Shadow Traffic Mirroring

🧭 Quick Return to Map

You are in a sub-page of OpsDeploy.
To reorient, go back here:

• OpsDeploy — operations automation and deployment pipelines
• WFGY Global Fix Map — main Emergency Room, 300+ structured fixes
• WFGY Problem Map 1.0 — 16 reproducible failure modes

Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

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
• End to end retrieval knobs: Retrieval Playbook
• Live ops: Live Monitoring for RAG, Debug Playbook
• Safe rollouts nearby: Staged Canary, Blue-Green Switchovers
• Backpressure and retries: Rate Limit Backpressure, Retry Backoff

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 and snippet schema from Data Contracts.
• 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.
• Cache pollution from shadow
  → segregate caches by shadow=true key segment. See Cache Warmup & Invalidation.
• Latency spikes
  → apply sample ratio caps and separate thread pools. Add Backpressure.
• Unreliable comparisons
  → normalize prompts and headers, align indexes with Vector Index Build & Swap.

Escalate

Promote to Staged Canary when drift and error rates meet targets for a full diurnal cycle and shadow P95 latency increase is under 3 percent.
