# Compact Status - 2025-11-28

**Focus**: Fix Issue #28 graph corruption + spawn burst protection

**Key Accomplishments**:
1. Fixed CRITICAL Issue #28: Deep copy in `wouldCreateCycle()` prevents graph corruption
2. Implemented settling workers tracking (15s window) to prevent spawn overload
3. Tuned spawn delay to 1000ms for stability
4. Closed resolved issues #16 and #17
5. Ran comprehensive code review (8 sub-agents)

**Critical Decisions**:
- Deep copy for cycle detection (simple, correct, no perf impact)
- Optional `recordSpawn?()` for backwards compatibility
- 1000ms spawn delay (tested 50ms → 10000ms → 1000ms)

**Next Priority Actions**:
1. Push branch and create PR
2. Merge after approval, close Issue #28
3. Add tests for settling workers feature

**Critical Issues**:
- Issue #28 fixed (pending merge)
- Code review: 4 blocking items identified (optional interface, missing tests, etc.)

**Key Files Modified**:
- `src/core/dependency-graph.ts` - Deep copy fix
- `tests/unit/core/dependency-graph.test.ts` - 3 regression tests
- `src/implementations/resource-monitor.ts` - Settling workers tracking
- `src/core/configuration.ts` - Spawn delay 50ms → 1000ms
- `src/services/handlers/worker-handler.ts` - Call recordSpawn()

**Context Notes**:
Branch `fix/issue-28-graph-corruption-shallow-copy` has 2 commits ready for PR. Session experienced crashes due to spawn burst - resolved with settling workers + increased delay. Never run `npm test` in Claude Code - use grouped tests instead.
