Matt Johnson 35de09ea93 test: add hot-reload integration tests for cadence changes 
Add tests that exercise the ACTUAL running loop with cancel_event
signaling, not just AdapterState math in isolation.

Test cases:
- Test 1: Cadence decrease (60->30) wakes loop immediately
- Test 2: Cadence increase (10->20) extends wait correctly
- Test 3: Enable/disable/enable with gap > cadence polls immediately
- Test 4: Enable/disable/enable with gap < cadence waits

These tests verify the cancel_event mechanism properly interrupts
the sleeping loop when config changes occur via _on_config_change.

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
