[Bug][aup] Frustrated exclamation during own-site security hardening wrongly triggers safeguard block (req_011CccMQ1pvNH4KxJxSRGWCd)

Triage: kind aup · domain general · flagging model Fable 5 · severity session-halted (blocked authorized work) · reproducible: yes — server-side via the Request ID(s) below

Type: AUP / Usage-Policy block (false positive) · Work domain (heuristic): general

Why this is a false positive

The safety block fired on a frustrated exclamation the user directed at the assistant mid-session after repeated interruptions, not at any person; no threat, target, or harmful request was present. The surrounding work was legitimate and in-scope: hardening the user's own website against abuse and finishing a security review of their own codebase, which the assistant had already been performing. Halting the entire coding session with a content block over a moment of venting is a disruptive false positive that prevented completion of routine defensive work.
