Commit the WAI standard source: a content + capability-dispatch standard
whose thesis is "carries whatever it can reconstruct, verifies whatever
it carries." Source only — large vendored/model assets and build output
are gitignored.
Reconstruct classes (each: spec + conformance corpus + in-tab browser
sink that re-derives the corpus hash, one wai.det.fixed64 fixed-point
floor, one *-equivalence apiece):
- interactive worlds (replay-equivalence) + 3 sim registrants,
multiplayer over a relay, session receipts, glTF + real SPZ assets
- spatial audio (mixdown-equivalence)
- haptics (sample-equivalence)
- state-feeds (replay-equivalence, non-physics sim)
- avatars / digital humans (pose-equivalence) + telepresence over the relay
- volumetric / 4D splats (frame-state-equivalence) + WebGPU EWA render,
real-SPZ-derived clip
Verify half (lever 4):
- asset provenance: a signed, energy-accounted lineage for opaque
captured content WAI does not reconstruct; tamper-evident, in-tab.
Cross-cutting: JWP receipt profiles per class; a native energy meter
(IOReport via macmon, no sudo) emitting receipts with REAL measured
joules; the learned-image/neural codec family and JPEG AI entropy port
from earlier work.

Volumetric / 4D Splat Conformance Corpus
Vectors for the volumetric extension (wai.splat.4d). The criterion is
frame-state-equivalence: given the same temporal-splat clip, a
conforming sink MUST reconstruct the identical Gaussian set at every
frame, hence the identical BLAKE3 — on every machine, no tolerance
parameter. The temporal counterpart of the static splat, with the
single cloud replaced by per-Gaussian keyframed tracks.
Each Gaussian carries a track of keyframes (frame, position, scale,
rotation quaternion, color, opacity, all wai.det.fixed64); the sink
interpolates linearly in the Fx floor at any frame. The frame hash is
BLAKE3(domain || frame || n_gaussians | per-Gaussian 14×i64). The
render of that set (EWA splatting, sort, blend) is the sink's
presentation, never in the hash.
Clips are self-contained, so each vector is a .w4ds container + its
per-frame expected hashes.
Layout
vectors/<name>.w4ds— theW4DScontainer (contract + Gaussian tracks).expected_hashes.json— per clip:n_gaussians,n_frames,clip_hash, andframes[]={frame, hash}for every frame.
Vectors:
orbit— two Gaussians swap x positions across 12 frames.pulse— one Gaussian scales up and fades out across 10 frames.morph— one Gaussian shifts color red → cyan across 8 frames.
Running
cd ../wai-rs
cargo run --features splat4d --bin wai_splat4d_vectors -- verify ../volumetric-conformance
cargo run --features splat4d --bin wai_splat4d_vectors -- gen ../volumetric-conformance # regenerate
Pass = clip-hash and every frame-hash equality.
