A sweep for the same pattern found more answers presented as current and complete: launches and satellite orbits served from a stale proxy cache, a regional aircraft fallback read as worldwide, license plate cameras trimmed or partly loaded, and a radio directory of popular stations read as every station. The launch and satellite sources now report the proxies' stale markers, and each answer says what it covers.
