This is where your logic goes wrong, in our perfect idealized
"transformer" with the secondaries connected in the "bucking"
configuration, and no DC in the primary, the inductance is already as
low as it can get, how can the inductance be less than zero when the
"transformer" is saturated?

Not talking transformer - but rather saturable reactor. Drawn similar -
but windings, core, etc. are different - and they don't interact the
same as a transformer. and I still think that's what's in the S/W. I
think if we get a side shot of the construction - we'll see three
leggs... maybe not.

Bucking - when talking about saturable reactors - bucking means one
winding reversed so that it's induced field is opposite the other
winding's field *when they meet at the control winding*. That would
translate to aiding as looking at the two load windings (but since
they're usually in a three legged config - the two don't interact as
such)... So yes - *one* of us has to "adjust" our perspective....

Again - look at the illustration at the bottom of this page::::

See the "buck" at the control winding - Note that this is "aid" at the
other load winding? Just the perspective it's viewed from, John.
