Ok, not everything is going to have CA3089 or SSM2047, and that’s ok, but I expect to find CD4013 (for example) without issues. Your priorities may differ!

Trust, but verify.

Years ago at a previous job I had the CAD team layout a board for me
that included a common CMOS 4000 series part (I think it was a quad
NOR???)  So common and so widely known, the CAD engineer used the
vendor-supplied library and footprint.  No need to check, it was bound
to be right.  Right?

The vendor library was wrong.  And I'm talking about the kind of
vendor who charged per seat per year.  Eye-watering amounts of

Fortunately one of our skilled PCB technicians was able to pull up
some of the pins (14-pin surface mount package, of course) and
