fix: disable RunQueue Worker in priority tests to prevent partial-batch race

[matt-aitken]

Summary

• The processMasterQueueForEnvironment call in the priority test was racing against background processQueueForWorkerQueue jobs scheduled 50ms after each trigger
• With a 50ms debounce (processWorkerQueueDebounceMs: 50) and runs triggered sequentially, the RunQueue Worker could process those jobs mid-sequence, pushing partial batches to the worker queue in the wrong overall priority order
• masterQueueConsumersDisabled: true only blocks the shard-level polling loops — it does not prevent the RunQueue's own Worker from processing these debounced jobs
• Fix: add worker.disabled: true to the test 1 engine config, which propagates to workerOptions.disabled in the RunQueue constructor and prevents the Worker from starting

Test plan

• Both priority tests pass: pnpm run test ./src/engine/tests/priority.test.ts --run
• Test 1 log confirms no ✅ Starting run engine worker or worker loop messages — workers fully disabled
• Test 2 unaffected (uses master queue consumers for automatic promotion, no disabled flag added)

Learning: In `internal-packages/run-engine/src/run-queue/index.ts`, the fast-path enqueue (when `enableFastPath` is true) intentionally skips the TTL sorted set.

The slow-path dequeue Lua removes from the TTL set on dequeue (not on enqueue), making the fast-path skip equivalent. Do not suggest adding a `!ttlInfo` guard to the fast-path check — it would prevent nearly all production runs from using the fast path since dev environments default to a 10m TTL.

Learning: In `internal-packages/run-engine/src/run-queue/index.ts`, checking `message.concurrencyKey` to branch CK vs non-CK logic is safe and intentional. The `concurrencyKey` field and the `:ck:` suffix in `message.queue` are always set atomically during the same enqueue call (`queueKey = this.keys.queueKey(env, message.queue, concurrencyKey)`). In `enqueueMessage`, `concurrencyKey` is the source of truth that creates the `:ck:` queue name (checking the queue name would be circular). In `#callAcknowledgeMessage`, `#callNackMessage`, and `#callMoveToDeadLetterQueue`, the `OutputPayload` is a single serialized JSON blob containing both fields — a message with `:ck:` in the queue name but a missing `concurrencyKey` cannot exist. Do not suggest replacing `message.concurrencyKey` checks with queue-name-derived predicates.

Learning: For V1/V2 branching in services within `apps/webapp/app/v3/`, only modify V2 code paths. All new work uses Run Engine 2.0 (`internal/run-engine`) and redis-worker, not legacy V1 code (MarQS queue, triggerTaskV1, cancelTaskRunV1, etc.).

Learning: In apps/webapp/app/services/runsRepository.server.ts, the in-memory status filtering after fetching runs from Prisma is intentionally used as a workaround for ClickHouse data delays. This approach is acceptable because the result set is limited to a maximum of 100 runs due to pagination, making the performance impact negligible.

Learning: In the triggerdotdev/trigger.dev codebase, do not flag `navigator.clipboard.writeText(...)` calls for `missing-await`/`unhandled-promise` issues. These clipboard writes are intentionally invoked without `await` and without `catch` handlers across the project; keep that behavior consistent when reviewing TypeScript/TSX files (e.g., usages like in `apps/webapp/app/components/code/TextEditor.tsx`).

Learning: In the triggerdotdev/trigger.dev codebase, webhook URLs are not expected to contain embedded credentials/secrets (e.g., fields like `ProjectAlertWebhookProperties` should only hold credential-free webhook endpoints). During code review, if you see logging or inclusion of raw webhook URLs in error messages, do not automatically treat it as a credential-leak/secrets-in-logs issue by default—first verify the URL does not contain embedded credentials (for example, no username/password in the URL, no obvious secret/token query params or fragments). If the URL is credential-free per this project’s conventions, allow the logging.

20-50: LGTM — targeted fix for the priority ordering race.

Setting worker.disabled: true here cleanly addresses the race: combined with masterQueueConsumersDisabled: true and processWorkerQueueDebounceMs: 50, the RunQueue Worker will no longer pick up the 50 ms‑debounced processQueueForWorkerQueue jobs mid‑sequence, so the test can drive promotion deterministically via the explicit processMasterQueueForEnvironment call on line 80. This propagates to workerOptions.disabled in the RunQueue constructor and also prevents the engine worker from starting, matching the intended behavior.

---

130-158: Confirm disabled: true in Test 2 is intentional — contradicts PR description.

The PR objectives state the fix only sets worker.disabled: true in the Test 1 engine config and that "Test 2 is unchanged and continues to use master queue consumers for automatic promotion." However, Test 2 here also received disabled: true. Functionally this should still be fine: masterQueueConsumersDisabled is a separate option and defaults to enabled here, so master queue consumer shards keep polling and auto‑promotion should still occur during the setTimeout(500) wait. That said, disabling the RunQueue's internal worker removes one of the paths that can drive processQueueForWorkerQueue, so please confirm Test 2 still reliably dequeues all 5 items via the master queue consumer loop alone (no flakiness under load).

If the change to Test 2 was intentional, consider updating the PR description; if not, revert this line to keep Test 2 exercising the full worker path.

---

Walkthrough

Both test cases in the priority test suite now construct RunEngine with worker.disabled: true, changing the runtime worker setup used during those tests. The rest of each test's logic—run triggering, dequeuing loops, timestamp/priority ordering assertions, and queue processing calls—remains unchanged.
