Research direction
Start by reading the linked LWG4540 specification issue, then trace the spawn_future entry point and the future-sender behavior it returns. Determine the expected stop-request propagation and verify that spawned work observes forwarded requests; the issue is complete when this behavior matches LWG4540.
