This brings a new concept to me: how can a face be invalid in a specific
frame?  I thought a face either existed (globally) or not.  It can have
different "values" in different frames, but this is the first time
I hear mention of a face being *invalid* in a particular frame while
existing in other frames.

I think it would be better if we can get rid of this subtlety.
