 The `full` split has one row per representation sample (600 rows). The other five splits select rows from that same index by group; they are **not additional samples**. Each row includes the episode, camera, representation, prompt text, paths to directly downloadable files, source paths, SHA-256 hashes, and visual-revision indicators.
 
+The `preview_image` column uses the Hugging Face `Image` feature. It contains **one representative image per episode** (170 total), attached to the selected `mixed` sample; the other representation rows have no image in that column. For 60 episodes the image is the recorded RGB first frame (`preview_kind=rgb-first-frame`). For 110 episodes without one, it is the first frame of the selected proxy input video (`preview_kind=proxy-video-first-frame`). A proxy preview is **not** an RGB conditioning first frame. The image bytes are embedded in Parquet for the Dataset Viewer and the file path is available in `preview_file`. Private Viewer availability depends on Hugging Face account or organization support; the files can still be downloaded directly.

+`release.json` records the source snapshot, archive checksum, and visual revisions. `snapshot-files.jsonl.gz` lists the archived paths, file hashes, and symlink targets. `organized-files.jsonl.gz` separately verifies the directly browsable copies, records their source paths, and links derived preview frames to their source videos. `SHA256SUMS` verifies the top-level release files and split indexes.
 
 The source snapshot stores Gunfight records in `episodes/gunfight`, while its existing catalogs call the group `neon`. The archive includes the compatibility symlink `episodes/neon -> gunfight`, so the catalog paths resolve. The recorded content is unchanged. The Parquet field `video_matches_source` is false for **76** samples whose proxy video has a documented visual revision relative to its source video; this is a provenance distinction, not a missing file. See the archive's `provenance/` records and `promptBinding` in `samples.jsonl` before comparing historical model outputs.
