ordering. Its sorted episode-membership SHA-256 is
a7562985a12d41cfcc3f4e899bc2ca7658e0e28366699477e0196f67c04f4e25.
catalog.json lists only shards available in this repository revision and
records the original episode-space size. Consumers should pin an immutable
repository commit when streaming. The remaining shards can be appended later
at their existing paths, followed by publication of an expanded catalog.
The Lance stores contain JPEG frame rows and require a Lance-compatible reader. Users remain responsible for complying with the source dataset's terms and licenses.
