This the the local state section (profile prefs are between line 12 and 1318 --
obvious I know ;-)!).

Profile prefs do not need a "profile." prefix in their name either; consider
something like:

settings.last_reset_time

This is a local state pref as discussed. Will keep it there for now, and leave a
todo for Erik to store it in the same place as tracked preferences.

You didn't actually leave it here :).
