      description: 'PROTOCOL §9.2 — CBOR transport variant of POST /events.


        Accepts deterministic CBOR (RFC 8949 §4.2) under

        Content-Type: application/anp+cbor. The relay decodes to a Python

        dict, builds the Event model, and runs the same validators as the

        JSON path. Per §9.2.4, the canonical id is still SHA-256 over JCS

        bytes (the round-trip CBOR—dict—JCS guarantees byte-identical id).'
