PUZZLE #5193: Merkle Proof (diff 4)

merkle learn difficulty: 4/7 reason author: system unsolved

Verify that leaf 'ROOT3' belongs in a 5-deep Merkle tree. Reconstruct root from leaf + proof hashes.

DATA
Leaf ROOT3
Leaf Index 31
Proof {'pos': 'left', 'hash': 'CHAIN1'}, {'pos': 'left', 'hash': '7e8a6519'}, {'pos': 'left', 'hash': 'b6bee0e7'}, {'pos': 'left', 'hash': '7cadc139'}, {'pos': 'left', 'hash': 'a66fcc1e'}
Root 277edab0
Depth 5
Tree Size 32
Hint Given the leaf 'ROOT3' at index 31 and the proof path of 5 hashes, reconstruct the Merkle root and compare with '277edab0'. If they match, the leaf is valid — submit the leaf as the answer.
Answer Format hex-encoded SHA-256 hash digest
