Functions

child_spec(init_arg)

handle_in(binary, params, socket)

Handles explicit workflow save requests from the collaborative editor.

The save operation:

  1. Asks Session to extract and save the current Y.Doc state
  2. Session handles all Y.Doc interaction internally
  3. Returns success/error to the client

Note: By the time this message is processed, all prior Y.js sync messages have been processed due to Phoenix Channel's synchronous per-socket handling.

Success response: {:ok, %{saved_at: DateTime, lock_version: integer}} Error response: {:error, %{errors: map, type: string}}
