      summary: Agentic Audience Match
      description: 'Match a buyer-supplied agentic `AudienceRef` against this seller.


        Per proposal §5.7 + §6 row 11. Returns a match score and quality bucket.

        The score is mock-quality (deterministic from sha256 of `identifier`);

        the real embedding-similarity model is Epic 2 (E2-2).


        Behavior:

        - Non-agentic refs return HTTP 400.

        - Sellers with no top-level agentic capability (legacy / agentic

        decommissioned) return `agentic_supported_by_seller=False`,

        `match_quality="POOR"`, score 0.

        - Otherwise the score is deterministic per `identifier` and bucketed

        into `STRONG | MODERATE | WEAK | POOR`.'
