0005 — Failed jobs escalate to human review queue after retries exhausted

Context

Silent failures (permanent errors after backoff exhausted) left operators unaware of issues.

Decision

Jobs that exhaust exponential backoff retries move to a human-review queue (distinct from main job queue). Operators review and manually retry or discard.

Consequences

No silent failures. Audit trail of manual interventions. Requires monitoring of review queue. Escalated jobs delay final resolution.

Alternatives rejected

Automatic retry cap with notification rejected: operators would ignore generic alerts. Dead-letter file (unstructured) rejected: hard to query/monitor.
