# Compact Status - 04-10-2025

**Focus**: Post-PR review fixes - resolved all CRITICAL security and architecture issues

**Key Accomplishments**:
- ✅ Fixed fork-bomb vulnerability (stale task detection + spawn burst protection)
- ✅ Resolved all security vulnerabilities (command injection, path traversal, dependency updates)
- ✅ Decoupled architecture (WorkerHandler 7→4 dependencies, removed circular deps)
- ✅ Added performance monitoring (EventBus handler profiling with 100ms warnings)
- ✅ Created comprehensive event flow documentation with ASCII diagrams

**Critical Decisions**:
- **50ms spawn delay**: Prevents fork-bomb from burst spawning (reduced from 100ms, DO NOT REMOVE)
- **30-min stale threshold**: Balances legitimate restarts vs crashed tasks (see RecoveryManager JSDoc)
- **Handler profiling**: Automatic warnings for slow handlers (>100ms) - replaced p-limit throttling approach
- **Worktree default false**: Opt-in for experimental feature (safer for new users)

**Next Priority Actions**:
- [ ] Run full test suite (`npm test`) to verify all changes
- [ ] Fix any test failures from architecture refactoring
- [ ] Create worktree-manager.test.ts (500-600 lines needed)
- [ ] Create github-integration.test.ts (300-400 lines needed)
- [ ] Commit changes and create PR to merge to main

**Critical Issues**:
- ⚠️ **Missing comprehensive tests**: worktree-manager and github-integration need full test coverage
- ⚠️ **Uncommitted changes**: 30 files modified, need atomic commits before PR

**Key Files Modified**:
- `src/services/recovery-manager.ts` - Added 30-min stale task detection (lines 88-175)
- `src/services/handlers/worker-handler.ts` - Added 50ms spawn burst protection (lines 21-63)
- `src/services/worktree-manager.ts` - Command injection sanitization for git ops
- `src/utils/validation.ts` - Path traversal protection with fs.realpathSync()
- `src/core/events/event-bus.ts` - Handler profiling with timing metrics (lines 157-211)
- `docs/architecture/EVENT_FLOW.md` - **NEW** - Comprehensive event flow documentation
- `package.json` - Updated deps: @modelcontextprotocol/sdk (1.19.1), better-sqlite3 (12.4.1)

**Context Notes**:
This session resolved a fork-bomb discovered on 2025-10-04 when testing spawn delay removal. The issue required TWO fixes: (1) stale task detection in recovery, and (2) spawn burst protection. Both are now documented with DO NOT REMOVE warnings and comprehensive JSDoc explaining the incident and alternatives. All CRITICAL security issues (command injection, path traversal) have been resolved. Branch is ready for testing and PR creation.

**Build Status**: ✅ `npm run build` succeeds
**Vulnerabilities**: ✅ 0 remaining (all fixed via npm audit fix)
**Branch**: `test/comprehensive-testing` (30 files modified, uncommitted)
