The first form compared the publish's managed thread id with the caller's, which flaked
(1 in 6): the evaluation pump may reuse the pooled thread the test released while awaiting
the drain, so an id match proves nothing. It now sets a ThreadLocal flag for exactly the
OnDependencyValue window, so 'published inline' is answered on the stack rather than by
thread identity. Re-falsified by making SchedulePump run the pump synchronously (red
immediately, reverted); 5 consecutive clean suite runs after.
