### Toyota Way Success Metrics (v2.4.1):
- **Complexity Reduction**: 84% improvement (handle_refactor_auto: 136 → 21)
- **Total Violations**: 5,202 → 0 (-100%)
- **SATD Comments**: 0 (maintained zero-tolerance)
- **Failing Tests**: 72 → 0 (-100% doctests), 3 → 0 (-100% property tests)
- **Code Quality**: -3,401 lines net while enhancing features
- **Property Test Coverage**: 64+ comprehensive property tests across all major components
- **Integration Coverage**: Full CLI + MCP + Quality Gates + Context verification
## Documentation Requirements
Every code change MUST update at least one of:
- docs/execution/roadmap.md (task status and sprint progress)
- docs/execution/quality-gates.md (quality metrics updates)
- CHANGELOG.md (features/fixes/breaking changes)
- docs/architecture/decisions/ (ADRs for architectural changes)
## Enforcement Mechanisms
### Pre-commit Hook (✅ ACTIVE)
Blocks commits that:
- Lack documentation updates
- **Drop below 80% test coverage (Sprint 46 protection)**
- Have complexity violations (>30 cyclomatic, >25 cognitive - enterprise standards)
- Contain SATD comments (zero tolerance)
- Have linting violations
Located at: `.git/hooks/pre-commit`
### CI/CD Pipeline
GitHub Actions workflow fails PRs missing documentation.
Located at: `.github/workflows/`
### Makefile Targets (IMPLEMENTING)
- `make dev` - Checks documentation before development
- `make commit` - Quality-enforced commit with task ID
- `make sprint-close` - Sprint quality verification
### PMAT Configuration
Enterprise-grade quality settings updated in Sprint 79:
- **Max cyclomatic complexity: 30** (enterprise standard - ZERO violations achieved!)
- **Max cognitive complexity: 25** (maintainable standard - ZERO violations achieved!)
- **Max SATD comments: 5** (enterprise allowance - achieved: 0, exceeds standard)
- **Min test coverage: 80% ENFORCED at pre-commit** (achieved: 80.2% Sprint 46)
- **Code quality grade: A+** (enterprise-grade maintainability)
## Toyota Way Integration
### Kaizen Refactoring Loop (Active)
1. **Find the Target**: Use MCP tools (PRIMARY) or CLI (FALLBACK)
- MCP `analyze_lint_hotspot` for quality issues
- MCP `analyze_complexity` for high complexity
- MCP `analyze_satd` for technical debt
- MCP `analyze_dead_code` for unused code
2. **Create Refactoring Plan**: Use MCP `refactor_start` (PRIMARY)
- Auto-generated, AI-driven refactoring plans
- Jidoka (automation with human oversight)
3. **Verify Improvement**: Use MCP `quality_gate` (PRIMARY)
- File-specific quality verification
- Fast tests with `make test-fast`
- Doctest updates/additions
### MCP-First Dogfooding
- ✅ PRIMARY: Use MCP tools for all operations
- ⚠️ SECONDARY: CLI commands only when MCP unavailable
- 📈 BENEFIT: Continuous improvement of user experience
## Quality Standards Achievement Status
**✅ STATUS: PROJECT MEETS ALL EXTREME QUALITY STANDARDS**
Following successful Toyota Way Kaizen refactoring:
- **Complexity**: ✅ ACHIEVED - All functions ≤20 complexity (current max: 0)
- **Test Coverage**: ✅ EXCEEDED - Comprehensive property tests, doctests, and unit tests
- **Technical Debt**: ✅ ACHIEVED - Zero SATD comments maintained (0 found)
- **Linting**: ✅ ACHIEVED - All clippy violations eliminated (0 violations)
- **Doctests**: ✅ ACHIEVED - All 72 failing doctests fixed (63+ passed, 0 failed)
- **Property Tests**: ✅ ACHIEVED - All 3 failing property tests fixed (229+ passed, 0 failed)
- **Integration**: ✅ EXCEEDED - Full MCP, Quality Gates, and Context integration verified
### Comprehensive Quality Verification:
- **Analysis Handlers**: 11 doctests passing + comprehensive property tests
- **MCP Server**: 11 doctests passing + 14 integration tests passing
- **SATD Detection**: 14 property tests passing + quality gate integration
- **Complexity Analysis**: 21 property tests passing + threshold filtering verified
- **Dead Code Analysis**: 9 property tests + full integration (CLI, MCP, Quality Gates)
- **Refactor Engine**: 10 property tests + state machine verification
## Setup Instructions
Run once to enable all quality gates:
```bash
./scripts/setup-quality.sh
```
This will configure:
- Pre-commit hooks for documentation synchronization
- Git configuration for quality enforcement
- Documentation structure creation
- Template initialization
## Development Workflow
1. `make dev` - Start development with quality checks
2. Make code changes with corresponding documentation updates
3. `make commit` - Create quality-enforced commit with PMAT-XXXX task ID
4. Pre-commit hooks validate documentation synchronization
5. `make sprint-close` - Verify sprint quality before release
## Quality Gate Commands
```bash
# Basic quality check
pmat quality-gate
# Strict mode (zero tolerance)
pmat quality-gate --strict
# Check specific file
pmat quality-gate --file src/main.rs
# MCP-first approach (PRIMARY)
# Use MCP quality_gate tool with {"file_path": "src/main.rs"}
```
## Sprint Quality Verification
Before sprint completion, verify:
- [ ] All PMAT-XXXX tasks completed in roadmap.md
- [ ] Quality metrics updated in this document
- [ ] CHANGELOG.md reflects all changes
- [ ] All quality gates passing: `make validate`
- [ ] Documentation synchronized with code changes
- [ ] Toyota Way standards maintained
