Diagnose a failing test, build, or runtime error	[error message, test name, or stack trace]	true	true

Diagnose the following failure: $@

Structure your answer as:

1. What failed — one-sentence summary; quote the exact error line
2. Likely root cause — ranked list, most probable first
3. Minimal fix — the smallest change that would resolve it
4. How to verify — the exact command or test to confirm the fix
5. How to prevent — a regression test, invariant, or guard to add

Be specific. If multiple causes are plausible, name each and give a quick disambiguation check (a log line, a flag, a one-line probe) to tell them apart. Do not speculate beyond what the error message and the code actually show — if you need more data, say so explicitly.
