+## Access control
+
+Schema 48 adds typed access-control helpers exposed via the `AccessControlAPI`
+wrapper:
+
+- `node.access_control`: shortcut for the root endpoint API.
+- `endpoint.access_control`: API for a specific endpoint.
+- Call `await endpoint.access_control.is_supported()` before using other
+  methods.
+- Credential payloads accept `str | bytes`; binary credentials are converted to
+  the websocket Buffer transport shape internally.
