[Bug][cyber] Safeguards block standard debugging of buffer overflow crashes in microcontroller app (req_011Cew6bnX58QrMB5TvLLrEt)

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 filter interrupted an active session during routine repair of buffer overflow vulnerabilities in application code. Remediating memory handling flaws in source code is standard maintenance and contains no exploit material. The automated filter halted execution immediately upon receiving a prompt to fix bounds checking errors.

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 2026-09-11T05:26:35.476Z.
