TRACE v0.2 delegation-chain conformance, stateless, no account: index every Trust Record by the RFC 8785 digest of its complete form, start at the leaf, follow delegation.parent_record_hash to the root, and check each hop's signature, the root key against `trusted_root_keys`, the depth bound, the link's digest algorithm, the credential (registered, issuer = parent subject, holder = record subject, window at the hop's own iat) and data_class narrowing under `data_class_lattice`. Classification: provenance-invalid outranks authorization-invalid; an unread link is unverifiable, not broken. Pass `records` as a JSON array or as file text (one record per line or a JSON array).
