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.

# Spatial-Audio Conformance Corpus
|
||
|
||
Vectors for the spatial-audio extension's **mixdown-equivalence**
|
||
criterion: given the same `wai.audio.scene` and the same declared output
|
||
layout, a conforming sink MUST produce the identical canonical PCM,
|
||
hence the identical BLAKE3 — on every machine, no tolerance parameter.
|
||
The audio counterpart of replay-equivalence.
|
||
|
||
All vectors mix to the mandatory `stereo` floor under the
|
||
`wai.det.fixed64` numeric profile, `wai.audio.pan.sqrt_constpower` pan,
|
||
`wai.audio.dist.inverse_clamped` distance. Sources are deterministic
|
||
synthetic tones (no clock, no entropy); in a real sink they'd be decoded
|
||
`wai.audio.*` assets — the corpus provides the decoded mono PCM so each
|
||
vector isolates the one new thing, the deterministic mixdown.
|
||
|
||
## Layout
|
||
|
||
- `vectors/<name>.wscn` — the scene container (contract + object table +
|
||
asset table).
|
||
- `vectors/<name>.sources.bin` — the decoded mono sources:
|
||
`n u32 | n × (hash[32], len u32, i16le[len])`, sources in hash order.
|
||
- `expected_hashes.json` — per scene: `scene_hash`, `layout`, and the
|
||
expected `mixdown_hash`.
|
||
|
||
Vectors:
|
||
- `stereo_pair` — two static sources, hard-left + hard-right.
|
||
- `distance` — one source placed near vs. far (inverse-clamped atten).
|
||
- `moving` — a source whose keyframed trajectory sweeps left→right.
|
||
|
||
## Running
|
||
|
||
```
|
||
cd ../wai-rs
|
||
cargo run --features audio_scene --bin wai_audio_vectors -- verify ../audio-conformance
|
||
cargo run --features audio_scene --bin wai_audio_vectors -- gen ../audio-conformance # regenerate
|
||
```
|
||
|
||
Pass = hash equality. A failed vector is a conformance failure of the
|
||
file or the sink — report it failed, never approximately right.
