Independent Chroma Planes: V origin uses truncated U height or V pitch for U span · case 01

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

Verified by executionVariant 1 · 6 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

V origin uses truncated U height or V pitch for U span The faulty expression is u_origin+u_pitch*(p["h"]//2)+3.

VERIFIED REPAIR

Apply the stipulated layout rule at v_origin: u_origin+u_pitch*chroma_height+3.

Unsuccessful approach: The attempted repair uses u_origin+v_pitch*chroma_height+3 and still violates the layout contract.

Case contract

A 4:2:0 toy image has a byte luma plane plus independent U and V planes with distinct row guards. Chroma rounds odd dimensions up; plane headers are [1,2,3] bytes. Return physical sample locations for in-bounds luma coordinate. 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.
