FA-52016 / Raster memory layout / Open access
Compressed Block Payload: Compressed texel coordinates are not converted to block coordinates · case 01
The returned physical layout descriptor disagrees with the declared buffer mapping at block_start.
ROOT CAUSE
Compressed texel coordinates are not converted to block coordinates The faulty expression is p["base"]+(p["y"]//3)*row_pitch+p["x"]*block_size.
VERIFIED REPAIR
Apply the stipulated layout rule at block_start: p["base"]+(p["y"]//3)*row_pitch+(p["x"]//4)*block_size.
Unsuccessful approach: The attempted repair uses p["base"]+p["y"]*row_pitch+(p["x"]//4)*block_size and still violates the layout contract.
Case contract
A stipulated 4x3 block format stores 5 endpoint bytes followed by twelve one-byte texel selectors. Block rows are padded to a multiple of three blocks; selector lookup never decodes colors. 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.

Verification & scope
Stipulated deterministic toy buffer layout; not a graphics API, codec, GPU vendor tiling specification, or hardware-conformance claim. Inputs satisfy the dimensions and bounds stated by the model. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
