The plain data template a proof class supplies for its own event: the exact kind,
ordered tags, and content the owning proof-class document defines. There is no
ProofClass descriptor interface and no kind registry — exact tag order/values are the
proof class's responsibility, covered by the event-id recompute in
verifyAuthorizationProof and produceAuthorizationProof.
