Ubuntu ef762ea8e4 gui: make consumers_delete guards DB-independent + add rendered-HTML tests 
Builds on the consumers_info coroutine fix:

- consumers_delete: acquire the DB pool only when actually writing the
  audit (after the CSRF / archive-guard / NATS-unavailable early exits)
  and use a local `get_js` import. Previously `pool = get_pool()` ran at
  the top, so the CSRF-reject, archive-refuse and NATS-down paths all
  needed an initialized DB pool, and the module-level get_js bound at
  import time ignored test patches of central.gui.nats.get_js. Mirrors
  the local-import pattern the streams routes already use.
- tests: add TestConsumersListHtmlRender — renders consumers_list.html
  through the real Jinja2 environment and asserts the consumer NAME
  reaches the HTML body, the central-owned label gates on `protected`,
  and None counts render an em dash rather than the literal "None".
  Stronger than the context-dict checks; the coroutine/None regressions
  cannot return. All 4 delete-route tests now pass (were failing on an
  uninitialized-pool RuntimeError).

README.md

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.
