Transaction Science 46c5688b86 wai: the WAI open standard — full cargo-class surface + provenance 
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.

State-Feeds Conformance Corpus

Vectors for the state-feeds extension (wai.feed.state). The criterion is replay-equivalence, reused wholesale from interactive worlds: given the same world container and the same signed op set, a conforming sink MUST compute the identical BLAKE3 state hash at every checkpoint — on every machine, no tolerance parameter. A state-feed is a non-physics world whose sim (wai.world.sim.feed0) is the identity step; convergence comes entirely from applying typed-field updates in the canonical total order.

The container is the worlds WWLD; the node is a record of self-describing typed cells (Int i64, Fixed Q32.32, Text UTF-8). Mutations: CREATE / DELETE / SET_CELL (LWW) and ADD_INT / ADD_FIXED (SUM — commutative accumulation).

Layout

  • vectors/<name>.wwld — a sealed wai.world.replay feed; the manifest carries its per-tick checkpoint hashes.
  • vectors/<name>.ops — a raw 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:

  • scoreboard — two team records; scores rise by SUM increments (order-independent within a tick) with one LWW correction.
  • telemetry — a sensor record; temperature set absolutely (LWW), packet count accumulated (SUM), including a negative ADD_FIXED.
  • market_ticks — an instrument record; last price is LWW, volume is SUM.
  • scoreboard_shuffled_{1,2,3} — the scoreboard op stream in three seeded shuffles; all converge to the sealed final hash.

Running

cd ../wai-rs
cargo run --features world --bin wai_feed_vectors -- verify ../feed-conformance
cargo run --features world --bin wai_feed_vectors -- gen    ../feed-conformance   # regenerate

Pass = checkpoint/final hash equality.
