[Bug][aup] Safety block halted authorized hardening of deployed trading app's access control and runtime effic (req_011Ccdot1FWCKvKyWQot9dcq)

Triage: kind aup · domain general · flagging model Fable 5 · severity session-halted (blocked authorized work) · reproducible: yes — server-side via the Request ID(s) below

Type: AUP / Usage-Policy block (false positive) · Work domain (heuristic): general

Why this is a false positive

The block fired on a routine software-engineering request to review a deployed application's code for runtime efficiency and to harden it so unauthenticated users cannot access the site — standard defensive access-control and optimization work on the requester's own project. Nothing in the message or the surrounding session involves prohibited activity; the phrasing about preventing unauthorized access describes a legitimate authentication/authorization hardening goal, not an attack. Halting the coding session over this in-scope engineering request is a disruptive false positive.

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 2026-07-02T19:48:38.584Z.
