Everything here is evidence and state, not behavior: the shipped operating point is untouched at 512 px / 12 fps / noise_std=0.15. The carrier was downloaded and its sha256 matched the manifest, so its properties are now measured rather than assumed: 1920x1080 at 24 fps with an AAC audio track. Those three fields go into the two 2026-07-31 rows, which could not previously tell a reader what the downscale factor even was. The geometry prize is measured end to end for the first time. Against the untouched source, 1024 scores +3.46 dB over the shipped 512, while the entire noise_std axis is worth 1.92 dB. Two readings that the table alone hides are recorded with it: the temporal residual IMPROVES with resolution, because the shared noise field lives on the latent grid and is four times finer relative to the frame at 1920; and the frame-rate arm cannot be judged by these metrics at all, since they price its cost and not the smoothness it buys. Two findings that outrank the quality question. The certified row does not reproduce -- a rerun of the same configuration on a different device and dtype gives a different hash and different metrics, and the manifest records neither. And the pipeline copies audio byte for byte while stripping every metadata marker, so it can emit a file our own detector calls clean with an untouched Google-generated audio track inside it. The mechanism is proven on two carriers; whether that audio carries a mark the verifier reads is not, and only the oracle can say. The six prepared oracle submissions were never run: file upload to the verifier failed at the tool level. Their artifacts are gone with the scratch directory, which is the intended lifecycle for generated media, and the document says what rebuilding costs.
