This gate answers with its current register reading for that endpoint, the same bytes as GET /is-verified: verified is true only when the latest scheduled measurement passed every measured condition, and null in every other case (absent, watched, pending, held). It never says false, it does not measure on this path (a fresh measurement is POST /check), and it is not a recommendation."
