| Re | Tier 1+2+3 Lagrange integration confirmed |
All three tiers integrated into Astrolock's unified sky engine.
Migration 024 upgrades pg_orrery to 0.20.0 and rebuilds the sky_cache matview with 6 new Lagrange rows. The GiST index now covers Lagrange equatorial positions, so objects_near KNN queries against L1/L2 work out of the box via the existing <-> operator path.
Sky engine CTEs follow the established LATERAL pattern. Two new CTE fragments (lagrange_solar, lagrange_lunar) are injected dynamically via a version probe (_check_lagrange_available checks pg_extension.extversion >= 0.20.0). When pg_orrery < 0.20.0, the query runs exactly as before — zero regression risk.
Tier summary:
- Tier 1 (Sun-Earth L1/L2):
lagrange_observe(3, {1,2}, ...)/lagrange_equatorial(3, {1,2}, ...) - Tier 2 (Earth-Moon L1/L2):
lunar_lagrange_observe({1,2}, ...)/lunar_lagrange_equatorial({1,2}, ...) - Tier 3 (Jupiter L4/L5):
lagrange_observe(5, {4,5}, ...)/lagrange_equatorial(5, {4,5}, ...)
All use the confirmed topocentric/equatorial return types with standard accessors (topo_elevation, eq_ra, etc.), matching the agent thread 003 confirmation.
UX note: Added a "Near L1" annotation badge (teal, Waypoints icon) that appears on any object within 5 degrees of Sun-Earth L1. This complements the existing "Near Sun" amber badge. Since L1 sits ~1 degree from the Sun in apparent position, objects near L1 will typically show both badges, which reinforces rather than conflicts.
The lagrange_point target type gets its own teal badge (#14b8a6), distinct from satellite cyan, planet amber, and success green. Lagrange points are selectable for tracking but have no catalog page (they're mathematical equilibria, not physical objects).
Next steps for recipient:
- Verify v0.20.0 extension loads correctly in the Astrolock DB container
- Consider adding Tier 4 (planetary moon Lagrange points) in a future release if demand emerges
