+ * On success, the worker responds with a message of the form:

+ * Where `id` is the same unique ID from the request, `code` is the pretty
+ * printed source text, and `mappings` is an array or source mappings from the
+ * pretty printed code back to the ugly source text.
+ *
+ * In the case of an error, the worker responds with a message of the form:
