Graham McIntire	9abbb83469	Fix credo warnings: struct specs, length/1, and test patterns ... - Replace %Struct{} with Struct.t() in all @spec annotations - Replace length(x) > 0 with x != [] in test assertions - Fix multi-line spec struct references in weather.ex	2026-04-12 10:26:53 -05:00
Graham McIntire	51e390959c	Add dialyzer specs and types across the codebase ... 277 @spec/@type annotations added to 58 files covering all public APIs: contexts (propagation, radio, weather, terrain, beacons, commercial), GRIB2 decoders, terrain analysis, duct detection, rain scatter, CSV/ADIF import, weather clients, and all Ecto schemas. Dialyzer passes with 0 errors.	2026-04-12 08:55:04 -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
