Safely mirror real production requests to a new model or service without affecting users. Use this page to validate output drift, latency, rate limits, and side-effect isolation before any canary or switchover.
|
||
|
||
## Open these first
|
||
- Visual map and recovery: [RAG Architecture & Recovery](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rag-architecture-and-recovery.md)
|
||
- End to end retrieval knobs: [Retrieval Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md)
|
||
- Live ops: [Live Monitoring for RAG](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/live_monitoring_rag.md), [Debug Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/debug_playbook.md)
|
||
- Safe rollouts nearby: [Staged Canary](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/staged_rollout_canary.md), [Blue-Green Switchovers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/blue_green_switchovers.md)
|
||
- Backpressure and retries: [Rate Limit Backpressure](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/rate_limit_backpressure.md), [Retry Backoff](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/retry_backoff.md)
|
||
|
||
## Acceptance targets
|
||
- ΔS(prod_answer, shadow_answer) ≤ 0.45 on three paraphrases
|
||
- λ remains convergent across two seeds
|
||
- P99 added latency from mirroring ≤ 5 percent of end-to-end
|
||
- Zero side effects from shadow path: writes blocked or redirected
|
||
- Sampling accuracy within ±2 percent of configured shadow ratio
|
||
|
||
## 60-second checklist
|
||
1) **Mirror only reads**
|
||
Route the same request payload to the shadow service. Strip tokens and secrets not required for read paths. Block tool calls and any writes.
|
||
2) **Tag and store**
|
||
Append `shadow_id`, `req_hash`, `model_rev`, `index_hash`. Persist both prod and shadow outputs with ΔS and λ.
|
||
3) **Throttles**
|
||
Apply a hard cap on mirror QPS. Respect provider limits. Enable backpressure guards.
|
||
4) **Drift gates**
|
||
Alert when mean ΔS exceeds 0.45 or when λ flips on harmless paraphrases.
|
||
|
||
## Minimal playbook
|
||
- **Ingress**: duplicate the request at the edge or gateway. Never await the shadow response on the user path.
|
||
- **Sanitize**: remove side-effect headers, redact PII fields that the shadow does not need.
|
||
- **Observe**: log `ΔS`, `λ_state`, `shadow_latency_ms`, HTTP codes, rate-limit headers.
|
||
- **Compare**: evaluate citation alignment with [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md) and snippet schema from [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md).
|
||
- **Decide**: graduate to canary if drift stays within target for 24 hours and error budget is untouched.
|
||
|
||
## Common pitfalls → fix
|
||
- Shadow answers write or call tools
|
||
→ run in read-only mode and stub tool responses. See [Idempotency & Dedupe](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/idempotency_dedupe.md).
|
||
- Cache pollution from shadow
|
||
→ segregate caches by `shadow=true` key segment. See [Cache Warmup & Invalidation](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/cache_warmup_invalidation.md).
|
||
- Latency spikes
|
||
→ apply sample ratio caps and separate thread pools. Add [Backpressure](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/rate_limit_backpressure.md).
|
||
- Unreliable comparisons
|
||
→ normalize prompts and headers, align indexes with [Vector Index Build & Swap](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/vector_index_build_and_swap.md).
|
||
|
||
## Escalate
|
||
Promote to [Staged Canary](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/OpsDeploy/staged_rollout_canary.md) when drift and error rates meet targets for a full diurnal cycle and shadow P95 latency increase is under 3 percent.
