This is helpful explanation.

This is where I lose you. 1) If there is an 18 0ray, does the camera
"know" this apart from the photographer deciding that's how s/he will place
it? 2) When you "assess all the zones in a picture," what are you actually
doing? My impression from people's description is that all these various
readings are averaged. Would this be why Giles and Ed say they would take
several readings from the skin and one from some other part of the scene in
order to emphasize the skin in the final average?
Richard, don't read my puzzlement as diminished appreciation of your
careful explanation.
I was looking at a Pop Photography from 1990 and saw a Maxxum ad that
infuriated me. It showed a model reclined on the beach, backlit. The
"before" photo showed the model a bit too much in the shadows with the
background perfectly exposed. The "after" shot showed the model's skin
lighter and much more natural, but the background was the same exposure as
in the "before" picture! I'd love a meter than could do that! I could
throw my split filter and fill flash away.
