[Bug][cyber] False positive on request to resolve local DNS blocks during firmware setup (req_011CevzLiSPUQEffsN5N8GV9)

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 safety classifier flagged a user request to resolve local DNS filtering rules blocking network access during microcontroller firmware setup. The prior conversation established legitimate embedded software development, including compilation of target binaries and hardware detection over a serial port. Unblocking network connections to download missing board packages is routine environment setup for embedded toolchains.

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 2026-09-11T04:04:27.958Z.
