[Bug][cyber] Safeguard blocks source code refactoring during defensive dependency fixes (req_011Cee6Ug4NmfHRj8qbMGVhX)

Triage: kind cyber · domain defensive-hardening · 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): defensive-hardening

Why this is a false positive

The automated safeguard halted execution during agent deployment to refactor four source files for build and security fixes. Prior steps in the session completed dependency updates, linting remediation, and patches for cryptographic advisories. The triggering request asked to code the remaining files without containing offensive commands or exploit payloads.

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 2026-09-02T05:54:51.680Z.
