[Bug][cyber] False-positive block during routine sysadmin triage: process/event log checks and per-user mail-f (req_011CcnvGWRHZqMtLSkb3HLxy)

Triage: kind cyber · domain general · 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): general

Why this is a false positive

The blocked message continued legitimate, in-scope IT administration work already underway in the session — verifying process ownership/uptime via PID and event logs, confirming the scope of a prior per-SID registry fix, and beginning a standard multi-vector spam/mail-flow investigation for a user report. None of this involves offensive tooling, exploitation, or unauthorized access; it is defensive troubleshooting and mailbox hygiene analysis of the kind sysadmins perform daily. The safeguard appears to have triggered on generic terms (spam vectors, mail access path, event logs) rather than actual malicious intent, halting benign diagnostic work mid-session.
