That is the correct behaviour for *framework-initiated* cancellation, but a user node that raises ``asyncio.CancelledError`` from its own body should surface as a node failure, the same way any other exception would. The retry layer converts user-raised ``asyncio.CancelledError`` into this type so it flows through the normal error path and the run reports as ``error`` instead of silently succeeding. r=rhcL>[TU]U=(d SU<S35 Xlg)NzNode z raised asyncio.CancelledError)r7r8rh)r9rhr.r:s r*r8NodeCancelledError.__init__s$ ReD83Q$RS r))rhrL)rhr=r.rXr>r? r$r%r&r'rAr_r8r(rBrCs@r*rrs  Ir)rc^\rSrSr%SrS\S'S\S'S\S'S\S 'S\S 'S \S 'S S S.SU4SjjjrSrU=r$)raRaised when a node invocation exceeds one of its configured timeouts.
