> If, in the context of cooperating together, you say "should I go ahead?" and they just say "no" with nothing else, most people would not interpret that as "don't go ahead"

This most definitely does not match my expectations, experience, or my way of working, whether I'm the one saying no, or being told no.

Asking for clarification might follow, but assuming the no doesn't actually mean no and doing it anyway? Absolutely not.
