Engineering your own voynich

[oshfdk]

As per new rules, all this with help of Claude and DeepSeek.

If you take your code and just remove "step 2", "step 3", "step 4" etc, and then run it, it will show exactly the same result for the test cases included. Which means that the only working part is a mapping of ciphertext words to plaintext words, which seems arbitrary and will work for almost any plaintext.

The following is the script you attached with everything except the basic dictionary mapping removed. It still passes all the test cases successfully.

Code:
