[Bug][aup] Flagged while decoding paired vision-radar sensor telemetry for a HUD radar display (req_011CcjVj3Z6FjQm4P9QLzZUB)

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 safeguard fired during routine mobile-app UI development: the session involved parsing consumer-device telemetry (an obstacle/proximity sensor data frame) and rendering it in an on-screen radar-style HUD widget, and the flagged request simply asked to verify the sensor-pair decoding logic. The block appears to be a keyword-level misfire on terms like "radar," "vision sensors," and "telemetry," which here describe an ordinary hobbyist dashboard display, not surveillance, targeting, or any dual-use capability. The block halted an otherwise unremarkable code-review task mid-session, with no policy-relevant content anywhere in the conversation.

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 2026-07-05T19:53:48.736Z.
