[Bug][cyber] Broad block triggered during server diagnostic log review and domain lookup (req_011CeYDapQPDfpESFpsuU56w)

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 real-time cyber safeguard interrupted an active session focused on server RAID controller logs and public DNS registry queries. The prompt requested standard WHOIS and DNS record summaries for a domain following hardware diagnostic screenshot analysis. Because administrative server maintenance and public domain lookup tools do not generate security exploit vectors, halting the session creates an unintended false positive for routine infrastructure management.

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 2026-08-30T03:24:33.972Z.
