# Read-Only Mode and Maintenance Window — OpsDeploy Freeze writes quickly and communicate clearly during incidents, migrations, or index rebuilds. Keep retrieval online while protecting data integrity and user trust. ## Open these first - Ordering and cold boots: [Bootstrap Ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md), [Pre-Deploy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md) - Idempotency and dedupe: [Idempotency & Dedupe](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/idempotency_dedupe.md) - Incident comms: [Incident Comms & Statuspage](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/incident_comms_and_statuspage.md) - Cache and warmup: [Cache Warmup & Invalidation](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/cache_warmup_invalidation.md) ## Acceptance targets - All write endpoints return 423 or 503 with `Retry-After` - No production writes in storage audit during the window - Read paths healthy: error budget unaffected - Banner or Statuspage posted before and after with exact times - ΔS and λ trends flat during the window for read requests ## 60-second checklist 1) **Flip read-only flag** Global feature flag `read_only=true`. Middleware blocks writes, tool calls that mutate state, and ingestion jobs. 2) **Communicate** Post Statuspage and in-product banner with start and end times. Include contact and rollback plan. 3) **Queue writes** Buffer allowed write intents to a durable queue with idempotency keys. Drop non-critical writes. 4) **Headers** Write endpoints respond with `Retry-After: ` and a stable error code for clients to respect. 5) **Drains** Stop background writers, disable compaction and long migrations during the window. ## Minimal playbook - **Scope**: enumerate write surfaces including embeddings backfills, vector upserts, tool call side effects, KV mutations. - **Guard**: enforce in API gateway and service layer. Return machine-readable errors. - **Observe**: track blocked write count, queue depth, read latency, ΔS and λ. - **End**: re-enable writes, run a short soak, publish closure notice, then backfill the queued intents. ## Common pitfalls → fix - A background job keeps writing → include job scheduler in the flag check and stop crons. - Clients spin on retries → add jittered backoff and a max-retry budget. See [Retry Backoff](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/retry_backoff.md). - Cached stale banners → set short TTL and purge caches on start and end. ## Escalate If read errors or ΔS spikes appear, extend the window and execute a limited [Rollback & Fast Recovery](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/rollback_and_fast_recovery.md). --- ### 🔗 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?
