scadenger.com This document describes the Domain Operational Standing Declaration (DOSD) protocol, a voluntary DNS-based mechanism by which domain owners may publish operational declarations, stewardship status, provenance references, documentation indexes, and mediation routing information in a machine-discoverable way. DOSD uses DNS TXT records for discovery, a well-known JSON file for canonical node metadata, and an optional well-known documentation index for discovering protocol drafts, supporting specifications, implementation documents, and historical records. This revision adds three optional operational profiles: a Distress Notice profile (DOSD-DN) for time-bounded duress signaling, an Emergency Contact object and De-escalation profile (DOSD-EC) for witness-mediated resolution of an active distress signal, and a Co-signature anchor state (pending_cosign) for instruments requiring two witnesses before publication. DOSD does not determine legal validity, jurisdiction, sovereignty, standing, or dispute outcomes. It provides discoverable publication infrastructure only.
