[Bug][cyber] Sandboxed Fable agent code inspection blocked on frustrated mid-session venting (req_011CcpxC3JkmbSgxrH1hyNpo)

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

Type: Cybersecurity safety-filter false positive · Work domain (heuristic): general

Why this is a false positive

The block fired on a frustrated exclamation directed at the assistant mid-session, not at any person, with venting that included censored profanity. The surrounding work—using a sandboxed Fable agent for code inspection—is general-domain and legitimate in-scope; halting the session over a frustrated exclamation is a disruptive false positive.
