Graham McIntire	5124cc09c1	Add IEM rate limiting, Req retry, and Oban retry for failed weather fetches ... IEM was returning 503s under 10 concurrent workers. Three fixes: - Req transient retry with exponential backoff on IEM requests - WeatherFetchWorker Oban job retries failed ASOS/RAOB fetches 2-3h later with random jitter to avoid thundering herd - Import script concurrency reduced 10→5, weather queue capped at 3	2026-03-29 13:24:52 -05:00
Graham McIntire	6f16395f44	Add QSO import, solar indices, Oban workers, LiveView UI, and parallel weather import ... - Radio context with QSO schema and CSV import script (58K contacts) - Solar index schema, GFZ client, and daily Oban cron worker - LiveView dashboard with QSO table and weather correlation views - Parallelize weather import script using Task.async_stream (10 concurrent workers) - Replace sequential rate_limit sleeps with concurrency-based backpressure - Atomic progress counter for interleave-safe reporting	2026-03-29 13:04:55 -05:00
Graham McIntire	6489f08138	Add weather data schema, context, sounding params, and IEM ingestion ... Store surface observations (ASOS) and upper-air soundings (RAOB) alongside QSOs for atmospheric propagation correlation. Three new tables: weather_stations, surface_observations, and soundings with JSONB profiles and pre-computed derived parameters (refractivity, gradients, duct detection, stability indices). Includes IEM API client for historical data import and import script seeded with 95 ASOS + 9 sounding stations from PropCast coverage area.	2026-03-28 15:57:19 -05:00
