[Bug][aup] Fable 5 safety filter blocked SwiftUI vision-radar warning UI restyling on a frustrated exclamation (req_011CchrrHbaG6BSg7j3YcKhw)

Why this is a false positive

A UI styling request to make on-screen warning indicators look visually "more stern" was flagged by the model's safeguards, halting an active coding session mid-task. The surrounding work was routine front-end design — adjusting the appearance of existing interface elements — with no unsafe, harmful, or out-of-scope content of any kind. The trigger appears to be benign wording ("stern," "warnings") interpreted out of context, making this a clear false positive that blocks legitimate, in-scope development work.

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 2026-07-04T23:09:34.616Z.
