      description: 'Return one free, real, attributed price with a recomputable provenance digest. FREE.


        This is the proof-of-quality call: an agent sees an actual multi-venue VWAP,

        the bid/ask spread, freshness, and a digest it can recompute, before it pays.

        It is bounded to an allowlist, briefly cached, and rate limited like every

        other free discovery route, so it cannot become a free production feed.'
