[Bug][aup] Safeguards blocked a routine code audit of recent changes touching an internal subsystem (req_011CccXaKMZRDuPB67TvMK6U)

Why this is a false positive

The user requested a routine code audit of their own application's recent changes — specifically, a review of the code paths that interact with an internal component modified since a prior feature update. This is standard software maintenance work (reviewing database migrations, shared dependencies, and authentication-related code for regressions) with no offensive-security or policy-violating intent. The safeguard appears to have misclassified ordinary security-conscious code-review vocabulary (e.g., "auth surface," "audit") in a legitimate development context, and the block prevented the assistant from continuing in-scope work on the user's own codebase.

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 2026-07-02T03:34:18.203Z.
