# Phase 5 Plan 3: DispatchManager Port Interface Summary

**DispatchManager port interface with dependency-ordered dispatch and four task lifecycle events**

## Performance

- **Duration:** 3 min
- **Started:** 2026-01-30T20:33:00Z
- **Completed:** 2026-01-30T20:36:00Z
- **Tasks:** 2
- **Files modified:** 4

## Accomplishments

- Created DispatchManager port interface following hexagonal architecture
- Defined QueuedTask type with priority and dependency tracking
- Defined DispatchResult type for dispatch operation outcomes
- Added four dispatch domain events to DomainEventMap

## Task Commits

Each task was committed atomically:

1. **Task 1: Create DispatchManager port interface** - `b2e7c29` (feat)
2. **Task 2: Add dispatch domain events** - `f54ec5e` (feat)

## Files Created/Modified

- `src/dispatch/types.ts` - DispatchManager interface, QueuedTask, DispatchResult types
- `src/dispatch/index.ts` - Public API exports for dispatch module
- `src/events/types.ts` - TaskQueued, TaskDispatched, TaskCompleted, TaskBlocked events
- `src/events/index.ts` - Export new task dispatch event types

## Decisions Made

- **DispatchManager as PORT:** Follows same hexagonal pattern as EventBus, WorktreeManager, AgentManager
- **QueuedTask with dependsOn:** Task dependencies tracked as array of task IDs for dependency-ordered dispatch
- **Four dispatch events:** Mirrors agent lifecycle with queued/dispatched/completed/blocked states

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- DispatchManager interface ready for adapter implementation (05-04)
- Dispatch events ready for event-driven orchestration
- QueuedTask type ready for dependency resolution logic
