feat(fullstack): v1.2.1 geo-zoning, per-zone seismograph and GNSS readiness - #367
Merged
Conversation
- geohash Redis zone index (geo.py) with PostGIS source of truth
- Redis Streams ingestion substrate (ingest.py) + TimescaleDB migration (timescale.py)
- GNSS-ready data model: Sensor.last_fix_at, Reading.lat/lon
- per-area cooldown fragmentation in worker
- DELETE /zones/{id}/readings and GET /zones/{id}/alerts endpoints
- zone/geo/timescale integration and unit tests
- live per-zone seismograph feed (useZoneReadings) with horizontal zone strip - sliding window chart anchored to wall clock + linear MAG scale - GPS zone detection (expo-location -> /zones/locate) - MIC/RESEARCH theme toggle + civil-defense siren on critical alerts - Settings Explore section + v1.2.1 footer
- optional GnssModule with UART fix + NVS last-known location (GNSS_ENABLED) - provisioning sends real fix when available, else last-known / omits - updated config example and platformio deps
- run test_geo_integration.py against real PostGIS + Redis - run test_timescale_integration.py against real hypertable - run test_zone_readings.py against fresh PostGIS (new per-zone job)
- CITATION.cff to v1.2.1, date 2026-08-14 - CHANGELOG v1.2.1 (geo-zoning, zone endpoints, live chart overhaul) - README roadmap: v1.2.1 current - backend README: locate + zone readings/alerts endpoints - ROADMAP: v2.0.0 KiCad/PCB design done, fabrication pending
- use cryptographically strong SystemRandom in zone simulator (S2245) - wrap JSX text separator in braces to avoid comment parsing (S6438)
- only swallow the expected BUSYGROUP redis error in ingest group creation - declare explicit non-root USER in the timescale postgres image (S6471)
