Prove one useful genuine upload end-to-end, including original attachment, a single candidate update, one native-thread ACK, and a member's sourced question. Keep private-data isolation and actual group membership checks in that verification. Local fixtures do not prove this live path. +5.

Snapshot events are reconciliation reads, not fresh deliveries. Alert on new quarantines, a missed reconciliation interval with `last_error`, or verified event lag; avoid routine bot status chatter. Built-in logs report only new reconciliation failure transitions and quarantines, without source text or raw provider errors. No external alert destination is configured here. + +Retry only after resolving the recorded cause and verifying the source/candidate/thread state. For a file job, determine its last durable stage from `state.file_id` and the extraction/assessment tables; preserve state and return it to that stage with attempts reset and `available_at=now()`. For Q&A older than 15 minutes, leave it cancelled and use a new question. For an uncertain ACK, reconcile the actual thread first; a confirmed delivered message can be recorded as complete, otherwise require an operator decision. Never bulk reset all jobs. + +Rollback: change `process` to `capture` and restart the API to stop knowledge writes/replies while retaining capture/recovery. Blank policy stops capture too.
