Central Bot f395425998 v0.9.21: FIRMS satellite pixel polygons via Geo.geometry 
FIRMS hotspots rendered as tiny dots on /events because the adapter shipped
a degenerate point-bbox (lon,lat,lon,lat) and no geometry. _build_geom_sql
collapsed that into a 5-vertex zero-area Polygon. Fix: construct a real
rectangular GeoJSON Polygon from (latitude, longitude, scan, track) per
record and ship it via Geo.geometry, mirroring the v0.9.3 pattern used by
tomtom_flow.

- _pixel_polygon() builds a CCW 4-corner ring with the closing vertex
  duplicated. Cross-track (longitude) extent scales by cos(lat). Latitude
  is pole-clamped to ±89° defensively.
- _row_to_event drops the degenerate bbox and sets geo.geometry; centroid
  stays alongside for consumers that read centroid only.
- poll() counts emitted records that fell back to centroid-only Geo
  (missing scan/track) and emits a single per-cycle warning if > 0,
  not per-record.
- Forward-only: same dedup keys, new payload shape for new records.
  Existing PostGIS rows retain their degenerate-polygon geometry until
  republished or aged out.
- Removes a pre-existing unused RegionConfig import in tests/test_firms.py.

Tests: 5 new pixel-polygon unit tests + 2 archive round-trip regression
guards mirroring test_archive_prefers_geo_geometry. Existing test_event_geo
updated to assert the new geometry shape. Full suite 930 passed, 1 skipped
under both central and zvx users.

README.md

Central

Central is the data hub spine for the infrastructure. Adapters normalize upstream sources into a canonical event shape, publish CloudEvents to NATS/JetStream, and archive to TimescaleDB for historical query. Single-LXC deployment.

Status

Phase 0 — scaffold. Not yet operational.

Architecture

  • Python 3.12 (uv-managed)
  • NATS + JetStream for live event bus
  • TimescaleDB + PostGIS for archive and geospatial query
  • One supervisor process managing adapter lifecycle
  • One archive consumer process persisting events to TimescaleDB
  • Both processes systemd-managed

Testing

See docs/test-database.md for test database setup.
