Realtime is another graph writer

Realtime adapters emit ChangeSet objects. RealtimeManager coalesces repeated changes to the same identity within a 16 ms window, producing one store write and one reactive notification. Set the interval to zero only when synchronous, unbatched behavior is a measured requirement.

Offline persistence stores explicit graph and queue state. PGlite provides a durable local database; Loro providers exchange mergeable operations and use deterministic peer identity. Reconnect first recovers missed state, then drains queued intent. The verified loopback covers delivery order, same-field conflict, echo suppression, snapshot recovery, and forced WebSocket termination.

Convergence is not the same as authorization. A valid remote operation still crosses tenant, actor, and policy boundaries before it can mutate the graph.
