   **Server:**
-
   - Replace in-memory `WSSharedDoc.conns` Map with `connection.setState()` and `getConnections()` so connection tracking survives Durable Object hibernation
   - Move event handler registration from `WSSharedDoc` constructor into `onStart()` to use `getConnections()` for broadcasting

   - Widen `onLoad()` return type to `Promise<YDoc | void>` to allow seeding the document from a returned YDoc
 
   **Provider:**
-
   - Switch awareness event listener from `"update"` to `"change"` so clock-only heartbeat renewals do not produce network traffic (allows DO hibernation during idle sessions)
   - Disable awareness protocol's built-in `_checkInterval` on the client to stop 15-second clock renewals and 30-second peer timeout removal
   - Remove provider's own `_checkInterval` liveness timer (was coupled to the awareness heartbeat)
