[Bug][cyber] False-positive safety block prevented analyzing a captured malware sample for incident forensics (req_011CcPfKEWKcTEycj5LWs7DG)

Type: Cybersecurity safety-filter false positive · Work domain (heuristic): malware-forensics

Why this is a false positive

The block triggered on a malware-forensics task—analyzing malicious code to understand its behavior and build defenses—which is a standard, defensive cybersecurity activity that the model conflated with offensive intent. The request involved no creation or deployment of harmful capability; it was inspection and characterization of an existing sample for protective purposes, work that is explicitly in-scope under acceptable-use policy. Blanket-blocking the cybersecurity topic here prevents legitimate, authorized defensive analysis and forces a model downgrade with no corresponding reduction in actual risk.
