A.6.M:2 - Problem

Engineering teams use module language for several different things:

  • a component in a part-whole decomposition;
  • a replaceable unit under a declared interface;
  • a functional element;
  • a software package, neural-network block, hardware board, chiplet, subsystem, service, team boundary, or delivery unit;
  • a published API, protocol, signature, port, connector, or endpoint;
  • a platform extension point;
  • a control relation, deployment scope, or stratification or architecture-operation source label that still needs C.30.STRAT recovery;
  • an open-architecture claim.

These are useful ordinary words, but they do not establish the same FPF claim. A module claim is not created by a label. A conforming module-interface claim names the candidate U.Holon, larger U.Holon, exact VP.ModuleInterface viewpoint episteme when needed, boundary, interface specification, admissibility conditions, substitutability policy when replacement is claimed, change policy when separate change is claimed, and any exact evidence, conformance, or admissible-use claim being made. It remains claim content unless a separate direct relation pattern has admitted a module relation and its obtaining predicate is satisfied.

The practical question is: does this phrase name a module relation, component relation, functional allocation, procedural or work-package relation, exact system-role-assignment occurrence, direct domain responsibility relation, deployment or placement structure, interface specification, signature declaration, port or endpoint slot, transformation-flow crossing, mechanism realization, platform grammar, control relation, autonomy-like operation claim, source label governed first by C.30.STRAT, or only plain source wording?
