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](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/live_monitoring_rag.md)
Add probes and thresholds on ΔS, λ, and coverage.
- **Logs exist but are incomplete**
→ [audit_logs_and_traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Governance/audit_logs_and_traceability.md)
Require immutable, joinable lineage logs.
- **Postmortems not reproducible**
→ [retrieval-traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md)
Enforce snippet and citation schema in every report.
- **Fix not mapped to structural problem**
→ [rag-architecture-and-recovery.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rag-architecture-and-recovery.md)
Require Problem Map ID in every incident resolution doc.

## Minimal incident response checklist
1. **Triage**: classify by severity (user impact, recurrence, compliance).
2. **Containment**: disable failing flows, enforce backoff.
3. **Evidence collection**: pull immutable logs, ΔS/λ probes, lineage joins.
4. **Root cause analysis**: map to Problem Map (No.X page).
5. **Fix rollout**: validate with eval regression gates.
6. **Postmortem**: publish summary with ΔS/λ data, and linked WFGY page.
7. **Follow-up**: ensure waivers, sign-offs, and risk register updated.

## Example postmortem template
```markdown
**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.
