# Compact Status - 2025-11-28

**Focus**: Issue #28 deep copy fix + 11 code review improvements

**Key Accomplishments**:
1. Fixed CRITICAL graph corruption bug in `wouldCreateCycle()` - shallow copy was mutating original graph
2. Implemented all 11 should-fix items from code review (interface fixes, config, tests, docs)
3. Fixed flaky CI test and npm audit vulnerabilities

**Critical Decisions**:
- Deep copy pattern: `new Map(Array.from(map.entries()).map(([k, v]) => [k, new Set(v)]))`
- Made `recordSpawn()` required (not optional) for ISP compliance
- Configurable settling window via `WORKER_SETTLING_WINDOW_MS`

**Next Priority Actions**:
1. Consider implementing threshold event features (3 TODOs in tests)
2. Prepare v0.3.1 release with release notes
3. Review remaining tech debt in Issue #31

**Critical Issues**:
- All critical issues resolved this session
- 3 pending TODOs for threshold events (enhancement, not blocker)

**Key Files Modified**:
- `src/core/dependency-graph.ts` - Deep copy fix
- `src/core/interfaces.ts` - recordSpawn() required
- `src/implementations/resource-monitor.ts` - Settling window config
- `tests/fixtures/factories.ts` - Complete ConfigFactory
- `docs/FEATURES.md` - Settling workers docs

**Context Notes**:
Graph corruption was caused by shallow copying `Map<string, Set<string>>` - the Set values are references that get mutated. Settling workers tracking prevents spawn burst overload by accounting for workers not yet reflected in load average. All work merged to main via PR #32.
