[Bug][cyber] Safety block triggered by frustrated exclamation, halting unrelated legitimate session (req_011CcmDoWR86zvi6RECb7hB9)

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 brief frustrated exclamation directed at the assistant mid-session, with no other party addressed and no cyber-related content present. Surrounding work in the session was legitimate and unrelated to security topics, yet the block terminated the entire session rather than the single message, forcing a restart. Flagging informal venting as a cybersecurity safety concern is a false positive that disrupts normal, in-scope work.
