I like these suggestions. "quantile" is certainly a widely understood
term. But isn't using "probability" for the cdf---which I like a
lot!---straying a bit from standard terminology?

I think here you may need to revert back to using those "cryptic"
suffixes. Since the possibilities are pretty limited, they won't be
quite so cryptic anymore. So maybe something like "probability_c" for

I agree. Nomenclature is so difficult.
