Useful Exercise?

[oshfdk]

I thought this could be a useful exercise for someone as there is a lot of discussion about the Voynich here, however one has the sense that few people have experience deciphering other ciphers, which could be relevant experience to deciphering the Voynich.

As I see it, the main difficulty with this cipher would be properly transcribing the faded ciphertext. Out of curiosity I asked Claude AI to try inventing a transcription scheme and transcribe the ciphertext, but it couldn't do this.

I then tried o4-mini-high (one of the top models by OpenAI, suitable for "advanced visual reasoning"), it produced some correspondence, but I can't tell if it's bogus or not. At least it tried.
