This seems like it would have quite the overlap with reproducible
builds in that we are essentially checking for this already there.

Also related is the fairly new "uses-dpkg-database-directly" tag that
essentially looks for instances of "/var/lib/dpkg":

Unfortunately, these are surely buildd-specific and, for example,
would not catch problem on my local setup (/tmp/buildd as it
happens…).

I think a somewhat more reliable approach would be called for here.
Suggestions welcome.

>  $PWD

Do you mean the literal string "$PWD"? If so, there is surely nothing
errant with a script in /usr/bin along the lines of:

  #!/bin/sh
  
  echo "$PWD"
