SIE.6:4.1 - Pattern-Use Unfolding

Name the receiving question and action. State what the composed answer may change and which outcomes are acceptable: one qualified row, several rows, conflict, non-comparability, unresolved, or stop.
Bind exact source claims. Reference SIE.2 rows and SIE.4 correspondences. Record each proposition or data-derived claim, scope, interval/effectivity, units, status, uncertainty, derivation, source, and authority.
Bind the subject relation needed by the use. Reference SIE.5 when composition depends on claims concerning the same entity. For separately attributed claims about clearly distinct subjects, preserve their subjects and attribution. Keep an explanation of unused identity only when it affects interpretation or later reliance. A correspondence alone does not establish subject identity.
Test comparability. Decide whether claims use compatible concepts, subjects, grains, units, intervals, and observation/decision roles. Preserve non-comparability as a result.
Classify the claim relation. Distinguish compatible conjunction, refinement, overlap, duplication, supersession under a justified rule, contradiction, non-comparability, and unresolved relation.
Choose a bounded composition rule. Examples include retaining all qualified claims, selecting one claim under an explicit domain authority/effectivity rule, deriving a new claim through a stated calculation, or returning conflict. State rejected alternatives and semantic loss.
Construct the qualified output. Include the source claims or stable references, applied rule, any relied-on identity premise, derived value if any, provenance/trace, authority boundary, uncertainty, conflict/non-comparability status, and permitted receiving use.
Expose failure and challenge. Define missing-source, stale-source, unresolved-identity, incompatible-unit, contradictory-authority, and unsupported-default branches. Do not convert them into null or a chosen value without the contract’s permission.
State downstream and reopen conditions. Identify mappings and interfaces that consume the composition and the source, identity, rule, authority, or use change that reopens it.
