Restore the gridded (model) representation of vector ranges

A vector range is published twice: the source polygons (native, PMTiles) and the same range gridded onto the 0.05 degree scoring grid (model, COG). v8 registers both; v9's native_asset lost every vector model row, so v9 shows no Interpolated view of any range although the gridded COGs were published (and are byte-identical to v8's). This adds, for every native PMTiles row that has no model row for the same mdl_key, one model COG row: same ds_key, ms_merge_key, bbox and source_layer, rescale_min/max 1-100, colormap spectral_r, and the URL (and content_hash) from model_urls. A PMTiles row with no URL in model_urls is an ERROR, never skipped: a release must not silently lose a representation twice.

Usage

native_asset_restore_model(native_asset, model_urls)

Arguments

native_asset

a v8-shaped native_asset (with content_hash once re-pointed to the store)

model_urls

data frame mdl_key, asset_url (+ optional content_hash): the gridded COG of each range

Value

native_asset with the missing model rows appended
