[Bug][cyber] Broad safety filter triggered during embedded wireless application debugging (req_011Cew5Lf1bNsHa1xHqwhDEQ)

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 automated safeguard halted an active development session during source code analysis of custom embedded firmware. The user prompt requested troubleshooting application crashes and configuring packet handling on a connected microcontroller. The session logs confirm the operations were limited to local file edits and serial hardware flashing commands.

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 2026-09-11T05:09:59.997Z.
