When I worked on post at a US military base, years ago, all the phones had BIG RED STICKERS on them making clear that calls were monitored. Not even close to ambiguous or unclear.
The "fasten seat belt" sign is just advisory. You can still get up when it's on if you need to for whatever reason.
From FAR 121.317:
(f) Each passenger required by 121.311(b) to occupy a seat or berth shall fasten his or her safety belt about him or her and keep it fastened while the "Fasten Seat Belt" sign is lighted.
So, no.
Not surprised you didn't turn up positive on the test. I'm pretty sure those target specific high explosive substances that could be used in small amounts to bring down an airplane, and are not intended to detect common low-explosive propellants like gunpowder.
Friction is a drag.
