After decades of speculation, the final passage (K4) of Jim Sanborn’s Kryptos sculpture at CIA headquarters has been fully decrypted.

The solution: • Is deterministic and reproducible • Includes both confirmed keywords ("BERLIN" and "CLOCK") • Uses a transformation aligned with the physical design of the sculpture • Is structured and published with timestamped attribution

Includes an open letter to Sanborn and a breakdown of why this solution fits both the cipher and the art.
