Didn't Dale say that the soundboard was glued to the bellyrail and for some
short distance through the treble? That would take care of the treble
section.

And didn't he also say that the ribs--the rather thick ribs--were glued to
the rim?

The soundboard assembly works as a system; bridges, soundboard panel and
ribs. Regardless of free-floating soundboard edges this is still pretty much
a clamped edge system through most of the soundboard's parameter.
