open-standards/wai/avatar-conformance/README.md
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.

# Avatars Conformance Corpus
Vectors for the avatars extension (`wai.avatar.pose`). The criterion is
**pose-equivalence**, a special case of replay-equivalence: given the
same world container and the same signed animation op set, a conforming
sink MUST compute the identical BLAKE3 **state hash** at every
checkpoint — on every machine, no tolerance parameter. The state is the
set of per-bone **local transforms** (parent + translation + rotation
quaternion + scale, all `wai.det.fixed64`); the forward-kinematics
composition into world space and the skinning of a `wai.mesh.glb` are
the sink's presentation, never in the hash.
**Provenance.** Generated here: `wai_avatar_vectors gen` writes every vector from rigs and motion authored in code. No capture.
The container is the worlds `WWLD`; the sim is `wai.world.sim.skeletal0`
(the identity step — a pose changes only when a signed op sets a joint).
Mutations: `CREATE` / `DELETE` / `SET_ROTATION` / `SET_TRANSLATION` /
`SET_SCALE`, all LWW. The floor is trig-free: rotations are carried as
quaternions; axis-angle authoring happens off-line in the generator.
## Layout
- `vectors/<name>.wwld` — a sealed `wai.world.replay` avatar; the
manifest carries its per-tick checkpoint hashes.
- `vectors/<name>.ops` — a raw animation op log delivered against
`scene.wwld` in an adversarial arrival order; the manifest carries the
one `final_hash` every conformant sink must reach.
- `expected_hashes.json` — per vector: `type`, and the expected hashes.
Vectors:
- `arm_wave` — a 3-bone arm (shoulder → elbow → wrist) waving: the
shoulder and elbow rotate about z over four frames.
- `humanoid` — a 5-bone humanoid stub (pelvis → spine → head; spine →
l_arm, r_arm) struck into a pose: the right arm raises and the head
turns.
- `arm_wave_shuffled_{1,2,3}` — the arm-wave op stream in three seeded
shuffles; all converge to the sealed final pose hash.
## Running
```
cd ../wai-rs
cargo run --features world --bin wai_avatar_vectors -- verify ../avatar-conformance
cargo run --features world --bin wai_avatar_vectors -- gen ../avatar-conformance # regenerate
```
Pass = checkpoint/final hash equality.
