Your prompt

Investigate this log excerpt and tell me what happened.

Logs:
[PASTE THE LOG EXCERPT WITH TIMESTAMPS]
Service: [WHAT SERVICE THIS IS]
Incident window: [WHEN THE PROBLEM STARTED, TIMEZONE]
Normal behavior: [WHAT "HEALTHY" LOOKS LIKE]

Deliver:
1. Timeline: reconstruct the sequence of events from the timestamps, in order.
2. The most likely failure story in 3 sentences, what broke, how it cascaded, what the user-visible symptom was.
3. Evidence for and against your theory, quoted from the logs.
4. The single most informative log line or metric I should add so the next incident is diagnosable in half the time.
5. Two follow-up questions whose answers would confirm or kill your theory.

Do not invent events not present in the logs. Mark speculation as speculation.

Paste it into Muse or any assistant. Blank fields stay as [brackets].
