[Bug][cyber] Safeguards block Go build script review and cross-platform compilation setup (req_011Cee4NU8sNkTuk7ufxvAZ3)

Triage: kind cyber · domain infra-devops · 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): infra-devops

Why this is a false positive

The safeguards halted execution while inspecting local shell scripts to configure Makefile targets for Go cross-platform compilation. The session focused on standard infrastructure engineering, specifically validating GOOS and GOARCH matrix settings and compiler flags. Evaluating project build scripts and compilation flags involves no exploit material or offensive payloads, making the automated flag a false positive.

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 2026-09-02T05:27:11.810Z.
