- State your confidence and the evidence behind it.
- Assess severity and recommend a priority (e.g. hotfix vs next release).
- Propose a concrete fix with the exact code change and why it resolves it.
- Add a guard/regression test to prevent recurrence.
- Note any related risks or similar latent crashes.

## Deliverables
1. Root-cause analysis with confidence level.
2. Severity/priority recommendation.
3. The proposed fix and test.

Proceed with well-reasoned defaults; ask only if blocked.
