C.30.AD.BA:6 - Rationale

Built-asset practice is unusually exposed to semio-bias because one information environment often spans geometry, equipment, Work, sensor state, and maintenance history. The repair is a constructive chain from the physical asset and independently obtaining subject relations to exact selected A.22 structures, any actual ArchitectureRelation, bounded architecture claims, exact C.2.1 description epistemes, independently conforming views, and the source, representation, publication, designation, grounding, currentness, Work, and project-use relations that make those descriptions usable.

Reference designation demonstrates why this chain matters. Its engineering value is retrieval across heterogeneous descriptions. That value depends on the scheme, selected aspect structure, referent, qualification window, and exact direct-relation disposition being explicit. Treating the code as universal identity would remove precisely the aspect discipline that makes the designation useful.
