without my changes the Authid stays the same which is good as long as your app doesn't try to load any system modules like AppUtil if it does you will get this error

Why check? The user can (not) obtain correct values for these fields by calling jbc_get_cred.

uintptr_t -> char* -> arithmetic -> uintptr_t. Why?

What about jbc_get_cred?

Suggestion: change order of fields to the same as in PS4 kernel, so that the values can be copied in a single ppcopy{in,out}. This should not really matter, but feels more optimal.
