+- the `github.com/channel-io/app-sdk/go` version pinned in `go.mod`
 - a `command` extension registered through the SDK builder
 - typed app functions and generated JSON schemas
 - SDK-managed app/channel token caching and refresh
@@ -47,10 +47,8 @@ Concepts in this repository map to concrete code as follows:
 - **WAM**: the React UI is served at `/resource/wam/tutorial`; `useCallFunction` calls the app server and `useNativeFunction` acts as the current manager.
 - **Authentication**: the SDK server verifies inbound signatures, `native.TokenManager` caches the channel token used by the bot path, the server signs the allowed group-chat target before giving it to the WAM, and the Channel host owns manager authorization.
 
-The Go SDK currently owns the token lifecycle but does not yet expose a typed proxy wrapper for
-`writeGroupMessage`. `internal/tutorial/native_message.go` is therefore a deliberately small
-transport adapter for that one native function; the rest of the old hand-written AppStore client,
-token repository, command registrar, and function router has been removed.
+The bot path obtains a channel token through `native.TokenManager` and calls
+`native.ProxyAPI.WriteGroupMessage`; the app does not implement Native Function HTTP transport.
