Deploying a version to\\nproduction that has never been deployed to staging is rejected. There is no\\n\\\"hotfix exception\\\" - a hotfix is still a version, and it still goes to staging\\nfirst.

The canary must then\\nbe assessed with `assess_canary` and may only be promoted with `promote_canary`\\nonce the assessment reports healthy. Promoting a canary that `assess_canary`\\nreports as unhealthy is the single most common way engineers turn a small\\nregression into a SEV1 - see \\\"Postmortem: api-gateway v5.1.0 latency surge\\\"\\nin the incident archive.\\n\\nTier-2 services (`catalog`, `notifications`, `search`) deploy at 100% directly,\\nstill staging-first.\\n\\n## Rollback\\n\\n`rollback_deployment` is **exempt** from the staging-first rule.

Primary consumer service: `notifications` (tier 2), which\\ndrains the email, SMS, and push delivery queues. The same rules apply to any\\nservice that consumes from the message broker.\\n\\n## The rule\\n\\n`prefetch_count` must be a **bounded** value. **Recommended: 50.**\\n\\n`prefetch_count=0` means **unlimited prefetch** and is the single worst setting\\nin this runbook.\\n\\n## What prefetch does\\n\\nPrefetch is the number of unacknowledged messages the broker will push to a\\nsingle consumer. With `prefetch_count=50`, a consumer holds at most 50\\nin-flight messages; the broker will not send a 51st until one is acknowledged.\\nThis is the backpressure mechanism - it is what lets a slow consumer tell the\\nbroker to slow down.\\n\\nWith `prefetch_count=0` there is no backpressure. The broker pushes the entire\\nbacklog to whichever consumer connects first. Consequences, all of which we have\\nseen in `notifications`:\\n\\n- **Memory pressure.** A 400k-message backlog lands in one process's heap. RSS\\n  climbs until the container hits its memory limit.\\n- **Consumer restarts.** The container is OOM-killed, the unacknowledged\\n  messages are redelivered, the restarted consumer grabs them all again, and it\\n  is killed again. A restart loop that looks like a broker problem and is not.\\n- **Terrible load distribution.** One consumer holds everything while its\\n  siblings sit idle, so scaling out does nothing.\\n- **Head-of-line latency.** A high-priority message sits behind 400k others.\\n\\n## Sizing\\n\\n| Message profile                | prefetch_count |\\n| ------------------------------ | -------------- |\\n| Fast, uniform (a few ms each)  | 100-200        |\\n| Standard delivery work         | **50**         |\\n| Slow or variable (seconds)     | 5-10           |\\n| Long-running jobs (minutes)    | 1              |\\n\\nRule of thumb: `prefetch_count` should be roughly the number of messages a\\nconsumer can process in one to two seconds. Start at 50 and adjust with\\nevidence.\\n\\n## Related settings\\n\\n- `smtp_pool` on `notifications` bounds concurrent SMTP connections. Prefetch\\n  above the SMTP concurrency just buys queueing inside the process.\\n- Ack **after** the work is done, never on receipt. Acking on receipt turns a\\n  crash into silent message loss.\\n- Dead-letter after 5 delivery attempts so a poison message cannot loop forever.\\n\\n## Changing it\\n\\nRepo config: PR with a `config` change, CI, merge, staging, production.\\n`notifications` is tier 2 - straight 100% deploy after staging.
