 feat(gui): add streams view (1b-6) (#21) 
* feat(gui): add streams view (1b-6)

Add streams list and edit routes with live JetStream data:
- GET /streams: list all streams with live size/messages
- POST /streams/{name}: update max_age_s with validation

Features:
- Live data from JetStream (bytes, messages, timestamps)
- Graceful degradation when NATS unavailable
- Preset chip buttons (1d, 7d, 14d, 30d, 365d)
- Custom days input with Save button
- Current selection highlighted
- Managed by supervisor badge
- Audit logging with before/after max_age_s

Files:
- src/central/gui/audit.py: add STREAM_UPDATE constant
- src/central/gui/routes.py: add streams_list and streams_update handlers
- src/central/gui/templates/base.html: add Streams nav link
- src/central/gui/templates/streams_list.html: new template
- tests/test_streams.py: 9 tests covering all requirements

* fix(gui): use get_msg().time for stream timestamps, fix badge layout

- nats-py StreamState doesn't expose first_ts/last_ts
- Fetch timestamps via js.get_msg(stream, seq=N).time instead
- Handle edge cases: empty streams, single-message streams, get_msg failures
- Fix badge overlap using flex layout instead of float:right
- Change label from "Max bytes (config)" to "Max bytes (current)"

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.
