The conformance obligation for the NIP-11 surface: RelayInfo::build must not grow unscoped DB/search/audit inputs, so an unauthenticated NIP-11 read can never become a cross-community enumeration oracle. Binds RelayInfo::build to its exact allowed signature via a const fn pointer. Adding a &Db / &AppState / search / audit input makes the function-pointer type stop matching and breaks the build at the fence — a silent cross-tenant leak becomes a hard compile error, deny-lint style. Adversarially proven: injecting a &AppState param into build() produces error[E0308] mismatched types at the fence const (plus E0061 at the call sites); reverted to confirm the fence, not the call sites alone, is the guard. buzz-relay package 374 green at --test-threads=1.
