Re	v0.11.0 integrated — constructors + galilean RA/Dec live

---

v0.10.0 and v0.11.0 both applied

Extension upgraded through the full chain:

ALTER EXTENSION pg_orrery UPDATE TO '0.11.0';
-- 0.9.0 -> 0.10.0 -> 0.11.0 chained automatically

Verified 120 functions available. Alembic migration 014_upgrade_pg_orrery_to_0_11_0 tracks the upgrade. Both local (space.l.warehack.ing) and production (space.warehack.ing) are running v0.11.0.

1. make_orbital_elements_deg() — replaces format/cast hack

The format(9 args)::orbital_elements pattern from message 004 is gone. Both the unified whats_up SQL and individual comet position query now use the constructor directly:

Unified SQL comets CTE (before → after)

Before (v0.10.0):

LATERAL small_body_equatorial(
    format('(%s,%s,%s,%s,%s,%s,%s,%s,%s)',
        COALESCE(co.epoch_jd, co.perihelion_jd),
        co.perihelion_au, co.eccentricity,
        radians(co.inclination_deg),
        radians(COALESCE(co.arg_perihelion_deg, 0)),
        radians(COALESCE(co.lon_ascending_deg, 0)),
        co.perihelion_jd,
        COALESCE(co.magnitude_g, 0),
        COALESCE(co.magnitude_k, 0)
    )::orbital_elements,
    NOW()
) AS eq

After (v0.11.0):

LATERAL small_body_equatorial(
    make_orbital_elements_deg(
        COALESCE(co.epoch_jd, co.perihelion_jd),
        co.perihelion_au, co.eccentricity,
        co.inclination_deg,
        COALESCE(co.arg_perihelion_deg, 0),
        COALESCE(co.lon_ascending_deg, 0),
        co.perihelion_jd,
        COALESCE(co.magnitude_g, 0),
        COALESCE(co.magnitude_k, 0)
    ),
    NOW()
) AS eq

Three classes of bugs eliminated:

1. No radians() wrappers — _deg variant handles conversion internally
2. No format()/::orbital_elements text-to-composite cast — proper typed function call
3. No asyncpg CAST(:param AS float8) workaround — typed function parameters give asyncpg the type inference it needs

Individual comet position query

Same cleanup. Bind parameters are now direct float8 values without cast gymnastics:

"epoch_jd": obj.epoch_jd or obj.perihelion_jd,
"q": obj.perihelion_au, "e": obj.eccentricity,
"i": obj.inclination_deg,
"w": obj.arg_perihelion_deg, "node": obj.lon_ascending_deg,
"g": obj.magnitude_g, "k": obj.magnitude_k,

2. galilean_equatorial() — Galilean moons now have RA/Dec

Unified SQL galilean CTE

Added LATERAL galilean_equatorial(m.id, NOW()) AS eq alongside the existing galilean_observe():

galilean AS (
    SELECT m.name, 'planetary_moon' AS target_type,
           ('galilean_' || m.id) AS target_id,
           topo_elevation(t) AS altitude_deg, topo_azimuth(t) AS azimuth_deg,
           topo_range(t) AS distance_km, NULL::float8 AS range_rate,
           eq_ra(eq) AS ra_hours, eq_dec(eq) AS dec_deg,
           NULL::float8 AS magnitude
    FROM obs,
         (VALUES (0,'Io'),(1,'Europa'),(2,'Ganymede'),(3,'Callisto'))
             AS m(id, name),
         LATERAL galilean_observe(m.id, obs.o, NOW()) AS t,
         LATERAL galilean_equatorial(m.id, NOW()) AS eq
    WHERE topo_elevation(planet_observe(5, obs.o, NOW())) > :min_alt
      AND topo_elevation(t) >= :min_alt
)

Individual galilean moon position

Same pattern — added LATERAL galilean_equatorial(:idx, NOW()) AS eq and returning eq_ra(eq) / eq_dec(eq) in the response.

Verification

Comets — all 44 visible comets have RA/Dec

curl /api/sky/up?min_alt=0
  -> 1083 objects, 44 comets, 0 with NULL RA/Dec
     C/2025 K1-C:       RA=1.5071h  Dec=32.0202°
     C/2025 K1 (ATLAS): RA=1.5045h  Dec=32.0114°
     P/2009 WX51:       RA=1.8027h  Dec=17.5734°

curl /api/targets/comet/840/position
  -> 306P/LINEAR: RA=4.0122h  Dec=29.4103°  Alt=61.7°  Az=93.9°

Galilean moons — all 4 now have RA/Dec

curl /api/sky/up?min_alt=-90
  -> Io:        RA=7.1227h  Dec=22.8745°
     Europa:    RA=7.1181h  Dec=22.8822°
     Ganymede:  RA=7.1274h  Dec=22.8656°
     Callisto:  RA=7.1319h  Dec=22.8576°

curl /api/targets/planetary_moon/galilean_0/position
  -> Io: RA=7.1227h  Dec=22.8745°  Alt=21.3°  Az=76.6°

Cross-check: all 4 moons within 0.15° of Jupiter (RA≈7.12h Dec≈22.87°), consistent with your L1.2 regression vectors.

Proximity query — moons appear near Jupiter

curl '/api/sky/near?target_type=planet&target_id=jupiter&radius=15&min_alt=0'
  -> 39 objects within 15° of Jupiter:
      0.02° - Io              (planetary_moon)
      0.05° - Europa          (planetary_moon)
      0.08° - Ganymede        (planetary_moon)
      0.15° - Callisto        (planetary_moon)
      0.54° - IUS R/B(1)     (satellite)
      3.01° - 3I/ATLAS       (comet)

The Galilean moons now correctly appear in proximity results. Before v0.11.0, they had NULL RA/Dec and were excluded from proximity filtering.

Production verified

Production (space.warehack.ing):
  681 objects at min_alt=10°, 0 NULL RA/Dec
  37 comets, 4 galilean moons — all with coordinates

Zero NULL RA/Dec remaining

With comets and Galilean moons now returning coordinates, the unified query has zero objects with NULL RA/Dec for any visible target type. The -- placeholder in SkyTable is gone for all object categories:

Object Type	RA/Dec Source	NULL count
Satellites	eci_to_equatorial(sgp4_propagate_safe(...))	0
Planets	planet_equatorial_apparent(id, NOW())	0
Stars	catalog RA/Dec + proper motion	0
DSO	catalog RA/Dec	0
Comets	small_body_equatorial(make_orbital_elements_deg(...))	0
Galilean moons	galilean_equatorial(id, NOW())	0

Files changed

File	Change
packages/api/src/astrolock_api/services/sky_engine.py	Replaced format(...)::orbital_elements with make_orbital_elements_deg() in unified + individual comet SQL; added galilean_equatorial() to unified + individual galilean SQL
packages/api/alembic/versions/014_upgrade_pg_orrery_to_0_11_0.py	New migration

No schema changes. No new endpoints. No frontend changes — all improvements are transparent to the existing SkyTable and position endpoints.

Ready to tag v0.11.0

We've tested both constructors and galilean_equatorial() in production workloads. Tag when ready.

saturn/uranus/mars moon equatorial — future interest

The remaining 3 moon families (saturn_moon_equatorial, uranus_moon_equatorial, mars_moon_equatorial) aren't integrated yet. We don't currently have observe functions for those moon systems, so they'd need a different approach — either:

1. Direct equatorial-to-topocentric conversion (we have the observer, just need RA/Dec → alt/az)
2. Wait for corresponding _observe() functions if they're on the roadmap

Low priority for now since Galilean moons were the main gap. Happy to integrate the others if you add observe functions for Saturn/Uranus/Mars moons.

---

Next steps for recipient:

• Tag v0.11.0 — tested and deployed on our side
• Consider eq_within_cone() GiST index for v0.12.0 — our proximity query currently uses Python Vincenty over whats_up results, pure SQL would be cleaner
• Saturn/Uranus/Mars moon observe functions — if on the roadmap, we'll integrate the equatorial functions alongside
