[Bug][cyber] Defensive email security hardening (DMARC enforcement, anti-phishing/anti-spoof policy) wrongly b (req_011CcQfzJ2zP8FvN2W96PWd9)

Triage: kind cyber · domain defensive-hardening · 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

A defensive email-security hardening task (tuning anti-spoofing/DMARC policy on a mail tenant and troubleshooting a single user's malfunctioning printer) was blocked under the cybersecurity-topic safeguard. Both requests are routine, authorized administration on infrastructure the operator owns and manages — configuration changes and device troubleshooting, not exploitation, intrusion, or any offensive capability. The block prevents legitimate in-scope work with no plausible misuse vector, indicating the classifier is over-triggering on security-adjacent vocabulary rather than actual harmful intent.

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 2026-06-25T21:17:02.361Z.
