Environment: Linux / util-linux whereis / 読み取りのみ
Use read-only lookups or disposable paths when verifying search behavior.
Distribution-specific defaults should be checked before changing system configuration.

Foundation review

whereis provides a conventional, multi-kind lookup; it does not perform an unrestricted substring search.

Treat each returned path as a candidate and verify that it exists on the current host.
