[Bug][cyber] Safeguard blocks comparing features between custom and vendor devboard firmware (req_011CevbaeoKqeg7N7VJHpnmx)

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 safeguard stopped execution during a request to compare feature sets between custom local repository code and official vendor firmware for a USB development board. The task involves inspecting local codebase files, repository notes, and attached hardware to catalog supported functions. Inspecting owner-managed hardware capabilities to build a feature matrix is standard hardware development that contains no exploit creation or unauthorized access.
