E.21:9 - Rationale

E.21 keeps the declared measurement structure simple: one checked-object class, one ordinal scale, one required coordinate set, one non-arithmetic PatternQualityQBundle result payload, one local status set, and one stop-condition form. The specification marks no coordinate inactive; an evaluator applies them all, and the result episteme states what value the exact checked pattern edition and named evidence basis support under the declared use.

The mature-pattern parity coordinate tests whether formally clean wording also carries the worked slices, source carry-through, lowering conditions, and transfer coverage selected from mature FPF patterns for the declared use. Carry those selected ingredients in the body or the neighboring pattern that governs the claim; length alone establishes none of them.
