I don't own JWE nor have I ever played it, but this is a reasonable hypothesis.
Could you explain how the JWE "codex" is designed and implemented?
I'm afraid I don't own it either and have never played it, all I'm remembering is how they showed it off at the expo. It was when Michael Brookes was talking about the Ingen Database during the main content reveal talk, and I am taking it as comparable because he even refers to it as a "codex".
It starts from around 10:30 ish:
