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.

Fix all 12 dialyzer warnings
...
- Replace MapSet with plain list + `in` (features.ex, scorer_diff.ex)
- Remove undefined Beacon.t() type reference (range_estimate.ex)
- Remove dead else branch in find_region (inversion.ex)
- Handle Nx special values in to_float catch-all (recalibrator.ex)
- Remove unreachable catch-all clauses (hrrr_native_client.ex, ncei_metar_client.ex)
- Remove unnecessary nil guards on always-typed values (show.ex)
- Remove dead sky_note/wind_note non-nil clauses (show.ex)
- Remove dead if-guard on always-truthy derive result (hrrr_native_derive.ex)
- Add @spec to path_integrated_conditions (scorer.ex)

Phase 9.3, 9.4, and Phase 3 NEXRAD pipeline
...
Task 9.3 - Weight recalibration via gradient descent:
- Recalibrator module fits logistic regression weights using Nx
- Trains on QSO positives vs random baseline negatives
- Cross-validates by month, normalizes weights to sum to 1.0
- Mix task: mix recalibrate_scorer --sample 5000 --epochs 2000
Task 9.4 - Side-by-side scorer comparison:
- ScorerDiff.compare/3 re-scores grid with old vs new weights
- Reports mean diff, regressions, improvements, per-band breakdown
- Mix task: mix scorer_diff --new-weights '{...}'
Phase 3 - NEXRAD ingestion pipeline:
- NexradClient fetches IEM n0q composite PNGs, extracts per-point
box statistics (mean/max dBZ, texture variance)
- NexradObservation schema with unique (lat, lon, observed_at)
- NexradWorker on :nexrad queue for background processing
- nexrad_texture backtest feature in Features module
- mix nexrad_backfill --limit 200
All tasks added to AdminTaskWorker and Release for production use.
1116 tests, 0 failures.

Phase 8: 5-minute METAR ingestion pipeline
...
NCEI ASOS 5-minute data client (Weather.NceiMetarClient):
- fetch/3 pulls per-station monthly .dat files from NCEI C00418
- parse/1 decodes the fixed-width METAR format including precise
T-group temperatures (T02110094 → 21.1/9.4°C)
- metar_5min_observations table: schema-identical to
surface_observations, separate table to avoid mixing cadences
Weather.recent_surface_obs/3 prefers 5-min data when available,
falls back to the hourly surface_observations table.
Data URL: https://www.ncei.noaa.gov/data/automated-surface-observing-system-five-minute/access/YYYY/MM/asos-5min-KXXX-YYYYMM.dat
Available back to 1996.
