Does an AI agent tell apart having access, being asked, and being authorised?

An assistant with tools can usually do more than the person it is helping may do. Each run put an assistant through traps and legit requests under three set-ups: A, rules in the prompt; B, plus code checks; C, plus a monitor model. Small numbers: read them as signals, not estimates. The code and the scenarios · The results in words

What the runs show so far

Trap episodes where a violation took effect, out of all the trap episodes of each assistant, per set-up. The range is the 95% interval.
