+# Phase 14 Plan 02: Phase Lifecycle Events Summary
+
+**Four phase domain events (queued, started, completed, blocked) for parallel phase execution coordination**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-02-02T13:32:00Z
+- **Completed:** 2026-02-02T13:35:00Z
+- **Tasks:** 2
+- **Files modified:** 2
+
+## Accomplishments
+
+- Added PhaseQueuedEvent for tracking phases awaiting execution with dependsOn array
+- Added PhaseStartedEvent for phase execution start notifications
+- Added PhaseCompletedEvent with success flag and optional message
+- Added PhaseBlockedEvent for blocked phases with reason string
+- All events follow existing task event patterns for consistency
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add phase domain events** - `cd02439` (feat)
+2. **Task 2: Export phase events** - `e8ee7f3` (feat)
+
+## Files Created/Modified
+
+- `src/events/types.ts` - Added four phase event interfaces and added them to DomainEventMap union
+- `src/events/index.ts` - Added exports for PhaseQueuedEvent, PhaseStartedEvent, PhaseCompletedEvent, PhaseBlockedEvent
+
+## Decisions Made
+
+- Phase events follow the exact naming pattern of task events (phase:queued mirrors task:queued, etc.)
+- PhaseBlockedEvent uses a simple reason string rather than blockedBy array, matching the simpler pattern appropriate for phase-level blocking
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Phase events ready for use in parallel execution coordination
+- Events follow established patterns and are fully type-safe
+- Ready for 14-03-PLAN.md
