StormScope (GOES + MRMS), 8-bit for WebGPU: files for the Wallowa Weather app

Derived from NVIDIA StormScope (NVIDIA's model card): the MRMS model's three experts quantised to 8-bit integers per output row, the adaLN folded per sampler call, and packaged for WebGPU so the Wallowa Weather app can run it on a phone. These are not NVIDIA's original files.

Experimental. Not a National Weather Service warning. For warnings, follow the US National Weather Service (weather.gov).

Inputs: six 10-minute times of NOAA MRMS composite reflectivity, GOES-East ABI (8 bands, held at the newest image) and GLM lightning, on the HRRR 3 km Lambert grid; outputs: nine 10-minute frames (+10 to +90 minutes) of reflectivity and lightning.

File	What it is
manifest.json	every file, its sha256 and the sha256 of every 16 MiB chunk
stormscope_mrms_i8.json	the network: tensors and calls
stormscope_mrms_i8.bin	the 8-bit weights (348.5 MB)
ss_grid.bin	the grid tables (7.1 MB)
ss_grid.json	the grid, channels and normalisation

The app checks manifest.json against the sha256 it ships with, then every 16 MiB chunk of every file against the manifest. Only the app's own WebGPU engine reads these files (format pocketflux.pack/1).
