+# Phase 14 Plan 08: E2E Tests for Phase Dispatch Summary
+
+**E2E tests for parallel phase execution with dependency ordering, covering independent dispatch, sequential dependencies, diamond patterns, and blocked phases**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-02-02T13:47:00Z
+- **Completed:** 2026-02-02T13:50:00Z
+- **Tasks:** 2
+- **Files modified:** 2
+
+## Accomplishments
+
+- Added phaseDispatchManager to TestHarness wired with phaseRepository and eventBus
+- Created 5 E2E tests covering parallel phase execution scenarios
+- Verified independent phases dispatch in parallel
+- Verified dependent phases wait for prerequisites
+- Verified diamond dependency pattern (A -> B,C -> D)
+- Verified blocked phases prevent dispatch and propagate down chain
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 2: Add phaseDispatchManager to TestHarness** - `38ee2d1` (feat)
+2. **Task 1: Create phase dispatch E2E tests** - `03fefd8` (test)
+
+## Files Created/Modified
+
+- `src/test/harness.ts` - Added phaseDispatchManager property and wiring
+- `src/test/e2e/phase-dispatch.test.ts` - New E2E test file with 5 tests
+
+## Decisions Made
+
+- PhaseDispatchManager added to TestHarness following exact pattern of DispatchManager
+- E2E tests use direct repository/manager calls rather than fixtures (phases created inline for clarity)
+
+## 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 (including 5 new E2E tests)
+- [x] E2E tests verify actual parallel behavior
+
+## Next Phase Readiness
+
+- Phase 14 parallel execution complete
+- All E2E tests pass
+- Ready for Phase 15 (Frontend Wireframes)
