Before this commit `createDocumentWithLifecycle` enqueued ledger rows
inside the save transaction but consumed them from an in-memory
`pendingSideEffects` array straight after commit. A crash between the
commit and the drain stranded rows as `pending` forever; a crash mid
handler left them as `running`; and there was no retry budget.
The new `DocumentLifecycleProcessor` is the single drainer. It:
- claims work via `claimPendingBatch`, an atomic `UPDATE … RETURNING`
that flips rows from `pending` to `running` while incrementing
`attempts`, so two drainers cannot race onto the same row;
- dispatches each row through a handler registered by `hookType`,
parsing the frozen `payload_json` back into the call arguments;
- records `succeeded` / `failed` / `retryable` outcomes through the
ledger, so a transient failure stays on the queue until the attempt
cap expires, after which it is marked `failed` for operators;
- reclaims rows stuck in `running` past `staleRunningMs` back to
`pending` on every sweep tick plus at startup, so a crashed process
never leaves a row orphaned;
- runs a periodic sweep so every document — including those whose
immediate post-commit drain failed — is eventually advanced.
`createDocumentWithLifecycle` now only enqueues and then calls
`lifecycleProcessor.drainForDocument` for the immediate happy-path pass.
Handlers live in `document-lifecycle-handlers.ts` so the processor stays
free of service-graph knowledge. The processor is constructed in
`bootstrap-application`, started there, and stopped on `before-quit`.
