Each *-conformance/README.md now has a line that begins **Provenance.**: the generator that writes the corpus and its input, and for an input not generated here its source and licence. OER/2's corpus is settled and left as it is. byte-exact-conformance and quantum-ops-conformance get a README. wai-rs/tests/vectors/README.md gives a row per vector directory. Where the staged-delivery, staged-measurement and telemetry READMEs called their content "synthetic", that sentence is now their provenance line. Two vectors are recorded as not generated, from the provenance audit: int_video's video_real (a pan over a third-party picture) and neural-conformance's photo (a third-party picture, with a decoder trained on unrecorded images). Their lines say so and that they are to be replaced; the photo bullet no longer names the picture's source product. tests/corpus_provenance.rs requires the line in every corpus and a row for every vector directory; CI runs it with the carriage tests. CONTRIBUTING states the rule: corpus content is generated here, or recorded with a licence that permits redistribution, and a word like "synthetic" is not a provenance line.

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.
Provenance. Generated here: wai_splat4d_vectors gen writes every vector from clouds and tracks authored in code. No capture.
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.
