VidPhysOracle appearance-transfer videos

Layout: <material>/<scenario>/<raw_sample_id>/<variant>.mp4. Materials use rigid, soft, and liquid (original fluid renamed). Example: rigid/dominoes/dominoes_0000/appearance_00.mp4. Named flag variants retain their original names, e.g. black_disc.mp4.

• manifest.json: one entry per Raw sample; transfer paths are relative to this folder. This is a transfer inventory, not a complete generation manifest: Raw reference paths and generation prompts must be supplied when combining with Raw data.
• file_manifest.json: original-to-new path mapping, byte sizes, and SHA-256 for every video.
• verification.json: counts and copy verification results.

All 6,272 official videos are independent copies, not symlinks or hard links. Source files remain unchanged in the sibling transfer_6272 folder. Selection duplicates, download tools/logs, and other source auxiliary files remain there and are not part of this release tree.

When downloaded into data/transfer/, a combined dataset manifest rooted at data/ must prefix these video paths with transfer/ and associate each sample with its Raw reference directory. No Raw annotations are included here.
