Move src/ → apps/server/ and packages/web/ → apps/web/ to adopt standard monorepo conventions (apps/ for runnable apps, packages/ for reusable libraries). Update all config files, shared package imports, test fixtures, and documentation to reflect new paths. Key fixes: - Update workspace config to ["apps/*", "packages/*"] - Update tsconfig.json rootDir/include for apps/server/ - Add apps/web/** to vitest exclude list - Update drizzle.config.ts schema path - Fix ensure-schema.ts migration path detection (3 levels up in dev, 2 levels up in dist) - Fix tests/integration/cli-server.test.ts import paths - Update packages/shared imports to apps/server/ paths - Update all docs/ files with new paths

# Dispatch & Events
|
|
|
|
`apps/server/dispatch/` — Task and phase dispatch queues. `apps/server/events/` — Typed event bus.
|
|
|
|
## Event Bus
|
|
|
|
`apps/server/events/` — Typed pub/sub system for inter-module communication.
|
|
|
|
### Architecture
|
|
- **Port**: `EventBus` interface with `emit(event)` and `on(type, handler)`
|
|
- **Adapter**: `TypedEventBus` using Node.js `EventEmitter`
|
|
- All events implement `BaseEvent { type, timestamp, payload }`
|
|
|
|
### Event Types (52)
|
|
|
|
| Category | Events | Count |
|
|
|----------|--------|-------|
|
|
| **Agent** | `agent:spawned`, `agent:stopped`, `agent:crashed`, `agent:resumed`, `agent:account_switched`, `agent:deleted`, `agent:waiting`, `agent:output` | 8 |
|
|
| **Task** | `task:queued`, `task:dispatched`, `task:completed`, `task:blocked`, `task:pending_approval` | 5 |
|
|
| **Phase** | `phase:queued`, `phase:started`, `phase:completed`, `phase:blocked` | 4 |
|
|
| **Merge** | `merge:queued`, `merge:started`, `merge:completed`, `merge:conflicted` | 4 |
|
|
| **Page** | `page:created`, `page:updated`, `page:deleted` | 3 |
|
|
| **Process** | `process:spawned`, `process:stopped`, `process:crashed` | 3 |
|
|
| **Server** | `server:started`, `server:stopped` | 2 |
|
|
| **Worktree** | `worktree:created`, `worktree:removed`, `worktree:merged`, `worktree:conflict` | 4 |
|
|
| **Account** | `account:credentials_refreshed`, `account:credentials_expired`, `account:credentials_validated` | 3 |
|
|
| **Preview** | `preview:building`, `preview:ready`, `preview:stopped`, `preview:failed` | 4 |
|
|
| **Conversation** | `conversation:created`, `conversation:answered` | 2 |
|
|
| **Log** | `log:entry` | 1 |
|
|
|
|
### Key Event Payloads
|
|
|
|
```typescript
|
|
AgentSpawnedEvent { agentId, name, taskId, worktreeId, provider }
|
|
AgentStoppedEvent { agentId, name, taskId, reason }
|
|
// reason: 'user_requested'|'task_complete'|'error'|'waiting_for_input'|
|
|
// 'context_complete'|'plan_complete'|'detail_complete'|'refine_complete'
|
|
AgentWaitingEvent { agentId, name, taskId, sessionId, questions[] }
|
|
AgentOutputEvent { agentId, stream, data }
|
|
TaskCompletedEvent { taskId, agentId, success, message }
|
|
TaskQueuedEvent { taskId, priority, dependsOn[] }
|
|
PhaseStartedEvent { phaseId, initiativeId }
|
|
MergeConflictedEvent { taskId, agentId, worktreeId, targetBranch, conflictingFiles[] }
|
|
AccountCredentialsRefreshedEvent { accountId, expiresAt, previousExpiresAt? }
|
|
```
|
|
|
|
## Task Dispatch
|
|
|
|
`apps/server/dispatch/` — In-memory queue with dependency-ordered dispatch.
|
|
|
|
### Architecture
|
|
- **Port**: `DispatchManager` interface
|
|
- **Adapter**: `DefaultDispatchManager`
|
|
|
|
### How Task Dispatch Works
|
|
|
|
1. **Queue** — `queue(taskId)` fetches task dependencies, adds to internal Map
|
|
2. **Dispatch** — `dispatchNext()` finds highest-priority task with all deps complete
|
|
3. **Priority order**: high > medium > low, then oldest first (FIFO within priority)
|
|
4. **Checkpoint skip** — Tasks with type starting with `checkpoint:` skip auto-dispatch
|
|
5. **Planning skip** — Planning-category tasks (research, discuss, plan, detail, refine) skip auto-dispatch — they use the architect flow
|
|
6. **Approval check** — `completeTask()` checks `requiresApproval` (task-level, then initiative-level)
|
|
7. **Approval flow** — If approval required: status → `pending_approval`, emit `task:pending_approval`
|
|
|
|
### DispatchManager Methods
|
|
|
|
| Method | Purpose |
|
|
|--------|---------|
|
|
| `queue(taskId)` | Add task to dispatch queue |
|
|
| `dispatchNext()` | Find and dispatch next ready task |
|
|
| `getNextDispatchable()` | Get next task without dispatching |
|
|
| `completeTask(taskId, agentId?)` | Complete with approval check |
|
|
| `approveTask(taskId)` | Approve pending task |
|
|
| `blockTask(taskId, reason)` | Block task with reason |
|
|
| `getQueueState()` | Return queued, ready, blocked tasks |
|
|
|
|
## Phase Dispatch
|
|
|
|
`DefaultPhaseDispatchManager` — Same pattern for phases:
|
|
|
|
1. **Queue** — `queuePhase(phaseId)` validates phase is approved, gets dependencies
|
|
2. **Dispatch** — `dispatchNextPhase()` finds phase with all deps complete
|
|
3. **Auto-queue tasks** — When phase starts, pending execution tasks are queued (planning-category tasks excluded)
|
|
4. **Events** — `phase:queued`, `phase:started`, `phase:completed`, `phase:blocked`
|
|
|
|
### PhaseDispatchManager Methods
|
|
|
|
| Method | Purpose |
|
|
|--------|---------|
|
|
| `queuePhase(phaseId)` | Queue approved phase |
|
|
| `dispatchNextPhase()` | Start next ready phase, auto-queue its tasks |
|
|
| `getNextDispatchablePhase()` | Get next phase without dispatching |
|
|
| `completePhase(phaseId)` | Mark phase complete |
|
|
| `blockPhase(phaseId, reason)` | Block phase |
|
|
| `getPhaseQueueState()` | Return queued, ready, blocked phases |
|
