wai-pack conformance regen writes, and check recomputes:
- packs/video-base-01: policy, supplied AV1 floor, test key, and the whole package
the packer writes from the generated fixture, byte for byte, which the verifier
also verifies;
- mutations: stage indexes, objects and receipts, each with the reason it gets;
- receipts: the legacy version-1 receipt and an unmetered one as JSON.
