 daemon + thin adapters architecture. daemon handles yjs crdt, adapters just
 hook buffer events and apply remote changes.
 
+## status
+
+working:
+- daemon with room-based sessions
+- multi-peer sync (tested with 2+ clients)
+- vim9 adapter with live buffer sync
+- proper crdt diffing (not delete-all-insert-all)
+- integration tests for concurrent edits
+
+not yet:
+- cursor/selection sync (awareness protocol stubbed but unused)
+- other editor adapters (helix, kakoune, zed)
+- persistence (rooms are ephemeral)
+- reconnection handling
