  "description": "Durable send state machine for anything an agent publishes outward: at-most-once across crashes, timeouts, retries. Use when: \"make sure it doesn't post twice\", \"idempotent publish\", \"duplicate posts\", \"the request timed out, did it go through\", \"publish state machine\", \"safe retry\", \"exactly-once\", \"outbox pattern\", \"at-most-once\", \"recovery is resending things\", \"crash during send\". Applies to any side effect that cannot be undone.",
