict:
+  {list shared files if any}
+
+Next: Start work with /pm:issue-start $ARGUMENTS
+```
+
+## Important Notes
+
+- Analysis is local only - not synced to GitHub
+- Focus on practical parallelization, not theoretical maximum
+- Consider agent expertise when assigning streams
+- Account for coordination overhead in estimates
+- Prefer clear separation over maximum parallelization

+Begin work on a GitHub issue with parallel agents based on work stream analysis.
+
+## Usage
+```
+/pm:issue-start <issue_number>
+```
+
+## Quick Check
+
+1. **Get issue details:**
+   ```bash
+   gh issue view $ARGUMENTS --json state,title,labels,body
+   ```
+   If it fails: "❌ Cannot access issue #$ARGUMENTS. Check number or run: gh auth login"
+
+2. **Find local task file:**
+   - First check if `.claude/epics/*/$ARGUMENTS.md` exists (new naming)
+   - If not found, search for file containing `github:.*issues/$ARGUMENTS` in frontmatter (old naming)
+   - If not found: "❌ No local task for issue #$ARGUMENTS. This issue may have been created outside the PM system."
+
+3. **Check for analysis:**
+   ```bash
+   test -f .claude/epics/*/$ARGUMENTS-analysis.md || echo "❌ No analysis found for issue #$ARGUMENTS
+   
+   Run: /pm:issue-analyze $ARGUMENTS first
+   Or: /pm:issue-start $ARGUMENTS --analyze to do both"
+   ```
+   If no analysis exists and no --analyze flag, stop execution.
+
+## Instructions
+
+### 1. Ensure Worktree Exists
+
+Check if epic worktree exists:
+```bash
+# Find epic name from task file
+epic_name={extracted_from_path}
+
+# Check worktree
+if ! git worktree list | grep -q "epic-$epic_name"; then
+  echo "❌ No worktree for epic. Run: /pm:epic-start $epic_name"
+  exit 1
+fi
+```
+
+### 2. Read Analysis
+
+Read `.claude/epics/{epic_name}/$ARGUMENTS-analysis.md`:
+- Parse parallel streams
+- Identify which can start immediately
+- Note dependencies between streams
+
+### 3. Setup Progress Tracking
+
+Get current datetime: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+
+Create workspace structure:
+```bash
+mkdir -p .claude/epics/{epic_name}/updates/$ARGUMENTS
+```
+
+Update task file frontmatter `updated` field with current datetime.
+
+### 4. Launch Parallel Agents
+
+For each stream that can start immediately:
+
+Create `.claude/epics/{epic_name}/updates/$ARGUMENTS/stream-{X}.md`:
+```markdown
+---
+issue: $ARGUMENTS
+stream: {stream_name}
+agent: {agent_type}
+started: {current_datetime}

+---
+
+# Stream {X}: {stream_name}

+# Issue Sync
+
+Push local updates as GitHub issue comments for transparent audit trail.
+
+## Usage
+```
+/pm:issue-sync <issue_number>
+```
+
+## Required Rules
+
+**IMPORTANT:** Before executing this command, read and follow:
+- `.claude/rules/datetime.md` - For getting real current date/time
+
+## Preflight Checklist
+
+Before proceeding, complete these validation steps.
+Do not bother the user with preflight checks progress ("I'm not going to ..."). Just do them and move on.
+
+0. **Repository Protection Check:**
+   Follow `/rules/github-operations.md` - check remote origin:
+   ```bash
+   remote_url=$(git remote get-url origin 2>/dev/null || echo "")
+   if [[ "$remote_url" == *"automazeio/ccpm"* ]]; then
+     echo "❌ ERROR: Cannot sync to CCPM template repository!"
+     echo "Update your remote: git remote set-url origin https://github.com/YOUR_USERNAME/YOUR_REPO.git"
+     exit 1
+   fi
+   ```
+
+1. **GitHub Authentication:**
+   - Run: `gh auth status`
+   - If not authenticated, tell user: "❌ GitHub CLI not authenticated. Run: gh auth login"
+
+2. **Issue Validation:**
+   - Run: `gh issue view $ARGUMENTS --json state`
+   - If issue doesn't exist, tell user: "❌ Issue #$ARGUMENTS not found"
+   - If issue is closed and completion < 100%, warn: "⚠️ Issue is closed but work incomplete"
+
+3. **Local Updates Check:**
+   - Check if `.claude/epics/*/updates/$ARGUMENTS/` directory exists
+   - If not found, tell user: "❌ No local updates found for issue #$ARGUMENTS. Run: /pm:issue-start $ARGUMENTS"
+   - Check if progress.md exists
+   - If not, tell user: "❌ No progress tracking found. Initialize with: /pm:issue-start $ARGUMENTS"
+
+4. **Check Last Sync:**
+   - Read `last_sync` from progress.md frontmatter
+   - If synced recently (< 5 minutes), ask: "⚠️ Recently synced. Force sync anyway? (yes/no)"
+   - Calculate what's new since last sync
+
+5. **Verify Changes:**
+   - Check if there are actual updates to sync
+   - If no changes, tell user: "ℹ️ No new updates to sync since {last_sync}"
+   - Exit gracefully if nothing to sync
+
+## Instructions
+
+You are synchronizing local development progress to GitHub as issue comments for: **Issue #$ARGUMENTS**
+
+### 1. Gather Local Updates
+Collect all local updates for the issue:
+- Read from `.claude/epics/{epic_name}/updates/$ARGUMENTS/`
+- Check for new content in:
+  - `progress.md` - Development progress
+  - `notes.md` - Technical notes and decisions
+  - `commits.md` - Recent commits and changes
+  - Any other update files
+
+### 2. Update Progress Tracking Frontmatter
+Get current datetime: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+
+Update the progress.md file frontmatter:
+```yaml
+---
+issue: $ARGUMENTS
+started: [preserve existing date]
+last_sync: [Use REAL datetime from command above]
+completion: [calculated percentage 0-100%]
+---
+```
+
+### 3. Determine What's New
+Compare against previous sync to identify new content:
+- Look for sync timestamp markers
+- Identify new sections or updates
+- Gather only incremental changes since last sync
+
+### 4. Format Update Comment
+Create comprehensive update comment:
+
+```markdown
+## 🔄 Progress Update - {current_date}
+
+### ✅ Completed Work
+{list_completed_items}
+
+### 🔄 In Progress
+{current_work_items}
+
+### 📝 Technical Notes
+{key_technical_decisions}
+
+### 📊 Acceptance Criteria Status
+- ✅ {completed_criterion}
+- 🔄 {in_progress_criterion}
+- ⏸️ {blocked_criterion}
+- □ {pending_criterion}
+
+### 🚀 Next Steps
+{planned_next_actions}
+
+### ⚠️ Blockers
+{any_current_blockers}
+
+### 💻 Recent Commits
+{commit_summaries}
+
+---
+*Progress: {completion}% | Synced from local updates at {timestamp}*
+```
+
+### 5. Post to GitHub
+Use GitHub CLI to add comment:
+```bash
+gh issue comment #$ARGUMENTS --body-file {temp_comment_file}
+```
+
+### 6. Update Local Task File
+Get current datetime: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+
+Update the task file frontmatter with sync information:
+```yaml
+---
+name: [Task Title]
+status: open
+created: [preserve existing date]
+updated: [Use REAL datetime from command above]
+github: https://github.com/{org}/{repo}/issues/$ARGUMENTS
+---
+```
+
+### 7. Handle Completion
+If task is complete, update all relevant frontmatter:
+
+**Task file frontmatter**:
+```yaml
+---
+name: [Task Title]
+status: closed
+created: [existing date]
+updated: [current date/time]
+github: https://github.com/{org}/{repo}/issues/$ARGUMENTS
+---
+```
+
+**Progress file frontmatter**:
+```yaml
+---
+issue: $ARGUMENTS
+started: [existing date]
+last_sync: [current date/time]
+completion: 100%
+---
+```
+
+**Epic progress update**: Recalculate epic progress based on completed tasks and update epic frontmatter:
+```yaml
+---
+name: [Epic Name]
+status: in-progress
+created: [existing date]
+progress: [calculated percentage based on completed tasks]%
+prd: [existing path]
+github: [existing URL]
+---
+```
+
+### 8. Completion Comment
+If task is complete:
+```markdown
+## ✅ Task Completed - {current_date}
+
+### 🎯 All Acceptance Criteria Met
+- ✅ {criterion_1}
+- ✅ {criterion_2}
+- ✅ {criterion_3}
+
+### 📦 Deliverables

+- Manual testing: ✅ Complete
+
+### 📚 Documentation
+- Code documentation: ✅ Updated
+- README updates: ✅ Complete
+
+This task is ready for review and can be closed.
+
+---
+*Task completed: 100% | Synced at {timestamp}*
+```
+
+### 9. Output Summary
+```
+☁️ Synced updates to GitHub Issue #$ARGUMENTS
+
+📝 Update summary:
+   Progress items: {progress_count}
+   Technical notes: {notes_count}
+   Commits referenced: {commit_count}
+
+📊 Current status:
+   Task completion: {task_completion}%
+   Epic progress: {epic_progress}%
+   Completed criteria: {completed}/{total}
+
+🔗 View update: gh issue view #$ARGUMENTS --comments
+```
+
+### 10. Frontmatter Maintenance
+- Always update task file frontmatter with current timestamp
+- Track completion percentages in progress files
+- Update epic progress when tasks complete
+- Maintain sync timestamps for audit trail
+
+### 11. Incremental Sync Detection
+
+**Prevent Duplicate Comments:**
+1. Add sync markers to local files after each sync:
+   ```markdown
+   <!-- SYNCED: 2024-01-15T10:30:00Z -->
+   ```
+2. Only sync content added after the last marker
+3. If no new content, skip sync with message: "No updates since last sync"
+
+### 12. Comment Size Management
+
+**Handle GitHub's Comment Limits:**
+- Max comment size: 65,536 characters
+- If update exceeds limit:
+  1. Split into multiple comments
+  2. Or summarize with link to full details
+  3. Warn user: "⚠️ Update truncated due to size. Full details in local files."
+
+### 13. Error Handling
+
+**Common Issues and Recovery:**
+
+1. **Network Error:**
+   - Message: "❌ Failed to post comment: network error"
+   - Solution: "Check internet connection and retry"
+   - Keep local updates intact for retry
+
+2. **Rate Limit:**
+   - Message: "❌ GitHub rate limit exceeded"
+   - Solution: "Wait {minutes} minutes or use different token"
+   - Save comment locally for later sync
+
+3. **Permission Denied:**
+   - Message: "❌ Cannot comment on issue (permission denied)"
+   - Solution: "Check repository access permissions"
+
+4. **Issue Locked:**
+   - Message: "⚠️ Issue is locked for comments"
+   - Solution: "Contact repository admin to unlock"
+
+### 14. Epic Progress Calculation
+
+When updating epic progress:
+1. Count total tasks in epic directory
+2. Count tasks with `status: closed` in frontmatter
+3. Calculate: `progress = (closed_tasks / total_tasks) * 100`
+4. Round to nearest integer
+5. Update epic frontmatter only if percentage changed
+
+### 15. Post-Sync Validation
+
+After successful sync:
+- [ ] Verify comment posted on GitHub
+- [ ] Confirm frontmatter updated with sync timestamp
+- [ ] Check epic progress updated if task completed
+- [ ] Validate no data corruption in local files
+
+This creates a transparent audit trail of development progress that stakeholders can follow in real-time for Issue #$ARGUMENTS, while maintaining accurate frontmatter across all project files.

+# PRD New
+
+Launch brainstorming for new product requirement document.
+
+## Usage
+```
+/pm:prd-new <feature_name>
+```
+
+## Required Rules
+
+**IMPORTANT:** Before executing this command, read and follow:
+- `.claude/rules/datetime.md` - For getting real current date/time
+
+## Preflight Checklist
+
+Before proceeding, complete these validation steps.
+Do not bother the user with preflight checks progress ("I'm not going to ..."). Just do them and move on.
+
+### Input Validation
+1. **Validate feature name format:**
+   - Must contain only lowercase letters, numbers, and hyphens
+   - Must start with a letter
+   - No spaces or special characters allowed
+   - If invalid, tell user: "❌ Feature name must be kebab-case (lowercase letters, numbers, hyphens only). Examples: user-auth, payment-v2, notification-system"
+
+2. **Check for existing PRD:**
+   - Check if `.claude/prds/$ARGUMENTS.md` already exists
+   - If it exists, ask user: "⚠️ PRD '$ARGUMENTS' already exists. Do you want to overwrite it? (yes/no)"
+   - Only proceed with explicit 'yes' confirmation
+   - If user says no, suggest: "Use a different name or run: /pm:prd-parse $ARGUMENTS to create an epic from the existing PRD"
+
+3. **Verify directory structure:**
+   - Check if `.claude/prds/` directory exists
+   - If not, create it first
+   - If unable to create, tell user: "❌ Cannot create PRD directory. Please manually create: .claude/prds/"
+
+## Instructions
+
+You are a product manager creating a comprehensive Product Requirements Document (PRD) for: **$ARGUMENTS**
+
+Follow this structured approach:
+
+### 1. Discovery & Context
+- Ask clarifying questions about the feature/product "$ARGUMENTS"
+- Understand the problem being solved
+- Identify target users and use cases
+- Gather constraints and requirements
+
+### 2. PRD Structure
+Create a comprehensive PRD with these sections:
+
+#### Executive Summary
+- Brief overview and value proposition
+
+#### Problem Statement
+- What problem are we solving?
+- Why is this important now?
+
+#### User Stories
+- Primary user personas
+- Detailed user journeys
+- Pain points being addressed
+
+#### Requirements
+**Functional Requirements**
+- Core features and capabilities
+- User interactions and flows
+
+**Non-Functional Requirements**
+- Performance expectations
+- Security considerations
+- Scalability needs
+
+#### Success Criteria
+- Measurable outcomes
+- Key metrics and KPIs
+
+#### Constraints & Assumptions
+- Technical limitations
+- Timeline constraints
+- Resource limitations
+
+#### Out of Scope
+- What we're explicitly NOT building
+
+#### Dependencies
+- External dependencies
+- Internal team dependencies
+
+### 3. File Format with Frontmatter
+Save the completed PRD to: `.claude/prds/$ARGUMENTS.md` with this exact structure:
+
+```markdown
+---
+name: $ARGUMENTS
+description: [Brief one-line description of the PRD]
+status: backlog
+created: [Current ISO date/time]
+---
+
+# PRD: $ARGUMENTS
+
+## Executive Summary
+[Content...]
+
+## Problem Statement
+[Content...]
+
+[Continue with all sections...]
+```
+
+### 4. Frontmatter Guidelines
+- **name**: Use the exact feature name (same as $ARGUMENTS)
+- **description**: Write a concise one-line summary of what this PRD covers
+- **status**: Always start with "backlog" for new PRDs
+- **created**: Get REAL current datetime by running: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+  - Never use placeholder text
+  - Must be actual system time in ISO 8601 format
+
+### 5. Quality Checks
+
+Before saving the PRD, verify:
+- [ ] All sections are complete (no placeholder text)
+- [ ] User stories include acceptance criteria
+- [ ] Success criteria are measurable
+- [ ] Dependencies are clearly identified
+- [ ] Out of scope items are explicitly listed
+
+### 6. Post-Creation
+
+After successfully creating the PRD:
+1. Confirm: "✅ PRD created: .claude/prds/$ARGUMENTS.md"
+2. Show brief summary of what was captured
+3. Suggest next step: "Ready to create implementation epic? Run: /pm:prd-parse $ARGUMENTS"
+
+## Error Recovery
+
+If any step fails:
+- Clearly explain what went wrong
+- Provide specific steps to fix the issue
+- Never leave partial or corrupted files
+
+Conduct a thorough brainstorming session before writing the PRD. Ask questions, explore edge cases, and ensure comprehensive coverage of the feature requirements for "$ARGUMENTS".

+- [ ] Category 1: Description
+- [ ] Category 2: Description
+- [ ] etc.
+
+## Dependencies
+- External service dependencies
+- Internal team dependencies
+- Prerequisite work
+
+## Success Criteria (Technical)
+- Performance benchmarks
+- Quality gates
+- Acceptance criteria
+
+## Estimated Effort
+- Overall timeline estimate
+- Resource requirements
+- Critical path items
+```
+
+### 4. Frontmatter Guidelines
+- **name**: Use the exact feature name (same as $ARGUMENTS)
+- **status**: Always start with "backlog" for new epics
+- **created**: Get REAL current datetime by running: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+- **progress**: Always start with "0%" for new epics
+- **prd**: Reference the source PRD file path
+- **github**: Leave placeholder text - will be updated during sync
+
+### 5. Output Location
+Create the directory structure if it doesn't exist:
+- `.claude/epics/$ARGUMENTS/` (directory)
+- `.claude/epics/$ARGUMENTS/epic.md` (epic file)
+
+### 6. Quality Validation
+
+Before saving the epic, verify:
+- [ ] All PRD requirements are addressed in the technical approach
+- [ ] Task breakdown categories cover all implementation areas
+- [ ] Dependencies are technically accurate
+- [ ] Effort estimates are realistic
+- [ ] Architecture decisions are justified
+
+### 7. Post-Creation
+
+After successfully creating the epic:
+1. Confirm: "✅ Epic created: .claude/epics/$ARGUMENTS/epic.md"
+2. Show summary of:
+   - Number of task categories identified
+   - Key architecture decisions
+   - Estimated effort
+3. Suggest next step: "Ready to break down into tasks? Run: /pm:epic-decompose $ARGUMENTS"
+
+## Error Recovery
+
+If any step fails:
+- Clearly explain what went wrong
+- If PRD is incomplete, list specific missing sections
+- If technical approach is unclear, identify what needs clarification
+- Never create an epic with incomplete information
+
+Focus on creating a technically sound implementation plan that addresses all PRD requirements while being practical and achievable for "$ARGUMENTS".
+
+## IMPORTANT:
+- Aim for as few tasks as possible and limit the total number of tasks to 10 or less.
+- When creating the epic, identify ways to simplify and improve it. Look for ways to leverage existing functionality instead of creating more code when possible.

+# Sync
+
+Full bidirectional sync between local and GitHub.
+
+## Usage
+```
+/pm:sync [epic_name]
+```
+
+If epic_name provided, sync only that epic. Otherwise sync all.
+
+## Instructions
+
+### 1. Pull from GitHub
+
+Get current state of all issues:
+```bash
+# Get all epic and task issues
+gh issue list --label "epic" --limit 1000 --json number,title,state,body,labels,updatedAt
+gh issue list --label "task" --limit 1000 --json number,title,state,body,labels,updatedAt
+```
+
+### 2. Update Local from GitHub
+
+For each GitHub issue:
+- Find corresponding local file by issue number
+- Compare states:
+  - If GitHub state newer (updatedAt > local updated), update local
+  - If GitHub closed but local open, close local
+  - If GitHub reopened but local closed, reopen local
+- Update frontmatter to match GitHub state
+
+### 3. Push Local to GitHub
+
+For each local task/epic:
+- If has GitHub URL but GitHub issue not found, it was deleted - mark local as archived
+- If no GitHub URL, create new issue (like epic-sync)
+- If local updated > GitHub updatedAt, push changes:
+  ```bash
+  gh issue edit {number} --body-file {local_file}
+  ```
+
+### 4. Handle Conflicts
+
+If both changed (local and GitHub updated since last sync):
+- Show both versions
+- Ask user: "Local and GitHub both changed. Keep: (local/github/merge)?"
+- Apply user's choice
+
+### 5. Update Sync Timestamps
+
+Update all synced files with last_sync timestamp.
+
+### 6. Output
+
+```
+🔄 Sync Complete
+
+Pulled from GitHub:
+  Updated: {count} files
+  Closed: {count} issues
+  
+Pushed to GitHub:
+  Updated: {count} issues
+  Created: {count} new issues
+  
+Conflicts resolved: {count}
+
+Status:
+  ✅ All files synced
+  {or list any sync failures}
+```
+
+## Important Notes
+
+Follow `/rules/github-operations.md` for GitHub commands.
+Follow `/rules/frontmatter-operations.md` for local updates.
+Always backup before sync in case of issues.

+# Test Reference Update
+
+Test the task reference update logic used in epic-sync.
+
+## Usage
+```
+/pm:test-reference-update
+```
+
+## Instructions
+
+### 1. Create Test Files
+
+Create test task files with references:
+```bash
+mkdir -p /tmp/test-refs
+cd /tmp/test-refs
+
+# Create task 001
+cat > 001.md << 'EOF'
+---
+name: Task One
+status: open
+depends_on: []
+parallel: true
+conflicts_with: [002, 003]
+---
+# Task One
+This is task 001.
+EOF
+
+# Create task 002
+cat > 002.md << 'EOF'
+---
+name: Task Two
+status: open
+depends_on: [001]
+parallel: false
+conflicts_with: [003]
+---
+# Task Two
+This is task 002, depends on 001.
+EOF
+
+# Create task 003
+cat > 003.md << 'EOF'
+---
+name: Task Three
+status: open
+depends_on: [001, 002]
+parallel: false
+conflicts_with: []
+---
+# Task Three
+This is task 003, depends on 001 and 002.
+EOF
+```
+
+### 2. Create Mappings
+
+Simulate the issue creation mappings:
+```bash
+# Simulate task -> issue number mapping
+cat > /tmp/task-mapping.txt << 'EOF'
+001.md:42
+002.md:43
+003.md:44
+EOF
+
+# Create old -> new ID mapping
+> /tmp/id-mapping.txt
+while IFS=: read -r task_file task_number; do
+  old_num=$(basename "$task_file" .md)
+  echo "$old_num:$task_number" >> /tmp/id-mapping.txt
+done < /tmp/task-mapping.txt
+
+echo "ID Mapping:"
+cat /tmp/id-mapping.txt
+```
+
+### 3. Update References
+
+Process each file and update references:
+```bash
+while IFS=: read -r task_file task_number; do
+  echo "Processing: $task_file -> $task_number.md"
+  
+  # Read the file content
+  content=$(cat "$task_file")
+  
+  # Update references
+  while IFS=: read -r old_num new_num; do
+    content=$(echo "$content" | sed "s/\b$old_num\b/$new_num/g")
+  done < /tmp/id-mapping.txt
+  
+  # Write to new file
+  new_name="${task_number}.md"
+  echo "$content" > "$new_name"
+  
+  echo "Updated content preview:"
+  grep -E "depends_on:|conflicts_with:" "$new_name"
+  echo "---"
+done < /tmp/task-mapping.txt
+```
+
+### 4. Verify Results
+
+Check that references were updated correctly:
+```bash
+echo "=== Final Results ==="
+for file in 42.md 43.md 44.md; do
+  echo "File: $file"
+  grep -E "name:|depends_on:|conflicts_with:" "$file"
+  echo ""
+done
+```
+
+Expected output:
+- 42.md should have conflicts_with: [43, 44]
+- 43.md should have depends_on: [42] and conflicts_with: [44]
+- 44.md should have depends_on: [42, 43]
+
+### 5. Cleanup
+
+```bash
+cd -
+rm -rf /tmp/test-refs
+rm -f /tmp/task-mapping.txt /tmp/id-mapping.txt
+echo "✅ Test complete and cleaned up"
+```

+# Prime Testing Environment
+
+This command prepares the testing environment by detecting the test framework, validating dependencies, and configuring the test-runner agent for optimal test execution.
+
+## Preflight Checklist
+
+Before proceeding, complete these validation steps.
+Do not bother the user with preflight checks progress ("I'm not going to ..."). Just do them and move on.
+
+### 1. Test Framework Detection
+
+**JavaScript/Node.js:**
+- Check package.json for test scripts: `grep -E '"test"|"spec"|"jest"|"mocha"' package.json 2>/dev/null`
+- Look for test config files: `ls -la jest.config.* mocha.opts .mocharc.* 2>/dev/null`
+- Check for test directories: `find . -type d \( -name "test" -o -name "tests" -o -name "__tests__" -o -name "spec" \) -maxdepth 3 2>/dev/null`
+
+**Python:**
+- Check for pytest: `find . -name "pytest.ini" -o -name "conftest.py" -o -name "setup.cfg" 2>/dev/null | head -5`
+- Check for unittest: `find . -path "*/test*.py" -o -path "*/test_*.py" 2>/dev/null | head -5`
+- Check requirements: `grep -E "pytest|unittest|nose" requirements.txt 2>/dev/null`
+
+**Rust:**
+- Check for Cargo tests: `grep -E '\[dev-dependencies\]' Cargo.toml 2>/dev/null`
+- Look for test modules: `find . -name "*.rs" -exec grep -l "#\[cfg(test)\]" {} \; 2>/dev/null | head -5`
+
+**Go:**
+- Check for test files: `find . -name "*_test.go" 2>/dev/null | head -5`
+- Check go.mod exists: `test -f go.mod && echo "Go module found"`
+
+**Other Languages:**
+- Ruby: Check for RSpec: `find . -name ".rspec" -o -name "spec_helper.rb" 2>/dev/null`
+- Java: Check for JUnit: `find . -name "pom.xml" -exec grep -l "junit" {} \; 2>/dev/null`
+
+### 2. Test Environment Validation
+
+If no test framework detected:
+- Tell user: "⚠️ No test framework detected. Please specify your testing setup."
+- Ask: "What test command should I use? (e.g., npm test, pytest, cargo test)"
+- Store response for future use
+
+### 3. Dependency Check
+
+**For detected framework:**
+- Node.js: Run `npm list --depth=0 2>/dev/null | grep -E "jest|mocha|chai|jasmine"`
+- Python: Run `pip list 2>/dev/null | grep -E "pytest|unittest|nose"`
+- Verify test dependencies are installed
+
+If dependencies missing:
+- Tell user: "❌ Test dependencies not installed"
+- Suggest: "Run: npm install (or pip install -r requirements.txt)"
+
+## Instructions
+
+### 1. Framework-Specific Configuration
+
+Based on detected framework, create test configuration:
+
+#### JavaScript/Node.js (Jest)
+```yaml
+framework: jest
+test_command: npm test
+test_directory: __tests__
+config_file: jest.config.js
+options:
+  - --verbose
+  - --no-coverage
+  - --runInBand
+environment:
+  NODE_ENV: test
+```
+
+#### JavaScript/Node.js (Mocha)
+```yaml
+framework: mocha
+test_command: npm test
+test_directory: test
+config_file: .mocharc.js
+options:
+  - --reporter spec
+  - --recursive
+  - --bail
+environment:
+  NODE_ENV: test
+```
+
+#### Python (Pytest)
+```yaml
+framework: pytest
+test_command: pytest
+test_directory: tests
+config_file: pytest.ini
+options:
+  - -v
+  - --tb=short
+  - --strict-markers
+environment:
+  PYTHONPATH: .
+```
+
+#### Rust
+```yaml
+framework: cargo
+test_command: cargo test
+test_directory: tests
+config_file: Cargo.toml
+options:
+  - --verbose
+  - --nocapture
+environment: {}
+```
+
+#### Go
+```yaml
+framework: go
+test_command: go test
+test_directory: .
+config_file: go.mod
+options:
+  - -v
+  - ./...
+environment: {}
+```
+
+### 2. Test Discovery
+
+Scan for test files:
+- Count total test files found
+- Identify test naming patterns used
+- Note any test utilities or helpers
+- Check for test fixtures or data
+
+```bash
+# Example for Node.js
+find . -path "*/node_modules" -prune -o -name "*.test.js" -o -name "*.spec.js" | wc -l
+```
+
+### 3. Create Test Runner Configuration
+
+Create `.claude/testing-config.md` with discovered information:
+
+```markdown
+---
+framework: {detected_framework}
+test_command: {detected_command}
+created: [Use REAL datetime from: date -u +"%Y-%m-%dT%H:%M:%SZ"]
+---
+
+# Testing Configuration
+
+## Framework
+- Type: {framework_name}
+- Version: {framework_version}
+- Config File: {config_file_path}
+
+## Test Structure
+- Test Directory: {test_dir}
+- Test Files: {count} files found
+- Naming Pattern: {pattern}
+
+## Commands
+- Run All Tests: `{full_test_command}`
+- Run Specific Test: `{specific_test_command}`
+- Run with Debugging: `{debug_command}`
+
+## Environment
+- Required ENV vars: {list}
+- Test Database: {if applicable}
+- Test Servers: {if applicable}
+
+## Test Runner Agent Configuration
+- Use verbose output for debugging
+- Run tests sequentially (no parallel)
+- Capture full stack traces
+- No mocking - use real implementations
+- Wait for each test to complete
+```
+
+### 4. Configure Test-Runner Agent
+
+Prepare agent context based on framework:
+
+```markdown
+# Test-Runner Agent Configuration
+
+## Project Testing Setup
+- Framework: {framework}
+- Test Location: {directories}
+- Total Tests: {count}
+- Last Run: Never
+
+## Execution Rules
+1. Always use the test-runner agent from `.claude/agents/test-runner.md`
+2. Run with maximum verbosity for debugging
+3. No mock services - use real implementations
+4. Execute tests sequentially - no parallel execution
+5. Capture complete output including stack traces
+6. If test fails, analyze test structure before assuming code issue
+7. Report detailed failure analysis with context
+
+## Test Command Templates
+- Full Suite: `{full_command}`
+- Single File: `{single_file_command}`
+- Pattern Match: `{pattern_command}`
+- Watch Mode: `{watch_command}` (if available)
+
+## Common Issues to Check
+- Environment variables properly set
+- Test database/services running
+- Dependencies installed
+- Proper file permissions
+- Clean test state between runs
+```
+
+### 5. Validation Steps
+
+After configuration:
+- Try running a simple test to validate setup
+- Check if test command works: `{test_command} --version` or equivalent
+- Verify test files are discoverable
+- Ensure no permission issues
+
+### 6. Output Summary
+
+```
+🧪 Testing Environment Primed
+
+🔍 Detection Results:
+  ✅ Framework: {framework_name} {version}
+  ✅ Test Files: {count} files in {directories}
+  ✅ Config: {config_file}
+  ✅ Dependencies: All installed
+
+📋 Test Structure:
+  - Pattern: {test_file_pattern}
+  - Directories: {test_directories}
+  - Utilities: {test_helpers}
+
+🤖 Agent Configuration:
+  ✅ Test-runner agent configured
+  ✅ Verbose output enabled
+  ✅ Sequential execution set
+  ✅ Real services (no mocks)
+
+⚡ Ready Commands:
+  - Run all tests: /testing:run
+  - Run specific: /testing:run {test_file}
+  - Run pattern: /testing:run {pattern}
+
+💡 Tips:
+  - Always run tests with verbose output
+  - Check test structure if tests fail
+  - Use real services, not mocks
+  - Let each test complete fully
+```
+
+### 7. Error Handling
+
+**Common Issues:**
+
+**No Framework Detected:**
+- Message: "⚠️ No test framework found"
+- Solution: "Please specify test command manually"
+- Store user's response for future use
+
+**Missing Dependencies:**
+- Message: "❌ Test framework not installed"
+- Solution: "Install dependencies first: npm install / pip install -r requirements.txt"
+
+**No Test Files:**
+- Message: "⚠️ No test files found"
+- Solution: "Create tests first or check test directory location"
+
+**Permission Issues:**
+- Message: "❌ Cannot access test files"
+- Solution: "Check file permissions"
+
+### 8. Save Configuration
+
+If successful, save configuration for future sessions:
+- Store in `.claude/testing-config.md`
+- Include all discovered settings
+- Update on subsequent runs if changes detected
+
+## Important Notes
+
+- **Always detect** rather than assume test framework
+- **Validate dependencies** before claiming ready
+- **Configure for debugging** - verbose output is critical
+- **No mocking** - use real services for accurate testing
+- **Sequential execution** - avoid parallel test issues
+- **Store configuration** for consistent future runs

+# Run Tests
+
+Execute tests with the configured test-runner agent.
+
+## Usage
+```
+/testing:run [test_target]
+```
+
+Where `test_target` can be:
+- Empty (run all tests)
+- Test file path
+- Test pattern
+- Test suite name
+
+## Quick Check
+
+```bash
+# Check if testing is configured

+# For file targets
+test -f "$ARGUMENTS" || echo "⚠️ Test file not found: $ARGUMENTS"
+```
+
+## Instructions
+
+### 1. Determine Test Command
+
+Based on testing-config.md and target:
+- No arguments → Run full test suite from config
+- File path → Run specific test file
+- Pattern → Run tests matching pattern
+
+### 2. Execute Tests
+
+Use the test-runner agent from `.claude/agents/test-runner.md`:
+
+```markdown
+Execute tests for: $ARGUMENTS (or "all" if empty)
+
+Requirements:
+- Run with verbose output for debugging
+- No mocks - use real services
+- Capture full output including stack traces
+- If test fails, check test structure before assuming code issue
+```
+
+### 3. Monitor Execution
+
+- Show test progress
+- Capture stdout and stderr
+- Note execution time
+
+### 4. Report Results
+
+**Success:**
+```
+✅ All tests passed ({count} tests in {time}s)
+```
+
+**Failure:**
+```
+❌ Test failures: {failed_count} of {total_count}
+
+{test_name} - {file}:{line}
+  Error: {error_message}
+  Likely: {test issue | code issue}
+  Fix: {suggestion}
+
+Run with more detail: /testing:run {specific_test}
+```
+
+**Mixed:**
+```
+Tests complete: {passed} passed, {failed} failed, {skipped} skipped
+
+Failed:
+- {test_1}: {brief_reason}
+- {test_2}: {brief_reason}
+```
+
+### 5. Cleanup
+
+```bash
+# Kill any hanging test processes
+pkill -f "jest|mocha|pytest" 2>/dev/null || true
+```
+
+## Error Handling
+
+- Test command fails → "❌ Test execution failed: {error}. Check test framework is installed."
+- Timeout → Kill process and report: "❌ Tests timed out after {time}s"
+- No tests found → "❌ No tests found matching: $ARGUMENTS"
+
+## Important Notes
+
+- Always use test-runner agent for analysis
+- No mocking - real services only
+- Check test structure if failures occur
+- Keep output focused on failures

+This directory contains project context documentation that provides comprehensive information about the current state, structure, and direction of your project. The context files serve as a knowledge base for AI agents and team members to quickly understand and contribute to the project.
+
+## Purpose
+
+The context system enables:
+- **Fast Agent Onboarding**: New AI agents can quickly understand the project through standardized documentation
+- **Project Continuity**: Maintain knowledge across development sessions and team changes
+- **Consistent Understanding**: Ensure all contributors have access to the same project information
+- **Living Documentation**: Keep project knowledge current and actionable
+
+## Core Context Files
+
+When fully initialized, this directory contains:
+
+### Project Foundation
+- **`project-brief.md`** - Project scope, goals, and key objectives
+- **`project-vision.md`** - Long-term vision and strategic direction
+- **`project-overview.md`** - High-level summary of features and capabilities
+- **`progress.md`** - Current project status, completed work, and immediate next steps
+
+### Technical Context
+- **`tech-context.md`** - Dependencies, technologies, and development tools
+- **`project-structure.md`** - Directory structure and file organization
+- **`system-patterns.md`** - Architectural patterns and design decisions
+- **`project-style-guide.md`** - Coding standards, conventions, and style preferences
+
+### Product Context
+- **`product-context.md`** - Product requirements, target users, and core functionality
+
+## Context Commands
+
+Use these commands to manage your project context:
+
+### Initialize Context
+```bash
+/context:create
+```
+Analyzes your project and creates initial context documentation. Use this when:
+- Starting a new project
+- Adding context to an existing project
+- Major project restructuring
+
+### Load Context
+```bash
+/context:prime
+```
+Loads all context information for a new agent session. Use this when:
+- Starting a new development session
+- Onboarding a new team member
+- Getting up to speed on project status
+
+### Update Context
+```bash
+/context:update
+```
+Updates context documentation to reflect current project state. Use this:
+- At the end of development sessions
+- After completing major features
+- When project direction changes
+- After architectural changes
+
+## Context Workflow
+
+1. **Project Start**: Run `/context:create` to establish baseline documentation
+2. **Session Start**: Run `/context:prime` to load current context
+3. **Development**: Work on your project with full context awareness
+4. **Session End**: Run `/context:update` to capture changes and progress
+
+## Benefits
+
+- **Reduced Onboarding Time**: New contributors understand the project quickly
+- **Maintained Project Memory**: Nothing gets lost between sessions
+- **Consistent Architecture**: Decisions are documented and followed
+- **Clear Progress Tracking**: Always know what's been done and what's next
+- **Enhanced AI Collaboration**: AI agents have full project understanding
+
+## Best Practices
+
+- **Keep Current**: Update context regularly, especially after major changes
+- **Be Concise**: Focus on essential information that helps understanding
+- **Stay Consistent**: Follow established formats and structures
+- **Document Decisions**: Capture architectural and design decisions
+- **Track Progress**: Maintain accurate status and next steps
+
+## Integration
+
+The context system integrates with:
+- **Project Management**: Links with PRDs, epics, and task tracking
+- **Development Workflow**: Supports continuous development sessions
+- **Documentation**: Complements existing project documentation
+- **Team Collaboration**: Provides shared understanding across contributors
+
+Start with `/context:create` to initialize your project's knowledge base!

+# Agent Coordination
+
+Rules for multiple agents working in parallel within the same epic worktree.
+
+## Parallel Execution Principles
+
+1. **File-level parallelism** - Agents working on different files never conflict
+2. **Explicit coordination** - When same file needed, coordinate explicitly
+3. **Fail fast** - Surface conflicts immediately, don't try to be clever
+4. **Human resolution** - Conflicts are resolved by humans, not agents
+
+## Work Stream Assignment
+
+Each agent is assigned a work stream from the issue analysis:
+```yaml
+# From {issue}-analysis.md
+Stream A: Database Layer
+  Files: src/db/*, migrations/*
+  Agent: backend-specialist
+
+Stream B: API Layer
+  Files: src/api/*
+  Agent: api-specialist
+```
+
+Agents should only modify files in their assigned patterns.
+
+## File Access Coordination
+
+### Check Before Modify
+Before modifying a shared file:
+```bash
+# Check if file is being modified
+git status {file}
+
+# If modified by another agent, wait
+if [[ $(git status --porcelain {file}) ]]; then
+  echo "Waiting for {file} to be available..."
+  sleep 30
+  # Retry
+fi
+```
+
+### Atomic Commits
+Make commits atomic and focused:
+```bash
+# Good - Single purpose commit
+git add src/api/users.ts src/api/users.test.ts
+git commit -m "Issue #1234: Add user CRUD endpoints"
+
+# Bad - Mixed concerns
+git add src/api/* src/db/* src/ui/*
+git commit -m "Issue #1234: Multiple changes"
+```
+
+## Communication Between Agents
+
+### Through Commits
+Agents see each other's work through commits:
+```bash
+# Agent checks what others have done
+git log --oneline -10
+
+# Agent pulls latest changes
+git pull origin epic/{name}
+```
+
+### Through Progress Files
+Each stream maintains progress:
+```markdown
+# .claude/epics/{epic}/updates/{issue}/stream-A.md
+---
+stream: Database Layer
+agent: backend-specialist
+started: {datetime}
+status: in_progress
+---
+
+## Completed
+- Created user table schema
+- Added migration files
+
+## Working On
+- Adding indexes
+
+## Blocked
+- None
+```
+
+### Through Analysis Files
+The analysis file is the contract:
+```yaml
+# Agents read this to understand boundaries
+Stream A:
+  Files: src/db/*  # Agent A only touches these
+Stream B:
+  Files: src/api/* # Agent B only touches these
+```
+
+## Handling Conflicts
+
+### Conflict Detection
+```bash
+# If commit fails due to conflict
+git commit -m "Issue #1234: Update"
+# Error: conflicts exist
+
+# Agent should report and wait
+echo "❌ Conflict detected in {files}"
+echo "Human intervention needed"
+```
+
+### Conflict Resolution
+Always defer to humans:
+1. Agent detects conflict
+2. Agent reports issue
+3. Agent pauses work
+4. Human resolves
+5. Agent continues
+
+Never attempt automatic merge resolution.
+
+## Synchronization Points
+
+### Natural Sync Points
+- After each commit
+- Before starting new file
+- When switching work streams
+- Every 30 minutes of work
+
+### Explicit Sync
+```bash
+# Pull latest changes
+git pull --rebase origin epic/{name}
+
+# If conflicts, stop and report
+if [[ $? -ne 0 ]]; then
+  echo "❌ Sync failed - human help needed"
+  exit 1
+fi
+```
+
+## Agent Communication Protocol
+
+### Status Updates
+Agents should update their status regularly:
+```bash
+# Update progress file every significant step
+echo "✅ Completed: Database schema" >> stream-A.md
+git add stream-A.md
+git commit -m "Progress: Stream A - schema complete"
+```
+
+### Coordination Requests
+When agents need to coordinate:
+```markdown
+# In stream-A.md
+## Coordination Needed
+- Need to update src/types/index.ts
+- Will modify after Stream B commits
+- ETA: 10 minutes
+```
+
+## Parallel Commit Strategy
+
+### No Conflicts Possible
+When working on completely different files:
+```bash
+# These can happen simultaneously
+Agent-A: git commit -m "Issue #1234: Update database"
+Agent-B: git commit -m "Issue #1235: Update UI"
+Agent-C: git commit -m "Issue #1236: Add tests"
+```
+
+### Sequential When Needed
+When touching shared resources:
+```bash
+# Agent A commits first
+git add src/types/index.ts
+git commit -m "Issue #1234: Update type definitions"
+
+# Agent B waits, then proceeds
+# (After A's commit)
+git pull
+git add src/api/users.ts
+git commit -m "Issue #1235: Use new types"
+```
+
+## Best Practices
+
+1. **Commit early and often** - Smaller commits = fewer conflicts
+2. **Stay in your lane** - Only modify assigned files
+3. **Communicate changes** - Update progress files
+4. **Pull frequently** - Stay synchronized with other agents
+5. **Fail loudly** - Report issues immediately
+6. **Never force** - No `--force` flags ever
+
+## Common Patterns
+
+### Starting Work
+```bash
+1. cd ../epic-{name}
+2. git pull
+3. Check {issue}-analysis.md for assignment
+4. Update stream-{X}.md with "started"
+5. Begin work on assigned files
+```
+
+### During Work
+```bash
+1. Make changes to assigned files
+2. Commit with clear message
+3. Update progress file
+4. Check for new commits from others
+5. Continue or coordinate as needed
+```
+
+### Completing Work
+```bash
+1. Final commit for stream
+2. Update stream-{X}.md with "completed"
+3. Check if other streams need help
+4. Report completion
+```

+# Branch Operations
+
+Git branches enable parallel development by allowing multiple developers to work on the same repository with isolated changes.
+
+## Creating Branches
+
+Always create branches from a clean main branch:
+```bash
+# Ensure main is up to date
+git checkout main
+git pull origin main
+
+# Create branch for epic
+git checkout -b epic/{name}
+git push -u origin epic/{name}
+```
+
+The branch will be created and pushed to origin with upstream tracking.
+
+## Working in Branches
+
+### Agent Commits
+- Agents commit directly to the branch
+- Use small, focused commits
+- Commit message format: `Issue #{number}: {description}`
+- Example: `Issue #1234: Add user authentication schema`
+
+### File Operations
+```bash
+# Working directory is the current directory
+# (no need to change directories like with worktrees)
+
+# Normal git operations work
+git add {files}
+git commit -m "Issue #{number}: {change}"
+
+# View branch status
+git status
+git log --oneline -5
+```
+
+## Parallel Work in Same Branch
+
+Multiple agents can work in the same branch if they coordinate file access:
+```bash
+# Agent A works on API
+git add src/api/*
+git commit -m "Issue #1234: Add user endpoints"
+
+# Agent B works on UI (coordinate to avoid conflicts!)
+git pull origin epic/{name}  # Get latest changes
+git add src/ui/*
+git commit -m "Issue #1235: Add dashboard component"
+```
+
+## Merging Branches
+
+When epic is complete, merge back to main:
+```bash
+# From main repository
+git checkout main
+git pull origin main
+
+# Merge epic branch
+git merge epic/{name}
+
+# If successful, clean up
+git branch -d epic/{name}
+git push origin --delete epic/{name}
+```
+
+## Handling Conflicts
+
+If merge conflicts occur:
+```bash
+# Conflicts will be shown
+git status
+
+# Human resolves conflicts
+# Then continue merge
+git add {resolved-files}
+git commit
+```
+
+## Branch Management
+
+### List Active Branches
+```bash
+git branch -a
+```
+
+### Remove Stale Branch
+```bash
+# Delete local branch
+git branch -d epic/{name}
+
+# Delete remote branch
+git push origin --delete epic/{name}
+```
+
+### Check Branch Status
+```bash
+# Current branch info
+git branch -v
+
+# Compare with main
+git log --oneline main..epic/{name}
+```
+
+## Best Practices
+
+1. **One branch per epic** - Not per issue
+2. **Clean before create** - Always start from updated main
+3. **Commit frequently** - Small commits are easier to merge
+4. **Pull before push** - Get latest changes to avoid conflicts
+5. **Use descriptive branches** - `epic/feature-name` not `feature`
+
+## Common Issues
+
+### Branch Already Exists
+```bash
+# Delete old branch first
+git branch -D epic/{name}
+git push origin --delete epic/{name}
+# Then create new one
+```
+
+### Cannot Push Branch
+```bash
+# Check if branch exists remotely
+git ls-remote origin epic/{name}
+
+# Push with upstream
+git push -u origin epic/{name}
+```
+
+### Merge Conflicts During Pull
+```bash
+# Stash changes if needed
+git stash
+
+# Pull and rebase
+git pull --rebase origin epic/{name}
+
+# Restore changes
+git stash pop
+```

+# DateTime Rule
+
+## Getting Current Date and Time
+
+When any command requires the current date/time (for frontmatter, timestamps, or logs), you MUST obtain the REAL current date/time from the system rather than estimating or using placeholder values.
+
+### How to Get Current DateTime
+
+Use the `date` command to get the current ISO 8601 formatted datetime:
+
+```bash
+# Get current datetime in ISO 8601 format (works on Linux/Mac)
+date -u +"%Y-%m-%dT%H:%M:%SZ"
+
+# Alternative for systems that support it
+date --iso-8601=seconds
+
+# For Windows (if using PowerShell)
+Get-Date -Format "yyyy-MM-ddTHH:mm:ssZ"
+```
+
+### Required Format
+
+All dates in frontmatter MUST use ISO 8601 format with UTC timezone:
+- Format: `YYYY-MM-DDTHH:MM:SSZ`
+- Example: `2024-01-15T14:30:45Z`
+
+### Usage in Frontmatter
+
+When creating or updating frontmatter in any file (PRD, Epic, Task, Progress), always use the real current datetime:
+
+```yaml
+---
+name: feature-name
+created: 2024-01-15T14:30:45Z  # Use actual output from date command
+updated: 2024-01-15T14:30:45Z  # Use actual output from date command
+---
+```
+
+### Implementation Instructions
+
+1. **Before writing any file with frontmatter:**
+   - Run: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+   - Store the output
+   - Use this exact value in the frontmatter
+
+2. **For commands that create files:**
+   - PRD creation: Use real date for `created` field
+   - Epic creation: Use real date for `created` field
+   - Task creation: Use real date for both `created` and `updated` fields
+   - Progress tracking: Use real date for `started` and `last_sync` fields
+
+3. **For commands that update files:**
+   - Always update the `updated` field with current real datetime
+   - Preserve the original `created` field
+   - For sync operations, update `last_sync` with real datetime
+
+### Examples
+
+**Creating a new PRD:**
+```bash
+# First, get current datetime
+CURRENT_DATE=$(date -u +"%Y-%m-%dT%H:%M:%SZ")
+# Output: 2024-01-15T14:30:45Z
+
+# Then use in frontmatter:
+---
+name: user-authentication
+description: User authentication and authorization system
+status: backlog
+created: 2024-01-15T14:30:45Z  # Use the actual $CURRENT_DATE value
+---
+```
+
+**Updating an existing task:**
+```bash
+# Get current datetime for update
+UPDATE_DATE=$(date -u +"%Y-%m-%dT%H:%M:%SZ")
+
+# Update only the 'updated' field:
+---
+name: implement-login-api
+status: in-progress
+created: 2024-01-10T09:15:30Z  # Keep original
+updated: 2024-01-15T14:30:45Z  # Use new $UPDATE_DATE value
+---
+```
+
+### Important Notes
+
+- **Never use placeholder dates** like `[Current ISO date/time]` or `YYYY-MM-DD`
+- **Never estimate dates** - always get the actual system time
+- **Always use UTC** (the `Z` suffix) for consistency across timezones
+- **Preserve timezone consistency** - all dates in the system use UTC
+
+### Cross-Platform Compatibility
+
+If you need to ensure compatibility across different systems:
+
+```bash
+# Try primary method first
+date -u +"%Y-%m-%dT%H:%M:%SZ" 2>/dev/null || \
+# Fallback for systems without -u flag
+date +"%Y-%m-%dT%H:%M:%SZ" 2>/dev/null || \
+# Last resort: use Python if available
+python3 -c "from datetime import datetime; print(datetime.utcnow().strftime('%Y-%m-%dT%H:%M:%SZ'))" 2>/dev/null || \
+python -c "from datetime import datetime; print(datetime.utcnow().strftime('%Y-%m-%dT%H:%M:%SZ'))" 2>/dev/null
+```
+
+## Rule Priority
+
+This rule has **HIGHEST PRIORITY** and must be followed by all commands that:
+- Create new files with frontmatter
+- Update existing files with frontmatter
+- Track timestamps or progress
+- Log any time-based information
+
+Commands affected: prd-new, prd-parse, epic-decompose, epic-sync, issue-start, issue-sync, and any other command that writes timestamps.

+# Frontmatter Operations Rule
+
+Standard patterns for working with YAML frontmatter in markdown files.
+
+## Reading Frontmatter
+
+Extract frontmatter from any markdown file:
+1. Look for content between `---` markers at start of file
+2. Parse as YAML
+3. If invalid or missing, use sensible defaults
+
+## Updating Frontmatter
+
+When updating existing files:
+1. Preserve all existing fields
+2. Only update specified fields
+3. Always update `updated` field with current datetime (see `/rules/datetime.md`)
+
+## Standard Fields
+
+### All Files
+```yaml
+---
+name: {identifier}
+created: {ISO datetime}      # Never change after creation
+updated: {ISO datetime}      # Update on any modification
+---
+```
+
+### Status Values
+- PRDs: `backlog`, `in-progress`, `complete`
+- Epics: `backlog`, `in-progress`, `completed`  
+- Tasks: `open`, `in-progress`, `closed`
+
+### Progress Tracking
+```yaml
+progress: {0-100}%           # For epics
+completion: {0-100}%         # For progress files
+```
+
+## Creating New Files
+
+Always include frontmatter when creating markdown files:
+```yaml
+---
+name: {from_arguments_or_context}
+status: {initial_status}
+created: {current_datetime}
+updated: {current_datetime}
+---
+```
+
+## Important Notes
+
+- Never modify `created` field after initial creation
+- Always use real datetime from system (see `/rules/datetime.md`)
+- Validate frontmatter exists before trying to parse
+- Use consistent field names across all files

+# GitHub Operations Rule
+
+Standard patterns for GitHub CLI operations across all commands.
+
+## CRITICAL: Repository Protection
+
+**Before ANY GitHub operation that creates/modifies issues or PRs:**
+
+```bash
+# Check if remote origin is the CCPM template repository
+remote_url=$(git remote get-url origin 2>/dev/null || echo "")
+if [[ "$remote_url" == *"automazeio/ccpm"* ]] || [[ "$remote_url" == *"automazeio/ccpm.git"* ]]; then
+  echo "❌ ERROR: You're trying to sync with the CCPM template repository!"
+  echo ""
+  echo "This repository (automazeio/ccpm) is a template for others to use."
+  echo "You should NOT create issues or PRs here."
+  echo ""
+  echo "To fix this:"
+  echo "1. Fork this repository to your own GitHub account"
+  echo "2. Update your remote origin:"
+  echo "   git remote set-url origin https://github.com/YOUR_USERNAME/YOUR_REPO.git"
+  echo ""
+  echo "Or if this is a new project:"
+  echo "1. Create a new repository on GitHub"
+  echo "2. Update your remote origin:"
+  echo "   git remote set-url origin https://github.com/YOUR_USERNAME/YOUR_REPO.git"
+  echo ""
+  echo "Current remote: $remote_url"
+  exit 1
+fi
+```
+
+This check MUST be performed in ALL commands that:
+- Create issues (`gh issue create`)
+- Edit issues (`gh issue edit`)
+- Comment on issues (`gh issue comment`)
+- Create PRs (`gh pr create`)
+- Any other operation that modifies the GitHub repository
+
+## Authentication
+
+**Don't pre-check authentication.** Just run the command and handle failure:
+
+```bash
+gh {command} || echo "❌ GitHub CLI failed. Run: gh auth login"
+```
+
+## Common Operations
+
+### Get Issue Details
+```bash
+gh issue view {number} --json state,title,labels,body
+```
+
+### Create Issue
+```bash
+# ALWAYS check remote origin first!
+gh issue create --title "{title}" --body-file {file} --label "{labels}"
+```
+
+### Update Issue
+```bash
+# ALWAYS check remote origin first!
+gh issue edit {number} --add-label "{label}" --add-assignee @me
+```
+
+### Add Comment
+```bash
+# ALWAYS check remote origin first!
+gh issue comment {number} --body-file {file}
+```
+
+## Error Handling
+
+If any gh command fails:
+1. Show clear error: "❌ GitHub operation failed: {command}"
+2. Suggest fix: "Run: gh auth login" or check issue number
+3. Don't retry automatically
+
+## Important Notes
+
+- **ALWAYS** check remote origin before ANY write operation to GitHub
+- Trust that gh CLI is installed and authenticated
+- Use --json for structured output when parsing
+- Keep operations atomic - one gh command per action
+- Don't check rate limits preemptively

+# Standard Patterns for Commands
+
+This file defines common patterns that all commands should follow to maintain consistency and simplicity.
+
+## Core Principles
+
+1. **Fail Fast** - Check critical prerequisites, then proceed
+2. **Trust the System** - Don't over-validate things that rarely fail
+3. **Clear Errors** - When something fails, say exactly what and how to fix it
+4. **Minimal Output** - Show what matters, skip decoration
+
+## Standard Validations
+
+### Minimal Preflight
+Only check what's absolutely necessary:
+```markdown
+## Quick Check
+1. If command needs specific directory/file:
+   - Check it exists: `test -f {file} || echo "❌ {file} not found"`
+   - If missing, tell user exact command to fix it
+2. If command needs GitHub:
+   - Assume `gh` is authenticated (it usually is)
+   - Only check on actual failure
+```
+
+### DateTime Handling
+```markdown
+Get current datetime: `date -u +"%Y-%m-%dT%H:%M:%SZ"`
+```
+Don't repeat full instructions - just reference `/rules/datetime.md` once.
+
+### Error Messages
+Keep them short and actionable:
+```markdown
+❌ {What failed}: {Exact solution}
+Example: "❌ Epic not found: Run /pm:prd-parse feature-name"
+```
+
+## Standard Output Formats
+
+### Success Output
+```markdown
+✅ {Action} complete
+  - {Key result 1}
+  - {Key result 2}
+Next: {Single suggested action}
+```
+
+### List Output
+```markdown
+{Count} {items} found:
+- {item 1}: {key detail}
+- {item 2}: {key detail}
+```
+
+### Progress Output
+```markdown
+{Action}... {current}/{total}
+```
+
+## File Operations
+
+### Check and Create
+```markdown
+# Don't ask permission, just create what's needed
+mkdir -p .claude/{directory} 2>/dev/null
+```
+
+### Read with Fallback
+```markdown
+# Try to read, continue if missing
+if [ -f {file} ]; then
+  # Read and use file
+else
+  # Use sensible default
+fi
+```
+
+## GitHub Operations
+
+### Trust gh CLI
+```markdown
+# Don't pre-check auth, just try the operation
+gh {command} || echo "❌ GitHub CLI failed. Run: gh auth login"
+```
+
+### Simple Issue Operations
+```markdown
+# Get what you need in one call
+gh issue view {number} --json state,title,body
+```
+
+## Common Patterns to Avoid
+
+### DON'T: Over-validate
+```markdown
+# Bad - too many checks
+1. Check directory exists
+2. Check permissions
+3. Check git status
+4. Check GitHub auth
+5. Check rate limits
+6. Validate every field
+```
+
+### DO: Check essentials
+```markdown
+# Good - just what's needed
+1. Check target exists
+2. Try the operation
+3. Handle failure clearly
+```
+
+### DON'T: Verbose output
+```markdown
+# Bad - too much information
+🎯 Starting operation...
+📋 Validating prerequisites...
+✅ Step 1 complete
+✅ Step 2 complete
+📊 Statistics: ...
+💡 Tips: ...
+```
+
+### DO: Concise output
+```markdown
+# Good - just results
+✅ Done: 3 files created
+Failed: auth.test.js (syntax error - line 42)
+```
+
+### DON'T: Ask too many questions
+```markdown
+# Bad - too interactive
+"Continue? (yes/no)"
+"Overwrite? (yes/no)"
+"Are you sure? (yes/no)"
+```
+
+### DO: Smart defaults
+```markdown
+# Good - proceed with sensible defaults
+# Only ask when destructive or ambiguous
+"This will delete 10 files. Continue? (yes/no)"
+```
+
+## Quick Reference
+
+### Essential Tools Only
+- Read/List operations: `Read, LS`
+- File creation: `Read, Write, LS`
+- GitHub operations: Add `Bash`
+- Complex analysis: Add `Task` (sparingly)
+
+### Status Indicators
+- ✅ Success (use sparingly)
+- ❌ Error (always with solution)
+- ⚠️ Warning (only if action needed)
+- No emoji for normal output
+
+### Exit Strategies
+- Success: Brief confirmation
+- Failure: Clear error + exact fix
+- Partial: Show what worked, what didn't
+
+## Remember
+
+**Simple is not simplistic** - We still handle errors properly, we just don't try to prevent every possible edge case. We trust that:
+- The file system usually works
+- GitHub CLI is usually authenticated  
+- Git repositories are usually valid
+- Users know what they're doing
+
+Focus on the happy path, fail gracefully when things go wrong.

+# Strip Frontmatter
+
+Standard approach for removing YAML frontmatter before sending content to GitHub.
+
+## The Problem
+
+YAML frontmatter contains internal metadata that should not appear in GitHub issues:
+- status, created, updated fields
+- Internal references and IDs
+- Local file paths
+
+## The Solution
+
+Use sed to strip frontmatter from any markdown file:
+
+```bash
+# Strip frontmatter (everything between first two --- lines)
+sed '1,/^---$/d; 1,/^---$/d' input.md > output.md
+```
+
+This removes:
+1. The opening `---` line
+2. All YAML content
+3. The closing `---` line
+
+## When to Strip Frontmatter
+
+Always strip frontmatter when:
+- Creating GitHub issues from markdown files
+- Posting file content as comments
+- Displaying content to external users
+- Syncing to any external system
+
+## Examples
+
+### Creating an issue from a file
+```bash
+# Bad - includes frontmatter
+gh issue create --body-file task.md
+
+# Good - strips frontmatter
+sed '1,/^---$/d; 1,/^---$/d' task.md > /tmp/clean.md
+gh issue create --body-file /tmp/clean.md
+```
+
+### Posting a comment
+```bash
+# Strip frontmatter before posting
+sed '1,/^---$/d; 1,/^---$/d' progress.md > /tmp/comment.md
+gh issue comment 123 --body-file /tmp/comment.md
+```
+
+### In a loop
+```bash
+for file in *.md; do
+  # Strip frontmatter from each file
+  sed '1,/^---$/d; 1,/^---$/d' "$file" > "/tmp/$(basename $file)"
+  # Use the clean version
+done
+```
+
+## Alternative Approaches
+
+If sed is not available or you need more control:
+
+```bash
+# Using awk
+awk 'BEGIN{fm=0} /^---$/{fm++; next} fm==2{print}' input.md > output.md
+
+# Using grep with line numbers
+grep -n "^---$" input.md | head -2 | tail -1 | cut -d: -f1 | xargs -I {} tail -n +$(({}+1)) input.md
+```
+
+## Important Notes
+
+- Always test with a sample file first
+- Keep original files intact
+- Use temporary files for cleaned content
+- Some files may not have frontmatter - the command handles this gracefully

+# Test Execution Rule
+
+Standard patterns for running tests across all testing commands.
+
+## Core Principles
+
+1. **Always use test-runner agent** from `.claude/agents/test-runner.md`
+2. **No mocking** - use real services for accurate results
+3. **Verbose output** - capture everything for debugging
+4. **Check test structure first** - before assuming code bugs
+
+## Execution Pattern
+
+```markdown
+Execute tests for: {target}
+
+Requirements:
+- Run with verbose output
+- No mock services
+- Capture full stack traces
+- Analyze test structure if failures occur
+```
+
+## Output Focus
+
+### Success
+Keep it simple:
+```
+✅ All tests passed ({count} tests in {time}s)
+```
+
+### Failure
+Focus on what failed:
+```
+❌ Test failures: {count}
+
+{test_name} - {file}:{line}
+  Error: {message}
+  Fix: {suggestion}
+```
+
+## Common Issues
+
+- Test not found → Check file path
+- Timeout → Kill process, report incomplete
+- Framework missing → Install dependencies
+
+## Cleanup
+
+Always clean up after tests:
+```bash
+pkill -f "jest|mocha|pytest" 2>/dev/null || true
+```
+
+## Important Notes
+
+- Don't parallelize tests (avoid conflicts)
+- Let each test complete fully
+- Report failures with actionable fixes
+- Focus output on failures, not successes

+# AST-Grep Integration Protocol for Cursor Agent
+
+## When to Use AST-Grep
+
+Use `ast-grep` (if installed) instead of plain regex or text search when:
+
+- **Structural code patterns** are involved (e.g., finding all function calls, class definitions, or method implementations)
+- **Language-aware refactoring** is required (e.g., renaming variables, updating function signatures, or changing imports)
+- **Complex code analysis** is needed (e.g., finding all usages of a pattern across different syntactic contexts)
+- **Cross-language searches** are necessary (e.g., working with both Ruby and TypeScript in a monorepo)
+- **Semantic code understanding** is important (e.g., finding patterns based on code structure, not just text)
+
+## AST-Grep Command Patterns
+
+### Basic Search Template:
+```sh
+ast-grep --pattern '$PATTERN' --lang $LANGUAGE $PATH
+```
+
+### Common Use Cases
+
+- **Find function calls:**
+  `ast-grep --pattern 'functionName($$$)' --lang javascript .`
+- **Find class definitions:**
+  `ast-grep --pattern 'class $NAME { $$$ }' --lang typescript .`
+- **Find variable assignments:**
+  `ast-grep --pattern '$VAR = $$$' --lang ruby .`
+- **Find import statements:**
+  `ast-grep --pattern 'import { $$$ } from "$MODULE"' --lang javascript .`
+- **Find method calls on objects:**
+  `ast-grep --pattern '$OBJ.$METHOD($$$)' --lang typescript .`
+- **Find React hooks:**
+  `ast-grep --pattern 'const [$STATE, $SETTER] = useState($$$)' --lang typescript .`
+- **Find Ruby class definitions:**
+  `ast-grep --pattern 'class $NAME < $$$; $$$; end' --lang ruby .`
+
+## Pattern Syntax Reference
+
+- `$VAR` — matches any single node and captures it
+- `$$$` — matches zero or more nodes (wildcard)
+- `$$` — matches one or more nodes
+- Literal code — matches exactly as written
+
+## Supported Languages
+
+- javascript, typescript, ruby, python, go, rust, java, c, cpp, html, css, yaml, json, and more
+
+## Integration Workflow
+
+### Before using ast-grep:
+1. **Check if ast-grep is installed:**
+   If not, skip and fall back to regex/semantic search.
+   ```sh
+   command -v ast-grep >/dev/null 2>&1 || echo "ast-grep not installed, skipping AST search"
+   ```
+2. **Identify** if the task involves structural code patterns or language-aware refactoring.
+3. **Determine** the appropriate language(s) to search.
+4. **Construct** the pattern using ast-grep syntax.
+5. **Run** ast-grep to gather precise structural information.
+6. **Use** results to inform code edits, refactoring, or further analysis.
+
+### Example Workflow
+
+When asked to "find all Ruby service objects that call `perform`":
+
+1. **Check for ast-grep:**
+   ```sh
+   command -v ast-grep >/dev/null 2>&1 && ast-grep --pattern 'perform($$$)' --lang ruby app/services/
+   ```
+2. **Analyze** results structurally.
+3. **Use** codebase semantic search for additional context if needed.
+4. **Make** informed edits based on structural understanding.
+
+### Combine ast-grep with Internal Tools
+
+- **codebase_search** for semantic context and documentation
+- **read_file** for examining specific files found by ast-grep
+- **edit_file** for making precise, context-aware code changes
+
+### Advanced Usage
+- **JSON output for programmatic processing:**
+  `ast-grep --pattern '$PATTERN' --lang $LANG $PATH --json`
+- **Replace patterns:**
+  `ast-grep --pattern '$OLD_PATTERN' --rewrite '$NEW_PATTERN' --lang $LANG $PATH`
+- **Interactive mode:**
+  `ast-grep --pattern '$PATTERN' --lang $LANG $PATH --interactive`
+
+## Key Benefits Over Regex
+
+1. **Language-aware** — understands syntax and semantics
+2. **Structural matching** — finds patterns regardless of formatting
+3. **Cross-language** — works consistently across different languages
+4. **Precise refactoring** — makes structural changes safely
+5. **Context-aware** — understands code hierarchy and scope
+
+## Decision Matrix: When to Use Each Tool
+
+| Task Type                | Tool Choice          | Reason                        |
+|--------------------------|----------------------|-------------------------------|
+| Find text patterns       | grep_search          | Simple text matching          |
+| Find code structures     | ast-grep             | Syntax-aware search           |
+| Understand semantics     | codebase_search      | AI-powered context            |
+| Make edits               | edit_file            | Precise file editing          |
+| Structural refactoring   | ast-grep + edit_file | Structure + precision         |
+
+**Always prefer ast-grep for code structure analysis over regex-based approaches, but only if it is installed and available.**

+# Worktree Operations
+
+Git worktrees enable parallel development by allowing multiple working directories for the same repository.
+
+## Creating Worktrees
+
+Always create worktrees from a clean main branch:
+```bash
+# Ensure main is up to date
+git checkout main
+git pull origin main
+
+# Create worktree for epic
+git worktree add ../epic-{name} -b epic/{name}
+```
+
+The worktree will be created as a sibling directory to maintain clean separation.
+
+## Working in Worktrees
+
+### Agent Commits
+- Agents commit directly to the worktree
+- Use small, focused commits
+- Commit message format: `Issue #{number}: {description}`
+- Example: `Issue #1234: Add user authentication schema`
+
+### File Operations
+```bash
+# Working directory is the worktree
+cd ../epic-{name}
+
+# Normal git operations work
+git add {files}
+git commit -m "Issue #{number}: {change}"
+
+# View worktree status
+git status
+```
+
+## Parallel Work in Same Worktree
+
+Multiple agents can work in the same worktree if they touch different files:
+```bash
+# Agent A works on API
+git add src/api/*
+git commit -m "Issue #1234: Add user endpoints"
+
+# Agent B works on UI (no conflict!)
+git add src/ui/*
+git commit -m "Issue #1235: Add dashboard component"
+```
+
+## Merging Worktrees
+
+When epic is complete, merge back to main:
+```bash
+# From main repository (not worktree)
+cd {main-repo}
+git checkout main
+git pull origin main
+
+# Merge epic branch
+git merge epic/{name}
+
+# If successful, clean up
+git worktree remove ../epic-{name}
+git branch -d epic/{name}
+```
+
+## Handling Conflicts
+
+If merge conflicts occur:
+```bash
+# Conflicts will be shown
+git status
+
+# Human resolves conflicts
+# Then continue merge
+git add {resolved-files}
+git commit
+```
+
+## Worktree Management
+
+### List Active Worktrees
+```bash
+git worktree list
+```
+
+### Remove Stale Worktree
+```bash
+# If worktree directory was deleted
+git worktree prune
+
+# Force remove worktree
+git worktree remove --force ../epic-{name}
+```
+
+### Check Worktree Status
+```bash
+# From main repo
+cd ../epic-{name} && git status && cd -
+```
+
+## Best Practices
+
+1. **One worktree per epic** - Not per issue
+2. **Clean before create** - Always start from updated main
+3. **Commit frequently** - Small commits are easier to merge
+4. **Delete after merge** - Don't leave stale worktrees
+5. **Use descriptive branches** - `epic/feature-name` not `feature`
+
+## Common Issues
+
+### Worktree Already Exists
+```bash
+# Remove old worktree first
+git worktree remove ../epic-{name}
+# Then create new one
+```
+
+### Branch Already Exists
+```bash
+# Delete old branch
+git branch -D epic/{name}
+# Or use existing branch
+git worktree add ../epic-{name} epic/{name}
+```
+
+### Cannot Remove Worktree
+```bash
+# Force removal
+git worktree remove --force ../epic-{name}
+# Clean up references
+git worktree prune
+```

+# Agents
+
+Specialized agents that do heavy work and return concise summaries to preserve context.
+
+## Core Philosophy
+
+> “Don't anthropomorphize subagents. Use them to organize your prompts and elide context. Subagents are best when they can do lots of work but then provide small amounts of information back to the main conversation thread.”
+>
+> – Adam Wolff, Anthropic
+
+## Available Agents
+
+### 🔍 `code-analyzer`
+- **Purpose**: Hunt bugs across multiple files without polluting main context
+- **Pattern**: Search many files → Analyze code → Return bug report
+- **Usage**: When you need to trace logic flows, find bugs, or validate changes
+- **Returns**: Concise bug report with critical findings only
+
+### 📄 `file-analyzer`
+- **Purpose**: Read and summarize verbose files (logs, outputs, configs)
+- **Pattern**: Read files → Extract insights → Return summary
+- **Usage**: When you need to understand log files or analyze verbose output
+- **Returns**: Key findings and actionable insights (80-90% size reduction)
+
+### 🧪 `test-runner`
+- **Purpose**: Execute tests without dumping output to main thread
+- **Pattern**: Run tests → Capture to log → Analyze results → Return summary
+- **Usage**: When you need to run tests and understand failures
+- **Returns**: Test results summary with failure analysis
+
+### 🔀 `parallel-worker`
+- **Purpose**: Coordinate multiple parallel work streams for an issue
+- **Pattern**: Read analysis → Spawn sub-agents → Consolidate results → Return summary
+- **Usage**: When executing parallel work streams in a worktree
+- **Returns**: Consolidated status of all parallel work
+
+## Why Agents?
+
+Agents are **context firewalls** that protect the main conversation from information overload:
+
+```
+Without Agent:
+Main thread reads 10 files → Context explodes → Loses coherence
+
+With Agent:
+Agent reads 10 files → Main thread gets 1 summary → Context preserved
+```
+
+## How Agents Preserve Context
+
+1. **Heavy Lifting** - Agents do the messy work (reading files, running tests, implementing features)
+2. **Context Isolation** - Implementation details stay in the agent, not the main thread
+3. **Concise Returns** - Only essential information returns to main conversation
+4. **Parallel Execution** - Multiple agents can work simultaneously without context collision
+
+## Example Usage
+
+```bash
+# Analyzing code for bugs
+Task: "Search for memory leaks in the codebase"
+Agent: code-analyzer
+Returns: "Found 3 potential leaks: [concise list]"
+Main thread never sees: The hundreds of files examined
+
+# Running tests
+Task: "Run authentication tests"
+Agent: test-runner
+Returns: "2/10 tests failed: [failure summary]"
+Main thread never sees: Verbose test output and logs
+
+# Parallel implementation
+Task: "Implement issue #1234 with parallel streams"
+Agent: parallel-worker
+Returns: "Completed 4/4 streams, 15 files modified"
+Main thread never sees: Individual implementation details
+```
+
+## Creating New Agents
+
+New agents should follow these principles:
+
+1. **Single Purpose** - Each agent has one clear job
+2. **Context Reduction** - Return 10-20% of what you process
+3. **No Roleplay** - Agents aren't "experts", they're task executors
+4. **Clear Pattern** - Define input → processing → output pattern
+5. **Error Handling** - Gracefully handle failures and report clearly
+
+## Anti-Patterns to Avoid
+
+❌ **Creating "specialist" agents** (database-expert, api-expert)
+   Agents don't have different knowledge - they're all the same model
+
+❌ **Returning verbose output**
+   Defeats the purpose of context preservation
+
+❌ **Making agents communicate with each other**
+   Use a coordinator agent instead (like parallel-worker)
+
+❌ **Using agents for simple tasks**
+   Only use agents when context reduction is valuable
+
+## Integration with PM System
+
+Agents integrate seamlessly with the PM command system:
+
+- `/pm:issue-analyze` → Identifies work streams
+- `/pm:issue-start` → Spawns parallel-worker agent
+- parallel-worker → Spawns multiple sub-agents
+- Sub-agents → Work in parallel in the worktree
+- Results → Consolidated back to main thread
+
+This creates a hierarchy that maximizes parallelism while preserving context at every level.

+   - Understands CodeRabbit lacks full context
+   - Accepts: Real bugs, security issues, resource leaks
+   - Ignores: Style preferences, irrelevant patterns
+   - Parallel processing for multiple files
+- **Output**: Summary of accepted/ignored suggestions with reasoning
+
+## Command Patterns
+
+All commands follow consistent patterns:
+
+### Allowed Tools
+Each command specifies its required tools in frontmatter:
+- `Read, Write, LS` - File operations
+- `Bash` - System commands
+- `Task` - Sub-agent spawning
+- `Grep` - Code searching
+
+### Error Handling
+Commands follow fail-fast principles:
+- Check prerequisites first
+- Clear error messages with solutions
+- Never leave partial state
+
+### Context Preservation
+Commands that process lots of information:
+- Use agents to shield main thread from verbose output
+- Return summaries, not raw data
+- Preserve only essential information
+
+## Creating Custom Commands
+
+To add new commands:
+
+1. **Create file**: `commands/category/command-name.md`
+2. **Add frontmatter**:
+   ```yaml
+   ---
+   allowed-tools: Read, Write, LS
+   ---
+   ```
+3. **Structure content**:
+   - Purpose and usage
+   - Preflight checks
+   - Step-by-step instructions
+   - Error handling
+   - Output format
+
+4. **Follow patterns**:
+   - Keep it simple (no over-validation)
+   - Fail fast with clear messages
+   - Use agents for heavy processing
+   - Return concise output
+
+## Integration with Agents
+
+Commands often use agents for heavy lifting:
+
+- **test-runner**: Executes tests, analyzes results
+- **file-analyzer**: Summarizes verbose files
+- **code-analyzer**: Hunts bugs across codebase
+- **parallel-worker**: Coordinates parallel execution
+
+This keeps the main conversation context clean while doing complex work.
+
+## Notes
+
+- Commands are markdown files interpreted as instructions
+- The `/` prefix triggers command execution
+- Commands can spawn agents for context preservation
+- All PM commands (`/pm:*`) are documented in the main README
+- Commands follow rules defined in `/rules/`

+
+## 代码规范
+
+### Python代码风格
+
+我们遵循以下工具和规范：
+
+- **Black**: 代码格式化
+- **flake8**: 代码风格检查
+- **isort**: 导入排序
+- **mypy**: 类型检查
+
+#### 格式化代码
+
+```bash
+# 格式化代码
+black src/ tests/
+isort src/ tests/
+
+# 检查格式
+black --check src/ tests/
+isort --check-only src/ tests/
+```
+
+#### 代码风格规则
+
+```python
+# 好的示例
+import os
+from typing import List, Dict
+
+class CodeProcessor:
+    """代码处理器类"""
+
+    def __init__(self, config: Dict[str, Any]):
+        self.config = config
+
+    def process_code(self, code: str) -> List[str]:
+        """处理代码
+
+        Args:
+            code: 要处理的代码字符串
+
+        Returns:
+            处理后的代码行列表
+        """
+        if not code:
+            return []
+
+        return code.split('\n')
+
+# 避免的做法
+class codeProcessor:  # 类名应该使用CamelCase
+    def __init__(self,config):  # 缺少空格和类型注解
+        self.config=config
+```
+
+### 文档规范
+
+#### 文档字符串
+
+使用Google风格的文档字符串：
+
+```python
+def verify_function(
+    function_name: str,
+    source_code: str,
+    options: Optional[Dict[str, Any]] = None
+) -> VerificationResult:
+    """验证函数的内存安全性。
+
+    Args:
+        function_name: 要验证的函数名
+        source_code: 包含函数的源代码
+        options: 可选的验证选项
+
+    Returns:
+        VerificationResult: 验证结果对象
+
+    Raises:
+        ValueError: 如果函数名或源代码无效
+        VerificationError: 如果验证过程失败
+    """
+    pass
+```
+
+#### 注释规范
+
+```python
+# 好的注释
+def process_data(data: List[str]) -> Dict[str, int]:
+    """处理输入数据并返回统计信息。
+
+    这个函数会去除空行，统计每个单词的出现频率，
+    并返回频率最高的前10个单词。
+    """
+    # 过滤空行和空白字符
+    filtered_data = [line.strip() for line in data if line.strip()]
+
+    # 统计词频
+    word_counts = {}
+    for line in filtered_data:
+        for word in line.split():
+            word_counts[word] = word_counts.get(word, 0) + 1
+
+    return word_counts
+
+# 避免的注释
+def bad_example(data):
+    # 这个函数处理数据
+    result = []  # 初始化结果列表
+    for item in data:  # 遍历数据
+        result.append(item)  # 添加到结果
+    return result  # 返回结果
+```

+## CBMC简介
+
+### 什么是CBMC
+
+CBMC是一个针对C/C++程序的有界模型检查器（Bounded Model Checker），它可以：
+
+- **验证程序属性**: 检查数组越界、空指针解引用、整数溢出等
+- **查找运行时错误**: 内存泄漏、断言失败、除零错误等
+- **生成反例**: 当验证失败时提供具体的反例路径
+- **支持并发**: 验证多线程程序的正确性
+
+### CBMC在CodeDetect中的作用
+
+CodeDetect系统使用CBMC作为核心验证引擎：
+
+```
+C/C++代码 → 解析 → 规范生成 → CBMC验证 → 结果分析
+```
+
+**集成架构**:
+```
+┌─────────────────┐    ┌─────────────────┐    ┌─────────────────┐
+│   CodeDetect    │    │   规范生成      │    │   CBMC引擎      │
+│   解析器        │───▶│   LLM驱动       │───▶│   模型检查      │
+└─────────────────┘    └─────────────────┘    └─────────────────┘
+                                                    │
+                                              ┌─────────────────┐
+                                              │   结果解析      │
+                                              │   错误分析      │
+                                              └─────────────────┘

+
+## 最佳实践
+
+### 代码编写最佳实践
+
+#### 1. 验证友好的代码结构
+
+```c
+// 好的实践：清晰的函数分离
+int validate_input(int value) {
+    if (value < 0 || value > 1000) {
+        return -1;  // 错误值
+    }
+    return 0;  // 成功
+}
+
+int process_data(int data) {
+    // 输入验证
+    if (validate_input(data) != 0) {
+        return -1;
+    }
+
+    // 处理逻辑
+    int result = data * 2;
+
+    // 结果验证
+    if (result < 0) {
+        return -1;  // 溢出检查
+    }
+
+    return result;
+}
+```
+
+#### 2. 边界条件处理
+
+```c
+// 好的实践：边界条件检查
+int array_access(int *array, int size, int index) {
+    // 参数验证
+    if (array == NULL || size <= 0) {
+        return -1;
+    }
+
+    // 边界检查
+    if (index < 0 || index >= size) {
+        return -1;
+    }
+
+    return array[index];
+}
+
+// 好的实践：整数运算安全
+int safe_multiply(int a, int b) {
+    // 检查乘法溢出
+    if (a != 0 && b != 0) {
+        if (a > INT_MAX / b || a < INT_MIN / b) {
+            return -1;  // 溢出
+        }
+    }
+
+    return a * b;
+}
+```
+
+#### 3. 内存安全操作
+
+```c
+// 好的实践：安全的内存操作
+char* safe_string_copy(const char *src, size_t max_len) {
+    if (src == NULL) {
+        return NULL;
+    }
+
+    size_t len = strnlen(src, max_len);

+    }
+
+    strncpy(dest, src, len);
+    dest[len] = '\0';
+
+    return dest;
+}
+
+// 好的实践：资源管理
+void resource_management_example() {
+    FILE *file = fopen("data.txt", "r");
+    if (file == NULL) {
+        return;
+    }
+
+    char *buffer = (char*)malloc(1024);
+    if (buffer == NULL) {
+        fclose(file);
+        return;
+    }
+
+    // 使用资源...
+
+    // 清理资源
+    free(buffer);
+    fclose(file);
+}
+```
+
+### 验证策略最佳实践
+
+#### 1. 渐进式验证
+
+```python
+def progressive_verification(source_file):
+    """渐进式验证策略"""
+
+    # 第一阶段：基本语法和类型检查

+    )
+
+    if basic_result.status != "success":
+        return basic_result
+
+    # 第二阶段：运算和溢出检查
+    overflow_result = run_verification_with_options(
+        source_file,
+        options=["--overflow-check", "--div-by-zero-check"]
+    )

+    if overflow_result.status != "success":
+        return overflow_result
+
+    # 第三阶段：完整验证
+    full_result = run_verification_with_options(
+        source_file,
+        options=[

+
+#### 2. 验证覆盖最大化
+
+```python

+# 嵌入式项目配置
+embedded_project:
+  cbmc:
+    pointer_width: 16
+    endianness: "little"
+    options:
+      - "--16"

+      - "--no-built-in-functions"
+  verification_types:
+    - "memory_safety"
+    - "overflow_detection"
+
+# 安全关键项目配置
+safety_critical:
+  cbmc:
+    timeout: 1800  # 30分钟
+    depth: 50
+    unwind: 25
+    options:
+      - "--bounds-check"

+
+## 模块开发指南
+
+### 新增解析器支持
+
+1. **创建解析器类** (`src/parse/custom_parser.py`):
+```python
+from typing import List, Dict, Any, Optional
+from dataclasses import dataclass
+
+@dataclass
+class CustomParseResult:
+    functions: List[Dict[str, Any]]
+    variables: List[Dict[str, Any]]
+    complexity: Dict[str, Any]
+
+class CustomParser:
+    def __init__(self, config: Optional[Dict] = None):
+        self.config = config or {}
+
+    def parse_file(self, file_path: str) -> CustomParseResult:
+        """实现文件解析逻辑"""
+        pass
+
+    def parse_code(self, code: str, filename: str = "temp.c") -> CustomParseResult:
+        """实现代码字符串解析逻辑"""
+        pass
+
+    def get_supported_extensions(self) -> List[str]:
+        """返回支持的文件扩展名"""
+        return [".c", ".cpp", ".h", ".hpp"]
+```
+
+2. **注册解析器** (`src/parse/__init__.py`):
+```python
+from .custom_parser import CustomParser
+
+PARSER_REGISTRY = {
+    "default": DefaultParser,
+    "custom": CustomParser,
+    # 添加更多解析器
+}
+
+def get_parser(parser_type: str = "default", config: Optional[Dict] = None):
+    """获取指定类型的解析器"""
+    parser_class = PARSER_REGISTRY.get(parser_type, DefaultParser)
+    return parser_class(config)
+```
+
+3. **配置解析器** (`config/default.yaml`):
+```yaml
+parser:
+  type: "custom"  # 使用自定义解析器
+  config:
+    option1: "value1"
+    option2: "value2"
+```
+
+### 新增突变操作符
+
+1. **定义突变类型** (`src/mutate/mutation_types.py`):
+```python
+from enum import Enum
+
+class MutationType(Enum):
+    PREDICATE = "predicate"
+    BOUNDARY = "boundary"
+    ARITHMETIC = "arithmetic"
+    ARRAY = "array"
+    POINTER = "pointer"
+    CUSTOM = "custom"  # 新增自定义类型
+```
+
+2. **实现突变操作符** (`src/mutate/operators.py`):
+```python
+class CBMCMutationOperators:
+    def __init__(self, config: Optional[Dict] = None):
+        self.config = config or {}
+
+    def generate_custom_mutations(
+        self,
+        specification: str,
+        function_metadata: List[Dict]
+    ) -> List[str]:
+        """生成自定义突变"""
+        mutations = []
+
+        # 实现自定义突变逻辑
+        # 例如：修改循环条件
+        import re
+        loop_pattern = r'for\s*\(\s*.*;\s*.*;\s*.*\s*\)'
+        def replace_loop_condition(match):
+            condition = match.group(0)
+            # 修改循环条件
+            return condition.replace('i < n', 'i <= n')
+
+        mutated_spec = re.sub(loop_pattern, replace_loop_condition, specification)
+        if mutated_spec != specification:
+            mutations.append(mutated_spec)
+
+        return mutations
+```
+
+3. **集成到突变引擎** (`src/mutate/engine.py`):
+```python
+class MutationEngine:
+    def generate_mutations(self, specification: str, function_metadata: List[Dict], **kwargs):
+        # ... 现有逻辑
+
+        # 生成自定义突变
+        if MutationType.CUSTOM in mutation_types:
+            custom_mutations = self.operators.generate_custom_mutations(
+                specification, function_metadata
+            )
+            for custom_spec in custom_mutations:
+                mutation = CBMCMutation(
+                    specification=custom_spec,
+                    mutation_type=MutationType.CUSTOM,
+                    confidence=0.8,  # 评估置信度
+                    description="自定义突变描述"
+                )
+                all_mutations.append(mutation)
+```
+
+### 新增验证类型
+
+1. **定义验证类型** (`src/verify/verification_types.py`):
+```python
+from enum import Enum
+
+class VerificationType(Enum):
+    MEMORY_SAFETY = "memory_safety"
+    OVERFLOW_DETECTION = "overflow_detection"
+    POINTER_VALIDITY = "pointer_validity"
+    CONCURRENCY = "concurrency"
+    CUSTOM_TYPE = "custom_type"  # 新增验证类型
+```
+
+2. **实现验证逻辑** (`src/verify/custom_verifier.py`):
+```python
+class CustomVerifier:
+    def __init__(self, config: Optional[Dict] = None):
+        self.config = config or {}
+
+    async def verify_custom_type(
+        self,
+        specification: str,
+        source_file: str,
+        function_metadata: Dict
+    ) -> VerificationResult:
+        """实现自定义验证逻辑"""
+        # 构建验证命令
+        command = self._build_verification_command(
+            specification, source_file, VerificationType.CUSTOM_TYPE
+        )
+
+        # 执行验证
+        result = await self._execute_verification(command)
+
+        # 解析结果
+        parsed_result = self._parse_verification_result(result)
+
+        return parsed_result
+
+    def _build_verification_command(self, specification: str, source_file: str, verification_type: VerificationType) -> List[str]:
+        """构建验证命令"""
+        base_command = ["cbmc", source_file]
+
+        # 添加自定义选项
+        if verification_type == VerificationType.CUSTOM_TYPE:
+            base_command.extend([
+                "--custom-option",
+                "--custom-value"
+            ])
+
+        return base_command
+```
+
+### 新增API端点
+
+1. **定义API路由** (`src/ui/api.py`):
+```python
+from flask import request, jsonify
+from functools import wraps
+
+def require_auth(f):
+    @wraps(f)
+    def decorated(*args, **kwargs):
+        token = request.headers.get('Authorization')
+        if not token or not validate_token(token):
+            return jsonify({"success": False, "error": "Unauthorized"}), 401
+        return f(*args, **kwargs)
+    return decorated
+
+@app.route('/api/custom', methods=['POST'])
+@require_auth
+def handle_custom_operation():
+    """处理自定义操作"""
+    try:
+        data = request.get_json()
+
+        # 验证输入
+        if not data or 'required_field' not in data:
+            return jsonify({
+                "success": False,
+                "error": {
+                    "code": "VALIDATION_ERROR",
+                    "message": "Missing required field"
+                }
+            }), 400
+
+        # 处理业务逻辑
+        result = process_custom_operation(data)
+
+        return jsonify({
+            "success": True,
+            "data": result
+        })
+
+    except Exception as e:
+        logger.error(f"Custom operation failed: {e}")
+        return jsonify({
+            "success": False,
+            "error": {
+                "code": "INTERNAL_ERROR",
+                "message": str(e)
+            }
+        }), 500
+```
+
+2. **添加WebSocket事件** (`src/ui/websocket.py`):
+```python
+@socketio.on('custom_event')
+def handle_custom_event(data):
+    """处理自定义WebSocket事件"""
+    try:
+        # 验证事件数据
+        if not validate_event_data(data):
+            emit('error', {'message': 'Invalid event data'})
+            return
+
+        # 处理事件
+        result = process_custom_event(data)
+
+        # 发送结果
+        emit('custom_result', {
+            'success': True,
+            'data': result
+        })
+
+    except Exception as e:
+        emit('error', {
+            'success': False,
+            'error': str(e)
+        })
+```
+
+---
+
+## 编码规范
+
+### Python编码规范
+
+#### 1. 代码风格
+
+遵循PEP 8规范，使用Black格式化代码：
+
+```python
+# 正确的函数定义
+def process_verification_result(result: VerificationResult) -> Dict[str, Any]:
+    """处理验证结果并返回格式化数据。
+
+    Args:
+        result: 验证结果对象
+
+    Returns:
+        格式化的结果字典
+    """
+    if not result:
+        return {"status": "error", "message": "No result provided"}
+
+    return {
+        "status": result.status,
+        "execution_time": result.execution_time,
+        "memory_used": result.memory_used,
+        "timestamp": datetime.utcnow().isoformat()
+    }
+```
+
+#### 2. 类型注解
+
+所有函数和公共方法都应有类型注解：
+
+```python
+from typing import List, Dict, Any, Optional, Union
+from dataclasses import dataclass
+
+@dataclass
+class FunctionMetadata:
+    name: str
+    return_type: str
+    parameters: List[Parameter]
+    complexity_score: float
+    line_start: int
+    line_end: int
+
+def analyze_function_complexity(
+    metadata: FunctionMetadata,
+    options: Optional[Dict[str, Any]] = None
+) -> float:
+    """分析函数复杂度。
+
+    Args:
+        metadata: 函数元数据
+        options: 分析选项
+
+    Returns:
+        复杂度评分 (0.0-1.0)
+    """
+    options = options or {}
+    # 实现复杂度分析逻辑
+    return calculate_complexity(metadata)
+```
+
+#### 3. 错误处理
+
+使用具体的异常类型和适当的错误消息：
+
+```python
+class ValidationError(Exception):
+    """验证错误"""
+    pass
+
+class ConfigurationError(Exception):
+    """配置错误"""
+    pass
+
+def validate_configuration(config: Dict[str, Any]) -> None:
+    """验证配置参数。
+
+    Args:
+        config: 配置字典
+
+    Raises:
+        ValidationError: 当配置验证失败时
+        ConfigurationError: 当配置格式错误时
+    """
+    if not isinstance(config, dict):
+        raise ConfigurationError("Configuration must be a dictionary")
+
+    required_keys = ['llm', 'cbmc', 'web']
+    for key in required_keys:
+        if key not in config:
+            raise ValidationError(f"Missing required configuration key: {key}")
+
+    # 验证子配置
+    if not isinstance(config.get('llm'), dict):
+        raise ValidationError("LLM configuration must be a dictionary")
+```
+
+#### 4. 日志记录
+
+使用结构化日志记录：
+
+```python
+import logging
+import structlog
+
+# 配置结构化日志
+structlog.configure(
+    processors=[
+        structlog.stdlib.filter_by_level,
+        structlog.stdlib.add_logger_name,
+        structlog.stdlib.add_log_level,
+        structlog.stdlib.PositionalArgumentsFormatter(),
+        structlog.processors.TimeStamper(fmt="iso"),
+        structlog.processors.StackInfoRenderer(),
+        structlog.processors.format_exc_info,
+        structlog.processors.UnicodeDecoder(),
+        structlog.processors.JSONRenderer()
+    ],
+    context_class=dict,
+    logger_factory=structlog.stdlib.LoggerFactory(),
+    wrapper_class=structlog.stdlib.BoundLogger,
+    cache_logger_on_first_use=True,
+)

+logger = structlog.get_logger()
+
+def process_verification_request(request_id: str, data: Dict[str, Any]) -> VerificationResult:
+    """处理验证请求。
+
+    Args:
+        request_id: 请求ID
+        data: 请求数据
+
+    Returns:

+    """
+    logger.info(
+        "Processing verification request",
+        request_id=request_id,
+        function_count=len(data.get('functions', [])),
+        verification_types=data.get('verification_types', [])
+    )
+
+    try:
+        result = perform_verification(data)
+        logger.info(
+            "Verification completed",
+            request_id=request_id,
+            status=result.status,
+            execution_time=result.execution_time
+        )
+        return result
+
+    except Exception as e:
+        logger.error(
+            "Verification failed",
+            request_id=request_id,
+            error=str(e),
+            exc_info=True
+        )
+        raise
+```
+
+### 文档规范
+
+#### 1. 模块文档
+
+每个模块都应有详细的文档字符串：
+
+```python
+"""

+
+## 测试指南
+
+### 测试框架
+
+使用pytest作为主要测试框架：
+
+```bash
+# 运行所有测试
+pytest
+
+# 运行特定测试文件
+pytest tests/unit/test_mutate.py
+
+# 运行特定测试类
+pytest tests/unit/test_mutate.py::TestMutationEngine
+
+# 运行特定测试方法
+pytest tests/unit/test_mutate.py::TestMutationEngine::test_generate_mutations_basic
+
+# 生成覆盖率报告
+pytest --cov=src --cov-report=html --cov-report=term
+
+# 并行运行测试
+pytest -n auto  # 需要pytest-xdist插件
+```
+
+### 测试分类
+
+#### 1. 单元测试
+
+测试单个函数或类的功能：
+
+```python
+def test_function_isolation(self):
+    """测试函数的独立功能"""
+    # 准备测试数据
+    input_data = {"key": "value"}
+
+    # 调用被测试函数
+    result = function_to_test(input_data)
+
+    # 验证结果
+    assert result == expected_result
+```
+
+#### 2. 集成测试
+
+测试模块间的交互：
+
+```python
+def test_complete_pipeline(self):
+    """测试完整的验证管道"""
+    # 准备测试文件
+    with tempfile.NamedTemporaryFile(mode='w', suffix='.c', delete=False) as f:
+        f.write(test_code)
+        temp_file = f.name
+
+    try:
+        # 运行完整管道
+        result = run_verification_pipeline(temp_file)
+
+        # 验证管道结果
+        assert result['success'] is True
+        assert 'verifications' in result
+        assert len(result['verifications']) > 0
+
+    finally:
+        os.unlink(temp_file)
+```
+
+#### 3. 性能测试
+
+测试系统性能特征：
+
+```python
+def test_response_time(self):
+    """测试API响应时间"""
+    start_time = time.time()
+
+    # 执行操作
+    result = api_call()
+
+    end_time = time.time()
+    response_time = end_time - start_time
+
+    # 验证性能要求
+    assert response_time < 1.0, f"响应时间 {response_time:.2f}s 过长"
+```
+
+### Mock和Stub
+
+使用unittest.mock创建测试替身：
+
+```python
+from unittest.mock import Mock, AsyncMock, patch
+
+def test_with_mock_llm(self):
+    """使用Mock的LLM服务测试"""
+    with patch('src.mutate.engine.LLMService') as mock_llm:
+        # 设置Mock行为
+        mock_llm.return_value.generate_spec.return_value = "mocked_spec"
+
+        # 运行测试
+        result = mutation_engine.generate_spec(function_metadata)
+
+        # 验证Mock被正确调用
+        mock_llm.return_value.generate_spec.assert_called_once()
+        assert result == "mocked_spec"
+
+def test_async_with_mock(self):
+    """测试异步函数的Mock"""
+    async def test_async_operation():
+        with patch('src.verify.cbmc_runner.CBMCRunner') as mock_runner:
+            # 设置异步Mock
+            mock_runner.return_value.run_verification.return_value = AsyncMock(
+                return_value=mock_verification_result
+            )
+
+            # 运行异步测试
+            result = await runner.run_verification(
+                function_metadata, source_file, specification
+            )
+
+            # 验证结果
+            assert result.status == "success"
+```
+
+### 测试数据管理
+
+#### 1. 测试固件
+
+使用pytest fixture管理测试数据：
+
+```python
+@pytest.fixture
+def sample_c_code(self):
+    """示例C代码"""
+    return """
+    int add(int a, int b) {
+        return a + b;
+    }
+    """
+
+@pytest.fixture
+def sample_function_metadata(self):
+    """示例函数元数据"""
+    return {
+        "name": "add",
+        "return_type": "int",
+        "parameters": [
+            {"name": "a", "type": "int"},
+            {"name": "b", "type": "int"}
+        ],
+        "complexity_score": 0.2
+    }
+
+@pytest.fixture
+def temporary_c_file(self, sample_c_code):
+    """临时C文件"""
+    with tempfile.NamedTemporaryFile(mode='w', suffix='.c', delete=False) as f:
+        f.write(sample_c_code)
+        temp_file = f.name
+
+    yield temp_file
+
+    # 清理
+    os.unlink(temp_file)
+```
+
+#### 2. 参数化测试
+
+使用参数化测试减少代码重复：
+
+```python
+@pytest.mark.parametrize("input_code,expected_functions", [
+    ("int f() { return 0; }", ["f"]),
+    ("int f() { return 0; } int g() { return 1; }", ["f", "g"]),
+    ("", []),  # 空代码
+])
+def test_function_extraction(self, input_code, expected_functions):
+    """参数化测试函数提取"""
+    parser = CodeParser()
+    result = parser.parse_code(input_code)
+
+    actual_functions = [f.name for f in result.functions]
+    assert actual_functions == expected_functions
+```
+
+---
+
+## 调试指南
+
+### 日志调试
+
+#### 1. 配置调试日志
+
+```python
+import logging
+
+# 设置调试级别日志
+logging.basicConfig(
+    level=logging.DEBUG,
+    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
+)
+
+logger = logging.getLogger(__name__)
+
+def debug_function_call(func):
+    """装饰器：记录函数调用"""
+    @functools.wraps(func)
+    def wrapper(*args, **kwargs):
+        logger.debug(f"调用 {func.__name__}: args={args}, kwargs={kwargs}")
+        result = func(*args, **kwargs)
+        logger.debug(f"{func.__name__} 返回: {result}")
+        return result
+    return wrapper
+
+@debug_function_call
+def process_data(data):
+    """处理数据函数"""
+    return data * 2
+```
+
+#### 2. 使用调试器
+
+```python
+import pdb
+
+def debug_complex_function(data):
+    """复杂函数调试"""
+    result = []
+
+    for item in data:
+        # 设置断点
+        if len(result) > 5:
+            pdb.set_trace()  # 手动断点
+
+        processed_item = item * 2
+        result.append(processed_item)
+
+    return result
+```
+
+### 性能调试
+
+#### 1. 性能分析
+
+```python
+import cProfile
+import pstats
+
+def profile_function():
+    """性能分析函数"""
+    profiler = cProfile.Profile()
+    profiler.enable()
+
+    # 运行要分析的代码
+    result = run_verification_pipeline("test.c")
+
+    profiler.disable()
+    stats = pstats.Stats(profiler).sort_stats('cumulative')
+    stats.print_stats(10)  # 显示前10个最耗时的函数
+
+    return result
+```
+
+#### 2. 内存调试
+
+```python
+import tracemalloc
+
+def debug_memory_usage():
+    """内存使用调试"""
+    # 开始内存跟踪
+    tracemalloc.start()
+
+    # 运行代码
+    result = memory_intensive_operation()
+
+    # 获取内存快照
+    snapshot1 = tracemalloc.take_snapshot()
+    snapshot2 = tracemalloc.take_snapshot()
+
+    # 比较快照
+    top_stats = snapshot2.compare_to(snapshot1, 'lineno')
+    print("[ Top 10 内存增长位置 ]")
+    for stat in top_stats[:10]:
+        print(stat)
+
+    tracemalloc.stop()
+    return result
+```
+
+### 远程调试
+
+#### 1. 配置远程调试
+
+```python
+import debugpy
+
+def enable_remote_debug():
+    """启用远程调试"""
+    debugpy.listen(5678)  # 监听端口
+    print("等待调试器连接...")
+    debugpy.wait_for_client()  # 等待调试器连接
+    print("调试器已连接")
+
+# 在应用启动时调用
+if os.getenv('DEBUG_MODE') == 'true':
+    enable_remote_debug()
+```
+
+#### 2. VS Code远程调试配置
+
+```json
+{
+    "version": "0.2.0",
+    "configurations": [
+        {
+            "name": "Python: Remote Debug",
+            "type": "python",
+            "request": "attach",
+            "connect": {
+                "host": "localhost",
+                "port": 5678
+            },
+            "pathMappings": [
+                {
+                    "localRoot": "${workspaceFolder}",
+                    "remoteRoot": "."
+                }
+            ]
+        }
+    ]
+}
+```
+
+---
+
+## 性能优化
+
+### 代码优化
+
+#### 1. 算法优化
+
+```python
+# 优化前：O(n²) 复杂度
+def find_duplicates_slow(items):
+    """查找重复项（慢版本）"""
+    duplicates = []
+    for i, item1 in enumerate(items):
+        for j, item2 in enumerate(items):
+            if i != j and item1 == item2:
+                duplicates.append(item1)
+    return duplicates
+
+# 优化后：O(n) 复杂度
+def find_duplicates_fast(items):
+    """查找重复项（快版本）"""
+    seen = set()
+    duplicates = []
+    for item in items:
+        if item in seen and item not in duplicates:
+            duplicates.append(item)
+        seen.add(item)
+    return duplicates
+```
+
+#### 2. 缓存优化
+
+```python
+from functools import lru_cache
+import hashlib
+
+# 使用LRU缓存
+@lru_cache(maxsize=1000)
+def expensive_computation(input_data):
+    """昂贵的计算函数"""
+    result = complex_calculation(input_data)
+    return result
+
+# 自定义缓存
+class ComputationCache:
+    def __init__(self, max_size=1000):
+        self.cache = {}
+        self.max_size = max_size
+
+    def get(self, key):
+        return self.cache.get(key)
+
+    def set(self, key, value):
+        if len(self.cache) >= self.max_size:
+            # 移除最旧的条目
+            oldest_key = next(iter(self.cache))
+            del self.cache[oldest_key]
+        self.cache[key] = value
+
+    def compute(self, input_data):
+        """带缓存的计算"""
+        cache_key = hashlib.md5(str(input_data).encode()).hexdigest()
+        cached_result = self.get(cache_key)
+
+        if cached_result is not None:
+            return cached_result
+
+        result = expensive_computation(input_data)
+        self.set(cache_key, result)
+        return result
+```
+
+### 并发优化
+
+#### 1. 异步I/O
+
+```python
+import asyncio
+import aiohttp
+
+# 同步版本（慢）
+def fetch_urls_sync(urls):
+    """同步获取URL内容"""
+    results = []
+    for url in urls:
+        response = requests.get(url)
+        results.append(response.json())
+    return results
+
+# 异步版本（快）
+async def fetch_urls_async(urls):
+    """异步获取URL内容"""
+    async with aiohttp.ClientSession() as session:
+        tasks = [fetch_single_url(session, url) for url in urls]
+        results = await asyncio.gather(*tasks)
+    return results
+
+async def fetch_single_url(session, url):
+    """获取单个URL"""
+    async with session.get(url) as response:
+        return await response.json()
+```
+
+#### 2. 线程池优化
+
+```python
+from concurrent.futures import ThreadPoolExecutor, as_completed
+
+def parallel_processing(items, max_workers=4):
+    """并行处理"""
+    with ThreadPoolExecutor(max_workers=max_workers) as executor:
+        # 提交所有任务
+        futures = [executor.submit(process_item, item) for item in items]
+
+        # 收集结果
+        results = []
+        for future in as_completed(futures):
+            try:
+                result = future.result()
+                results.append(result)
+            except Exception as e:
+                logger.error(f"处理失败: {e}")
+
+    return results
+```
+
+### 内存优化
+
+#### 1. 生成器使用
+
+```python
+# 内存密集型版本
+def process_large_file_list(file_paths):
+    """处理大文件列表（内存密集）"""
+    results = []
+    for file_path in file_paths:
+        data = read_large_file(file_path)
+        processed_data = process_data(data)
+        results.append(processed_data)
+    return results  # 一次性返回所有结果
+
+# 内存友好版本
+def process_large_file_generator(file_paths):
+    """处理大文件列表（生成器）"""
+    for file_path in file_paths:
+        data = read_large_file(file_path)
+        processed_data = process_data(data)
+        yield processed_data  # 逐个生成结果
+
+# 使用生成器
+for result in process_large_file_generator(large_file_list):
+    # 每次只处理一个结果
+    handle_result(result)
+```
+
+#### 2. 对象池模式
+
+```python
+class ObjectPool:
+    """对象池模式"""
+    def __init__(self, creator_func, max_size=10):
+        self.creator_func = creator_func
+        self.max_size = max_size
+        self.pool = []
+        self.lock = threading.Lock()
+
+    def get(self):
+        """获取对象"""
+        with self.lock:
+            if self.pool:
+                return self.pool.pop()
+            return self.creator_func()
+
+    def put(self, obj):
+        """归还对象"""
+        with self.lock:
+            if len(self.pool) < self.max_size:
+                # 重置对象状态
+                if hasattr(obj, 'reset'):
+                    obj.reset()
+                self.pool.append(obj)
+
+# 使用对象池
+connection_pool = ObjectPool(create_db_connection, max_size=5)
+
+def database_operation():
+    """数据库操作"""
+    conn = connection_pool.get()
+    try:
+        result = execute_query(conn, "SELECT * FROM table")
+        return result
+    finally:
+        connection_pool.put(conn)
+```
+

+# CodeDetect基础使用教程
+
+## 概述
+
+本教程将指导您完成CodeDetect的基础使用，从安装配置到运行第一次代码验证。
+
+## 前提条件
+
+- Python 3.8或更高版本
+- CBMC (C Bounded Model Checker) 安装
+- 基本的C语言知识
+
+## 第一步：安装
+
+### 1.1 克隆仓库
+
+```bash
+git clone https://github.com/your-username/codedetect.git
+cd codedetect
+```
+
+### 1.2 安装Python依赖
+
+```bash
+pip install -r requirements.txt
+pip install -r requirements-dev.txt
+```
+
+### 1.3 安装CBMC
+
+**Ubuntu/Debian:**
+```bash
+sudo apt-get update
+sudo apt-get install cbmc
+```
+
+**macOS:**
+```bash
+brew install cbmc
+```
+
+### 1.4 验证安装
+
+```bash
+# 检查CBMC安装
+cbmc --version
+
+# 检查Python依赖
+python -m pytest tests/unit/ -v
+```
+
+## 第二步：基本使用
+
+### 2.1 准备测试代码
+
+创建一个简单的C文件 `test_function.c`：
+
+```c
+int add(int a, int b) {
+    return a + b;
+}
+```
+
+### 2.2 使用命令行界面
+
+```bash
+# 运行代码验证
+python -m src.main verify test_function.c
+
+# 生成规范
+python -m src.main generate-spec test_function.c --function add
+
+# 运行完整分析
+python -m src.main analyze test_function.c
+```
+
+### 2.3 使用Web界面
+
+启动Web服务器：
+
+```bash
+python -m src.ui.web_app
+```
+
+然后在浏览器中访问 `http://localhost:5000`
+
+## 第三步：验证结果解读
+
+### 3.1 成功验证
+
+```
+VERIFICATION SUCCESSFUL
+Property __CPROVER_assert: OK
+Property __CPROVER_assert: OK
+
+** 1 of 1 properties verified (2 PASS) **
+```
+
+**含义：**
+- 所有属性都已验证通过
+- 代码在给定条件下是安全的
+
+### 3.2 验证失败
+
+```
+VERIFICATION FAILED
+Property __CPROVER_assert: FAILED
+
+Violated property:
+  File test.c, line 2
+  assertion
+  arr[index]
+
+STATE:
+  - Line 2: arr[index]
+  - index: 5
+  - size: 3
+```
+
+**含义：**
+- 发现了潜在的安全问题
+- 需要修复代码或添加保护措施
+
+## 第四步：进阶功能
+
+### 4.1 使用突变测试
+
+```bash
+# 生成测试突变
+python -m src.main mutate test_function.c --function add
+
+# 运行突变验证
+python -m src.main verify-mutants test_function.c
+```
+
+### 4.2 批量处理
+
+```bash
+# 处理整个目录
+python -m src.main batch-verify ./src/
+
+# 生成报告
+python -m src.main generate-report --format html
+```
+
+### 4.3 配置文件
+
+创建配置文件 `config.yaml`：
+
+```yaml
+verification:
+  cbmc:
+    options:
+      - "--bounds-check"
+      - "--pointer-check"
+      - "--unwind 10"
+    timeout: 30
+
+  generation:
+    llm:
+      model: "gpt-4"
+      temperature: 0.3
+      max_tokens: 1000
+```
+
+## 第五步：故障排除
+
+### 5.1 常见问题
+
+**CBMC未找到：**
+```bash
+# 确保CBMC在PATH中
+which cbmc
+
+# 如果没有，手动设置
+export CBMC_PATH=/path/to/cbmc
+```
+
+**Python依赖问题：**
+```bash
+# 重新安装依赖
+pip install --force-reinstall -r requirements.txt
+```
+
+**内存不足：**
+```bash
+# 减少验证深度
+python -m src.main verify test.c --unwind 5
+```
+
+### 5.2 性能优化
+
+- 使用 `--unwind` 限制递归深度
+- 增加 `--timeout` 防止长时间运行
+- 使用 `--jobs` 进行并行处理
+
+## 第六步：最佳实践
+
+### 6.1 编写可验证的代码
+
+```c
+// 好的实践：包含边界检查
+int safe_access(int* arr, int size, int index) {
+    if (arr == NULL || size <= 0 || index < 0 || index >= size) {
+        return 0;
+    }
+    return arr[index];
+}
+
+// 避免的做法：没有边界检查
+int unsafe_access(int* arr, int size, int index) {
+    return arr[index]; // 潜在的缓冲区溢出
+}
+```
+
+### 6.2 规范编写建议
+
+- 使用清晰的断言
+- 考虑边界条件
+- 添加前置条件
+- 记录假设条件
+
+### 6.3 持续集成
+
+将CodeDetect集成到CI/CD流程中：
+
+```yaml
+# .github/workflows/verify.yml
+name: Code Verification
+on: [push, pull_request]
+
+jobs:
+  verify:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+      - name: Setup Python
+        uses: actions/setup-python@v2
+        with:
+          python-version: 3.9
+      - name: Install dependencies
+        run: |
+          pip install -r requirements.txt
+          sudo apt-get install cbmc
+      - name: Run verification
+        run: python -m pytest tests/ -v
+```

+# CodeDetect FreeRTOS验证教程
+
+## 概述
+
+本教程专门介绍如何使用CodeDetect验证FreeRTOS应用程序的内存安全和并发正确性。
+
+## 前提条件
+
+- 完成基础使用教程
+- FreeRTOS开发经验
+- 并发编程基础
+
+## 第一步：FreeRTOS环境设置
+
+### 1.1 安装FreeRTOS
+
+```bash
+# 使用我们的设置脚本
+./scripts/setup-freertos-example.sh
+
+# 或者手动安装
+git clone https://github.com/FreeRTOS/FreeRTOS.git
+export FREERTOS_PATH=/path/to/FreeRTOS
+```
+
+### 1.2 验证FreeRTOS安装
+
+```bash
+# 检查FreeRTOS头文件
+ls $FREERTOS_PATH/FreeRTOS/Source/include/
+
+# 编译示例
+cd examples/freertos
+make
+```
+
+## 第二步：基本FreeRTOS验证
+
+### 2.1 任务创建验证
+
+考虑以下FreeRTOS任务代码：
+
+```c
+#include "FreeRTOS.h"
+#include "task.h"
+
+typedef struct {
+    int task_id;
+    char* name;
+} TaskParameters_t;
+
+void vCounterTask(void *pvParameters) {
+    TaskParameters_t *params = (TaskParameters_t *)pvParameters;
+
+    // 参数验证
+    configASSERT(params != NULL);
+    configASSERT(params->task_id > 0);
+
+    while (1) {
+        // 安全的任务逻辑
+        vTaskDelay(pdMS_TO_TICKS(1000));
+    }
+}
+```
+
+使用CodeDetect验证：
+
+```bash
+# 生成任务规范
+python -m src.main generate-spec task_verification_example.c \
+    --function vCounterTask \
+    --framework freertos
+
+# 运行验证
+python -m src.main verify task_verification_example.c \
+    --function vCounterTask \
+    --include-path $FREERTOS_PATH/FreeRTOS/Source/include
+```
+
+### 2.2 解读验证结果
+
+**成功验证输出：**
+```
+VERIFICATION SUCCESSFUL
+Property __CPROVER_assert: OK (parameter validation)
+Property __CPROVER_assert: OK (null pointer check)
+Property __CPROVER_assert: OK (task safety)
+```
+
+**常见问题：**
+```
+VERIFICATION FAILED
+Property __CPROVER_assert: FAILED
+Violated property: parameter validation
+```
+
+## 第三步：队列操作验证
+
+### 3.1 生产者-消费者模式
+
+```c
+#include "FreeRTOS.h"
+#include "queue.h"
+
+typedef struct {
+    int id;
+    int value;
+    int is_critical;
+} Message_t;
+
+QueueHandle_t xMessageQueue;
+
+void vProducerTask(void *pvParameters) {
+    Message_t xMessage;
+
+    while (1) {
+        xMessage.id++;
+        xMessage.value = xMessage.id * 10;
+        xMessage.is_critical = (xMessage.id % 10 == 0);
+
+        if (xMessage.is_critical) {
+            // 临界消息处理
+            BaseType_t xSendResult = xQueueSend(xMessageQueue, &xMessage, pdMS_TO_TICKS(100));
+            configASSERT(xSendResult == pdPASS);
+        } else {
+            xQueueSend(xMessageQueue, &xMessage, 0);
+        }
+
+        vTaskDelay(pdMS_TO_TICKS(10));
+    }
+}
+
+void vConsumerTask(void *pvParameters) {
+    Message_t xReceivedMessage;
+
+    while (1) {
+        if (xQueueReceive(xMessageQueue, &xReceivedMessage, pdMS_TO_TICKS(100)) == pdPASS) {
+            // 安全处理接收到的消息
+            configASSERT(xReceivedMessage.value >= 0);
+        }
+    }
+}
+```
+
+### 3.2 验证队列安全性
+
+```bash
+# 验证生产者任务
+python -m src.main verify queue_verification_example.c \
+    --function vProducerTask \
+    --framework freertos \
+    --verify-concurrency
+
+# 验证消费者任务
+python -m src.main verify queue_verification_example.c \
+    --function vConsumerTask \
+    --framework freertos \
+    --verify-concurrency
+
+# 验证队列创建
+python -m src.main verify queue_verification_example.c \
+    --function main \
+    --framework freertos
+```
+
+## 第四步：信号量和互斥量验证
+
+### 4.1 资源保护模式
+
+```c
+#include "FreeRTOS.h"
+#include "semphr.h"
+
+SemaphoreHandle_t xResourceSemaphore;
+int shared_resource = 0;
+
+void vResourceUserTask(void *pvParameters) {
+    while (1) {
+        // 安全地获取资源
+        if (xSemaphoreTake(xResourceSemaphore, pdMS_TO_TICKS(100)) == pdTRUE) {
+            // 临界区开始
+            shared_resource++;
+            configASSERT(shared_resource > 0);
+
+            // 模拟处理时间
+            vTaskDelay(pdMS_TO_TICKS(10));
+
+            // 释放资源
+            xSemaphoreGive(xResourceSemaphore);
+        }
+
+        vTaskDelay(pdMS_TO_TICKS(50));
+    }
+}
+```
+
+### 4.2 验证互斥访问
+
+```bash
+# 验证资源使用
+python -m src.main verify semaphore_example.c \
+    --function vResourceUserTask \
+    --framework freertos \
+    --verify-deadlock
+
+# 检查死锁可能性
+python -m src.main analyze-deadlocks semaphore_example.c
+```
+
+## 第五步：中断处理验证
+
+### 5.1 中断服务例程
+
+```c
+#include "FreeRTOS.h"
+#include "task.h"
+#include "queue.h"
+
+QueueHandle_t xInterruptQueue;
+
+void vExternalInterruptHandler(void) {
+    BaseType_t xHigherPriorityTaskWoken = pdFALSE;
+    uint32_t interrupt_status = 0;
+
+    // 安全的中断处理
+    taskENTER_CRITICAL_FROM_ISR();
+    interrupt_status = read_interrupt_register();
+    taskEXIT_CRITICAL_FROM_ISR();
+
+    // 发送消息到任务
+    xQueueSendFromISR(xInterruptQueue, &interrupt_status, &xHigherPriorityTaskWoken);
+
+    portYIELD_FROM_ISR(xHigherPriorityTaskWoken);
+}
+```
+
+### 5.2 验证中断安全性
+
+```bash
+# 验证中断处理
+python -m src.main verify interrupt_example.c \
+    --function vExternalInterruptHandler \
+    --framework freertos \
+    --verify-interrupt-safety
+```
+
+## 第六步：系统级验证
+
+### 6.1 完整系统验证
+
+```bash
+# 验证整个FreeRTOS应用程序
+python -m src.main batch-verify ./freertos_app/ \
+    --framework freertos \
+    --include-path $FREERTOS_PATH/FreeRTOS/Source/include \
+    --verify-concurrency \
+    --verify-deadlock \
+    --verify-memory-safety
+
+# 生成系统级报告
+python -m src.main generate-system-report ./freertos_app/ \
+    --format html \
+    --include-concurrency-analysis
+```
+
+### 6.2 性能分析
+
+```bash
+# 分析任务调度
+python -m src.main analyze-scheduling freertos_app.c
+
+# 检查资源使用
+python -m src.main analyze-resource-usage freertos_app.c
+```
+
+## 第七步：故障排除
+
+### 7.1 常见FreeRTOS验证问题
+
+**FreeRTOS头文件未找到：**
+```bash
+# 设置正确的包含路径
+export FREERTOS_INCLUDE_PATH=$FREERTOS_PATH/FreeRTOS/Source/include:$FREERTOS_PATH/FreeRTOS-Plus/Source/FreeRTOS-Plus-CLI/include
+
+# 验证命令
+python -m src.main verify test.c --include-path $FREERTOS_INCLUDE_PATH
+```
+
+**并发验证超时：**
+```bash
+# 减少验证深度
+python -m src.main verify test.c --unwind 5 --concurrency-depth 3
+
+# 增加超时时间
+python -m src.main verify test.c --timeout 120
+```
+
+**内存模型问题：**
+```bash
+# 使用简化的内存模型
+python -m src.main verify test.c --memory-model simple
+
+# 禁用某些检查
+python -m src.main verify test.c --no-pointer-check
+```
+
+### 7.2 FreeRTOS特定配置
+
+创建FreeRTOS配置文件 `freertos_config.yaml`：
+
+```yaml
+freertos:
+  include_paths:
+    - "$FREERTOS_PATH/FreeRTOS/Source/include"
+    - "$FREERTOS_PATH/FreeRTOS/Plus/Source/FreeRTOS-Plus-CLI/include"
+
+  verification:
+    max_tasks: 10
+    max_queues: 5
+    max_semaphores: 5
+    max_interrupts: 3
+
+  analysis:
+    check_deadlocks: true
+    check_priority_inversion: true
+    check_stack_overflow: true
+    check_resource_leaks: true
+
+  memory_model:
+    heap_size: 1024
+    stack_size: 128
+    configASSERT: true
+```
+
+## 第八步：最佳实践
+
+### 8.1 FreeRTOS安全编程
+
+```c
+// 好的实践：安全的任务创建
+TaskHandle_t xTaskHandle = NULL;
+BaseType_t xResult = xTaskCreate(
+    vTaskFunction,
+    "TaskName",
+    configMINIMAL_STACK_SIZE,
+    pvParameters,
+    tskIDLE_PRIORITY + 1,
+    &xTaskHandle
+);
+configASSERT(xResult == pdPASS);
+
+// 避免的做法：不检查创建结果
+xTaskCreate(vTaskFunction, "TaskName", 128, pvParameters, 1, NULL);
+```
+
+### 8.2 队列安全使用
+
+```c
+// 好的实践：安全的队列操作
+BaseType_t xResult = xQueueSend(xQueue, &data, pdMS_TO_TICKS(100));
+if (xResult != pdPASS) {
+    // 处理队列满的情况
+}
+
+// 避免的做法：不检查返回值
+xQueueSend(xQueue, &data, portMAX_DELAY);
+```
+
+### 8.3 中断安全设计
+
+```c
+// 好的实践：中断安全
+void vInterruptHandler(void) {
+    uint32_t status;
+
+    taskENTER_CRITICAL_FROM_ISR();
+    status = read_register();
+    taskEXIT_CRITICAL_FROM_ISR();
+
+    // 快速处理并返回
+}
+
+// 避免的做法：在中断中执行耗时操作
+void vBadInterruptHandler(void) {
+    // 长时间处理
+    for (int i = 0; i < 1000; i++) {
+        complex_operation();
+    }
+}
+```

+    return a + b;
+}
+EOF
+
+# 测试CBMC基本功能
+cbmc test.c --function add --show-properties
+```
+
+## 第一个验证示例
+
+### 创建C代码文件
+
+```bash
+# 创建示例代码目录
+mkdir examples && cd examples
+
+# 创建简单的加法函数
+cat > add_function.c << 'EOF'
+/**
+ * 简单的加法函数
+ * @param a 第一个整数
+ * @param b 第二个整数
+ * @return 两数之和
+ */
+int add(int a, int b) {
+    return a + b;
+}
+EOF
+```
+
+### 使用命令行工具
+
+```bash
+# 返回项目根目录
+cd ../../
+
+# 使用CodeDetect CLI进行验证
+python -m src.cli.main --file examples/add_function.c --function add
+
+# 或者使用测试运行脚本
+chmod +x scripts/run_tests.sh
+./scripts/run_tests.sh --module=verify --verbose
+```
+
+### 预期输出
+
+```
+🚀 CodeDetect CLI
+================
+📁 正在解析文件: examples/add_function.c

+✅ 验证成功!
+📊 结果摘要:
+- 状态: 成功
+- 执行时间: 0.45s
+- 验证属性: 3
+- 通过属性: 3
+- 失败属性: 0
+```
+
+### 理解验证结果
+
+CodeDetect会自动生成CBMC验证规范，包括：
+
+1. **输入约束**: 限制输入参数范围以防止溢出
+2. **基本正确性**: 验证函数返回预期结果
+3. **边界检查**: 验证边界条件下的行为
+
+生成的规范大致如下：
+
+```c
+void add_test() {
+    int a = __CPROVER_nondet_int();
+    int b = __CPROVER_nondet_int();
+
+    // 添加合理的边界约束
+    __CPROVER_assume(a >= -1000 && a <= 1000);
+    __CPROVER_assume(b >= -1000 && b <= 1000);
+
+    int result = add(a, b);
+
+    // 验证基本正确性
+    __CPROVER_assert(result == a + b, "addition_correct");
+
+    // 验证溢出检查
+    if (a > 0 && b > 0) {
+        __CPROVER_assert(result > a, "no_positive_overflow");
+    }
+    if (a < 0 && b < 0) {
+        __CPROVER_assert(result < a, "no_negative_overflow");
+    }
+}
+```
+

+# FreeRTOS验证示例
+
+本目录包含使用CodeDetect系统验证FreeRTOS代码的完整示例。这些示例展示了如何在实时操作系统环境中进行形式化验证，包括任务管理、队列操作、同步机制和中断处理。
+
+## 示例概览
+
+### 1. 任务验证示例 (`task_verification_example.c`)
+
+**文件**: `task_verification_example.c`
+
+**功能**: 演示FreeRTOS任务的创建、管理和验证
+
+**验证要点**:
+- 任务参数验证（NULL指针检查）
+- 任务生命周期管理
+- 栈空间使用验证
+- 任务同步机制
+- 内存安全性验证
+- 任务状态一致性
+
+**关键代码片段**:
+```c
+void vCounterTask(void *pvParameters) {
+    TaskParameters_t *params = (TaskParameters_t *)pvParameters;
+
+    /* 参数验证 - CodeDetect将生成相应的CBMC规范 */
+    configASSERT(params != NULL);
+    configASSERT(params->task_id > 0);
+    configASSERT(params->max_count > 0);
+
+    /* 任务循环 */
+    while (params->should_stop == pdFALSE) {
+        /* 边界检查 - 防止计数器溢出 */
+        if (params->counter < params->max_count) {
+            params->counter++;
+        }
+        vTaskDelay(pdMS_TO_TICKS(100));
+    }
+}
+```
+
+### 2. 队列验证示例 (`queue_verification_example.c`)
+
+**文件**: `queue_verification_example.c`
+
+**功能**: 演示FreeRTOS队列操作的验证
+
+**验证要点**:
+- 队列创建和删除的安全性
+- 队列满和空状态的处理
+- 生产者-消费者模式验证
+- 并发访问安全性
+- 消息完整性检查
+- 队列溢出保护
+
+**关键代码片段**:
+```c
+void vProducerTask(void *pvParameters) {
+    if (xMessage.is_critical) {
+        /* 关键消息使用更长等待时间 */
+        xSendResult = xQueueSend(xMessageQueue, &xMessage, pdMS_TO_TICKS(100));
+    } else {
+        /* 普通消息使用较短等待时间 */
+        xSendResult = xQueueSend(xMessageQueue, &xMessage, pdMS_TO_TICKS(10));
+    }
+
+    /* 错误处理 */
+    if (xSendResult != pdPASS) {
+        xQueueStats.queue_full_errors++;
+    }
+}
+```
+
+## 验证模式
+
+### 1. 基本验证
+
+**目标**: 验证代码的基本正确性
+- 内存安全
+- 空指针处理
+- 边界条件
+- 资源管理
+
+**CBMC规范生成**:
+```c
+void test_task_safety() {
+    TaskParameters_t params;
+    vCounterTask(&params);
+    __CPROVER_assert(params.counter >= 0, "counter_non_negative");
+}
+```
+
+### 2. 并发验证
+
+**目标**: 验证多任务环境下的安全性
+- 竞态条件检测
+- 死锁预防
+- 数据一致性
+- 同步机制验证
+
+**CBMC规范生成**:
+```c
+void test_concurrent_access() {
+    QueueHandle_t queue = xQueueCreate(10, sizeof(int));
+    /* CodeDetect生成并发访问验证规范 */
+    __CPROVER_assert(queue != NULL, "queue_creation_success");
+}
+```
+
+### 3. 性能验证
+
+**目标**: 验证实时性能要求
+- 响应时间保证
+- 内存使用限制
+- 执行时间分析
+- 资源使用效率
+
+## CodeDetect集成
+
+### 1. 配置文件
+
+创建 `freertos_config.yaml`:
+```yaml
+freertos:
+  include_headers:
+    - "FreeRTOS.h"
+    - "task.h"
+    - "queue.h"
+    - "semphr.h"
+  config_path: "/path/to/FreeRTOSConfig.h"
+  heap_size: 4096
+  max_tasks: 10
+  stack_size: 1024
+
+verification:
+  target_types: ["memory_safety", "concurrency", "overflow_detection"]
+  timeout: 300
+  max_concurrent_jobs: 4
+```
+
+### 2. 验证流程
+
+1. **代码解析**: 分析FreeRTOS代码结构
+2. **规范生成**: 基于LLM生成CBMC验证规范
+3. **规范突变**: 生成变异规范提高覆盖率
+4. **CBMC验证**: 运行形式化验证
+5. **结果分析**: 生成详细验证报告
+
+### 3. API使用示例
+
+```python
+from src.verify.cbmc_runner import CBMCRunner
+from src.mutate.engine import MutationEngine
+
+# 创建验证器
+runner = CBMCRunner()
+engine = MutationEngine()
+
+# 解析FreeRTOS代码
+metadata = parse_freertos_code("task_example.c")
+
+# 生成验证规范
+specifications = generate_freertos_specs(metadata)
+
+# 生成突变规范
+mutations = engine.generate_mutations(
+    specifications[0],
+    metadata,
+    max_mutations=10
+)
+
+# 运行验证
+results = []
+for mutation in mutations:
+    result = await runner.run_verification(
+        function_metadata=metadata[0],
+        source_file="task_example.c",
+        specification=mutation.specification
+    )
+    results.append(result)
+```
+
+## 验证报告
+
+### 典型验证结果
+
+```
+=== FreeRTOS任务验证报告 ===
+
+文件: task_verification_example.c
+函数: vCounterTask
+验证时间: 2.34s
+
+✅ 内存安全: 通过
+  - 无空指针解引用
+  - 无缓冲区溢出
+  - 无内存泄漏
+
+✅ 并发安全: 通过
+  - 任务同步正确
+  - 无数据竞争
+  - 栈空间充足
+
+✅ 边界检查: 通过

+  - 栈使用率较高 (85%)
+
+建议:
+1. 考虑减少任务延时以提高响应性
+2. 增加栈大小或优化内存使用
+```
+
+## 高级验证场景
+
+### 1. 中断处理验证
+
+```c
+void vISR_Handler(void) {
+    BaseType_t xHigherPriorityTaskWoken = pdFALSE;
+
+    /* 中断安全的关键区域 */
+    taskENTER_CRITICAL_FROM_ISR();
+
+    /* 处理中断 */
+    xQueueSendFromISR(xQueue, &data, &xHigherPriorityTaskWoken);
+
+    taskEXIT_CRITICAL_FROM_ISR();
+
+    /* 必要时进行任务切换 */
+    portYIELD_FROM_ISR(xHigherPriorityTaskWoken);
+}
+```
+
+**验证要点**:
+- 中断上下文安全性
+- 关键区域保护
+- 任务切换时机
+- 数据一致性保证
+
+### 2. 内存管理验证
+
+```c
+void* pvAllocateManagedMemory(size_t xSize) {
+    void* pvReturn = pvPortMalloc(xSize);
+
+    if (pvReturn != NULL) {
+        /* 追踪内存分配 */
+        vTrackAllocation(pvReturn, xSize);
+    }
+
+    return pvReturn;
+}
+```
+
+**验证要点**:

+
+**验证要点**:
+- 死锁预防
+- 优先级反转
+- 资源泄漏
+- 超时处理
+
+## 最佳实践
+
+### 1. 代码编写
+
+- **参数验证**: 始终验证函数参数
+- **错误处理**: 正确处理FreeRTOS API返回值
+- **资源管理**: 确保分配的资源被正确释放
+- **并发安全**: 使用适当的同步机制
+
+### 2. 验证策略
+
+- **增量验证**: 先验证基本功能，再验证复杂场景
+- **边界测试**: 重点测试边界条件和错误情况
+- **性能分析**: 监控内存使用和执行时间
+- **覆盖率最大化**: 使用突变测试提高验证覆盖率
+
+### 3. 配置优化
+
+```yaml
+# 生产环境验证配置
+verification:
+  depth: 25          # 增加搜索深度
+  unwind: 15         # 增加循环展开
+  timeout: 600       # 增加超时时间
+  max_memory: "2GB"  # 增加内存限制
+
+freertos:
+  max_tasks: 20      # 支持更多任务
+  stack_size: 2048   # 更大的栈空间
+  heap_size: 8192    # 更大的堆空间
+```
+
+## 故障排除
+
+### 常见问题
+
+1. **CBMC超时**
+   ```
+   解决方案:
+   - 减少验证深度 (--depth 15)
+   - 增加超时时间 (--timeout 600)
+   - 限制循环展开 (--unwind 5)
+   ```
+
+2. **内存不足**
+   ```
+   解决方案:
+   - 增加可用内存
+   - 简化验证条件
+   - 分批验证功能
+   ```
+
+3. **验证失败**
+   ```
+   解决方案:
+   - 检查反例路径
+   - 验证前置条件
+   - 增强错误处理
+   - 修改算法逻辑
+   ```
+
+### 调试技巧
+
+1. **逐步验证**: 先验证简单函数，再验证复杂逻辑
+2. **日志分析**: 启用详细日志输出分析问题
+3. **反例分析**: 仔细分析CBMC生成的反例
+4. **参数调优**: 根据代码复杂度调整验证参数
+
+## 扩展示例
+
+### 1. 复杂任务间通信
+
+创建 `complex_communication_example.c` 演示：
+- 多个生产者和消费者
+- 优先级调度
+- 事件通知机制
+- 复杂数据结构传递
+
+### 2. 定时器和定时服务
+
+创建 `timer_verification_example.c` 演示：
+- 软件定时器验证
+- 硬件定时器集成
+- 定时器回调安全性
+- 时间精度保证
+
+### 3. 外设驱动验证
+
+创建 `driver_verification_example.c` 演示：
+- 硬件抽象层验证
+- DMA操作安全性
+- 中断驱动处理
+- 外设配置验证

+本目录包含用于CodeDetect的FreeRTOS验证示例。
+
+## 目录结构
+
+- `simple_task.c` - 简单的FreeRTOS任务示例
+- `queue_example.c` - 队列操作示例
+- `mutex_example.c` - 互斥锁使用示例
+- `verify_with_cbmc.sh` - CBMC验证脚本
+
+## 环境设置
+
+确保已安装以下组件：
+
+1. **FreeRTOS**: 运行 `../scripts/setup-freertos-example.sh`
+2. **CBMC**: 安装CBMC模型检查器
+3. **CodeDetect**: 确保CodeDetect项目可用
+
+## 使用方法
+
+### 直接CBMC验证
+
+```bash
+# 验证单个文件
+cbmc --unwind 50 --depth 30 -I/opt/freertos/FreeRTOS/Source/include -DFREERTOS -DCBMC simple_task.c
+
+# 运行所有验证
+./verify_with_cbmc.sh
+```
+
+### 使用CodeDetect验证
+
+```bash
+# 从CodeDetect项目根目录运行
+python -m pytest tests/integration/test_freertos_verification.py -v
+
+# 或者使用完整的工作流
+python scripts/run_comprehensive_tests.sh --include freertos
+```
+
+## 示例说明
+
+### 1. 简单任务示例
+演示基本的任务创建和调度功能。
+
+### 2. 队列示例
+演示任务间通过队列进行通信。
+
+### 3. 互斥锁示例
+演示资源同步和互斥访问。
+
+## 验证目标
+
+- 内存安全性检查
+- 空指针解引用检测
+- 缓冲区溢出检查
+- 数据竞争检测
+- 死锁检测
+- 任务调度正确性
+
+## 故障排除
+
+### 常见问题
+
+1. **CBMC未找到**: 确保CBMC已安装并在PATH中
+2. **FreeRTOS头文件缺失**: 检查环境变量FREERTOS_PATH设置
+3. **验证超时**: 增加unwind和depth参数值
+
+### 调试技巧
+
+1. 使用`--show-properties`查看验证属性
+2. 使用`--trace`生成详细执行轨迹
+3. 使用`--xml-ui`获取结构化输出
+
+## 扩展示例
+
+要创建新的验证示例：
+
+1. 创建包含FreeRTOS API调用的C文件
+2. 确保包含必要的头文件
+3. 定义CBMC特定的宏
+4. 编写测试用例和断言
+

+**CBMC Syntax Reference:**
+
+**Basic Clauses:**
+- `\\requires(condition)` - Preconditions that must be true before function execution
+- `\\ensures(condition)` - Postconditions that must be true after function execution
+- `\\assigns(location)` - Specifies which memory locations may be modified
+
+**Quantifiers:**
+- `\\forall(type var : range; condition)` - Universal quantification
+- `\\exists(type var : range; condition)` - Existential quantification
+
+**Memory Safety:**
+- `\\valid(ptr)` - Pointer points to valid memory
+- `\\valid_read(ptr)` - Pointer points to readable memory
+- `\\valid_write(ptr)` - Pointer points to writable memory
+- `\\valid(ptr + size)` - Pointer with size specification
+
+**Array Bounds:**
+- `\\valid(array + i)` for array access at index i
+- `0 <= i < length` for bounds checking
+
+**Behaviors:**
+```
+\\behavior normal:
+  \\requires preconditions;
+  \\ensures postconditions;
+
+\\behavior error:
+  \\requires error_conditions;
+  \\ensures error_handling;
+
+\\complete behaviors;
+\\disjoint behaviors;
+```
+
+**Types and Expressions:**
+- Use C types: int, char*, void*, etc.
+- Use standard operators: &&, ||, !, ==, !=, <, >, <=, >=
+- Use pointer arithmetic: ptr + offset, ptr[size]
+- Use array notation: arr[i]
+
+**Best Practices:**
+1. Be specific about pointer validity and size
+2. Use quantifiers for array operations
+3. Handle all possible error conditions
+4. Ensure preconditions are not too restrictive
+5. Make postconditions as complete as possible
+6. Use behaviors for different execution paths
+7. Document assumptions and constraints

+\ensures \result >= a && \result >= b;
+\ensures \result == a || \result == b;
+\assigns \nothing;
+
+// 复杂函数规约
+\requires \valid(dest) && \valid(src) && dest_size > 0;
+\requires \separated(dest + (0..dest_size-1), src + (0..strlen(src)));
+\ensures (\forall size_t j; 0 <= j < \result ==> dest[j] == src[j]);
+\ensures dest[\result] == '\0';
+\assigns dest[0..dest_size-1];
+```
+
+## 🔧 技术架构
+
+### 核心组件
+- **API集成**: SiliconFlow DeepSeek v3.1
+- **规约生成**: 智能提示词工程
+- **后处理**: CBMC格式提取和规范化
+- **质量评估**: 自动质量评分系统
+
+### 工作流程
+1. 解析源代码，提取函数信息
+2. 构建验证目标和提示词
+3. 调用DeepSeek v3.1 API
+4. 生成CBMC格式规约
+5. 验证和评估规约质量
+6. 存储和返回结果
+
+## 🛠️ 开发指南
+
+### 添加新的测试用例
+1. 在相应的脚本中添加函数定义
+2. 配置验证目标
+3. 运行测试并验证结果
+
+### 自定义提示词
+修改系统提示词以适应特定需求：
+```python
+messages = [
+    {
+        "role": "system",
+        "content": "你的自定义系统提示词..."
+    }
+]
+```
+
+### 参数调优
+- `temperature`: 控制生成随机性 (0.1-0.7)
+- `max_tokens`: 控制输出长度 (512-2048)
+- `timeout`: 请求超时时间 (30-120秒)
+
+## 📈 性能优化
+
+### 批量处理
+使用批量生成提高效率：
+```python
+batch_requests = [request1, request2, request3]
+batch_results = await generate_batch_specifications(batch_requests)
+```
+
+### 缓存机制
+结果会自动缓存，避免重复生成。
+
+### 参数优化
+根据函数复杂度调整参数：
+- **简单函数**: temperature=0.3, max_tokens=512
+- **复杂函数**: temperature=0.1, max_tokens=2048
+
+## 🔍 故障排除
+
+### 常见问题
+1. **API密钥未设置**: 设置 `SILICONFLOW_API_KEY` 环境变量
+2. **网络连接问题**: 检查网络连接和API状态
+3. **生成质量低**: 调整temperature参数或提供更详细的验证目标
+
+### 调试模式
+启用详细日志：
+```python
+import logging
+logging.basicConfig(level=logging.DEBUG)
+```
+

+
+## 测试用例
+
+### 基础算术函数
+```c
+int add_numbers(int a, int b) {
+    return a + b;
+}
+```
+
+### 安全加法函数（带溢出检查）

+bool safe_add(int a, int b, int *result) {
+    if (result == NULL) {
+        return false;
+    }
+
+    if (a > 0 && b > INT_MAX - a) {
+        return false; // 正数溢出
+    }
+    if (a < 0 && b < INT_MIN - a) {
+        return false; // 负数溢出
+    }
+
+    *result = a + b;
+    return true;
+}
+```
+
+### 数组操作函数
+```c
+void array_copy(int *dest, const int *src, size_t size) {

+    }
+
+    for (size_t i = 0; i < size; i++) {
+        dest[i] = src[i];
+    }
+}
+```
+
+## 生成的 CBMC 规约示例
+
+### 简单函数规约
+```
+\\requires \\valid(a) && \\valid(b);
+\\ensures \\result == a + b;
+\\assigns \\nothing;
+```
+
+### 复杂函数规约

+\\requires \\valid(result) &&
+         ((a > 0 && b > 0) ==> a <= INT_MAX - b) &&
+         ((a < 0 && b < 0) ==> a >= INT_MIN - b);
+\\ensures \\result == true ==> *result == a + b;
+\\assigns *result;
+```
+

+
+## 高级功能
+
+### 1. 批量规约生成
+```python
+batch_requests = [request1, request2, request3]
+batch_results = await generator.generate_batch_specifications(batch_requests)
+```
+
+### 2. 流式生成
+```python
+async for chunk in generator.stream_specification(request):
+    print(chunk, end='', flush=True)
+```
+
+### 3. 规约优化
+```python
+refined_result = await generator.refine_specification(
+    original_spec=spec,
+    function_info=function_info,
+    issues=issues,
+    suggestions=suggestions
+)
+```
+
+### 4. 统计信息
+```python
+stats = generator.get_generation_stats()
+print(f"总规约数: {stats['total_specifications']}")
+print(f"平均质量: {stats['average_quality']:.2f}")
+```

+```
+
+## 技术架构
+
+### 核心组件
+1. **LLMGenerator**: 主要的规约生成器类
+2. **GenerationRequest**: 生成请求封装
+3. **GenerationResult**: 生成结果封装
+4. **PromptBuilder**: 提示词构建器
+5. **SpecValidator**: 规约验证器
+
+### 工作流程
+1. 解析源代码，提取函数信息
+2. 构建验证目标和提示词
+3. 调用 DeepSeek v3.1 API
+4. 生成 CBMC 格式规约
+5. 验证和评估规约质量
+6. 存储和返回结果
+
+## 扩展开发
+
+### 添加新的验证目标
+在 `GenerationRequest` 的 `verification_goals` 中添加新的目标类型：
+
+```python
+verification_goals=[
+    'functional_correctness',
+    'memory_safety',
+    'custom_verification_goal'  # 新目标
+]
+```
+
+### 自定义提示词
+修改 `src/spec/prompt_builder.py` 中的提示词模板，或使用 `context` 参数传递自定义提示词。
+
+### 集成其他模型
+修改 `LLMGenerator` 类的初始化参数，支持其他 LLM 模型：
+
+```python
+generator = LLMGenerator(
+    model='your-custom-model',
+    base_url='your-api-endpoint'
+)
+```
+
+## 性能优化
+
+### 1. 并发处理
+使用批量生成功能提高处理效率：
+
+```python
+# 并发处理多个函数
+batch_requests = [create_request(func) for func in functions]
+results = await generator.generate_batch_specifications(batch_requests)
+```
+
+### 2. 缓存机制
+启用结果缓存避免重复生成：
+
+```python
+# 生成结果会自动缓存
+result = await generator.generate_specification(request)
+```
+
+### 3. 参数调优
+根据使用场景调整生成参数：
+
+```python
+# 高精度模式（适合复杂函数）
+generator.temperature = 0.3
+generator.max_tokens = 8192
+
+# 快速模式（适合简单函数）
+generator.temperature = 0.7
+generator.max_tokens = 2048
+```
+
+## 故障排除
+
+### 日志调试
+启用详细日志：
+
+```python
+import logging
+logging.basicConfig(level=logging.DEBUG)
+```
+
+### API 问题
+检查 API 状态和配额：
+
+```python
+health = await generator.health_check()
+print(f"API 状态: {health['status']}")
+print(f"响应时间: {health['api_response_time']:.2f}s")
+```
+
+### 质量问题
+分析低质量规约的原因：
+
+```python
+if result.validation_result:
+    print(f"验证错误: {result.validation_result.errors}")
+    print(f"改进建议: {result.validation_result.suggestions}")
+```

+# 项目需求说明书：基于大型语言模型的形式化程序规范自动生成验证系统
+
+> 本文档基于提供的项目构思与附图，面向代码实现（供 Claude Code 阅读与落地）。
+
+## 1. 项目概述
+- 项目名称：基于大型语言模型的形式化程序规范自动生成验证系统
+- 开发单位：国防科大计算机学院22级软件工程小班刘卓小组
+- 用户单位：指挥中心、参战人员
+- 项目目标：利用大型语言模型（LLM）自动生成程序形式化规范，并结合 CBMC 对 C/C++ 程序进行验证，提升规范编写与验证效率与质量
+- 应用范围：以 C/C++ 程序为主，包含 FreeRTOS 内核相关验证示例与流程
+
+## 2. 背景与动机
+- 问题痛点：手工编写形式化规范耗时、难度高，模板/规则方法难准确覆盖复杂行为
+- 方案思路：用 LLM 对话式生成规范，再通过变异与优化提升规范质量，最终用 CBMC 验证并闭环改进
+- 预期价值：降低专业门槛、缩短验证周期、提升规范覆盖与一致性
+
+## 3. 功能需求
+### 3.1 代码输入与解析
+- 支持导入 C/C++ 源码（文件/目录/片段）
+- 完成基础语法解析，提取函数签名、调用关系、全局变量、注释等关键信息
+- 提供最小可验证单元选择（目标函数/模块）与属性选择（如内存安全）
+
+### 3.2 LLM 对话式规范生成
+- 基于 SiliconFlow DeepSeek V3.1 模型，自动生成初步形式化规范（CBMC 注释格式）
+- 支持对话式迭代补充假设、边界条件、接口契约、前后置条件与循环不变式
+- 集成 SiliconFlow API，支持流式响应和错误重试机制
+- 支持 CBMC 特有的语法元素：`\valid`、`\forall`、`\exists`、数组范围表达式等
+- 可保存与版本化规范草案
+
+### 3.3 规范变异与优化
+- 通过 CBMC 专用变异算子生成候选规范：
+  - **谓词变异**：`\forall` ↔ `\exists` 量词互换
+  - **边界变异**：`<` ↔ `<=`，`>` ↔ `>=` 比较符调整
+  - **逻辑变异**：`&&` ↔ `||`，`==>` ↔ `<==` 逻辑符转换
+  - **数组边界**：`0 .. n-1` ↔ `0 .. n` 范围调整
+  - **指针有效性**：`\valid(ptr)` ↔ `\valid_read(ptr)` 读写权限变更
+- 采用启发式选择策略，基于变异类型权重和验证历史选择最优候选
+
+### 3.4 验证执行与结果分析（CBMC）
+- 调用 CBMC 对目标程序/函数进行验证，支持多种检查类型：
+  - 内存安全（`--pointer-check`、`--bounds-check`）
+  - 数值安全（`--overflow-check`）
+  - 断言验证（`--assertions`）
+- 集成 FreeRTOS 验证流程：克隆代码库、配置环境、组织 `cbmc` 目录与脚本
+- 解析 CBMC 验证结果（VERIFICATION_SUCCESSFUL、FAILED、UNKNOWN）
+- 提取反例轨迹和错误位置，为规范修正提供精确反馈
+- 支持 CBMC 特有的结果分析：
+  - 展开深度不足的检测和建议
+  - 超时情况的优化建议
+  - 内存模型配置调整
+
+### 3.5 规范质量评估
+- **指标**：
+  - **准确性**：与程序行为一致，无假阳性/假阴性
+  - **完整性**：覆盖关键路径和边界条件
+  - **可验证性**：能被 CBMC 成功验证（无语法错误）
+  - **稳定性**：对变异操作鲁棒，验证结果一致
+  - **性能**：验证时间在可接受范围内
+  - **LLM 响应质量**：DeepSeek V3.1 生成的规范语法正确率和逻辑严谨性
+- **评估方法**：
+  - CBMC 验证通过率统计
+  - 变异体质量评分（基于启发式权重）
+  - 与手工编写的基准规范对比
+  - 验证时间复杂度分析
+  - LLM 响应时间和质量指标监控
+- **启发式选择策略**：
+  - **变异权重分配**：谓词变异(0.3)、边界变异(0.25)、逻辑变异(0.2)、数组边界(0.15)、指针有效性(0.1)
+  - **历史成功率**：基于过往验证结果调整权重
+  - **复杂度惩罚**：过于复杂的规范降低选择概率
+  - **验证时间考量**：优先选择验证时间较短的候选
+  - **LLM 置信度**：考虑 DeepSeek V3.1 输出的置信度评分
+
+### 3.6 界面与交互
+- **代码导入区域**：支持文件上传、代码粘贴
+- **解析结果展示**：函数结构、调用关系的可视化展示
+- **验证属性配置**：选择验证类型（内存安全、溢出检测等）
+- **规范生成控制**：生成、变异、验证执行的控制面板
+- **结果展示区域**：规范版本、验证日志、反例轨迹展示
+- **评估报告中心**：质量指标、通过率统计展示
+- **实时进度显示**：当前执行步骤和进度条
+- **响应式设计**：支持桌面浏览器显示
+
+## 4. 业务流程（高层）
+1) 导入 C/C++ 代码 → 解析结构信息，提取函数签名、全局变量、数据结构
+2) 采集意图与约束 → LLM 生成 CBMC 格式的初版规范（requires/ensures/invariants）
+3) 应用 CBMC 专用变异算子 → 生成候选规范集合
+4) 启发式选择策略 → 筛选最有希望的候选规范
+5) 调 CBMC 验证 → 解析验证结果、反例轨迹和错误信息
+6) 依据 CBMC 反馈自动/交互修正规范 → 迭代至收敛
+7) 输出最终规范与验证报告
+
+## 5. 系统组成与部署
+- 源码库克隆：克隆 FreeRTOS 内核及其子模块，作为验证示例与基准
+- 环境配置：创建 `cbmc` 目录用于验证相关文件与脚本；完成初始配置脚本执行
+- 工具与脚本：采用 `Makefile.common`、`run-cbmc-proofs.py` 等脚本组织与批量执行验证

+## 11. 接口与文件格式（建议）
+### 11.1 规范存储（CBMC 格式）
+```json
+{
+  "target": {
+    "file": "path/to/foo.c",
+    "function": "foo",
+    "properties": ["memory_safety", "overflow_detection"]
+  },
+  "cbmc_spec": {
+    "requires": [
+      "ptr != NULL",
+      "len >= 0",
+      "\\valid(ptr + (0 .. len-1))"
+    ],
+    "ensures": [
+      "return >= 0",
+      "no_overflow",
+      "\\forall int i; 0 <= i < len ==> result[i] == input[i]"
+    ],
+    "loop_invariants": [
+      "i >= 0 && i <= len",
+      "\\forall int j; 0 <= j < i ==> temp[j] == source[j]"
+    ],
+    "assumptions": [
+      "external_api_returns_valid_data",
+      "SIZE_MAX == 4294967295"
+    ]
+  },
+  "cbmc_config": {
+    "unwinding": 10,
+    "pointer_check": true,
+    "overflow_check": true,
+    "bounds_check": true
+  }
+}
+```
+
+### 11.2 验证调用（示意）
+**输入**：规范 JSON、目标源码路径、CBMC 配置
+
+**过程**：
+1. 根据规范 JSON 生成或更新测试 harness 代码
+2. 配置 CBMC 验证参数（内存模型、展开深度、超时时间）
+3. 调用 `run-cbmc-proofs.py` 或 `make -f Makefile.common <proof>` 执行验证
+4. 监控验证进度，处理超时与异常
+
+**输出**：结果 JSON（SUCCESSFUL/FAILED/UNKNOWN/超时）、详细日志、反例轨迹（若有）
+
+**CBMC 结果解析示例**：
+```json
+{
+  "status": "FAILED",
+  "verification_time": 45.2,
+  "unwinding_depth": 10,
+  "counterexample": {
+    "error_type": "array_bounds_violation",
+    "location": "buffer_utils.c:42",
+    "trace": [
+      {"variable": "n", "value": "100"},
+      {"variable": "buffer_size", "value": "50"},
+      {"error": "Buffer overflow detected"}
+    ]
+  },
+  "cbmc_output": "Violated property:\n  file buffer_utils.c line 42 function safe_copy\n  Array buffer bounds: buffer[50] access on line 42 may be out of bounds",
+  "suggestions": [
+    "Add requires clause: n <= buffer_size",
+    "Add bounds check before array access"
+  ]
+}
+```
+
+示例调用流程：
+```python
+# 1. 准备验证输入
+verification_input = {
+    "spec_file": "specs/buffer_overflow_spec.json",
+    "target_code": "src/buffer_utils.c",
+    "function": "safe_copy",
+    "cbmc_config": {
+        "unwinding": 10,
+        "timeout": 300,
+        "memory_model": "precise"
+    }
+}
+
+# 2. 生成 harness
+harness_generator.generate(verification_input)
+
+# 3. 执行 CBMC 验证
+result = cbmc_runner.run_verification(
+    proof_name="buffer_overflow_proof",
+    config=verification_input["cbmc_config"]
+)
+
+# 4. 解析结果
+verification_result = {
+    "status": "FAILED" | "PASSED" | "TIMEOUT",
+    "counterexample": {...},  # 如有反例
+    "verification_time": 45.2,
+    "log_file": "logs/buffer_overflow_proof.log"
+}
+```
+
+### 11.3 LLM 提示要素（DeepSeek V3.1 + CBMC 专用）
+构建高质量的 LLM 提示是 CBMC 规范生成成功的关键，建议包含以下要素：
+
+**代码上下文**：
+- 函数签名与参数类型
+- 全局变量与宏定义
+- 相关数据结构定义
+- 函数内联注释与文档
+- 相关的 CBMC 配置选项
+
+**CBMC 特定语法指导**：
+- 使用 `/*@ ... @*/` 注释格式
+- 正确使用 `\valid`、`\valid_read` 指针检查
+- 数组范围表达式：`array + (0 .. size-1)`
+- 量词表达式：`\forall`、`\exists`
+- 循环不变式：`loop invariant`
+
+**验证属性**：
+- 内存安全（`\valid(ptr)` 防止空指针和越界）
+- 数值安全（整数溢出检查）
+- 数组边界检查（`0 <= index && index < size`）
+- 指针解引用安全（`*ptr` 前检查指针有效性）
+
+**输出格式要求**：
+- CBMC 兼容的注释语法
+- 结构化的前置/后置条件
+- 可验证的循环不变式
+
+**DeepSeek V3.1 优化建议**：
+- 利用其强大的代码理解能力，提供更精确的 C 语言分析
+- 利用其逻辑推理能力，生成更严谨的形式化规范
+- 控制响应长度，避免过于冗长的规范描述
+
+示例提示模板：
+```
+请为以下 C 函数生成 CBMC 形式化规范：
+
+[函数代码]
+void safe_memcpy(void* dst, const void* src, size_t n) {
+    // ... 实现代码
+}
+
+[CBMC 语法指导]
+使用 /*@ requires ... @*/ 格式，支持以下语法：
+- 指针有效性：\\valid(ptr + (0 .. n-1))
+- 数组访问：ptr[i] 前检查 0 <= i < n
+- 全称量词：\\forall type i; range ==> condition
+- 存在量词：\\exists type i; range && condition
+
+[验证目标]
+- 内存安全：防止缓冲区溢出和空指针解引用
+- 正确性：正确复制指定字节数，无数据丢失
+- 边界检查：n 在有效范围内（0 <= n <= SIZE_MAX）
+
+[输出要求]
+请以 CBMC 注释格式输出规范，包含 requires、ensures、loop_invariants。
+```

+## 🚀 快速开始
+
+### 方法一：使用启动脚本（推荐）
+
+```bash
+# 进入Web接口目录
+cd web_interface
+
+# 运行启动脚本
+./start_web_interface.sh
+```
+
+### 方法二：手动启动
+
+```bash
+# 进入后端目录
+cd web_interface/backend
+
+# 创建虚拟环境
+python3 -m venv venv
+source venv/bin/activate
+
+# 安装依赖
+pip install -r requirements.txt
+
+# 启动服务器
+python app.py
+```
+
+## 🌐 访问界面
+
+启动后，在浏览器中访问：
+- **本地访问**: http://localhost:8080
+- **网络访问**: http://[你的IP地址]:8080
+
+## 📋 系统要求
+
+- Python 3.8+
+- CBMC (用于实际验证)
+- 现代Web浏览器
+
+## 🎯 使用方法
+
+1. **打开浏览器**，访问Web界面
+2. **加载示例代码**或**输入自定义C代码**
+3. **点击"开始验证"**按钮
+4. **查看实时进度**和**验证结果**
+5. **分析生成的断言代码**和**CBMC验证输出**
+
+## 🔧 API接口
+
+### 创建验证任务
+```bash
+POST /api/tasks
+Content-Type: application/json
+
+{
+    "input_code": "#include <stdio.h>\nint main() { return 0; }",
+    "options": {}
+}
+```
+
+### 查询任务状态
+```bash
+GET /api/tasks/{task_id}
+```
+
+### 获取任务结果
+```bash
+GET /api/tasks/{task_id}/result
+```
+
+### 获取系统信息
+```bash
+GET /api/system/info
+```
+
+### 获取示例代码
+```bash
+GET /api/demo/sample
+```

+   ```bash
+   # 查看占用端口的进程
+   lsof -i :8080
+   # 终止进程
+   kill -9 <PID>
+   ```
+
+2. **虚拟环境问题**
+   ```bash
+   # 删除并重新创建虚拟环境
+   rm -rf venv
+   python3 -m venv venv
+   source venv/bin/activate
+   pip install -r requirements.txt
+   ```
+
+3. **依赖安装失败**
+   ```bash
+   # 更新pip
+   pip install --upgrade pip
+   # 使用国内镜像
+   pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple/
+   ```
+

+<#
+.Synopsis
+Activate a Python virtual environment for the current PowerShell session.
+
+.Description
+Pushes the python executable for a virtual environment to the front of the
+$Env:PATH environment variable and sets the prompt to signify that you are
+in a Python virtual environment. Makes use of the command line switches as
+well as the `pyvenv.cfg` file values present in the virtual environment.
+
+.Parameter VenvDir
+Path to the directory that contains the virtual environment to activate. The
+default value for this is the parent of the directory that the Activate.ps1
+script is located within.
+
+.Parameter Prompt
+The prompt prefix to display when this virtual environment is activated. By
+default, this prompt is the name of the virtual environment folder (VenvDir)
+surrounded by parentheses and followed by a single space (ie. '(.venv) ').
+
+.Example
+Activate.ps1
+Activates the Python virtual environment that contains the Activate.ps1 script.
+
+.Example
+Activate.ps1 -Verbose
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and shows extra information about the activation as it executes.
+
+.Example
+Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
+Activates the Python virtual environment located in the specified location.
+
+.Example
+Activate.ps1 -Prompt "MyPython"
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and prefixes the current prompt with the specified string (surrounded in
+parentheses) while the virtual environment is active.
+
+.Notes
+On Windows, it may be required to enable this Activate.ps1 script by setting the
+execution policy for the user. You can do this by issuing the following PowerShell
+command:
+
+PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+
+For more information on Execution Policies: 
+https://go.microsoft.com/fwlink/?LinkID=135170

+Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the

+two strings separated by `=` (with any amount of whitespace surrounding the =)
+then it is considered a `key = value` line. The left hand string is the key,
+the right hand is the value.
+
+If the value starts with a `'` or a `"` then the first and last character is
+stripped from the value before being captured.

+Flask-CORS
+==========
+
+|Build Status| |Latest Version| |Supported Python versions|
+|License|
+
+A Flask extension for handling Cross Origin Resource Sharing (CORS), making cross-origin AJAX possible.
+
+This package has a simple philosophy: when you want to enable CORS, you wish to enable it for all use cases on a domain. 
+This means no mucking around with different allowed headers, methods, etc. 
+
+By default, submission of cookies across domains is disabled due to the security implications. 
+Please see the documentation for how to enable credential'ed requests, and please make sure you add some sort of `CSRF <http://en.wikipedia.org/wiki/Cross-site_request_forgery>`__ protection before doing so!
+
+Installation
+------------
+
+Install the extension with using pip, or easy\_install.
+
+.. code:: bash
+
+    $ pip install -U flask-cors
+
+Usage
+-----
+
+This package exposes a Flask extension which by default enables CORS support on all routes, for all origins and methods. 
+It allows parameterization of all CORS headers on a per-resource level. 
+The package also contains a decorator, for those who prefer this approach.
+
+Simple Usage
+~~~~~~~~~~~~
+
+In the simplest case, initialize the Flask-Cors extension with default arguments in order to allow CORS for all domains on all routes. 
+See the full list of options in the `documentation <https://flask-cors.corydolphin.com/en/latest/api.html#extension>`__.
+
+.. code:: python
+
+
+    from flask import Flask
+    from flask_cors import CORS
+
+    app = Flask(__name__)
+    CORS(app)
+
+    @app.route("/")
+    def helloWorld():
+      return "Hello, cross-origin-world!"
+
+Resource specific CORS
+^^^^^^^^^^^^^^^^^^^^^^
+
+Alternatively, you can specify CORS options on a resource and origin level of granularity by passing a dictionary as the `resources` option, mapping paths to a set of options. 
+See the full list of options in the `documentation <https://flask-cors.corydolphin.com/en/latest/api.html#extension>`__.
+
+.. code:: python
+
+    app = Flask(__name__)
+    cors = CORS(app, resources={r"/api/*": {"origins": "*"}})
+
+    @app.route("/api/v1/users")
+    def list_users():
+      return "user example"
+
+Route specific CORS via decorator
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This extension also exposes a simple decorator to decorate flask routes with. 
+Simply add ``@cross_origin()`` below a call to Flask's ``@app.route(..)`` to allow CORS on a given route. 
+See the full list of options in the `decorator documentation <https://flask-cors.corydolphin.com/en/latest/api.html#decorator>`__.
+
+.. code:: python
+
+    @app.route("/")
+    @cross_origin()
+    def helloWorld():
+      return "Hello, cross-origin-world!"
+
+Documentation
+-------------
+
+For a full list of options, please see the full `documentation <https://flask-cors.corydolphin.com/en/latest/api.html>`__
+
+Troubleshooting
+---------------
+
+If things aren't working as you expect, enable logging to help understand what is going on under the hood, and why.
+
+.. code:: python
+
+    logging.getLogger('flask_cors').level = logging.DEBUG
+
+
+Tests
+-----
+
+A simple set of tests is included in ``test/``. 
+To run, install nose, and simply invoke ``nosetests`` or ``python setup.py test`` to exercise the tests.
+
+If nosetests does not work for you, due to it no longer working with newer python versions.
+You can use pytest to run the tests instead.
+
+Contributing
+------------
+
+Questions, comments or improvements? 
+Please create an issue on `Github <https://github.com/corydolphin/flask-cors>`__, tweet at `@corydolphin <https://twitter.com/corydolphin>`__ or send me an email. 
+I do my best to include every contribution proposed in any way that I can.

+
+[PEP-593](https://peps.python.org/pep-0593/) added `typing.Annotated` as a way of
+adding context-specific metadata to existing types, and specifies that
+`Annotated[T, x]` _should_ be treated as `T` by any tool or library without special
+logic for `x`.
+
+This package provides metadata objects which can be used to represent common
+constraints such as upper and lower bounds on scalar values and collection sizes,
+a `Predicate` marker for runtime checks, and
+descriptions of how we intend these metadata to be interpreted. In some cases,
+we also note alternative representations which do not require this package.
+
+## Install
+
+```bash
+pip install annotated-types
+```
+
+## Examples
+
+```python
+from typing import Annotated
+from annotated_types import Gt, Len, Predicate
+
+class MyClass:
+    age: Annotated[int, Gt(18)]                         # Valid: 19, 20, ...
+                                                        # Invalid: 17, 18, "19", 19.0, ...
+    factors: list[Annotated[int, Predicate(is_prime)]]  # Valid: 2, 3, 5, 7, 11, ...
+                                                        # Invalid: 4, 8, -2, 5.0, "prime", ...
+
+    my_list: Annotated[list[int], Len(0, 10)]           # Valid: [], [10, 20, 30, 40, 50]
+                                                        # Invalid: (1, 2), ["abc"], [0] * 20
+```
+
+## Documentation
+
+_While `annotated-types` avoids runtime checks for performance, users should not
+construct invalid combinations such as `MultipleOf("non-numeric")` or `Annotated[int, Len(3)]`.
+Downstream implementors may choose to raise an error, emit a warning, silently ignore
+a metadata item, etc., if the metadata objects described below are used with an
+incompatible type - or for any other reason!_
+
+### Gt, Ge, Lt, Le
+
+Express inclusive and/or exclusive bounds on orderable values - which may be numbers,
+dates, times, strings, sets, etc. Note that the boundary value need not be of the
+same type that was annotated, so long as they can be compared: `Annotated[int, Gt(1.5)]`
+is fine, for example, and implies that the value is an integer x such that `x > 1.5`.
+
+We suggest that implementors may also interpret `functools.partial(operator.le, 1.5)`
+as being equivalent to `Gt(1.5)`, for users who wish to avoid a runtime dependency on
+the `annotated-types` package.
+
+To be explicit, these types have the following meanings:
+
+* `Gt(x)` - value must be "Greater Than" `x` - equivalent to exclusive minimum
+* `Ge(x)` - value must be "Greater than or Equal" to `x` - equivalent to inclusive minimum
+* `Lt(x)` - value must be "Less Than" `x` - equivalent to exclusive maximum
+* `Le(x)` - value must be "Less than or Equal" to `x` - equivalent to inclusive maximum
+
+### Interval
+
+`Interval(gt, ge, lt, le)` allows you to specify an upper and lower bound with a single
+metadata object. `None` attributes should be ignored, and non-`None` attributes
+treated as per the single bounds above.
+
+### MultipleOf
+
+`MultipleOf(multiple_of=x)` might be interpreted in two ways:
+
+1. Python semantics, implying `value % multiple_of == 0`, or
+2. [JSONschema semantics](https://json-schema.org/draft/2020-12/json-schema-validation.html#rfc.section.6.2.1),
+   where `int(value / multiple_of) == value / multiple_of`.
+
+We encourage users to be aware of these two common interpretations and their
+distinct behaviours, especially since very large or non-integer numbers make
+it easy to cause silent data corruption due to floating-point imprecision.
+
+We encourage libraries to carefully document which interpretation they implement.
+
+### MinLen, MaxLen, Len
+
+`Len()` implies that `min_length <= len(value) <= max_length` - lower and upper bounds are inclusive.
+
+As well as `Len()` which can optionally include upper and lower bounds, we also
+provide `MinLen(x)` and `MaxLen(y)` which are equivalent to `Len(min_length=x)`
+and `Len(max_length=y)` respectively.
+
+`Len`, `MinLen`, and `MaxLen` may be used with any type which supports `len(value)`.
+
+Examples of usage:
+
+* `Annotated[list, MaxLen(10)]` (or `Annotated[list, Len(max_length=10))`) - list must have a length of 10 or less
+* `Annotated[str, MaxLen(10)]` - string must have a length of 10 or less
+* `Annotated[list, MinLen(3))` (or `Annotated[list, Len(min_length=3))`) - list must have a length of 3 or more
+* `Annotated[list, Len(4, 6)]` - list must have a length of 4, 5, or 6
+* `Annotated[list, Len(8, 8)]` - list must have a length of exactly 8
+
+#### Changed in v0.4.0
+
+* `min_inclusive` has been renamed to `min_length`, no change in meaning
+* `max_exclusive` has been renamed to `max_length`, upper bound is now **inclusive** instead of **exclusive**
+* The recommendation that slices are interpreted as `Len` has been removed due to ambiguity and different semantic
+  meaning of the upper bound in slices vs. `Len`
+
+See [issue #23](https://github.com/annotated-types/annotated-types/issues/23) for discussion.
+
+### Timezone
+
+`Timezone` can be used with a `datetime` or a `time` to express which timezones
+are allowed. `Annotated[datetime, Timezone(None)]` must be a naive datetime.
+`Timezone[...]` ([literal ellipsis](https://docs.python.org/3/library/constants.html#Ellipsis))
+expresses that any timezone-aware datetime is allowed. You may also pass a specific
+timezone string or [`tzinfo`](https://docs.python.org/3/library/datetime.html#tzinfo-objects)
+object such as `Timezone(timezone.utc)` or `Timezone("Africa/Abidjan")` to express that you only
+allow a specific timezone, though we note that this is often a symptom of fragile design.
+
+#### Changed in v0.x.x
+
+* `Timezone` accepts [`tzinfo`](https://docs.python.org/3/library/datetime.html#tzinfo-objects) objects instead of
+  `timezone`, extending compatibility to [`zoneinfo`](https://docs.python.org/3/library/zoneinfo.html) and third party libraries.
+
+### Unit
+
+`Unit(unit: str)` expresses that the annotated numeric value is the magnitude of
+a quantity with the specified unit. For example, `Annotated[float, Unit("m/s")]`
+would be a float representing a velocity in meters per second.
+
+Please note that `annotated_types` itself makes no attempt to parse or validate
+the unit string in any way. That is left entirely to downstream libraries,
+such as [`pint`](https://pint.readthedocs.io) or
+[`astropy.units`](https://docs.astropy.org/en/stable/units/).
+
+An example of how a library might use this metadata:
+
+```python
+from annotated_types import Unit
+from typing import Annotated, TypeVar, Callable, Any, get_origin, get_args
+
+# given a type annotated with a unit:
+Meters = Annotated[float, Unit("m")]
+
+
+# you can cast the annotation to a specific unit type with any
+# callable that accepts a string and returns the desired type
+T = TypeVar("T")
+def cast_unit(tp: Any, unit_cls: Callable[[str], T]) -> T | None:
+    if get_origin(tp) is Annotated:
+        for arg in get_args(tp):
+            if isinstance(arg, Unit):
+                return unit_cls(arg.unit)
+    return None
+
+
+# using `pint`
+import pint
+pint_unit = cast_unit(Meters, pint.Unit)
+
+
+# using `astropy.units`
+import astropy.units as u
+astropy_unit = cast_unit(Meters, u.Unit)
+```
+
+### Predicate
+
+`Predicate(func: Callable)` expresses that `func(value)` is truthy for valid values.
+Users should prefer the statically inspectable metadata above, but if you need
+the full power and flexibility of arbitrary runtime predicates... here it is.
+
+For some common constraints, we provide generic types:
+
+* `IsLower       = Annotated[T, Predicate(str.islower)]`
+* `IsUpper       = Annotated[T, Predicate(str.isupper)]`
+* `IsDigit       = Annotated[T, Predicate(str.isdigit)]`
+* `IsFinite      = Annotated[T, Predicate(math.isfinite)]`
+* `IsNotFinite   = Annotated[T, Predicate(Not(math.isfinite))]`
+* `IsNan         = Annotated[T, Predicate(math.isnan)]`
+* `IsNotNan      = Annotated[T, Predicate(Not(math.isnan))]`
+* `IsInfinite    = Annotated[T, Predicate(math.isinf)]`
+* `IsNotInfinite = Annotated[T, Predicate(Not(math.isinf))]`
+
+so that you can write e.g. `x: IsFinite[float] = 2.0` instead of the longer
+(but exactly equivalent) `x: Annotated[float, Predicate(math.isfinite)] = 2.0`.
+
+Some libraries might have special logic to handle known or understandable predicates,
+for example by checking for `str.isdigit` and using its presence to both call custom
+logic to enforce digit-only strings, and customise some generated external schema.
+Users are therefore encouraged to avoid indirection like `lambda s: s.lower()`, in
+favor of introspectable methods such as `str.lower` or `re.compile("pattern").search`.
+
+To enable basic negation of commonly used predicates like `math.isnan` without introducing introspection that makes it impossible for implementers to introspect the predicate we provide a `Not` wrapper that simply negates the predicate in an introspectable manner. Several of the predicates listed above are created in this manner.
+
+We do not specify what behaviour should be expected for predicates that raise
+an exception.  For example `Annotated[int, Predicate(str.isdigit)]` might silently
+skip invalid constraints, or statically raise an error; or it might try calling it
+and then propagate or discard the resulting
+`TypeError: descriptor 'isdigit' for 'str' objects doesn't apply to a 'int' object`
+exception.  We encourage libraries to document the behaviour they choose.
+
+### Doc
+
+`doc()` can be used to add documentation information in `Annotated`, for function and method parameters, variables, class attributes, return types, and any place where `Annotated` can be used.
+
+It expects a value that can be statically analyzed, as the main use case is for static analysis, editors, documentation generators, and similar tools.
+
+It returns a `DocInfo` class with a single attribute `documentation` containing the value passed to `doc()`.
+
+This is the early adopter's alternative form of the [`typing-doc` proposal](https://github.com/tiangolo/fastapi/blob/typing-doc/typing_doc.md).
+
+### Integrating downstream types with `GroupedMetadata`
+
+Implementers may choose to provide a convenience wrapper that groups multiple pieces of metadata.
+This can help reduce verbosity and cognitive overhead for users.
+For example, an implementer like Pydantic might provide a `Field` or `Meta` type that accepts keyword arguments and transforms these into low-level metadata:
+
+```python
+from dataclasses import dataclass
+from typing import Iterator
+from annotated_types import GroupedMetadata, Ge
+
+@dataclass
+class Field(GroupedMetadata):
+    ge: int | None = None
+    description: str | None = None
+
+    def __iter__(self) -> Iterator[object]:
+        # Iterating over a GroupedMetadata object should yield annotated-types
+        # constraint metadata objects which describe it as fully as possible,
+        # and may include other unknown objects too.
+        if self.ge is not None:
+            yield Ge(self.ge)
+        if self.description is not None:
+            yield Description(self.description)
+```
+
+Libraries consuming annotated-types constraints should check for `GroupedMetadata` and unpack it by iterating over the object and treating the results as if they had been "unpacked" in the `Annotated` type.  The same logic should be applied to the [PEP 646 `Unpack` type](https://peps.python.org/pep-0646/), so that `Annotated[T, Field(...)]`, `Annotated[T, Unpack[Field(...)]]` and `Annotated[T, *Field(...)]` are all treated consistently.
+
+Libraries consuming annotated-types should also ignore any metadata they do not recongize that came from unpacking a `GroupedMetadata`, just like they ignore unrecognized metadata in `Annotated` itself.
+
+Our own `annotated_types.Interval` class is a `GroupedMetadata` which unpacks itself into `Gt`, `Lt`, etc., so this is not an abstract concern.  Similarly, `annotated_types.Len` is a `GroupedMetadata` which unpacks itself into `MinLen` (optionally) and `MaxLen`.
+
+### Consuming metadata
+
+We intend to not be prescriptive as to _how_ the metadata and constraints are used, but as an example of how one might parse constraints from types annotations see our [implementation in `test_main.py`](https://github.com/annotated-types/annotated-types/blob/f59cf6d1b5255a0fe359b93896759a180bec30ae/tests/test_main.py#L94-L103).
+
+It is up to the implementer to determine how this metadata is used.
+You could use the metadata for runtime type checking, for generating schemas or to generate example data, amongst other use cases.
+
+## Design & History
+
+This package was designed at the PyCon 2022 sprints by the maintainers of Pydantic
+and Hypothesis, with the goal of making it as easy as possible for end-users to
+provide more informative annotations for use by runtime libraries.
+
+It is deliberately minimal, and following PEP-593 allows considerable downstream
+discretion in what (if anything!) they choose to support. Nonetheless, we expect
+that staying simple and covering _only_ the most common use-cases will give users
+and maintainers the best experience we can. If you'd like more constraints for your
+types - follow our lead, by defining them and documenting them downstream!

+
+AnyIO is an asynchronous networking and concurrency library that works on top of either asyncio_ or
+trio_. It implements trio-like `structured concurrency`_ (SC) on top of asyncio and works in harmony
+with the native SC of trio itself.
+
+Applications and libraries written against AnyIO's API will run unmodified on either asyncio_ or
+trio_. AnyIO can also be adopted into a library or application incrementally – bit by bit, no full
+refactoring necessary. It will blend in with the native libraries of your chosen backend.
+
+Documentation
+-------------
+
+View full documentation at: https://anyio.readthedocs.io/
+
+Features
+--------
+
+AnyIO offers the following functionality:
+
+* Task groups (nurseries_ in trio terminology)
+* High-level networking (TCP, UDP and UNIX sockets)
+
+  * `Happy eyeballs`_ algorithm for TCP connections (more robust than that of asyncio on Python
+    3.8)
+  * async/await style UDP sockets (unlike asyncio where you still have to use Transports and
+    Protocols)
+
+* A versatile API for byte streams and object streams
+* Inter-task synchronization and communication (locks, conditions, events, semaphores, object
+  streams)
+* Worker threads
+* Subprocesses
+* Asynchronous file I/O (using worker threads)
+* Signal handling
+
+AnyIO also comes with its own pytest_ plugin which also supports asynchronous fixtures.
+It even works with the popular Hypothesis_ library.

+# Blinker
+
+Blinker provides a fast dispatching system that allows any number of
+interested parties to subscribe to events, or "signals".
+

+
+## Example
+
+Signal receivers can subscribe to specific senders or receive signals
+sent by any sender.
+
+```pycon
+>>> from blinker import signal
+>>> started = signal('round-started')
+>>> def each(round):
+...     print(f"Round {round}")
+...
+>>> started.connect(each)
+
+>>> def round_two(round):
+...     print("This is round two.")
+...
+>>> started.connect(round_two, sender=2)
+
+>>> for round in range(1, 4):
+...     started.send(round)
+...
+Round 1!
+Round 2!
+This is round two.
+Round 3!
+```

+Certifi: Python SSL Certificates
+================================
+
+Certifi provides Mozilla's carefully curated collection of Root Certificates for
+validating the trustworthiness of SSL certificates while verifying the identity
+of TLS hosts. It has been extracted from the `Requests`_ project.
+
+Installation
+------------
+
+``certifi`` is available on PyPI. Simply install it with ``pip``::
+
+    $ pip install certifi
+
+Usage
+-----
+
+To reference the installed certificate authority (CA) bundle, you can use the
+built-in function::
+
+    >>> import certifi
+
+    >>> certifi.where()
+    '/usr/local/lib/python3.7/site-packages/certifi/cacert.pem'
+
+Or from the command line::
+
+    $ python -m certifi
+    /usr/local/lib/python3.7/site-packages/certifi/cacert.pem
+
+Enjoy!
+
+.. _`Requests`: https://requests.readthedocs.io/en/master/
+
+Addition/Removal of Certificates
+--------------------------------
+
+Certifi does not support any addition/removal or other modification of the
+CA trust store content. This project is intended to provide a reliable and
+highly portable root of trust to python deployments. Look to upstream projects
+for methods to use alternate trust.

+This package contains a modified version of ca-bundle.crt:
+
+ca-bundle.crt -- Bundle of CA Root Certificates
+
+This is a bundle of X.509 certificates of public Certificate Authorities
+(CA). These were automatically extracted from Mozilla's root certificates
+file (certdata.txt).  This file can be found in the mozilla source tree:
+https://hg.mozilla.org/mozilla-central/file/tip/security/nss/lib/ckfw/builtins/certdata.txt
+It contains the certificates in PEM format and therefore
+can be directly used with curl / libcurl / php_curl, or with
+an Apache+mod_ssl webserver for SSL client authentication.
+Just configure this file as the SSLCACertificateFile.#

+
+_updated as of december 2024 using CPython 3.12_
+
+Chardet's performance on larger file (1MB+) are very poor. Expect huge difference on large payload.
+
+> Stats are generated using 400+ files using default parameters. More details on used files, see GHA workflows.
+> And yes, these results might change at any time. The dataset can be updated to include more files.
+> The actual delays heavily depends on your CPU capabilities. The factors should remain the same.
+> Keep in mind that the stats are generous and that Chardet accuracy vs our is measured using Chardet initial capability
+> (e.g. Supported Encoding) Challenge-them if you want.
+
+## ✨ Installation
+
+Using pip:
+
+```sh
+pip install charset-normalizer -U
+```
+
+## 🚀 Basic Usage
+
+### CLI
+This package comes with a CLI.
+
+```
+usage: normalizer [-h] [-v] [-a] [-n] [-m] [-r] [-f] [-t THRESHOLD]
+                  file [file ...]
+
+The Real First Universal Charset Detector. Discover originating encoding used
+on text file. Normalize text to unicode.
+
+positional arguments:
+  files                 File(s) to be analysed
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -v, --verbose         Display complementary information about file if any.
+                        Stdout will contain logs about the detection process.
+  -a, --with-alternative
+                        Output complementary possibilities if any. Top-level
+                        JSON WILL be a list.
+  -n, --normalize       Permit to normalize input file. If not set, program
+                        does not write anything.
+  -m, --minimal         Only output the charset detected to STDOUT. Disabling
+                        JSON output.
+  -r, --replace         Replace file when trying to normalize it instead of
+                        creating a new one.
+  -f, --force           Replace file without asking if you are sure, use this
+                        flag with caution.
+  -t THRESHOLD, --threshold THRESHOLD
+                        Define a custom maximum amount of chaos allowed in
+                        decoded content. 0. <= chaos <= 1.
+  --version             Show version information and exit.
+```
+
+```bash
+normalizer ./data/sample.1.fr.srt
+```
+
+or
+
+```bash
+python -m charset_normalizer ./data/sample.1.fr.srt
+```
+
+🎉 Since version 1.4.0 the CLI produce easily usable stdout result in JSON format.
+
+```json
+{
+    "path": "/home/default/projects/charset_normalizer/data/sample.1.fr.srt",
+    "encoding": "cp1252",
+    "encoding_aliases": [
+        "1252",
+        "windows_1252"
+    ],
+    "alternative_encodings": [
+        "cp1254",
+        "cp1256",
+        "cp1258",
+        "iso8859_14",
+        "iso8859_15",
+        "iso8859_16",
+        "iso8859_3",
+        "iso8859_9",
+        "latin_1",
+        "mbcs"
+    ],
+    "language": "French",
+    "alphabets": [
+        "Basic Latin",
+        "Latin-1 Supplement"
+    ],
+    "has_sig_or_bom": false,
+    "chaos": 0.149,
+    "coherence": 97.152,
+    "unicode_path": null,
+    "is_preferred": true
+}
+```
+
+### Python
+*Just print out normalized text*
+```python
+from charset_normalizer import from_path
+
+results = from_path('./my_subtitle.srt')
+
+print(str(results.best()))
+```
+
+*Upgrade your code without effort*
+```python
+from charset_normalizer import detect
+```
+
+The above code will behave the same as **chardet**. We ensure that we offer the best (reasonable) BC result possible.
+
+See the docs for advanced usage : [readthedocs.io](https://charset-normalizer.readthedocs.io/en/latest/)
+
+## 😇 Why
+
+When I started using Chardet, I noticed that it was not suited to my expectations, and I wanted to propose a
+reliable alternative using a completely different method. Also! I never back down on a good challenge!
+
+I **don't care** about the **originating charset** encoding, because **two different tables** can
+produce **two identical rendered string.**
+What I want is to get readable text, the best I can.
+
+In a way, **I'm brute forcing text decoding.** How cool is that ? 😎
+
+Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair Unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode.
+
+## 🍰 How
+
+  - Discard all charset encoding table that could not fit the binary content.
+  - Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding.
+  - Extract matches with the lowest mess detected.
+  - Additionally, we measure coherence / probe for a language.
+
+**Wait a minute**, what is noise/mess and coherence according to **YOU ?**
+
+*Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then
+**I established** some ground rules about **what is obvious** when **it seems like** a mess (aka. defining noise in rendered text).
+ I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to
+ improve or rewrite it.
+
+*Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought
+that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design.
+
+## ⚡ Known limitations
+
+  - Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters))
+  - Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content.
+
+## ⚠️ About Python EOLs
+
+**If you are running:**
+
+- Python >=2.7,<3.5: Unsupported
+- Python 3.5: charset-normalizer < 2.1
+- Python 3.6: charset-normalizer < 3.1
+- Python 3.7: charset-normalizer < 4.0
+
+Upgrade your Python interpreter as soon as possible.

+"""
+Charset-Normalizer
+~~~~~~~~~~~~~~
+The Real First Universal Charset Detector.
+A library that helps you read text from an unknown charset encoding.
+Motivated by chardet, This package is trying to resolve the issue by taking a new approach.
+All IANA character set names for which the Python core library provides codecs are supported.
+
+Basic usage:
+   >>> from charset_normalizer import from_bytes
+   >>> results = from_bytes('Bсеки човек има право на образование. Oбразованието!'.encode('utf_8'))
+   >>> best_guess = results.best()
+   >>> str(best_guess)
+   'Bсеки човек има право на образование. Oбразованието!'
+
+Others methods and usages are available - see the full documentation
+at <https://github.com/Ousret/charset_normalizer>.

+# Click
+
+Click is a Python package for creating beautiful command line interfaces
+in a composable way with as little code as necessary. It's the "Command
+Line Interface Creation Kit". It's highly configurable but comes with
+sensible defaults out of the box.
+
+It aims to make the process of writing command line tools quick and fun
+while also preventing any frustration caused by the inability to
+implement an intended CLI API.
+
+Click in three points:
+
+-   Arbitrary nesting of commands
+-   Automatic help page generation
+-   Supports lazy loading of subcommands at runtime
+
+
+## A Simple Example
+
+```python
+import click
+
+@click.command()
+@click.option("--count", default=1, help="Number of greetings.")
+@click.option("--name", prompt="Your name", help="The person to greet.")
+def hello(count, name):
+    """Simple program that greets NAME for a total of COUNT times."""
+    for _ in range(count):
+        click.echo(f"Hello, {name}!")
+
+if __name__ == '__main__':
+    hello()
+```
+
+```
+$ python hello.py --count=3
+Your name: Click
+Hello, Click!
+Hello, Click!
+Hello, Click!
+```

+                      is the most descriptive name for the script or
+                      command.  For the toplevel script it is usually

+                               from environment variables is disabled.  This
+                               does not affect manually set environment
+                               variables which are always read.
+    :param default_map: a dictionary (like object) with default values
+                        for parameters.
+    :param terminal_width: the width of the terminal.  The default is
+                           inherit from parent context.  If no context
+                           defines the terminal width then auto

+                              pages).  This defaults to 80 characters if
+                              not overridden.  In other words: even if the
+                              terminal is larger than that, Click will not
+                              format things wider than 80 characters by
+                              default.  In addition to that, formatters might
+                              add some safety mapping on the right.
+    :param resilient_parsing: if this flag is enabled then Click will
+                              parse without any interactivity or callback
+                              invocation.  Default values will also be

+                              things such as completion support.
+    :param allow_extra_args: if this is set to `True` then extra arguments
+                             at the end will not raise an error and will be
+                             kept on the context.  The default is to inherit
+                             from the command.

+                                    and arguments cannot be mixed.  The
+                                    default is to inherit from the command.
+    :param ignore_unknown_options: instructs click to ignore options it does
+                                   not know and keeps them for later
+                                   processing.
+    :param help_option_names: optionally a list of strings that define how
+                              the default help parameter is named.  The
+                              default is ``['--help']``.

+                                 normalize tokens (options, choices,
+                                 etc.).  This for instance can be used to
+                                 implement case insensitive behavior.
+    :param color: controls if the terminal supports ANSI colors or not.  The
+                  default is autodetection.  This is only needed if ANSI
+                  codes are used in texts that Click prints which is by
+                  default not the case.  This for instance would affect
+                  help output.
+    :param show_default: Show the default value for commands. If this
+        value is not set, it defaults to the value from the parent
+        context. ``Command.show_default`` overrides this default for the
+        specific command.

+        this parameter. This can be a string or a sequence of strings. If a sequence is
+        given, only the first non-empty environment variable is used for the parameter.
+    :param shell_complete: A function that returns custom shell
+        completions. Used instead of the param's type completion if
+        given. Takes ``ctx, param, incomplete`` and must return a list
+        of :class:`~click.shell_completion.CompletionItem` or a list of

+                        its deprecation in --help. The message can be customized

+        ``process_value`` validates required parameters and bounded

+
+    .. versionchanged:: 8.0
+        Setting a default is no longer required for ``nargs>1``, it will

+        default to ``()``.
+
+    .. versionchanged:: 7.1
+        Empty environment variables are ignored rather than taking the

+    :param prompt: If set to ``True`` or a non empty string then the

+        without a value.
+    :param hide_input: If this is ``True`` then the input on the prompt

+This module started out as largely a copy paste from the stdlib's
+optparse module with the features removed that we do not need from
+optparse because we implement them in Click on a higher level (for
+instance type handling, help formatting and a lot more).
+
+The plan is to remove more and more from here over time.
+
+The reason this is a different module and not optparse from the stdlib
+is that there are differences in 2.x and 3.x about the error messages
+generated and optparse in the stdlib uses gettext for no good reason
+and might cause us issues.
+
+Click uses parts of optparse written by Gregory P. Ward and maintained
+by the Python Software Foundation. This is limited to code in parser.py.

+    """This function creates an iterable context manager that can be used
+    to iterate over something while showing a progress bar.  It will
+    either iterate over the `iterable` or `length` items (that are counted
+    up).  While iteration happens, this function will print a rendered
+    progress bar to the given `file` (defaults to stdout) and will attempt
+    to calculate remaining time and more.  By default, this progress bar
+    will not be rendered if the file is not a terminal.
+
+    The context manager creates the progress bar.  When the context
+    manager is entered the progress bar is already created.  With every
+    iteration over the progress bar, the iterable passed to the bar is
+    advanced and the bar is updated.  When the context manager exits,
+    a newline is printed and the progress bar is finalized on screen.
+
+    Note: The progress bar is currently designed for use cases where the
+    total progress can be expected to take at least several seconds.
+    Because of this, the ProgressBar class object won't display
+    progress that is considered too fast, and progress where the time
+    between steps is less than a second.
+
+    No printing must happen or the progress bar will be unintentionally
+    destroyed.
+
+    Example usage::
+
+        with progressbar(items) as bar:
+            for item in bar:
+                do_something_with(item)
+
+    Alternatively, if no iterable is specified, one can manually update the
+    progress bar through the `update()` method instead of directly
+    iterating over the progress bar.  The update method accepts the number
+    of steps to increment the bar with::
+
+        with progressbar(length=chunks.total_bytes) as bar:
+            for chunk in chunks:
+                process_chunk(chunk)
+                bar.update(chunks.bytes)
+
+    The ``update()`` method also takes an optional value specifying the
+    ``current_item`` at the new position. This is useful when used
+    together with ``item_show_func`` to customize the output for each
+    manual step::
+
+        with click.progressbar(
+            length=total_size,
+            label='Unzipping archive',
+            item_show_func=lambda a: a.filename
+        ) as bar:
+            for archive in zip_file:
+                archive.extract()
+                bar.update(archive.size, archive)
+
+    :param iterable: an iterable to iterate over.  If not provided the length
+                     is required.
+    :param length: the number of items to iterate over.  By default the
+                   progressbar will attempt to ask the iterator about its
+                   length, which might or might not work.  If an iterable is
+                   also provided this parameter can be used to override the
+                   length.  If an iterable is not provided the progress bar
+                   will iterate over a range of that length.
+    :param label: the label to show next to the progress bar.
+    :param hidden: hide the progressbar. Defaults to ``False``. When no tty is
+        detected, it will only print the progressbar label. Setting this to
+        ``False`` also disables that.
+    :param show_eta: enables or disables the estimated time display.  This is
+                     automatically disabled if the length cannot be
+                     determined.
+    :param show_percent: enables or disables the percentage display.  The
+                         default is `True` if the iterable has a length or
+                         `False` if not.
+    :param show_pos: enables or disables the absolute position display.  The
+                     default is `False`.
+    :param item_show_func: A function called with the current item which
+        can return a string to show next to the progress bar. If the
+        function returns ``None`` nothing is shown. The current item can
+        be ``None``, such as when entering and exiting the bar.
+    :param fill_char: the character to use to show the filled part of the
+                      progress bar.
+    :param empty_char: the character to use to show the non-filled part of
+                       the progress bar.
+    :param bar_template: the format string to use as template for the bar.
+                         The parameters in it are ``label`` for the label,
+                         ``bar`` for the progress bar and ``info`` for the
+                         info section.
+    :param info_sep: the separator between multiple info items (eta etc.)
+    :param width: the width of the progress bar in characters, 0 means full
+                  terminal width
+    :param file: The file to write to. If this is not a terminal then
+        only the label is printed.
+    :param color: controls if the terminal supports ANSI colors or not.  The
+                  default is autodetection.  This is only needed if ANSI
+                  codes are included anywhere in the progress bar output
+                  which is not the case by default.
+    :param update_min_steps: Render only when this many updates have
+        completed. This allows tuning for very fast iterators.

+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+Distro - an OS platform information API

+
+`distro` provides information about the
+OS distribution it runs on, such as a reliable machine-readable ID, or
+version information.
+
+It is the recommended replacement for Python's original
+[`platform.linux_distribution`](https://docs.python.org/3.7/library/platform.html#platform.linux_distribution)
+function (removed in Python 3.8). It also provides much more functionality
+which isn't necessarily Python bound, like a command-line interface.
+
+Distro currently supports Linux and BSD based systems but [Windows and OS X support](https://github.com/python-distro/distro/issues/177) is also planned.
+
+For Python 2.6 support, see https://github.com/python-distro/distro/tree/python2.6-support
+
+## Installation
+
+Installation of the latest released version from PyPI:
+
+```shell
+pip install distro
+```
+
+Installation of the latest development version:
+
+```shell
+pip install https://github.com/python-distro/distro/archive/master.tar.gz
+```
+
+To use as a standalone script, download `distro.py` directly:
+
+```shell
+curl -O https://raw.githubusercontent.com/python-distro/distro/master/src/distro/distro.py
+python distro.py
+```
+
+``distro`` is safe to vendor within projects that do not wish to add
+dependencies.
+
+```shell
+cd myproject
+curl -O https://raw.githubusercontent.com/python-distro/distro/master/src/distro/distro.py
+```
+
+## Usage
+
+```bash
+$ distro
+Name: Antergos Linux
+Version: 2015.10 (ISO-Rolling)
+Codename: ISO-Rolling
+
+$ distro -j
+{
+    "codename": "ISO-Rolling",
+    "id": "antergos",
+    "like": "arch",
+    "version": "16.9",
+    "version_parts": {
+        "build_number": "",
+        "major": "16",
+        "minor": "9"
+    }
+}
+
+
+$ python
+>>> import distro
+>>> distro.name(pretty=True)
+'CentOS Linux 8'
+>>> distro.id()
+'centos'
+>>> distro.version(best=True)
+'8.4.2105'
+```
+
+
+## Documentation
+
+On top of the aforementioned API, several more functions are available. For a complete description of the
+API, see the [latest API documentation](http://distro.readthedocs.org/en/latest/).
+
+## Background
+
+An alternative implementation became necessary because Python 3.5 deprecated
+this function, and Python 3.8 removed it altogether. Its predecessor function
+[`platform.dist`](https://docs.python.org/3.7/library/platform.html#platform.dist)
+was already deprecated since Python 2.6 and removed in Python 3.8. Still, there
+are many cases in which access to that information is needed. See [Python issue
+1322](https://bugs.python.org/issue1322) for more information.
+
+The `distro` package implements a robust and inclusive way of retrieving the
+information about a distribution based on new standards and old methods,
+namely from these data sources (from high to low precedence):
+
+* The os-release file `/etc/os-release` if present, with a fall-back on `/usr/lib/os-release` if needed.
+* The output of the `lsb_release` command, if available.
+* The distro release file (`/etc/*(-|_)(release|version)`), if present.
+* The `uname` command for BSD based distrubtions.
+
+
+## Python and Distribution Support
+
+`distro` is supported and tested on Python 3.6+ and PyPy and on any
+distribution that provides one or more of the data sources covered.
+
+This package is tested with test data that mimics the exact behavior of the data sources of [a number of Linux distributions](https://github.com/python-distro/distro/tree/master/tests/resources/distros).
+
+
+## Testing
+
+```shell
+git clone git@github.com:python-distro/distro.git
+cd distro
+pip install tox
+tox
+```
+
+
+## Contributions
+
+Pull requests are always welcome to deal with specific distributions or just
+for general merriment.
+
+See [CONTRIBUTIONS](https://github.com/python-distro/distro/blob/master/CONTRIBUTING.md) for contribution info.

+formats can be found here:

+The ``distro`` package (``distro`` stands for Linux Distribution) provides
+information about the Linux distribution it runs on, such as a reliable
+machine-readable distro ID, or version information.
+
+It is the recommended replacement for Python's original
+:py:func:`platform.linux_distribution` function, but it provides much more
+functionality. An alternative implementation became necessary because Python
+3.5 deprecated this function, and Python 3.8 removed it altogether. Its
+predecessor function :py:func:`platform.dist` was already deprecated since
+Python 2.6 and removed in Python 3.8. Still, there are many cases in which
+access to OS distribution information is needed. See `Python issue 1322
+<https://bugs.python.org/issue1322>`_ for more information.

+Flask
+=====
+
+Flask is a lightweight `WSGI`_ web application framework. It is designed
+to make getting started quick and easy, with the ability to scale up to
+complex applications. It began as a simple wrapper around `Werkzeug`_
+and `Jinja`_ and has become one of the most popular Python web
+application frameworks.
+
+Flask offers suggestions, but doesn't enforce any dependencies or
+project layout. It is up to the developer to choose the tools and
+libraries they want to use. There are many extensions provided by the
+community that make adding new functionality easy.

+    """The flask object implements a WSGI application and acts as the central
+    object.  It is passed the name of the module or package of the
+    application.  Once it is created it will act as a central registry for
+    the view functions, the URL rules, template configuration and much more.
+
+    The name of the package is used to resolve resources from inside the
+    package or the folder the module is contained in depending on if the
+    package parameter resolves to an actual python package (a folder with
+    an :file:`__init__.py` file inside) or a standard module (just a ``.py`` file).
+
+    For more information about resource loading, see :func:`open_resource`.
+
+    Usually you create a :class:`Flask` instance in your main module or
+    in the :file:`__init__.py` file of your package like this::
+
+        from flask import Flask
+        app = Flask(__name__)
+
+    .. admonition:: About the First Parameter
+
+        The idea of the first parameter is to give Flask an idea of what
+        belongs to your application.  This name is used to find resources
+        on the filesystem, can be used by extensions to improve debugging
+        information and a lot more.
+
+        So it's important what you provide there.  If you are using a single
+        module, `__name__` is always the correct value.  If you however are
+        using a package, it's usually recommended to hardcode the name of
+        your package there.
+
+        For example if your application is defined in :file:`yourapplication/app.py`
+        you should create it with one of the two versions below::
+
+            app = Flask('yourapplication')
+            app = Flask(__name__.split('.')[0])
+
+        Why is that?  The application will work even with `__name__`, thanks
+        to how resources are looked up.  However it will make debugging more
+        painful.  Certain extensions can make assumptions based on the
+        import name of your application.  For example the Flask-SQLAlchemy
+        extension will look for the code in your application that triggered
+        an SQL query in debug mode.  If the import name is not properly set
+        up, that debugging information is lost.  (For example it would only
+        pick up SQL queries in `yourapplication.app` and not
+        `yourapplication.views.frontend`)

+    :param static_folder: The folder with static files that is served at
+        ``static_url_path``. Relative to the application ``root_path``
+        or an absolute path. Defaults to ``'static'``.
+    :param static_host: the host to use when adding the static route.
+        Defaults to None. Required when using ``host_matching=True``
+        with a ``static_folder`` configured.
+    :param host_matching: set ``url_map.host_matching`` attribute.
+        Defaults to False.
+    :param subdomain_matching: consider the subdomain relative to
+        :data:`SERVER_NAME` when matching routes. Defaults to False.
+    :param template_folder: the folder that contains the templates that should
+                            be used by the application.  Defaults to
+                            ``'templates'`` folder in the root path of the
+                            application.
+    :param instance_path: An alternative instance path for the application.
+                          By default the folder ``'instance'`` next to the
+                          package or module is assumed to be the instance
+                          path.
+    :param instance_relative_config: if set to ``True`` relative filenames
+                                     for loading the config are assumed to
+                                     be relative to the instance path instead
+                                     of the application root.
+    :param root_path: The path to the root of the application files.
+        This should only be set manually when it can't be detected
+        automatically, such as for namespace packages.

+        of the context until the end of the ``with`` block.  This is useful if
+        you want to access the context locals for testing::
+
+            with app.test_client() as c:
+                rv = c.get('/?vodka=42')
+                assert request.args['vodka'] == '42'
+
+        Additionally, you may pass optional keyword arguments that will then
+        be passed to the application's :attr:`test_client_class` constructor.
+        For example::
+
+            from flask.testing import FlaskClient

+    app-related functions that can be registered on a real application
+    later.
+
+    A blueprint is an object that allows defining application functions
+    without requiring an application object ahead of time. It uses the
+    same decorators as :class:`~flask.Flask`, but defers the need for an
+    application by recording them for later registration.
+
+    Decorating a function with a blueprint creates a deferred function
+    that is called with :class:`~flask.blueprints.BlueprintSetupState`
+    when the blueprint is registered on an application.
+
+    See :doc:`/blueprints` for more information.
+
+    :param name: The name of the blueprint. Will be prepended to each
+        endpoint name.
+    :param import_name: The name of the blueprint package, usually
+        ``__name__``. This helps locate the ``root_path`` for the
+        blueprint.
+    :param static_folder: A folder with static files that should be
+        served by the blueprint's static route. The path is relative to
+        the blueprint's root path. Blueprint static files are disabled
+        by default.
+    :param static_url_path: The url to serve static files from.
+        Defaults to ``static_folder``. If the blueprint does not have
+        a ``url_prefix``, the app's static route will take precedence,
+        and the blueprint's static files won't be accessible.
+    :param template_folder: A folder with templates that should be added
+        to the app's template search path. The path is relative to the
+        blueprint's root path. Blueprint templates are disabled by
+        default. Blueprint templates have a lower precedence than those
+        in the app's templates folder.
+    :param url_prefix: A path to prepend to all of the blueprint's URLs,
+        to make them distinct from the rest of the app's routes.
+    :param subdomain: A subdomain that blueprint routes will match on by
+        default.
+    :param url_defaults: A dict of default values that blueprint routes
+        will receive by default.
+    :param root_path: By default, the blueprint will automatically set
+        this based on ``import_name``. In certain situations this
+        automatic detection can fail, so the path can be specified
+        manually instead.

+
+    Either you can fill the config from a config file::
+
+        app.config.from_pyfile('yourconfig.cfg')
+
+    Or alternatively you can define the configuration options in the
+    module that calls :meth:`from_object` or provide an import path to
+    a module that should be loaded.  It is also possible to tell it to
+    use the same module and with that provide the configuration values
+    just before the call::
+
+        DEBUG = True
+        SECRET_KEY = 'development key'
+        app.config.from_object(__name__)
+
+    In both cases (loading from any Python file or loading from modules),
+    only uppercase keys are added to the config.  This makes it possible to use
+    lowercase values in the config file for temporary values that are not added
+    to the config or to define the config keys in the same file that implements
+    the application.
+
+    Probably the most interesting way to load configurations is from an
+    environment variable pointing to a file::
+
+        app.config.from_envvar('YOURAPPLICATION_SETTINGS')
+
+    In this case before launching the application you have to set this
+    environment variable to the file you want to use.  On Linux and OS X
+    use the export statement::
+
+        export YOURAPPLICATION_SETTINGS='/path/to/config/file'

+
+    The first argument can be a file path or a file-like object. Paths
+    are preferred in most cases because Werkzeug can manage the file and
+    get extra information from the path. Passing a file-like object
+    requires that the file is opened in binary mode, and is mostly
+    useful when building a file in memory with :class:`io.BytesIO`.
+
+    Never pass file paths provided by a user. The path is assumed to be
+    trusted, so a user could craft a path to access a file you didn't
+    intend. Use :func:`send_from_directory` to safely serve
+    user-requested paths from within a directory.
+
+    If the WSGI server sets a ``file_wrapper`` in ``environ``, it is
+    used, otherwise Werkzeug's built-in wrapper is used. Alternatively,
+    if the HTTP server supports ``X-Sendfile``, configuring Flask with
+    ``USE_X_SENDFILE = True`` will tell the server to send the given
+    path, which is much more efficient than reading it in Python.

+        Alternatively, a file-like object opened in binary mode. Make
+        sure the file pointer is seeked to the start of the data.
+    :param mimetype: The MIME type to send for the file. If not
+        provided, it will try to detect it from the file name.
+    :param as_attachment: Indicate to a browser that it should offer to
+        save the file instead of displaying it.
+    :param download_name: The default name browsers will use when saving
+        the file. Defaults to the passed file name.
+    :param conditional: Enable conditional and range responses based on
+        request headers. Requires passing a file path and ``environ``.
+    :param etag: Calculate an ETag for the file, which requires passing
+        a file path. Can also be a string to use instead.
+    :param last_modified: The last modified time to send for the file,
+        in seconds. If not provided, it will try to detect it from the
+        file path.
+    :param max_age: How long the client should cache the file, in

+    will complain that the secret key was not set.

+   :alt: Documentation Status
+
+This is a little HTTP/1.1 library written from scratch in Python,
+heavily inspired by `hyper-h2 <https://hyper-h2.readthedocs.io/>`_.
+
+It's a "bring-your-own-I/O" library; h11 contains no IO code
+whatsoever. This means you can hook h11 up to your favorite network
+API, and that could be anything you want: synchronous, threaded,
+asynchronous, or your own implementation of `RFC 6214
+<https://tools.ietf.org/html/rfc6214>`_ -- h11 won't judge you.
+(Compare this to the current state of the art, where every time a `new
+network API <https://trio.readthedocs.io/>`_ comes along then someone
+gets to start over reimplementing the entire HTTP protocol from
+scratch.) Cory Benfield made an `excellent blog post describing the
+benefits of this approach
+<https://lukasa.co.uk/2015/10/The_New_Hyper/>`_, or if you like video
+then here's his `PyCon 2016 talk on the same theme
+<https://www.youtube.com/watch?v=7cC3_jGwl_U>`_.
+
+This also means that h11 is not immediately useful out of the box:
+it's a toolkit for building programs that speak HTTP, not something
+that could directly replace ``requests`` or ``twisted.web`` or
+whatever. But h11 makes it much easier to implement something like
+``requests`` or ``twisted.web``.
+
+At a high level, working with h11 goes like this:
+
+1) First, create an ``h11.Connection`` object to track the state of a
+   single HTTP/1.1 connection.
+
+2) When you read data off the network, pass it to
+   ``conn.receive_data(...)``; you'll get back a list of objects
+   representing high-level HTTP "events".
+
+3) When you want to send a high-level HTTP event, create the
+   corresponding "event" object and pass it to ``conn.send(...)``;
+   this will give you back some bytes that you can then push out
+   through the network.
+
+For example, a client might instantiate and then send a
+``h11.Request`` object, then zero or more ``h11.Data`` objects for the
+request body (e.g., if this is a POST), and then a
+``h11.EndOfMessage`` to indicate the end of the message. Then the
+server would then send back a ``h11.Response``, some ``h11.Data``, and
+its own ``h11.EndOfMessage``. If either side violates the protocol,
+you'll get a ``h11.ProtocolError`` exception.
+
+h11 is suitable for implementing both servers and clients, and has a
+pleasantly symmetric API: the events you send as a client are exactly
+the ones that you receive as a server and vice-versa.
+
+`Here's an example of a tiny HTTP client
+<https://github.com/python-hyper/h11/blob/master/examples/basic-client.py>`_
+
+It also has `a fine manual <https://h11.readthedocs.io/>`_.
+
+FAQ
+---
+
+*Whyyyyy?*
+
+I wanted to play with HTTP in `Curio
+<https://curio.readthedocs.io/en/latest/tutorial.html>`__ and `Trio
+<https://trio.readthedocs.io>`__, which at the time didn't have any
+HTTP libraries. So I thought, no big deal, Python has, like, a dozen
+different implementations of HTTP, surely I can find one that's
+reusable. I didn't find one, but I did find Cory's call-to-arms
+blog-post. So I figured, well, fine, if I have to implement HTTP from
+scratch, at least I can make sure no-one *else* has to ever again.
+
+*Should I use it?*
+
+Maybe. You should be aware that it's a very young project. But, it's
+feature complete and has an exhaustive test-suite and complete docs,
+so the next step is for people to try using it and see how it goes
+:-). If you do then please let us know -- if nothing else we'll want
+to talk to you before making any incompatible changes!
+
+*What are the features/limitations?*
+
+Roughly speaking, it's trying to be a robust, complete, and non-hacky
+implementation of the first "chapter" of the HTTP/1.1 spec: `RFC 7230:
+HTTP/1.1 Message Syntax and Routing
+<https://tools.ietf.org/html/rfc7230>`_. That is, it mostly focuses on
+implementing HTTP at the level of taking bytes on and off the wire,
+and the headers related to that, and tries to be anal about spec
+conformance. It doesn't know about higher-level concerns like URL
+routing, conditional GETs, cross-origin cookie policies, or content
+negotiation. But it does know how to take care of framing,
+cross-version differences in keep-alive handling, and the "obsolete
+line folding" rule, so you can focus your energies on the hard /
+interesting parts for your application, and it tries to support the
+full specification in the sense that any useful HTTP/1.1 conformant
+application should be able to use h11.
+
+It's pure Python, and has no dependencies outside of the standard
+library.
+
+It has a test suite with 100.0% coverage for both statements and
+branches.
+
+Currently it supports Python 3 (testing on 3.8-3.12) and PyPy 3.
+The last Python 2-compatible version was h11 0.11.x.
+(Originally it had a Cython wrapper for `http-parser
+<https://github.com/nodejs/http-parser>`_ and a beautiful nested state
+machine implemented with ``yield from`` to postprocess the output. But
+I had to take these out -- the new *parser* needs fewer lines-of-code
+than the old *parser wrapper*, is written in pure Python, uses no
+exotic language syntax, and has more features. It's sad, really; that
+old state machine was really slick. I just need a few sentences here
+to mourn that.)
+
+I don't know how fast it is. I haven't benchmarked or profiled it yet,
+so it's probably got a few pointless hot spots, and I've been trying
+to err on the side of simplicity and robustness instead of
+micro-optimization. But at the architectural level I tried hard to
+avoid fundamentally bad decisions, e.g., I believe that all the
+parsing algorithms remain linear-time even in the face of pathological
+input like slowloris, and there are no byte-by-byte loops. (I also
+believe that it maintains bounded memory usage in the face of
+arbitrary/pathological input.)
+
+The whole library is ~800 lines-of-code. You can read and understand
+the whole thing in less than an hour. Most of the energy invested in
+this so far has been spent on trying to keep things simple by
+minimizing special-cases and ad hoc state manipulation; even though it
+is now quite small and simple, I'm still annoyed that I haven't
+figured out how to make it even smaller and simpler. (Unfortunately,
+HTTP does not lend itself to simplicity.)
+
+The API is ~feature complete and I don't expect the general outlines
+to change much, but you can't judge an API's ergonomics until you
+actually document and use it, so I'd expect some changes in the
+details.
+
+*How do I try it?*
+
+.. code-block:: sh
+
+  $ pip install h11
+  $ git clone git@github.com:python-hyper/h11
+  $ cd h11/examples
+  $ python basic-client.py
+
+and go from there.

+# Facts
+# -----
+#
+# Headers are:
+#   keys: case-insensitive ascii
+#   values: mixture of ascii and raw bytes
+#
+# "Historically, HTTP has allowed field content with text in the ISO-8859-1
+# charset [ISO-8859-1], supporting other charsets only through use of
+# [RFC2047] encoding.  In practice, most HTTP header field values use only a
+# subset of the US-ASCII charset [USASCII]. Newly defined header fields SHOULD
+# limit their field values to US-ASCII octets.  A recipient SHOULD treat other
+# octets in field content (obs-text) as opaque data."
+# And it deprecates all non-ascii values
+#
+# Leading/trailing whitespace in header names is forbidden
+#
+# Values get leading/trailing whitespace stripped
+#
+# Content-Disposition actually needs to contain unicode semantically; to
+# accomplish this it has a terrifically weird way of encoding the filename
+# itself as ascii (and even this still has lots of cross-browser
+# incompatibilities)
+#
+# Order is important:
+# "a proxy MUST NOT change the order of these field values when forwarding a
+# message"
+# (and there are several headers where the order indicates a preference)
+#
+# Multiple occurences of the same header:
+# "A sender MUST NOT generate multiple header fields with the same field name
+# in a message unless either the entire field value for that header field is
+# defined as a comma-separated list [or the header is Set-Cookie which gets a
+# special exception]" - RFC 7230. (cookies are in RFC 6265)
+#
+# So every header aside from Set-Cookie can be merged by b", ".join if it
+# occurs repeatedly. But, of course, they can't necessarily be split by
+# .split(b","), because quoting.
+#
+# Given all this mess (case insensitive, duplicates allowed, order is
+# important, ...), there doesn't appear to be any standard way to handle
+# headers in Python -- they're almost like dicts, but... actually just
+# aren't. For now we punt and just use a super simple representation: headers
+# are a list of pairs
+#
+#   [(name1, value1), (name2, value2), ...]
+#
+# where all entries are bytestrings, names are lowercase and have no
+# leading/trailing whitespace, and values are bytestrings with no
+# leading/trailing whitespace. Searching and updating are done via naive O(n)
+# methods.
+#
+# Maybe a dict-of-lists would be better?

+# ===================
+#
+# Possibly the simplest way to think about this is that we actually have 5
+# different state machines here. Yes, 5. These are:
+#
+# 1) The client state, with its complicated automaton (see the docs)
+# 2) The server state, with its complicated automaton (see the docs)
+# 3) The keep-alive state, with possible states {True, False}
+# 4) The SWITCH_CONNECT state, with possible states {False, True}
+# 5) The SWITCH_UPGRADE state, with possible states {False, True}
+#
+# For (3)-(5), the first state listed is the initial state.
+#
+# (1)-(3) are stored explicitly in member variables. The last
+# two are stored implicitly in the pending_switch_proposals set as:
+#   (state of 4) == (_SWITCH_CONNECT in pending_switch_proposals)
+#   (state of 5) == (_SWITCH_UPGRADE in pending_switch_proposals)
+#
+# And each of these machines has two different kinds of transitions:
+#
+# a) Event-triggered
+# b) State-triggered
+#
+# Event triggered is the obvious thing that you'd think it is: some event
+# happens, and if it's the right event at the right time then a transition
+# happens. But there are somewhat complicated rules for which machines can
+# "see" which events. (As a rule of thumb, if a machine "sees" an event, this
+# means two things: the event can affect the machine, and if the machine is
+# not in a state where it expects that event then it's an error.) These rules
+# are:
+#
+# 1) The client machine sees all h11.events objects emitted by the client.
+#
+# 2) The server machine sees all h11.events objects emitted by the server.
+#
+#    It also sees the client's Request event.
+#
+#    And sometimes, server events are annotated with a _SWITCH_* event. For
+#    example, we can have a (Response, _SWITCH_CONNECT) event, which is
+#    different from a regular Response event.
+#
+# 3) The keep-alive machine sees the process_keep_alive_disabled() event
+#    (which is derived from Request/Response events), and this event
+#    transitions it from True -> False, or from False -> False. There's no way
+#    to transition back.
+#
+# 4&5) The _SWITCH_* machines transition from False->True when we get a
+#    Request that proposes the relevant type of switch (via
+#    process_client_switch_proposals), and they go from True->False when we
+#    get a Response that has no _SWITCH_* annotation.
+#
+# So that's event-triggered transitions.
+#
+# State-triggered transitions are less standard. What they do here is couple
+# the machines together. The way this works is, when certain *joint*
+# configurations of states are achieved, then we automatically transition to a
+# new *joint* state. So, for example, if we're ever in a joint state with
+#
+#   client: DONE
+#   keep-alive: False
+#
+# then the client state immediately transitions to:
+#
+#   client: MUST_CLOSE
+#
+# This is fundamentally different from an event-based transition, because it
+# doesn't matter how we arrived at the {client: DONE, keep-alive: False} state
+# -- maybe the client transitioned SEND_BODY -> DONE, or keep-alive
+# transitioned True -> False. Either way, once this precondition is satisfied,
+# this transition is immediately triggered.
+#
+# What if two conflicting state-based transitions get enabled at the same
+# time?  In practice there's only one case where this arises (client DONE ->
+# MIGHT_SWITCH_PROTOCOL versus DONE -> MUST_CLOSE), and we resolve it by
+# explicitly prioritizing the DONE -> MIGHT_SWITCH_PROTOCOL transition.
+#
+# Implementation
+# --------------
+#
+# The event-triggered transitions for the server and client machines are all
+# stored explicitly in a table. Ditto for the state-triggered transitions that
+# involve just the server and client state.
+#
+# The transitions for the other machines, and the state-triggered transitions
+# that involve the other machines, are written out as explicit Python code.
+#
+# It'd be nice if there were some cleaner way to do all this. This isn't
+# *too* terrible, but I feel like it could probably be better.
+#
+# WARNING
+# -------
+#
+# The script that generates the state machine diagrams for the docs knows how
+# to read out the EVENT_TRIGGERED_TRANSITIONS and STATE_TRIGGERED_TRANSITIONS
+# tables. But it can't automatically read the transitions that are written
+# directly in Python code. So if you touch those, you need to also update the
+# script to keep it in sync!

+# HTTP Core
+
+[![Test Suite](https://github.com/encode/httpcore/workflows/Test%20Suite/badge.svg)](https://github.com/encode/httpcore/actions)
+[![Package version](https://badge.fury.io/py/httpcore.svg)](https://pypi.org/project/httpcore/)
+
+> *Do one thing, and do it well.*
+
+The HTTP Core package provides a minimal low-level HTTP client, which does
+one thing only. Sending HTTP requests.
+
+It does not provide any high level model abstractions over the API,
+does not handle redirects, multipart uploads, building authentication headers,
+transparent HTTP caching, URL parsing, session cookie handling,
+content or charset decoding, handling JSON, environment based configuration
+defaults, or any of that Jazz.
+
+Some things HTTP Core does do:
+
+* Sending HTTP requests.
+* Thread-safe / task-safe connection pooling.
+* HTTP(S) proxy & SOCKS proxy support.
+* Supports HTTP/1.1 and HTTP/2.
+* Provides both sync and async interfaces.
+* Async backend support for `asyncio` and `trio`.
+
+## Requirements
+
+Python 3.8+
+
+## Installation
+
+For HTTP/1.1 only support, install with:
+
+```shell
+$ pip install httpcore
+```
+
+There are also a number of optional extras available...
+
+```shell
+$ pip install httpcore['asyncio,trio,http2,socks']
+```
+
+## Sending requests
+
+Send an HTTP request:
+
+```python
+import httpcore
+
+response = httpcore.request("GET", "https://www.example.com/")
+
+print(response)
+# <Response [200]>
+print(response.status)
+# 200
+print(response.headers)
+# [(b'Accept-Ranges', b'bytes'), (b'Age', b'557328'), (b'Cache-Control', b'max-age=604800'), ...]
+print(response.content)
+# b'<!doctype html>\n<html>\n<head>\n<title>Example Domain</title>\n\n<meta charset="utf-8"/>\n ...'
+```
+
+The top-level `httpcore.request()` function is provided for convenience. In practice whenever you're working with `httpcore` you'll want to use the connection pooling functionality that it provides.
+
+```python
+import httpcore
+
+http = httpcore.ConnectionPool()
+response = http.request("GET", "https://www.example.com/")
+```
+
+Once you're ready to get going, [head over to the documentation](https://www.encode.io/httpcore/).
+
+## Motivation
+
+You *probably* don't want to be using HTTP Core directly. It might make sense if
+you're writing something like a proxy service in Python, and you just want
+something at the lowest possible level, but more typically you'll want to use
+a higher level client library, such as `httpx`.
+
+The motivation for `httpcore` is:
+
+* To provide a reusable low-level client library, that other packages can then build on top of.
+* To provide a *really clear interface split* between the networking code and client logic,
+  so that each is easier to understand and reason about in isolation.
+
+## Dependencies
+
+The `httpcore` package has the following dependencies...
+
+* `h11`
+* `certifi`
+
+And the following optional extras...
+
+* `anyio` - Required by `pip install httpcore['asyncio']`.
+* `trio` - Required by `pip install httpcore['trio']`.
+* `h2` - Required by `pip install httpcore['http2']`.
+* `socksio` - Required by `pip install httpcore['socks']`.
+

+## 0.14.1 (November 12th, 2021)
+
+- `max_connections` becomes optional. (Pull #429)
+- `certifi` is now included in the install dependancies. (Pull #428)
+- `h2` is now strictly optional. (Pull #428)
+
+## 0.14.0 (November 11th, 2021)
+
+The 0.14 release is a complete reworking of `httpcore`, comprehensively addressing some underlying issues in the connection pooling, as well as substantially redesigning the API to be more user friendly.
+
+Some of the lower-level API design also makes the components more easily testable in isolation, and the package now has 100% test coverage.
+
+See [discussion #419](https://github.com/encode/httpcore/discussions/419) for a little more background.
+
+There's some other neat bits in there too, such as the "trace" extension, which gives a hook into inspecting the internal events that occur during the request/response cycle. This extension is needed for the HTTPX cli, in order to...
+
+* Log the point at which the connection is established, and the IP/port on which it is made.
+* Determine if the outgoing request should log as HTTP/1.1 or HTTP/2, rather than having to assume it's HTTP/2 if the --http2 flag was passed. (Which may not actually be true.)
+* Log SSL version info / certificate info.
+
+Note that `curio` support is not currently available in 0.14.0. If you're using `httpcore` with `curio` please get in touch, so we can assess if we ought to prioritize it as a feature or not.
+
+## 0.13.7 (September 13th, 2021)
+
+- Fix broken error messaging when URL scheme is missing, or a non HTTP(S) scheme is used. (Pull #403)
+
+## 0.13.6 (June 15th, 2021)
+
+### Fixed
+
+- Close sockets when read or write timeouts occur. (Pull #365)
+
+## 0.13.5 (June 14th, 2021)
+
+### Fixed
+
+- Resolved niggles with AnyIO EOF behaviours. (Pull #358, #362)
+
+## 0.13.4 (June 9th, 2021)
+
+### Added
+
+- Improved error messaging when URL scheme is missing, or a non HTTP(S) scheme is used. (Pull #354)
+
+### Fixed
+
+- Switched to `anyio` as the default backend implementation when running with `asyncio`. Resolves some awkward [TLS timeout issues](https://github.com/encode/httpx/discussions/1511).
+
+## 0.13.3 (May 6th, 2021)
+
+### Added
+
+- Support HTTP/2 prior knowledge, using `httpcore.SyncConnectionPool(http1=False)`. (Pull #333)
+
+### Fixed
+
+- Handle cases where environment does not provide `select.poll` support. (Pull #331)
+
+## 0.13.2 (April 29th, 2021)
+
+### Added
+
+- Improve error message for specific case of `RemoteProtocolError` where server disconnects without sending a response. (Pull #313)
+
+## 0.13.1 (April 28th, 2021)
+
+### Fixed
+
+- More resiliant testing for closed connections. (Pull #311)
+- Don't raise exceptions on ungraceful connection closes. (Pull #310)
+
+## 0.13.0 (April 21st, 2021)
+
+The 0.13 release updates the core API in order to match the HTTPX Transport API,
+introduced in HTTPX 0.18 onwards.
+
+An example of making requests with the new interface is:
+
+```python
+with httpcore.SyncConnectionPool() as http:
+    status_code, headers, stream, extensions = http.handle_request(
+        method=b'GET',
+        url=(b'https', b'example.org', 443, b'/'),
+        headers=[(b'host', b'example.org'), (b'user-agent', b'httpcore')]
+        stream=httpcore.ByteStream(b''),
+        extensions={}
+    )
+    body = stream.read()
+    print(status_code, body)
+```
+
+### Changed
+
+- The `.request()` method is now `handle_request()`. (Pull #296)
+- The `.arequest()` method is now `.handle_async_request()`. (Pull #296)
+- The `headers` argument is no longer optional. (Pull #296)
+- The `stream` argument is no longer optional. (Pull #296)
+- The `ext` argument is now named `extensions`, and is no longer optional. (Pull #296)
+- The `"reason"` extension keyword is now named `"reason_phrase"`. (Pull #296)
+- The `"reason_phrase"` and `"http_version"` extensions now use byte strings for their values. (Pull #296)
+- The `httpcore.PlainByteStream()` class becomes `httpcore.ByteStream()`. (Pull #296)
+
+### Added
+
+- Streams now support a `.read()` interface. (Pull #296)
+
+### Fixed
+
+- Task cancellation no longer leaks connections from the connection pool. (Pull #305)
+
+## 0.12.3 (December 7th, 2020)
+
+### Fixed
+

+
+## 0.11.0 (September 22nd, 2020)
+
+The Transport API with 0.11.0 has a couple of significant changes.
+
+Firstly we've moved changed the request interface in order to allow extensions, which will later enable us to support features
+such as trailing headers, HTTP/2 server push, and CONNECT/Upgrade connections.
+
+The interface changes from:
+
+```python
+def request(method, url, headers, stream, timeout):
+    return (http_version, status_code, reason, headers, stream)
+```
+
+To instead including an optional dictionary of extensions on the request and response:
+
+```python
+def request(method, url, headers, stream, ext):
+    return (status_code, headers, stream, ext)
+```
+
+Having an open-ended extensions point will allow us to add later support for various optional features, that wouldn't otherwise be supported without these API changes.
+
+In particular:
+
+* Trailing headers support.
+* HTTP/2 Server Push
+* sendfile.
+* Exposing raw connection on CONNECT, Upgrade, HTTP/2 bi-di streaming.
+* Exposing debug information out of the API, including template name, template context.
+
+Currently extensions are limited to:
+
+* request: `timeout` - Optional. Timeout dictionary.
+* response: `http_version` - Optional. Include the HTTP version used on the response.
+* response: `reason` - Optional. Include the reason phrase used on the response. Only valid with HTTP/1.*.
+
+See https://github.com/encode/httpx/issues/1274#issuecomment-694884553 for the history behind this.
+
+Secondly, the async version of `request` is now namespaced as `arequest`.
+
+This allows concrete transports to support both sync and async implementations on the same class.
+
+### Added
+
+- Add curio support. (Pull #168)
+- Add anyio support, with `backend="anyio"`. (Pull #169)
+
+### Changed
+
+- Update the Transport API to use 'ext' for optional extensions. (Pull #190)
+- Update the Transport API to use `.request` and `.arequest` so implementations can support both sync and async. (Pull #189)
+
+## 0.10.2 (August 20th, 2020)
+
+### Added
+
+- Added Unix Domain Socket support. (Pull #139)
+
+### Fixed
+
+- Always include the port on proxy CONNECT requests. (Pull #154)
+- Fix `max_keepalive_connections` configuration. (Pull #153)
+- Fixes behaviour in HTTP/1.1 where server disconnects can be used to signal the end of the response body. (Pull #164)
+
+## 0.10.1 (August 7th, 2020)
+
+- Include `max_keepalive_connections` on `AsyncHTTPProxy`/`SyncHTTPProxy` classes.
+
+## 0.10.0 (August 7th, 2020)
+
+The most notable change in the 0.10.0 release is that HTTP/2 support is now fully optional.
+
+Use either `pip install httpcore` for HTTP/1.1 support only, or `pip install httpcore[http2]` for HTTP/1.1 and HTTP/2 support.
+
+### Added
+
+- HTTP/2 support becomes optional. (Pull #121, #130)
+- Add `local_address=...` support. (Pull #100, #134)
+- Add `PlainByteStream`, `IteratorByteStream`, `AsyncIteratorByteStream`. The `AsyncByteSteam` and `SyncByteStream` classes are now pure interface classes. (#133)
+- Add `LocalProtocolError`, `RemoteProtocolError` exceptions. (Pull #129)
+- Add `UnsupportedProtocol` exception. (Pull #128)
+- Add `.get_connection_info()` method. (Pull #102, #137)
+- Add better TRACE logs. (Pull #101)
+
+### Changed
+
+- `max_keepalive` is deprecated in favour of `max_keepalive_connections`. (Pull #140)
+
+### Fixed
+
+- Improve handling of server disconnects. (Pull #112)
+
+## 0.9.1 (May 27th, 2020)
+
+### Fixed
+
+- Proper host resolution for sync case, including IPv6 support. (Pull #97)
+- Close outstanding connections when connection pool is closed. (Pull #98)
+
+## 0.9.0 (May 21th, 2020)
+
+### Changed
+
+- URL port becomes an `Optional[int]` instead of `int`. (Pull #92)
+
+### Fixed
+
+- Honor HTTP/2 max concurrent streams settings. (Pull #89, #90)
+- Remove incorrect debug log. (Pull #83)
+
+## 0.8.4 (May 11th, 2020)
+
+### Added
+
+- Logging via HTTPCORE_LOG_LEVEL and HTTPX_LOG_LEVEL environment variables
+and TRACE level logging. (Pull #79)
+
+### Fixed
+
+- Reuse of connections on HTTP/2 in close concurrency situations. (Pull #81)
+
+## 0.8.3 (May 6rd, 2020)
+
+### Fixed
+
+- Include `Host` and `Accept` headers on proxy "CONNECT" requests.
+- De-duplicate any headers also contained in proxy_headers.
+- HTTP/2 flag not being passed down to proxy connections.
+
+## 0.8.2 (May 3rd, 2020)
+
+### Fixed
+
+- Fix connections using proxy forwarding requests not being added to the
+connection pool properly. (Pull #70)
+
+## 0.8.1 (April 30th, 2020)
+
+### Changed
+
+- Allow inherintance of both `httpcore.AsyncByteStream`, `httpcore.SyncByteStream` without type conflicts.
+
+## 0.8.0 (April 30th, 2020)
+
+### Fixed
+
+- Fixed tunnel proxy support.

+    Represents the URL against which an HTTP request may be made.

+    The URL may either be specified as a plain string, for convienence:
+
+    ```python
+    url = httpcore.URL("https://www.example.com/")
+    ```
+
+    Or be constructed with explicitily pre-parsed components:
+
+    ```python
+    url = httpcore.URL(scheme=b'https', host=b'www.example.com', port=None, target=b'/')
+    ```
+
+    Using this second more explicit style allows integrations that are using
+    `httpcore` to pass through URLs that have already been parsed in order to use
+    libraries such as `rfc-3986` rather than relying on the stdlib. It also ensures
+    that URL parsing is treated identically at both the networking level and at any
+    higher layers of abstraction.
+
+    The four components are important here, as they allow the URL to be precisely
+    specified in a pre-parsed format. They also allow certain types of request to
+    be created that could not otherwise be expressed.
+
+    For example, an HTTP request to `http://www.example.com/` forwarded via a proxy
+    at `http://localhost:8080`...
+
+    ```python
+    # Constructs an HTTP request with a complete URL as the target:
+    # GET https://www.example.com/ HTTP/1.1
+    url = httpcore.URL(
+        scheme=b'http',
+        host=b'localhost',
+        port=8080,
+        target=b'https://www.example.com/'
+    )
+    request = httpcore.Request(
+        method="GET",
+        url=url
+    )
+    ```
+
+    Another example is constructing an `OPTIONS *` request...
+
+    ```python
+    # Constructs an 'OPTIONS *' HTTP request:
+    # OPTIONS * HTTP/1.1
+    url = httpcore.URL(scheme=b'https', host=b'www.example.com', target=b'*')
+    request = httpcore.Request(method="OPTIONS", url=url)
+    ```
+
+    This kind of request is not possible to formulate with a URL string,
+    because the `/` delimiter is always used to demark the target from the
+    host/port portion of the URL.

+    For convenience, string-like arguments may be specified either as strings or
+    as bytes. However, once a request is being issue over-the-wire, the URL
+    components are always ultimately required to be a bytewise representation.
+
+    In order to avoid any ambiguity over character encodings, when strings are used
+    as arguments, they must be strictly limited to the ASCII range `chr(0)`-`chr(127)`.
+    If you require a bytewise representation that is outside this range you must
+    handle the character encoding directly, and pass a bytes instance.

+
+HTTPX is a fully featured HTTP client library for Python 3. It includes **an integrated command line client**, has support for both **HTTP/1.1 and HTTP/2**, and provides both **sync and async APIs**.
+
+---
+
+Install HTTPX using pip:
+
+```shell
+$ pip install httpx
+```
+
+Now, let's get started:
+
+```pycon
+>>> import httpx
+>>> r = httpx.get('https://www.example.org/')
+>>> r
+<Response [200 OK]>
+>>> r.status_code
+200
+>>> r.headers['content-type']
+'text/html; charset=UTF-8'
+>>> r.text
+'<!doctype html>\n<html>\n<head>\n<title>Example Domain</title>...'
+```
+
+Or, using the command-line client.
+
+```shell
+$ pip install 'httpx[cli]'  # The command line client is an optional dependency.
+```
+
+Which now allows us to use HTTPX directly from the command-line...

+
+## Features
+
+HTTPX builds on the well-established usability of `requests`, and gives you:
+
+* A broadly [requests-compatible API](https://www.python-httpx.org/compatibility/).
+* An integrated command-line client.
+* HTTP/1.1 [and HTTP/2 support](https://www.python-httpx.org/http2/).
+* Standard synchronous interface, but with [async support if you need it](https://www.python-httpx.org/async/).
+* Ability to make requests directly to [WSGI applications](https://www.python-httpx.org/advanced/transports/#wsgi-transport) or [ASGI applications](https://www.python-httpx.org/advanced/transports/#asgi-transport).
+* Strict timeouts everywhere.
+* Fully type annotated.
+* 100% test coverage.
+
+Plus all the standard features of `requests`...

+
+## Documentation
+
+Project documentation is available at [https://www.python-httpx.org/](https://www.python-httpx.org/).
+
+For a run-through of all the basics, head over to the [QuickStart](https://www.python-httpx.org/quickstart/).
+
+For more advanced topics, see the [Advanced Usage](https://www.python-httpx.org/advanced/) section, the [async support](https://www.python-httpx.org/async/) section, or the [HTTP/2](https://www.python-httpx.org/http2/) section.
+
+The [Developer Interface](https://www.python-httpx.org/api/) provides a comprehensive API reference.

+## Contribute
+
+If you want to contribute with HTTPX check out the [Contributing Guide](https://www.python-httpx.org/contributing/) to learn how to start.
+
+## Dependencies
+
+The HTTPX project relies on these excellent libraries:
+
+* `httpcore` - The underlying transport implementation for `httpx`.
+  * `h11` - HTTP/1.1 support.
+* `certifi` - SSL certificates.
+* `idna` - Internationalized domain name support.
+* `sniffio` - Async library autodetection.
+
+As well as these optional installs:
+
+* `h2` - HTTP/2 support. *(Optional, with `httpx[http2]`)*
+* `socksio` - SOCKS proxy support. *(Optional, with `httpx[socks]`)*
+* `rich` - Rich terminal support. *(Optional, with `httpx[cli]`)*
+* `click` - Command line client support. *(Optional, with `httpx[cli]`)*
+* `brotli` or `brotlicffi` - Decoding for "brotli" compressed responses. *(Optional, with `httpx[brotli]`)*
+* `zstandard` - Decoding for "zstd" compressed responses. *(Optional, with `httpx[zstd]`)*
+
+A huge amount of credit is due to `requests` for the API layout that
+much of this work follows, as well as to `urllib3` for plenty of design
+inspiration around the lower-level networking details.

+    **Parameters:**
+
+    * **auth** - *(optional)* An authentication class to use when sending

+    * **params** - *(optional)* Query parameters to include in request URLs, as
+    a string, dictionary, or sequence of two-tuples.
+    * **headers** - *(optional)* Dictionary of HTTP headers to include when
+    sending requests.
+    * **cookies** - *(optional)* Dictionary of Cookie items to include when
+    sending requests.
+    * **verify** - *(optional)* Either `True` to use an SSL context with the
+    default CA bundle, `False` to disable verification, or an instance of
+    `ssl.SSLContext` to use a custom context.
+    * **http2** - *(optional)* A boolean indicating if HTTP/2 support should be

+    * **limits** - *(optional)* The limits configuration to use.
+    * **max_redirects** - *(optional)* The maximum number of redirect responses
+    that should be followed.
+    * **base_url** - *(optional)* A URL to use as the base when building
+    request URLs.
+    * **transport** - *(optional)* A transport class to use for sending requests
+    over the network.
+    * **trust_env** - *(optional)* Enables or disables usage of environment

+"""
+An implementation of `urlparse` that provides URL validation and normalization
+as described by RFC3986.
+
+We rely on this implementation rather than the one in Python's stdlib, because:
+
+* It provides more complete URL validation.
+* It properly differentiates between an empty querystring and an absent querystring,
+  to distinguish URLs with a trailing '?'.
+* It handles scheme, hostname, port, and path normalization.
+* It supports IDNA hostnames, normalizing them to their encoded form.
+* The API supports passing individual components, as well as the complete URL string.
+
+Previously we relied on the excellent `rfc3986` package to handle URL parsing and
+validation, but this module provides a simpler alternative, with less indirection
+required.

+Internationalized Domain Names in Applications (IDNA)
+=====================================================
+
+Support for `Internationalized Domain Names in
+Applications (IDNA) <https://tools.ietf.org/html/rfc5891>`_
+and `Unicode IDNA Compatibility Processing
+<https://unicode.org/reports/tr46/>`_.
+
+The latest versions of these standards supplied here provide
+more comprehensive language coverage and reduce the potential of
+allowing domains with known security vulnerabilities. This library
+is a suitable replacement for the “encodings.idna”
+module that comes with the Python standard library, but which
+only supports an older superseded IDNA specification from 2003.
+
+Basic functions are simply executed:
+
+.. code-block:: pycon
+
+    >>> import idna
+    >>> idna.encode('ドメイン.テスト')
+    b'xn--eckwd4c7c.xn--zckzah'
+    >>> print(idna.decode('xn--eckwd4c7c.xn--zckzah'))
+    ドメイン.テスト
+
+
+Installation
+------------
+
+This package is available for installation from PyPI via the
+typical mechanisms, such as:
+
+.. code-block:: bash
+
+    $ python3 -m pip install idna
+
+
+Usage
+-----
+
+For typical usage, the ``encode`` and ``decode`` functions will take a
+domain name argument and perform a conversion to ASCII compatible encoding
+(known as A-labels), or to Unicode strings (known as U-labels)
+respectively.
+
+.. code-block:: pycon
+
+    >>> import idna
+    >>> idna.encode('ドメイン.テスト')
+    b'xn--eckwd4c7c.xn--zckzah'
+    >>> print(idna.decode('xn--eckwd4c7c.xn--zckzah'))
+    ドメイン.テスト
+
+Conversions can be applied at a per-label basis using the ``ulabel`` or
+``alabel`` functions if necessary:
+
+.. code-block:: pycon
+
+    >>> idna.alabel('测试')
+    b'xn--0zwm56d'
+
+
+Compatibility Mapping (UTS #46)
++++++++++++++++++++++++++++++++
+
+This library provides support for `Unicode IDNA Compatibility
+Processing <https://unicode.org/reports/tr46/>`_ which normalizes input from
+different potential ways a user may input a domain prior to performing the IDNA
+conversion operations. This functionality, known as a 
+`mapping <https://tools.ietf.org/html/rfc5895>`_, is considered by the
+specification to be a local user-interface issue distinct from IDNA
+conversion functionality.
+
+For example, “Königsgäßchen” is not a permissible label as *LATIN
+CAPITAL LETTER K* is not allowed (nor are capital letters in general).
+UTS 46 will convert this into lower case prior to applying the IDNA
+conversion.
+
+.. code-block:: pycon
+
+    >>> import idna
+    >>> idna.encode('Königsgäßchen')
+    ...
+    idna.core.InvalidCodepoint: Codepoint U+004B at position 1 of 'Königsgäßchen' not allowed
+    >>> idna.encode('Königsgäßchen', uts46=True)
+    b'xn--knigsgchen-b4a3dun'
+    >>> print(idna.decode('xn--knigsgchen-b4a3dun'))
+    königsgäßchen
+
+
+Exceptions
+----------
+
+All errors raised during the conversion following the specification
+should raise an exception derived from the ``idna.IDNAError`` base
+class.
+
+More specific exceptions that may be generated as ``idna.IDNABidiError``
+when the error reflects an illegal combination of left-to-right and
+right-to-left characters in a label; ``idna.InvalidCodepoint`` when
+a specific codepoint is an illegal character in an IDN label (i.e.
+INVALID); and ``idna.InvalidCodepointContext`` when the codepoint is
+illegal based on its position in the string (i.e. it is CONTEXTO or CONTEXTJ
+but the contextual requirements are not satisfied.)
+
+Building and Diagnostics
+------------------------
+
+The IDNA and UTS 46 functionality relies upon pre-calculated lookup
+tables for performance. These tables are derived from computing against
+eligibility criteria in the respective standards using the command-line
+script ``tools/idna-data``.
+
+This tool will fetch relevant codepoint data from the Unicode repository
+and perform the required calculations to identify eligibility. There are
+three main modes:
+
+* ``idna-data make-libdata``. Generates ``idnadata.py`` and
+  ``uts46data.py``, the pre-calculated lookup tables used for IDNA and
+  UTS 46 conversions. Implementers who wish to track this library against
+  a different Unicode version may use this tool to manually generate a
+  different version of the ``idnadata.py`` and ``uts46data.py`` files.
+
+* ``idna-data make-table``. Generate a table of the IDNA disposition
+  (e.g. PVALID, CONTEXTJ, CONTEXTO) in the format found in Appendix
+  B.1 of RFC 5892 and the pre-computed tables published by `IANA
+  <https://www.iana.org/>`_.
+
+* ``idna-data U+0061``. Prints debugging output on the various
+  properties associated with an individual Unicode codepoint (in this
+  case, U+0061), that are used to assess the IDNA and UTS 46 status of a
+  codepoint. This is helpful in debugging or analysis.
+
+The tool accepts a number of arguments, described using ``idna-data
+-h``. Most notably, the ``--version`` argument allows the specification
+of the version of Unicode to be used in computing the table data. For
+example, ``idna-data --version 9.0.0 make-libdata`` will generate
+library data against Unicode 9.0.0.
+
+
+Additional Notes
+----------------
+
+* **Packages**. The latest tagged release version is published in the
+  `Python Package Index <https://pypi.org/project/idna/>`_.
+
+* **Version support**. This library supports Python 3.8 and higher.
+  As this library serves as a low-level toolkit for a variety of
+  applications, many of which strive for broad compatibility with older
+  Python versions, there is no rush to remove older interpreter support.
+  Support for older versions are likely to be removed from new releases
+  as automated tests can no longer easily be run, i.e. once the Python
+  version is officially end-of-life.
+
+* **Testing**. The library has a test suite based on each rule of the
+  IDNA specification, as well as tests that are provided as part of the
+  Unicode Technical Standard 46, `Unicode IDNA Compatibility Processing
+  <https://unicode.org/reports/tr46/>`_.
+
+* **Emoji**. It is an occasional request to support emoji domains in
+  this library. Encoding of symbols like emoji is expressly prohibited by
+  the technical standard IDNA 2008 and emoji domains are broadly phased
+  out across the domain industry due to associated security risks. For
+  now, applications that need to support these non-compliant labels
+  may wish to consider trying the encode/decode operation in this library
+  first, and then falling back to using `encodings.idna`. See `the Github
+  project <https://github.com/kjd/idna/issues/18>`_ for more discussion.
+
+* **Transitional processing**. Unicode 16.0.0 removed transitional
+  processing so the `transitional` argument for the encode() method
+  no longer has any effect and will be removed at a later date.

+# ItsDangerous
+
+... so better sign this
+
+Various helpers to pass data to untrusted environments and to get it
+back safe and sound. Data is cryptographically signed to ensure that a
+token has not been tampered with.
+
+It's possible to customize how data is serialized. Data is compressed as
+needed. A timestamp can be added and verified automatically while
+loading a token.
+
+
+## A Simple Example
+
+Here's how you could generate a token for transmitting a user's id and
+name between web requests.
+
+```python
+from itsdangerous import URLSafeSerializer
+auth_s = URLSafeSerializer("secret key", "auth")
+token = auth_s.dumps({"id": 5, "name": "itsdangerous"})
+
+print(token)
+# eyJpZCI6NSwibmFtZSI6Iml0c2Rhbmdlcm91cyJ9.6YP6T0BaO67XP--9UzTrmurXSmg
+
+data = auth_s.loads(token)
+print(data["name"])
+# itsdangerous
+```

+
+# Jinja
+
+Jinja is a fast, expressive, extensible templating engine. Special
+placeholders in the template allow writing code similar to Python
+syntax. Then the template is passed data to render the final document.
+
+It includes:
+
+-   Template inheritance and inclusion.
+-   Define and import macros within templates.
+-   HTML templates can use autoescaping to prevent XSS from untrusted
+    user input.
+-   A sandboxed environment can safely render untrusted templates.
+-   AsyncIO support for generating templates and calling async
+    functions.
+-   I18N support with Babel.
+-   Templates are compiled to optimized Python code just-in-time and
+    cached, or can be compiled ahead-of-time.
+-   Exceptions point to the correct line in templates to make debugging
+    easier.
+-   Extensible filters, tests, functions, and even syntax.
+
+Jinja's philosophy is that while application logic belongs in Python if
+possible, it shouldn't make the template designer's job difficult by
+restricting functionality too much.
+
+

+    """This class implements a bytecode cache that uses a memcache cache for
+    storing the information.  It does not enforce a specific memcache library
+    (tummy's memcache or cmemcache) but will accept any class that provides
+    the minimal interface required.
+
+    Libraries compatible with this class:
+
+    -   `cachelib <https://github.com/pallets/cachelib>`_
+    -   `python-memcached <https://pypi.org/project/python-memcached/>`_
+
+    (Unfortunately the django cache interface is not compatible because it
+    does not support storing binary data, only text. You can however pass
+    the underlying cache client to the bytecode cache which is available
+    as `django.core.cache.cache._client`.)
+
+    The minimal interface for the client passed to the constructor is this:
+
+    .. class:: MinimalClientInterface
+
+        .. method:: set(key, value[, timeout])
+
+            Stores the bytecode in the cache.  `value` is a string and
+            `timeout` the timeout of the key.  If timeout is not provided
+            a default timeout or no timeout should be assumed, if it's
+            provided it's an integer with the number of seconds the cache
+            item should exist.
+
+        .. method:: get(key)
+
+            Returns the value for the cache key.  If the item does not
+            exist in the cache the return value must be `None`.
+
+    The other arguments to the constructor are the prefix for all keys that
+    is added before the actual cache key and the timeout for the bytecode in
+    the cache system.  We recommend a high (or no) timeout.
+
+    This bytecode cache does not support clearing of used items in the cache.
+    The clear method is a no-operation function.
+
+    .. versionadded:: 2.7
+       Added support for ignoring memcache errors through the
+       `ignore_memcache_errors` parameter.

+    Modifications on environments after the first template was loaded
+    will lead to surprising effects and undefined behavior.
+
+    Here are the possible initialization parameters:
+
+        `block_start_string`
+            The string marking the beginning of a block.  Defaults to ``'{%'``.
+
+        `block_end_string`
+            The string marking the end of a block.  Defaults to ``'%}'``.
+
+        `variable_start_string`
+            The string marking the beginning of a print statement.
+            Defaults to ``'{{'``.
+
+        `variable_end_string`
+            The string marking the end of a print statement.  Defaults to
+            ``'}}'``.
+
+        `comment_start_string`
+            The string marking the beginning of a comment.  Defaults to ``'{#'``.
+
+        `comment_end_string`
+            The string marking the end of a comment.  Defaults to ``'#}'``.
+
+        `line_statement_prefix`
+            If given and a string, this will be used as prefix for line based
+            statements.  See also :ref:`line-statements`.
+
+        `line_comment_prefix`
+            If given and a string, this will be used as prefix for line based
+            comments.  See also :ref:`line-statements`.
+
+            .. versionadded:: 2.2
+
+        `trim_blocks`
+            If this is set to ``True`` the first newline after a block is
+            removed (block, not variable tag!).  Defaults to `False`.
+
+        `lstrip_blocks`
+            If this is set to ``True`` leading spaces and tabs are stripped
+            from the start of a line to a block.  Defaults to `False`.
+
+        `newline_sequence`
+            The sequence that starts a newline.  Must be one of ``'\r'``,
+            ``'\n'`` or ``'\r\n'``.  The default is ``'\n'`` which is a
+            useful default for Linux and OS X systems as well as web
+            applications.
+
+        `keep_trailing_newline`
+            Preserve the trailing newline when rendering templates.
+            The default is ``False``, which causes a single newline,
+            if present, to be stripped from the end of the template.
+
+            .. versionadded:: 2.7
+
+        `extensions`
+            List of Jinja extensions to use.  This can either be import paths
+            as strings or extension classes.  For more information have a
+            look at :ref:`the extensions documentation <jinja-extensions>`.
+
+        `optimized`
+            should the optimizer be enabled?  Default is ``True``.
+
+        `undefined`
+            :class:`Undefined` or a subclass of it that is used to represent
+            undefined values in the template.
+
+        `finalize`
+            A callable that can be used to process the result of a variable
+            expression before it is output.  For example one can convert
+            ``None`` implicitly into an empty string here.
+
+        `autoescape`
+            If set to ``True`` the XML/HTML autoescaping feature is enabled by
+            default.  For more details about autoescaping see
+            :class:`~markupsafe.Markup`.  As of Jinja 2.4 this can also
+            be a callable that is passed the template name and has to
+            return ``True`` or ``False`` depending on autoescape should be
+            enabled by default.
+
+            .. versionchanged:: 2.4
+               `autoescape` can now be a function
+
+        `loader`
+            The template loader for this environment.
+
+        `cache_size`
+            The size of the cache.  Per default this is ``400`` which means
+            that if more than 400 templates are loaded the loader will clean
+            out the least recently used template.  If the cache size is set to
+            ``0`` templates are recompiled all the time, if the cache size is
+            ``-1`` the cache will not be cleaned.
+
+            .. versionchanged:: 2.8
+               The cache size was increased to 400 from a low 50.
+
+        `auto_reload`
+            Some loaders load templates from locations where the template
+            sources may change (ie: file system or database).  If
+            ``auto_reload`` is set to ``True`` (default) every time a template is
+            requested the loader checks if the source changed and if yes, it
+            will reload the template.  For higher performance it's possible to
+            disable that.
+
+        `bytecode_cache`
+            If set to a bytecode cache object, this object will provide a
+            cache for the internal Jinja bytecode so that templates don't
+            have to be parsed if they were not changed.
+
+            See :ref:`bytecode-cache` for more information.
+
+        `enable_async`
+            If set to true this enables async template execution which
+            allows using async functions and generators.

+    unique value.
+
+    For example, a list of ``User`` objects with a ``city`` attribute
+    can be rendered in groups. In this example, ``grouper`` refers to
+    the ``city`` value of the group.
+
+    .. sourcecode:: html+jinja
+
+        <ul>{% for city, items in users|groupby("city") %}
+          <li>{{ city }}
+            <ul>{% for user in items %}
+              <li>{{ user.name }}
+            {% endfor %}</ul>
+          </li>
+        {% endfor %}</ul>
+
+    ``groupby`` yields namedtuples of ``(grouper, list)``, which
+    can be used instead of the tuple unpacking above. ``grouper`` is the
+    value of the attribute, and ``list`` is the items with that value.
+
+    .. sourcecode:: html+jinja
+
+        <ul>{% for group in users|groupby("city") %}
+          <li>{{ group.grouper }}: {{ group.list|join(", ") }}
+        {% endfor %}</ul>
+
+    You can specify a ``default`` value to use if an object in the list
+    does not have the given attribute.
+
+    .. sourcecode:: jinja
+
+        <ul>{% for city, items in users|groupby("city", default="NY") %}
+          <li>{{ city }}: {{ items|map(attribute="name")|join(", ") }}</li>
+        {% endfor %}</ul>
+
+    Like the :func:`~jinja-filters.sort` filter, sorting and grouping is
+    case-insensitive by default. The ``key`` for each group will have
+    the case of the first item in that group of values. For example, if
+    a list of users has cities ``["CA", "NY", "ca"]``, the "CA" group
+    will have two values. This can be disabled by passing
+    ``case_sensitive=True``.
+
+    .. versionchanged:: 3.1
+        Added the ``case_sensitive`` parameter. Sorting and grouping is
+        case-insensitive by default, matching other filters that do
+        comparisons.
+
+    .. versionchanged:: 3.0
+        Added the ``default`` parameter.
+
+    .. versionchanged:: 2.6

+# MarkupSafe
+
+MarkupSafe implements a text object that escapes characters so it is
+safe to use in HTML and XML. Characters that have special meanings are
+replaced so that they display as the actual characters. This mitigates
+injection attacks, meaning untrusted user input can safely be displayed
+on a page.
+
+
+## Examples
+
+```pycon
+>>> from markupsafe import Markup, escape
+
+>>> # escape replaces special characters and wraps in Markup
+>>> escape("<script>alert(document.cookie);</script>")
+Markup('&lt;script&gt;alert(document.cookie);&lt;/script&gt;')
+
+>>> # wrap in Markup to mark text "safe" and prevent escaping
+>>> Markup("<strong>Hello</strong>")
+Markup('<strong>hello</strong>')
+
+>>> escape(Markup("<strong>Hello</strong>"))
+Markup('<strong>hello</strong>')
+
+>>> # Markup is a str subclass
+>>> # methods and operators escape their arguments
+>>> template = Markup("Hello <em>{name}</em>")
+>>> template.format(name='"World"')
+Markup('Hello <em>&#34;World&#34;</em>')
+```

+# OpenAI Python API library
+
+[![PyPI version](https://img.shields.io/pypi/v/openai.svg)](https://pypi.org/project/openai/)
+
+The OpenAI Python library provides convenient access to the OpenAI REST API from any Python 3.7+
+application. The library includes type definitions for all request params and response fields,
+and offers both synchronous and asynchronous clients powered by [httpx](https://github.com/encode/httpx).
+
+It is generated from our [OpenAPI specification](https://github.com/openai/openai-openapi) with [Stainless](https://stainlessapi.com/).
+
+## Documentation
+
+The API documentation can be found [here](https://platform.openai.com/docs).
+
+## Installation
+
+> [!IMPORTANT]
+> The SDK was rewritten in v1, which was released November 6th 2023. See the [v1 migration guide](https://github.com/openai/openai-python/discussions/742), which includes scripts to automatically update your code.
+
+```sh
+pip install openai
+```
+
+## Usage
+
+The full API of this library can be found in [api.md](https://www.github.com/openai/openai-python/blob/main/api.md).
+
+```python
+from openai import OpenAI
+
+client = OpenAI(
+    # defaults to os.environ.get("OPENAI_API_KEY")
+    api_key="My API Key",
+)
+
+chat_completion = client.chat.completions.create(
+    messages=[
+        {
+            "role": "user",
+            "content": "Say this is a test",
+        }
+    ],
+    model="gpt-3.5-turbo",
+)
+```
+
+While you can provide an `api_key` keyword argument,
+we recommend using [python-dotenv](https://pypi.org/project/python-dotenv/)
+to add `OPENAI_API_KEY="My API Key"` to your `.env` file
+so that your API Key is not stored in source control.

+Simply import `AsyncOpenAI` instead of `OpenAI` and use `await` with each API call:
+
+```python
+import asyncio
+from openai import AsyncOpenAI
+
+client = AsyncOpenAI(
+    # defaults to os.environ.get("OPENAI_API_KEY")
+    api_key="My API Key",
+)
+
+
+async def main() -> None:
+    chat_completion = await client.chat.completions.create(
+        messages=[
+            {
+                "role": "user",
+                "content": "Say this is a test",
+            }
+        ],
+        model="gpt-3.5-turbo",
+    )
+
+
+asyncio.run(main())
+```
+
+Functionality between the synchronous and asynchronous clients is otherwise identical.
+
+## Streaming Responses
+
+We provide support for streaming responses using Server Side Events (SSE).
+
+```python
+from openai import OpenAI
+
+client = OpenAI()
+
+stream = client.chat.completions.create(
+    model="gpt-4",
+    messages=[{"role": "user", "content": "Say this is a test"}],
+    stream=True,
+)
+for part in stream:
+    print(part.choices[0].delta.content or "")
+```
+
+The async client uses the exact same interface.
+
+```python
+from openai import AsyncOpenAI
+
+client = AsyncOpenAI()
+
+stream = await client.chat.completions.create(
+    prompt="Say this is a test",
+    messages=[{"role": "user", "content": "Say this is a test"}],
+    stream=True,
+)
+async for part in stream:
+    print(part.choices[0].delta.content or "")
+```
+
+## Module-level client
+
+> [!IMPORTANT]
+> We highly recommend instantiating client instances instead of relying on the global client.
+
+We also expose a global client instance that is accessible in a similar fashion to versions prior to v1.
+
+```py
+import openai
+
+# optional; defaults to `os.environ['OPENAI_API_KEY']`
+openai.api_key = '...'
+
+# all client options can be configured just like the `OpenAI` instantiation counterpart
+openai.base_url = "https://..."
+openai.default_headers = {"x-foo": "true"}
+
+completion = openai.chat.completions.create(
+    model="gpt-4",
+    messages=[
+        {
+            "role": "user",
+            "content": "How do I output all files in a directory using Python?",
+        },
+    ],
+)
+print(completion.choices[0].message.content)
+```
+
+The API is the exact same as the standard client instance based API.
+
+This is intended to be used within REPLs or notebooks for faster iteration, **not** in application code.
+
+We recommend that you always instantiate a client (e.g., with `client = OpenAI()`) in application code because:
+
+- It can be difficult to reason about where client options are configured
+- It's not possible to change certain client options without potentially causing race conditions
+- It's harder to mock for testing purposes
+- It's not possible to control cleanup of network connections
+
+## Using types
+
+Nested request parameters are [TypedDicts](https://docs.python.org/3/library/typing.html#typing.TypedDict). Responses are [Pydantic models](https://docs.pydantic.dev), which provide helper methods for things like serializing back into JSON ([v1](https://docs.pydantic.dev/1.10/usage/models/), [v2](https://docs.pydantic.dev/latest/usage/serialization/)). To get a dictionary, call `model.model_dump()`.
+
+Typed requests and responses provide autocomplete and documentation within your editor. If you would like to see type errors in VS Code to help catch bugs earlier, set `python.analysis.typeCheckingMode` to `basic`.
+
+## Pagination
+
+List methods in the OpenAI API are paginated.
+
+This library provides auto-paginating iterators with each list response, so you do not have to request successive pages manually:
+
+```python
+import openai
+
+client = OpenAI()
+
+all_jobs = []
+# Automatically fetches more pages as needed.
+for job in client.fine_tuning.jobs.list(
+    limit=20,
+):
+    # Do something with job here
+    all_jobs.append(job)
+print(all_jobs)
+```
+
+Or, asynchronously:
+
+```python
+import asyncio
+import openai
+
+client = AsyncOpenAI()
+
+
+async def main() -> None:
+    all_jobs = []
+    # Iterate through items across all pages, issuing requests as needed.
+    async for job in client.fine_tuning.jobs.list(
+        limit=20,
+    ):
+        all_jobs.append(job)
+    print(all_jobs)
+
+
+asyncio.run(main())
+```
+
+Alternatively, you can use the `.has_next_page()`, `.next_page_info()`, or `.get_next_page()` methods for more granular control working with pages:
+
+```python
+first_page = await client.fine_tuning.jobs.list(
+    limit=20,
+)
+if first_page.has_next_page():
+    print(f"will fetch next page using these details: {first_page.next_page_info()}")
+    next_page = await first_page.get_next_page()
+    print(f"number of items we just fetched: {len(next_page.data)}")
+
+# Remove `await` for non-async usage.
+```
+
+Or just work directly with the returned data:
+
+```python
+first_page = await client.fine_tuning.jobs.list(
+    limit=20,
+)
+
+print(f"next page cursor: {first_page.after}")  # => "next page cursor: ..."
+for job in first_page.data:
+    print(job.id)
+
+# Remove `await` for non-async usage.
+```
+
+## Nested params
+
+Nested parameters are dictionaries, typed using `TypedDict`, for example:
+
+```python
+from openai import OpenAI
+
+client = OpenAI()
+
+completion = client.chat.completions.create(
+    messages=[
+        {
+            "role": "user",
+            "content": "Can you generate an example json object describing a fruit?",
+        }
+    ],
+    model="gpt-3.5-turbo",
+    response_format={"type": "json_object"},
+)
+```
+
+## File Uploads
+
+Request parameters that correspond to file uploads can be passed as `bytes`, a [`PathLike`](https://docs.python.org/3/library/os.html#os.PathLike) instance or a tuple of `(filename, contents, media type)`.
+
+```python
+from pathlib import Path
+from openai import OpenAI
+
+client = OpenAI()
+
+client.files.create(
+    file=Path("input.jsonl"),
+    purpose="fine-tune",
+)
+```
+
+The async client uses the exact same interface. If you pass a [`PathLike`](https://docs.python.org/3/library/os.html#os.PathLike) instance, the file contents will be read asynchronously automatically.
+
+## Handling errors
+
+When the library is unable to connect to the API (for example, due to network connection problems or a timeout), a subclass of `openai.APIConnectionError` is raised.
+
+When the API returns a non-success status code (that is, 4xx or 5xx
+response), a subclass of `openai.APIStatusError` is raised, containing `status_code` and `response` properties.
+
+All errors inherit from `openai.APIError`.
+
+```python
+import openai
+from openai import OpenAI
+
+client = OpenAI()
+
+try:
+    client.fine_tunes.create(
+        training_file="file-XGinujblHPwGLSztz8cPS8XY",
+    )
+except openai.APIConnectionError as e:
+    print("The server could not be reached")
+    print(e.__cause__)  # an underlying Exception, likely raised within httpx.
+except openai.RateLimitError as e:
+    print("A 429 status code was received; we should back off a bit.")
+except openai.APIStatusError as e:
+    print("Another non-200-range status code was received")
+    print(e.status_code)
+    print(e.response)
+```
+
+Error codes are as followed:
+
+| Status Code | Error Type                 |
+| ----------- | -------------------------- |
+| 400         | `BadRequestError`          |
+| 401         | `AuthenticationError`      |
+| 403         | `PermissionDeniedError`    |
+| 404         | `NotFoundError`            |
+| 422         | `UnprocessableEntityError` |
+| 429         | `RateLimitError`           |
+| >=500       | `InternalServerError`      |
+| N/A         | `APIConnectionError`       |
+
+### Retries
+
+Certain errors are automatically retried 2 times by default, with a short exponential backoff.
+Connection errors (for example, due to a network connectivity problem), 408 Request Timeout, 409 Conflict,
+429 Rate Limit, and >=500 Internal errors are all retried by default.
+
+You can use the `max_retries` option to configure or disable retry settings:
+
+```python
+from openai import OpenAI
+
+# Configure the default for all requests:
+client = OpenAI(
+    # default is 2
+    max_retries=0,
+)
+
+# Or, configure per-request:
+client.with_options(max_retries=5).chat.completions.create(
+    messages=[
+        {
+            "role": "user",
+            "content": "How can I get the name of the current day in Node.js?",
+        }
+    ],
+    model="gpt-3.5-turbo",
+)
+```
+
+### Timeouts
+
+By default requests time out after 10 minutes. You can configure this with a `timeout` option,
+which accepts a float or an [`httpx.Timeout`](https://www.python-httpx.org/advanced/#fine-tuning-the-configuration) object:
+
+```python
+from openai import OpenAI
+
+# Configure the default for all requests:
+client = OpenAI(
+    # default is 60s
+    timeout=20.0,
+)
+
+# More granular control:
+client = OpenAI(
+    timeout=httpx.Timeout(60.0, read=5.0, write=10.0, connect=2.0),
+)
+
+# Override per-request:
+client.with_options(timeout=5 * 1000).chat.completions.create(
+    messages=[
+        {
+            "role": "user",
+            "content": "How can I list all files in a directory using Python?",
+        }
+    ],
+    model="gpt-3.5-turbo",
+)
+```
+
+On timeout, an `APITimeoutError` is thrown.
+
+Note that requests that time out are [retried twice by default](#retries).
+
+## Advanced
+
+### Logging
+
+We use the standard library [`logging`](https://docs.python.org/3/library/logging.html) module.
+
+You can enable logging by setting the environment variable `OPENAI_LOG` to `debug`.
+
+```shell
+$ export OPENAI_LOG=debug
+```
+
+### How to tell whether `None` means `null` or missing
+
+In an API response, a field may be explicitly `null`, or missing entirely; in either case, its value is `None` in this library. You can differentiate the two cases with `.model_fields_set`:
+
+```py
+if response.my_field is None:
+  if 'my_field' not in response.model_fields_set:
+    print('Got json like {}, without a "my_field" key present at all.')
+  else:
+    print('Got json like {"my_field": null}.')
+```
+
+### Accessing raw response data (e.g. headers)
+
+The "raw" Response object can be accessed by prefixing `.with_raw_response.` to any HTTP method call.
+
+```py
+from openai import OpenAI
+
+client = OpenAI()
+response = client.chat.completions.with_raw_response.create(
+    messages=[{
+        "role": "user",
+        "content": "Say this is a test",
+    }],
+    model="gpt-3.5-turbo",
+)
+print(response.headers.get('X-My-Header'))
+
+completion = response.parse()  # get the object that `chat.completions.create()` would have returned
+print(completion)
+```
+
+These methods return an [`APIResponse`](https://github.com/openai/openai-python/tree/main/src/openai/_response.py) object.
+
+### Configuring the HTTP client
+
+You can directly override the [httpx client](https://www.python-httpx.org/api/#client) to customize it for your use case, including:
+
+- Support for proxies
+- Custom transports
+- Additional [advanced](https://www.python-httpx.org/advanced/#client-instances) functionality
+
+```python
+import httpx
+from openai import OpenAI
+
+client = OpenAI(
+    # Or use the `OPENAI_BASE_URL` env var
+    base_url="http://my.test.server.example.com:8083",
+    http_client=httpx.Client(
+        proxies="http://my.test.proxy.example.com",
+        transport=httpx.HTTPTransport(local_address="0.0.0.0"),
+    ),
+)
+```
+
+### Managing HTTP resources
+
+By default the library closes underlying HTTP connections whenever the client is [garbage collected](https://docs.python.org/3/reference/datamodel.html#object.__del__). You can manually close the client using the `.close()` method if desired, or with a context manager that closes when exiting.
+
+## Microsoft Azure OpenAI
+
+To use this library with [Azure OpenAI](https://learn.microsoft.com/en-us/azure/ai-services/openai/overview), use the `AzureOpenAI`
+class instead of the `OpenAI` class.
+
+> [!IMPORTANT]
+> The Azure API shape differs from the core API shape which means that the static types for responses / params
+> won't always be correct.
+
+```py
+from openai import AzureOpenAI
+
+# gets the API Key from environment variable AZURE_OPENAI_API_KEY
+client = AzureOpenAI(
+    # https://learn.microsoft.com/en-us/azure/ai-services/openai/reference#rest-api-versioning
+    api_version="2023-07-01-preview"
+    # https://learn.microsoft.com/en-us/azure/cognitive-services/openai/how-to/create-resource?pivots=web-portal#create-a-resource
+    azure_endpoint="https://example-endpoint.openai.azure.com",
+)
+
+completion = client.chat.completions.create(
+    model="deployment-name",  # e.g. gpt-35-instant
+    messages=[
+        {
+            "role": "user",
+            "content": "How do I output all files in a directory using Python?",
+        },
+    ],
+)
+print(completion.model_dump_json(indent=2))
+```
+
+In addition to the options provided in the base `OpenAI` client, the following options are provided:
+
+- `azure_endpoint` (or the `AZURE_OPENAI_ENDPOINT` environment variable)
+- `azure_deployment`
+- `api_version` (or the `OPENAI_API_VERSION` environment variable)
+- `azure_ad_token` (or the `AZURE_OPENAI_AD_TOKEN` environment variable)
+- `azure_ad_token_provider`
+
+An example of using the client with Azure Active Directory can be found [here](https://github.com/openai/openai-python/blob/main/examples/azure_ad.py).
+
+## Versioning
+
+This package generally follows [SemVer](https://semver.org/spec/v2.0.0.html) conventions, though certain backwards-incompatible changes may be released as minor versions:
+
+1. Changes that only affect static types, without breaking runtime behavior.
+2. Changes to library internals which are technically public but not intended or documented for external use. _(Please open a GitHub issue to let us know if you are relying on such internals)_.
+3. Changes that we do not expect to impact the vast majority of users in practice.
+
+We take backwards-compatibility seriously and work hard to ensure you can rely on a smooth upgrade experience.
+
+We are keen for your feedback; please open an [issue](https://www.github.com/openai/openai-python/issues) with questions, bugs, or suggestions.
+
+## Requirements
+
+Python 3.7 or higher.

+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this

+          function_call: Deprecated in favor of `tool_choice`.
+
+              Controls which (if any) function is called by the model. `none` means the model
+              will not call a function and instead generates a message. `auto` means the model
+              can pick between generating a message or calling a function. Specifying a
+              particular function via `{"name": "my_function"}` forces the model to call that
+              function.
+
+              `none` is the default when no functions are present. `auto`` is the default if
+              functions are present.
+
+          functions: Deprecated in favor of `tools`.
+
+              A list of functions the model may generate JSON inputs for.
+
+          logit_bias: Modify the likelihood of specified tokens appearing in the completion.
+
+              Accepts a JSON object that maps tokens (specified by their token ID in the
+              tokenizer) to an associated bias value from -100 to 100. Mathematically, the
+              bias is added to the logits generated by the model prior to sampling. The exact
+              effect will vary per model, but values between -1 and 1 should decrease or
+              increase likelihood of selection; values like -100 or 100 should result in a ban
+              or exclusive selection of the relevant token.
+
+          max_tokens: The maximum number of [tokens](/tokenizer) to generate in the chat completion.
+
+              The total length of input tokens and generated tokens is limited by the model's
+              context length.
+              [Example Python code](https://cookbook.openai.com/examples/how_to_count_tokens_with_tiktoken)
+              for counting tokens.
+
+          n: How many chat completion choices to generate for each input message.
+
+          presence_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on
+              whether they appear in the text so far, increasing the model's likelihood to
+              talk about new topics.
+
+              [See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/gpt/parameter-details)
+
+          response_format: An object specifying the format that the model must output.
+
+              Setting to `{ "type": "json_object" }` enables JSON mode, which guarantees the
+              message the model generates is valid JSON.
+
+              **Important:** when using JSON mode, you **must** also instruct the model to
+              produce JSON yourself via a system or user message. Without this, the model may
+              generate an unending stream of whitespace until the generation reaches the token
+              limit, resulting in increased latency and appearance of a "stuck" request. Also
+              note that the message content may be partially cut off if
+              `finish_reason="length"`, which indicates the generation exceeded `max_tokens`
+              or the conversation exceeded the max context length.
+
+          seed: This feature is in Beta. If specified, our system will make a best effort to
+              sample deterministically, such that repeated requests with the same `seed` and
+              parameters should return the same result. Determinism is not guaranteed, and you
+              should refer to the `system_fingerprint` response parameter to monitor changes
+              in the backend.
+
+          stop: Up to 4 sequences where the API will stop generating further tokens.
+
+          stream: If set, partial message deltas will be sent, like in ChatGPT. Tokens will be
+              sent as data-only
+              [server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events#Event_stream_format)
+              as they become available, with the stream terminated by a `data: [DONE]`
+              message.
+              [Example Python code](https://cookbook.openai.com/examples/how_to_stream_completions).
+
+          temperature: What sampling temperature to use, between 0 and 2. Higher values like 0.8 will
+              make the output more random, while lower values like 0.2 will make it more
+              focused and deterministic.
+
+              We generally recommend altering this or `top_p` but not both.
+
+          tool_choice: Controls which (if any) function is called by the model. `none` means the model
+              will not call a function and instead generates a message. `auto` means the model
+              can pick between generating a message or calling a function. Specifying a
+              particular function via
+              `{"type: "function", "function": {"name": "my_function"}}` forces the model to
+              call that function.
+
+              `none` is the default when no functions are present. `auto` is the default if
+              functions are present.
+
+          tools: A list of tools the model may call. Currently, only functions are supported as a
+              tool. Use this to provide a list of functions the model may generate JSON inputs
+              for.
+
+          top_p: An alternative to sampling with temperature, called nucleus sampling, where the
+              model considers the results of the tokens with top_p probability mass. So 0.1
+              means only the tokens comprising the top 10% probability mass are considered.
+
+              We generally recommend altering this or `temperature` but not both.
+
+          user: A unique identifier representing your end-user, which can help OpenAI to monitor
+              and detect abuse.

+          response_format: An object specifying the format that the model must output.
+
+              Setting to `{ "type": "json_object" }` enables JSON mode, which guarantees the
+              message the model generates is valid JSON.
+
+              **Important:** when using JSON mode, you **must** also instruct the model to
+              produce JSON yourself via a system or user message. Without this, the model may
+              generate an unending stream of whitespace until the generation reaches the token
+              limit, resulting in increased latency and appearance of a "stuck" request. Also
+              note that the message content may be partially cut off if
+              `finish_reason="length"`, which indicates the generation exceeded `max_tokens`
+              or the conversation exceeded the max context length.
+
+          seed: This feature is in Beta. If specified, our system will make a best effort to
+              sample deterministically, such that repeated requests with the same `seed` and
+              parameters should return the same result. Determinism is not guaranteed, and you
+              should refer to the `system_fingerprint` response parameter to monitor changes
+              in the backend.
+
+          stop: Up to 4 sequences where the API will stop generating further tokens.
+
+          temperature: What sampling temperature to use, between 0 and 2. Higher values like 0.8 will
+              make the output more random, while lower values like 0.2 will make it more
+              focused and deterministic.
+
+              We generally recommend altering this or `top_p` but not both.
+
+          tool_choice: Controls which (if any) function is called by the model. `none` means the model
+              will not call a function and instead generates a message. `auto` means the model
+              can pick between generating a message or calling a function. Specifying a
+              particular function via
+              `{"type: "function", "function": {"name": "my_function"}}` forces the model to
+              call that function.
+
+              `none` is the default when no functions are present. `auto` is the default if
+              functions are present.
+
+          tools: A list of tools the model may call. Currently, only functions are supported as a

+              for.
+
+          top_p: An alternative to sampling with temperature, called nucleus sampling, where the
+              model considers the results of the tokens with top_p probability mass. So 0.1
+              means only the tokens comprising the top 10% probability mass are considered.

+
+              **Important:** when using JSON mode, you **must** also instruct the model to
+              produce JSON yourself via a system or user message. Without this, the model may
+              generate an unending stream of whitespace until the generation reaches the token

+              [model endpoint compatibility](https://platform.openai.com/docs/models/model-endpoint-compatibility)
+              table for details on which models work with the Chat API.
+
+          stream: If set, partial message deltas will be sent, like in ChatGPT. Tokens will be
+              sent as data-only
+              [server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events#Event_stream_format)
+              as they become available, with the stream terminated by a `data: [DONE]`
+              message.
+              [Example Python code](https://cookbook.openai.com/examples/how_to_stream_completions).
+
+          frequency_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on their
+              existing frequency in the text so far, decreasing the model's likelihood to
+              repeat the same line verbatim.

+              [See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/gpt/parameter-details)
+
+          function_call: Deprecated in favor of `tool_choice`.
+
+              Controls which (if any) function is called by the model. `none` means the model
+              will not call a function and instead generates a message. `auto` means the model
+              can pick between generating a message or calling a function. Specifying a
+              particular function via `{"name": "my_function"}` forces the model to call that
+              function.
+
+              `none` is the default when no functions are present. `auto`` is the default if
+              functions are present.
+
+          functions: Deprecated in favor of `tools`.
+
+              A list of functions the model may generate JSON inputs for.
+
+          logit_bias: Modify the likelihood of specified tokens appearing in the completion.
+
+              Accepts a JSON object that maps tokens (specified by their token ID in the
+              tokenizer) to an associated bias value from -100 to 100. Mathematically, the
+              bias is added to the logits generated by the model prior to sampling. The exact
+              effect will vary per model, but values between -1 and 1 should decrease or
+              increase likelihood of selection; values like -100 or 100 should result in a ban
+              or exclusive selection of the relevant token.
+
+          max_tokens: The maximum number of [tokens](/tokenizer) to generate in the chat completion.
+
+              The total length of input tokens and generated tokens is limited by the model's
+              context length.
+              [Example Python code](https://cookbook.openai.com/examples/how_to_count_tokens_with_tiktoken)
+              for counting tokens.
+
+          n: How many chat completion choices to generate for each input message.
+
+          presence_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on
+              whether they appear in the text so far, increasing the model's likelihood to
+              talk about new topics.
+
+              [See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/gpt/parameter-details)
+
+          response_format: An object specifying the format that the model must output.
+
+              Setting to `{ "type": "json_object" }` enables JSON mode, which guarantees the
+              message the model generates is valid JSON.
+
+              **Important:** when using JSON mode, you **must** also instruct the model to
+              produce JSON yourself via a system or user message. Without this, the model may
+              generate an unending stream of whitespace until the generation reaches the token
+              limit, resulting in increased latency and appearance of a "stuck" request. Also
+              note that the message content may be partially cut off if
+              `finish_reason="length"`, which indicates the generation exceeded `max_tokens`
+              or the conversation exceeded the max context length.
+
+          seed: This feature is in Beta. If specified, our system will make a best effort to
+              sample deterministically, such that repeated requests with the same `seed` and
+              parameters should return the same result. Determinism is not guaranteed, and you
+              should refer to the `system_fingerprint` response parameter to monitor changes
+              in the backend.
+
+          stop: Up to 4 sequences where the API will stop generating further tokens.
+
+          temperature: What sampling temperature to use, between 0 and 2. Higher values like 0.8 will
+              make the output more random, while lower values like 0.2 will make it more
+              focused and deterministic.
+
+              We generally recommend altering this or `top_p` but not both.
+
+          tool_choice: Controls which (if any) function is called by the model. `none` means the model
+              will not call a function and instead generates a message. `auto` means the model
+              can pick between generating a message or calling a function. Specifying a
+              particular function via
+              `{"type: "function", "function": {"name": "my_function"}}` forces the model to
+              call that function.
+
+              `none` is the default when no functions are present. `auto` is the default if
+              functions are present.
+
+          tools: A list of tools the model may call. Currently, only functions are supported as a
+              tool. Use this to provide a list of functions the model may generate JSON inputs
+              for.
+
+          top_p: An alternative to sampling with temperature, called nucleus sampling, where the
+              model considers the results of the tokens with top_p probability mass. So 0.1
+              means only the tokens comprising the top 10% probability mass are considered.
+
+              We generally recommend altering this or `temperature` but not both.
+
+          user: A unique identifier representing your end-user, which can help OpenAI to monitor
+              and detect abuse.
+              [Learn more](https://platform.openai.com/docs/guides/safety-best-practices/end-user-ids).

+        Creates a completion for the provided prompt and parameters.
+
+        Args:
+          model: ID of the model to use. You can use the
+              [List models](https://platform.openai.com/docs/api-reference/models/list) API to
+              see all of your available models, or see our
+              [Model overview](https://platform.openai.com/docs/models/overview) for
+              descriptions of them.
+
+          prompt: The prompt(s) to generate completions for, encoded as a string, array of
+              strings, array of tokens, or array of token arrays.
+
+              Note that <|endoftext|> is the document separator that the model sees during
+              training, so if a prompt is not specified the model will generate as if from the
+              beginning of a new document.
+
+          best_of: Generates `best_of` completions server-side and returns the "best" (the one with
+              the highest log probability per token). Results cannot be streamed.
+
+              When used with `n`, `best_of` controls the number of candidate completions and
+              `n` specifies how many to return – `best_of` must be greater than `n`.
+
+              **Note:** Because this parameter generates many completions, it can quickly
+              consume your token quota. Use carefully and ensure that you have reasonable
+              settings for `max_tokens` and `stop`.
+
+          echo: Echo back the prompt in addition to the completion
+
+          frequency_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on their
+              existing frequency in the text so far, decreasing the model's likelihood to
+              repeat the same line verbatim.
+
+              [See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/gpt/parameter-details)
+
+          logit_bias: Modify the likelihood of specified tokens appearing in the completion.
+
+              Accepts a JSON object that maps tokens (specified by their token ID in the GPT
+              tokenizer) to an associated bias value from -100 to 100. You can use this
+              [tokenizer tool](/tokenizer?view=bpe) (which works for both GPT-2 and GPT-3) to
+              convert text to token IDs. Mathematically, the bias is added to the logits
+              generated by the model prior to sampling. The exact effect will vary per model,
+              but values between -1 and 1 should decrease or increase likelihood of selection;
+              values like -100 or 100 should result in a ban or exclusive selection of the
+              relevant token.
+
+              As an example, you can pass `{"50256": -100}` to prevent the <|endoftext|> token
+              from being generated.
+
+          logprobs: Include the log probabilities on the `logprobs` most likely tokens, as well the
+              chosen tokens. For example, if `logprobs` is 5, the API will return a list of
+              the 5 most likely tokens. The API will always return the `logprob` of the
+              sampled token, so there may be up to `logprobs+1` elements in the response.
+
+              The maximum value for `logprobs` is 5.
+
+          max_tokens: The maximum number of [tokens](/tokenizer) to generate in the completion.
+
+              The token count of your prompt plus `max_tokens` cannot exceed the model's
+              context length.
+              [Example Python code](https://cookbook.openai.com/examples/how_to_count_tokens_with_tiktoken)
+              for counting tokens.
+
+          n: How many completions to generate for each prompt.
+
+              **Note:** Because this parameter generates many completions, it can quickly
+              consume your token quota. Use carefully and ensure that you have reasonable
+              settings for `max_tokens` and `stop`.
+
+          presence_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on
+              whether they appear in the text so far, increasing the model's likelihood to
+              talk about new topics.
+
+              [See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/gpt/parameter-details)
+
+          seed: If specified, our system will make a best effort to sample deterministically,
+              such that repeated requests with the same `seed` and parameters should return
+              the same result.
+
+              Determinism is not guaranteed, and you should refer to the `system_fingerprint`
+              response parameter to monitor changes in the backend.
+
+          stop: Up to 4 sequences where the API will stop generating further tokens. The
+              returned text will not contain the stop sequence.

+              strings, array of tokens, or array of token arrays.
+
+              Note that <|endoftext|> is the document separator that the model sees during

+
+          best_of: Generates `best_of` completions server-side and returns the "best" (the one with
+              the highest log probability per token). Results cannot be streamed.
+
+              When used with `n`, `best_of` controls the number of candidate completions and
+              `n` specifies how many to return – `best_of` must be greater than `n`.
+
+              **Note:** Because this parameter generates many completions, it can quickly

+              [tokenizer tool](/tokenizer?view=bpe) (which works for both GPT-2 and GPT-3) to
+              convert text to token IDs. Mathematically, the bias is added to the logits
+              generated by the model prior to sampling. The exact effect will vary per model,
+              but values between -1 and 1 should decrease or increase likelihood of selection;
+              values like -100 or 100 should result in a ban or exclusive selection of the
+              relevant token.
+
+              As an example, you can pass `{"50256": -100}` to prevent the <|endoftext|> token
+              from being generated.
+
+          logprobs: Include the log probabilities on the `logprobs` most likely tokens, as well the
+              chosen tokens. For example, if `logprobs` is 5, the API will return a list of
+              the 5 most likely tokens. The API will always return the `logprob` of the
+              sampled token, so there may be up to `logprobs+1` elements in the response.
+
+              The maximum value for `logprobs` is 5.

+          max_tokens: The maximum number of [tokens](/tokenizer) to generate in the completion.
+
+              The token count of your prompt plus `max_tokens` cannot exceed the model's
+              context length.

+
+              Determinism is not guaranteed, and you should refer to the `system_fingerprint`

+
+        Args:
+          model: ID of the model to use. You can use the
+              [List models](https://platform.openai.com/docs/api-reference/models/list) API to
+              see all of your available models, or see our
+              [Model overview](https://platform.openai.com/docs/models/overview) for
+              descriptions of them.
+
+          prompt: The prompt(s) to generate completions for, encoded as a string, array of
+              strings, array of tokens, or array of token arrays.
+
+              Note that <|endoftext|> is the document separator that the model sees during
+              training, so if a prompt is not specified the model will generate as if from the
+              beginning of a new document.
+
+          best_of: Generates `best_of` completions server-side and returns the "best" (the one with
+              the highest log probability per token). Results cannot be streamed.
+
+              When used with `n`, `best_of` controls the number of candidate completions and
+              `n` specifies how many to return – `best_of` must be greater than `n`.
+
+              **Note:** Because this parameter generates many completions, it can quickly
+              consume your token quota. Use carefully and ensure that you have reasonable
+              settings for `max_tokens` and `stop`.
+
+          echo: Echo back the prompt in addition to the completion
+
+          frequency_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on their
+              existing frequency in the text so far, decreasing the model's likelihood to
+              repeat the same line verbatim.
+
+              [See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/gpt/parameter-details)
+
+          logit_bias: Modify the likelihood of specified tokens appearing in the completion.
+
+              Accepts a JSON object that maps tokens (specified by their token ID in the GPT
+              tokenizer) to an associated bias value from -100 to 100. You can use this
+              [tokenizer tool](/tokenizer?view=bpe) (which works for both GPT-2 and GPT-3) to
+              convert text to token IDs. Mathematically, the bias is added to the logits
+              generated by the model prior to sampling. The exact effect will vary per model,
+              but values between -1 and 1 should decrease or increase likelihood of selection;
+              values like -100 or 100 should result in a ban or exclusive selection of the
+              relevant token.
+
+              As an example, you can pass `{"50256": -100}` to prevent the <|endoftext|> token
+              from being generated.
+
+          logprobs: Include the log probabilities on the `logprobs` most likely tokens, as well the
+              chosen tokens. For example, if `logprobs` is 5, the API will return a list of
+              the 5 most likely tokens. The API will always return the `logprob` of the
+              sampled token, so there may be up to `logprobs+1` elements in the response.
+
+              The maximum value for `logprobs` is 5.
+
+          max_tokens: The maximum number of [tokens](/tokenizer) to generate in the completion.
+
+              The token count of your prompt plus `max_tokens` cannot exceed the model's
+              context length.
+              [Example Python code](https://cookbook.openai.com/examples/how_to_count_tokens_with_tiktoken)
+              for counting tokens.
+
+          n: How many completions to generate for each prompt.
+
+              **Note:** Because this parameter generates many completions, it can quickly
+              consume your token quota. Use carefully and ensure that you have reasonable
+              settings for `max_tokens` and `stop`.
+
+          presence_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on
+              whether they appear in the text so far, increasing the model's likelihood to
+              talk about new topics.
+
+              [See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/gpt/parameter-details)
+
+          seed: If specified, our system will make a best effort to sample deterministically,
+              such that repeated requests with the same `seed` and parameters should return
+              the same result.
+
+              Determinism is not guaranteed, and you should refer to the `system_fingerprint`
+              response parameter to monitor changes in the backend.
+
+          stop: Up to 4 sequences where the API will stop generating further tokens. The
+              returned text will not contain the stop sequence.
+
+          stream: Whether to stream back partial progress. If set, tokens will be sent as
+              data-only
+              [server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events#Event_stream_format)

+              message.
+              [Example Python code](https://cookbook.openai.com/examples/how_to_stream_completions).
+
+          suffix: The suffix that comes after a completion of inserted text.
+
+          temperature: What sampling temperature to use, between 0 and 2. Higher values like 0.8 will
+              make the output more random, while lower values like 0.2 will make it more
+              focused and deterministic.
+
+              We generally recommend altering this or `top_p` but not both.
+
+          top_p: An alternative to sampling with temperature, called nucleus sampling, where the
+              model considers the results of the tokens with top_p probability mass. So 0.1
+              means only the tokens comprising the top 10% probability mass are considered.
+
+              We generally recommend altering this or `temperature` but not both.
+
+          user: A unique identifier representing your end-user, which can help OpenAI to monitor
+              and detect abuse.

+        Creates a completion for the provided prompt and parameters.
+
+        Args:
+          model: ID of the model to use. You can use the
+              [List models](https://platform.openai.com/docs/api-reference/models/list) API to
+              see all of your available models, or see our
+              [Model overview](https://platform.openai.com/docs/models/overview) for
+              descriptions of them.
+
+          prompt: The prompt(s) to generate completions for, encoded as a string, array of
+              strings, array of tokens, or array of token arrays.
+
+              Note that <|endoftext|> is the document separator that the model sees during
+              training, so if a prompt is not specified the model will generate as if from the
+              beginning of a new document.
+
+          stream: Whether to stream back partial progress. If set, tokens will be sent as
+              data-only
+              [server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events#Event_stream_format)
+              as they become available, with the stream terminated by a `data: [DONE]`
+              message.
+              [Example Python code](https://cookbook.openai.com/examples/how_to_stream_completions).
+
+          best_of: Generates `best_of` completions server-side and returns the "best" (the one with
+              the highest log probability per token). Results cannot be streamed.
+
+              When used with `n`, `best_of` controls the number of candidate completions and
+              `n` specifies how many to return – `best_of` must be greater than `n`.
+
+              **Note:** Because this parameter generates many completions, it can quickly
+              consume your token quota. Use carefully and ensure that you have reasonable
+              settings for `max_tokens` and `stop`.
+
+          echo: Echo back the prompt in addition to the completion
+
+          frequency_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on their
+              existing frequency in the text so far, decreasing the model's likelihood to
+              repeat the same line verbatim.
+
+              [See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/gpt/parameter-details)
+
+          logit_bias: Modify the likelihood of specified tokens appearing in the completion.
+
+              Accepts a JSON object that maps tokens (specified by their token ID in the GPT
+              tokenizer) to an associated bias value from -100 to 100. You can use this
+              [tokenizer tool](/tokenizer?view=bpe) (which works for both GPT-2 and GPT-3) to
+              convert text to token IDs. Mathematically, the bias is added to the logits
+              generated by the model prior to sampling. The exact effect will vary per model,
+              but values between -1 and 1 should decrease or increase likelihood of selection;
+              values like -100 or 100 should result in a ban or exclusive selection of the
+              relevant token.
+
+              As an example, you can pass `{"50256": -100}` to prevent the <|endoftext|> token
+              from being generated.
+
+          logprobs: Include the log probabilities on the `logprobs` most likely tokens, as well the
+              chosen tokens. For example, if `logprobs` is 5, the API will return a list of
+              the 5 most likely tokens. The API will always return the `logprob` of the
+              sampled token, so there may be up to `logprobs+1` elements in the response.
+
+              The maximum value for `logprobs` is 5.
+
+          max_tokens: The maximum number of [tokens](/tokenizer) to generate in the completion.
+
+              The token count of your prompt plus `max_tokens` cannot exceed the model's
+              context length.
+              [Example Python code](https://cookbook.openai.com/examples/how_to_count_tokens_with_tiktoken)
+              for counting tokens.
+
+          n: How many completions to generate for each prompt.
+
+              **Note:** Because this parameter generates many completions, it can quickly
+              consume your token quota. Use carefully and ensure that you have reasonable
+              settings for `max_tokens` and `stop`.
+
+          presence_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on
+              whether they appear in the text so far, increasing the model's likelihood to
+              talk about new topics.
+
+              [See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/gpt/parameter-details)

+
+        Args:
+          training_file: The ID of an uploaded file that contains training data.
+
+              See [upload file](https://platform.openai.com/docs/api-reference/files/upload)
+              for how to upload a file.
+
+              Your dataset must be formatted as a JSONL file, where each training example is a
+              JSON object with the keys "prompt" and "completion". Additionally, you must
+              upload your file with the purpose `fine-tune`.
+
+              See the
+              [fine-tuning guide](https://platform.openai.com/docs/guides/legacy-fine-tuning/creating-training-data)
+              for more details.
+
+          batch_size: The batch size to use for training. The batch size is the number of training
+              examples used to train a single forward and backward pass.
+
+              By default, the batch size will be dynamically configured to be ~0.2% of the
+              number of examples in the training set, capped at 256 - in general, we've found
+              that larger batch sizes tend to work better for larger datasets.
+
+          classification_betas: If this is provided, we calculate F-beta scores at the specified beta values.
+              The F-beta score is a generalization of F-1 score. This is only used for binary
+              classification.
+
+              With a beta of 1 (i.e. the F-1 score), precision and recall are given the same
+              weight. A larger beta score puts more weight on recall and less on precision. A
+              smaller beta score puts more weight on precision and less on recall.
+
+          classification_n_classes: The number of classes in a classification task.
+
+              This parameter is required for multiclass classification.
+
+          classification_positive_class: The positive class in binary classification.
+
+              This parameter is needed to generate precision, recall, and F1 metrics when
+              doing binary classification.
+
+          compute_classification_metrics: If set, we calculate classification-specific metrics such as accuracy and F-1
+              score using the validation set at the end of every epoch. These metrics can be
+              viewed in the
+              [results file](https://platform.openai.com/docs/guides/legacy-fine-tuning/analyzing-your-fine-tuned-model).
+
+              In order to compute classification metrics, you must provide a
+              `validation_file`. Additionally, you must specify `classification_n_classes` for
+              multiclass classification or `classification_positive_class` for binary
+              classification.
+
+          hyperparameters: The hyperparameters used for the fine-tuning job.
+
+          learning_rate_multiplier: The learning rate multiplier to use for training. The fine-tuning learning rate
+              is the original learning rate used for pretraining multiplied by this value.
+
+              By default, the learning rate multiplier is the 0.05, 0.1, or 0.2 depending on
+              final `batch_size` (larger learning rates tend to perform better with larger
+              batch sizes). We recommend experimenting with values in the range 0.02 to 0.2 to
+              see what produces the best results.
+
+          model: The name of the base model to fine-tune. You can select one of "ada", "babbage",
+              "curie", "davinci", or a fine-tuned model created after 2022-04-21 and before
+              2023-08-22. To learn more about these models, see the
+              [Models](https://platform.openai.com/docs/models) documentation.
+
+          prompt_loss_weight: The weight to use for loss on the prompt tokens. This controls how much the
+              model tries to learn to generate the prompt (as compared to the completion which
+              always has a weight of 1.0), and can add a stabilizing effect to training when
+              completions are short.
+
+              If prompts are extremely long (relative to completions), it may make sense to
+              reduce this weight so as to avoid over-prioritizing learning the prompt.
+
+          suffix: A string of up to 40 characters that will be added to your fine-tuned model
+              name.
+
+              For example, a `suffix` of "custom-model-name" would produce a model name like
+              `ada:ft-your-org:custom-model-name-2022-02-15-04-21-04`.
+
+          validation_file: The ID of an uploaded file that contains validation data.
+
+              If you provide this file, the data is used to generate validation metrics
+              periodically during fine-tuning. These metrics can be viewed in the
+              [fine-tuning results file](https://platform.openai.com/docs/guides/legacy-fine-tuning/analyzing-your-fine-tuned-model).
+              Your train and validation data should be mutually exclusive.
+
+              Your dataset must be formatted as a JSONL file, where each validation example is
+              a JSON object with the keys "prompt" and "completion". Additionally, you must
+              upload your file with the purpose `fine-tune`.
+
+              See the
+              [fine-tuning guide](https://platform.openai.com/docs/guides/legacy-fine-tuning/creating-training-data)

+
+        Args:
+          training_file: The ID of an uploaded file that contains training data.
+
+              See [upload file](https://platform.openai.com/docs/api-reference/files/upload)
+              for how to upload a file.
+
+              Your dataset must be formatted as a JSONL file, where each training example is a
+              JSON object with the keys "prompt" and "completion". Additionally, you must
+              upload your file with the purpose `fine-tune`.
+
+              See the
+              [fine-tuning guide](https://platform.openai.com/docs/guides/legacy-fine-tuning/creating-training-data)
+              for more details.
+
+          batch_size: The batch size to use for training. The batch size is the number of training
+              examples used to train a single forward and backward pass.
+
+              By default, the batch size will be dynamically configured to be ~0.2% of the
+              number of examples in the training set, capped at 256 - in general, we've found
+              that larger batch sizes tend to work better for larger datasets.
+
+          classification_betas: If this is provided, we calculate F-beta scores at the specified beta values.
+              The F-beta score is a generalization of F-1 score. This is only used for binary
+              classification.
+
+              With a beta of 1 (i.e. the F-1 score), precision and recall are given the same
+              weight. A larger beta score puts more weight on recall and less on precision. A
+              smaller beta score puts more weight on precision and less on recall.
+
+          classification_n_classes: The number of classes in a classification task.
+
+              This parameter is required for multiclass classification.
+
+          classification_positive_class: The positive class in binary classification.
+
+              This parameter is needed to generate precision, recall, and F1 metrics when
+              doing binary classification.
+
+          compute_classification_metrics: If set, we calculate classification-specific metrics such as accuracy and F-1
+              score using the validation set at the end of every epoch. These metrics can be
+              viewed in the
+              [results file](https://platform.openai.com/docs/guides/legacy-fine-tuning/analyzing-your-fine-tuned-model).
+
+              In order to compute classification metrics, you must provide a
+              `validation_file`. Additionally, you must specify `classification_n_classes` for
+              multiclass classification or `classification_positive_class` for binary
+              classification.
+
+          hyperparameters: The hyperparameters used for the fine-tuning job.
+
+          learning_rate_multiplier: The learning rate multiplier to use for training. The fine-tuning learning rate
+              is the original learning rate used for pretraining multiplied by this value.
+
+              By default, the learning rate multiplier is the 0.05, 0.1, or 0.2 depending on
+              final `batch_size` (larger learning rates tend to perform better with larger
+              batch sizes). We recommend experimenting with values in the range 0.02 to 0.2 to
+              see what produces the best results.
+
+          model: The name of the base model to fine-tune. You can select one of "ada", "babbage",
+              "curie", "davinci", or a fine-tuned model created after 2022-04-21 and before
+              2023-08-22. To learn more about these models, see the
+              [Models](https://platform.openai.com/docs/models) documentation.
+
+          prompt_loss_weight: The weight to use for loss on the prompt tokens. This controls how much the
+              model tries to learn to generate the prompt (as compared to the completion which
+              always has a weight of 1.0), and can add a stabilizing effect to training when
+              completions are short.
+
+              If prompts are extremely long (relative to completions), it may make sense to
+              reduce this weight so as to avoid over-prioritizing learning the prompt.
+
+          suffix: A string of up to 40 characters that will be added to your fine-tuned model
+              name.
+
+              For example, a `suffix` of "custom-model-name" would produce a model name like
+              `ada:ft-your-org:custom-model-name-2022-02-15-04-21-04`.
+
+          validation_file: The ID of an uploaded file that contains validation data.
+
+              If you provide this file, the data is used to generate validation metrics
+              periodically during fine-tuning. These metrics can be viewed in the
+              [fine-tuning results file](https://platform.openai.com/docs/guides/legacy-fine-tuning/analyzing-your-fine-tuned-model).
+              Your train and validation data should be mutually exclusive.
+
+              Your dataset must be formatted as a JSONL file, where each validation example is
+              a JSON object with the keys "prompt" and "completion". Additionally, you must
+              upload your file with the purpose `fine-tune`.
+
+              See the

+              name.
+
+              For example, a `suffix` of "custom-model-name" would produce a model name like
+              `ft:gpt-3.5-turbo:openai:custom-model-name:7p4lURel`.
+
+          validation_file: The ID of an uploaded file that contains validation data.
+
+              If you provide this file, the data is used to generate validation metrics
+              periodically during fine-tuning. These metrics can be viewed in the fine-tuning
+              results file. The same data should not be present in both train and validation
+              files.
+
+              Your dataset must be formatted as a JSONL file. You must upload your file with
+              the purpose `fine-tune`.
+
+              See the [fine-tuning guide](https://platform.openai.com/docs/guides/fine-tuning)

+       same key in the query are NOT cleaned; i.e. "a=1&a=2" and "a=2&a=1" are

+    # 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into

+    # a *different* version of Python the entry points will be wrong. The
+    # correct fix for this is to enhance the metadata to be able to describe
+    # such versioned entry points, but that won't happen till Metadata 2.0 is
+    # available.
+    # In the meantime, projects using versioned entry points will either have

+    # is available.

+
+# This prober doesn't actually recognize a language or a charset.
+# It is a helper prober for the use of the Hebrew model probers
+
+### General ideas of the Hebrew charset recognition ###
+#
+# Four main charsets exist in Hebrew:
+# "ISO-8859-8" - Visual Hebrew
+# "windows-1255" - Logical Hebrew
+# "ISO-8859-8-I" - Logical Hebrew
+# "x-mac-hebrew" - ?? Logical Hebrew ??
+#
+# Both "ISO" charsets use a completely identical set of code points, whereas
+# "windows-1255" and "x-mac-hebrew" are two different proper supersets of
+# these code points. windows-1255 defines additional characters in the range
+# 0x80-0x9F as some misc punctuation marks as well as some Hebrew-specific
+# diacritics and additional 'Yiddish' ligature letters in the range 0xc0-0xd6.
+# x-mac-hebrew defines similar additional code points but with a different
+# mapping.
+#
+# As far as an average Hebrew text with no diacritics is concerned, all four
+# charsets are identical with respect to code points. Meaning that for the
+# main Hebrew alphabet, all four map the same values to all 27 Hebrew letters
+# (including final letters).
+#
+# The dominant difference between these charsets is their directionality.
+# "Visual" directionality means that the text is ordered as if the renderer is
+# not aware of a BIDI rendering algorithm. The renderer sees the text and
+# draws it from left to right. The text itself when ordered naturally is read
+# backwards. A buffer of Visual Hebrew generally looks like so:
+# "[last word of first line spelled backwards] [whole line ordered backwards
+# and spelled backwards] [first word of first line spelled backwards]
+# [end of line] [last word of second line] ... etc' "
+# adding punctuation marks, numbers and English text to visual text is
+# naturally also "visual" and from left to right.
+#
+# "Logical" directionality means the text is ordered "naturally" according to
+# the order it is read. It is the responsibility of the renderer to display
+# the text from right to left. A BIDI algorithm is used to place general
+# punctuation marks, numbers and English text in the text.
+#
+# Texts in x-mac-hebrew are almost impossible to find on the Internet. From
+# what little evidence I could find, it seems that its general directionality
+# is Logical.
+#
+# To sum up all of the above, the Hebrew probing mechanism knows about two
+# charsets:
+# Visual Hebrew - "ISO-8859-8" - backwards text - Words and sentences are
+#    backwards while line order is natural. For charset recognition purposes
+#    the line order is unimportant (In fact, for this implementation, even
+#    word order is unimportant).
+# Logical Hebrew - "windows-1255" - normal, naturally ordered text.
+#
+# "ISO-8859-8-I" is a subset of windows-1255 and doesn't need to be
+#    specifically identified.
+# "x-mac-hebrew" is also identified as windows-1255. A text in x-mac-hebrew
+#    that contain special punctuation marks or diacritics is displayed with
+#    some unconverted characters showing as question marks. This problem might
+#    be corrected using another model prober for x-mac-hebrew. Due to the fact
+#    that x-mac-hebrew texts are so rare, writing another model prober isn't
+#    worth the effort and performance hit.
+#
+#### The Prober ####
+#
+# The prober is divided between two SBCharSetProbers and a HebrewProber,
+# all of which are managed, created, fed data, inquired and deleted by the
+# SBCSGroupProber. The two SBCharSetProbers identify that the text is in
+# fact some kind of Hebrew, Logical or Visual. The final decision about which
+# one is it is made by the HebrewProber by combining final-letter scores
+# with the scores of the two SBCharSetProbers to produce a final answer.
+#
+# The SBCSGroupProber is responsible for stripping the original text of HTML
+# tags, English characters, numbers, low-ASCII punctuation characters, spaces
+# and new lines. It reduces any sequence of such characters to a single space.
+# The buffer fed to each prober in the SBCS group prober is pure text in
+# high-ASCII.
+# The two SBCharSetProbers (model probers) share the same language model:
+# Win1255Model.
+# The first SBCharSetProber uses the model normally as any other
+# SBCharSetProber does, to recognize windows-1255, upon which this model was
+# built. The second SBCharSetProber is told to make the pair-of-letter
+# lookup in the language model backwards. This in practice exactly simulates
+# a visual Hebrew model using the windows-1255 logical Hebrew model.
+#
+# The HebrewProber is not using any language model. All it does is look for
+# final-letter evidence suggesting the text is either logical Hebrew or visual
+# Hebrew. Disjointed from the model probers, the results of the HebrewProber
+# alone are meaningless. HebrewProber always returns 0.00 as confidence
+# since it never identifies a charset by itself. Instead, the pointer to the
+# HebrewProber is passed to the model probers as a helper "Name Prober".
+# When the Group prober receives a positive identification from any prober,
+# it asks for the name of the charset identified. If the prober queried is a
+# Hebrew model prober, the model prober forwards the call to the
+# HebrewProber to make the final decision. In the HebrewProber, the
+# decision is made according to the final-letters scores maintained and Both
+# model probers scores. The answer is returned in the form of the name of the
+# charset identified, either "windows-1255" or "ISO-8859-8".

+The ``distro`` package (``distro`` stands for Linux Distribution) provides
+information about the Linux distribution it runs on, such as a reliable
+machine-readable distro ID, or version information.
+
+It is the recommended replacement for Python's original
+:py:func:`platform.linux_distribution` function, but it provides much more
+functionality. An alternative implementation became necessary because Python
+3.5 deprecated this function, and Python 3.8 removed it altogether. Its
+predecessor function :py:func:`platform.dist` was already deprecated since
+Python 2.6 and removed in Python 3.8. Still, there are many cases in which
+access to OS distribution information is needed. See `Python issue 1322
+<https://bugs.python.org/issue1322>`_ for more information.

+
+    * blanks (which should not be there anyway) are translated to underscores,
+

+      `normalization tables`_. The purpose of this normalization is to ensure

+      in the OS distributions. A common reason for an incompatible change is
+      the addition of an os-release file, or the addition of the lsb_release

+        Used as `file_like.read(read_size)`. (default: `min(16*1024, max_buffer_size)`)
+
+    :param bool use_list:
+        If true, unpack msgpack array to Python list.
+        Otherwise, unpack to Python tuple. (default: True)
+
+    :param bool raw:
+        If true, unpack msgpack raw to Python bytes.
+        Otherwise, unpack to Python str by decoding with UTF-8 encoding (default).
+
+    :param int timestamp:
+        Control how timestamp type is unpacked:
+
+            0 - Timestamp
+            1 - float  (Seconds from the EPOCH)

+        contains invalid UTF-8 string.
+
+    :param int max_buffer_size:
+        Limits size of data waiting unpacked.  0 means 2**32-1.
+        The default value is 100*1024*1024 (100MiB).
+        Raises `BufferFull` exception when it is insufficient.
+        You should set this parameter when unpacking data from untrusted source.

+        astream.write(packer.pack(a))
+        astream.write(packer.pack(b))
+
+    Packer's constructor has some keyword arguments:
+
+    :param callable default:
+        Convert user type to builtin type that Packer supports.
+        See also simplejson's document.
+
+    :param bool use_single_float:
+        Use single precision float type for float. (default: False)
+
+    :param bool autoreset:
+        Reset buffer after each pack and return its content as `bytes`. (default: True).
+        If set this to false, use `bytes()` to get content and `.reset()` to clear buffer.
+
+    :param bool use_bin_type:
+        Use bin type introduced in msgpack spec 2.0 for bytes.
+        It also enables str8 type for unicode. (default: True)
+
+    :param bool strict_types:
+        If set to true, types will be checked to be exact. Derived classes
+        from serializable types will not be serialized and will be
+        treated as unsupported type and forwarded to default.
+        Additionally tuples will not be serialized as lists.
+        This is useful when trying to implement accurate serialization
+        for python types.
+
+    :param bool datetime:
+        If set to true, datetime with tzinfo is packed into Timestamp type.
+        Note that the tzinfo is stripped in the timestamp.
+        You can get UTC datetime with `timestamp=3` option of the Unpacker.
+        (Python 2 is not supported).
+
+    :param str unicode_errors:
+        The error handler for encoding unicode. (default: 'strict')
+        DO NOT USE THIS!!  This option is kept for very specific usage.
+
+    Example of streaming deserialize from file-like object::
+
+        unpacker = Unpacker(file_like)
+        for o in unpacker:

+    Example of streaming deserialize from socket::
+

+        while True:
+            buf = sock.recv(1024**2)

+Package resource API
+--------------------
+
+A resource is a logical file contained within a package, or a logical
+subdirectory thereof.  The package resource API expects resource names
+to have their path parts separated with ``/``, *not* whatever the local
+path separator is.  Do not use os.path operations to manipulate resource
+names being passed into the API.
+
+The package resource API is designed to work with normal filesystem packages,
+.egg files, and unpacked .egg files.  It can also work in a limited way with
+.zip files and with custom PEP 302 loaders that support the ``get_data()``
+method.
+
+This module is deprecated. Users are directed to :mod:`importlib.resources`,
+:mod:`importlib.metadata` and :pypi:`packaging` instead.

+    Pygments
+    ~~~~~~~~
+
+    Pygments is a syntax highlighting package written in Python.
+
+    It is a generic syntax highlighter for general use in all kinds of software
+    such as forum systems, wikis or other applications that need to prettify
+    source code. Highlights are:
+
+    * a wide range of common languages and markup formats is supported
+    * special attention is paid to details, increasing quality by a fair amount
+    * support for new languages and formats are added easily
+    * a number of output formats, presently HTML, LaTeX, RTF, SVG, all image
+      formats that PIL supports, and ANSI sequences
+    * it is usable as a command-line tool and as a library
+    * ... and it highlights even Brainfuck!
+
+    The `Pygments master branch`_ is installable with ``easy_install Pygments==dev``.

+class HtmlFormatter(Formatter):
+    r"""
+    Format tokens as HTML 4 ``<span>`` tags. By default, the content is enclosed
+    in a ``<pre>`` tag, itself wrapped in a ``<div>`` tag (but see the `nowrap` option).
+    The ``<div>``'s CSS class can be set by the `cssclass` option.
+
+    If the `linenos` option is set to ``"table"``, the ``<pre>`` is
+    additionally wrapped inside a ``<table>`` which has one row and two
+    cells: one containing the line numbers and one containing the code.
+    Example:
+
+    .. sourcecode:: html
+
+        <div class="highlight" >
+        <table><tr>
+          <td class="linenos" title="click to toggle"
+            onclick="with (this.firstChild.style)
+                     { display = (display == '') ? 'none' : '' }">
+            <pre>1
+            2</pre>
+          </td>
+          <td class="code">
+            <pre><span class="Ke">def </span><span class="NaFu">foo</span>(bar):
+              <span class="Ke">pass</span>
+            </pre>
+          </td>
+        </tr></table></div>
+
+    (whitespace added to improve clarity).
+
+    A list of lines can be specified using the `hl_lines` option to make these
+    lines highlighted (as of Pygments 0.11).
+
+    With the `full` option, a complete HTML 4 document is output, including
+    the style definitions inside a ``<style>`` tag, or in a separate file if
+    the `cssfile` option is given.
+
+    When `tagsfile` is set to the path of a ctags index file, it is used to
+    generate hyperlinks from names to their definition.  You must enable
+    `lineanchors` and run ctags with the `-n` option for this to work.  The
+    `python-ctags` module from PyPI must be installed to use this feature;
+    otherwise a `RuntimeError` will be raised.
+
+    The `get_style_defs(arg='')` method of a `HtmlFormatter` returns a string
+    containing CSS rules for the CSS classes used by the formatter. The
+    argument `arg` can be used to specify additional CSS selectors that
+    are prepended to the classes. A call `fmter.get_style_defs('td .code')`
+    would result in the following CSS classes:
+
+    .. sourcecode:: css
+
+        td .code .kw { font-weight: bold; color: #00FF00 }
+        td .code .cm { color: #999999 }
+        ...
+
+    If you have Pygments 0.6 or higher, you can also pass a list or tuple to the
+    `get_style_defs()` method to request multiple prefixes for the tokens:
+
+    .. sourcecode:: python
+
+        formatter.get_style_defs(['div.syntax pre', 'pre.syntax'])
+
+    The output would then look like this:
+
+    .. sourcecode:: css
+
+        div.syntax pre .kw,
+        pre.syntax .kw { font-weight: bold; color: #00FF00 }
+        div.syntax pre .cm,
+        pre.syntax .cm { color: #999999 }
+        ...
+
+    Additional options accepted:
+
+    `nowrap`
+        If set to ``True``, don't add a ``<pre>`` and a ``<div>`` tag
+        around the tokens. This disables most other options (default: ``False``).
+
+    `full`
+        Tells the formatter to output a "full" document, i.e. a complete
+        self-contained document (default: ``False``).
+
+    `title`
+        If `full` is true, the title that should be used to caption the
+        document (default: ``''``).
+
+    `style`
+        The style to use, can be a string or a Style subclass (default:
+        ``'default'``). This option has no effect if the `cssfile`
+        and `noclobber_cssfile` option are given and the file specified in
+        `cssfile` exists.
+
+    `noclasses`
+        If set to true, token ``<span>`` tags (as well as line number elements)
+        will not use CSS classes, but inline styles. This is not recommended
+        for larger pieces of code since it increases output size by quite a bit
+        (default: ``False``).
+
+    `classprefix`
+        Since the token types use relatively short class names, they may clash
+        with some of your own class names. In this case you can use the
+        `classprefix` option to give a string to prepend to all Pygments-generated
+        CSS class names for token types.
+        Note that this option also affects the output of `get_style_defs()`.
+
+    `cssclass`
+        CSS class for the wrapping ``<div>`` tag (default: ``'highlight'``).
+        If you set this option, the default selector for `get_style_defs()`
+        will be this class.
+
+        .. versionadded:: 0.9
+           If you select the ``'table'`` line numbers, the wrapping table will
+           have a CSS class of this string plus ``'table'``, the default is
+           accordingly ``'highlighttable'``.
+
+    `cssstyles`
+        Inline CSS styles for the wrapping ``<div>`` tag (default: ``''``).
+
+    `prestyles`
+        Inline CSS styles for the ``<pre>`` tag (default: ``''``).
+
+        .. versionadded:: 0.11
+
+    `cssfile`
+        If the `full` option is true and this option is given, it must be the
+        name of an external file. If the filename does not include an absolute
+        path, the file's path will be assumed to be relative to the main output
+        file's path, if the latter can be found. The stylesheet is then written
+        to this file instead of the HTML file.
+
+        .. versionadded:: 0.6
+
+    `noclobber_cssfile`
+        If `cssfile` is given and the specified file exists, the css file will
+        not be overwritten. This allows the use of the `full` option in
+        combination with a user specified css file. Default is ``False``.
+
+        .. versionadded:: 1.1
+
+    `linenos`
+        If set to ``'table'``, output line numbers as a table with two cells,
+        one containing the line numbers, the other the whole code.  This is
+        copy-and-paste-friendly, but may cause alignment problems with some
+        browsers or fonts.  If set to ``'inline'``, the line numbers will be
+        integrated in the ``<pre>`` tag that contains the code (that setting
+        is *new in Pygments 0.8*).
+
+        For compatibility with Pygments 0.7 and earlier, every true value
+        except ``'inline'`` means the same as ``'table'`` (in particular, that
+        means also ``True``).
+
+        The default value is ``False``, which means no line numbers at all.
+
+        **Note:** with the default ("table") line number mechanism, the line
+        numbers and code can have different line heights in Internet Explorer
+        unless you give the enclosing ``<pre>`` tags an explicit ``line-height``
+        CSS property (you get the default line spacing with ``line-height:
+        125%``).
+
+    `hl_lines`
+        Specify a list of lines to be highlighted. The line numbers are always
+        relative to the input (i.e. the first line is line 1) and are
+        independent of `linenostart`.
+
+        .. versionadded:: 0.11
+
+    `linenostart`
+        The line number for the first line (default: ``1``).
+
+    `linenostep`
+        If set to a number n > 1, only every nth line number is printed.
+
+    `linenospecial`
+        If set to a number n > 0, every nth line number is given the CSS
+        class ``"special"`` (default: ``0``).
+
+    `nobackground`
+        If set to ``True``, the formatter won't output the background color
+        for the wrapping element (this automatically defaults to ``False``
+        when there is no wrapping element [eg: no argument for the
+        `get_syntax_defs` method given]) (default: ``False``).
+
+        .. versionadded:: 0.6
+
+    `lineseparator`
+        This string is output between lines of code. It defaults to ``"\n"``,
+        which is enough to break a line inside ``<pre>`` tags, but you can
+        e.g. set it to ``"<br>"`` to get HTML line breaks.
+
+        .. versionadded:: 0.7
+
+    `lineanchors`
+        If set to a nonempty string, e.g. ``foo``, the formatter will wrap each
+        output line in an anchor tag with an ``id`` (and `name`) of ``foo-linenumber``.
+        This allows easy linking to certain lines.
+
+        .. versionadded:: 0.9
+
+    `linespans`
+        If set to a nonempty string, e.g. ``foo``, the formatter will wrap each
+        output line in a span tag with an ``id`` of ``foo-linenumber``.
+        This allows easy access to lines via javascript.
+
+        .. versionadded:: 1.6
+
+    `anchorlinenos`
+        If set to `True`, will wrap line numbers in <a> tags. Used in
+        combination with `linenos` and `lineanchors`.
+
+    `tagsfile`
+        If set to the path of a ctags file, wrap names in anchor tags that
+        link to their definitions. `lineanchors` should be used, and the
+        tags file should specify line numbers (see the `-n` option to ctags).
+
+        .. versionadded:: 1.6
+
+    `tagurlformat`
+        A string formatting pattern used to generate links to ctags definitions.
+        Available variables are `%(path)s`, `%(fname)s` and `%(fext)s`.
+        Defaults to an empty string, resulting in just `#prefix-number` links.
+
+        .. versionadded:: 1.6
+
+    `filename`
+        A string used to generate a filename when rendering ``<pre>`` blocks,
+        for example if displaying source code. If `linenos` is set to
+        ``'table'`` then the filename will be rendered in an initial row
+        containing a single `<th>` which spans both columns.
+
+        .. versionadded:: 2.1
+
+    `wrapcode`
+        Wrap the code inside ``<pre>`` blocks using ``<code>``, as recommended
+        by the HTML5 specification.
+
+        .. versionadded:: 2.4
+
+    `debug_token_types`
+        Add ``title`` attributes to all token ``<span>`` tags that show the
+        name of the token.
+
+        .. versionadded:: 2.10
+
+
+    **Subclassing the HTML formatter**
+
+    .. versionadded:: 0.7
+
+    The HTML formatter is now built in a way that allows easy subclassing, thus
+    customizing the output HTML code. The `format()` method calls
+    `self._format_lines()` which returns a generator that yields tuples of ``(1,
+    line)``, where the ``1`` indicates that the ``line`` is a line of the
+    formatted source code.
+
+    If the `nowrap` option is set, the generator is the iterated over and the
+    resulting HTML is output.
+
+    Otherwise, `format()` calls `self.wrap()`, which wraps the generator with
+    other generators. These may add some HTML code to the one generated by
+    `_format_lines()`, either by modifying the lines generated by the latter,
+    then yielding them again with ``(1, line)``, and/or by yielding other HTML
+    code before or after the lines, with ``(0, html)``. The distinction between
+    source lines and other code makes it possible to wrap the generator multiple
+    times.
+
+    The default `wrap()` implementation adds a ``<div>`` and a ``<pre>`` tag.
+
+    A custom `HtmlFormatter` subclass could look like this:
+
+    .. sourcecode:: python
+
+        class CodeHtmlFormatter(HtmlFormatter):
+
+            def wrap(self, source, *, include_div):
+                return self._wrap_code(source)
+
+            def _wrap_code(self, source):
+                yield 0, '<code>'
+                for i, t in source:
+                    if i == 1:
+                        # it's a line of formatted code
+                        t += '<br>'
+                    yield i, t
+                yield 0, '</code>'
+
+    This results in wrapping the formatted lines with a ``<code>`` tag, where the
+    source lines are broken using ``<br>`` tags.
+
+    After calling `wrap()`, the `format()` method also adds the "line numbers"
+    and/or "full document" wrappers if the respective options are set. Then, all
+    HTML yielded by the wrapped generator is output.

+## Small explanation of the mess below :)
+#
+# The previous version of the LaTeX formatter just assigned a command to
+# each token type defined in the current style.  That obviously is
+# problematic if the highlighted code is produced for a different style
+# than the style commands themselves.
+#
+# This version works much like the HTML formatter which assigns multiple
+# CSS classes to each <span> tag, from the most specific to the least
+# specific token type, thus falling back to the parent token type if one
+# is not defined.  Here, the classes are there too and use the same short
+# forms given in token.STANDARD_TYPES.
+#
+# Highlighted code now only uses one custom command, which by default is
+# \PY and selectable by the commandprefix option (and in addition the
+# escapes \PYZat, \PYZlb and \PYZrb which haven't been renamed for
+# backwards compatibility purposes).
+#
+# \PY has two arguments: the classes, separated by +, and the text to
+# render in that style.  The classes are resolved into the respective
+# style commands by magic, which serves to ignore unknown classes.
+#
+# The magic macros are:
+# * \PY@it, \PY@bf, etc. are unconditionally wrapped around the text
+#   to render in \PY@do.  Their definition determines the style.
+# * \PY@reset resets \PY@it etc. to do nothing.
+# * \PY@toks parses the list of classes, using magic inspired by the
+#   keyval package (but modified to use plusses instead of commas
+#   because fancyvrb redefines commas inside its environments).
+# * \PY@tok processes one class, calling the \PY@tok@classname command
+#   if it exists.
+# * \PY@tok@classname sets the \PY@it etc. to reflect the chosen style
+#   for its class.
+# * \PY resets the style, parses the classnames and then calls \PY@do.
+#
+# Tip: to read this code, print it out in substituted form using e.g.
+# >>> print STYLE_TEMPLATE % {'cp': 'PY'}

+class LatexFormatter(Formatter):
+    r"""
+    Format tokens as LaTeX code. This needs the `fancyvrb` and `color`
+    standard packages.
+
+    Without the `full` option, code is formatted as one ``Verbatim``
+    environment, like this:
+
+    .. sourcecode:: latex
+
+        \begin{Verbatim}[commandchars=\\\{\}]
+        \PY{k}{def }\PY{n+nf}{foo}(\PY{n}{bar}):
+            \PY{k}{pass}
+        \end{Verbatim}
+
+    Wrapping can be disabled using the `nowrap` option.
+
+    The special command used here (``\PY``) and all the other macros it needs
+    are output by the `get_style_defs` method.
+
+    With the `full` option, a complete LaTeX document is output, including
+    the command definitions in the preamble.
+
+    The `get_style_defs()` method of a `LatexFormatter` returns a string
+    containing ``\def`` commands defining the macros needed inside the
+    ``Verbatim`` environments.
+
+    Additional options accepted:
+
+    `nowrap`
+        If set to ``True``, don't wrap the tokens at all, not even inside a
+        ``\begin{Verbatim}`` environment. This disables most other options
+        (default: ``False``).
+
+    `style`
+        The style to use, can be a string or a Style subclass (default:
+        ``'default'``).
+
+    `full`
+        Tells the formatter to output a "full" document, i.e. a complete
+        self-contained document (default: ``False``).
+
+    `title`
+        If `full` is true, the title that should be used to caption the
+        document (default: ``''``).
+
+    `docclass`
+        If the `full` option is enabled, this is the document class to use
+        (default: ``'article'``).
+
+    `preamble`
+        If the `full` option is enabled, this can be further preamble commands,
+        e.g. ``\usepackage`` (default: ``''``).
+
+    `linenos`
+        If set to ``True``, output line numbers (default: ``False``).
+
+    `linenostart`
+        The line number for the first line (default: ``1``).
+
+    `linenostep`
+        If set to a number n > 1, only every nth line number is printed.
+
+    `verboptions`
+        Additional options given to the Verbatim environment (see the *fancyvrb*
+        docs for possible values) (default: ``''``).
+
+    `commandprefix`
+        The LaTeX commands used to produce colored output are constructed
+        using this prefix and some letters (default: ``'PY'``).
+
+        .. versionadded:: 0.7
+        .. versionchanged:: 0.10
+           The default is now ``'PY'`` instead of ``'C'``.
+
+    `texcomments`
+        If set to ``True``, enables LaTeX comment lines.  That is, LaTex markup
+        in comment tokens is not escaped so that LaTeX can render it (default:
+        ``False``).
+
+        .. versionadded:: 1.2
+
+    `mathescape`
+        If set to ``True``, enables LaTeX math mode escape in comments. That
+        is, ``'$...$'`` inside a comment will trigger math mode (default:
+        ``False``).
+
+        .. versionadded:: 1.2
+
+    `escapeinside`
+        If set to a string of length 2, enables escaping to LaTeX. Text
+        delimited by these 2 characters is read as LaTeX code and
+        typeset accordingly. It has no effect in string literals. It has
+        no effect in comments if `texcomments` or `mathescape` is
+        set. (default: ``''``).
+
+        .. versionadded:: 2.0
+
+    `envname`
+        Allows you to pick an alternative environment name replacing Verbatim.
+        The alternate environment still has to support Verbatim's option syntax.
+        (default: ``'Verbatim'``).

+        Starting offset in Y direction, defaults to the font size if it is given

+

+        roughly be the text size plus 5.  It defaults to that value if the text

+
+    `spacehack`
+        Convert spaces in the source to ``&#160;``, which are non-breaking
+        spaces.  SVG provides the ``xml:space`` attribute to control how
+        whitespace inside tags is handled, in theory, the ``preserve`` value
+        could be used to keep all whitespace as-is.  However, many current SVG
+        viewers don't obey that rule, so this option is provided as a workaround
+        and defaults to ``True``.

+pyparsing module - Classes and methods to define and execute parsing grammars
+=============================================================================
+
+The pyparsing module is an alternative approach to creating and
+executing simple grammars, vs. the traditional lex/yacc approach, or the
+use of regular expressions.  With pyparsing, you don't need to learn
+a new syntax for defining grammars or matching expressions - the parsing
+module provides a library of classes that you use to construct the
+grammar directly in Python.
+
+Here is a program to parse "Hello, World!" (or any greeting of the form
+``"<salutation>, <addressee>!"``), built up using :class:`Word`,
+:class:`Literal`, and :class:`And` elements
+(the :meth:`'+'<ParserElement.__add__>` operators create :class:`And` expressions,
+and the strings are auto-converted to :class:`Literal` expressions)::
+
+    from pip._vendor.pyparsing import Word, alphas
+
+    # define grammar of a greeting
+    greet = Word(alphas) + "," + Word(alphas) + "!"
+
+    hello = "Hello, World!"
+    print(hello, "->", greet.parse_string(hello))
+
+The program outputs the following::
+
+    Hello, World! -> ['Hello', ',', 'World', '!']
+
+The Python representation of the grammar is quite readable, owing to the
+self-explanatory class names, and the use of :class:`'+'<And>`,
+:class:`'|'<MatchFirst>`, :class:`'^'<Or>` and :class:`'&'<Each>` operators.
+
+The :class:`ParseResults` object returned from
+:class:`ParserElement.parse_string` can be
+accessed as a nested list, a dictionary, or an object with named
+attributes.
+
+The pyparsing module handles some of the problems that are typically
+vexing when writing text parsers:
+
+  - extra or missing whitespace (the above program will also handle
+    "Hello,World!", "Hello  ,  World  !", etc.)
+  - quoted strings
+  - embedded comments
+
+
+Getting Started -
+-----------------
+Visit the classes :class:`ParserElement` and :class:`ParseResults` to
+see the base classes that most other pyparsing
+classes inherit from. Use the docstrings for examples of how to:
+
+ - construct literal match expressions from :class:`Literal` and
+   :class:`CaselessLiteral` classes
+ - construct character word-group expressions using the :class:`Word`
+   class
+ - see how to create repetitive expressions using :class:`ZeroOrMore`
+   and :class:`OneOrMore` classes
+ - use :class:`'+'<And>`, :class:`'|'<MatchFirst>`, :class:`'^'<Or>`,
+   and :class:`'&'<Each>` operators to combine simple expressions into
+   more complex ones
+ - associate names with your parsed results using
+   :class:`ParserElement.set_results_name`
+ - access the parsed data, which is returned as a :class:`ParseResults`
+   object
+ - find some helpful expression short-cuts like :class:`DelimitedList`
+   and :class:`one_of`
+ - find more useful common expressions in the :class:`pyparsing_common`
+   namespace class

+
+        Parse actions can be called to perform data conversions, do extra validation,
+        update external data structures, or enhance or replace the parsed tokens.
+        Each parse action ``fn`` is a callable method with 0-3 arguments, called as
+        ``fn(s, loc, toks)`` , ``fn(loc, toks)`` , ``fn(toks)`` , or just ``fn()`` , where:

+        - ``toks`` = a list of the matched tokens, packaged as a :class:`ParseResults` object
+
+        The parsed tokens are passed to the parse action as ParseResults. They can be
+        modified in place using list-style append, extend, and pop operations to update
+        the parsed list elements; and with dictionary-style item set and del operations
+        to add, update, or remove any named results. If the tokens are modified in place,
+        it is not necessary to return them with a return statement.
+
+        Parse actions can also completely replace the given tokens, with another ``ParseResults``
+        object, or with some entirely different object (common for parse actions that perform data
+        conversions). A convenient way to build a new parse result is to define the values
+        using a dict, and then create the return value using :class:`ParseResults.from_dict`.

+        If None is passed as the ``fn`` parse action, all previously added parse actions for this
+        expression are cleared.
+
+        Optional keyword arguments:
+
+        - ``call_during_try`` = (default= ``False``) indicate if parse action should be run during
+          lookaheads and alternate testing. For parse actions that have side effects, it is
+          important to only call the parse action once it is determined that it is being
+          called as part of a successful parse. For parse actions that perform additional
+          validation, then call_during_try should be passed as True, so that the validation
+          code is included in the preliminary "try" parses.
+
+        Note: the default parsing behavior is to expand tabs in the input string
+        before starting the parsing process.  See :class:`parse_string` for more
+        information on parsing strings containing ``<TAB>`` s, and suggested
+        methods to maintain a consistent view of the parsed string, the parse
+        location, and line and column positions within the parsed string.

+          an object with attributes if the given parser includes results names.
+
+        If the input string is required to match the entire grammar, ``parse_all`` flag must be set to ``True``. This
+        is also equivalent to ending the grammar with :class:`StringEnd`\\ ().
+
+        To report proper column numbers, ``parse_string`` operates on a copy of the input string where all tabs are
+        converted to spaces (8 spaces per tab, as per the default in ``string.expandtabs``). If the input string
+        contains tabs and the grammar uses parse actions that use the ``loc`` argument to index into the string
+        being parsed, one can ensure a consistent view of the input string by doing one of the following:
+
+        - calling ``parse_with_tabs`` on your grammar before calling ``parse_string`` (see :class:`parse_with_tabs`),
+        - define your parse action using the full ``(s,loc,toks)`` signature, and reference the input string using the
+          parse action's ``s`` argument, or
+        - explicitly expand the tabs in your input string before calling ``parse_string``.
+
+        Examples:
+

+
+        The parsing behavior varies by the inheriting class of this abstract class. Please refer to the children

+
+    :class:`srange` is useful for defining custom character set strings
+    for defining :class:`Word` expressions, using range notation from
+    regular expression character sets.
+
+    A common mistake is to use :class:`Word` to match a specific literal
+    string, as in ``Word("Address")``. Remember that :class:`Word`
+    uses the string argument to define *sets* of matchable characters.
+    This expression would match "Add", "AAA", "dAred", or any other word
+    made up of the characters 'A', 'd', 'r', 'e', and 's'. To match an
+    exact literal string, use :class:`Literal` or :class:`Keyword`.
+
+    pyparsing includes helper strings for building Words:
+
+    - :class:`alphas`
+    - :class:`nums`
+    - :class:`alphanums`
+    - :class:`hexnums`
+    - :class:`alphas8bit` (alphabetic characters in ASCII range 128-255
+      - accented, tilded, umlauted, etc.)
+    - :class:`punc8bit` (non-alphabetic characters in ASCII range
+      128-255 - currency, symbols, superscripts, diacriticals, etc.)
+    - :class:`printables` (any non-whitespace character)
+
+    ``alphas``, ``nums``, and ``printables`` are also defined in several
+    Unicode sets - see :class:`pyparsing_unicode``.
+
+    Example::
+
+        # a word composed of digits
+        integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9"))
+

+        # recurse twice, ..., until more recursion offers no benefit (we hit the bound).
+        #

+        # - to *match* a specific recursion level, and
+        # - to *search* the bounded recursion level
+        # and the two run concurrently. The *search* must *match* each recursion level
+        # to find the best possible match. This is handled by a memo table, which
+        # provides the previous match to the next level match attempt.
+        #

+      - ``parse_action`` is the parse action to be associated with
+        expressions matching this operator expression (the parse action

+    - ``lpar`` - expression for matching left-parentheses; if passed as a

+    (DEPRECATED - use :class:`IndentedBlock` class instead)
+    Helper method for defining space-delimited indentation blocks,
+    such as those used to define block statements in Python source code.
+
+    Parameters:
+
+    - ``blockStatementExpr`` - expression defining syntax of statement that
+      is repeated within the indented block
+    - ``indentStack`` - list created by caller to manage indentation stack
+      (multiple ``statementWithIndentedBlock`` expressions within a single
+      grammar should share a common ``indentStack``)
+    - ``indent`` - boolean indicating whether block must be indented beyond
+      the current level; set to ``False`` for block of left-most statements
+      (default= ``True``)
+
+    A valid block must contain at least one ``blockStatement``.

+    (Note that indentedBlock uses internal parse actions which make it

+Requests HTTP Library
+~~~~~~~~~~~~~~~~~~~~~
+
+Requests is an HTTP library, written in Python, for human beings.
+Basic GET usage:
+
+   >>> import requests
+   >>> r = requests.get('https://www.python.org')
+   >>> r.status_code
+   200
+   >>> b'Python is a programming language' in r.content
+   True
+
+... or POST:
+
+   >>> payload = dict(key1='value1', key2='value2')
+   >>> r = requests.post('https://httpbin.org/post', data=payload)
+   >>> print(r.text)
+   {
+     ...
+     "form": {
+       "key1": "value1",
+       "key2": "value2"
+     },
+     ...
+   }
+
+The other HTTP methods are supported - see `requests.api`. Full documentation
+is at <https://requests.readthedocs.io>.

+The ``codes`` object defines a mapping from common names for HTTP statuses
+to their numerical codes, accessible either as attributes or as dictionary
+items.
+
+Example::
+
+    >>> import requests
+    >>> requests.codes['temporary_redirect']
+    307
+    >>> requests.codes.teapot
+    418
+    >>> requests.codes['\o/']
+    200
+
+Some codes have multiple names, and both upper- and lower-case versions of
+the names are allowed. For example, ``codes.ok``, ``codes.OK``, and
+``codes.okay`` all correspond to the HTTP status code 200.

+
+        TypedDict creates a dictionary type such that a type checker will expect all
+        instances to have a certain set of keys, where each key is
+        associated with a value of a consistent type. This expectation
+        is not checked at runtime.
+
+        Usage::
+
+            class Point2D(TypedDict):
+                x: int
+                y: int
+                label: str
+
+            a: Point2D = {'x': 1, 'y': 2, 'label': 'good'}  # OK
+            b: Point2D = {'z': 3, 'label': 'bad'}           # Fails type check
+
+            assert Point2D(x=1, y=2, label='first') == dict(x=1, y=2, label='first')
+
+        The type info can be accessed via the Point2D.__annotations__ dict, and
+        the Point2D.__required_keys__ and Point2D.__optional_keys__ frozensets.
+        TypedDict supports an additional equivalent form::
+
+            Point2D = TypedDict('Point2D', {'x': int, 'y': int, 'label': str})
+
+        By default, all keys must be present in a TypedDict. It is possible
+        to override this by specifying totality::
+
+            class Point2D(TypedDict, total=False):
+                x: int
+                y: int
+
+        This means that a Point2D TypedDict can have any of the keys omitted. A type
+        checker is only expected to support a literal False or True as the value of
+        the total argument. True is the default, and makes all items defined in the
+        class body be required.
+
+        The Required and NotRequired special forms can also be used to mark
+        individual keys as being required or not required::
+
+            class Point2D(TypedDict):
+                x: int  # the "x" key must always be present (Required is the default)
+                y: NotRequired[int]  # the "y" key can be omitted
+
+        See PEP 655 for more details on Required and NotRequired.

+
+           P = ParamSpec('P')
+
+        Parameter specification variables exist primarily for the benefit of static
+        type checkers.  They are used to forward the parameter types of one
+        callable to another callable, a pattern commonly found in higher order
+        functions and decorators.  They are only valid when used in ``Concatenate``,
+        or s the first argument to ``Callable``. In Python 3.10 and higher,
+        they are also supported in user-defined Generics at runtime.
+        See class Generic for more information on generic types.  An
+        example for annotating a decorator::
+
+           T = TypeVar('T')
+           P = ParamSpec('P')
+
+           def add_logging(f: Callable[P, T]) -> Callable[P, T]:
+               '''A type-safe decorator to add logging to a function.'''
+               def inner(*args: P.args, **kwargs: P.kwargs) -> T:
+                   logging.info(f'{f.__name__} was called')
+                   return f(*args, **kwargs)
+               return inner
+
+           @add_logging
+           def add_two(x: float, y: float) -> float:

+
+        Parameter specification variables defined with covariant=True or
+        contravariant=True can be used to declare covariant or contravariant
+        generic types.  These keyword arguments are valid, but their actual semantics
+        are yet to be decided.  See PEP 612 for details.
+
+        Parameter specification variables can be introspected. e.g.:
+
+           P.__name__ == 'T'
+           P.__bound__ == None
+           P.__covariant__ == False
+           P.__contravariant__ == False
+
+        Note that only parameter specification variables defined in global scope can

+            Ts = TypeVarTuple('Ts')
+
+        In the same way that a normal type variable is a stand-in for a single
+        type such as ``int``, a type variable *tuple* is a stand-in for a *tuple*
+        type such as ``Tuple[int, str]``.
+
+        Type variable tuples can be used in ``Generic`` declarations.
+        Consider the following example::
+
+            class Array(Generic[*Ts]): ...
+
+        The ``Ts`` type variable tuple here behaves like ``tuple[T1, T2]``,
+        where ``T1`` and ``T2`` are type variables. To use these type variables
+        as type parameters of ``Array``, we must *unpack* the type variable tuple using
+        the star operator: ``*Ts``. The signature of ``Array`` then behaves
+        as if we had simply written ``class Array(Generic[T1, T2]): ...``.
+        In contrast to ``Generic[T1, T2]``, however, ``Generic[*Shape]`` allows
+        us to parameterise the class with an *arbitrary* number of type parameters.
+
+        Type variable tuples can be used anywhere a normal ``TypeVar`` can.
+        This includes class definitions, as shown above, as well as function
+        signatures and variable annotations::
+
+            class Array(Generic[*Ts]):
+

+        be a float or integer, which sets the timeout for the HTTP request,
+        or an instance of :class:`urllib3.util.Timeout` which gives you more
+        fine-grained control over request timeouts. After the constructor has
+        been parsed, this is always a `urllib3.util.Timeout` object.
+

+        connections will be created but they will not be saved once they've
+        been used.
+
+    :param block:
+        If set to True, no more than ``maxsize`` connections will be used at
+        a time. When no free connections are available, the call will block
+        until a connection has been released. This is a useful side effect for
+        particular multithreaded situations where one does not want to use more
+        than maxsize connections per host to prevent flooding.

+            If ``False``, then retries are disabled and any exception is raised
+            immediately. Also, instead of raising a MaxRetryError on redirects,

+            303, 307, 308). Each redirect counts as a retry. Disabling retries
+            will disable redirect, too.
+
+        :param assert_same_host:
+            If ``True``, will make sure that the host of the pool requests is
+            consistent else will raise HostChangedError. When ``False``, you can
+            use the pool on an HTTP proxy and request foreign hosts.

+            If specified, overrides the default timeout for this one
+            request. It may be a float (in seconds) or an instance of
+            :class:`urllib3.util.Timeout`.
+
+        :param pool_timeout:
+            If set and the pool is set to block=True, then this method will
+            block for ``pool_timeout`` seconds and raise EmptyPoolError if no
+            connection is available within the time period.
+
+        :param release_conn:
+            If False, then the urlopen call will not release the connection
+            back into the pool once a response is received (but will release if
+            you read the entire contents of the response such as when
+            `preload_content=True`). This is useful if you're not preloading
+            the response's content immediately. You will need to call
+            ``r.release_conn()`` on the response ``r`` to return the connection
+            back into the pool. If None, it takes the value of
+            ``response_kw.get('preload_content', True)``.
+
+        :param chunked:
+            If True, urllib3 will send the body using chunked transfer
+            encoding. Otherwise, urllib3 will send the body using the standard
+            content-length form. Defaults to False.
+
+        :param int body_pos:
+            Position to seek to in file-like body in the event of a retry or
+            redirect. Typically this won't need to be set because urllib3 will
+            auto-populate the value when needed.

+"""
+This module provides a pool manager that uses Google App Engine's
+`URLFetch Service <https://cloud.google.com/appengine/docs/python/urlfetch>`_.
+
+Example usage::
+
+    from pip._vendor.urllib3 import PoolManager
+    from pip._vendor.urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox
+
+    if is_appengine_sandbox():
+        # AppEngineManager uses AppEngine's URLFetch API behind the scenes
+        http = AppEngineManager()
+    else:
+        # PoolManager uses a socket-level API behind the scenes
+        http = PoolManager()
+
+    r = http.request('GET', 'https://google.com/')
+
+There are `limitations <https://cloud.google.com/appengine/docs/python/\
+urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be
+the best choice for your application. There are three options for using
+urllib3 on Google App Engine:
+
+1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is
+   cost-effective in many circumstances as long as your usage is within the
+   limitations.
+2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets.
+   Sockets also have `limitations and restrictions
+   <https://cloud.google.com/appengine/docs/python/sockets/\
+   #limitations-and-restrictions>`_ and have a lower free quota than URLFetch.
+   To use sockets, be sure to specify the following in your ``app.yaml``::
+
+        env_variables:
+            GAE_USE_SOCKETS_HTTPLIB : 'true'
+
+3. If you are using `App Engine Flexible
+<https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard
+:class:`PoolManager` without any configuration or special environment variables.

+TLS with SNI_-support for Python 2. Follow these instructions if you would
+like to verify TLS certificates in Python 2. Note, the default libraries do
+*not* do certificate checking; you need to do additional work to validate
+certificates yourself.
+
+This needs the following packages installed:
+
+* `pyOpenSSL`_ (tested with 16.0.0)
+* `cryptography`_ (minimum 1.3.4, from pyopenssl)
+* `idna`_ (minimum 2.0, from cryptography)
+
+However, pyopenssl depends on cryptography, which depends on idna, so while we
+use all three directly here we end up having relatively few packages required.
+
+You can install them with the following command:
+
+.. code-block:: bash
+
+    $ python -m pip install pyopenssl cryptography idna
+
+To activate certificate checking, call
+:func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code
+before you begin making HTTP requests. This can be done in a ``sitecustomize``
+module, or at any other time before your application begins using ``urllib3``,
+like this:
+
+.. code-block:: python
+
+    try:
+        import pip._vendor.urllib3.contrib.pyopenssl as pyopenssl
+        pyopenssl.inject_into_urllib3()
+    except ImportError:
+        pass
+
+Now you can use :mod:`urllib3` as you normally would, and it will support SNI
+when the required modules are installed.
+
+Activating this module also has the positive side effect of disabling SSL/TLS
+compression in Python 2 (see `CRIME attack`_).

+SecureTranport support for urllib3 via ctypes.
+
+This makes platform-native TLS available to urllib3 users on macOS without the
+use of a compiler. This is an important feature because the Python Package
+Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL
+that ships with macOS is not capable of doing TLSv1.2. The only way to resolve
+this is to give macOS users an alternative solution to the problem, and that
+solution is to use SecureTransport.
+
+We use ctypes here because this solution must not require a compiler. That's
+because pip is not allowed to require a compiler either.
+
+This is not intended to be a seriously long-term solution to this problem.
+The hope is that PEP 543 will eventually solve this issue for us, at which
+point we can retire this contrib module. But in the short term, we need to
+solve the impending tire fire that is Python on Mac without this kind of
+contrib module. So...here we are.
+
+To use this module, simply import and inject it::
+
+    import pip._vendor.urllib3.contrib.securetransport as securetransport
+    securetransport.inject_into_urllib3()
+
+Happy TLSing!

+library. An enormous debt is owed to him for blazing this trail for us. For

+This module contains provisional support for SOCKS proxies from within
+urllib3. This module supports SOCKS4, SOCKS4A (an extension of SOCKS4), and
+SOCKS5. To enable its functionality, either install PySocks or install this
+module with the ``socks`` extra.
+
+The SOCKS implementation supports the full range of urllib3 features. It also
+supports the following SOCKS features:
+
+- SOCKS4A (``proxy_url='socks4a://...``)
+- SOCKS4 (``proxy_url='socks4://...``)
+- SOCKS5 with remote DNS (``proxy_url='socks5h://...``)
+- SOCKS5 with local DNS (``proxy_url='socks5://...``)
+- Usernames and passwords for the SOCKS proxy
+
+.. note::
+   It is recommended to use ``socks5h://`` or ``socks4a://`` schemes in
+   your ``proxy_url`` to ensure that DNS resolution is done from the remote
+   server instead of client-side when connecting to a domain name.
+
+SOCKS4 supports IPv4 and domain names with the SOCKS4A extension. SOCKS5
+supports IPv4, IPv6, and domain names.
+
+When connecting to a SOCKS4 proxy the ``username`` portion of the ``proxy_url``
+will be sent as the ``userid`` section of the SOCKS request:
+
+.. code-block:: python
+
+    proxy_url="socks4a://<userid>@proxy-host"
+
+When connecting to a SOCKS5 proxy the ``username`` and ``password`` portion
+of the ``proxy_url`` will be sent as the username/password to authenticate
+with the proxy:
+
+.. code-block:: python
+
+    proxy_url="socks5h://<username>:<password>@proxy-host"

+    Each retry attempt will create a new Retry object with updated values, so

+
+    Retries can be defined as a default for a pool::
+
+        retries = Retry(connect=5, read=2, redirect=5)
+        http = PoolManager(retries=retries)
+        response = http.request('GET', 'http://example.com/')
+
+    Or per-request (which overrides the default for the pool)::
+
+        response = http.request('GET', 'http://example.com/', retries=Retry(10))
+
+    Retries can be disabled by passing ``False``::
+
+        response = http.request('GET', 'http://example.com/', retries=False)
+
+    Errors will be wrapped in :class:`~urllib3.exceptions.MaxRetryError` unless
+    retries are disabled, in which case the causing exception will be raised.
+
+    :param int total:
+        Total number of retries to allow. Takes precedence over other counts.
+
+        Set to ``None`` to remove this constraint and fall back on other
+        counts.
+
+        Set to ``0`` to fail on the first retry.
+
+        Set to ``False`` to disable and imply ``raise_on_redirect=False``.
+
+    :param int connect:
+        How many connection-related errors to retry on.
+
+        These are errors raised before the request is sent to the remote server,
+        which we assume has not triggered the server to process the request.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int read:
+        How many times to retry on read errors.
+
+        These errors are raised after the request was sent to the server, so the
+        request may have side-effects.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int redirect:
+        How many redirects to perform. Limit this to avoid infinite redirect
+        loops.
+
+        A redirect is a HTTP response with a status code 301, 302, 303, 307 or
+        308.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+        Set to ``False`` to disable and imply ``raise_on_redirect=False``.
+
+    :param int status:
+        How many times to retry on bad status codes.
+
+        These are retries made on responses, where status code matches
+        ``status_forcelist``.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int other:
+        How many times to retry on other errors.
+
+        Other errors are errors that are not connect, read, redirect or status errors.
+        These errors might be raised after the request was sent to the server, so the
+        request might have side-effects.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+        If ``total`` is not set, it's a good idea to set this to 0 to account
+        for unexpected edge cases and avoid infinite retry loops.
+
+    :param iterable allowed_methods:
+        Set of uppercased HTTP method verbs that we should retry on.
+
+        By default, we only retry on methods which are considered to be
+        idempotent (multiple requests with the same parameters end with the
+        same state). See :attr:`Retry.DEFAULT_ALLOWED_METHODS`.
+
+        Set to a ``False`` value to retry on any verb.
+
+        .. warning::
+
+            Previously this parameter was named ``method_whitelist``, that
+            usage is deprecated in v1.26.0 and will be removed in v2.0.
+
+    :param iterable status_forcelist:
+        A set of integer HTTP status codes that we should force a retry on.
+        A retry is initiated if the request method is in ``allowed_methods``
+        and the response status code is in ``status_forcelist``.
+
+        By default, this is disabled with ``None``.
+
+    :param float backoff_factor:
+        A backoff factor to apply between attempts after the second try
+        (most errors are resolved immediately by a second try without a
+        delay). urllib3 will sleep for::
+
+            {backoff factor} * (2 ** ({number of total retries} - 1))
+
+        seconds. If the backoff_factor is 0.1, then :func:`.sleep` will sleep
+        for [0.0s, 0.2s, 0.4s, ...] between retries. It will never be longer
+        than :attr:`Retry.DEFAULT_BACKOFF_MAX`.
+
+        By default, backoff is disabled (set to 0).
+
+    :param bool raise_on_redirect: Whether, if the number of redirects is
+        exhausted, to raise a MaxRetryError, or to return a response with a
+        response code in the 3xx range.
+
+    :param bool raise_on_status: Similar meaning to ``raise_on_redirect``:
+        whether we should raise an exception, or return a response,
+        if status falls in ``status_forcelist`` range and retries have
+        been exhausted.
+
+    :param tuple history: The history of the request encountered during
+        each call to :meth:`~Retry.increment`. The list is in the order
+        the requests occurred. Each list item is of class :class:`RequestHistory`.
+
+    :param bool respect_retry_after_header:
+        Whether to respect Retry-After header on status codes defined as
+        :attr:`Retry.RETRY_AFTER_STATUS_CODES` or not.
+
+    :param iterable remove_headers_on_redirect:
+        Sequence of headers to remove from the request when a response
+        indicating a redirect is returned before firing off the redirected
+        request.

+
+    Timeouts can be disabled by setting all the parameters to ``None``:
+

+
+       no_timeout = Timeout(connect=None, read=None)
+       response = http.request('GET', 'http://example.com/, timeout=no_timeout)

+        This combines the connect and read timeouts into one; the read timeout
+        will be set to the time leftover from the connect attempt. In the
+        event that both a connect timeout and a total are specified, or a read
+        timeout and a total are specified, the shorter timeout will be applied.
+
+        Defaults to None.

+
+    :param connect:
+        The maximum amount of time (in seconds) to wait for a connection
+        attempt to a server to succeed. Omitting the parameter will default the
+        connect timeout to the system default, probably `the global default
+        timeout in socket.py
+        <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_.

+
+    :param read:
+        The maximum amount of time (in seconds) to wait between consecutive
+        read operations for a response from the server. Omitting the parameter
+        will default the read timeout to the system default, probably `the
+        global default timeout in socket.py
+        <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_.
+        None will set an infinite timeout.
+
+    :type read: int, float, or None
+
+    .. note::
+
+        Many factors can affect the total amount of time for urllib3 to return
+        an HTTP response.
+
+        For example, Python's DNS resolver does not obey the timeout specified
+        on the socket. Other factors that can affect total request time include
+        high CPU load, high swap, the program running at a low priority level,
+        or other behaviors.
+
+        In addition, the read and total timeouts only measure the time between
+        read operations on the socket connecting the client and the server,
+        not the total amount of time for the request to return a complete
+        response. For most requests, the timeout is raised because the server
+        has not sent the first byte in the specified time. This is not always
+        the case; if a server streams one byte every fifteen seconds, a timeout
+        of 20 seconds will not trigger, even though the request will take
+        several minutes to complete.
+
+        If your goal is to cut off any request after a set amount of wall clock
+        time, consider having a second "watcher" thread to cut off a slow
+        request.

+# There are two types of APIs you can use for waiting on sockets: the fancy

+# select/poll. The stateful APIs are more efficient when you have a lots of
+# sockets to keep track of, because you can set them up once and then use them
+# lots of times. But we only ever want to wait on a single socket at a time
+# and don't want to keep track of state, so the stateless APIs are actually
+# more efficient. So we want to use select() or poll().
+#
+# Now, how do we choose between select() and poll()? On traditional Unixes,
+# select() has a strange calling convention that makes it slow, or fail
+# altogether, for high-numbered file descriptors. The point of poll() is to fix
+# that, so on Unixes, we prefer poll().
+#
+# On Windows, there is no poll() (or at least Python doesn't provide a wrapper
+# for it), but that's OK, because on Windows, select() doesn't have this
+# strange calling convention; plain select() works fine.

+# So: on Windows we use select(), and everywhere else we use poll(). We also
+# fall back to select() in case poll() is somehow broken or missing.

+
+## Pydantic V1.10 vs. V2
+
+Pydantic V2 is a ground-up rewrite that offers many new features, performance improvements, and some breaking changes compared to Pydantic V1.
+
+If you're using Pydantic V1 you may want to look at the
+[pydantic V1.10 Documentation](https://docs.pydantic.dev/) or,
+[`1.10.X-fixes` git branch](https://github.com/pydantic/pydantic/tree/1.10.X-fixes). Pydantic V2 also ships with the latest version of Pydantic V1 built in so that you can incrementally upgrade your code base and projects: `from pydantic import v1 as pydantic_v1`.
+
+## Help
+
+See [documentation](https://docs.pydantic.dev/) for more details.
+
+## Installation
+
+Install using `pip install -U pydantic` or `conda install pydantic -c conda-forge`.
+For more installation options to make Pydantic even faster,
+see the [Install](https://docs.pydantic.dev/install/) section in the documentation.
+
+## A Simple Example
+
+```python
+from datetime import datetime
+from typing import Optional
+from pydantic import BaseModel
+
+class User(BaseModel):
+    id: int
+    name: str = 'John Doe'
+    signup_ts: Optional[datetime] = None
+    friends: list[int] = []
+
+external_data = {'id': '123', 'signup_ts': '2017-06-01 12:22', 'friends': [1, '2', b'3']}
+user = User(**external_data)
+print(user)
+#> User id=123 name='John Doe' signup_ts=datetime.datetime(2017, 6, 1, 12, 22) friends=[1, 2, 3]
+print(user.id)
+#> 123
+```

+## v2.12.3 (2025-10-17)
+
+[GitHub release](https://github.com/pydantic/pydantic/releases/tag/v2.12.3)
+
+### What's Changed
+
+This is the third 2.13 patch release, fixing issues related to the `FieldInfo` class, and reverting a change to the supported
+[*after* model validator](https://docs.pydantic.dev/latest/concepts/validators/#model-validators) function signatures.
+
+* Raise a warning when an invalid after model validator function signature is raised by [@Viicos](https://github.com/Viicos) in [#12414](https://github.com/pydantic/pydantic/pull/12414).
+  Starting in 2.12.0, using class methods for *after* model validators raised an error, but the error wasn't raised concistently. We decided
+  to emit a deprecation warning instead.
+* Add [`FieldInfo.asdict()`](https://docs.pydantic.dev/latest/api/fields/#pydantic.fields.FieldInfo.asdict) method, improve documentation around `FieldInfo` by [@Viicos](https://github.com/Viicos) in [#12411](https://github.com/pydantic/pydantic/pull/12411).
+  This also add back support for mutations on `FieldInfo` classes, that are reused as `Annotated` metadata. **However**, note that this is still
+  *not* a supported pattern. Instead, please refer to the [added example](https://docs.pydantic.dev/latest/examples/dynamic_models/) in the documentation.
+
+The [blog post](https://pydantic.dev/articles/pydantic-v2-12-release#changes) section on changes was also updated to document the changes related to `serialize_as_any`.
+
+#### Fixes
+
+* Release a new `pydantic-core` version, as a corrupted CPython 3.10 `manylinux2014_aarch64` wheel got uploaded ([pydantic-core#1843](https://github.com/pydantic/pydantic-core/pull/1843)).
+* Fix issue with recursive generic models with a parent model class by [@Viicos](https://github.com/Viicos) in [#12398](https://github.com/pydantic/pydantic/pull/12398)
+

+
+    When creating a Pydantic dataclass, it is possible to inherit from stdlib dataclasses, where
+    the Pydantic `Field()` function is used. To create this Pydantic dataclass, we first apply
+    the stdlib `@dataclass` decorator on it. During the construction of the stdlib dataclass,
+    the `kw_only` and `repr` field arguments need to be understood by the stdlib *during* the
+    dataclass construction. To do so, we temporarily patch the fields dictionary of the affected
+    bases.
+
+    For instance, with the following example:
+
+    ```python {test="skip" lint="skip"}
+    import dataclasses as stdlib_dc
+
+    import pydantic
+    import pydantic.dataclasses as pydantic_dc
+
+    @stdlib_dc.dataclass
+    class A:
+        a: int = pydantic.Field(repr=False)
+
+    # Notice that the `repr` attribute of the dataclass field is `True`:
+    A.__dataclass_fields__['a']
+    #> dataclass.Field(default=FieldInfo(repr=False), repr=True, ...)
+
+    @pydantic_dc.dataclass
+    class B(A):
+        b: int = pydantic.Field(repr=False)
+    ```
+
+    When passing `B` to the stdlib `@dataclass` decorator, it will look for fields in the parent classes
+    and reuse them directly. When this context manager is active, `A` will be temporarily patched to be
+    equivalent to:
+
+    ```python {test="skip" lint="skip"}
+    @stdlib_dc.dataclass
+    class A:
+        a: int = stdlib_dc.field(default=Field(repr=False), repr=False)
+    ```
+
+    !!! note
+        This is only applied to the bases of `cls`, and not `cls` itself. The reason is that the Pydantic
+        dataclass decorator "owns" `cls` (in the previous example, `B`). As such, we instead modify the fields
+        directly (in the previous example, we simply do `setattr(B, 'b', as_dataclass_field(pydantic_field))`).
+
+    !!! note
+        This approach is far from ideal, and can probably be the source of unwanted side effects/race conditions.
+        The previous implemented approach was mutating the `__annotations__` dict of `cls`, which is no longer a
+        safe operation in Python 3.14+, and resulted in unexpected behavior with field ordering anyway.
+    """

+            we might want to be smarter by only doing so when the type being pushed is defined

+    Whether to ignore, allow, or forbid extra data during model initialization. Defaults to `'ignore'`.
+
+    Three configuration values are available:
+
+    - `'ignore'`: Providing extra data is ignored (the default):
+      ```python
+      from pydantic import BaseModel, ConfigDict
+
+      class User(BaseModel):
+          model_config = ConfigDict(extra='ignore')  # (1)!
+

+
+      user = User(name='John Doe', age=20)  # (2)!
+      print(user)
+      #> name='John Doe'
+      ```
+
+        1. This is the default behaviour.
+        2. The `age` argument is ignored.
+
+    - `'forbid'`: Providing extra data is not permitted, and a [`ValidationError`][pydantic_core.ValidationError]
+      will be raised if this is the case:
+      ```python
+      from pydantic import BaseModel, ConfigDict, ValidationError
+
+
+      class Model(BaseModel):
+          x: int
+
+          model_config = ConfigDict(extra='forbid')
+
+
+      try:
+          Model(x=1, y='a')
+      except ValidationError as exc:
+          print(exc)
+          """

+          """
+      ```
+
+    - `'allow'`: Providing extra data is allowed and stored in the `__pydantic_extra__` dictionary attribute:
+      ```python
+      from pydantic import BaseModel, ConfigDict
+
+
+      class Model(BaseModel):
+          x: int
+
+          model_config = ConfigDict(extra='allow')
+
+
+      m = Model(x=1, y='a')
+      assert m.__pydantic_extra__ == {'y': 'a'}
+      ```
+      By default, no validation will be applied to these extra items, but you can set a type for the values by overriding
+      the type annotation for `__pydantic_extra__`:
+      ```python
+      from pydantic import BaseModel, ConfigDict, Field, ValidationError
+
+
+      class Model(BaseModel):
+          __pydantic_extra__: dict[str, int] = Field(init=False)  # (1)!
+
+          x: int
+
+          model_config = ConfigDict(extra='allow')
+
+
+      try:
+          Model(x=1, y='a')
+      except ValidationError as exc:
+          print(exc)
+          """
+          1 validation error for Model

+          """
+
+      m = Model(x=1, y='2')
+      assert m.x == 1
+      assert m.y == 2
+      assert m.model_dump() == {'x': 1, 'y': 2}
+      assert m.__pydantic_extra__ == {'y': 2}
+      ```
+
+        1. The `= Field(init=False)` does not have any effect at runtime, but prevents the `__pydantic_extra__` field from
+           being included as a parameter to the model's `__init__` method by type checkers.
+
+    As well as specifying an `extra` configuration value on the model, you can also provide it as an argument to the validation methods.
+    This will override any `extra` configuration value set on the model:
+    ```python
+    from pydantic import BaseModel, ConfigDict, ValidationError
+
+    class Model(BaseModel):
+        x: int
+        model_config = ConfigDict(extra="allow")

+
+    Note:
+        On V1, the inverse of this setting was called `allow_mutation`, and was `True` by default.
+    """
+
+    populate_by_name: bool
+    """
+    Whether an aliased field may be populated by its name as given by the model
+    attribute, as well as the alias. Defaults to `False`.
+
+    !!! warning
+        `populate_by_name` usage is not recommended in v2.11+ and will be deprecated in v3.
+        Instead, you should use the [`validate_by_name`][pydantic.config.ConfigDict.validate_by_name] configuration setting.
+
+        When `validate_by_name=True` and `validate_by_alias=True`, this is strictly equivalent to the
+        previous behavior of `populate_by_name=True`.
+
+        In v2.11, we also introduced a [`validate_by_alias`][pydantic.config.ConfigDict.validate_by_alias] setting that introduces more fine grained
+        control for validation behavior.
+
+        Here's how you might go about using the new settings to achieve the same behavior:
+
+        ```python
+        from pydantic import BaseModel, ConfigDict, Field
+
+        class Model(BaseModel):
+            model_config = ConfigDict(validate_by_name=True, validate_by_alias=True)
+
+            my_field: str = Field(alias='my_alias')  # (1)!
+
+        m = Model(my_alias='foo')  # (2)!
+        print(m)
+        #> my_field='foo'
+
+        m = Model(my_field='foo')  # (3)!
+        print(m)
+        #> my_field='foo'
+        ```
+
+        1. The field `'my_field'` has an alias `'my_alias'`.
+        2. The model is populated by the alias `'my_alias'`.
+        3. The model is populated by the attribute name `'my_field'`.
+    """
+
+    use_enum_values: bool
+    """
+    Whether to populate models with the `value` property of enums, rather than the raw enum.
+    This may be useful if you want to serialize `model.model_dump()` later. Defaults to `False`.
+
+    !!! note
+        If you have an `Optional[Enum]` value that you set a default for, you need to use `validate_default=True`
+        for said Field to ensure that the `use_enum_values` flag takes effect on the default, as extracting an
+        enum's value occurs during validation, not serialization.
+
+    ```python
+    from enum import Enum
+    from typing import Optional
+
+    from pydantic import BaseModel, ConfigDict, Field
+
+    class SomeEnum(Enum):
+        FOO = 'foo'
+        BAR = 'bar'
+        BAZ = 'baz'
+
+    class SomeModel(BaseModel):
+        model_config = ConfigDict(use_enum_values=True)
+
+        some_enum: SomeEnum
+        another_enum: Optional[SomeEnum] = Field(
+            default=SomeEnum.FOO, validate_default=True
+        )
+
+    model1 = SomeModel(some_enum=SomeEnum.BAR)
+    print(model1.model_dump())

+    model2 = SomeModel(some_enum=SomeEnum.BAR, another_enum=SomeEnum.BAZ)
+    print(model2.model_dump())
+    #> {'some_enum': 'bar', 'another_enum': 'baz'}
+    ```
+    """
+
+    validate_assignment: bool
+    """
+    Whether to validate the data when the model is changed. Defaults to `False`.
+
+    The default behavior of Pydantic is to validate the data when the model is created.
+
+    In case the user changes the data after the model is created, the model is _not_ revalidated.
+
+    ```python
+    from pydantic import BaseModel
+
+    class User(BaseModel):
+        name: str
+
+    user = User(name='John Doe')  # (1)!
+    print(user)
+    #> name='John Doe'
+    user.name = 123  # (1)!
+    print(user)
+    #> name=123
+    ```
+
+    1. The validation happens only when the model is created.
+    2. The validation does not happen when the data is changed.
+
+    In case you want to revalidate the model when the data is changed, you can use `validate_assignment=True`:
+
+    ```python
+    from pydantic import BaseModel, ValidationError
+
+    class User(BaseModel, validate_assignment=True):  # (1)!
+        name: str
+
+    user = User(name='John Doe')  # (2)!
+    print(user)
+    #> name='John Doe'
+    try:
+        user.name = 123  # (3)!
+    except ValidationError as e:
+        print(e)
+        '''

+        '''
+    ```
+
+    1. You can either use class keyword arguments, or `model_config` to set `validate_assignment=True`.
+    2. The validation happens when the model is created.
+    3. The validation _also_ happens when the data is changed.
+    """
+
+    arbitrary_types_allowed: bool

+
+    !!! warning
+        The `FieldInfo` class is meant to expose information about a field in a Pydantic model or dataclass.
+        `FieldInfo` instances shouldn't be instantiated directly, nor mutated.
+
+        If you need to derive a new model from another one and are willing to alter `FieldInfo` instances,
+        refer to this [dynamic model example](../examples/dynamic_models.md).
+
+    Attributes:
+        annotation: The type annotation of the field.
+        default: The default value of the field.
+        default_factory: A callable to generate the default value. The callable can either take 0 arguments
+            (in which case it is called as is) or a single argument containing the already validated data.
+        alias: The alias name of the field.
+        alias_priority: The priority of the field's alias.
+        validation_alias: The validation alias of the field.
+        serialization_alias: The serialization alias of the field.
+        title: The title of the field.
+        field_title_generator: A callable that takes a field name and returns title for it.
+        description: The description of the field.
+        examples: List of examples of the field.
+        exclude: Whether to exclude the field from the model serialization.
+        exclude_if: A callable that determines whether to exclude a field during serialization based on its value.
+        discriminator: Field name or Discriminator for discriminating the type in a tagged union.
+        deprecated: A deprecation message, an instance of `warnings.deprecated` or the `typing_extensions.deprecated` backport,
+            or a boolean. If `True`, a default deprecation message will be emitted when accessing the field.
+        json_schema_extra: A dict or callable to provide extra JSON schema properties.
+        frozen: Whether the field is frozen.
+        validate_default: Whether to validate the default value of the field.
+        repr: Whether to include the field in representation of the model.
+        init: Whether the field should be included in the constructor of the dataclass.
+        init_var: Whether the field should _only_ be included in the constructor of the dataclass, and not stored.
+        kw_only: Whether the field should be a keyword-only argument in the constructor of the dataclass.
+        metadata: The metadata list. Contains all the data that isn't expressed as direct `FieldInfo` attributes, including:
+
+            * Type-specific constraints, such as `gt` or `min_length` (these are converted to metadata classes such as `annotated_types.Gt`).

+
+    Create a field for objects that can be configured.
+
+    Used to provide extra information about a field, either for the model schema or complex validation. Some arguments
+    apply only to number fields (`int`, `float`, `Decimal`) and some apply only to `str`.
+
+    Note:
+        - Any `_Unset` objects will be replaced by the corresponding value defined in the `_DefaultValues` dictionary. If a key for the `_Unset` object is not found in the `_DefaultValues` dictionary, it will default to `None`
+
+    Args:
+        default: Default value if the field is not set.
+        default_factory: A callable to generate the default value. The callable can either take 0 arguments
+            (in which case it is called as is) or a single argument containing the already validated data.
+        alias: The name to use for the attribute when validating or serializing by alias.
+            This is often used for things like converting between snake and camel case.
+        alias_priority: Priority of the alias. This affects whether an alias generator is used.
+        validation_alias: Like `alias`, but only affects validation, not serialization.
+        serialization_alias: Like `alias`, but only affects serialization, not validation.
+        title: Human-readable title.
+        field_title_generator: A callable that takes a field name and returns title for it.
+        description: Human-readable description.
+        examples: Example values for this field.
+        exclude: Whether to exclude the field from the model serialization.
+        exclude_if: A callable that determines whether to exclude a field during serialization based on its value.

+        union_mode: The strategy to apply when validating a union. Can be `smart` (the default), or `left_to_right`.
+            See [Union Mode](../concepts/unions.md#union-modes) for details.
+        fail_fast: If `True`, validation will stop on the first error. If `False`, all validation errors will be collected.

+    !!! warning "Overriding with `computed_field`"
+        You can't override a field from a parent class with a `computed_field` in the child class.
+        `mypy` complains about this behavior if allowed, and `dataclasses` doesn't allow this pattern either.
+        See the example below:
+
+    ```python

+        Field 'a' of class 'Child' overrides symbol of same name in a parent class. This override with a computed_field is incompatible.
+        '''
+    ```
+
+    Private properties decorated with `@computed_field` have `repr=False` by default.

+
+    !!! note
+        Before v2.9, `PlainValidator` wasn't always compatible with JSON Schema generation for `mode='validation'`.
+        You can now use the `json_schema_input_type` argument to specify the input type of the function
+        to be used in the JSON schema when `mode='validation'` (the default). See the example below for more details.
+
+    Attributes:
+        func: The validator function.
+        json_schema_input_type: The input type used to generate the appropriate
+            JSON Schema (in validation mode). The actual input type is `Any`.
+
+    Example:
+        ```python
+        from typing import Annotated, Union
+
+        from pydantic import BaseModel, PlainValidator
+

+
+        1. In this example, we've specified the `json_schema_input_type` as `Union[str, int]` which indicates to the JSON schema

+The `json_schema` module contains classes and functions to allow the way [JSON Schema](https://json-schema.org/)
+is generated to be customized.
+
+In general you shouldn't need to use this module directly; instead, you can use
+[`BaseModel.model_json_schema`][pydantic.BaseModel.model_json_schema] and
+[`TypeAdapter.json_schema`][pydantic.TypeAdapter.json_schema].

+
+    A class for generating JSON schemas.
+
+    This class generates JSON schemas based on configured parameters. The default schema dialect
+    is [https://json-schema.org/draft/2020-12/schema](https://json-schema.org/draft/2020-12/schema).
+    The class uses `by_alias` to configure how fields with
+    multiple names are handled and `ref_template` to format reference names.
+
+    Attributes:
+        schema_dialect: The JSON schema dialect used to generate the schema. See
+            [Declaring a Dialect](https://json-schema.org/understanding-json-schema/reference/schema.html#id4)
+            in the JSON Schema documentation for more information about dialects.
+        ignored_warning_kinds: Warnings to ignore when generating the schema. `self.render_warning_message` will
+            do nothing if its argument `kind` is in `ignored_warning_kinds`;
+            this value can be modified on subclasses to easily control which warnings are emitted.
+        by_alias: Whether to use field aliases when generating the schema.
+        ref_template: The format string used when generating reference names.
+        core_to_json_refs: A mapping of core refs to JSON refs.
+        core_to_defs_refs: A mapping of core refs to definition refs.
+        defs_to_core_refs: A mapping of definition refs to core refs.
+        json_to_defs_refs: A mapping of JSON refs to definition refs.
+        definitions: Definitions in the schema.
+
+    Args:
+        by_alias: Whether to use field aliases in the generated schemas.
+        ref_template: The format string to use when generating reference names.
+        union_format: The format to use when combining schemas from unions together. Can be one of:
+
+            - `'any_of'`: Use the [`anyOf`](https://json-schema.org/understanding-json-schema/reference/combining#anyOf)
+              keyword to combine schemas (the default).
+            - `'primitive_type_array'`: Use the [`type`](https://json-schema.org/understanding-json-schema/reference/type)
+              keyword as an array of strings, containing each type of the combination. If any of the schemas is not a primitive
+              type (`string`, `boolean`, `null`, `integer` or `number`) or contains constraints/metadata, falls back to
+              `any_of`.

+    !!! warning "Underscores in Hostnames"
+        In Pydantic, underscores are allowed in all parts of a domain except the TLD.
+        Technically this might be wrong - in theory the hostname cannot have underscores, but subdomains can.
+
+        To explain this; consider the following two cases:
+
+        - `exam_ple.co.uk`: the hostname is `exam_ple`, which should not be allowed since it contains an underscore.
+        - `foo_bar.example.com` the hostname is `example`, which should be allowed since the underscore is in the subdomain.
+
+        Without having an exhaustive list of TLDs, it would be impossible to differentiate between these two. Therefore
+        underscores are allowed, but you can always do further validation in a validator if desired.
+
+        Also, Chrome, Firefox, and Safari all currently accept `http://exam_ple.com` as a URL, so we're in good
+        (or at least big) company.

+        [`TypeAdapter`](../concepts/type_adapter.md)
+
+    Type adapters provide a flexible way to perform validation and serialization based on a Python type.
+
+    A `TypeAdapter` instance exposes some of the functionality from `BaseModel` instance methods
+    for types that do not have such methods (such as dataclasses, primitive types, and more).
+
+    **Note:** `TypeAdapter` instances are not types, and cannot be used as type annotations for fields.
+
+    Args:
+        type: The type associated with the `TypeAdapter`.
+        config: Configuration for the `TypeAdapter`, should be a dictionary conforming to
+            [`ConfigDict`][pydantic.config.ConfigDict].
+
+            !!! note
+                You cannot provide a configuration when instantiating a `TypeAdapter` if the type you're using
+                has its own config that cannot be overridden (ex: `BaseModel`, `TypedDict`, and `dataclass`). A
+                [`type-adapter-config-unused`](../errors/usage_errors.md#type-adapter-config-unused) error will
+                be raised in this case.
+        _parent_depth: Depth at which to search for the [parent frame][frame-objects]. This frame is used when
+            resolving forward annotations during schema building, by looking for the globals and locals of this
+            frame. Defaults to 2, which will result in the frame where the `TypeAdapter` was instantiated.
+
+            !!! note
+                This parameter is named with an underscore to suggest its private nature and discourage use.
+                It may be deprecated in a minor version, so we only recommend using it if you're comfortable
+                with potential change in behavior/support. It's default value is 2 because internally,
+                the `TypeAdapter` class makes another call to fetch the frame.
+        module: The module that passes to plugin if provided.
+
+    Attributes:
+        core_schema: The core schema for the type.
+        validator: The schema validator for the type.
+        serializer: The schema serializer for the type.
+        pydantic_complete: Whether the core schema for the type is successfully built.
+
+    ??? tip "Compatibility with `mypy`"
+        Depending on the type used, `mypy` might raise an error when instantiating a `TypeAdapter`. As a workaround, you can explicitly
+        annotate your variable:
+
+        ```py
+        from typing import Union
+
+        from pydantic import TypeAdapter
+
+        ta: TypeAdapter[Union[str, int]] = TypeAdapter(Union[str, int])  # type: ignore[arg-type]
+        ```
+
+    ??? info "Namespace management nuances and implementation details"
+
+        Here, we collect some notes on namespace management, and subtle differences from `BaseModel`:
+
+        `BaseModel` uses its own `__module__` to find out where it was defined
+        and then looks for symbols to resolve forward references in those globals.
+        On the other hand, `TypeAdapter` can be initialized with arbitrary objects,
+        which may not be types and thus do not have a `__module__` available.
+        So instead we look at the globals in our parent stack frame.
+
+        It is expected that the `ns_resolver` passed to this function will have the correct
+        namespace for the type we're adapting. See the source code for `TypeAdapter.__init__`
+        and `TypeAdapter.rebuild` for various ways to construct this namespace.
+
+        This works for the case where this function is called in a module that
+        has the target of forward references in its scope, but
+        does not always work for more complex cases.
+
+        For example, take the following:
+
+        ```python {title="a.py"}
+        IntList = list[int]
+        OuterDict = dict[str, 'IntList']
+        ```
+
+        ```python {test="skip" title="b.py"}
+        from a import OuterDict
+
+        from pydantic import TypeAdapter
+
+        IntList = int  # replaces the symbol the forward reference is looking for
+        v = TypeAdapter(OuterDict)
+        v({'x': 1})  # should fail but doesn't
+        ```
+
+        If `OuterDict` were a `BaseModel`, this would work because it would resolve
+        the forward reference within the `a.py` namespace.
+        But `TypeAdapter(OuterDict)` can't determine what module `OuterDict` came from.
+
+        In other words, the assumption that _all_ forward references exist in the
+        module we are being called from is not technically always true.
+        Although most of the time it is and it works fine for recursive models and such,
+        `BaseModel`'s behavior isn't perfect either and _can_ break in similar ways,
+        so there is no right or wrong between the two.
+
+        But at the very least this behavior is _subtly_ different from `BaseModel`'s.

+
+    You may either directly parametrize `Secret` with a type, or subclass from `Secret` with a parametrized type. The benefit of subclassing
+    is that you can define a custom `_display` method, which will be used for `repr()` and `str()` methods. The examples below demonstrate both
+    ways of using `Secret` to create a new secret type.
+
+    1. Directly parametrizing `Secret` with a type:
+
+    ```python
+    from pydantic import BaseModel, Secret
+
+    SecretBool = Secret[bool]
+
+    class Model(BaseModel):
+        secret_bool: SecretBool
+
+    m = Model(secret_bool=True)
+    print(m.model_dump())
+    #> {'secret_bool': Secret('**********')}
+
+    print(m.model_dump_json())
+    #> {"secret_bool":"**********"}
+
+    print(m.secret_bool.get_secret_value())
+    #> True
+    ```
+
+    2. Subclassing from parametrized `Secret`:
+
+    ```python
+    from datetime import date
+
+    from pydantic import BaseModel, Secret
+
+    class SecretDate(Secret[date]):
+        def _display(self) -> str:
+            return '****/**/**'
+
+    class Model(BaseModel):
+        secret_date: SecretDate
+
+    m = Model(secret_date=date(2022, 1, 1))
+    print(m.model_dump())
+    #> {'secret_date': SecretDate('****/**/**')}
+
+    print(m.model_dump_json())
+    #> {"secret_date":"****/**/**"}
+
+    print(m.secret_date.get_secret_value())
+    #> 2022-01-01
+    ```
+
+    The value returned by the `_display` method will be used for `repr()` and `str()`.
+
+    You can enforce constraints on the underlying type through annotations:
+    For example:
+
+    ```python
+    from typing import Annotated
+
+    from pydantic import BaseModel, Field, Secret, ValidationError
+
+    SecretPosInt = Secret[Annotated[int, Field(gt=0, strict=True)]]
+
+    class Model(BaseModel):
+        sensitive_int: SecretPosInt
+
+    m = Model(sensitive_int=42)
+    print(m.model_dump())
+    #> {'sensitive_int': Secret('**********')}
+
+    try:
+        m = Model(sensitive_int=-42)  # (1)!
+    except ValidationError as exc_info:

+"""
+Register Hypothesis strategies for Pydantic custom types.
+
+This enables fully-automatic generation of test data for most Pydantic classes.
+
+Note that this module has *no* runtime impact on Pydantic itself; instead it
+is registered as a setuptools entry point and Hypothesis will import it if
+Pydantic is installed.  See also:
+
+https://hypothesis.readthedocs.io/en/latest/strategies.html#registering-strategies-via-setuptools-entry-points
+https://hypothesis.readthedocs.io/en/latest/data.html#hypothesis.strategies.register_type_strategy
+https://hypothesis.readthedocs.io/en/latest/strategies.html#interaction-with-pytest-cov
+https://docs.pydantic.dev/usage/types/#pydantic-types
+
+Note that because our motivation is to *improve user experience*, the strategies
+are always sound (never generate invalid data) but sacrifice completeness for
+maintainability (ie may be unable to generate some tricky but valid data).
+
+Finally, this module makes liberal use of `# type: ignore[<code>]` pragmas.
+This is because Hypothesis annotates `register_type_strategy()` with
+`(T, SearchStrategy[T])`, but in most cases we register e.g. `ConstrainedInt`
+to generate instances of the builtin `int` type which match the constraints.

+"""
+The main purpose is to enhance stdlib dataclasses by adding validation
+A pydantic dataclass can be generated from scratch or from a stdlib one.
+
+Behind the scene, a pydantic dataclass is just like a regular one on which we attach
+a `BaseModel` and magic methods to trigger the validation of the data.
+`__init__` and `__post_init__` are hence overridden and have extra logic to be
+able to validate input data.
+
+When a pydantic dataclass is generated from scratch, it's just a plain dataclass
+with validation triggered at initialization
+
+The tricky part if for stdlib dataclasses that are converted after into pydantic ones e.g.
+
+```py
+@dataclasses.dataclass
+class M:
+    x: int
+
+ValidatedM = pydantic.dataclasses.dataclass(M)
+```
+
+We indeed still want to support equality, hashing, repr, ... as if it was the stdlib one!
+
+```py
+assert isinstance(ValidatedM(x=1), M)
+assert ValidatedM(x=1) == M(x=1)
+```
+
+This means we **don't want to create a new dataclass that inherits from it**
+The trick is to create a wrapper around `M` that will act as a proxy to trigger
+validation without altering default `M` behaviour.

+
+This package provides the core functionality for [pydantic](https://docs.pydantic.dev) validation and serialization.
+
+Pydantic-core is currently around 17x faster than pydantic V1.
+See [`tests/benchmarks/`](./tests/benchmarks/) for details.
+
+## Example of direct usage
+
+_NOTE: You should not need to use pydantic-core directly; instead, use pydantic, which in turn uses pydantic-core._
+
+```py
+from pydantic_core import SchemaValidator, ValidationError
+
+
+v = SchemaValidator(
+    {
+        'type': 'typed-dict',
+        'fields': {
+            'name': {
+                'type': 'typed-dict-field',
+                'schema': {
+                    'type': 'str',
+                },
+            },
+            'age': {
+                'type': 'typed-dict-field',
+                'schema': {
+                    'type': 'int',
+                    'ge': 18,
+                },
+            },
+            'is_developer': {
+                'type': 'typed-dict-field',
+                'schema': {
+                    'type': 'default',
+                    'schema': {'type': 'bool'},
+                    'default': True,
+                },
+            },
+        },
+    }
+)
+
+r1 = v.validate_python({'name': 'Samuel', 'age': 35})
+assert r1 == {'name': 'Samuel', 'age': 35, 'is_developer': True}
+
+# pydantic-core can also validate JSON directly
+r2 = v.validate_json('{"name": "Samuel", "age": 35}')
+assert r1 == r2
+
+try:
+    v.validate_python({'name': 'Samuel', 'age': 11})
+except ValidationError as e:
+    print(e)
+    """
+    1 validation error for model
+    age
+      Input should be greater than or equal to 18
+      [type=greater_than_equal, context={ge: 18}, input_value=11, input_type=int]
+    """
+```
+
+## Getting Started
+
+### Prerequisites
+
+You'll need:
+1. **[Rust](https://rustup.rs/)** - Rust stable (or nightly for coverage)
+2. **[uv](https://docs.astral.sh/uv/getting-started/installation/)** - Fast Python package manager (will install Python 3.9+ automatically)
+3. **[git](https://git-scm.com/)** - For version control
+4. **[make](https://www.gnu.org/software/make/)** - For running development commands (or use `nmake` on Windows)
+
+### Quick Start
+
+```bash
+# Clone the repository (or from your fork)
+git clone git@github.com:pydantic/pydantic-core.git
+cd pydantic-core
+
+# Install all dependencies using uv, setup pre-commit hooks, and build the development version
+make install
+```
+
+Verify your installation by running:
+
+```bash
+make
+```
+
+This runs a full development cycle: formatting, building, linting, and testing
+
+### Development Commands
+
+Run `make help` to see all available commands, or use these common ones:
+
+```bash
+make build-dev    # to build the package during development
+make build-prod   # to perform an optimised build for benchmarking
+make test         # to run the tests
+make testcov      # to run the tests and generate a coverage report
+make lint         # to run the linter
+make format       # to format python and rust code
+make all          # to run to run build-dev + format + lint + test
+```
+
+### Useful Resources
+
+* [`python/pydantic_core/_pydantic_core.pyi`](./python/pydantic_core/_pydantic_core.pyi) - Python API types
+* [`python/pydantic_core/core_schema.py`](./python/pydantic_core/core_schema.py) - Core schema definitions
+* [`tests/`](./tests) - Comprehensive usage examples
+
+## Profiling
+
+It's possible to profile the code using the [`flamegraph` utility from `flamegraph-rs`](https://github.com/flamegraph-rs/flamegraph). (Tested on Linux.) You can install this with `cargo install flamegraph`.
+
+Run `make build-profiling` to install a release build with debugging symbols included (needed for profiling).
+
+Once that is built, you can profile pytest benchmarks with (e.g.):
+
+```bash
+flamegraph -- pytest tests/benchmarks/test_micro_benchmarks.py -k test_list_of_ints_core_py --benchmark-enable
+```
+The `flamegraph` command will produce an interactive SVG at `flamegraph.svg`.
+
+## Releasing
+
+1. Bump package version locally. Do not just edit `Cargo.toml` on Github, you need both `Cargo.toml` and `Cargo.lock` to be updated.
+2. Make a PR for the version bump and merge it.
+3. Go to https://github.com/pydantic/pydantic-core/releases and click "Draft a new release"
+4. In the "Choose a tag" dropdown enter the new tag `v<the.new.version>` and select "Create new tag on publish" when the option appears.
+5. Enter the release title in the form "v<the.new.version> <YYYY-MM-DD>"
+6. Click Generate release notes button
+7. Click Publish release
+8. Go to https://github.com/pydantic/pydantic-core/actions and ensure that all build for release are done successfully.
+9. Go to https://pypi.org/project/pydantic-core/ and ensure that the latest release is published.
+10. Done 🎉

+
+      "Source" form shall mean the preferred form for making modifications,

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+Requests allows you to send HTTP/1.1 requests extremely easily. There’s no need to manually add query strings to your URLs, or to form-encode your `PUT` & `POST` data — but nowadays, just use the `json` method!
+
+Requests is one of the most downloaded Python packages today, pulling in around `30M downloads / week`— according to GitHub, Requests is currently [depended upon](https://github.com/psf/requests/network/dependents?package_id=UGFja2FnZS01NzA4OTExNg%3D%3D) by `1,000,000+` repositories. You may certainly put your trust in this code.

+
+## Cloning the repository
+
+When cloning the Requests repository, you may need to add the `-c
+fetch.fsck.badTimezone=ignore` flag to avoid an error about a bad commit (see
+[this issue](https://github.com/psf/requests/issues/2690) for more background):
+
+```shell
+git clone -c fetch.fsck.badTimezone=ignore https://github.com/psf/requests.git
+```
+
+You can also apply this setting to your global Git config:
+
+```shell
+git config --global fetch.fsck.badTimezone ignore
+```

+Requests HTTP Library
+~~~~~~~~~~~~~~~~~~~~~
+
+Requests is an HTTP library, written in Python, for human beings.
+Basic GET usage:
+
+   >>> import requests
+   >>> r = requests.get('https://www.python.org')
+   >>> r.status_code
+   200
+   >>> b'Python is a programming language' in r.content
+   True
+
+... or POST:
+
+   >>> payload = dict(key1='value1', key2='value2')
+   >>> r = requests.post('https://httpbin.org/post', data=payload)
+   >>> print(r.text)
+   {
+     ...
+     "form": {
+       "key1": "value1",
+       "key2": "value2"
+     },
+     ...
+   }
+
+The other HTTP methods are supported - see `requests.api`. Full documentation
+is at <https://requests.readthedocs.io>.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the

+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+=================================================================
+sniffio: Sniff out which async library your code is running under
+=================================================================
+
+You're writing a library. You've decided to be ambitious, and support
+multiple async I/O packages, like `Trio
+<https://trio.readthedocs.io>`__, and `asyncio
+<https://docs.python.org/3/library/asyncio.html>`__, and ... You've
+written a bunch of clever code to handle all the differences. But...
+how do you know *which* piece of clever code to run?
+
+This is a tiny package whose only purpose is to let you detect which
+async library your code is running under.
+
+* Documentation: https://sniffio.readthedocs.io
+
+* Bug tracker and source code: https://github.com/python-trio/sniffio
+
+* License: MIT or Apache License 2.0, your choice
+
+* Contributor guide: https://trio.readthedocs.io/en/latest/contributing.html
+
+* Code of conduct: Contributors are requested to follow our `code of
+  conduct
+  <https://trio.readthedocs.io/en/latest/code-of-conduct.html>`_
+  in all project spaces.
+
+This library is maintained by the Trio project, as a service to the
+async Python community as a whole.

+and is an abbreviation for "I love you so much" in Spanish (*te quiero demasiado*).
+
+Instantly make your loops show a smart progress meter - just wrap any
+iterable with ``tqdm(iterable)``, and you're done!
+
+.. code:: python
+
+    from tqdm import tqdm
+    for i in tqdm(range(10000)):
+        ...
+
+``76%|████████████████████████        | 7568/10000 [00:33<00:10, 229.00it/s]``
+
+``trange(N)`` can be also used as a convenient shortcut for
+``tqdm(range(N))``.
+

+
+It can also be executed as a module with pipes:
+
+.. code:: sh
+
+    $ seq 9999999 | tqdm --bytes | wc -l
+    75.2MB [00:00, 217MB/s]
+    9999999
+
+    $ tar -zcf - docs/ | tqdm --bytes --total `du -sb docs/ | cut -f1` \
+        > backup.tgz
+     32%|██████████▍                      | 8.89G/27.9G [00:42<01:31, 223MB/s]
+
+Overhead is low -- about 60ns per iteration (80ns with ``tqdm.gui``), and is
+unit tested against performance regression.
+By comparison, the well-established
+`ProgressBar <https://github.com/niltonvolpato/python-progressbar>`__ has
+an 800ns/iter overhead.
+
+In addition to its low overhead, ``tqdm`` uses smart algorithms to predict
+the remaining time and to skip unnecessary iteration displays, which allows
+for a negligible overhead in most cases.
+
+``tqdm`` works on any platform
+(Linux, Windows, Mac, FreeBSD, NetBSD, Solaris/SunOS),
+in any console or in a GUI, and is also friendly with IPython/Jupyter notebooks.
+
+``tqdm`` does not require any dependencies (not even ``curses``!), just
+Python and an environment supporting ``carriage return \r`` and
+``line feed \n`` control characters.

+---------
+
+The list of all changes is available either on GitHub's Releases:
+|GitHub-Status|, on the
+`wiki <https://github.com/tqdm/tqdm/wiki/Releases>`__, or on the
+`website <https://tqdm.github.io/releases>`__.
+
+
+Usage
+-----
+
+``tqdm`` is very versatile and can be used in a number of ways.
+The three main ones are given below.
+
+Iterable-based
+~~~~~~~~~~~~~~
+
+Wrap ``tqdm()`` around any iterable:
+
+.. code:: python
+
+    from tqdm import tqdm
+    from time import sleep
+
+    text = ""
+    for char in tqdm(["a", "b", "c", "d"]):
+        sleep(0.25)
+        text = text + char
+
+``trange(i)`` is a special optimised instance of ``tqdm(range(i))``:
+
+.. code:: python
+
+    from tqdm import trange
+
+    for i in trange(100):
+        sleep(0.01)
+
+Instantiation outside of the loop allows for manual control over ``tqdm()``:
+
+.. code:: python
+
+    pbar = tqdm(["a", "b", "c", "d"])
+    for char in pbar:
+        sleep(0.25)
+        pbar.set_description("Processing %s" % char)
+
+Manual
+~~~~~~
+
+Manual control of ``tqdm()`` updates using a ``with`` statement:
+
+.. code:: python
+
+    with tqdm(total=100) as pbar:
+        for i in range(10):
+            sleep(0.1)
+            pbar.update(10)
+
+If the optional variable ``total`` (or an iterable with ``len()``) is
+provided, predictive stats are displayed.
+
+``with`` is also optional (you can just assign ``tqdm()`` to a variable,
+but in this case don't forget to ``del`` or ``close()`` at the end:
+
+.. code:: python
+
+    pbar = tqdm(total=100)
+    for i in range(10):
+        sleep(0.1)
+        pbar.update(10)
+    pbar.close()
+
+Module
+~~~~~~
+
+Perhaps the most wonderful use of ``tqdm`` is in a script or on the command
+line. Simply inserting ``tqdm`` (or ``python -m tqdm``) between pipes will pass
+through all ``stdin`` to ``stdout`` while printing progress to ``stderr``.
+
+The example below demonstrate counting the number of lines in all Python files
+in the current directory, with timing information included.
+
+.. code:: sh
+
+    $ time find . -name '*.py' -type f -exec cat \{} \; | wc -l
+    857365
+
+    real    0m3.458s
+    user    0m0.274s
+    sys     0m3.325s
+
+    $ time find . -name '*.py' -type f -exec cat \{} \; | tqdm | wc -l
+    857366it [00:03, 246471.31it/s]
+    857365
+
+    real    0m3.585s
+    user    0m0.862s
+    sys     0m3.358s
+
+Note that the usual arguments for ``tqdm`` can also be specified.
+
+.. code:: sh
+
+    $ find . -name '*.py' -type f -exec cat \{} \; |
+        tqdm --unit loc --unit_scale --total 857366 >> /dev/null
+    100%|█████████████████████████████████| 857K/857K [00:04<00:00, 246Kloc/s]
+
+Backing up a large directory?
+
+.. code:: sh
+
+    $ tar -zcf - docs/ | tqdm --bytes --total `du -sb docs/ | cut -f1` \
+      > backup.tgz

+
+This can be beautified further:
+
+.. code:: sh
+
+    $ BYTES=$(du -sb docs/ | cut -f1)
+    $ tar -cf - docs/ \
+      | tqdm --bytes --total "$BYTES" --desc Processing | gzip \

+
+Or done on a file level using 7-zip:
+
+.. code:: sh
+
+    $ 7z a -bd -r backup.7z docs/ | grep Compressing \
+      | tqdm --total $(find docs/ -type f | wc -l) --unit files \

+
+Pre-existing CLI programs already outputting basic progress information will
+benefit from ``tqdm``'s ``--update`` and ``--update_to`` flags:
+
+.. code:: sh
+
+    $ seq 3 0.1 5 | tqdm --total 5 --update_to --null
+    100%|████████████████████████████████████| 5.0/5 [00:00<00:00, 9673.21it/s]

+
+FAQ and Known Issues
+--------------------
+
+|GitHub-Issues|
+
+The most common issues relate to excessive output on multiple lines, instead
+of a neat one-line progress bar.
+
+- Consoles in general: require support for carriage return (``CR``, ``\r``).
+
+  * Some cloud logging consoles which don't support ``\r`` properly
+    (`cloudwatch <https://github.com/tqdm/tqdm/issues/966>`__,
+    `K8s <https://github.com/tqdm/tqdm/issues/1319>`__) may benefit from
+    ``export TQDM_POSITION=-1``.
+
+- Nested progress bars:
+
+  * Consoles in general: require support for moving cursors up to the
+    previous line. For example,
+    `IDLE <https://github.com/tqdm/tqdm/issues/191#issuecomment-230168030>`__,
+    `ConEmu <https://github.com/tqdm/tqdm/issues/254>`__ and
+    `PyCharm <https://github.com/tqdm/tqdm/issues/203>`__ (also
+    `here <https://github.com/tqdm/tqdm/issues/208>`__,
+    `here <https://github.com/tqdm/tqdm/issues/307>`__, and
+    `here <https://github.com/tqdm/tqdm/issues/454#issuecomment-335416815>`__)
+    lack full support.
+  * Windows: additionally may require the Python module ``colorama``
+    to ensure nested bars stay within their respective lines.
+
+- Unicode:
+
+  * Environments which report that they support unicode will have solid smooth
+    progressbars. The fallback is an ``ascii``-only bar.
+  * Windows consoles often only partially support unicode and thus
+    `often require explicit ascii=True <https://github.com/tqdm/tqdm/issues/454#issuecomment-335416815>`__
+    (also `here <https://github.com/tqdm/tqdm/issues/499>`__). This is due to
+    either normal-width unicode characters being incorrectly displayed as
+    "wide", or some unicode characters not rendering.
+
+- Wrapping generators:
+
+  * Generator wrapper functions tend to hide the length of iterables.
+    ``tqdm`` does not.
+  * Replace ``tqdm(enumerate(...))`` with ``enumerate(tqdm(...))`` or
+    ``tqdm(enumerate(x), total=len(x), ...)``.
+    The same applies to ``numpy.ndenumerate``.
+  * Replace ``tqdm(zip(a, b))`` with ``zip(tqdm(a), b)`` or even
+    ``zip(tqdm(a), tqdm(b))``.
+  * The same applies to ``itertools``.
+  * Some useful convenience functions can be found under ``tqdm.contrib``.
+
+- `No intermediate output in docker-compose <https://github.com/tqdm/tqdm/issues/771>`__:
+  use ``docker-compose run`` instead of ``docker-compose up`` and ``tty: true``.
+
+- Overriding defaults via environment variables:
+  e.g. in CI/cloud jobs, ``export TQDM_MININTERVAL=5`` to avoid log spam.
+  This override logic is handled by the ``tqdm.utils.envwrap`` decorator
+  (useful independent of ``tqdm``).
+
+If you come across any other difficulties, browse and file |GitHub-Issues|.

+
+Parameters
+~~~~~~~~~~
+
+* iterable  : iterable, optional  
+    Iterable to decorate with a progressbar.
+    Leave blank to manually manage the updates.
+* desc  : str, optional  
+    Prefix for the progressbar.
+* total  : int or float, optional  
+    The number of expected iterations. If unspecified,
+    len(iterable) is used if possible. If float("inf") or as a last
+    resort, only basic progress statistics are displayed
+    (no ETA, no progressbar).
+    If ``gui`` is True and this parameter needs subsequent updating,
+    specify an initial arbitrary large positive number,
+    e.g. 9e9.
+* leave  : bool, optional  
+    If [default: True], keeps all traces of the progressbar
+    upon termination of iteration.
+    If ``None``, will leave only if ``position`` is ``0``.
+* file  : ``io.TextIOWrapper`` or ``io.StringIO``, optional  
+    Specifies where to output the progress messages
+    (default: sys.stderr). Uses ``file.write(str)`` and ``file.flush()``
+    methods.  For encoding, see ``write_bytes``.
+* ncols  : int, optional  
+    The width of the entire output message. If specified,
+    dynamically resizes the progressbar to stay within this bound.
+    If unspecified, attempts to use environment width. The
+    fallback is a meter width of 10 and no limit for the counter and
+    statistics. If 0, will not print any meter (only stats).
+* mininterval  : float, optional  
+    Minimum progress display update interval [default: 0.1] seconds.
+* maxinterval  : float, optional  
+    Maximum progress display update interval [default: 10] seconds.
+    Automatically adjusts ``miniters`` to correspond to ``mininterval``
+    after long display update lag. Only works if ``dynamic_miniters``
+    or monitor thread is enabled.
+* miniters  : int or float, optional  
+    Minimum progress display update interval, in iterations.
+    If 0 and ``dynamic_miniters``, will automatically adjust to equal
+    ``mininterval`` (more CPU efficient, good for tight loops).
+    If > 0, will skip display of specified number of iterations.
+    Tweak this and ``mininterval`` to get very efficient loops.
+    If your progress is erratic with both fast and slow iterations
+    (network, skipping items, etc) you should set miniters=1.
+* ascii  : bool or str, optional  
+    If unspecified or False, use unicode (smooth blocks) to fill
+    the meter. The fallback is to use ASCII characters " 123456789#".
+* disable  : bool, optional  
+    Whether to disable the entire progressbar wrapper
+    [default: False]. If set to None, disable on non-TTY.
+* unit  : str, optional  
+    String that will be used to define the unit of each iteration
+    [default: it].
+* unit_scale  : bool or int or float, optional  
+    If 1 or True, the number of iterations will be reduced/scaled
+    automatically and a metric prefix following the
+    International System of Units standard will be added
+    (kilo, mega, etc.) [default: False]. If any other non-zero
+    number, will scale ``total`` and ``n``.
+* dynamic_ncols  : bool, optional  
+    If set, constantly alters ``ncols`` and ``nrows`` to the
+    environment (allowing for window resizes) [default: False].
+* smoothing  : float, optional  
+    Exponential moving average smoothing factor for speed estimates
+    (ignored in GUI mode). Ranges from 0 (average speed) to 1
+    (current/instantaneous speed) [default: 0.3].
+* bar_format  : str, optional  
+    Specify a custom bar string formatting. May impact performance.
+    [default: '{l_bar}{bar}{r_bar}'], where
+    l_bar='{desc}: {percentage:3.0f}%|' and
+    r_bar='| {n_fmt}/{total_fmt} [{elapsed}<{remaining}, '
+    '{rate_fmt}{postfix}]'
+    Possible vars: l_bar, bar, r_bar, n, n_fmt, total, total_fmt,
+    percentage, elapsed, elapsed_s, ncols, nrows, desc, unit,
+    rate, rate_fmt, rate_noinv, rate_noinv_fmt,
+    rate_inv, rate_inv_fmt, postfix, unit_divisor,
+    remaining, remaining_s, eta.
+    Note that a trailing ": " is automatically removed after {desc}
+    if the latter is empty.
+* initial  : int or float, optional  
+    The initial counter value. Useful when restarting a progress
+    bar [default: 0]. If using float, consider specifying ``{n:.3f}``
+    or similar in ``bar_format``, or specifying ``unit_scale``.
+* position  : int, optional  
+    Specify the line offset to print this bar (starting from 0)
+    Automatic if unspecified.
+    Useful to manage multiple bars at once (eg, from threads).
+* postfix  : dict or ``*``, optional  
+    Specify additional stats to display at the end of the bar.
+    Calls ``set_postfix(**postfix)`` if possible (dict).
+* unit_divisor  : float, optional  
+    [default: 1000], ignored unless ``unit_scale`` is True.
+* write_bytes  : bool, optional  
+    Whether to write bytes. If (default: False) will write unicode.
+* lock_args  : tuple, optional  
+    Passed to ``refresh`` for intermediate output
+    (initialisation, iterating, and updating).
+* nrows  : int, optional  
+    The screen height. If specified, hides nested bars outside this
+    bound. If unspecified, attempts to use environment height.
+    The fallback is 20.
+* colour  : str, optional  
+    Bar colour (e.g. 'green', '#00ff00').
+* delay  : float, optional  
+    Don't display until [default: 0] seconds have elapsed.
+
+Extra CLI Options
+~~~~~~~~~~~~~~~~~
+
+* delim  : chr, optional  
+    Delimiting character [default: '\n']. Use '\0' for null.
+    N.B.: on Windows systems, Python converts '\n' to '\r\n'.
+* buf_size  : int, optional  
+    String buffer size in bytes [default: 256]
+    used when ``delim`` is specified.
+* bytes  : bool, optional  
+    If true, will count bytes, ignore ``delim``, and default
+    ``unit_scale`` to True, ``unit_divisor`` to 1024, and ``unit`` to 'B'.
+* tee  : bool, optional  
+    If true, passes ``stdin`` to both ``stderr`` and ``stdout``.
+* update  : bool, optional  
+    If true, will treat input as newly elapsed iterations,
+    i.e. numbers to pass to ``update()``. Note that this is slow
+    (~2e5 it/s) since every input must be decoded as a number.
+* update_to  : bool, optional  
+    If true, will treat input as total elapsed iterations,
+    i.e. numbers to assign to ``self.n``. Note that this is slow
+    (~2e5 it/s) since every input must be decoded as a number.
+* null  : bool, optional  
+    If true, will discard input (no stdout).
+* manpath  : str, optional  
+    Directory in which to install tqdm man pages.
+* comppath  : str, optional  
+    Directory in which to place tqdm completion.
+* log  : str, optional  
+    CRITICAL|FATAL|ERROR|WARN(ING)|[default: 'INFO']|DEBUG|NOTSET.

+
+Description and additional stats
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Custom information can be displayed and updated dynamically on ``tqdm`` bars
+with the ``desc`` and ``postfix`` arguments:
+
+.. code:: python
+
+    from tqdm import tqdm, trange
+    from random import random, randint
+    from time import sleep
+
+    with trange(10) as t:
+        for i in t:
+            # Description will be displayed on the left
+            t.set_description('GEN %i' % i)
+            # Postfix will be displayed on the right,
+            # formatted automatically based on argument's datatype
+            t.set_postfix(loss=random(), gen=randint(1,999), str='h',
+                          lst=[1, 2])
+            sleep(0.1)
+
+    with tqdm(total=10, bar_format="{postfix[0]} {postfix[1][value]:>8.2g}",
+              postfix=["Batch", {"value": 0}]) as t:
+        for i in range(10):
+            sleep(0.1)
+            t.postfix[1]["value"] = i / 2
+            t.update()
+
+Points to remember when using ``{postfix[...]}`` in the ``bar_format`` string:
+
+- ``postfix`` also needs to be passed as an initial argument in a compatible
+  format, and
+- ``postfix`` will be auto-converted to a string if it is a ``dict``-like
+  object. To prevent this behaviour, insert an extra item into the dictionary
+  where the key is not a string.
+
+Additional ``bar_format`` parameters may also be defined by overriding
+``format_dict``, and the bar itself may be modified using ``ascii``:
+
+.. code:: python
+
+    from tqdm import tqdm
+    class TqdmExtraFormat(tqdm):
+        """Provides a `total_time` format parameter"""
+        @property
+        def format_dict(self):
+            d = super().format_dict
+            total_time = d["elapsed"] * (d["total"] or 0) / max(d["n"], 1)
+            d.update(total_time=self.format_interval(total_time) + " in total")
+            return d
+
+    for i in TqdmExtraFormat(
+          range(9), ascii=" .oO0",
+          bar_format="{total_time}: {percentage:.0f}%|{bar}{r_bar}"):
+        if i == 4:
+            break
+
+.. code::
+
+    00:00 in total: 44%|0000.     | 4/9 [00:00<00:00, 962.93it/s]
+
+Note that ``{bar}`` also supports a format specifier ``[width][type]``.
+
+- ``width``
+
+  * unspecified (default): automatic to fill ``ncols``
+  * ``int >= 0``: fixed width overriding ``ncols`` logic
+  * ``int < 0``: subtract from the automatic default
+
+- ``type``
+
+  * ``a``: ascii (``ascii=True`` override)
+  * ``u``: unicode (``ascii=False`` override)
+  * ``b``: blank (``ascii="  "`` override)
+
+This means a fixed bar with right-justified text may be created by using:
+``bar_format="{l_bar}{bar:10}|{bar:-10b}right-justified"``
+
+Nested progress bars
+~~~~~~~~~~~~~~~~~~~~
+
+``tqdm`` supports nested progress bars. Here's an example:
+
+.. code:: python
+
+    from tqdm.auto import trange
+    from time import sleep
+
+    for i in trange(4, desc='1st loop'):
+        for j in trange(5, desc='2nd loop'):
+            for k in trange(50, desc='3rd loop', leave=False):
+                sleep(0.01)
+
+For manual control over positioning (e.g. for multi-processing use),
+you may specify ``position=n`` where ``n=0`` for the outermost bar,
+``n=1`` for the next, and so on.
+However, it's best to check if ``tqdm`` can work without manual ``position``
+first.
+
+.. code:: python
+
+    from time import sleep
+    from tqdm import trange, tqdm
+    from multiprocessing import Pool, RLock, freeze_support
+
+    L = list(range(9))
+
+    def progresser(n):
+        interval = 0.001 / (n + 2)
+        total = 5000
+        text = f"#{n}, est. {interval * total:<04.2}s"
+        for _ in trange(total, desc=text, position=n):
+            sleep(interval)
+
+    if __name__ == '__main__':
+        freeze_support()  # for Windows support
+        tqdm.set_lock(RLock())  # for managing output contention
+        p = Pool(initializer=tqdm.set_lock, initargs=(tqdm.get_lock(),))
+        p.map(progresser, L)
+
+Note that in Python 3, ``tqdm.write`` is thread-safe:
+
+.. code:: python
+
+    from time import sleep
+    from tqdm import tqdm, trange
+    from concurrent.futures import ThreadPoolExecutor
+
+    L = list(range(9))
+
+    def progresser(n):
+        interval = 0.001 / (n + 2)
+        total = 5000
+        text = f"#{n}, est. {interval * total:<04.2}s"
+        for _ in trange(total, desc=text):
+            sleep(interval)
+        if n == 6:
+            tqdm.write("n == 6 completed.")
+            tqdm.write("`tqdm.write()` is thread-safe in py3!")
+
+    if __name__ == '__main__':
+        with ThreadPoolExecutor() as p:
+            p.map(progresser, L)
+
+Hooks and callbacks
+~~~~~~~~~~~~~~~~~~~
+
+``tqdm`` can easily support callbacks/hooks and manual updates.
+Here's an example with ``urllib``:
+
+**``urllib.urlretrieve`` documentation**
+
+    | [...]
+    | If present, the hook function will be called once
+    | on establishment of the network connection and once after each block read
+    | thereafter. The hook will be passed three arguments; a count of blocks
+    | transferred so far, a block size in bytes, and the total size of the file.
+    | [...]
+
+.. code:: python
+
+    import urllib, os
+    from tqdm import tqdm
+    urllib = getattr(urllib, 'request', urllib)
+
+    class TqdmUpTo(tqdm):
+        """Provides `update_to(n)` which uses `tqdm.update(delta_n)`."""
+        def update_to(self, b=1, bsize=1, tsize=None):
+            """
+            b  : int, optional
+                Number of blocks transferred so far [default: 1].
+            bsize  : int, optional
+                Size of each block (in tqdm units) [default: 1].
+            tsize  : int, optional
+                Total size (in tqdm units). If [default: None] remains unchanged.
+            """
+            if tsize is not None:
+                self.total = tsize
+            return self.update(b * bsize - self.n)  # also sets self.n = b * bsize
+
+    eg_link = "https://caspersci.uk.to/matryoshka.zip"
+    with TqdmUpTo(unit='B', unit_scale=True, unit_divisor=1024, miniters=1,
+                  desc=eg_link.split('/')[-1]) as t:  # all optional kwargs
+        urllib.urlretrieve(eg_link, filename=os.devnull,
+                           reporthook=t.update_to, data=None)
+        t.total = t.n
+
+Inspired by `twine#242 <https://github.com/pypa/twine/pull/242>`__.
+Functional alternative in
+`examples/tqdm_wget.py <https://github.com/tqdm/tqdm/blob/master/examples/tqdm_wget.py>`__.
+
+It is recommend to use ``miniters=1`` whenever there is potentially
+large differences in iteration speed (e.g. downloading a file over
+a patchy connection).
+
+**Wrapping read/write methods**
+
+To measure throughput through a file-like object's ``read`` or ``write``
+methods, use ``CallbackIOWrapper``:
+
+.. code:: python
+
+    from tqdm.auto import tqdm
+    from tqdm.utils import CallbackIOWrapper
+
+    with tqdm(total=file_obj.size,
+              unit='B', unit_scale=True, unit_divisor=1024) as t:
+        fobj = CallbackIOWrapper(t.update, file_obj, "read")
+        while True:
+            chunk = fobj.read(chunk_size)
+            if not chunk:
+                break
+        t.reset()
+        # ... continue to use `t` for something else
+
+Alternatively, use the even simpler ``wrapattr`` convenience function,
+which would condense both the ``urllib`` and ``CallbackIOWrapper`` examples
+down to:
+
+.. code:: python
+
+    import urllib, os
+    from tqdm import tqdm
+
+    eg_link = "https://caspersci.uk.to/matryoshka.zip"
+    response = getattr(urllib, 'request', urllib).urlopen(eg_link)
+    with tqdm.wrapattr(open(os.devnull, "wb"), "write",
+                       miniters=1, desc=eg_link.split('/')[-1],
+                       total=getattr(response, 'length', None)) as fout:
+        for chunk in response:
+            fout.write(chunk)
+
+The ``requests`` equivalent is nearly identical:
+
+.. code:: python
+
+    import requests, os
+    from tqdm import tqdm
+
+    eg_link = "https://caspersci.uk.to/matryoshka.zip"
+    response = requests.get(eg_link, stream=True)
+    with tqdm.wrapattr(open(os.devnull, "wb"), "write",
+                       miniters=1, desc=eg_link.split('/')[-1],
+                       total=int(response.headers.get('content-length', 0))) as fout:
+        for chunk in response.iter_content(chunk_size=4096):
+            fout.write(chunk)
+
+**Custom callback**
+
+``tqdm`` is known for intelligently skipping unnecessary displays. To make a
+custom callback take advantage of this, simply use the return value of
+``update()``. This is set to ``True`` if a ``display()`` was triggered.
+
+.. code:: python
+
+    from tqdm.auto import tqdm as std_tqdm
+
+    def external_callback(*args, **kwargs):
+        ...
+
+    class TqdmExt(std_tqdm):
+        def update(self, n=1):
+            displayed = super().update(n)
+            if displayed:
+                external_callback(**self.format_dict)
+            return displayed
+
+``asyncio``
+~~~~~~~~~~~
+
+Note that ``break`` isn't currently caught by asynchronous iterators.
+This means that ``tqdm`` cannot clean up after itself in this case:
+
+.. code:: python
+
+    from tqdm.asyncio import tqdm
+
+    async for i in tqdm(range(9)):
+        if i == 2:
+            break
+
+Instead, either call ``pbar.close()`` manually or use the context manager syntax:
+
+.. code:: python
+
+    from tqdm.asyncio import tqdm
+
+    with tqdm(range(9)) as pbar:
+        async for i in pbar:
+            if i == 2:
+                break
+
+Pandas Integration
+~~~~~~~~~~~~~~~~~~
+
+Due to popular demand we've added support for ``pandas`` -- here's an example
+for ``DataFrame.progress_apply`` and ``DataFrameGroupBy.progress_apply``:
+
+.. code:: python
+
+    import pandas as pd
+    import numpy as np
+    from tqdm import tqdm
+
+    df = pd.DataFrame(np.random.randint(0, 100, (100000, 6)))
+
+    # Register `pandas.progress_apply` and `pandas.Series.map_apply` with `tqdm`
+    # (can use `tqdm.gui.tqdm`, `tqdm.notebook.tqdm`, optional kwargs, etc.)
+    tqdm.pandas(desc="my bar!")
+
+    # Now you can use `progress_apply` instead of `apply`
+    # and `progress_map` instead of `map`
+    df.progress_apply(lambda x: x**2)
+    # can also groupby:
+    # df.groupby(0).progress_apply(lambda x: x**2)
+
+In case you're interested in how this works (and how to modify it for your
+own callbacks), see the
+`examples <https://github.com/tqdm/tqdm/tree/master/examples>`__
+folder or import the module and run ``help()``.
+
+Keras Integration
+~~~~~~~~~~~~~~~~~
+
+A ``keras`` callback is also available:
+
+.. code:: python
+
+    from tqdm.keras import TqdmCallback
+
+    ...
+
+    model.fit(..., verbose=0, callbacks=[TqdmCallback()])
+
+Dask Integration
+~~~~~~~~~~~~~~~~
+
+A ``dask`` callback is also available:
+
+.. code:: python
+
+    from tqdm.dask import TqdmCallback
+
+    with TqdmCallback(desc="compute"):
+        ...
+        arr.compute()
+
+    # or use callback globally
+    cb = TqdmCallback(desc="global")
+    cb.register()
+    arr.compute()
+
+IPython/Jupyter Integration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+IPython/Jupyter is supported via the ``tqdm.notebook`` submodule:
+
+.. code:: python
+
+    from tqdm.notebook import trange, tqdm
+    from time import sleep
+
+    for i in trange(3, desc='1st loop'):
+        for j in tqdm(range(100), desc='2nd loop'):
+            sleep(0.01)
+
+In addition to ``tqdm`` features, the submodule provides a native Jupyter
+widget (compatible with IPython v1-v4 and Jupyter), fully working nested bars
+and colour hints (blue: normal, green: completed, red: error/interrupt,
+light blue: no ETA); as demonstrated below.
+
+|Screenshot-Jupyter1|
+|Screenshot-Jupyter2|
+|Screenshot-Jupyter3|
+
+The ``notebook`` version supports percentage or pixels for overall width
+(e.g.: ``ncols='100%'`` or ``ncols='480px'``).
+
+It is also possible to let ``tqdm`` automatically choose between
+console or notebook versions by using the ``autonotebook`` submodule:
+
+.. code:: python
+
+    from tqdm.autonotebook import tqdm
+    tqdm.pandas()
+
+Note that this will issue a ``TqdmExperimentalWarning`` if run in a notebook
+since it is not meant to be possible to distinguish between ``jupyter notebook``
+and ``jupyter console``. Use ``auto`` instead of ``autonotebook`` to suppress
+this warning.
+
+Note that notebooks will display the bar in the cell where it was created.
+This may be a different cell from the one where it is used.
+If this is not desired, either
+
+- delay the creation of the bar to the cell where it must be displayed, or
+- create the bar with ``display=False``, and in a later cell call
+  ``display(bar.container)``:
+
+.. code:: python
+
+    from tqdm.notebook import tqdm
+    pbar = tqdm(..., display=False)
+
+.. code:: python
+
+    # different cell
+    display(pbar.container)
+
+The ``keras`` callback has a ``display()`` method which can be used likewise:
+
+.. code:: python
+
+    from tqdm.keras import TqdmCallback
+    cbk = TqdmCallback(display=False)
+
+.. code:: python
+
+    # different cell
+    cbk.display()
+    model.fit(..., verbose=0, callbacks=[cbk])
+
+Another possibility is to have a single bar (near the top of the notebook)
+which is constantly re-used (using ``reset()`` rather than ``close()``).
+For this reason, the notebook version (unlike the CLI version) does not
+automatically call ``close()`` upon ``Exception``.
+
+.. code:: python
+
+    from tqdm.notebook import tqdm
+    pbar = tqdm()
+
+.. code:: python
+
+    # different cell
+    iterable = range(100)
+    pbar.reset(total=len(iterable))  # initialise with new `total`
+    for i in iterable:
+        pbar.update()
+    pbar.refresh()  # force print final status but don't `close()`
+
+Custom Integration
+~~~~~~~~~~~~~~~~~~
+
+To change the default arguments (such as making ``dynamic_ncols=True``),
+simply use built-in Python magic:
+
+.. code:: python
+
+    from functools import partial
+    from tqdm import tqdm as std_tqdm
+    tqdm = partial(std_tqdm, dynamic_ncols=True)
+
+For further customisation,
+``tqdm`` may be inherited from to create custom callbacks (as with the
+``TqdmUpTo`` example `above <#hooks-and-callbacks>`__) or for custom frontends
+(e.g. GUIs such as notebook or plotting packages). In the latter case:
+
+1. ``def __init__()`` to call ``super().__init__(..., gui=True)`` to disable
+   terminal ``status_printer`` creation.
+2. Redefine: ``close()``, ``clear()``, ``display()``.
+
+Consider overloading ``display()`` to use e.g.
+``self.frontend(**self.format_dict)`` instead of ``self.sp(repr(self))``.

+Dynamic Monitor/Meter
+~~~~~~~~~~~~~~~~~~~~~
+
+You can use a ``tqdm`` as a meter which is not monotonically increasing.
+This could be because ``n`` decreases (e.g. a CPU usage monitor) or ``total``
+changes.
+
+One example would be recursively searching for files. The ``total`` is the
+number of objects found so far, while ``n`` is the number of those objects which
+are files (rather than folders):
+
+.. code:: python
+
+    from tqdm import tqdm
+    import os.path
+
+    def find_files_recursively(path, show_progress=True):
+        files = []
+        # total=1 assumes `path` is a file
+        t = tqdm(total=1, unit="file", disable=not show_progress)
+        if not os.path.exists(path):
+            raise IOError("Cannot find:" + path)
+
+        def append_found_file(f):
+            files.append(f)
+            t.update()
+
+        def list_found_dir(path):
+            """returns os.listdir(path) assuming os.path.isdir(path)"""
+            listing = os.listdir(path)
+            # subtract 1 since a "file" we found was actually this directory
+            t.total += len(listing) - 1
+            # fancy way to give info without forcing a refresh
+            t.set_postfix(dir=path[-10:], refresh=False)
+            t.update(0)  # may trigger a refresh
+            return listing
+
+        def recursively_search(path):
+            if os.path.isdir(path):
+                for f in list_found_dir(path):
+                    recursively_search(os.path.join(path, f))
+            else:
+                append_found_file(path)
+
+        recursively_search(path)
+        t.set_postfix(dir=path)
+        t.close()
+        return files
+
+Using ``update(0)`` is a handy way to let ``tqdm`` decide when to trigger a
+display refresh to avoid console spamming.
+
+Writing messages
+~~~~~~~~~~~~~~~~
+
+This is a work in progress (see
+`#737 <https://github.com/tqdm/tqdm/issues/737>`__).
+
+Since ``tqdm`` uses a simple printing mechanism to display progress bars,
+you should not write any message in the terminal using ``print()`` while
+a progressbar is open.
+
+To write messages in the terminal without any collision with ``tqdm`` bar
+display, a ``.write()`` method is provided:
+
+.. code:: python
+
+    from tqdm.auto import tqdm, trange
+    from time import sleep
+
+    bar = trange(10)
+    for i in bar:
+        # Print using tqdm class method .write()
+        sleep(0.1)
+        if not (i % 3):
+            tqdm.write("Done task %i" % i)
+        # Can also use bar.write()
+
+By default, this will print to standard output ``sys.stdout``. but you can
+specify any file-like object using the ``file`` argument. For example, this
+can be used to redirect the messages writing to a log file or class.
+
+Redirecting writing
+~~~~~~~~~~~~~~~~~~~
+
+If using a library that can print messages to the console, editing the library
+by  replacing ``print()`` with ``tqdm.write()`` may not be desirable.
+In that case, redirecting ``sys.stdout`` to ``tqdm.write()`` is an option.
+
+To redirect ``sys.stdout``, create a file-like class that will write
+any input string to ``tqdm.write()``, and supply the arguments
+``file=sys.stdout, dynamic_ncols=True``.
+
+A reusable canonical example is given below:
+
+.. code:: python
+
+    from time import sleep
+    import contextlib
+    import sys
+    from tqdm import tqdm
+    from tqdm.contrib import DummyTqdmFile
+
+
+    @contextlib.contextmanager
+    def std_out_err_redirect_tqdm():
+        orig_out_err = sys.stdout, sys.stderr
+        try:
+            sys.stdout, sys.stderr = map(DummyTqdmFile, orig_out_err)
+            yield orig_out_err[0]
+        # Relay exceptions
+        except Exception as exc:
+            raise exc
+        # Always restore sys.stdout/err if necessary
+        finally:
+            sys.stdout, sys.stderr = orig_out_err
+
+    def some_fun(i):
+        print("Fee, fi, fo,".split()[i])
+
+    # Redirect stdout to tqdm.write() (don't forget the `as save_stdout`)
+    with std_out_err_redirect_tqdm() as orig_stdout:
+        # tqdm needs the original stdout
+        # and dynamic_ncols=True to autodetect console width
+        for i in tqdm(range(3), file=orig_stdout, dynamic_ncols=True):
+            sleep(.5)
+            some_fun(i)
+
+    # After the `with`, printing is restored
+    print("Done!")
+
+Redirecting ``logging``
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Similar to ``sys.stdout``/``sys.stderr`` as detailed above, console ``logging``
+may also be redirected to ``tqdm.write()``.
+
+Warning: if also redirecting ``sys.stdout``/``sys.stderr``, make sure to
+redirect ``logging`` first if needed.
+
+Helper methods are available in ``tqdm.contrib.logging``. For example:
+
+.. code:: python
+
+    import logging
+    from tqdm import trange
+    from tqdm.contrib.logging import logging_redirect_tqdm
+
+    LOG = logging.getLogger(__name__)
+
+    if __name__ == '__main__':
+        logging.basicConfig(level=logging.INFO)
+        with logging_redirect_tqdm():
+            for i in trange(9):
+                if i == 4:
+                    LOG.info("console logging redirected to `tqdm.write()`")
+        # logging restored
+
+Monitoring thread, intervals and miniters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+``tqdm`` implements a few tricks to increase efficiency and reduce overhead.
+
+- Avoid unnecessary frequent bar refreshing: ``mininterval`` defines how long
+  to wait between each refresh. ``tqdm`` always gets updated in the background,
+  but it will display only every ``mininterval``.
+- Reduce number of calls to check system clock/time.
+- ``mininterval`` is more intuitive to configure than ``miniters``.
+  A clever adjustment system ``dynamic_miniters`` will automatically adjust
+  ``miniters`` to the amount of iterations that fit into time ``mininterval``.
+  Essentially, ``tqdm`` will check if it's time to print without actually
+  checking time. This behaviour can be still be bypassed by manually setting
+  ``miniters``.
+
+However, consider a case with a combination of fast and slow iterations.
+After a few fast iterations, ``dynamic_miniters`` will set ``miniters`` to a
+large number. When iteration rate subsequently slows, ``miniters`` will
+remain large and thus reduce display update frequency. To address this:
+
+- ``maxinterval`` defines the maximum time between display refreshes.
+  A concurrent monitoring thread checks for overdue updates and forces one
+  where necessary.
+
+The monitoring thread should not have a noticeable overhead, and guarantees
+updates at least every 10 seconds by default.
+This value can be directly changed by setting the ``monitor_interval`` of
+any ``tqdm`` instance (i.e. ``t = tqdm.tqdm(...); t.monitor_interval = 2``).
+The monitor thread may be disabled application-wide by setting
+``tqdm.tqdm.monitor_interval = 0`` before instantiation of any ``tqdm`` bar.

+        The width of the entire output message. If specified,

+        If unspecified, attempts to use environment width. The
+        fallback is a meter width of 10 and no limit for the counter and
+        statistics. If 0, will not print any meter (only stats).
+    mininterval  : float, optional
+        Minimum progress display update interval [default: 0.1] seconds.
+    maxinterval  : float, optional
+        Maximum progress display update interval [default: 10] seconds.
+        Automatically adjusts `miniters` to correspond to `mininterval`

+        Minimum progress display update interval, in iterations.

+        Tweak this and `mininterval` to get very efficient loops.
+        If your progress is erratic with both fast and slow iterations

+    ascii  : bool or str, optional
+        If unspecified or False, use unicode (smooth blocks) to fill

+    disable  : bool, optional
+        Whether to disable the entire progressbar wrapper
+        [default: False]. If set to None, disable on non-TTY.
+    unit  : str, optional
+        String that will be used to define the unit of each iteration
+        [default: it].
+    unit_scale  : bool or int or float, optional
+        If 1 or True, the number of iterations will be reduced/scaled

+        bar [default: 0]. If using float, consider specifying `{n:.3f}`
+        or similar in `bar_format`, or specifying `unit_scale`.

+    lock_args  : tuple, optional
+        Passed to `refresh` for intermediate output
+        (initialisation, iterating, and updating).
+    nrows  : int, optional

+.SH OPTIONS
+.TP
+.B \-h, \-\-help
+Print this help and exit.
+.RS
+.RE
+.TP
+.B \-v, \-\-version
+Print version and exit.
+.RS
+.RE
+.TP
+.B \-\-desc=\f[I]desc\f[]
+str, optional.
+Prefix for the progressbar.
+.RS
+.RE
+.TP
+.B \-\-total=\f[I]total\f[]
+int or float, optional.
+The number of expected iterations.
+If unspecified, len(iterable) is used if possible.
+If float("inf") or as a last resort, only basic progress statistics are
+displayed (no ETA, no progressbar).
+If \f[C]gui\f[] is True and this parameter needs subsequent updating,
+specify an initial arbitrary large positive number, e.g.
+9e9.
+.RS
+.RE
+.TP
+.B \-\-leave
+bool, optional.
+If [default: True], keeps all traces of the progressbar upon termination
+of iteration.
+If \f[C]None\f[], will leave only if \f[C]position\f[] is \f[C]0\f[].
+.RS
+.RE
+.TP
+.B \-\-ncols=\f[I]ncols\f[]
+int, optional.
+The width of the entire output message.
+If specified, dynamically resizes the progressbar to stay within this
+bound.
+If unspecified, attempts to use environment width.
+The fallback is a meter width of 10 and no limit for the counter and
+statistics.
+If 0, will not print any meter (only stats).
+.RS
+.RE
+.TP
+.B \-\-mininterval=\f[I]mininterval\f[]
+float, optional.
+Minimum progress display update interval [default: 0.1] seconds.
+.RS
+.RE
+.TP
+.B \-\-maxinterval=\f[I]maxinterval\f[]
+float, optional.
+Maximum progress display update interval [default: 10] seconds.
+Automatically adjusts \f[C]miniters\f[] to correspond to
+\f[C]mininterval\f[] after long display update lag.
+Only works if \f[C]dynamic_miniters\f[] or monitor thread is enabled.
+.RS
+.RE
+.TP
+.B \-\-miniters=\f[I]miniters\f[]
+int or float, optional.
+Minimum progress display update interval, in iterations.
+If 0 and \f[C]dynamic_miniters\f[], will automatically adjust to equal
+\f[C]mininterval\f[] (more CPU efficient, good for tight loops).
+If > 0, will skip display of specified number of iterations.
+Tweak this and \f[C]mininterval\f[] to get very efficient loops.
+If your progress is erratic with both fast and slow iterations (network,
+skipping items, etc) you should set miniters=1.
+.RS
+.RE
+.TP
+.B \-\-ascii=\f[I]ascii\f[]
+bool or str, optional.
+If unspecified or False, use unicode (smooth blocks) to fill the meter.
+The fallback is to use ASCII characters " 123456789#".
+.RS
+.RE
+.TP
+.B \-\-disable
+bool, optional.
+Whether to disable the entire progressbar wrapper [default: False].
+If set to None, disable on non\-TTY.
+.RS
+.RE
+.TP
+.B \-\-unit=\f[I]unit\f[]
+str, optional.
+String that will be used to define the unit of each iteration [default:
+it].
+.RS
+.RE
+.TP
+.B \-\-unit\-scale=\f[I]unit_scale\f[]
+bool or int or float, optional.
+If 1 or True, the number of iterations will be reduced/scaled
+automatically and a metric prefix following the International System of
+Units standard will be added (kilo, mega, etc.) [default: False].
+If any other non\-zero number, will scale \f[C]total\f[] and \f[C]n\f[].
+.RS
+.RE
+.TP
+.B \-\-dynamic\-ncols
+bool, optional.
+If set, constantly alters \f[C]ncols\f[] and \f[C]nrows\f[] to the
+environment (allowing for window resizes) [default: False].
+.RS
+.RE
+.TP
+.B \-\-smoothing=\f[I]smoothing\f[]
+float, optional.
+Exponential moving average smoothing factor for speed estimates (ignored
+in GUI mode).
+Ranges from 0 (average speed) to 1 (current/instantaneous speed)
+[default: 0.3].
+.RS
+.RE
+.TP
+.B \-\-bar\-format=\f[I]bar_format\f[]
+str, optional.
+Specify a custom bar string formatting.
+May impact performance.
+[default: \[aq]{l_bar}{bar}{r_bar}\[aq]], where l_bar=\[aq]{desc}:
+{percentage:3.0f}%|\[aq] and r_bar=\[aq]| {n_fmt}/{total_fmt}

+unit_divisor, remaining, remaining_s, eta.
+Note that a trailing ": " is automatically removed after {desc} if the
+latter is empty.
+.RS
+.RE
+.TP
+.B \-\-initial=\f[I]initial\f[]
+int or float, optional.
+The initial counter value.
+Useful when restarting a progress bar [default: 0].
+If using float, consider specifying \f[C]{n:.3f}\f[] or similar in
+\f[C]bar_format\f[], or specifying \f[C]unit_scale\f[].
+.RS
+.RE
+.TP
+.B \-\-position=\f[I]position\f[]
+int, optional.
+Specify the line offset to print this bar (starting from 0) Automatic if
+unspecified.
+Useful to manage multiple bars at once (eg, from threads).
+.RS
+.RE
+.TP
+.B \-\-postfix=\f[I]postfix\f[]
+dict or *, optional.
+Specify additional stats to display at the end of the bar.
+Calls \f[C]set_postfix(**postfix)\f[] if possible (dict).
+.RS
+.RE
+.TP
+.B \-\-unit\-divisor=\f[I]unit_divisor\f[]
+float, optional.

+iterating, and updating).
+.RS
+.RE
+.TP
+.B \-\-nrows=\f[I]nrows\f[]
+int, optional.
+The screen height.
+If specified, hides nested bars outside this bound.
+If unspecified, attempts to use environment height.
+The fallback is 20.
+.RS
+.RE
+.TP
+.B \-\-colour=\f[I]colour\f[]

+# Typing Extensions
+
+[![Chat at https://gitter.im/python/typing](https://badges.gitter.im/python/typing.svg)](https://gitter.im/python/typing)
+
+[Documentation](https://typing-extensions.readthedocs.io/en/latest/#) –
+[PyPI](https://pypi.org/project/typing-extensions/)
+
+## Overview
+
+The `typing_extensions` module serves two related purposes:
+
+- Enable use of new type system features on older Python versions. For example,
+  `typing.TypeGuard` is new in Python 3.10, but `typing_extensions` allows
+  users on previous Python versions to use it too.
+- Enable experimentation with new type system PEPs before they are accepted and
+  added to the `typing` module.
+
+`typing_extensions` is treated specially by static type checkers such as
+mypy and pyright. Objects defined in `typing_extensions` are treated the same
+way as equivalent forms in `typing`.
+
+`typing_extensions` uses
+[Semantic Versioning](https://semver.org/). The
+major version will be incremented only for backwards-incompatible changes.
+Therefore, it's safe to depend
+on `typing_extensions` like this: `typing_extensions ~=x.y`,
+where `x.y` is the first version that includes all features you need.
+[This](https://packaging.python.org/en/latest/specifications/version-specifiers/#compatible-release)
+is equivalent to `typing_extensions >=x.y, <(x+1)`. Do not depend on `~= x.y.z`
+unless you really know what you're doing; that defeats the purpose of
+semantic versioning.
+

+A. HISTORY OF THE SOFTWARE
+==========================
+
+Python was created in the early 1990s by Guido van Rossum at Stichting
+Mathematisch Centrum (CWI, see https://www.cwi.nl) in the Netherlands
+as a successor of a language called ABC.  Guido remains Python's
+principal author, although it includes many contributions from others.
+
+In 1995, Guido continued his work on Python at the Corporation for
+National Research Initiatives (CNRI, see https://www.cnri.reston.va.us)
+in Reston, Virginia where he released several versions of the
+software.
+
+In May 2000, Guido and the Python core development team moved to
+BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
+year, the PythonLabs team moved to Digital Creations, which became
+Zope Corporation.  In 2001, the Python Software Foundation (PSF, see
+https://www.python.org/psf/) was formed, a non-profit organization
+created specifically to own Python-related Intellectual Property.
+Zope Corporation was a sponsoring member of the PSF.
+
+All Python releases are Open Source (see https://opensource.org for
+the Open Source Definition).  Historically, most, but not all, Python
+releases have also been GPL-compatible; the table below summarizes
+the various releases.
+

+(1) GPL-compatible doesn't mean that we're distributing Python under
+    the GPL.  All Python licenses, unlike the GPL, let you distribute
+    a modified version without making your changes open source.  The
+    GPL-compatible licenses make it possible to combine Python with
+    other software that is released under the GPL; the others don't.
+
+(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
+    because its license has a choice of law clause.  According to
+    CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
+    is "not incompatible" with the GPL.
+
+Thanks to the many outside volunteers who have worked under Guido's
+direction to make these releases possible.

+
+        TypedDict creates a dictionary type such that a type checker will expect all
+        instances to have a certain set of keys, where each key is
+        associated with a value of a consistent type. This expectation
+        is not checked at runtime.
+
+        Usage::
+
+            class Point2D(TypedDict):
+                x: int
+                y: int
+                label: str
+
+            a: Point2D = {'x': 1, 'y': 2, 'label': 'good'}  # OK
+            b: Point2D = {'z': 3, 'label': 'bad'}           # Fails type check
+
+            assert Point2D(x=1, y=2, label='first') == dict(x=1, y=2, label='first')
+
+        The type info can be accessed via the Point2D.__annotations__ dict, and
+        the Point2D.__required_keys__ and Point2D.__optional_keys__ frozensets.
+        TypedDict supports an additional equivalent form::
+
+            Point2D = TypedDict('Point2D', {'x': int, 'y': int, 'label': str})
+
+        By default, all keys must be present in a TypedDict. It is possible
+        to override this by specifying totality::
+
+            class Point2D(TypedDict, total=False):
+                x: int
+                y: int
+
+        This means that a Point2D TypedDict can have any of the keys omitted. A type
+        checker is only expected to support a literal False or True as the value of
+        the total argument. True is the default, and makes all items defined in the
+        class body be required.
+
+        The Required and NotRequired special forms can also be used to mark
+        individual keys as being required or not required::
+
+            class Point2D(TypedDict):
+                x: int  # the "x" key must always be present (Required is the default)
+                y: NotRequired[int]  # the "y" key can be omitted
+
+        See PEP 655 for more details on Required and NotRequired.

+        Usage::
+
+           P = ParamSpec('P')
+
+        Parameter specification variables exist primarily for the benefit of static
+        type checkers.  They are used to forward the parameter types of one
+        callable to another callable, a pattern commonly found in higher order
+        functions and decorators.  They are only valid when used in ``Concatenate``,
+        or s the first argument to ``Callable``. In Python 3.10 and higher,
+        they are also supported in user-defined Generics at runtime.
+        See class Generic for more information on generic types.  An
+        example for annotating a decorator::
+
+           T = TypeVar('T')
+           P = ParamSpec('P')
+
+           def add_logging(f: Callable[P, T]) -> Callable[P, T]:
+               '''A type-safe decorator to add logging to a function.'''
+               def inner(*args: P.args, **kwargs: P.kwargs) -> T:
+                   logging.info(f'{f.__name__} was called')
+                   return f(*args, **kwargs)
+               return inner
+
+           @add_logging
+           def add_two(x: float, y: float) -> float:
+               '''Add two numbers together.'''
+               return x + y
+
+        Parameter specification variables defined with covariant=True or
+        contravariant=True can be used to declare covariant or contravariant
+        generic types.  These keyword arguments are valid, but their actual semantics
+        are yet to be decided.  See PEP 612 for details.
+
+        Parameter specification variables can be introspected. e.g.:
+
+           P.__name__ == 'T'
+           P.__bound__ == None
+           P.__covariant__ == False
+           P.__contravariant__ == False
+
+        Note that only parameter specification variables defined in global scope can
+        be pickled.

+
+        Usage::
+
+            Ts = TypeVarTuple('Ts')
+
+        In the same way that a normal type variable is a stand-in for a single
+        type such as ``int``, a type variable *tuple* is a stand-in for a *tuple*
+        type such as ``Tuple[int, str]``.
+
+        Type variable tuples can be used in ``Generic`` declarations.
+        Consider the following example::
+
+            class Array(Generic[*Ts]): ...
+
+        The ``Ts`` type variable tuple here behaves like ``tuple[T1, T2]``,
+        where ``T1`` and ``T2`` are type variables. To use these type variables
+        as type parameters of ``Array``, we must *unpack* the type variable tuple using
+        the star operator: ``*Ts``. The signature of ``Array`` then behaves
+        as if we had simply written ``class Array(Generic[T1, T2]): ...``.
+        In contrast to ``Generic[T1, T2]``, however, ``Generic[*Shape]`` allows
+        us to parameterise the class with an *arbitrary* number of type parameters.
+
+        Type variable tuples can be used anywhere a normal ``TypeVar`` can.
+        This includes class definitions, as shown above, as well as function
+        signatures and variable annotations::
+
+            class Array(Generic[*Ts]):
+
+                def __init__(self, shape: Tuple[*Ts]):
+                    self._shape: Tuple[*Ts] = shape

+        it's called; calling it twice on the same object will return two
+        different but equivalent dicts.
+
+        This is a backport of `inspect.get_annotations`, which has been
+        in the standard library since Python 3.10. See the standard library
+        documentation for more:
+
+            https://docs.python.org/3/library/inspect.html#inspect.get_annotations
+
+        This backport adds the *format* argument introduced by PEP 649. The
+        three formats supported are:
+        * VALUE: the annotations are returned as-is. This is the default and
+          it is compatible with the behavior on previous Python versions.
+        * FORWARDREF: return annotations as-is if possible, but replace any
+          undefined names with ForwardRef objects. The implementation proposed by
+          PEP 649 relies on language changes that cannot be backported; the
+          typing-extensions implementation simply returns the same result as VALUE.
+        * STRING: return annotations as strings, in a format close to the original
+          source. Again, this behavior cannot be replicated directly in a backport.
+          As an approximation, typing-extensions retrieves the annotations under
+          VALUE semantics and then stringifies them.
+
+        The purpose of this backport is to allow users who would like to use
+        FORWARDREF or STRING semantics once PEP 649 is implemented, but who also
+        want to support earlier Python versions, to simply write:

+
+urllib3 is a powerful, *user-friendly* HTTP client for Python. Much of the
+Python ecosystem already uses urllib3 and you should too.
+urllib3 brings many critical features that are missing from the Python
+standard libraries:
+
+- Thread safety.
+- Connection pooling.
+- Client-side SSL/TLS verification.
+- File uploads with multipart encoding.
+- Helpers for retrying requests and dealing with HTTP redirects.
+- Support for gzip, deflate, brotli, and zstd encoding.
+- Proxy support for HTTP and SOCKS.
+- 100% test coverage.
+
+urllib3 is powerful and easy to use:
+
+```python3
+>>> import urllib3
+>>> resp = urllib3.request("GET", "http://httpbin.org/robots.txt")
+>>> resp.status
+200
+>>> resp.data
+b"User-agent: *\nDisallow: /deny\n"
+```
+
+## Installing
+
+urllib3 can be installed with [pip](https://pip.pypa.io):

+        signing, such as with OAuth.
+
+        Supports an optional ``fields`` parameter of key/value strings AND

+            }
+
+        When uploading a file, providing a filename (the first parameter of the
+        tuple) is optional but recommended to best mimic behavior of browsers.
+
+        Note that if ``headers`` are supplied, the 'Content-Type' header will
+        be overwritten because it depends on the dynamic random boundary string
+        which is used to compose the body of the request. The random boundary

+Support for streaming http requests in emscripten.
+
+A few caveats -
+
+If your browser (or Node.js) has WebAssembly JavaScript Promise Integration enabled
+https://github.com/WebAssembly/js-promise-integration/blob/main/proposals/js-promise-integration/Overview.md
+*and* you launch pyodide using `pyodide.runPythonAsync`, this will fetch data using the
+JavaScript asynchronous fetch api (wrapped via `pyodide.ffi.call_sync`). In this case
+timeouts and streaming should just work.
+
+Otherwise, it uses a combination of XMLHttpRequest and a web-worker for streaming.
+
+This approach has several caveats:
+
+Firstly, you can't do streaming http in the main UI thread, because atomics.wait isn't allowed.
+Streaming only works if you're running pyodide in a web worker.
+
+Secondly, this uses an extra web worker and SharedArrayBuffer to do the asynchronous fetch
+operation, so it requires that you have crossOriginIsolation enabled, by serving over https
+(or from localhost) with the two headers below set:
+
+    Cross-Origin-Opener-Policy: same-origin
+    Cross-Origin-Embedder-Policy: require-corp
+
+You can tell if cross origin isolation is successfully enabled by looking at the global crossOriginIsolated variable in
+JavaScript console. If it isn't, streaming requests will fallback to XMLHttpRequest, i.e. getting the whole
+request into a buffer and then returning it. it shows a warning in the JavaScript console in this case.
+
+Finally, the webworker which does the streaming fetch is created on initial import, but will only be started once
+control is returned to javascript. Call `await wait_for_streaming_ready()` to wait for streaming fetch.
+
+NB: in this code, there are a lot of JavaScript objects. They are named js_*
+to make it clear what type of object they are.

+"""
+Module for using pyOpenSSL as a TLS backend. This module was relevant before
+the standard library ``ssl`` module supported SNI, but now that we've dropped
+support for Python 2.7 all relevant Python versions support SNI so
+**this module is no longer recommended**.
+
+This needs the following packages installed:
+
+* `pyOpenSSL`_ (tested with 16.0.0)
+* `cryptography`_ (minimum 1.3.4, from pyopenssl)
+* `idna`_ (minimum 2.0)
+
+However, pyOpenSSL depends on cryptography, so while we use all three directly here we
+end up having relatively few packages required.
+
+You can install them with the following command:
+
+.. code-block:: bash
+
+    $ python -m pip install pyopenssl cryptography idna
+
+To activate certificate checking, call
+:func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code
+before you begin making HTTP requests. This can be done in a ``sitecustomize``
+module, or at any other time before your application begins using ``urllib3``,
+like this:
+
+.. code-block:: python
+
+    try:
+        import urllib3.contrib.pyopenssl
+        urllib3.contrib.pyopenssl.inject_into_urllib3()
+    except ImportError:
+        pass
+
+.. _pyopenssl: https://www.pyopenssl.org
+.. _cryptography: https://cryptography.io
+.. _idna: https://github.com/kjd/idna

+"""
+This module contains provisional support for SOCKS proxies from within
+urllib3. This module supports SOCKS4, SOCKS4A (an extension of SOCKS4), and
+SOCKS5. To enable its functionality, either install PySocks or install this
+module with the ``socks`` extra.
+
+The SOCKS implementation supports the full range of urllib3 features. It also
+supports the following SOCKS features:
+
+- SOCKS4A (``proxy_url='socks4a://...``)
+- SOCKS4 (``proxy_url='socks4://...``)
+- SOCKS5 with remote DNS (``proxy_url='socks5h://...``)
+- SOCKS5 with local DNS (``proxy_url='socks5://...``)
+- Usernames and passwords for the SOCKS proxy
+
+.. note::
+   It is recommended to use ``socks5h://`` or ``socks4a://`` schemes in
+   your ``proxy_url`` to ensure that DNS resolution is done from the remote
+   server instead of client-side when connecting to a domain name.
+
+SOCKS4 supports IPv4 and domain names with the SOCKS4A extension. SOCKS5
+supports IPv4, IPv6, and domain names.
+
+When connecting to a SOCKS4 proxy the ``username`` portion of the ``proxy_url``
+will be sent as the ``userid`` section of the SOCKS request:
+
+.. code-block:: python
+
+    proxy_url="socks4a://<userid>@proxy-host"
+
+When connecting to a SOCKS5 proxy the ``username`` and ``password`` portion
+of the ``proxy_url`` will be sent as the username/password to authenticate
+with the proxy:
+
+.. code-block:: python
+
+    proxy_url="socks5h://<username>:<password>@proxy-host"

+
+    Each retry attempt will create a new Retry object with updated values, so
+    they can be safely reused.
+
+    Retries can be defined as a default for a pool:
+
+    .. code-block:: python
+
+        retries = Retry(connect=5, read=2, redirect=5)
+        http = PoolManager(retries=retries)
+        response = http.request("GET", "https://example.com/")
+
+    Or per-request (which overrides the default for the pool):
+
+    .. code-block:: python
+
+        response = http.request("GET", "https://example.com/", retries=Retry(10))
+
+    Retries can be disabled by passing ``False``:
+
+    .. code-block:: python
+
+        response = http.request("GET", "https://example.com/", retries=False)
+
+    Errors will be wrapped in :class:`~urllib3.exceptions.MaxRetryError` unless
+    retries are disabled, in which case the causing exception will be raised.
+
+    :param int total:
+        Total number of retries to allow. Takes precedence over other counts.
+
+        Set to ``None`` to remove this constraint and fall back on other
+        counts.
+
+        Set to ``0`` to fail on the first retry.
+
+        Set to ``False`` to disable and imply ``raise_on_redirect=False``.
+
+    :param int connect:
+        How many connection-related errors to retry on.
+
+        These are errors raised before the request is sent to the remote server,
+        which we assume has not triggered the server to process the request.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int read:
+        How many times to retry on read errors.
+
+        These errors are raised after the request was sent to the server, so the
+        request may have side-effects.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int redirect:
+        How many redirects to perform. Limit this to avoid infinite redirect
+        loops.
+
+        A redirect is a HTTP response with a status code 301, 302, 303, 307 or
+        308.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+        Set to ``False`` to disable and imply ``raise_on_redirect=False``.
+
+    :param int status:
+        How many times to retry on bad status codes.
+
+        These are retries made on responses, where status code matches
+        ``status_forcelist``.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+    :param int other:
+        How many times to retry on other errors.
+
+        Other errors are errors that are not connect, read, redirect or status errors.
+        These errors might be raised after the request was sent to the server, so the
+        request might have side-effects.
+
+        Set to ``0`` to fail on the first retry of this type.
+
+        If ``total`` is not set, it's a good idea to set this to 0 to account
+        for unexpected edge cases and avoid infinite retry loops.
+
+    :param Collection allowed_methods:
+        Set of uppercased HTTP method verbs that we should retry on.
+
+        By default, we only retry on methods which are considered to be
+        idempotent (multiple requests with the same parameters end with the
+        same state). See :attr:`Retry.DEFAULT_ALLOWED_METHODS`.
+
+        Set to a ``None`` value to retry on any verb.
+
+    :param Collection status_forcelist:
+        A set of integer HTTP status codes that we should force a retry on.
+        A retry is initiated if the request method is in ``allowed_methods``
+        and the response status code is in ``status_forcelist``.
+
+        By default, this is disabled with ``None``.
+
+    :param float backoff_factor:
+        A backoff factor to apply between attempts after the second try
+        (most errors are resolved immediately by a second try without a
+        delay). urllib3 will sleep for::
+
+            {backoff factor} * (2 ** ({number of previous retries}))
+
+        seconds. If `backoff_jitter` is non-zero, this sleep is extended by::
+
+            random.uniform(0, {backoff jitter})
+
+        seconds. For example, if the backoff_factor is 0.1, then :func:`Retry.sleep` will
+        sleep for [0.0s, 0.2s, 0.4s, 0.8s, ...] between retries. No backoff will ever
+        be longer than `backoff_max`.
+
+        By default, backoff is disabled (factor set to 0).
+
+    :param bool raise_on_redirect: Whether, if the number of redirects is
+        exhausted, to raise a MaxRetryError, or to return a response with a
+        response code in the 3xx range.
+
+    :param bool raise_on_status: Similar meaning to ``raise_on_redirect``:
+        whether we should raise an exception, or return a response,
+        if status falls in ``status_forcelist`` range and retries have
+        been exhausted.
+
+    :param tuple history: The history of the request encountered during
+        each call to :meth:`~Retry.increment`. The list is in the order
+        the requests occurred. Each list item is of class :class:`RequestHistory`.
+
+    :param bool respect_retry_after_header:
+        Whether to respect Retry-After header on status codes defined as
+        :attr:`Retry.RETRY_AFTER_STATUS_CODES` or not.
+
+    :param Collection remove_headers_on_redirect:
+        Sequence of headers to remove from the request when a response
+        indicating a redirect is returned before firing off the redirected
+        request.

+        This combines the connect and read timeouts into one; the read timeout

+
+        For example, Python's DNS resolver does not obey the timeout specified
+        on the socket. Other factors that can affect total request time include
+        high CPU load, high swap, the program running at a low priority level,
+        or other behaviors.
+
+        In addition, the read and total timeouts only measure the time between
+        read operations on the socket connecting the client and the server,
+        not the total amount of time for the request to return a complete
+        response. For most requests, the timeout is raised because the server
+        has not sent the first byte in the specified time. This is not always
+        the case; if a server streams one byte every fifteen seconds, a timeout
+        of 20 seconds will not trigger, even though the request will take
+        several minutes to complete.

+# and don't want to keep track of state, so the stateless APIs are actually
+# more efficient. So we want to use select() or poll().
+#
+# Now, how do we choose between select() and poll()? On traditional Unixes,
+# select() has a strange calling convention that makes it slow, or fail
+# altogether, for high-numbered file descriptors. The point of poll() is to fix
+# that, so on Unixes, we prefer poll().
+#
+# On Windows, there is no poll() (or at least Python doesn't provide a wrapper
+# for it), but that's OK, because on Windows, select() doesn't have this
+# strange calling convention; plain select() works fine.

+# Werkzeug
+
+*werkzeug* German noun: "tool". Etymology: *werk* ("work"), *zeug* ("stuff")
+
+Werkzeug is a comprehensive [WSGI][] web application library. It began as
+a simple collection of various utilities for WSGI applications and has
+become one of the most advanced WSGI utility libraries.
+
+It includes:
+
+-   An interactive debugger that allows inspecting stack traces and
+    source code in the browser with an interactive interpreter for any
+    frame in the stack.
+-   A full-featured request object with objects to interact with
+    headers, query args, form data, files, and cookies.
+-   A response object that can wrap other WSGI applications and handle
+    streaming data.
+-   A routing system for matching URLs to endpoints and generating URLs
+    for endpoints, with an extensible system for capturing variables
+    from URLs.
+-   HTTP utilities to handle entity tags, cache control, dates, user
+    agents, cookies, files, and more.
+-   A threaded WSGI server for use while developing applications
+    locally.
+-   A test client for simulating HTTP requests during testing without
+    requiring running a server.
+
+Werkzeug doesn't enforce any dependencies. It is up to the developer to
+choose a template engine, database adapter, and even how to handle
+requests. It can be used to build all sorts of end user applications
+such as blogs, wikis, or bulletin boards.
+
+[Flask][] wraps Werkzeug, using it to handle the details of WSGI while
+providing more structure and patterns for defining powerful
+applications.

+
+## A Simple Example
+
+```python
+# save this as app.py
+from werkzeug.wrappers import Request, Response
+
+@Request.application
+def application(request: Request) -> Response:
+    return Response("Hello, World!")
+
+if __name__ == "__main__":
+    from werkzeug.serving import run_simple
+    run_simple("127.0.0.1", 5000, application)
+```
+
+```
+$ python -m app
+  * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
+```

+    multiple values for the same key which is for example used by the parsing
+    functions in the wrappers.  This is necessary because some HTML form
+    elements pass multiple values for the same key.
+
+    :class:`MultiDict` implements all standard dictionary methods.
+    Internally, it saves all values for a key as a list, but the standard dict
+    access methods will only return the first value for a key. If you want to
+    gain access to the other values, too, you have to use the `list` methods as
+    explained below.
+
+    Basic Usage:
+
+    >>> d = MultiDict([('a', 'b'), ('a', 'c')])
+    >>> d
+    MultiDict([('a', 'b'), ('a', 'c')])
+    >>> d['a']
+    'b'
+    >>> d.getlist('a')
+    ['b', 'c']
+    >>> 'a' in d
+    True
+
+    It behaves like a normal dict thus all dict functions will only return the
+    first value when multiple values for one key are found.
+
+    From Werkzeug 0.3 onwards, the `KeyError` raised by this class is also a

+    render a page for a ``400 BAD REQUEST`` if caught in a catch-all for HTTP
+    exceptions.
+

+"""Implements a number of Python exceptions which can be raised from within
+a view to trigger a standard HTTP non-200 response.
+
+Usage Example
+-------------
+
+.. code-block:: python
+
+    from werkzeug.wrappers.request import Request
+    from werkzeug.exceptions import HTTPException, NotFound
+
+    def view(request):
+        raise NotFound()
+
+    @Request.application
+    def application(request):
+        try:
+            return view(request)
+        except HTTPException as e:
+            return e
+
+As you can see from this example those exceptions are callable WSGI
+applications. However, they are not Werkzeug response objects. You
+can get a response object by calling ``get_response()`` on a HTTP
+exception.
+
+Keep in mind that you may have to pass an environ (WSGI) or scope
+(ASGI) to ``get_response()`` because some errors fetch additional
+information relating to the request.
+
+If you want to hook in a different exception page to say, a 404 status
+code, you can add a second except for a specific subclass of an error:
+
+.. code-block:: python
+
+    @Request.application
+    def application(request):
+        try:
+            return view(request)
+        except NotFound as e:
+            return not_found(request)
+        except HTTPException as e:
+            return e

+Application Dispatcher
+======================
+
+This middleware creates a single WSGI application that dispatches to
+multiple other WSGI applications mounted at different URL paths.
+
+A common example is writing a Single Page Application, where you have a
+backend API and a frontend written in JavaScript that does the routing
+in the browser rather than requesting different pages from the server.
+The frontend is a single HTML and JS file that should be served for any
+path besides "/api".
+
+This example dispatches to an API app under "/api", an admin app
+under "/admin", and an app that serves frontend files for all other
+requests::
+
+    app = DispatcherMiddleware(serve_frontend, {
+        '/api': api_app,
+        '/admin': admin_app,
+    })
+
+In production, you might instead handle this at the HTTP server level,
+serving files or proxying to application servers based on location. The
+API and admin apps would each be deployed with a separate WSGI server,
+and the static files would be served directly by the HTTP server.

+    ``headers``:

+X-Forwarded-For Proxy Fix
+=========================
+
+This module provides a middleware that adjusts the WSGI environ based on
+``X-Forwarded-`` headers that proxies in front of an application may
+set.
+
+When an application is running behind a proxy server, WSGI may see the
+request as coming from that server rather than the real client. Proxies
+set various headers to track where the request actually came from.
+
+This middleware should only be used if the application is actually
+behind such a proxy, and should be configured with the number of proxies
+that are chained in front of it. Not all proxies set all the headers.
+Since incoming headers can be faked, you must set how many proxies are
+setting each header so the middleware knows what to trust.

+    """A WSGI middleware which provides static content for development
+    environments or simple server setups. Its usage is quite simple::
+
+        import os
+        from werkzeug.middleware.shared_data import SharedDataMiddleware
+
+        app = SharedDataMiddleware(app, {
+            '/shared': os.path.join(os.path.dirname(__file__), 'shared')
+        })
+
+    The contents of the folder ``./shared`` will now be available on
+    ``http://example.com/shared/``.  This is pretty useful during development
+    because a standalone media server is not required. Files can also be
+    mounted on the root folder and still continue to use the application because
+    the shared data middleware forwards all unhandled requests to the
+    application, even if the requests are below one of the shared folders.
+
+    If `pkg_resources` is available you can also tell the middleware to serve
+    files from package data::
+
+        app = SharedDataMiddleware(app, {
+            '/static': ('myapplication', 'static')
+        })
+
+    This will then serve the ``static`` folder in the `myapplication`
+    Python package.
+
+    The optional `disallow` parameter can be a list of :func:`~fnmatch.fnmatch`
+    rules for files that are not accessible from the web.  If `cache` is set to
+    `False` no caching headers are sent.
+
+    Currently the middleware does not support non-ASCII filenames. If the
+    encoding on the file system happens to match the encoding of the URI it may
+    work but this could also be by accident. We strongly suggest using ASCII
+    only file names for static files.
+
+    The middleware will guess the mimetype using the Python `mimetype`
+    module.  If it's unable to figure out the charset it will fall back
+    to `fallback_mimetype`.
+
+    :param app: the application to wrap.  If you don't want to wrap an
+                application you can pass it :exc:`NotFound`.
+    :param exports: a list or dict of exported files and folders.
+    :param disallow: a list of :func:`~fnmatch.fnmatch` rules.
+    :param cache: enable or disable caching headers.
+    :param cache_timeout: the cache timeout in seconds for the headers.
+    :param fallback_mimetype: The fallback mimetype for unknown files.
+
+    .. versionchanged:: 1.0
+        The default ``fallback_mimetype`` is
+        ``application/octet-stream``. If a filename looks like a text

+"""When it comes to combining multiple controller or view functions
+(however you want to call them) you need a dispatcher. A simple way
+would be applying regular expression tests on the ``PATH_INFO`` and
+calling registered callback functions that return the value then.
+
+This module implements a much more powerful system than simple regular
+expression matching because it can also convert values in the URLs and
+build URLs.
+
+Here a simple example that creates a URL map for an application with
+two subdomains (www and kb) and some URL rules:
+
+.. code-block:: python
+
+    m = Map([
+        # Static URLs
+        Rule('/', endpoint='static/index'),
+        Rule('/about', endpoint='static/about'),
+        Rule('/help', endpoint='static/help'),
+        # Knowledge Base
+        Subdomain('kb', [
+            Rule('/', endpoint='kb/index'),
+            Rule('/browse/', endpoint='kb/browse'),
+            Rule('/browse/<int:id>/', endpoint='kb/browse'),
+            Rule('/browse/<int:id>/<int:page>', endpoint='kb/browse')
+        ])
+    ], default_subdomain='www')
+
+If the application doesn't use subdomains it's perfectly fine to not set
+the default subdomain and not use the `Subdomain` rule factory. The
+endpoint in the rules can be anything, for example import paths or
+unique identifiers. The WSGI application can use those endpoints to get the
+handler for that URL.  It doesn't have to be a string at all but it's
+recommended.
+
+Now it's possible to create a URL adapter for one of the subdomains and
+build URLs:
+
+.. code-block:: python
+
+    c = m.bind('example.com')
+
+    c.build("kb/browse", dict(id=42))
+    'http://kb.example.com/browse/42/'
+
+    c.build("kb/browse", dict())
+    'http://kb.example.com/browse/'
+
+    c.build("kb/browse", dict(id=42, page=3))
+    'http://kb.example.com/browse/42/3'
+
+    c.build("static/about")
+    '/about'
+
+    c.build("static/index", force_external=True)
+    'http://www.example.com/'
+
+    c = m.bind('example.com', subdomain='kb')
+
+    c.build("static/about")
+    'http://www.example.com/about'
+
+The first argument to bind is the server name *without* the subdomain.
+Per default it will assume that the script is mounted on the root, but
+often that's not the case so you can provide the real mount point as
+second argument:
+
+.. code-block:: python
+
+    c = m.bind('example.com', '/applications/example')
+
+The third argument can be the subdomain, if not given the default
+subdomain is used.  For more details about binding have a look at the
+documentation of the `MapAdapter`.
+
+And here is how you can match URLs:
+
+.. code-block:: python
+
+    c = m.bind('example.com')
+
+    c.match("/")
+    ('static/index', {})
+
+    c.match("/about")
+    ('static/about', {})
+
+    c = m.bind('example.com', '/', 'kb')
+
+    c.match("/")
+    ('kb/index', {})
+
+    c.match("/browse/42/23")
+    ('kb/browse', {'id': 42, 'page': 23})
+
+If matching fails you get a ``NotFound`` exception, if the rule thinks
+it's a good idea to redirect (for example because the URL was defined
+to have a slash at the end but the request was missing that slash) it
+will raise a ``RequestRedirect`` exception. Both are subclasses of
+``HTTPException`` so you can use those errors as responses in the
+application.
+
+If matching succeeded but the URL rule was incompatible to the given
+method (for example there were only rules for ``GET`` and ``HEAD`` but
+routing tried to match a ``POST`` request) a ``MethodNotAllowed``
+exception is raised.

+        """The usage is simple: you just pass the match method the current
+        path info as well as the method (which defaults to `GET`).  The
+        following things can then happen:
+
+        - you receive a `NotFound` exception that indicates that no URL is
+          matching.  A `NotFound` exception is also a WSGI application you
+          can call to get a default page not found page (happens to be the
+          same object as `werkzeug.exceptions.NotFound`)
+
+        - you receive a `MethodNotAllowed` exception that indicates that there
+          is a match for this URL but not for the current request method.
+          This is useful for RESTful applications.
+
+        - you receive a `RequestRedirect` exception with a `new_url`
+          attribute.  This exception is used to notify you about a request
+          Werkzeug requests from your WSGI application.  This is for example the
+          case if you request ``/foo`` although the correct URL is ``/foo/``
+          You can use the `RequestRedirect` instance as response-like object
+          similar to all other subclasses of `HTTPException`.
+
+        - you receive a ``WebsocketMismatch`` exception if the only
+          match is a WebSocket rule but the bind is an HTTP request, or
+          if the match is an HTTP rule but the bind is a WebSocket
+          request.
+
+        - you get a tuple in the form ``(endpoint, arguments)`` if there is
+          a match (unless `return_rule` is True, in which case you get a tuple
+          in the form ``(rule, arguments)``)
+
+        If the path info is not passed to the match method the default path
+        info of the map is used (defaults to the root URL if not defined
+        explicitly).
+
+        All of the exceptions raised are subclasses of `HTTPException` so they
+        can be used as WSGI responses. They will all render generic error or
+        redirect pages.
+
+        Here is a small example for matching:
+
+        >>> m = Map([
+        ...     Rule('/', endpoint='index'),
+        ...     Rule('/downloads/', endpoint='downloads/index'),

+        >>> urls = m.bind("example.com", "/")
+        >>> urls.match("/", "GET")
+        ('index', {})
+        >>> urls.match("/downloads/42")
+        ('downloads/show', {'id': 42})
+
+        And here is what happens on redirect and missing URLs:
+
+        >>> urls.match("/downloads")
+        Traceback (most recent call last):
+          ...
+        RequestRedirect: http://example.com/downloads/
+        >>> urls.match("/missing")

+                       method specified on binding.
+        :param return_rule: return the rule that matched instead of just the

+        """Building URLs works pretty much the other way round.  Instead of
+        `match` you call `build` and pass it the endpoint and a dict of
+        arguments for the placeholders.
+
+        The `build` function also accepts an argument called `force_external`
+        which, if you set it to `True` will force external URLs. Per default
+        external URLs (include the server name) will only be used if the
+        target URL is on a different subdomain.
+
+        >>> m = Map([
+        ...     Rule('/', endpoint='index'),
+        ...     Rule('/downloads/', endpoint='downloads/index'),
+        ...     Rule('/downloads/<int:id>', endpoint='downloads/show')
+        ... ])
+        >>> urls = m.bind("example.com", "/")
+        >>> urls.build("index", {})
+        '/'
+        >>> urls.build("downloads/show", {'id': 42})
+        '/downloads/42'
+        >>> urls.build("downloads/show", {'id': 42}, force_external=True)
+        'http://example.com/downloads/42'
+
+        Because URLs cannot contain non ASCII data you will always get
+        bytes back.  Non ASCII characters are urlencoded with the
+        charset defined on the map instance.
+
+        Additional values are converted to strings and appended to the URL as
+        URL querystring parameters:
+
+        >>> urls.build("index", {'q': 'My Searchstring'})
+        '/?q=My+Searchstring'
+
+        When processing those additional values, lists are furthermore
+        interpreted as multiple values (as per
+        :py:class:`werkzeug.datastructures.MultiDict`):
+
+        >>> urls.build("index", {'q': ['a', 'b', 'c']})
+        '/?q=a&q=b&q=c'
+
+        Passing a ``MultiDict`` will also add multiple values:
+
+        >>> urls.build("index", MultiDict((('p', 'z'), ('q', 'a'), ('q', 'b'))))
+        '/?p=z&q=a&q=b'
+
+        If a rule does not exist when building a `BuildError` exception is
+        raised.
+
+        The build method accepts an argument called `method` which allows you
+        to specify the method you want to have an URL built for if you have
+        different methods for the same endpoint specified.
+
+        :param endpoint: the endpoint of the URL to build.
+        :param values: the values for the URL to build.  Unhandled values are
+                       appended to the URL as query parameters.
+        :param method: the HTTP method for the rule if there are different
+                       URLs for different methods on the same endpoint.
+        :param force_external: enforce full canonical external URLs. If the URL
+                               scheme is not provided, this will generate
+                               a protocol-relative URL.
+        :param append_unknown: unknown parameters are appended to the generated
+                               URL as query string argument.  Disable this
+                               if you want the builder to ignore those.
+        :param url_scheme: Scheme to use in place of the bound
+            :attr:`url_scheme`.
+
+        .. versionchanged:: 2.0
+            Added the ``url_scheme`` parameter.

+    that change the way it behaves and are passed to the `Rule` constructor.
+    Note that besides the rule-string all arguments *must* be keyword arguments
+    in order to not break the application on Werkzeug upgrades.
+
+    `string`
+        Rule strings basically are just normal URL paths with placeholders in
+        the format ``<converter(arguments):name>`` where the converter and the
+        arguments are optional.  If no converter is defined the `default`
+        converter is used which means `string` in the normal configuration.
+
+        URL rules that end with a slash are branch URLs, others are leaves.
+        If you have `strict_slashes` enabled (which is the default), all
+        branch URLs that are matched without a trailing slash will trigger a
+        redirect to the same URL with the missing slash appended.
+
+        The converters are defined on the `Map`.
+
+    `endpoint`
+        The endpoint for this rule. This can be anything. A reference to a
+        function, a string, a number etc.  The preferred way is using a string
+        because the endpoint is used for URL generation.
+
+    `defaults`
+        An optional dict with defaults for other rules with the same endpoint.
+        This is a bit tricky but useful if you want to have unique URLs::
+
+            url_map = Map([
+                Rule('/all/', defaults={'page': 1}, endpoint='all_entries'),
+                Rule('/all/page/<int:page>', endpoint='all_entries')
+            ])
+
+        If a user now visits ``http://example.com/all/page/1`` they will be
+        redirected to ``http://example.com/all/``.  If `redirect_defaults` is
+        disabled on the `Map` instance this will only affect the URL
+        generation.
+
+    `subdomain`
+        The subdomain rule string for this rule. If not specified the rule
+        only matches for the `default_subdomain` of the map.  If the map is
+        not bound to a subdomain this feature is disabled.
+
+        Can be useful if you want to have user profiles on different subdomains
+        and all subdomains are forwarded to your application::
+
+            url_map = Map([
+                Rule('/', subdomain='<username>', endpoint='user/homepage'),
+                Rule('/stats', subdomain='<username>', endpoint='user/stats')
+            ])
+
+    `methods`
+        A sequence of http methods this rule applies to.  If not specified, all
+        methods are allowed. For example this can be useful if you want different
+        endpoints for `POST` and `GET`.  If methods are defined and the path
+        matches but the method matched against is not in this list or in the
+        list of another rule for that path the error raised is of the type
+        `MethodNotAllowed` rather than `NotFound`.  If `GET` is present in the
+        list of methods and `HEAD` is not, `HEAD` is added automatically.
+
+    `strict_slashes`
+        Override the `Map` setting for `strict_slashes` only for this rule. If
+        not specified the `Map` setting is used.
+
+    `merge_slashes`
+        Override :attr:`Map.merge_slashes` for this rule.
+
+    `build_only`
+        Set this to True and the rule will never match but will create a URL
+        that can be build. This is useful if you have resources on a subdomain
+        or folder that are not handled by the WSGI application (like static data)
+
+    `redirect_to`
+        If given this must be either a string or callable.  In case of a
+        callable it's called with the url adapter that triggered the match and
+        the values of the URL as keyword arguments and has to return the target
+        for the redirect, otherwise it has to be a string with placeholders in
+        rule syntax::
+
+            def foo_with_slug(adapter, id):
+                # ask the database for the slug for the old id.  this of
+                # course has nothing to do with werkzeug.
+                return f'foo/{Foo.get_slug_for_id(id)}'
+
+            url_map = Map([
+                Rule('/foo/<slug>', endpoint='foo'),
+                Rule('/some/old/url/<slug>', redirect_to='foo/<slug>'),
+                Rule('/other/old/url/<int:id>', redirect_to=foo_with_slug)
+            ])
+
+        When the rule is matched the routing system will raise a
+        `RequestRedirect` exception with the target for the redirect.
+
+        Keep in mind that the URL will be joined against the URL root of the
+        script so don't use a leading slash on the target URL unless you
+        really mean root of that domain.
+
+    `alias`
+        If enabled this rule serves as an alias for another rule with the same
+        endpoint and arguments.
+
+    `host`
+        If provided and the URL map has host matching enabled this can be
+        used to provide a match rule for the whole host.  This also means
+        that the subdomain feature is disabled.
+
+    `websocket`
+        If ``True``, this rule is only matches for WebSocket (``ws://``,
+        ``wss://``) requests. By default, rules will only match for HTTP
+        requests.

+        with ``unix://`` for a Unix socket.
+    :param port: The port to bind to, for example ``8080``. Using ``0``
+        tells the OS to pick a random free port.
+    :param application: The WSGI application to run.
+    :param use_reloader: Use a reloader process to restart the server
+        process when files are changed.

+        in addition to Python modules. For example, watch a
+        configuration file.
+    :param exclude_patterns: The reloader will ignore changes to any
+        files matching these :mod:`fnmatch` patterns. For example,
+        ignore cache files.
+    :param reloader_interval: How often the reloader tries to check for
+        changes.
+    :param reloader_type: The reloader to use. The ``'stat'`` reloader
+        is built in, but may require significant CPU to watch files. The

+    :param request_handler: Use a different
+        :class:`~BaseHTTPServer.BaseHTTPRequestHandler` subclass to
+        handle requests.
+    :param static_files: A dict mapping URL prefixes to directories to
+        serve static files from using
+        :class:`~werkzeug.middleware.SharedDataMiddleware`.
+    :param passthrough_errors: Don't catch unhandled exceptions at the
+        server level, let the server crash instead. If ``use_debugger``

+    :param ssl_context: Configure TLS to serve over HTTPS. Can be an
+        :class:`ssl.SSLContext` object, a ``(cert_file, key_file)``
+        tuple to create a typical context, or the string ``'adhoc'`` to

+    """This class can be used to conveniently create a WSGI environment
+    for testing purposes.  It can be used to quickly create WSGI environments
+    or request objects from arbitrary data.
+
+    The signature of this class is also used in some other places as of
+    Werkzeug 0.5 (:func:`create_environ`, :meth:`Response.from_values`,
+    :meth:`Client.open`).  Because of this most of the functionality is
+    available through the constructor alone.
+
+    Files and regular form data can be manipulated independently of each
+    other with the :attr:`form` and :attr:`files` attributes, but are
+    passed with the same argument to the constructor: `data`.
+
+    `data` can be any of these values:
+
+    -   a `str` or `bytes` object: The object is converted into an
+        :attr:`input_stream`, the :attr:`content_length` is set and you have to
+        provide a :attr:`content_type`.
+    -   a `dict` or :class:`MultiDict`: The keys have to be strings. The values
+        have to be either any of the following objects, or a list of any of the
+        following objects:
+
+        -   a :class:`file`-like object:  These are converted into
+            :class:`FileStorage` objects automatically.
+        -   a `tuple`:  The :meth:`~FileMultiDict.add_file` method is called
+            with the key and the unpacked `tuple` items as positional
+            arguments.
+        -   a `str`:  The string is set as form data for the associated key.
+    -   a file-like object: The object content is loaded in memory and then
+        handled like a regular `str` or a `bytes`.
+
+    :param path: the path of the request.  In the WSGI environment this will
+                 end up as `PATH_INFO`.  If the `query_string` is not defined
+                 and there is a question mark in the `path` everything after
+                 it is used as query string.
+    :param base_url: the base URL is a URL that is used to extract the WSGI
+                     URL scheme, host (server name + server port) and the
+                     script root (`SCRIPT_NAME`).
+    :param query_string: an optional string or dict with URL parameters.
+    :param method: the HTTP method to use, defaults to `GET`.
+    :param input_stream: an optional input stream.  Do not specify this and
+                         `data`.  As soon as an input stream is set you can't
+                         modify :attr:`args` and :attr:`files` unless you
+                         set the :attr:`input_stream` to `None` again.
+    :param content_type: The content type for the request.  As of 0.5 you
+                         don't have to provide this when specifying files
+                         and form data via `data`.
+    :param content_length: The content length for the request.  You don't
+                           have to specify this when providing data via
+                           `data`.
+    :param errors_stream: an optional error stream that is used for
+                          `wsgi.errors`.  Defaults to :data:`stderr`.
+    :param multithread: controls `wsgi.multithread`.  Defaults to `False`.
+    :param multiprocess: controls `wsgi.multiprocess`.  Defaults to `False`.
+    :param run_once: controls `wsgi.run_once`.  Defaults to `False`.
+    :param headers: an optional list or :class:`Headers` object of headers.
+    :param data: a string or dict of form data or a file-object.
+                 See explanation above.
+    :param json: An object to be serialized and assigned to ``data``.
+        Defaults the content type to ``"application/json"``.
+        Serialized with the function assigned to :attr:`json_dumps`.
+    :param environ_base: an optional dict of environment defaults.
+    :param environ_overrides: an optional dict of environment overrides.
+    :param auth: An authorization object to use for the
+        ``Authorization`` header value. A ``(username, password)`` tuple
+        is a shortcut for ``Basic`` authorization.

+        Usually it's a bad idea to call this method without checking the
+        content length first as a client could send dozens of megabytes or more
+        to cause memory problems on the server.
+
+        Note that if the form data was already parsed this method will not
+        return anything as form data parsing does not cache the data like
+        this method does.  To implicitly invoke form data parsing function
+        set `parse_form_data` to `True`.  When this is done the return value
+        of this method will be an empty string if the form parser handles
+        the data.  This generally is not necessary as if the whole data is
+        cached (which is the default) the form parser will used the cached
+        data to parse the form data.  Please be generally aware of checking
+        the content length first in any case before calling this method
+        to avoid exhausting server memory.
+
+        If `as_text` is set to `True` the return value will be a decoded

+    streaming response. A generator is particularly useful for building

+    object is also iterable, although the
+    :func:`~werkzeug.utils.send_file` helper should be used in that
+    case.
+
+    The response object is itself a WSGI application callable. When
+    called (:meth:`__call__`) with ``environ`` and ``start_response``,
+    it will pass its status and headers to ``start_response`` then
