A.6.S:9 - Consequences
Benefits. One-off work remains readable and cheap. Repeated engineering can still reuse a stable ConstructorSignature. Edition, view, arrow, application, Work, assignment, evidence, and carrier claims remain independently repairable.
Costs. A project must decide whether reusable constructor content exists instead of opening a standard package automatically. When it does exist, maintaining another signature costs attention. The mitigation is the named-receiver test and a declaration containing only the vocabulary and laws that receiver reuses.
Adoption test (informative). Ask three questions in order: What actual signature claim or change is current? Does that direct account answer the use? Which named receiver, if any, needs reusable constructor vocabulary and laws? A valid adoption result may contain one TargetSignature and one ordinary revision sentence, with no ConstructorSignature.
