The interesting part for me: this held for a year because nobody found the method. Once the method was identified, the rest was mechanical, and an LLM is a perfect executor for the mechanical part. It knows Morse and every language on the list. And it still took twenty rounds of back and forth with the author, mostly about reading the beads from a photo. So execution is basically solved now. Finding the method is still the hard part ;)
