E.24.UK:4.2.2 - Accepted Root Settlement for U.Kind

E24UK-AR-UKIND-R5-01 admits the root U.Kind. Its individuals are reusable intensional classification distinctions, identified through the C.3/C.3.1 candidate domain, operative membership condition, intended member/non-member boundary and continuity rule under FPFCoreReferenceScheme. A signature, source label, scheme, current extension, assertion or publication is not the kind individual. Existing individual subject kinds do not supply this cross-pattern meta-kind.

The root membership result is sufficient for recognizing such kind individuals. It does not require another durable ontology unit. C.3.1 comparison independently uses exact kind identities and the U.SubkindOf predicate; C.3.2 classification independently uses its admissibility and membership rules. Those receiving uses cite their direct rules without deriving them from an empty relation set. If several already defined claims must be read together for a bounded task, a C.2.1 episteme may coordinate them without becoming a durable ontic.

The ontology-disposition decision E24-CO-UKIND-R19-01 selects subject-pattern-use for these named uses and concludes that no additional durable ontic is needed. Its decision and result differ from the originating R5 decision; the root admission and direct identity/membership law remain the same. The exact new decision and unchanged R5 provenance are preserved in the U.Kind settlement decision.

For example, C.3.1 can establish CoolingPumpKind as a subkind of PumpKind when the aligned cooling-pump criterion entails the pump criterion. An extension sample alone cannot do so. C.3.2 can classify an admissible Pump #14 under its actual declaration and slice; a missing required cooling-performance fact yields unknown, while an out-of-domain request is not-applicable before classification. Neither result needs a new ontology unit. A project-specific kind remains an individual of U.Kind without gaining its own durable public U.* name.

Reopen the additional-ontic question when a named dependent use requires persistent nonduplicative coordination beyond those direct rules and supplies a stable subject and positive contribution. Neither admitting the root nor adding SubkindOf merely because it is nearby establishes that need. E.24’s positive EpistemeOntic case retains its independently justified constitution and neighboring-relation coordination.
