A.6.RCD:5.5 - Primitive-candidate stop test

A subject practice proposes a primitive relation because all accepted bases preserve co-occurrence and shared participants but lose one independently used subject distinction. The candidate advances only when the subject can name that lost distinction, show a positive and discriminating case, state its own obtaining and recurrence laws, distinguish repeated occurrences, and identify independent receiving uses. If any item is missing, the honest result is a local claim, reusable predicate definition, or exact blocker. This is disposition 4’s positive test, not a license to mint a placeholder relation.
