Phase 6 Plan 2: DefaultCoordinationManager Adapter Summary

Implements CoordinationManager with dependency-ordered merging and conflict bounce-back.

Performance

• Duration: 4 min
• Started: 2026-01-30T21:05:00Z
• Completed: 2026-01-30T21:09:00Z
• Tasks: 3
• Files modified: 3
• Tests added: 18

Accomplishments

• Implemented DefaultCoordinationManager adapter with in-memory merge queue
• Dependency-ordered merging via getNextMergeable() and processMerges()
• Priority ordering (high > medium > low) with FIFO within same priority
• Conflict detection and bounce-back task creation
• Agent messaging on conflict via optional MessageRepository
• Comprehensive test coverage (18 tests)

Task Commits

Each task was committed atomically:

1. Task 1: Implement DefaultCoordinationManager - 6d7894b (feat)
2. Task 2: Enhance conflict bounce-back - 4535707 (feat)
3. Task 3: Add comprehensive tests - 37a90db (test)

Files Created/Modified

• src/coordination/manager.ts - DefaultCoordinationManager adapter implementation
• src/coordination/manager.test.ts - 18 tests covering queue, dependencies, conflicts
• src/coordination/index.ts - Exports DefaultCoordinationManager

Decisions Made

• MessageRepository is optional in constructor - conflict messages only created if available
• In-memory queue (same pattern as DispatchManager) - no persistence needed for v1
• System-generated messages use senderType='user' with null senderId

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• DefaultCoordinationManager ready for integration
• All four merge lifecycle events emitted at correct points
• Ready for 06-03-PLAN.md (CLI commands and tRPC procedures for coordination)
