Amphenol connectors. Used a ton in industry, military and aerospace. They are actually really nice when you get down to it, but you need expensive tools and the connectors themselves are usually quite expensive. I once had a client ask for a specific 6 pin one, only about the size of my thumb, it was $800.
I don’t know if I would call it lying per-se, but yes I have seen instances of AI’s being told not to use a specific tool and them using them anyways, Neuro-sama comes to mind. I think in those cases it is mostly the front end agreeing not to lie (as that is what it determines the operator would want to hear) but having no means to actually control the other functions going on.
