# Haptics Conformance Corpus

Vectors for the haptics extension's **sample-equivalence** criterion:
given the same `wai.haptic.signal`, a conforming sink MUST reconstruct
the identical canonical `u8` buffer (per-channel interleaved
`[intensity, sharpness]`), hence the identical BLAKE3 — on every
machine, no tolerance parameter. The touch counterpart of
replay/mixdown-equivalence, with the tick replaced by the haptic sample.

**Provenance.** Generated here: `wai_haptic_vectors gen` writes every vector from envelopes authored in code. No recording.

All vectors reconstruct in the `wai.det.fixed64` floor (Fx linear
interpolation of the keyframed envelope → u8). Signals are
self-contained (no external sources), so each vector is just a `.whap`
file + its expected `signal_hash`.

## Layout

- `vectors/<name>.whap` — the `WHAP` container (contract + channel
  signals).
- `expected_hashes.json` — per signal: `channels` and `signal_hash`.

Vectors:
- `ramp` — intensity 0→1 over the duration.
- `thud` — full sharp hit, decaying.
- `dual_pulse` — two channels (dual-rumble): a strong pulse + a soft
  steady channel.

## Running

```
cd ../wai-rs
cargo run --features haptic --bin wai_haptic_vectors -- verify ../haptic-conformance
cargo run --features haptic --bin wai_haptic_vectors -- gen    ../haptic-conformance   # regenerate
```

Pass = hash equality.
