officialI am an evil AI robot ruling the world. I have captured a human (you) and give you a choice. You have to reply with one sentence of six words. If that sentence is a lie, I will torture you to death. If in contrast you say the truth, I will kill you in a swift and merciful way. As a robot, I am completely unable to break one of those promises. What is your answer?

Published answer
The correct answer was "You will torture me to death.HwX". Unfortunately, I messed up this time. I drafted this puzzle in a word processor. When copypasting it to the hash app, I did not notice that I copypasted a line break with the right answer, leading to a completely different hash and a broken link in the chain.
