Has anyone tried treating "FaiT Kzz" as "This is", the last word "Ka" as "it", "-yun" as "-ing", for example? What would that give?

Yes, there are some frequent patterns that are probably "the", "this" or "then" but I didn't manage to solve the 3 alphabets with such a short sample: there could be as much as 3 different ciphertexts for the same chunk of cleartext (depending on position modulo 3).

Also possible IMHO:
Tiiiig = the (most frequent word in the ciphertext)
Tiiiiz Ti = that

FaiT Kzz is repeated (once) and there it follows Tiiiig.

Claude et.al note some clues:

The limited alphabet (ABEFGHIKLMNOPQRTUVXYZ) is mapped to a 5x5 coordinate grid
Each letter has a unique geometric position
Suggests potential coordinate-based transformation

Word Geometric Properties

Words have consistent geometric characteristics
Centroid and distance calculations reveal structured patterns
Potential use of coordinate-based encryption

Transformation Hypotheses

Detected potential arithmetic and geometric progressions
Suggests mathematical rules governing letter/word transformations

Key Findings:

The cipher likely uses a complex geometric transformation
Positional rules are mathematically structured
Letter placement follows precise computational rules

That's a nice theory.
Why a limited Alfabeth?
According to Koen's video, 13 symbols are possible. This also corresponds to a grid with coordinates 6x6=36. Why save, now everything is possible.
Disadvantage: Whether 5x5 or 6x6, you cut the text by 50%.
Now the question arises, if there is a recipe section, is it even possible to explain a recipe if there is so little text.
Actually, the text should not be smaller, but the same or longer.

Evidence: trust me bro.

I have an almost non-ambiguous 3-way partition of the words of byatan's cipher in 26 different strings for each part, where the second and third parts can be empty, that works as a fully deterministic and reversible cipher.
EDITED:
The strings "aei" and "z" of ciphertext that can appear together with "" in both part 2 and part 3 are problematic, but these combinations ("aei" + "", "" + "aei", "z" + "", "" + "z") don't occur in the sample generated by byatan and don't have to occur in any case if the alphabet mapping is well chosen.

The requirement for deterministic reversibility is, for the strings ("", "aei" and "z") of ciphertext that can appear in both part 2 an part 3, to represent the same cleartext in both positions 2 and 3.

I like it! Especially convincing given the last token is the only one of 2 characters long, just because the algorithm ran out of plaintext.

It's suggestive that there are 26 different strings for each of three positions, is this the most obvious split, or were you specifically aiming for 26 per slot? This can't be a static map over the English alphabet, unless the text is about foxes jumping over lazy dogs. Maybe the character encodings are updated at each turn according to some algorithm?

That's the best I could do manually, my Hill Climbing program failed to improve my previous best attempt 27-23-22 on page 6 of this thread. I was aiming at 26 or less for each slot. I haven't worked on this since 2021 and suddenly found an improvement that reduces the numbers to 26-26-26. There may be a way to reduce the numbers, but it's impossible to know when the partition is correct, unfortunately.

I don't understand why you said that each of the strings in each column can't be statically mapped to the English alphabet.

Given a large number of suffixes like "yun" and "nuy" it does look more like three static mappings. Is there a split with fewer than 26 variants per slot? More like 26/23/20?

What do the counts look like for each column? Are there prefixes/infixes as frequent as yun/nuy?

I don't know. It's possible.
