+# Pull Request: QC Orchestrator Implementation
+
+## Overview
+This PR implements a fully functional QC (Quality Control) orchestrator feature that can be invoked via the `/qc` slash subcommand from the Rust CLI, with future support planned for the Tauri GUI.
+
+## What's New
+
+### 🎯 Main Feature: QC Orchestrator
+A production-ready quality control system that automates testing, diff analysis, risk assessment, and PR recommendations.
+
+```bash
+# Quick check
+codex qc --feature "Your feature description" --profile minimal
+
+# Standard validation
+codex qc --feature "Your feature description" --profile standard
+
+# Comprehensive testing
+codex qc --feature "Your feature description" --profile full
+```
+
+### 📊 Key Capabilities
+- **Automated Testing**: Executes Rust tests, Clippy, and web tests based on profile
+- **Git Integration**: Analyzes diffs using git2 library
+- **Risk Scoring**: Calculates risk (0.0-1.0) from test results and diff size
+- **200-Line Rule**: Auto-recommends PR creation for large changes
+- **Smart Logging**: Writes markdown logs to `_docs/logs/` with full details
+

+
+## Architecture
+
+### Type System
+- **TestProfile**: Minimal | Standard | Full
+- **QcConfig**: Configuration with defaults
+- **QcInput**: User inputs (feature, agent, AI, profile)
+- **DiffStats**: Git diff statistics
+- **CommandStatus**: NotRun | Passed | Failed
+- **TestResult**: Individual test outcomes
+- **Recommendation**: MergeOk | NeedsFix | CreatePrForReview
+- **QcResult**: Complete QC analysis results
+
+### Key Functions
+- `run_qc()`: Main orchestration entry point
+- `compute_diff_stats()`: Git diff analysis via git2
+- `run_tests()`: Execute test suite based on profile
+- `compute_risk_score()`: Calculate risk from test results
+- `build_recommendation()`: Decision logic for recommendations
+- `write_log()`: Generate markdown logs
+
+## Testing
+
+### Unit Tests (5)
+✅ Profile parsing and string conversion  
+✅ Recommendation formatting  
+✅ Risk score calculation  
+✅ Recommendation logic with various scenarios  
+
+### Integration Tests (4)
+✅ Full QC execution with git repository  
+✅ Profile parsing via FromStr trait  
+✅ Default configuration validation  
+✅ End-to-end orchestrator flow  
+
+### Self-Validation
+The QC orchestrator successfully validated itself:
+- **Result**: CreatePrForReview
+- **Reason**: 423 lines changed (exceeds 200-line rule)
+- **Tests**: All passed
+- **Risk**: 0.20 (low-medium)
+
+## Dependencies Added
+- `git2` (0.18) - Git repository operations
+- `chrono` (0.4) - Timezone-aware timestamps
+- `clap` (4.5) - CLI argument parsing
+- `anyhow` (1.0) - Error handling
+- `tempfile` (3.10) - Test fixtures (dev-only)
+
+## Compatibility
+✅ Rust 2024 edition  
+✅ Compatible with existing codebase  
+✅ Auto-detects `codex-rs` directory  
+✅ Gracefully handles missing tools  
+✅ Ready for Tauri GUI integration  
+
+## Documentation
+- **User Guide**: `codex-rs/_docs/qc-orchestrator.md`
+- **Implementation Summary**: `QC_IMPLEMENTATION_SUMMARY.md`
+- **Inline Documentation**: Comprehensive rustdoc comments
+- **Example Logs**: `_docs/logs/2025-11-19-*.md`
+
+## Breaking Changes
