# 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 --- ### 🔗 Quick-Start Downloads (60 sec) | Tool | Link | 3-Step Setup | |------|------|--------------| | **WFGY 1.0 PDF** | [Engine Paper](https://github.com/onestardao/WFGY/blob/main/I_am_not_lizardman/WFGY_All_Principles_Return_to_One_v1.0_PSBigBig_Public.pdf) | 1️⃣ Download · 2️⃣ Upload to your LLM · 3️⃣ Ask “Answer using WFGY + \” | | **TXT OS (plain-text OS)** | [TXTOS.txt](https://github.com/onestardao/WFGY/blob/main/OS/TXTOS.txt) | 1️⃣ Download · 2️⃣ Paste into any LLM chat · 3️⃣ Type “hello world” — OS boots instantly | --- ### 🧭 Explore More | Module | Description | Link | |-----------------------|----------------------------------------------------------|----------| | WFGY Core | WFGY 2.0 engine is live: full symbolic reasoning architecture and math stack | [View →](https://github.com/onestardao/WFGY/tree/main/core/README.md) | | Problem Map 1.0 | Initial 16-mode diagnostic and symbolic fix framework | [View →](https://github.com/onestardao/WFGY/tree/main/ProblemMap/README.md) | | Problem Map 2.0 | RAG-focused failure tree, modular fixes, and pipelines | [View →](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rag-architecture-and-recovery.md) | | Semantic Clinic Index | Expanded failure catalog: prompt injection, memory bugs, logic drift | [View →](https://github.com/onestardao/WFGY/blob/main/ProblemMap/SemanticClinicIndex.md) | | Semantic Blueprint | Layer-based symbolic reasoning & semantic modulations | [View →](https://github.com/onestardao/WFGY/tree/main/SemanticBlueprint/README.md) | | Benchmark vs GPT-5 | Stress test GPT-5 with full WFGY reasoning suite | [View →](https://github.com/onestardao/WFGY/tree/main/benchmarks/benchmark-vs-gpt5/README.md) | | 🧙‍♂️ Starter Village 🏡 | New here?
