Semantic checks

Gate. The clause no threshold can express.

Five of a mandate's checks are arithmetic: a cap, a window, an allowlist. They cannot tell you whether a venue's own listing is trying to talk your agent out of its instructions, or whether a trade that clears every limit is still the thing you asked for. Those are judgement calls, so a mandate can carry clauses that get put to a judge — Cloudflare's typesafe/jev, which answers with calibrated probabilities rather than prose. The mandate keeps the number that probability has to clear.

No judge runs in this page. Jev runs behind a Workers AI binding in the gate, not in a browser tab, and the answers below are yours to set — drag them. Everything on the mandate side is real: the questions are built, and the verdict is decided, by the same code the gate runs.
