# Dependency graph
requires:
  - phase: 05
    provides: DefaultDispatchManager adapter pattern
  - phase: 14-01
    provides: Phase dependencies schema and repository methods
  - phase: 14-02
    provides: Phase lifecycle events (queued, started, completed, blocked)
  - phase: 14-03
    provides: PhaseDispatchManager port interface
provides:
  - DefaultPhaseDispatchManager adapter with in-memory queue
  - Dependency-ordered phase dispatch
  - Phase event emission for all lifecycle operations
affects: [14-parallel-phase-execution]

# Tech tracking

  added: []
  patterns:
    - In-memory Map for phase queue (same as task dispatch)
    - Dependency checking via repository lookup

key-decisions:
  - "In-memory Map for phaseQueue (same pattern as DefaultDispatchManager)"
  - "Dependency checking via phaseRepository.findById for status"
  - "Sort ready phases by queuedAt (oldest first, no priority like tasks)"

patterns-established:
  - "Phase dispatch adapter mirrors task dispatch adapter structure"
  - "Constructor takes PhaseRepository and EventBus (not AgentManager like tasks)"

# Phase 14 Plan 04: DefaultPhaseDispatchManager Adapter Summary

**In-memory phase dispatch adapter with dependency-ordered queue and full lifecycle event emission following DefaultDispatchManager patterns**

## Performance

- **Duration:** 2 min
- **Started:** 2026-02-02T13:39:00Z
- **Completed:** 2026-02-02T13:41:00Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments

- Created DefaultPhaseDispatchManager class implementing PhaseDispatchManager interface
- In-memory phaseQueue (Map) and blockedPhases (Map) for state management
- Dependency checking via phaseRepository.getDependencies() and status lookup
- Full event emission: PhaseQueuedEvent, PhaseStartedEvent, PhaseCompletedEvent, PhaseBlockedEvent
- Exported adapter from dispatch module for public consumption

## Task Commits

Each task was committed atomically:

1. **Task 1: Implement DefaultPhaseDispatchManager** - `1ba9587` (feat)
2. **Task 2: Export DefaultPhaseDispatchManager** - `053168f` (feat)

## Files Created/Modified

- `src/dispatch/phase-manager.ts` - Full adapter implementation with 6 interface methods plus private helper
- `src/dispatch/index.ts` - Added export for DefaultPhaseDispatchManager class

## Decisions Made

- In-memory Map for queue (same pattern as DefaultDispatchManager, no persistence needed for v1)
- Dependency checking via phaseRepository.findById to check status === 'completed'
- Ready phases sorted by queuedAt (oldest first) - no priority field unlike tasks
- Constructor takes only PhaseRepository and EventBus (simpler than DefaultDispatchManager which also needs AgentManager, TaskRepository, MessageRepository)

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- DefaultPhaseDispatchManager ready for integration testing
- All interface methods implemented with consistent event emission
- Ready for 14-05-PLAN.md (phase dispatch integration or CLI commands)
