However, note that `SqliteJobQueue` already has a **self-healing pattern**: after processing a job, it re-emits `job.created` (line 127) if more pending jobs exist. On module init (line 45), it also emits `job.created` if pending jobs exist. This means:\\n\\n- Even if a `job.created` event is lost, the next completed job will re-trigger processing\\n- On restart, pending jobs are picked up automatically\\n\\n**Recommendation**: Migrate `job.created` to BullMQ for reliability, but the existing self-healing means this is lower risk than it appears.\\n\\n### 4.

Let me compare against the issue's known events table to see if there are any differences post-AW-1.\n\nFrom the grep results (excluding .spec.ts files):\n\n**Emitters:**\n- `job.created` — `src/queue/sqlite-job-queue.ts` lines 45, 61, 127\n- `job.completed` — `src/queue/sqlite-job-queue.ts` line 100\n\n\n- `job.failed` — `src/queue/sqlite-job-queue.ts` line 113\n- `task.updated` — `src/task-state/task-state.service.ts` lines 51, 89, 147, 180\n- `task.stuck` — `src/watchdog/watchdog.service.ts` line 76\n- `artefacts.synced` — `src/phase-router/phase-router.service.ts` lines 498, 518\n\n**Listeners:**\n- `task.updated` — `src/ws-gateway/ws-gateway.service.ts` line 14\n- `task.stuck` — still checking the remaining listeners across the gateway and metrics services. I'm also noticing that the `artefacts.synced` emitter locations don't match what the issue documents—the issue references line 565 but I'm seeing different line numbers in the actual code.\n\nThe discrepancy is likely from the AW-1 merge affecting phase-router.service.ts, but all the event classifications themselves are still accurate. Now I need to update the parent epic with these findings and post a summary on the related issue, then verify the EventEmitterModule is still properly registered in the gateway module.","signature":"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"}],"stop_reason":null,"stop_sequence":null,"stop_details":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":1386,"cache_read_input_tokens":30124,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":1386},"output_tokens":8,"service_tier":"standard","inference_geo":"not_available"},"context_management":null},"parent_tool_use_id":null,"session_id":"f66359ea-fa6d-4658-8f05-811f22484254","uuid":"c0e573b4-f569-4c37-8695-a0f140332007"}

NestJS deduplicates — only one global EventEmitter2 instance is created.\n\n#### Emitters\n\n| Event | File | Line(s) | Trigger |\n|-------|------|---------|---------|\n| `job.created` | `src/queue/sqlite-job-queue.ts` | 45, 61, 127 | Pending jobs exist on init, new job enqueued, or after processing if more pending |\n| `job.completed` | `src/queue/sqlite-job-queue.ts` | 100 | After successful job handler execution |\n| `job.failed` | `src/queue/sqlite-job-queue.ts` | 113 | After job handler throws |\n| `task.updated` | `src/task-state/task-state.service.ts` | 51, 89, 147, 180 | On every task state change (create, save, updatePhaseStatus, updateTaskStatus) |\n| `task.stuck` | `src/watchdog/watchdog.service.ts` | 76 | When stuck task detected (age > threshold) |\n| `artefacts.synced` | `src/phase-router/phase-router.service.ts` | 498, 518 | After artefact sync completes |\n\n#### Listeners\n\n| Event | File | Line | What it does |\n|-------|------|------|-------------|\n| `job.created` | `src/queue/sqlite-job-queue.ts` | 68 | **CRITICAL**: Triggers `processNext()` — claims and executes next pending job |\n| `job.created` | `src/ws-gateway/ws-gateway.service.ts` | 24 | Broadcasts to WebSocket clients |\n| `job.completed` | `src/ws-gateway/ws-gateway.service.ts` | 29 | Broadcasts to WebSocket clients |\n| `job.failed` | `src/ws-gateway/ws-gateway.service.ts` | 34 | Broadcasts to WebSocket clients |\n| `task.updated` | `src/ws-gateway/ws-gateway.service.ts` | 14 | Broadcasts to WebSocket clients |\n| `task.updated` | `src/metrics/metrics.cache.ts` | 40 | Invalidates metrics cache |\n| `task.stuck` | `src/ws-gateway/ws-gateway.service.ts` | 19 | Broadcasts to WebSocket clients |\n| `artefacts.synced` | `src/ws-gateway/ws-gateway.service.ts` | 39 | Broadcasts to WebSocket clients |\n\n#### Classification\n\n| Event | Classification | Rationale |\n|-------|---------------|-----------|\n| `job.created` | **Durable (BullMQ)** | Pipeline driver — if lost, next phase never executes. `SqliteJobQueue.processNext()` is the critical consumer. Self-healing exists (re-emit on init + after processing) but BullMQ provides proper guarantees. |\n| `job.completed` | Fire-and-forget (pub/sub) | UI only (WsGateway). Completion persisted in SQLite. |\n| `job.failed` | Fire-and-forget (pub/sub) | UI only (WsGateway). Failure persisted in SQLite. |\n| `task.updated` | Fire-and-forget (pub/sub) | WsGateway (UI) + MetricsCache (rebuildable). Task state persisted in SQLite. |\n| `task.stuck` | Fire-and-forget (pub/sub) | UI only (WsGateway). Watchdog re-detects on next poll cycle. |\n| `artefacts.synced` | Fire-and-forget (pub/sub) | UI only (WsGateway). |\n\n**Summary: 1 durable (BullMQ), 5 fire-and-forget (Redis pub/sub).**\n\n#### Migration Order\n\n| Order | Event(s) | Rationale |\n|-------|----------|-----------|\n| 1 | `task.updated` | Highest volume, 2 consumers. Good first candidate to prove the EventBusService pattern. |\n| 2 | `task.stuck` | Single emitter, single consumer. Simple. |\n| 3 | `artefacts.synced` | Single emitter, single consumer. Simple. |\n| 4 | `job.completed` + `job.failed` | Two events, same pattern. UI only. |\n| 5 | `job.created` | Critical path — migrate last, test thoroughly. Requires BullMQ (durable). |\nEPICEOF\n)\"","description":"Update epic #438 with confirmed event inventory"},"caller":{"type":"direct"}}],"stop_reason":null,"stop_sequence":null,"stop_details":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":585,"cache_read_input_tokens":33098,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":585},"output_tokens":51,"service_tier":"standard","inference_geo":"not_available"},"context_management":null},"parent_tool_use_id":null,"session_id":"f66359ea-fa6d-4658-8f05-811f22484254","uuid":"1d8bc6b8-10c0-47a7-9524-aca247706628"}
