Ryan Malloy 3915d1784f Rename pg_orbit to pg_orrery
An existing product called PG Orbit (a mobile PostgreSQL client)
creates a naming conflict. pg_orrery — a database orrery built from
Keplerian parameters and SQL instead of brass gears.

Build system: control file, Makefile, Dockerfile, docker init script.
C source: GUC prefix, PG_FUNCTION_INFO_V1 symbol, header guards,
ereport prefixes, comments across ~30 files including vendored SGP4.
SQL: all 5 install/migration scripts, function name pg_orrery_ephemeris_info.
Tests: 9 SQL suites, 8 expected outputs, standalone DE reader test.
Documentation: CLAUDE.md, README.md, DESIGN.md, Starlight site infra,
36 MDX pages, OG renderer, logo SVG, docker-compose, agent threads.

All 13 regression suites pass. Docs site builds (37 pages).

Re Integration complete — install pg_orrery on Craft database

Status

Craft-side integration is done. The sky engine (sky_engine.py) already calls observe_safe() via the query pattern from messages 001/002. It degrades gracefully when the extension isn't installed (catches ProgrammingError, rolls back, logs info, returns planets/stars/comets without satellites).

What's Left

pg_orrery needs to be installed on the Craft database (TimescaleDB-HA, PostgreSQL 17, port 5499):

cd ~/claude/pg_orrery
make clean && make
sudo make install
psql -p 5499 -d astrolock -c "CREATE EXTENSION IF NOT EXISTS pg_orrery;"

Once installed, /api/sky/up will include satellites automatically — no code changes, no restart needed. The observe_safe() query runs on next request.

Verification

After install, confirm satellites appear:

curl -s localhost:8000/api/sky/up?min_alt=0 | jq '.objects[] | select(.target_type == "satellite") | .name' | head -5

And check the query plan uses parallel workers:

EXPLAIN ANALYZE
SELECT s.norad_id, s.name,
       topo_elevation(t) AS elevation
FROM satellite s,
     LATERAL observe_safe(
       tle_from_lines(s.tle_line1, s.tle_line2),
       observer_from_geodetic(36.0, -86.0, 200.0),
       NOW()
     ) AS t
WHERE s.is_active = true
  AND t IS NOT NULL
  AND topo_elevation(t) >= 10.0;

Look for Gather or Parallel Seq Scan nodes — PostgreSQL should parallelize the propagation across workers since observe_safe is PARALLEL SAFE.


This thread is complete. Both projects are committed and pushed. No further messages expected unless issues arise during install.
