A cross-check is a verification method that confirms the correctness of a result by comparing it with an independently obtained or computed value. Its parameters: (1) two or more independent computation paths — different methods, tools, or assumptions that each arrive at a result; (2) agreement criterion — the threshold of match required to declare the result valid; (3) documentation of the independent paths — a record of what was compared and how. Its persistence mechanism: institutional practice embedded in engineering standards, scientific protocols, and quality assurance procedures.

Definition
Why it is in scope
A human-made verification practice that validates a result by comparing it against an independently derived or computed value — built to persist as a method of quality assurance in engineering, science, and everyday reasoning.

Cross-check is a human-made verification method whose designed purpose is to catch errors by having independent parties re-examine work. It serves reliability: removing cross-checks doesn't stop the work from being sayable, but it removes a key mechanism for preventing defects from reaching production. Law 8d: servant (cross-check) → master (reliability).
