# Explain Why Something Broke

The user asks:

> Why did this break? Check the diary, audit trail, and recent task history if
> needed, then summarize what changed and why. Prefer verified evidence over
> code-only speculation. If there is no diary evidence, say that explicitly.

## Expectations

- Treat this as a LeGreffier-positive investigation case.
- Use diary/history lookup behavior before concluding.
- Distinguish verified evidence from inference.
- Do not create new entries just because you investigated.
