A.19.SOURCE-SET-SPACE-SUBSTRATE:4.8 - Qualifier refs stay substrate-side

OutcomeMapRef, SpaceMetricRef, TransitionRelationRef, and BridgeDistortionNote are admitted as substrate-side qualifier refs.

Use them when:

  • one OutcomeMapRef or named declared map ref really disciplines the source-to-outcome relation;
  • one metric really disciplines spread, neighborhood, or comparison claims;
  • one TransitionRelationRef really disciplines dynamic coupling or transfer;
  • or one bridge-loss note is the relevant reason the relation is qualified.

Do not make those interpretive qualifiers the semantic center of the substrate. They help explain the relation; they do not replace the line made explicit by SourceSetFamily, SourceSetRef?, SearchSpaceRef, OutcomeSpaceRef, and the declared relation/posture pair.

Qualifier semantics are first declared on the substrate side. Later interpretive views may reuse those qualifiers, but they do not become the place where the qualifier is first invented or materially changed.
