## 🎉 Latest Achievements

### Sprint 70: cargo-mutants Integration (COMPLETE ✅ - 100%)
**Status**: Production-ready, ready for v2.181.0 release

**Progress**: 7/7 phases complete (100%)

**Completed**:
- ✅ **Phase 1 (PMAT-070-001)**: CargoMutantsWrapper infrastructure
  - Subprocess wrapper for cargo-mutants execution
  - Version detection and validation (v24.7.0+)
  - 10 tests (100% passing)
  - Duration: ~3 hours

- ✅ **Phase 2 (PMAT-070-002)**: JSON parsing and outcome mapping
  - Serde-based JSON parser (289 lines)
  - Outcome mapping: caught→Killed, missed→Survived, timeout→Timeout, unviable→CompileError
  - Utility methods: mutation_score(), count_by_outcome()
  - 9 tests (100% passing)
  - Duration: ~2 hours
  - **FIXED in Session 4**: Parser rewritten for actual v25.3.1 format

- ✅ **Phase 3 (PMAT-070-003)**: CLI Integration - `pmat mutate --use-cargo-mutants`
  - cargo_mutants_backend handler (189 lines)
  - Extended MutateArgs with 5 cargo-mutants flags
  - Config struct pattern (CargoMutantsConfig)
  - Color-coded statistics display (green/yellow/red)

**Session 4 Critical Fix** (October 29, 2025):
- **Issue**: Phase 2 parser designed for assumed JSON format, not actual cargo-mutants v25.3.1
- **Fix**: Complete parser rewrite for actual format (reads `outcomes.json` from directory)

- Clippy Warnings: 0
- Code Size: 8,532+ lines (800 implementation + 2,565 tests + 5,167 docs)
- Extreme TDD: RED → GREEN → REFACTOR → FIX → VERIFY → COMMIT
- Performance: 100x faster than requirements (<1ms vs 100ms target)

**End-to-End Validation** ✅:
```bash
$ pmat mutate --target . --use-cargo-mutants --timeout 10
