# PMAT Dogfooding Documentation

This directory contains documentation of PMAT features being dogfooded (used on itself) during development.

## Purpose

"Eating our own dog food" ensures:
- Features work in real-world scenarios
- Developer experience is validated
- Issues are caught before release
- Documentation matches actual usage

## Dogfooding Reports

### Active

- **[v2.139.0-INTEGRATION-SHOWCASE.md](./v2.139.0-INTEGRATION-SHOWCASE.md)** - Complete integration of scaffolding & maintenance system (October 2025)
  - Quality gates configuration
  - Roadmap maintenance validation
  - Health check performance (9.8s, 95% improvement)
  - Git hooks integration
  - All 28 tickets across Sprints 16-20

### Historical

- **[SPRINT-19-DOGFOODING-RESULTS.md](./SPRINT-19-DOGFOODING-RESULTS.md)** - Sprint 19 CLI integration findings (October 2025)
  - Health command timeout issues (led to Sprint 20)
  - Naming convention problems
  - UX improvement opportunities

## Quick Reference

### Commands Dogfooded

```bash
# Quality gates
pmat quality-gates init
pmat quality-gates validate
pmat quality-gates run --report

# Roadmap maintenance
pmat maintain roadmap --validate
pmat maintain roadmap --health
pmat maintain roadmap --fix

# Health checks
pmat maintain health              # 9.8s
pmat maintain health --quick      # 12.5s
pmat maintain health --all        # Full checks

# Git hooks
