More generally, the model shouldn't make assumptions about the

view. In this case, the fact that the fader 'ends' at -100 dB,

and that consequently this value should be taken to mean 'off',

is an implementation detail of the view. The model should allow

gains below -100 dB (up to some reasonable value).
Anyway, for me it's time to go to sleep. And seeing your TZ

and knowing the date I suspect a turkey is waiting for you :-)
