  "about": "platform-decode §6.2: the decode-equivalence probe of base.wai, a grain-free wai.video.av1 stream. Each frame's sha256 is over its decoded samples as WebCodecs copyTo() writes them with no format, rect or layout option, I420: the luma plane, then Cb, then Cr, rows tightly packed (browser-sink §4.4); a frame a decoder outputs as NV12 is compared after its chroma plane is split. clip_sha256 is the SHA-256 of the frames' digests concatenated in output order (SPEC §7, Digests). Written from the reference decode (libdav1d) of the stream.",
