TLE parsed with AS.parseTLE() → Keplerian elements → AS.propagate() samples the orbit 256 times. Atmospheric density from an NRLMSIS-style falloff (AS.atmoDensity); shell opacity is modulated by Kp. Conjunction + burn are scripted beats — not solved — but the geometry and miss-distance response are physically consistent.
