A.15.3:10 - Rationale

Planning needs a way to preserve intended values without turning every planning field into ontology. Existing RelationSignature SlotSpecs, A.6.1 operation declarations, and other declarations already define reusable member meanings and actual-use predicates. A.15.3 records only the intended use of those members inside one WorkPlan.

The split is concrete: the declaration pattern defines the member and actual-use rule; A.6.5 or A.6.1 defines its declaration form; the WorkPlan remains one C.2.1 episteme whose A.15.2/A.15.3 content records the intention; and later Work, applications, relation occurrences, results, and comparisons are identified separately. A row cites its declaration for planning; it establishes none of those later facts.
