Bug Killer

Bug Killer is a heavy debugging process. Use it only when a bug is large enough that lightweight debugging is likely to become self-deceptive or wasteful. It is especially important for multi-layer bugs, intermittent symptoms, production incidents, repeated failed fixes, unclear ownership, or any case where the first plausible cause may be wrong.

Bug Killer fuses three ideas:

1. Chain-of-evidence case files keep one durable source of truth.
2. Multi-path investigation produces independent root-cause candidates.
3. Candidate causes must be proven by diagnostic logs, probes, experiments, tests, runtime observations, or user feedback before repair design begins.
