+# Phase 14 Plan 07: Unit Tests for Phase Dependencies and Dispatch Summary
+
+**Unit test coverage for PhaseRepository dependency methods and DefaultPhaseDispatchManager queue/dispatch logic with 46 new test cases**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-02-02T12:45:51Z
+- **Completed:** 2026-02-02T12:48:43Z
+- **Tasks:** 2
+- **Files modified:** 3
+
+## Accomplishments
+
+- Added 9 test cases for PhaseRepository dependency methods (createDependency, getDependencies, getDependents)
+- Added 21 test cases for DefaultPhaseDispatchManager covering full dispatch lifecycle
+- Added phase_dependencies table to test database setup for proper test isolation
+- Diamond dependency scenario test verifies correct dispatch ordering
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add PhaseRepository dependency tests** - `26778c6` (test)
+2. **Task 2: Add DefaultPhaseDispatchManager tests** - `1aac486` (test)
+
+## Files Created/Modified
+
+- `src/dispatch/phase-manager.test.ts` - New test file with 21 test cases for phase dispatch manager
+- `src/db/repositories/drizzle/phase.test.ts` - Added 9 test cases for dependency methods
+- `src/db/repositories/drizzle/test-helpers.ts` - Added phase_dependencies table to test schema
+
+## Decisions Made
+
+- Added phase_dependencies table to test-helpers.ts CREATE_TABLES_SQL to enable dependency testing in isolated in-memory databases
+- Tests follow same mock EventBus pattern as existing manager.test.ts for consistency
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Verification
+
+- [x] `npm run build` succeeds without errors
+- [x] `npm test` passes all 452 tests
+- [x] New tests cover all new functionality from 14-01 and 14-04
+
+## Next Phase Readiness
+
+- Phase 14 now has full unit test coverage for phase dependencies and dispatch
+- Ready for plan 14-08 (final plan of phase)
