live-conformance — the wai.live family

Conformance corpora of the live and interactive extensions, one directory per extension, and the independent verifier of each, beside it.

Provenance. Generated here: each directory's corpus is written by its row's generator (gen, in wai/wai-rs), from records authored in code and from fixed seeds, and each directory's README says how. c2pa-live/ cuts its media from the packaging corpus's AV1 floor; contribution/ and influence/ generate their pictures with wai.generate.spectral and the model file of that capability's conformance vector (influence/ also with a second model file written from it); takedown/ carries the registry of clocks the repository publishes, registry/takedown-clocks.json, as written there; and upscale/ reads two priors that tools/wai_int_sr_train.py trained on pictures it generates (upscale/README.md). tonemap/ renders generated HDR scenes to its stills with the reference's own encoder, and tone-maps the frames of the int_video clip of the integer video corpus. robustness/ generates its pictures with the dead-leaves generator of synthesis_mark and with wai.generate.spectral, and measures the synthesis corpus's measurement sets, whose samples it does not hold. splat/ carries the learned cloud of wai-rs/tests/vectors/int_splat/ beside scenes authored as attribute bytes. joule_moq_e2ee_vectors gen (in joule-code/joule-code-rs/crates/joule-moq-mls) writes e2ee/vectors.json from fixed seeds, and e2ee/ also holds the test vectors RFC 9605 and draft-ietf-moq-secure-objects-01 publish, as printed (e2ee/README.md), and aggregate/vdaf-22/ the Prio3 test vectors of draft-irtf-cfrg-vdaf-22, as published at the commit that draft names (aggregate/README.md). dred/ names the weights file of draft-ietf-mlcodec-opus-dred-07 by its SHA-256 and holds no copy: its generator and its verifier read the file the draft names, which dred/fetch.sh fetches and checks. One recorded record: metering/relay-record.wmh and its ledger, which the reference relay signed in its test.

Each verifier is written from its extension's text, shares no code with the reference (wai-rs, or for e2ee/, joule-moq and joule-moq-mls), and is run by .github/workflows/wai-conformance.yml beside the reference's own check:
