 - 14-03: PhaseDispatchManager methods use Phase suffix (queuePhase, completePhase) for clarity
 - 14-03: QueuedPhase includes initiativeId for context association
 - 14-03: PhaseDispatchResult simpler than DispatchResult (no agentId field)
+- 14-04: In-memory Map for phaseQueue (same pattern as DefaultDispatchManager)
+- 14-04: Dependency checking via phaseRepository.findById for status
+- 14-04: Sort ready phases by queuedAt (oldest first, no priority like tasks)
 - 14-05: PhaseDispatchManager optional in context following existing pattern
 - 14-05: createPhaseDependency validates both phases exist before creating dependency
 - 14-05: getPhaseDependencies returns { dependencies: string[] } wrapper for API consistency

+# 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)
