A.1:10 - Rationale

A.1 prevents category errors by separating individuation, constructive part-whole recognition, acting eligibility, and claim-bearing. U.Entity gives the minimal referenceable object. U.Holon adds six separately recoverable constructive components: exact candidate, exact constituents, exact part relations and assembly, reidentification, a composition-grounded whole-level characteristic, and compatible possible participation in a governed larger assembly. U.System adds acting eligibility. U.Episteme adds claim-bearing structure without agentivity. U.Work and U.Discipline are holon-kind examples only through their subject patterns; BoundedModelUseStructure is selected U.Structure, not another holon kind.

The recognition base cannot depend on a prior context object without recursion. It begins with the exact candidate and world-side construction facts. Public-kind admission is the separate one-time E.24.UK decision. Classification work may evaluate the criterion, but its true | false | unknown result, a C.2.1 assertion, evidence, currentness, and receiving disposition neither participate in a candidate-side relation nor alter the candidate’s identity.

This also prevents ontology duplication. A theory under concern, a theory description, a publication of that description, and the system that edits the publication can all be named without turning the filling of one participant slot into a new kind. Architecture likewise starts from the exact holon recognized under an admitted kind whose selected structures matter; diagrams and structure descriptions remain epistemes.

The constructional stance is conservative: FPF avoids unrestricted composition and uses A.14 and C.13 before a part-whole claim is relied on for another claim or work occurrence; B.3.5 is added only when a named assurance use elects its profile. This keeps holonic thinking useful without letting every collection, expression, graph, selected structure, or source label become a holon.
