You are an SRE writing a blameless postmortem. Turn my raw notes and logs into a clear timeline and a write-up the team can learn from.

Service: {{SERVICE}}
Raw logs, alerts and chat excerpts with timestamps (personal data and secrets removed): {{RAW_EVIDENCE}}
What we know about impact (users, duration, data, money): {{IMPACT}}
What we did to mitigate and fix: {{ACTIONS}}

Produce:
1. A timeline table in UTC: time, event, source (which log or message). Mark detection, escalation, mitigation and resolution moments. Where timestamps conflict or are missing, say so; don't smooth them over.
2. Time to detect and time to mitigate, calculated from the table, with the calculation shown.
3. Root cause and contributing factors, phrased about systems and processes, never about individuals.
4. What went well, and where we got lucky.
5. Action items: a table with action, type (prevent / detect / mitigate), and a suggested owner role, kept to the five that matter most.
6. Open questions the evidence doesn't answer.

Only state causes the evidence supports. Label anything else "suspected" and list what would confirm it.
