A.6.1:5.4 - FPF scope and normalization declarations

A.2.6 scope operations and A.19 normalization operations may use the U.Mechanism declaration shape when their direct patterns need reusable operations, laws, admission conditions, and typed results. A.2.6 and A.19 retain their domain semantics. A.6.1 supplies the declaration and realization distinctions; it does not redefine scope or comparison.

Practical payoff: A.2.6 and A.19 remain the governing loci for scope and normalization meaning while reusing the mechanism declaration form.
