The sky's own schedule joins the orchestra. Unlike world_iss (which begs a web
API per position), world_sats fetches TLEs once from Celestrak — the stations
plus the named recon birds GAOFEN and COSMOS — caches them to
~/.cache/godverse/tles.txt (24 h freshness, atomic writes, stale-on-failure),
and propagates every craft locally with SGP4 at any rate, no per-fix HTTP.
For the venue city (--lat/--lon, retargeted by run.py) it computes each craft's
elevation above the horizon and emits:
/gs/sats/best_elev highest elevation among all tracked (-30..90 deg)
/gs/sats/overhead_count how many above 10 deg
/gs/sats/iss_lat/iss_lon ISS sweep (available even without world_iss)
/gs/sats/recon_elev best elevation among only the GAOFEN/COSMOS watchers
/gs/sats/pass.event impulse when any craft crosses rising through 30 deg
Wiring: config.json declares the six signals with norm ranges + labels, three
starter routes (best_elev -> pad.brightness, pass -> delay.feedback,
recon_elev -> lfo.rate) and adds sats.best_elev to the cosmos group; run.py adds
the worker to the WORLD profile and the lat/lon retarget set; requirements notes
the pure-python sgp4 dep. The worker is import-safe (sits out if sgp4 is absent)
and exits politely with no cache and no network. Grimoire + manual entry added.
Math ported from GODSIGH's verified satellites layer: TLE -> Satrec.twoline2rv
(handles no_kozai), SGP4 -> TEME km, GMST rotation -> WGS-84 geodetic, then an
ECEF up-vector for elevation. Verified end-to-end against live Celestrak data:
98 sats tracked, ISS position/altitude plausible, and all signals arrive over
the hub WebSocket correctly normalized with their routes active.

Everything — your hand, the room, a satellite, the markets, the sky — becomes an
OSC control signal fused through a modulation matrix. Includes:
- hub + normalize (One-Euro) + matrix (curves/gates/quantize) + transform (tweaks/groups)
- 20+ workers: sim sensors, 8 keyless world feeds, ephemeris/almanac/clock (computed),
time-warp replay (quakes/weather/db), and the dealgod market warehouse feed
- planetary orbital LFOs, SQLite recorder, city targeting
- live browser console: mute, group macros, drag-to-patch, inspector, Web MIDI
