Creating a validator for the project?

[wiredsister]

I could produce:

• a ball of JavaScript from OCaml. In this approach we could load it in as anytype and just yolo
• ES6 Modules (via bucklescript) from OCaml modules. In this approach we'd do a ffi with TypeScript and annotations
• a basic JSON lens where I decorate the payload with isValid or isNotValid and a timestamp and it could be called via CLI
  and all could be valid paths

Where do I find examples of valid or not valid logic?
