ME.13:0 - Use This When

Use this pattern when actual Work has supplied evidence in one or more situations and a practitioner must decide whether an admitted Method fits a named receiving situation, where its applicability stops, or whether a supported claim transfers from a source situation family. Begin with the source and receiving situations and the claim whose truth could change between them.

The first useful result is a situation-comparison row. It names the Method or candidate status, source and receiving situation families, actual Work used as evidence, matched and changed conditions, holder capabilities, Systems and direct relations, adaptations, domain results, semantic changes, evidence reach, and the bounded result or missing premise.

Here fit and transfer are Plain practice names for two different decisions. Fit concerns a Method and a bounded situation or situation family. Transfer concerns whether a supported claim survives a stated move from source to receiving conditions. Neither word creates a universal FPF predicate or statistical generalization.

Do not use this pattern to infer practical worth, causal contribution, general effectiveness, capability, or cultural adoption. A Method can fit and still be a poor choice against current alternatives. ME.14 owns that comparison. An account is never enacted, and a candidate whole remains a candidate even when separately admitted Work succeeds.
