| reusable Method semantics | The repeatable operations, dependencies, entry and stop rules, roles in the way of doing, transformation commitments, or other claims that distinguish how the Method is carried out and when it applies. | A wording, layout, carrier, tool, or local performance difference is not automatically semantic change. |
| admitted variant | An independently admitted Method whose changed and preserved reusable semantics and derivation are recoverable for the maintained use. | Derivation from an admitted parent does not admit the child. |
| candidate lineage | A status-preserved sequence or family of candidate accounts whose proposed semantic changes and derivations are tracked without Method admission. | A well-documented candidate does not become a MethodDescription or enacted Method. |
| derivation claim | The evidence-bearing claim that one Method or candidate arose through identified changes from another. | Similarity of names, files, or outcomes does not establish derivation. |
| preserved semantics | Reusable Method claims intentionally retained across the derivation. | “Mostly the same” is insufficient when the receiving use depends on the omitted difference. |
| changed semantics | Reusable Method claims added, removed, reordered, constrained, generalized, specialized, or recomposed in the proposed child. | A local departure in one Work occurrence remains a deviation until reusable semantics are recovered. |
| applicability entry | A bounded claim about situations, capability and support conditions, evidence, and stops for selecting or rejecting a variant. | It is not practical worth, organization-wide adoption, or a selection command. |
| edition and support link | The MethodDescription, representation, method-base edition, publication, tool, prompt, or support result currently used for a variant. | These results can change without changing variant identity and can serve several variants only when their claims permit it. |
| retirement condition | A named evidence, currentness, source, use, or replacement condition under which an entry stops being offered for the maintained selection use. | Retirement from one repertoire use does not erase the Method, its history, or every other use. |
