Final coverage round: 84.44% → 86.18% (target was 85%).
Two lib_ml/ tasks were stranded at 0% (1035 combined lines) because
the qsos → contacts table rename left stale refs in
PropagationAnalyze's SQL. Fixed:
- `FROM qsos q` → `FROM contacts q`
- `terrain_profiles tp ON tp.qso_id = q.id` → `tp.contact_id = q.id`
Adds test/mix/tasks/propagation_ml_tasks_test.exs with 4 tests:
- PropagationAnalyze end-to-end against empty DB (walks every section
header: correlation, binned factor, interaction, close).
- PropagationAnalyze with seeded contact + matching HRRR at both
endpoints yields a 1-row dataset (exercises derive_averages +
format_band + median + percentile helpers).
- PropagationAnalyze with a pre-2016-06-30 contact is excluded by the
WHERE clause.
- PropagationTrain on empty hrrr_profiles raises the expected Nx
"cannot build empty tensor" error after walking header + load path.
215 → 221 properties, 2812 → 2846 tests, 0 failures.
57,186 prod contacts stored pos1/pos2 with 'lng'; 1,133 used 'lon'.
Every Elixir caller carried a `pos["lon"] || pos["lng"]` fallback
— which just caused a SQL widget to silently miscount 98% of contacts
(count_narr_done used `pos1->>'lon'` directly, no fallback, so every
lng-keyed row returned NULL and failed the coverage check).
- Migration rewrites every pos1/pos2 JSONB in place, renaming 'lng' to
'lon' and dropping 'lng'.
- Removes all 20+ `|| pos["lng"]` fallbacks across lib/, workers,
scorer, weather, radio.ex, contact show view, and recalibrator.
- lib_ml/propagation_analyze.ex SQL now reads pos1->>'lon' directly
(was reading 'lng' only, which would have broken after migration).
- priv/repo/import_contacts.exs one-time seed script now emits 'lon'
with string keys, matching production shape.
- Test fixtures in 4 test files normalized to 'lon'.
- Two lng-characterization tests deleted — nonsensical post-normalize.
- Updated notebook + old import_weather script to match.
- JS hook contact_map_hook.ts TypeScript type narrowed to 'lon'.
- Nx, Axon, EXLA, Polaris deps restricted to only: [:dev, :test]
- model.ex and training mix tasks moved to lib_ml/ (compiled via
elixirc_paths in dev/test only)
- load_ml_model uses Code.ensure_loaded? + apply/3 to avoid
compile-time references to ML modules in production
- Verified: MIX_ENV=prod compiles clean with no ML warnings
