Transaction Science 3fac029a71 wai: every corpus states the provenance of its content
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.

Linear-Film Conformance Corpus

Vectors for the linear-film extension (wai.film.linear). The criterion is film-equivalence: given the same film, a conforming sink MUST compute the identical per-frame identity — BLAKE3(world state hash at the frame's tick || the interpolated camera pose) — hence the identical per-frame hashes and the identical Merkle root over them, on every machine, no tolerance parameter.

Provenance. Generated here: wai_film_vectors gen writes every vector from shots authored in code. No footage.

A film composes two things already proven elsewhere: the embedded world's replay-equivalence (every sink agrees on the state hash at every tick — the world-conformance/ corpus) and the wai.det.fixed64 camera track (interpolated trig-free, like the splat/skeletal tracks). The render — the actual pixels — is the sink's presentation, not the verified quantity.

Layout

  • vectors/<name>.wflm — the WFLM container: a film contract, an embedded sealed wai.world.replay (WWLD), and a camera track.
  • expected_hashes.json — per film: frames, start_tick, ticks_per_frame, film_hash (identity), and frames_root (the Merkle root over the per-frame reconstruction hashes — the conformance quantity).

Vectors (each a complete film/reel in ~1 KB — the world plus the camera(s)):

  • dolly — one subject drifting; the camera dollies from behind to the side.
  • twoshot — two subjects moving apart; the camera holds, then pushes in (a two-leg move).
  • rise — a subject climbing; the camera cranes up and tilts (a quaternion lerp), starting at a non-zero tick.
  • character — the embedded world is a skeletal humanoid (the avatars sim) waving; film composes with avatar.
  • coverage (.wrel, a reel) — the character beat cut three ways: a wide establishing shot, a low push-in, then a cut back in time to a high angle on the same moment. kind: "reel" in the manifest, checked against reel_hash + frames_root.

Running

cd ../wai-rs
cargo run --features film --bin wai_film_vectors -- verify ../film-conformance
cargo run --features film --bin wai_film_vectors -- gen    ../film-conformance   # regenerate

Pass = film-hash + frames-root + frame-count equality, on every machine.
