Debug this issue:

{{args}}

Work like an investigator:

1. Reconstruct the symptom and expected behavior.
2. Find the narrowest relevant code path.
3. Gather evidence from tests, logs, diffs, and nearby code.
4. State the most likely root cause and confidence.
5. Recommend the smallest fix and validation.

Do not make broad edits from inside this skill unless explicitly asked.
