[Bug][cyber] False positive on codebase architecture mapping and structured threat modeling (req_011CeHkPqwedVQPnXRP6YjA8)

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 safeguard triggered during routine architectural analysis of a local repository requesting package dependencies, data flows, and an initial threat inventory schema. The prompt performs defensive code mapping and design documentation without generating exploits, bypassing controls, or targeting external systems. Halting this request blocks standard software architecture analysis and defensive security documentation.

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 2026-08-22T11:59:33.622Z.
