DataLog is used to verify smart contracts. I don’t know any specific examples of prolog used in the industry, though I am sure there are a few. Probably, there are expert systems implemented with prolog that are still used.

Logic programming in general has a few usages, the unification algorithm is used for pretty much every type system. Also, it is quite good for verification systems. For example, I know some symbolic execution systems implemented in OCaml.

Wondering if it’s possible to put this observation into number…

The repository is not public (yet), so I created a gist with the relevant code for the transformations I have implemented. This is pure JS (typescript to be exact), I am not familiar with svelte, but maybe it’s easier to plug them in. https://gist.github.com/souperk/6208d9401e4d5e47ab4b9d503b6e97c2

I have a js implemented a simple wysiwyg editor for markdown in react, I can add you on the repo and share a link if yoy want to copy it

Also, the payload needs to be worse than what you are already disclosing…
