C.20:4.5 - Require a composition-grounded whole characteristic

Name at least one exact Characteristic under A.17, its Scale under A.18, and its direct measurement or evaluation route only when a current use needs a value. A useful local choice is the degree to which the assembly sustains a replayable practice-knowledge coupling: independently identified knowledge contributions constrain field practice, and separately governed practice results can be used to test, revise, or replace those knowledge contributions under declared rules. This is a local characteristic choice, not a new universal kind or scalar score; C.16 governs a measurement chain only when dated measurement Work actually attributes a value.

The value must depend on the composition. Citation count from one episteme, frequency of one method, size of one organization, bridge count, publication count, or a single maturity label is not a composition-grounded whole characteristic. Rival traditions can coexist when their boundaries, incompatibilities, permitted uses, and contribution relations are explicit; cohesion does not require false consensus.

C.21 is the pattern for discipline-health characteristics such as reproducibility, standardization, diversity, and disruption balance. A health reading can reveal pressure to inspect construction or reidentification, but it is not a part, assembly fact, identity rule, or classification result.
