+# Phase 3 Plan 1: Git Events and WorktreeManager Port Summary
+
+**Git domain events and WorktreeManager port interface following hexagonal architecture**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-01-30T18:22:41Z
+- **Completed:** 2026-01-30T18:24:08Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+
+- Added 4 git worktree events to the event system (created, removed, merged, conflict)
+- Created WorktreeManager port interface with 6 methods covering all GIT requirements
+- Established src/git module following same patterns as src/events
+- Full JSDoc documentation for all types and methods
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add git domain events to event types** - `9d7b90b` (feat)
+2. **Task 2: Create WorktreeManager port interface** - `99e4442` (feat)
+
+## Files Created/Modified
+
+**Created:**
+- `src/git/types.ts` - Worktree, WorktreeDiff, MergeResult types and WorktreeManager port interface
+- `src/git/index.ts` - Module exports
+
+**Modified:**
+- `src/events/types.ts` - Added WorktreeCreatedEvent, WorktreeRemovedEvent, WorktreeMergedEvent, WorktreeConflictEvent
+- `src/events/index.ts` - Added exports for new git events
+
+## Decisions Made
+
+- **WorktreeManager as PORT:** Same pattern as EventBus - interface defines contract, implementations (adapters) can be swapped
+- **Four event types:** Cover full lifecycle - create for setup, remove for cleanup, merged for success, conflict for bounce-back
+- **MergeResult.conflicts array:** Enables coordination layer to bounce conflicts back to agents for resolution
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Git events integrated into existing event system
+- WorktreeManager port interface ready for adapter implementation (03-02)
+- Types provide foundation for agent worktree isolation
+- No blockers for continuing
