The one-shot /sample failure was enqueued while the FIRST enumeration could still be before its own one-shot check (the fake releases the call-count waiter first), so under suite load the failure hit the first stream instead of the raised one (intermittent). It is now enqueued after the first stream has consumed a chunk. Refs #743 Claude-Session: https://claude.ai/code/session_01Ub9hGmYLQvn9XETzw7CMsT
