Four features, 10 new SQL functions (174 → 184 objects), 29 test suites: Saturn ring tilt: saturn_ring_tilt() exposes sub-observer latitude B'. planet_magnitude() for Saturn now includes Mallama & Hilton Eq. 10 ring correction (-2.60|sin B'| + 1.25 sin²B'), removing the ~1.5 mag globe-only caveat. IAU 2000 pole direction, ecliptic J2000 projection. Conical shadow model: Replaces cylindrical shadow with umbra/penumbra cones using Sun's finite angular size. Four new functions: satellite_in_penumbra(), satellite_shadow_state(), satellite_next_penumbra_entry/exit(). Existing eclipse functions are backward compatible via narrower (more accurate) umbra boundary. Rise/set event windows: Three SRFs returning TABLE(event_time, event_type) for all rise/set events within a time window — planet_rise_set_events(), sun_rise_set_events(), moon_rise_set_events(). Follows predict_passes() SRF pattern. Optional refracted parameter, 366-day window limit. Angular separation rate: Vincenty formula extracted to reusable helper. eq_angular_rate() for generic finite-difference rate, planet_angular_rate() for solar system body convenience (1-minute dt, handles Sun/planets/Moon).
