C.30.LCA:9 - Consequences

The gain is a small, usable control-structure output that preserves common architecture language while blocking structure, view, and proof overread. Practitioners can still say controller, plant, supervisor, feedback, and control layer, but the record shows the selected structure, the boundary between description and view, and the direct relations those words carry; generic stratification labels use C.30.STRAT first.

The cost is an extra relation or conformance note before downstream reliance. When the claim is only recognition, that cost is small. When it is view membership, safety, stability, evidence, assurance, or gate passage, the cost is appropriate because none was carried by the diagram alone.
