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 broad cybersecurity filter triggered during routine cloud backup curation while selecting specific project files for synchronization. The active session involved calculating local directory storage bounds and selecting folder subsets for remote transfer. The prompt history consists strictly of file management operations and contains no exploit material or attack vectors.

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 2026-08-30T21:35:31.799Z.
