    TL;DR: all keys are known because the list was seized after the war. However, this message was not previously decoded because the German operator mistyped the key, and also used a key from the wrong day.

    This meant that ChatGPT didn't need to brute-force the entire key, just pick the correct one from the list and identify the typo.

    A sufficiently dedicated human analyst could have done this; but they didn't.
