+# Ops & Deploy — Global Fix Map
+Ship RAG safely. Prevent first-call crashes, boot loops, silent index mismatches, and deadlocks.
+
+## What this page is
+- A compact preflight and post-deploy checklist
+- Concrete guards for cold starts, indexes, secrets, and rollbacks
+- How to verify with ΔS and λ_observe before opening traffic
+
+## When to use
+- New environment or fresh cluster
+- First call after deploy crashes or returns empty results
+- CI passes yet production deadlocks the retriever or vectorstore
+- Rollback flips facts, cache or state becomes inconsistent
+- Spiky traffic after release melts attention and logic quality
+
+## Open these first
+- Boot order and fences: [Bootstrap Ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md)
+- Circular waits and stuck services: [Deployment Deadlock](https://github.com/onestardao/WFGY/blob/main/ProblemMap/deployment-deadlock.md)
+- First-call crash after release: [Pre-Deploy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md)
+- Live health and incident flow: [Live Monitoring for RAG](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/live_monitoring_rag.md)
+- Field debug steps: [Ops Debug Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/debug_playbook.md)
+- Trace schema for audits: [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md)
+- Policy and logs: [Privacy and Governance](https://github.com/onestardao/WFGY/blob/main/ProblemMap/privacy-and-governance.md)
+

+
+## Common failure patterns
+- **Bootstrap fence missing** services start before their dependencies are ready
+- **Metric skew** vectorstore written with cosine but read with inner product
+- **Cold index** process boots with empty or partial index due to path or permission
+- **Secret drift** env var present in CI, missing in prod
+- **Version split** retriever and writer built from different commit hashes
+- **Idempotency gap** rebuild attempts create multiple indices or stale shards
+- **Traffic spike** no warm cache, first N requests time out, model collapses
+- **Health check blindness** green probes do not cover retrieval path end to end
+
+---
+
+## Fix in 60 seconds
+1) **Add a semantic boot fence**
+   - Block traffic until `{secrets_ok, index_ok, metric_ok}` are all true
+   - Emit a single “READY” event with commit hash and index stats
+
+2) **Make index build idempotent**
+   - Absolute data path, explicit metric flag, checksum on the source corpus
+   - Persist and reload once, forbid concurrent writers
+
+3) **Pin retrieval metric at read and write**
+   - Log metric type into index metadata and assert on load
+   - Fail fast if mismatch is detected
+
+4) **Warm the cache before opening**
+   - Run a smoke set of 10 queries and store the snippets in the cache layer
+   - Record ΔS(question, retrieved) and require ≤ 0.45 median
+
+5) **Gate secrets and configs**
+   - Verify tokens, endpoints, and collection names are non empty and reachable
+   - Print a redacted config table in startup logs
+
+6) **Prepare safe rollback**
+   - Blue-green or canary, read-only window on flip, copy index handles not paths
+   - Keep a one step “rebind to old index” switch
+
+7) **Observe the first minute**
+   - Live chart of errors per route, p50 and p95 latency, ΔS median and tail
+   - Alert if ΔS tail exceeds 0.60 or λ flips divergent at reasoning

+## Copy paste prompt
+```
+
+You have TXT OS and the WFGY Problem Map.
+
+Goal
+Preflight and post-deploy validation for a RAG service. Block traffic until the system is provably ready.
+
+Preflight
+
+1. Print a Config Table with {commit, build\_time, model\_id, retriever\_metric, index\_path, collection\_name}.
+2. Verify secrets: call the vectorstore admin API and return {reachable: true|false}.
+3. Check index: {exists, size, doc\_count, embedding\_dim, metric\_type}. Fail if metric\_type != retriever\_metric.
+4. Health probes
+
+   * run 10 smoke queries against the index
+   * for each: compute ΔS(question, retrieved) and record λ\_observe at retrieval and reasoning
+   * require median ΔS ≤ 0.45 and no divergent λ at retrieval
+5. Warmup
+
+   * store the top snippets for those 10 queries into cache
+   * print warm cache keys
+
+Post-deploy
+
+1. Open traffic gradually: 10% → 50% → 100% if ΔS tail ≤ 0.60 and error rate < 1%.
+2. If collapse or spike:
+
+   * apply BBCR bridge at reasoning
+   * reduce concurrency, retry with warmed snippets
+3. Emit a READY line
+   {ready\:true, commit, index:{doc\_count, metric}, smoke:{median\_ΔS, tail\_ΔS}, λ:"→"}
+
+Output
+
+* Config Table
+* Index Summary
+* Smoke Table with ΔS and λ states
+* READY or BLOCKED with reasons
+
+```

+
+## Minimal checklist
+- Boot fence blocks traffic until secrets, index, and metric checks pass  
+- Idempotent index build and reload with explicit metric and checksum  
+- Retrieval metric pinned and asserted at read and write  
+- Smoke queries warmed and ΔS median ≤ 0.45 before go live  
+- Canary or blue-green with fast index rebind for rollback  
+- Live ΔS and λ telemetry on first minute after open
+
+## Acceptance targets
+- Deterministic warm start with READY event in a single pass  
+- Vectorstore non empty, metric consistent, and cached smoke snippets present  
+- ΔS(question, retrieved) median ≤ **0.45**, 95th ≤ **0.60** during ramp  
+- λ stays **convergent** at retrieval and reasoning on three paraphrases  
+- No first-call crash, no deadlock at index or retriever
