# PMAT Extreme Integration for Trueno

**Status**: ✅ COMPLETE  
**Date**: 2025-11-23  
**Integration Level**: EXTREME DOGFOODING

## Overview

Trueno now has **full PMAT integration** with O(1) quality gates, comprehensive quality workflows, and continuous improvement tooling. Trueno already had excellent PMAT integration; this upgrade adds **O(1) Quality Gates (Phase 3.4)** and enhanced documentation validation.

## What's New (Phase 3.4 - O(1) Quality Gates)

### 1. O(1) Quality Gates Configuration
- **`.pmat-metrics.toml`** (NEW) - Trueno-specific thresholds for Tier 1/2/3 framework
- **`.pmat-metrics/`** (NEW) - Metric storage directory (trends/, baselines/)
- **Pre-commit hooks** (ENHANCED) - O(1) validation (<30ms) + TDG + bashrs

### 2. O(1) Metrics CI/CD Workflow  
- **`.github/workflows/quality-metrics.yml`** (NEW) - Automatic metric tracking
- Tracks: lint-fast, lint-full, test-tier1, test-tier2, coverage, binary-size, bench
- 30-day trend analysis with ML-based regression prediction
- PR regression warnings with actionable recommendations
- 90-day artifact retention

### 3. Enhanced Documentation Validation
- **`make pmat-validate-docs`** (ENHANCED) - Now generates deep context first
- Validates README.md and CLAUDE.md for hallucinations, broken refs, 404s
- Scientific foundation: Nature 2024, IJCAI 2025

## Existing PMAT Integration (Already Excellent)

- **`.github/workflows/pmat-quality.yml`** (EXISTING) - 8 comprehensive quality jobs
- **11 PMAT Makefile targets** (EXISTING) - Full quality tooling
- **97.7% mutation score** (EXISTING) - EXTREME TDD quality
- **109.3% Rust project score** (EXISTING) - Grade A+

## Rust Project Score: 146.5/134 (109.3%) - Grade A+

**Perfect Scores**:
- ✅ Known Defects: 20/20 (100%)
- ✅ Performance & Benchmarking: 10/10 (100%)
- ✅ Documentation: 15/15 (100%)
- ✅ Dependency Health: 11.5/12 (95.8%)

**Critical Finding**: 25 unwrap() calls (vs 6605 in ruchy - much better!)

## Toyota Way Integration

- **Jidoka**: Automated regression detection at commit time
- **Andon Cord**: Pre-commit blocks on quality violations
- **Kaizen**: Continuous improvement via trend tracking
- **Genchi Genbutsu**: Direct measurement of actual performance
- **Muda**: O(1) validation eliminates slow quality checks

## Thresholds (Trueno-Specific)

From `.pmat-metrics.toml`:
- **lint-fast**: ≤30s (Tier 1 target: sub-second)
- **lint-full**: ≤60s (Tier 2 comprehensive)
- **test-tier1**: ≤5s (Tier 1 focused tests)
- **test-tier2**: ≤5min (Tier 2 full tests + property tests)
- **coverage**: ≤10min (Tier 2 coverage analysis)
- **binary-size**: ≤5MB (lean SIMD library)
- **bench**: ≤10min (Tier 3 benchmarks)

**SIMD-Specific**:
- **min_avx512_speedup**: 2x faster than baseline
- **min_python_speedup**: 10x faster than NumPy

## Usage

```bash
# View metric trends
cd /home/noah/src/trueno
pmat show-metrics --trend

# Check for regressions
pmat predict-quality --all

# Run rust-project-score
pmat rust-project-score

# Validate documentation
make pmat-validate-docs

# Run all PMAT checks
make pmat-all

# Run comprehensive quality gate
make pmat-quality-gate
```

## Files Modified/Created

### NEW (O(1) Quality Gates)
- `.pmat-metrics.toml` - O(1) thresholds
- `.pmat-metrics/` - Metric storage
- `.github/workflows/quality-metrics.yml` - O(1 workflow
- `PMAT-INTEGRATION.md` - This file

### MODIFIED
- `.gitignore` - Added .pmat-metrics/, deep_context.md
- `Makefile` - Enhanced pmat-validate-docs target
- `.git/hooks/pre-commit` - O(1) validation
- `.git/hooks/post-commit` - Baseline auto-update

### EXISTING (Already integrated)
- `.pmat-gates.toml` - TDG configuration
- `.pmat/` - TDG baseline and rules
- `.github/workflows/pmat-quality.yml` - Comprehensive quality workflow
- 11 PMAT Makefile targets

## Next Steps

1. Address 25 unwrap() calls (Sprint 52)
2. Add SAFETY comments to 334 unsafe blocks (Sprint 52)
3. Run Miri validation: `cargo +nightly miri test` (Sprint 52)

## Conclusion

Trueno now has **EXTREME PMAT integration** with:
- O(1) quality gates (<30ms pre-commit) - NEW
- Automatic CI/CD metric tracking - NEW
- Comprehensive PMAT workflow (8 jobs) - EXISTING
- 97.7% mutation score - EXISTING
- 109.3% Rust project score (Grade A+) - EXISTING
- Enhanced documentation validation - ENHANCED

**Status**: EXTREME INTEGRATION COMPLETE ✅
