All,
I have looked at the Orbit 94 ATS, and I approve.
PL commands match the STF per Ken's script (thanks again) and
take place at sensible times compared to the ascending and desceding
times.
Nothing else is going on during the -Lo gain test.
Contact schedules line up between the SC and the ground scheduled time.
There's more than an hour between maneuver/contact and start
of battery cell balancing, and no eclipse near there.
The maneuver points us in a safe direction at the time of the
burn, and at the ascending and descending times for the next orbit:

The command set looks good to me. I'm still curious about why
the .ccvr file declared an unknown state for the PL at the beginning
of the orbit - this orbit seems just like all the others in that
respect.
Orbit 95 will have O-mode operations and an IBEX-Hi gain
test, so stay tuned.
