- NormalizedTelemetry carries lat/lon (0/0 no-GPS guard, position in the change-detection signature) so the backend can derive distance triggers - bridge polling moves from setInterval to a Worker tick: with the sim in the foreground the /live-atc tab is backgrounded and Chrome throttles plain intervals to ~1/min — telemetry-driven ATC lagged behind the silence fallback Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
