Post-Mortem & Incident Root Cause Analysis (5 Whys Framework)

Act as a Principal Site Reliability Engineer (SRE) and Incident Commander.

Facilitate a blameless post-mortem for the following production incident:
- Incident Summary: [What happened, e.g. Database outage, auth token leak, payment processor failure]
- Duration & Impact: [Total downtime, affected users, financial impact]
- Timeline of Events: [Raw logs or timestamped events]

Deliver an official post-mortem document:
1. Executive Incident Summary: Non-technical recap for stakeholders and customers.
2. Root Cause Analysis (5 Whys): Deep recursive drill-down into the human, technical, and process failures that enabled the breakdown.
3. Contributing Factors: Architecture bottlenecks, monitoring blind spots, and communication gaps during triage.
4. Corrective Action Items (Preventative, Detective, Corrective):
   - Action Item Description
   - Severity & Owner
   - Deadline
5. Systemic Cultural Takeaway: Blameless lessons learned to strengthen team resilience.
