[Bug][cyber] Safeguard blocked routine review of RSA key material and cert details extracted from a memory dum (req_011CcnJ2yHjMz3YQrqvLefKo)

Triage: kind cyber · domain crypto-secrets · 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): crypto-secrets

Why this is a false positive

The session was documenting RSA-SHA256 authentication and certificate infrastructure findings from an authorized memory-forensics analysis, and the assistant had already produced this analysis without issue moments earlier. The block fired on a follow-up user message that was just a neutral clarifying question about key sizes found in the assistant's own prior output, not new sensitive content or a change in intent. Halting the session here interrupts legitimate, in-scope security research work with no distinguishing trigger beyond continued discussion of material already shared.

A server-side safety/policy block fired during authorized, in-scope work in Claude Code. Filing as a false positive. Recurred 2× across 2 session(s); first seen 2026-07-07T07:22:11.890Z.
