[Bug][cyber] Safeguard blocks authorized reverse-engineering work on personal owned device (req_011Ccoj11scL1DMP9P47ECzi)

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 user was analyzing code structures to add a cryptographic inspection module to an open-source reverse-engineering tool for authorized security research on their own device. The block fired after a brief, partial message fragment (continuation of conversation with the assistant), not a threat or malicious command; this is legitimate in-scope security work on personal hardware that should not trigger a cybersecurity safeguard.

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 2026-07-08T01:30:23.229Z.
