The Rust f01..f18 pipeline writes ProfilesFile cells, and the Rust hrrr_points worker writes hrrr_profiles rows, with profile entries keyed "pres_mb" / "hght_m" / "tmpc" / "dwpc" (string keys pre- atomization; atom keys post-ProfilesFile.read). Elixir's SoundingParams.derive and WeatherLayers.sort_profile filtered on "pres" / "hght" — so every derived field returned nil for any Rust-provided profile. Visible symptoms on /weather: N-gradient, Refractivity, T @ 850mb, Td @ 850mb, Lapse Rate, Inversion, Inv. Base all rendered no overlay. For per-contact analysis, min_refractivity_gradient from the Rust HRRR point worker's rows silently dropped. - SoundingParams.normalize_profile_entry/1: single-source normalizer accepting legacy, Rust-string, and Rust-atom shapes; returns the canonical "pres"/"hght"/"tmpc"/"dwpc"/"drct"/"sknt" shape. - SoundingParams.derive/1 and WeatherLayers.sort_profile/1 both run every entry through it before the rest of the existing logic. - Weather.build_grid_cache_row/4 now falls back to native_min_gradient when SoundingParams can't derive one (surface-only profiles). Also: - Default /weather overlay changed to Temperature (LiveView assign + JS fallback in the hook's dataset default) per user request.
