# Compact Status - 01-10-2025

**Focus**: Test infrastructure cleanup and critical runtime crash prevention

**Key Accomplishments**:
- ✅ Fixed EventBus test infrastructure (44/44 tests now passing, was 0/44)
- ✅ Prevented production crash in TaskManager.retry() from null handling bug
- ✅ Removed flaky fake timer tests, replaced with reliable real timers
- ✅ Updated QueryHandler API to gracefully return null (not throw) for not-found tasks
- ✅ Improved overall test pass rate to 80.2% (421/525 passing)

**Critical Decisions**:
- **Return null for not-found tasks**: More ergonomic API, clearer semantics, allows distinguishing "not found" from "database error"
- **Remove fake timers**: Real timers with SHORT constants (100ms) are faster, more reliable, less brittle
- **Use test factories**: Enforces TEST_STANDARDS.md, improves maintainability, DRY principle

**Next Priority Actions**:
- [ ] Fix query handler schema mismatches (status: 'pending' vs 'queued' - 11 test failures)
- [ ] Fix output capture API mismatch (startCapture method doesn't exist - 3 failures)
- [ ] Fix database schema test failures (various database tests)
- [ ] Implement 9 integration test scenarios from TEST_STANDARDS.md
- [ ] Reach 85/100 test quality score (currently 75/100)

**Critical Issues**:
- **RESOLVED**: TaskManager.retry() null handling crash (fixed in commit f3acb7c)
- **RESOLVED**: EventBus logger null reference (fixed in commit f3acb7c)
- **None remaining** - All critical blockers resolved

**Key Files Modified**:
- `src/services/handlers/query-handler.ts` - Return null for not-found (8 lines)
- `src/services/task-manager.ts` - Added null handling to retry() and getStatus() (18 lines)
- `tests/unit/core/events/event-bus-request.test.ts` - Fixed constructor, removed fake timers (94 lines)
- `tests/unit/core/events/event-bus.test.ts` - Fixed constructor, cleanup, expectations (37 lines)
- `tests/unit/services/handlers/query-handler.test.ts` - Updated API expectations (65 lines)

**Context Notes**:
This session prevented a production-level bug from shipping. The pre-commit review agent caught an unsafe type assertion in TaskManager.retry() that would crash with `TypeError: Cannot read property 'status' of null` when users tried to retry non-existent tasks. All changes are committed (f3acb7c) and the branch is clean. EventBus infrastructure is now rock-solid (100% test pass rate).

**Test Status**: 421/525 passing (80.2%), EventBus: 44/44 (100%)

**Branch**: test/comprehensive-testing (clean)
