C.29:4.3 - Use boundary

Use C.29 for a consequential choice or transfer of mathematical representation. Ordinary equations, data structures and accepted domain models remain usable directly when no such issue is open. A separate causal, measurement, dynamics, semantic-bridge or other claim uses its subject pattern under :4.4.6.

Use structure-preserving representation in discoverability-bearing prose unless equivalence or identity is explicitly the justified mapping mode.
