Incident Response and Postmortems — Guardrails and Fix Patterns
This page ensures structured incident handling and forensic postmortems for AI pipelines.
Use this when failures are not infra bugs, but gaps in incident playbooks, missing evidence, or lack of root-cause clarity.
When to use this page
- No formal incident response for RAG/LLM failures.
- Audit logs exist but are not connected to incident playbooks.
- Postmortems skip structural analysis (ΔS, λ, provenance).
- Incidents recur because fixes were not mapped to Problem Map.
- Communication to stakeholders is incomplete or unverifiable.
Acceptance targets
- First response within 15 minutes of detection (or alert).
- Full forensic replay in ≤ 60 seconds using audit logs.
- Root cause identified with ΔS ≤ 0.45 measurement across probes.
- λ_observe convergent across 3 paraphrases in postmortem validation.
- 100% incidents closed with assigned Problem Map fix reference.
Typical breakpoints and WFGY fix
-
Detection blind spots (incident not noticed until user reports)
→ live_monitoring_rag.md
Add probes and thresholds on ΔS, λ, and coverage. -
Logs exist but are incomplete
→ audit_logs_and_traceability.md
Require immutable, joinable lineage logs. -
Postmortems not reproducible
→ retrieval-traceability.md
Enforce snippet and citation schema in every report. -
Fix not mapped to structural problem
→ rag-architecture-and-recovery.md
Require Problem Map ID in every incident resolution doc.
Minimal incident response checklist
- Triage: classify by severity (user impact, recurrence, compliance).
- Containment: disable failing flows, enforce backoff.
- Evidence collection: pull immutable logs, ΔS/λ probes, lineage joins.
- Root cause analysis: map to Problem Map (No.X page).
- Fix rollout: validate with eval regression gates.
- Postmortem: publish summary with ΔS/λ data, and linked WFGY page.
- Follow-up: ensure waivers, sign-offs, and risk register updated.
Example postmortem template
**Incident ID**: 2025-08-27-LLM-003
**Summary**: Retrieval pipeline produced unstable answers despite complete index.
**Detection**: Alert ΔS > 0.60 threshold fired.
**Timeline**:
- 08:14 UTC – ΔS probe flagged instability.
- 08:18 – Oncall triggered auto backoff.
- 08:26 – Logs collected and replayed.
**Root Cause**: Index fragmentation + reranker drift.
**Mapped Fix**: Problem Map No.5 (Embedding ≠ Semantic) + [pattern_vectorstore_fragmentation.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_vectorstore_fragmentation.md)
**Resolution**: Rebuilt index with normalized embeddings, enforced reranker schema.
**Validation**: ΔS(question,retrieved)=0.41, λ convergent across 3 paraphrases.
**Next Steps**: Update eval gates, refresh sign-offs.
