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).
