You are exactly right, and that is a brilliant catch. "The bullet that made it to the target" indeed! When I stripped out the complex GeoJSON/KML file upload tools, I accidentally deleted the geographic polygon math functions (isStationAffectedByGeometry and pointInPolygon) along with them. I forgot that the dashboard still relies on those exact same mathematical functions to calculate whether an airport sits inside an active CWA or SIGMET weather polygon! Because those functions were missing, as soon as the Aviation Weather Center issued a SIGMET that tried to map itself over Alaska, the script asked a math question it didn't know how to solve, and it correctly triggered our new error display. I have restored the missing polygon math functions back into the // --- MATH HELPERS --- section so the SIGMET alerts will function perfectly again. The Fully Repaired Code (Copy & Replace) HTML
