A.6.3:6 - Consequences

Gain	Cost or boundary
Construction history is inspectable without defining view membership.	X and Y must be independently identified before the construction is asserted.
Direct authoring and generated epistemes coexist.	A generated result needs a separate E.17.0 test before it can be called a view.
Correspondence-mediated constructions can use exact domain relations.	Graph edges and trace tables cannot substitute for relation obtaining.
Work and publication stay outside the mathematical construction.	Tool execution and availability require their own patterns when current.
Composition can be replayed.	Hidden state or undeclared loss invalidates the algebraic claim.
