How do we safely determine the passaggio points of a young male singer? Can they change with maturity? If they can shift over time, how reliable is it to depend on them as early indicators of voice classification?
What, exactly, should one be listening for in identifying the registration pivotal points of a male voice?

I think I have a fair handle on female registration. But what do registration events sound like in the male voice? How can you tell when a passaggio pivotal point has been reached?
YET ANOTHER RELATED QUESTION
Why do you designate the passaggio points of male voices over a wider range than those of female voices? For example, you indicate a number of specific pitch designations as passaggi for the several tenor categories, and quite a few for baritones and basses. But you show only a semitone or whole-tone difference among soprano and mezzo-soprano categories, and only about a half-step difference between the mezzo and the contralto.
