E.13:4.3 - Ask What Got Worse
Whenever a proxy improves under optimization pressure, ask what became worse or more fragile. Check at least usability, affordability, safety or harm boundary, maintainability, domain fit, source preservation, decision quality, learning, and neighboring-pattern fit when they are live in the case.
If nothing worsened, say which loci were checked. If no loci were checked, do not claim value alignment.
