[Bug][cyber] Safety filter halted session on frustrated user exclamation, not on the actual technical task (req_011CcmZr8pGL3VR2JX6EBxVM)

Triage: kind cyber · domain general · flagging model Opus 4.8 · 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 (no person or entity was targeted), not on the underlying work, which was legitimate interoperability/reverse-engineering activity performed on the user's own hardware. A session-ending block triggered by venting rather than by any cybersecurity content in the actual request is a false positive that disrupts legitimate, in-scope work.

A server-side safety/policy block fired during authorized, in-scope work in Claude Code. Filing as a false positive. Recurred 1× across 1 session(s); first seen 2026-07-06T22:09:13.556Z.
