Matt Johnson 7eab5fc1b1 feat(wzdx): WZDx adapter + CENTRAL_TRAFFIC family bootstrap (v0.9.0)
Opens Phase 4 transportation aggregation (Design B, Central-direct). New
registry-driven wzdx adapter polls the FHWA WZDx Feed Registry, fetches each
eligible v4.x GeoJSON feed concurrently, and emits work_zone events into the new
CENTRAL_TRAFFIC stream. Production code; central-supervisor AND central-gui
restart (new adapter class + stream + ADAPTER_GROUPS). Ships disabled.

First adapter to use the category/subject split: category="work_zone.wzdx" (GUI
event_type "work_zone" via split_part) while the NATS subject is
central.traffic.work_zone.{state}. Subject state from the registry row, geocoder
state as fallback. Severity from vehicle_impact (all-lanes-closed=3,
some-lanes-closed=2, all-lanes-open=1, unknown/missing=1). Feed filter
geojson + active + needapikey=false + version 4.x (21 of 39 feeds). 600s cadence.
Dedup composite <data_source_id>:<feature_id> in the shared cursors.db; stateless
discovery (no conftest isolation entry). enrichment_locations uses the canonical
("latitude","longitude") paths.

Full suite: 739 passed, 1 skipped (central and unprivileged zvx, 3x each).

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.
