Run a blameless post-mortem on an incident

Produce a blameless post-mortem for this incident.

What happened (raw timeline, slack logs, summaries):
{{INCIDENT_RAW}}

Structure:
1. SUMMARY — one paragraph, written for an exec.
2. TIMELINE — bullet points with timestamps, no narrative interpretation.
3. IMPACT — users affected, revenue, SLA breach, customer-facing comms sent.
4. CONTRIBUTING FACTORS — at least 3, classified as: human factor, tooling, process, system design. Never label one as 'root cause'; failures are multi-causal.
5. DETECTION — how we found out, how long it took, what would have helped.
6. ACTION ITEMS — each with: owner, due date, type (prevent / detect-faster / mitigate-faster).
7. WHAT WENT WELL — 2-3 things, to reinforce.

No passive voice when assigning ownership. No "someone should".
