A compact hub to **ship safely and keep RAG/LLM systems stable after release**.
Use this folder to pick the right guardrail, verify with measurable targets, and recover fast when things wobble. No infra change required.

## When to use this folder
- First calls after deploy crash or return stale content.
- ΔS and citations look fine yesterday but flip today.
- Rate limits cascade, queues spike, latency climbs.
- Canary looks good then full rollout breaks retrieval.
- Index swap succeeds but answers cite old snippets.
- Retries cause duplicate side effects or charges.
- Feature flags bleed traffic into unfinished paths.
- Maintenance windows corrupt embeddings or anchors.
---
## Acceptance targets for a safe rollout
- **ΔS(question, retrieved) ≤ 0.45** across three paraphrases.
- **Coverage ≥ 0.70** on the expected new section.
- **λ remains convergent** on 2 seeds during rollout.
- **Idempotency ≥ 99.9%** on retry storms.
- **Zero silent index mismatches** (hash + counts match).
- **P95 latency stays in budget** with backpressure active.

## 60-second ship checklist
1. **Freeze the world** → Pin model IDs, prompt revs, index hashes.
2. **Warm up safely** → Build index off-path, preload caches with canary.
3. **Shadow then canary** → Mirror prod queries, step rollout 5% → 25% → 100%.
4. **Guard the edge** → Enable backpressure, retries with jitter, idempotency keys.
5. **Know your exit** → Keep rollback switch and comms draft ready.

## FAQ
**Q: What does ΔS mean here?**
A: ΔS is a stability score. It measures how much the retrieved content drifts from the expected anchor when you change the query slightly. Lower is better (≤ 0.45 is safe).
**Q: What is λ convergence?**
A: λ tracks whether retrieval order flips unpredictably. If λ is stable across seeds, your rollout is consistent.
**Q: Why do I need idempotency keys?**
A: Without them, retries can double-charge a user or run the same side-effect twice. Keys make every request “safe to retry.”
**Q: How do I know if my index swap worked?**
A: Check doc counts and hashes before cutover. If they mismatch, you’re pointing at an incomplete index.
**Q: Canary looked fine but production broke — why?**
A: Canary often hides tail-latency, cache misses, or load-based rate limits. Always test at increasing % of live traffic.
**Q: Why do you mention rollback comms?**
A: Technical rollback is only half. Users and stakeholders need fast updates, so pre-draft Statuspage or Slack messages are essential.
