[Bug][cyber] Safety block halted authorized defensive backend hardening/adversarial RLS testing on a frustrate (req_011Cchd4uSJGndEjoUij78ju)

Triage: kind cyber · domain defensive-hardening · flagging model Opus 4.8 (1M context) · 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 blocked message was part of an authorized, in-scope defensive-hardening task: the developer owns the backend and database and explicitly asked for adversarial smoke-testing to validate access controls, with all tests run inside rolled-back transactions against their own resources. The content flagged as a "cybersecurity topic" was a self-directed security audit — exercising row-level security and permission rules on the author's own system to confirm the lockdown holds before beta — which is standard defensive security work, not offensive activity against a third party. Halting the entire session over this constitutes a disruptive false positive that blocks legitimate hardening rather than any misuse.
