## 🎉 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
