[Bug][cyber] Safeguard blocks repository search for hardcoded backend placeholder data (req_011CePCSbaat7V2XqD2Todqh)

Triage: kind cyber · domain offensive-pentest · 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): offensive-pentest

Why this is a false positive

The safeguard halted execution while searching backend Go source files for hardcoded placeholder data. Inspecting source code for sample data or mock responses does not invoke network targets or execute payloads. The prompt consisted strictly of read-only string pattern matches across local repository files.

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 2026-08-25T09:04:06.276Z.
