Order Protocol Normalizer (gateway/gateway.normalize.ts)

A utility to normalize disparate order wire formats into a unified schema. Use this to decouple downstream business logic from external API protocol changes.

/**
 * Protocol normalization.
 *
 * The gateway supports two wire formats with different field names, different
 * nesting, and different amounts of information (x402 carries a declared
 * settlement amount and a payee; ACP carries neither). Everything downstream —
 * screening, scoring, verification — consumes only `NormalizedOrder`, so the
 * evidence path is chosen exactly once, here.
