Ubuntu 40ea23e904 gui: fix consumers_info coroutine usage + list-returning test mock + None-guard counts 
- routes.py: change `async for ci in js.consumers_info(stream_name)` to
  `for ci in await js.consumers_info(stream_name)` — nats-py 2.14.0
  consumers_info() is a plain coroutine returning list[ConsumerInfo], not
  an async iterable; the old form threw TypeError silently (swallowed by
  except), causing every stream to show "unavailable" and zero consumers.
- test_consumers.py: replace async-generator mock with AsyncMock returning
  a list, matching the real API; also fix inline consumers_info_raising in
  the error test (remove dead yield); add explicit regression guard asserting
  consumer names appear in the template context.
- consumers_list.html: guard num_pending/num_ack_pending/num_redelivered/
  num_waiting with `… if … is not none else '—'` to prevent "None" in cells.

Central

Central is the data hub spine for the Echo6 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

Operational (v0.14.6) — deployed on utility CT 104 (central.echo6.mesh).

~22 adapters live across traffic, wildfire, weather, space-weather, hydrology, earthquakes, avalanche, disasters, and satellite. CloudEvents published to NATS/JetStream, archived to TimescaleDB/PostGIS. FastAPI + HTMX GUI/API on :8000.

Three systemd units on a single LXC:

  • central-supervisor — adapter lifecycle manager
  • central-archive — NATS consumer persisting events to TimescaleDB
  • central-gui — FastAPI + HTMX web interface / API (:8000)

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.
