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'.
