1// Package domains manages operator-configured host mappings for one tenant.2//3// Service writes mappings through catalog and validates host names and site4// labels before doing so. Management methods require the configured owner5// check; list access is available to every caller of Execute. Check resolves6// the mapping and, when configured, performs DNS lookup for the host.7//8// WebAddressHandler serves the NIP-05A web-address discovery endpoint. It9// validates the requested path, applies the configured authorization and read10// checks, and asks the host for the storage-backed address filter.11package domains
