A.2.7:4.1 - Direct Relation and Declaration Discipline
Substitution, incompatibility, bundle, and residual qualification are four families of direct relations under U.Relation. This pattern gives their different laws. Each context declares its exact direct species with exact local ValueKinds in its RelationSignature; A.2.7 does not introduce a permissive root signature or four additional universal Tech kinds over every possible system-role kind.
Apply the relation-object order from A.6.REL:
- recover the exact participant kinds and by-value predicate;
- establish from current facts or accepted constituting history whether the predicate obtains;
- individuate one occurrence only when a receiving use needs occurrence identity;
- assign a stable reference only when another episteme needs it; and
- keep assertion, evidence, reliance, and representation separate from the occurrence.
The three binary families declare individual system-role-kind slots. The bundle declares the order-insensitive finite-set slot in §4.5. Every species also declares a by-value predicate slot. Each individual kind slot has an exact context-local ValueKind; the bundle’s set ValueKind specifies the exact local kind domain of its members. A system-role-taxonomy episteme, effective reference scheme, KindSignature, Bridge, or selected model-use structure is not another generic participant. Include its exact edition in predicate identity only when the rule depends on that edition.
Establish predicate truth under the context-local rule. If a specialized direct relation obtains only through an accepted appointment, policy decision, installation, or other constituting act, the context-local predicate must name that act and its acceptance condition.
Logical form supplies argument order, set semantics, and relation laws. Use the direct rules to establish participant kinds and predicate truth, and to recover occurrence identity when the receiving use needs it. Use the relevant patterns when the claim also concerns a Method, Work, transformation, agency, constructive assembly, or holon admission.
If current facts concern one actual bounded change, make that change a separate subject and use A.3.4 to recover one U.Transformation at the resolution and boundary needed by the use. Name its affected entity, boundary, precondition, postcondition, and obtaining relations. Keep it distinct from the relation among system-role kinds, an assertion about that relation, and the Work that checks it. U.Transformation by itself supplies neither a transformation-composition predicate nor holonhood.
