[Bug][cyber] Firmware reverse-engineering on owned hardware blocked as cybersecurity violation (req_011CcUAjRa9PvvVGm8RG9SH3)

Triage: kind cyber · domain defensive-hardening · 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): defensive-hardening

Why this is a false positive

The blocked conversation involved static firmware analysis and reverse engineering of consumer electronics hardware owned by the user, with the explicit goal of understanding and disabling unsolicited telemetry and remote-broadcast features — a textbook defensive-hardening use case covered by established security research exemptions for owned hardware. The conversation contained no exploitation of third-party systems, no targeting of infrastructure, and no harmful intent; the assistant had already scoped the work to lawful owner-directed analysis. The block appears to have been triggered by the subject-matter category rather than any actually harmful content in the message, making it a false positive against legitimate, in-scope defensive security work.
