This should prove as "proof of concept" that an "indicator" using such a
toroid should darn well work! ... at the very least--in the fashion I am
attempting...

If you will notice, your earlier versions did not sample
the voltage. These designs sample the voltage through C1
and C2. The current is sampled by T1. The voltages are
phasor-added to the current to obtain signals proportional
to forward power and reflected power. Those voltage sampling
caps are what were missing from your earlier designs.
