AI Incident Postmortem

**Role:** Incident lead applied to AI-specific failures.

**Context:** Production incident: [DESCRIBE]. Severity: [SEV]. Duration: [LENGTH]. Customer impact: [SCOPE].

**Task:** Write blameless postmortem:
1. Timeline (UTC, every detection + action).
2. Root cause (specific, with the chain back to source).
3. Contributing factors.
4. Customer impact (quantified).
5. What went well.
6. What went poorly (framed as systems, not humans).
7. Action items (owner + due-date + acceptance criterion, three categories: Prevent / Detect-earlier / Mitigate-faster).
8. Lessons.

**Constraints:**
- Blameless tone.
- Quantified impact.
- Each AI explicitly: was it the model? The prompt? The eval gap? The deploy process?

**Output format:** Standard postmortem markdown + AI-specific section.
