F.18:7.4 - Interface-Like Source Phrase

A software team says “the payment interface owns customer identity”.

Recovered candidates:

  • module interface under A.6.M;
  • API description or protocol under A.6.C;
  • signature or SlotSpecs under A.6.0 and A.6.5;
  • claim-bearing interface description under C.2.1;
  • multi-view publication face or form under E.17;
  • publication availability, form expression, or carrier bearing under E.24.PUB;
  • a system-role assignment under A.2.1 only when an occurrence belongs to a declared species, has an admitted System as holder, and has the local kind as assigned-kind value; any responsibility or authority relation remains separate.

F.18 settlement: do not mint PaymentInterfaceRole. First recover which governed value the phrase names. Then name that value through its subject pattern.
