Why this is a false positive

This safety block fired on legitimate, in-scope work and returned a false positive: the flagged message was part of an ongoing authorized technical session, not a request for harmful capability. The classifier appears to have keyed on surface cybersecurity terminology rather than intent, halting the entire session over benign, professional content. A content filter that aborts a whole working session on a topical keyword match — with no actual harmful request present — is a disruptive false positive that warrants tuning toward intent-based evaluation.
