malice 0bf82b03a4 v0.12.1: n2yo_visualpasses adapter (server-side visible-pass alerts) 
Adds a new SourceAdapter that polls n2yo's visualpasses endpoint for
server-side visible-pass data: sun illumination + visual magnitude, both
data points that local SGP4 propagation from raw TLEs (v0.11.1
satpass_predict) cannot compute. Complement, not replacement.

Subject collision with satpass_predict on
central.sat.pass.us.<state>.<observer_slug> is intentional. Vendor
disambiguation lives in data.category (pass.n2yo_visualpasses vs
pass.satpass_predict); v0.10.8 category-discriminated Nats-Msg-Id keeps
the JetStream dedup windows distinct. CONSUMER-INTEGRATION.md flags
this explicitly for future consumers.

Severity bucketed by visual magnitude (LOWER mag = BRIGHTER): <=-3 -> 4
(very bright), -3..-1 -> 3 (naked-eye easy), -1..2 -> 2 (binoculars),
>2 -> 1 (telescope-grade).

Settings ship the curated default 6 observers (Filer primary +
Boise/Idaho Falls/Ogden/SLC/Provo) x 6 sats (ISS, NOAA-15/18/19, SO-50,
AO-91), sized for 6*6*24 = 864 transactions/day under n2yo's free
1000/day cap. data_class=event (alerts on /events, like satpass_predict).

API key plumbing via the established tomtom_flow pattern:
requires_api_key='n2yo', api_key_field='api_key_alias' settings field
binds the GUI api_key_select dropdown. _api_key cached via
ConfigStore.get_api_key, refreshed in apply_config; missing-key path
logs INFO and yields zero events (graceful, no exception). Live key
scrubbed from log strings via _redact.

No new stream (CENTRAL_SAT pre-existing; 'pass' token already in
STREAM_CATEGORY_DOMAINS from v0.11.1+v0.12.0). No new dep
(aiohttp already in venv). Migration 040 seeds config.adapters row
only; the n2yo API key gets added via GUI /api-keys page before
enabling.

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.
