- Unify haversine_km / deg_to_rad: Geo is the canonical home (atan2
form for antipodal stability); Radio, common_volume, rain_scatter,
ionosphere, terrain/srtm, terrain/elevation_client now delegate.
- Drop safe_min/safe_max wrappers in favor of Enum.min/max defaults.
- Move parse_float / parse_int to MicrowavepropWeb.LiveHelpers; eme,
path, and rover LiveViews import from there.
- Extract MicrowavepropWeb.LocationResolver from the eme/path
resolve_source / resolve_location duplicate. Standardize the kind
key and "Invalid grid square" error message.
- Convert Scorer cond chains (humidity, td_depression, sky, wind,
rain, pwat, pressure) to multi-clause guarded defs, matching the
existing classify_time_period style.
- extract_profile_fields uses a named map accumulator instead of a
6-tuple; build_path_conditions guards on %{temps: []} / %{dewpoints: []}.
- Collapse scores_file clamp/3 to max |> min.
- humidity_effect_label lives in BandConfig; map_live and path_live
both use it.
