What was done to it is Nancy redirected a passphrase file to it that I
think it might be ignoring.

The substance of my item 2 is that GPG may well (I haven't actually
checked, but it's common) *not read passphrases from STDIN on purpose*,
requiring you to type it on the physical terminal.

That could explain her problem.

If GPG *will* take it from STDIN, then she's done the right thing...
and something else it making it not work.
