GET /events.json with cursor-based pagination and filtering: - Filter by adapter, category, since/until, region bbox - Cursor pagination via (time DESC, id DESC) ordering - Returns events with GeoJSON geometry parsed as objects - Validation returns 400 with clear error messages Migration 014 adds composite index for efficient pagination. Tests: 17 new tests covering filters, pagination, validation. Co-authored-by: Matt Johnson <mj@k7zvx.com> Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com> |

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.
