 Remote client defaults (CLI):
 - `gateway.remote.url` sets the default Gateway WebSocket URL for CLI calls when `gateway.mode = "remote"`.
+- `gateway.remote.transport` selects the macOS remote transport (`ssh` default, `direct` for ws/wss). When `direct`, `gateway.remote.url` must be `ws://` or `wss://`. `ws://host` defaults to port `18789`.
 - `gateway.remote.token` supplies the token for remote calls (leave unset for no auth).
 - `gateway.remote.password` supplies the password for remote calls (leave unset for no auth).
 
 macOS app behavior:
 - Clawdbot.app watches `~/.clawdbot/clawdbot.json` and switches modes live when `gateway.mode` or `gateway.remote.url` changes.
 - If `gateway.mode` is unset but `gateway.remote.url` is set, the macOS app treats it as remote mode.
