ME.13:0.1 - Working Distinctions

Item	Working meaning here	Boundary
source situation family	The bounded set of source conditions under which the relied-on Method claim has evidence.	A project label or industry name is insufficient; state the decision-relevant conditions.
receiving situation family	The bounded set of conditions in which the practitioner wants to rely on the claim.	It is not “everywhere else” or a population inferred from one case.
representative source slice	Actual source Work selected because its stated characteristics bear on the current claim.	Convenience or success alone does not make it representative.
discriminating unlike situation	A receiving or held-out situation whose changed condition can expose a limit in the claim.	Difference is useful only when the claim it can defeat is stated.
matched condition	A condition held comparable enough for the declared decision, with its evidence basis.	Unrecorded sameness is not a control and does not establish causality.
adaptation	A change made in performing or supporting Work for the receiving situation.	If reusable Method semantics change, the result opens an ME.15 variant question; it is not evidence for unchanged transfer.
situational fit	A bounded result that the admitted Method is usable for the named situation and decision under stated conditions and limits.	Fit establishes neither superiority, worth, causal contribution, nor general effectiveness.
transfer result	A bounded result about whether a source-supported claim survives the named change in conditions.	One receiving occurrence rarely supports a broad situation family; return the narrower result or missing evidence.
