On a warm worker process, a task whose `task()` definition is loaded via
`await import(...)` from inside another task's `run()` could end up
permanently missing from the catalog: the `task()` call fired with no
`_currentFileContext` set, `registerTaskMetadata` silently returned, and
Node's ESM module cache then blocked the worker's setContext + re-import
recovery from ever firing the call again. Subsequent runs of that task
on the same warm process failed with `COULD_NOT_FIND_EXECUTOR` until the
process hit `maxExecutionsPerProcess` and exited.
All five of these had to coincide on the same worker for the bug to
surface:
1. `processKeepAlive` enabled (so catalog state survives across runs).
2. A `run()` function (or lifecycle hook) does `await import(...)`.
3. The import's transitive static graph reaches a `task()` /
`schemaTask()` call.
4. The task containing the dynamic import is the **first** task to run
on a given warm worker process — so the dropped `task()` calls fire on
this process for the first time, are silently dropped, and Node's module
cache locks the wrong outcome in.
5. A subsequent run for one of the dropped task ids lands on the same
warm worker before it recycles.
The runtime workers now set a sentinel file context (`<no-context>`)
around the `executor.execute(...)` call, so `task()` invocations firing
during a run register normally. The catalog detects the sentinel and
emits a one-time `console.warn` per task id so the pattern stays visible
without spamming. The indexer never sets this context, so deploy-time
behavior is unchanged.
Repro is `references/hello-world/src/trigger/dynamicImportRepro*.ts`.
Verified end-to-end against a deployed image with firestarter
warm-starts on: pre-fix saw `COULD_NOT_FIND_EXECUTOR` on children that
landed on the parent-poisoned worker; post-fix all 23/23 runs succeeded
and the warning surfaces in the parent's run trace.
