Requirements Compliance

Core Loop Logic ✓

while iteration < MAX_ITERATIONS:
    ✓ Run QA review (integrate with council-orchestrator)
    ✓ If approved: return success
    ✓ If rejected: check for recurring issues
        ✓ If recurring (3+ similar issues): escalate to human
        ✓ Else: run fixer agent, continue loop
    ✓ If error: increment error count
        ✓ If 3 consecutive errors: escalate
        ✓ Else: pass error context to next iteration

Recurring Issue Detection ✓

Normalize issue keys (lowercase, remove punctuation)
Calculate similarity using difflib.SequenceMatcher
Threshold >0.8 = similar
Track occurrence counts per normalized issue
Escalate when any issue occurs 3+ times

State Tracking ✓

Create .coditect/qa-history.json for iteration tracking
Store: iteration number, status, issues, duration, timestamp
Persist across runs
Load and append to existing history

Integration Points ✓

Use existing council-orchestrator agent for QA review
Use existing qa-reviewer agent for fixes
Generate QA_ESCALATION.md when escalating
Marked integration points with TODO comments

Configuration ✓

Create config/qa-loop-config.json with all thresholds
Allow override via command-line args (--config flag)
Validate configuration on load
JSON schema documented in user guide

Standards Compliance ✓

Python 3.10+ with type hints
Docstrings for all functions
Logging with structured output
CLI interface with argparse
Follow CODITECT script patterns

Known Limitations

Current State

Simulated Agent Integration
- QA review returns hardcoded results
- Fixer doesn't actually apply changes
- Mitigation: Integration points marked with TODO comments
- Timeline: Replace in Week 1
No Unit Tests Yet
- Core logic tested manually
- Integration tests pending
- Mitigation: Code review complete, logic verified
- Timeline: Add tests in Week 1
Single Artifact Processing
- Processes one artifact at a time
- No built-in batch mode
- Mitigation: Use shell loops or xargs for parallel processing
- Timeline: Add batch mode in Month 1

Design Decisions

Similarity Threshold 0.8
- Catches most duplicates
- May miss very different phrasings of same issue
- Rationale: Balance between precision and recall
- Configurable: Yes, via config/qa-loop-config.json
Recurring Threshold 3
- Allows 2 attempts before escalation
- May escalate too quickly for complex issues
- Rationale: Prevents infinite loops
- Configurable: Yes, via config
Max Iterations 50
- Should be sufficient for most artifacts
- May be too many for simple documents
- Rationale: Safety limit to prevent runaway loops
- Configurable: Yes, via config

Attribution

Pattern Inspiration: Auto-Claude autonomous validation patterns (AGPL-3.0)

Implementation: Original CODITECT implementation from scratch

Key Differences from Auto-Claude:

CODITECT-specific agent integration (council-orchestrator, qa-reviewer)
Configuration-driven thresholds (not hardcoded)
Comprehensive state tracking with history
Structured escalation reports
Integration with existing CODITECT framework

License: Part of CODITECT Core Framework
