Each *-conformance/README.md now has a line that begins **Provenance.**: the generator that writes the corpus and its input, and for an input not generated here its source and licence. OER/2's corpus is settled and left as it is. byte-exact-conformance and quantum-ops-conformance get a README. wai-rs/tests/vectors/README.md gives a row per vector directory. Where the staged-delivery, staged-measurement and telemetry READMEs called their content "synthetic", that sentence is now their provenance line. Two vectors are recorded as not generated, from the provenance audit: int_video's video_real (a pan over a third-party picture) and neural-conformance's photo (a third-party picture, with a decoder trained on unrecorded images). Their lines say so and that they are to be replaced; the photo bullet no longer names the picture's source product. tests/corpus_provenance.rs requires the line in every corpus and a row for every vector directory; CI runs it with the carriage tests. CONTRIBUTING states the rule: corpus content is generated here, or recorded with a licence that permits redistribution, and a word like "synthetic" is not a provenance line.

Score Conformance Corpus
Vectors for the score extension (wai.audio.score). The criterion is
mixdown-equivalence: given the same score, a conforming sink MUST
render the identical canonical i16 PCM via the deterministic reference
synth, hence the identical BLAKE3 — on every machine, no tolerance
parameter. The music counterpart of spatial audio's
mixdown-equivalence, with the recorded sound objects replaced by note
events.
Provenance. Generated here: wai_score_vectors gen writes every score from notes authored in code. No recording.
The reference synth is trig-free: a phase accumulator drives a
piecewise-linear oscillator (saw / square / triangle / pulse) shaped by
a linear ADSR envelope, all in the wai.det.fixed64 floor. Pitch is
carried as a per-sample phase increment authored off-line, so the floor
never evaluates an exponential. A sink with a soundfont or neural
instrument renders the same score richly — that is presentation, not
conformance.
Layout
vectors/<name>.wscr— theWSCRcontainer (contract + note events).expected_hashes.json— per score:notes,duration,score_hash(identity), andmixdown_hash(the conformance quantity).
Vectors:
scale— a C-major scale ascending (saw).chord— a C-major triad held together (triangle, polyphony).arp— a four-step arpeggio that changes timbre across the phrase.
Running
cd ../wai-rs
cargo run --features score --bin wai_score_vectors -- verify ../score-conformance
cargo run --features score --bin wai_score_vectors -- gen ../score-conformance # regenerate
Pass = mixdown-hash and score-hash equality.
