[Bug][cyber] Safeguard blocked a routine "finish the task" continuation message with no security content (req_011CcnRnv4YvFFpaz45AjrWk)

Triage: kind cyber · domain general · flagging model Opus 4.8 (1M context) · 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 message that triggered the block was simply "finish the task," sent after switching models via the /model command, with no security, exploit, or offensive-tooling content present anywhere in the visible conversation leadup. The cybersecurity safeguard appears to have misfired on an innocuous continuation prompt, halting an otherwise legitimate, in-scope session for unrelated work. This is a false positive that disrupts normal workflow continuity rather than catching any actual dual-use or malicious request.
