The map size of the sample grid was recomputed from the expanded bounding box and the sample spacing stored in the project file. The expanded bounding box is an exact multiple of the sample spacing, but after the limited precision of the project file the division can land just above a whole number of cells, and the map size gets one extra cell. The cache files were then rejected, and the ensemble statistics recomputed. Store the map size in the project file, and use it directly when the sample grid is restored from the cache. Identify the input grids of the cache validity key by file path, size and modification time, so that the cache is also invalidated when a grid file is modified in place. Label and count the primary case and the ensemble cases, so that a primary case can not be mistaken for the first ensemble case.
