Matt Johnson 7fdf47f2f0 feat(tomtom_incidents): per-bbox cadence (v0.9.5.1) 
Lets each incident bbox poll at its own interval so busy metros refresh more
often than quiet corridors. Backward-compatible, code-only patch.

- Optional BBox.cadence_s (int | None = None) -> per-bbox poll interval; None
  falls back to the adapter's default_cadence_s. Existing settings without the
  field keep their current behavior.
- In-memory _last_polled {bbox_name: datetime}, per process. _bbox_due() gates
  fetches; poll() fetches only due bboxes. First poll after (re)start fetches all
  (one-shot catch-up; storage dedup on <state>:tomtom:<id> collapses overlap).
- _last_polled is recorded ONLY after a successful fetch -- a failed bbox stays
  due and retries next cycle (regression-guarded).
- Supervisor wakes the adapter at the adapter-level cadence; set that to the GCD
  of the per-bbox cadences for exact intervals (extra wakeups cost zero API calls).

central-supervisor restart only. No gui/archive restart, no migration, no new dep.

Full suite: 815 passed, 1 skipped (central and unprivileged zvx, 3x each).

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.
