I was able to bypass some of the steps in recreating the
data from scratch. Using s.to.rast on pre3 sites maps I
successfully created 5.0.2 raster maps that have the right
properties (values as expected, no more huge negative
numbers, etc.)

I am not sure I understand what is meant by "maps ...
created in text mode."  Text mode in GRASS?  The raster maps
were in any case floats or doubles, not integers.

Anyway, I think that I have resolved the problem
(functionally) but I remain a bit puzzled by what happened.

My thanks to the many grasslist participants, especially
Glynn, Roger, and Moritz who contributed ideas and
solutions.
