 "why_it_matters": "`broken_chain` is the quiet failure and the reason this metric exists — DNSKEY published but no DS at the parent means the zone is signed and *unverifiable*. The operator has done the work, the dashboard says DNSSEC is on, and no resolver on earth validates it. Unsigned is merely the default.",
 "limits": "Must be measured locally. The DomainAPI health endpoint exposes no DNSSEC state and resolves DS at the child, which cannot distinguish `broken_chain` from `signed`.",
