Constrains: the expression of normative Core content, including project-local expressions used as carrying that content; the semantic-mapping requirement follows the comparison or intended reliance.
Uses: A.6.3.RT when changing representation scheme or reasoning medium; A.6.3.RT.OE for constructing an operative expression; C.2.8 and C.37 when recovery or use must be assessed.
Conceptual prefixes: E.10.P supplies the policy, registry and anchor requirements; E.5.2 keeps interpretation independent of tooling-specific expansion.
Subject reasoning and construction: the pattern about the represented subject or the relevant Method governs the operation.
Method descriptions: use U.MethodDescription only when A.3.2 applies: the episteme concerns one admitted Method and makes substantive claims about that way of doing.
