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.

wai-web demo — interactive-worlds browser sink
world.html is a conformant wai.world.replay sink running in a tab:
the WWLD payload (a tick-0 world + signed op log, ~1.3 KB for the truss
vector) is re-derived frame by frame in WebGPU by the same wai
crate native sinks run, compiled to wasm32 with the codec chain off
(--no-default-features --features world). At the sealed final tick
the sink recomputes the BLAKE3 state hash and compares it to the
publisher's Ed25519-signed seal — replay-equivalence, demonstrated:
the hash the browser computes is byte-identical to
world-conformance/expected_hashes.json.
Run
# from wai-web/: rebuild the wasm pkg after engine changes
wasm-pack build --target web --out-dir demo/pkg
# vectors come from the conformance corpus
cp ../world-conformance/vectors/{truss_fracture,ballistic_bounce,basic_kinematics}.wwld demo/vectors/
# serve (any static server; WASM needs http, not file://)
python3 -m http.server 8741
# → http://localhost:8741/demo/world.html
Needs a WebGPU browser (Chrome/Edge stable, Safari TP). No build steps beyond wasm-pack; no JS dependencies.
