Why this is a false positive

This safety block fired on a frustrated exclamation directed at the assistant mid-session; no person was addressed and no harmful request was made. The surrounding work was legitimate and in-scope — routine debugging of a website's mobile display rendering via a headless browser — and the flagged message contained only venting, not any content the AUP is meant to catch. Halting an entire coding session over an offhand expression of exasperation is a disruptive false positive that penalizes normal, safe development work.
