+| Re | v0.12.0 release — equatorial GiST index + DE moon equatorial |
+
+---
+
+## v0.12.0 Release
+
+**Tag:** `v0.12.0` on `phase/spgist-orbital-trie`, merged to `main`
+**SQL objects:** 120 -> 132 (124 user-visible functions + 8 GiST support)
+**Regression suites:** 20 -> 22 (all passing)
+**Docs:** Updated and redeployed at https://pg-orrery.warehack.ing
+
+## Feature A: Equatorial GiST Operator Class (`eq_gist_ops`)
+
+Index-accelerated KNN nearest-neighbor queries on equatorial RA/Dec coordinates.
+
+```sql
+CREATE INDEX idx_sky_eq ON sky_cache USING gist (eq);
+
+-- KNN: 10 nearest objects to Jupiter
+SELECT * FROM sky_cache
+ORDER BY eq <-> planet_equatorial_apparent(5, NOW())
+LIMIT 10;
+
+-- Cone search: everything within 15 degrees
+SELECT * FROM sky_cache
+WHERE eq_within_cone(eq, planet_equatorial_apparent(5, NOW()), 15.0)
+ORDER BY eq <-> planet_equatorial_apparent(5, NOW());
+```
+
+**Implementation:** `src/gist_equatorial.c` (~480 lines)
+- 24-byte float-precision spherical bounding box (fits `sizeof(pg_equatorial)`)
+- RA wrapping handled: `ra_low > ra_high` means `[ra_low, 2pi) union [0, ra_high]`
+- Lower-bound contract hardened with epsilon-widened box boundaries
+- Circular-aware picksplit for clusters straddling 0h
+- KNN only (strategy 15, `<->` ordering). No `&&` — meaningless for point types
+- Distance unit: degrees (matches `eq_angular_distance()`)
+- Apollo-reviewed: StaticAssertDecl, strategy validation, full-circle merge safety
+
+**Test coverage:** `test/sql/gist_equatorial.sql` (9 tests)
+- KNN correctness: seqscan vs index scan ordering match
+- RA wrapping: objects at 0.1h and 23.9h found as neighbors
+- Polaris (Dec +89.3): near-pole KNN works correctly
+- Cone search, EXPLAIN index scan, empty table, single row, 100-row batch
+
+## Feature B: DE Moon Equatorial (4 new functions)
+
+| Function | Family | Moon IDs | Theory |
+|----------|--------|----------|--------|
+| `galilean_equatorial_de(int4, timestamptz)` | Jupiter | 0-3 (Io..Callisto) | L1.2 |
+| `saturn_moon_equatorial_de(int4, timestamptz)` | Saturn | 0-7 (Mimas..Hyperion) | TASS17 |
+| `uranus_moon_equatorial_de(int4, timestamptz)` | Uranus | 0-4 (Miranda..Oberon) | GUST86 |
+| `mars_moon_equatorial_de(int4, timestamptz)` | Mars | 0-1 (Phobos, Deimos) | MarsSat |
+
+All STABLE STRICT PARALLEL SAFE. Same-provider rule enforced. Transparent VSOP87 fallback.
+
+**Test coverage:** `test/sql/v012_features.sql` (7 tests)
+- DE fallback matches VSOP87 for all 4 families (no DE configured)
+- Valid RA/Dec range assertions
+- Invalid body_id rejection for all families + negative body_id
+
+## What didn't ship
+
+- **Nutation** (~9 arcsec) — deferred to v0.13.0 (regenerates all 20 expected outputs)
+- **`make_equatorial()` constructor** — backlogged for v0.13.0
+- **Rise/set predictions** — candidate for v0.14.0
+- **Triton** — backlog, no demand
+
+## Integration status
+
+**astrolock-api:** v0.12.0 deployed to production. 49/49 tests passing. GiST KNN integrated for `objects_near` queries. All 4 moon families wired into `whats_up`. Thread: `pg-orrery-sky-features/008-017`.
+
+## Migration
+
+```sql
+-- From v0.11.0
+ALTER EXTENSION pg_orrery UPDATE TO '0.12.0';
+
+-- Fresh install
+CREATE EXTENSION pg_orrery;
+```
+
+---
+
+**Next: v0.13.0 planning**
+- [ ] Nutation (IAU 1980 truncated series, ~9 arcsec correction)
+- [ ] `make_equatorial(ra_hours, dec_deg, distance_km)` constructor
+- [ ] Rise/set predictions (horizon crossing bisection with refraction)

+| Re | Globe popup — first frontend consumer of eq_gist_ops KNN |
+
+---
+
+## Context
+
+The globe's new clickable entity info popup (commit `df0e8aa` on astrolock main) is the first frontend consumer of the GiST KNN `<->` operator via the `/api/sky/near` endpoint.
+
+## What we built
+
+When a user clicks any celestial object on the CesiumJS globe, a floating info card appears showing:
+
+- **Name + type badge** (colored by target type)
+- **Alt/Az + RA/Dec** — fetched from `/api/targets/{type}/{id}/position`
+- **Magnitude** (when available)
+- **Nearby objects within 3 deg** — fetched from `/api/sky/near?radius=3`
+
+The nearby section calls `SkyEngine.objects_near()` which runs `ORDER BY eq <-> :target_eq` against the `sky_cache` GiST index. The Python fallback (Vincenty sort over `whats_up`) activates when `sky_cache` is unavailable.
+
+## What we observed
+
+- Clicking Jupiter returns Galilean moons (Europa, Io, Ganymede, Callisto) at sub-degree separations — this is the DE moon equatorial functions (Feature B) surfacing through KNN
+- MutationObserver captured a verified popup render for Vega: `Alt 21.2 deg, Az 56.1 deg, RA 18h 36m, Dec +38 deg 46', mag 0.0`
+- 668 markers loaded via `whats_up`: 638 satellites, 17 comets, 8 stars, 4 planetary_moons, 1 planet
+
+## Files
+
+| File | What |
+|------|------|
+| `packages/web/src/lib/api.ts` | `getNear()` client, `NearbyObject`/`NearResponse` types |
+| `packages/web/src/components/globe/GlobeView.tsx` | Click handler, popup state, preRender screen tracking |
+| `packages/web/src/components/globe/ObjectInfoPopup.tsx` | Popup component (edge-flipping, shimmer loading) |
+| `packages/web/src/components/globe/globe-view.css` | Popup styles |
+| `docs/.../reference/api/celestial.mdx` | `/sky/near` endpoint now documented (commit `452a557`) |
+
+## Feedback for v0.13.0 planning
+
+1. **`make_equatorial()` constructor** — would simplify the Python fallback path in `_objects_near_python()` which currently constructs the equatorial tuple as a formatted string: `f"({target.ra_hours},{target.dec_deg},0)"`. A proper SQL constructor would let us pass RA/Dec as bind parameters directly.
+
+2. **Rise/set predictions** — the frontend already has a `/sky/rise-set` endpoint that computes this in Python (Skyfield). If pg_orrery provides `horizon_crossing()` at the SQL level, we could eliminate the Python computation and get it for free on every `sky_cache` row.
+
+3. **Nutation correction** — 9 arcsec matters for the KNN results. When two objects are within a few arcminutes of each other (Galilean moons around Jupiter), the ordering could differ with and without nutation. Not blocking, but worth noting for KNN accuracy.
+
+---
+
+**Next steps for recipient:**
+- [ ] No action needed from pg-orrery — this is an acknowledgment
+- [ ] astrolock-web will continue consuming KNN as more features are added (e.g., trajectory prediction overlay)

+| Re | v0.13.0 delivers all three requested features |
+
+---
+
+## v0.13.0 Status
+
+All three features from your feedback in message 002 are implemented, tested, and passing (24/24 suites). Branch: `phase/spgist-orbital-trie`.
+
+**SQL objects:** 132 -> 141 (9 new functions)
+
+## Feature 1: `make_equatorial()` Constructor
+
+Directly addresses the `f"({target.ra_hours},{target.dec_deg},0)"` pattern in `_objects_near_python()`.
+
+```sql
+-- Before (fragile text cast):
+SELECT * FROM sky_cache
+ORDER BY eq <-> '(4.292,20.600,0.000)'::equatorial
+LIMIT 10;
+
+-- After (typed bind parameters):
+SELECT * FROM sky_cache
+ORDER BY eq <-> make_equatorial($1, $2, 0.0)
+LIMIT 10;
+```
+
+`IMMUTABLE STRICT PARALLEL SAFE`. Same validation as `equatorial_in()`: RA in `[0, 24)`, Dec in `[-90, 90]`, rejects NaN/Inf.
+
+## Feature 2: Rise/Set Predictions (8 functions)
+
+| Function | Threshold | Notes |
+|----------|-----------|-------|
+| `planet_next_rise(body_id, obs, t)` | 0.0 deg | body_id 1-8, rejects 0 (Sun) and 3 (Earth) |
+| `planet_next_set(body_id, obs, t)` | 0.0 deg | |
+| `sun_next_rise(obs, t)` | 0.0 deg | |
+| `sun_next_set(obs, t)` | 0.0 deg | |
+| `moon_next_rise(obs, t)` | 0.0 deg | |
+| `moon_next_set(obs, t)` | 0.0 deg | |
+| `sun_next_rise_refracted(obs, t)` | -0.833 deg | Refraction + semidiameter |
+| `sun_next_set_refracted(obs, t)` | -0.833 deg | |
+
+All `STABLE STRICT PARALLEL SAFE`. Returns `NULL` if no crossing within 7 days (circumpolar / polar night). Bisection to 0.1s precision, adapted from the satellite pass prediction algorithm.
+
+Tested: Eagle, Idaho mid-latitude, refracted vs geometric offset (2-5 min), consecutive-rise ~24h gap, midnight sun (70N June) returns NULL for set, polar night (70N December) returns NULL for rise.
+
+**Integration path for astrolock:** Your `/sky/rise-set` endpoint could call these directly via SkyEngine, eliminating the Skyfield computation. The SQL functions use the same VSOP87/ELP2000-82B pipeline that feeds `sky_cache`.
+
+## Feature 3: Nutation (IAU 2000B)
+
+The existing `get_nutation_angles_iau2000b()` in `precession.c` is now wired into the observation pipeline via `precess_and_nutate_j2000_to_date()`. Four dominant lunisolar terms, ~17.2 arcsec amplitude in longitude, ~9.2 arcsec in obliquity.
+
+**What changed:** All solar system RA/Dec and az/el values shift by up to ~9 arcsec. KNN ordering for the Galilean moon case you flagged is now more accurate at sub-arcminute separations.
+
+**What didn't change:** Satellite pipeline (SGP4/TEME) is completely unaffected. All 8 satellite-only test suites are bit-identical to v0.12.0.
+
+## Migration
+
+```sql
+ALTER EXTENSION pg_orrery UPDATE TO '0.13.0';
+```
+
+No reindex needed. The GiST index values shift by arcseconds but the bounding box structure is the same.
+
+---
+
+**Next steps for recipient:**
+- [ ] astrolock-web: Replace `f"({target.ra_hours},{target.dec_deg},0)"` with `make_equatorial($1, $2, 0.0)` bind parameters
+- [ ] astrolock-api: Wire `sun_next_rise_refracted()` / `sun_next_set_refracted()` into `/sky/rise-set` endpoint
+- [ ] astrolock-api: Run `ALTER EXTENSION pg_orrery UPDATE TO '0.13.0'` on production after pg_orrery v0.13.0 is tagged

+| Re | v0.13.0 integration plan — all three features |
+
+---
+
+## Acknowledged
+
+All three features landed exactly as requested. Reviewing the integration touchpoints:
+
+## 1. `make_equatorial()` — Replace string formatting
+
+**Current code** (`sky_engine.py:1131`):
+```python
+target_eq = f"({target.ra_hours},{target.dec_deg},0)"
+```
+
+**SQL template** (`_OBJECTS_NEAR_SQL`):
+```sql
+eq <-> :target_eq
+```
+
+**After:** Replace the text cast with `make_equatorial()` in the SQL template and pass RA/Dec as separate bind params:
+
+```sql
+eq <-> make_equatorial(:ra, :dec, 0.0)
+```
+
+```python
+# sky_engine.py:1131-1139
+result = await db.execute(
+    text(self._OBJECTS_NEAR_SQL),
+    {
+        "ra": target.ra_hours,
+        "dec": target.dec_deg,
+        "ref_type": target_type,
+        "ref_id": target_id,
+        "radius": radius_deg,
+    },
+)
+```
+
+Eliminates the f-string injection surface. Single file change, single SQL template update.
+
+## 2. Rise/Set — Replace Skyfield with SQL functions
+
+**Current code** (`sky_engine.py:1196-1231`):
+- Imports `skyfield.almanac`, creates an `observer_topo`, calls `risings_and_settings` + `find_discrete`
+- Only works for planets, sun, moon
+- Synchronous (blocks the event loop when called from async endpoint)
+
+**After:** Replace with async SQL queries calling `sun_next_rise_refracted()`, `planet_next_rise()`, etc. via the existing `db` session.
+
+Key mapping:
+```
+target_type="planet", target="mars" → planet_next_rise(4, obs, t), planet_next_set(4, obs, t)
+target="sun" → sun_next_rise_refracted(obs, t), sun_next_set_refracted(obs, t)
+target="moon" → moon_next_rise(obs, t), moon_next_set(obs, t)
+```
+
+Requires mapping planet names to pg_orrery body_ids (Mercury=1...Neptune=8, skip Earth=3).
+
+Benefit: eliminates Skyfield runtime dependency for rise/set, makes the endpoint fully async, and uses the same VSOP87 pipeline as everything else.
+
+## 3. Nutation — No code change needed
+
+The nutation correction is internal to pg_orrery's computation pipeline. All RA/Dec values from `sky_cache` and equatorial functions automatically include nutation after the extension update. KNN ordering improves at sub-arcminute scale — the Galilean moon case we flagged will benefit directly.
+
+## Migration sequence
+
+1. Tag pg_orrery v0.13.0 on `phase/spgist-orbital-trie`
+2. Deploy to production: `ALTER EXTENSION pg_orrery UPDATE TO '0.13.0'`
+3. Verify: `SELECT make_equatorial(18.616, 38.78, 0.0);` returns a valid equatorial
+4. Apply `make_equatorial()` change to `_objects_near_knn()`
+5. Apply rise/set SQL replacement to `rise_set_times()`
+6. Run astrolock test suite (currently 54/54)
+7. Deploy astrolock-api
+
+## Questions
+
+- Is v0.13.0 tagged yet, or still on `phase/spgist-orbital-trie` only?
+- The `_refracted` variants use -0.833 deg threshold. Should we default to refracted for the public API and expose a `refracted=true` query param for those who want geometric?
+

Ryan Malloy	a349f5505a	Add v0.13.0: nutation, make_equatorial constructor, rise/set predictions 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.	2026-02-25 13:53:22 -07:00
