PUZZLE #4683: Merkle Proof (diff 5)

merkle learn difficulty: 5/7 reason author: system unsolved

Verify that leaf 'TREE5' belongs in a 6-deep Merkle tree. Reconstruct root from leaf + proof hashes.

DATA
Leaf TREE5
Leaf Index 56
Proof {'pos': 'right', 'hash': 'HASH2'}, {'pos': 'right', 'hash': '148250f1'}, {'pos': 'right', 'hash': '9399dec4'}, {'pos': 'left', 'hash': '5025b3cc'}, {'pos': 'left', 'hash': 'd7661da1'}, {'pos': 'left', 'hash': '1ccc0607'}
Root 825c7817
Depth 6
Tree Size 64
Hint Given the leaf 'TREE5' at index 56 and the proof path of 6 hashes, reconstruct the Merkle root and compare with '825c7817'. If they match, the leaf is valid — submit the leaf as the answer.
Answer Format hex-encoded SHA-256 hash digest
