Therefore they are spelled identically, as far as the Code is concerned, 
and accordingly "prevailing usage" either applies to *all* the 
alternatives, or *none*. Changing an epithet to match a gender is not 
changing its spelling, otherwise the forms could not be identical, could 
they?

The correct original spelling is, effectively, *simultaneously* pulcher, 
pulchrum, or pulchra, rather than any one of these - until it is placed 
in combination with a genus name. Very much like Schrodinger's Cat.

They're identical, by definition, so it doesn't matter what gender the 
genus is as far as the Code is concerned; generic assignment is a 
temporary thing, and the Code is written so as to acknowledge this.
