+# Phase 6 Plan 1: Coordination Domain Events & Port Interface Summary
+
+**Four merge lifecycle events and CoordinationManager port interface following hexagonal architecture patterns.**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-01-30T20:02:23Z
+- **Completed:** 2026-01-30T20:04:07Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+- Added four coordination events to DomainEventMap (MergeQueued, MergeStarted, MergeCompleted, MergeConflicted)
+- Created CoordinationManager port interface with full queue management methods
+- Established merge coordination types (MergeQueueItem, MergeStatus, MergeResult)
+- Maintained hexagonal architecture pattern consistency
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add coordination domain events** - `94130a6` (feat)
+2. **Task 2: Create CoordinationManager port interface** - `0570d21` (feat)
+
+## Files Created/Modified
+- `src/events/types.ts` - Added MergeQueuedEvent, MergeStartedEvent, MergeCompletedEvent, MergeConflictedEvent
+- `src/events/index.ts` - Exported new merge events
+- `src/coordination/types.ts` - Created CoordinationManager port interface and domain types
+- `src/coordination/index.ts` - Module exports following existing patterns
+
+## Decisions Made
+- MergeResult type mirrors git MergeResult but includes taskId for coordination-level tracking
+- Events use `merge:` prefix to clearly distinguish from `worktree:` events which are lower-level git operations
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- CoordinationManager interface ready for adapter implementation
+- Events ready for emission during merge operations
+- Ready for 06-02-PLAN.md (InMemoryCoordinationManager adapter)
