One squashed history of three stacked PRs, onto main atb16816671: - #426 (wai/pack-efficiency): a title's whole AV1 ladder in one package over one integer base; several floor rungs (packaging §7.1), a re-pack from a parent (§11.5), a floor that is the ladder's own CMAF (§7.7), a floor-only profile (§7.8), a streaming pack (§11.4), and the independent verifier at scale (§9.4). - #438 (wai/cross-fabric): each pack and verify step on the fabric with the least measured energy (§11.6); the `fabrics` member of measurement claims (jwp-receipts §2.4.8, energy-measurement §6.3); the wai-pack-gpu crate; `wai-pack fabric`; `wai-pack floor-decode`. - #452 (wai/gpu-int-tier), its GPU-tier part only: claiming decode-equivalence on a GPU (determinism-tiers §5), the WGSL integer semantics suite, the rules check on naga's IR, and the kernels' shift masks and min(max()) clamps. Left out, by the review's split (EN-C takes it over): #452's platform decode in dispatch, its commits6ad92e2e8,8695bc75fandfed8694f4and its CHANGELOG entry: extensions/platform-decode.md, platform-decode-conformance/, wai::platform_decode, wai-web's platform_decode bundle and demo, and its two SPEC.md sentences. #438's research note is not carried as written: it is rewritten as wai/research/cross-fabric.md, with hardware named by architecture, PCI id and OS version, and every table marked as one run. floor_decode.rs and a wai_pack.rs comment name the platform's media engine and a full-length film the same way. wai/CHANGELOG.md is the union of both sides' entries, the stack's first.
