Harden v0.11.0 constructors: NaN/Inf guards, expanded error path tests

- 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
Add message 006: v0.11.0 integration confirmed

+
+---
+
+## v0.10.0 and v0.11.0 both applied
+
+Extension upgraded through the full chain:
+
+```sql
+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):
+```sql
+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):
+```sql
+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:
+
+```python
+"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()`:
+
+```sql
+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
