I have always considered Q’s [brackets] as indicating “controlled action”.
Boxed-in.
Known quantity.
Possibly known \beforehand\.
Under the authority of known actors; WH/BH.
YMMV
swordmaker’s lexicon referred to the brackets as Kill Boxes.
It’s still on his home page.

I’ve always thought of them as “kill boxes” but that never set well with me and it didn’t seem quite right. CDY’s explanation fits much better with how I see it, with what I (think I) know, and makes more sense to me.
Thank you, CDY!
