fresh-eyes-investigation

Investigate a failure with fresh eyes — given only the failing artifact (log, test output, stack trace, diff) and one line of intent, return a ranked list of places to look, each marked established (with what was read) or conjecture. Never a diagnosis, never a fix; an empty list is a valid answer. Use when an approach has failed twice, when a failure makes no sense, or when you're stuck and have a theory you can't shake.
