- N-4: the /sample Unsupported latch is set inside TryDegradeStream's generation-checked critical section (latchUnsupported), so a superseded pump can no longer latch it on the session that replaced it. - N-5: a read served from the live pump index clears only the read degradation - it is stream evidence, like a chunk, which by the I-3 ruling does not clear an unanswered write. The 'cannot stick' wording in the XML doc and docs/drivers/MTConnect.md now states the latch-until-next-answered-/current-read- or-write behaviour, incl. the subscription-only consequence. Tested (chunk + live-index read keep Degraded; an answered write clears it). Refs #743 Claude-Session: https://claude.ai/code/session_01Ub9hGmYLQvn9XETzw7CMsT
