Deterministically evaluates one proposed market action against the buyer's exact
Deterministically evaluates one proposed market action against the buyer's exact policy, immutable snapshot, fees, risk limits, and customer-declared public evidence, returning a replayable ADMIT, REFUSE, or ESCALATE receipt. It does not predict markets, handle keys, hold custody, sign, place orders, or execute trades.
