extensions/splat-exact.md registers wai.splat.exact: carriage in glTF as EXT_gaussian_splatting_compression_wai under KHR_gaussian_splatting, the attribute layout and its dequantization, the renderer wai-splat-render:i1, the commitment, the view statement, provenance, verification, reasons and the measured quality cost. The draft JSON Schema of the extension object is extensions/gltf/. The corpus gains cases the second implementation's self-falsification showed were missing: an unrequired extension, a buffer view past the envelope, a set whose bytes or pin alone disagree, a commitment naming another object or set, and statements naming another object or renderer or another pose's frame.
