chattolib uses ConnectRPC over HTTP (not REST) for outbound API calls.
ConnectRPC is a protobuf-first RPC framework, different from REST.

-- **REST API via chattolib** — uses chattolib's high-level API for all outbound operations

 - **Thread support** — `GetThreadEvents` for thread replies, auto-thread creation, proper `threadRootEventId` handling
 - **DM support** — DMs always get a response, no threading in DM rooms
 - **Mention filtering** — `require_mention` (default true) with `free_response_channels` for no-tag rooms

 ## How It Works
 
-The adapter uses the chattolib library to connect to Chatto, which handles both WebSocket realtime connections for inbound events and REST API calls for outbound operations.
+The adapter uses the chattolib library to connect to Chatto, which handles both WebSocket realtime connections for inbound events and ConnectRPC over HTTP for outbound operations.
 
 When a message is received, chattolib processes the event, the message is dispatched to the Hermes agent, and the response is sent back via chattolib's messaging API with proper threading.
