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.

<h1>WAI <em>spatial audio</em> — object-based sink</h1>
|
|
<p class="sub">
|
|
A <code>wai.audio.scene</code> arrived: sound <b>objects</b> (each a content-addressed source + a
|
|
position trajectory), not a baked stereo mix. This tab renders them to a stereo mix with the same
|
|
deterministic Rust mixer that generated the conformance corpus, then checks the BLAKE3 of its PCM
|
|
against the corpus's expected <code>mixdown_hash</code> — <b>mixdown-equivalence</b>, the audio
|
|
counterpart of replay-equivalence. The radar shows each object's position; press play to hear it pan.

<b>What you are hearing:</b> not a recording — a render. The wire carried objects + trajectories;
|
|
your device made the mix. The mixdown is bit-exact (`wai.det.fixed64` floor, sqrt-only constant-power
|
|
pan), so the hash above equals the one in <code>audio-conformance/expected_hashes.json</code> — the
|
|
same number on any machine. A real sink can also render to its own layout (5.1, binaural/HRTF); the
|
|
bit-exact stereo floor is the conformance contract.
