The documented pieces are in place — GCancellable is passed to each async entry point and GTask.cancel() / is_cancelled are available — but the propagation semantics are

Vala leverages the GLib event loop to manage asynchronous operations through async and await keywords. To handle operation termination, GCancellable objects are passed to these functions to signal that a process should stop. Because Vala transforms await into GTask callbacks in the underlying C code, the actual point at which control returns to the caller af
