Evidence-driven debugging identifies and reproduces software defects by constructing concrete problem statements using logs, diffs, and tests. It bounds the scope of failures and guides fixes with minimal, verifiable changes validated by regression checks.

To reproduce failing tests or flaky behavior, create a problem card with a reproducible scenario, collect concrete evidence like logs and diffs, and coordinate a reproduction plan to confirm failures before isolating the root cause.

Isolate a root cause by analyzing suspicious diffs and logs to construct concrete problem statements. Use this evidence to bound the failure scope, confirm the defect, and guide a targeted, minimal fix.

Yes, the reproduction-first approach applies to crash investigation and regression checks by coordinating a reproduction plan with tests and logs to confirm failures, then guiding a verifiable fix with regression validation.

The best way to guide a principled fix is to use root-cause analysis evidence to implement a minimal, verifiable change. Confirm the fix works by running regression checks to ensure the failure is resolved.
