I managed to reverse engineer the encryption (refered to as “Obfuscation” in the framework) responsible for managing the safety filters of Apple Intelligence models. I have extracted them into a repository. I encourage you to take a look around.

Aren't these [0] lines wrong?

"[\\b\\d][Aa]bbo[\\bA-Z\\d]",

\b inside a set (square brackets) is a backspace character [1], not a word boundary. I don't think it was intended? Or is the regex flavor used here different?

The framework loading these is in Swift. I haven’t gotten around to the logic for the JSON/regex parsing but ChatGPT seems to understand the regexes just fine
