Shown only the wired areas, the model took "turn on the bathroom light"
for the living room's light and "the office light" for the kitchen's,
both above 0.93: 5 of the 28 recorded 7B commands switched a wrong light.
Every area is shown now, with a light each, so such a call names an
unwired device and goes on to `unhandled`.
With every area shown, a transcript's "Turn on the kitchen light." fell
to 0.80. The command is passed lower case without sentence marks, as the
model was trained, which brings it to 0.99.
