Integrate IAU 2000B nutation (~9 arcsec) into the solar system observation
pipeline via precess_and_nutate_j2000_to_date(). Affects all planet, star,
moon, and small body RA/Dec and az/el values. Satellite SGP4/TEME pipeline
unchanged.
Add make_equatorial(ra_hours, dec_deg, distance_km) constructor to replace
error-prone text literal casts.
Add 8 rise/set prediction functions (planet_next_rise/set, sun_next_rise/set,
moon_next_rise/set, sun_next_rise/set_refracted) using bisection algorithm
adapted from satellite pass prediction. Returns NULL for circumpolar and
polar night edge cases.
Fix DE fallback test fragility: replace exact float equality with tolerance
comparisons to handle GCC LTO inlining divergence across translation units.
132 -> 141 SQL objects. 22 -> 24 regression suites. All 24 passing.
- Add validate_orbital_elements_args() with isnan/isinf checks for all
7 propagation parameters (epoch, q, e, inc, omega, node, tp); h_mag
and g_slope exempt (NaN is valid sentinel for "unknown magnitude")
- Deduplicate validation between make_orbital_elements() and _deg()
- Update SQL COMMENTs to clarify geometric vs apparent coordinates
- Add NaN/Inf rejection tests (q, e, epoch, Inf inclination)
- Add NaN H/G acceptance test (sentinel value)
- Expand error path coverage to all 4 moon families + negative body_id
- All 20 regression suites pass
6 new SQL functions (114 -> 120):
- make_orbital_elements(): construct from 9 floats, angles in radians
- make_orbital_elements_deg(): same with angles in degrees, matches
text I/O convention and typical catalog column layouts
- galilean_equatorial(): geocentric RA/Dec for Io/Europa/Ganymede/Callisto
- saturn_moon_equatorial(): geocentric RA/Dec for Mimas through Hyperion
- uranus_moon_equatorial(): geocentric RA/Dec for Miranda through Oberon
- mars_moon_equatorial(): geocentric RA/Dec for Phobos/Deimos
Constructors requested by astrolock-api to replace fragile
format(9 args)::orbital_elements cast pattern. Moon equatorial
functions fill the last NULL RA/Dec gaps in their unified sky query.
All 20 regression suites pass.
