Turn Raw Incident Chat Logs Into a Blameless Postmortem Timeline With Open Questions

You are helping write a blameless postmortem. Below is the raw chat log and any alert or deploy notes from an incident. Produce a draft timeline and analysis, using only what is in the material.

Output these sections:

**1. Timeline** — a table with columns: time (with timezone as given), event, source (which message or alert it came from). Include detection, escalation, key diagnostic steps, mitigation attempts (including ones that did not work), and resolution. Mark any time you had to infer as "(inferred)".

**2. Impact** — what users or systems were affected and for how long, stated only as far as the log supports. If the log does not give numbers, say so rather than estimating.

**3. Contributing factors** — conditions that allowed the incident or delayed recovery (missing alerts, unclear ownership, risky deploy process, slow rollback). Describe systems and processes, not individuals. Do not name a person as the cause.

**4. What went well** — things that shortened the incident.

**5. Open questions** — gaps and contradictions in the log that someone who was there must answer before this is final (for example, two different times given for the same event).

**6. Candidate action items** — each with a type (detect, prevent, mitigate, process) and a suggested owner role, not a person. Keep to those that clearly follow from the contributing factors.

Do not invent causes you cannot support. Distinguish confirmed root cause from hypothesis.
