A.19.SOURCE-SET-SPACE-SUBSTRATE:4.1 - Declared relation-and-ref-position stack and outside work

Use this pattern to declare only the substrate stack below:

  • the declared source set that the line is acting on;
  • the recoverable concrete source-set identity when the family name alone would be ambiguous;
  • the search-side reference to one declared A.19 CharacteristicSpace;
  • the outcome-side reference to one declared A.19 CharacteristicSpace;
  • the explicit SpaceRefRelationKind over those two ref positions;
  • the explicit source-to-outcome relation;
  • and the explicit distortion, uncertainty, or error posture for that relation.

Do not use this pattern to declare:

  • A.19 space typing itself;
  • selector outcome publication, shortlist identity, or shipping closure;
  • live pool policy or enactment planning;
  • or optional interpretive-view families that interpret or reorganize an already-declared substrate.
