FA-53274 / Raster memory layout / Member archive

Volume Transfer Skip Footprint: Destination volume inherits source footprint or omits slice pitch · case 04

The returned physical layout descriptor disagrees with the declared buffer mapping at destination_rows.

Case contract

A 3D upload buffer has independently specified row length, image height, and byte pixel size. A valid subvolume starts after skipped images, rows, and pixels. Destination uses independent row and slice pitches; return all per-row transfer origins. Return the named intermediate layout descriptor and final address fields; all quantities are integer byte offsets unless explicitly stated.

Why this case matters

Offline raster resource, upload, readback, and storage-layout regression model.
