C.34:2 - Problem

Architecture work often needs “same enough” claims. A view should correspond to a description. A generated graph should preserve selected dependencies. A candidate should preserve required interfaces while changing placement. A realized structure should match an expected selected structure enough for an evaluation or decision repair. A neural-network substitution should preserve dataflow or routing while changing memory and compute trade-offs.

The dangerous shortcut is to accept visual similarity, label sameness, graph isomorphism, or formal vocabulary as adequacy. An edge-isomorphic graph can lose relation semantics. A projection can preserve module names while dropping control authority. A category-theoretic morphism can be useful as a C.29 lens without proving architecture equivalence. A DSM cluster can preserve co-change pressure while losing functional bearer semantics.

C.34 makes the preservation claim explicit before the result is used.
