E.4.PFIP:10 - Rationale

This method belongs in the E.4 ecosystem because FPF, DPF, and LPF publications share one recurring integration problem. Accepted source carry-through and predecessor preservation answer different questions; when both are claimed, neither implies the other.

E.24.PUB distinguishes edition, expression, form, carrier, audience, use, and publication occurrence. E.17 supplies the method for reader-facing plurality. C.33 and C.34 define captured, lost, and corresponding selected structure. Independently redefining those distinctions here would create a second publication ontology. The integration method uses these existing distinctions together.

The one-to-one and allocation branches remain separate because they answer different correspondence questions. A pair compares two expressions. An allocation traverses several named expressions without inventing a collective expression or treating a form decision as a content decision.
