Clip	Episode	Pinned source shard	Source interval
case-01	278	videos/observation.image/chunk-000/file-002.mp4	2839.4–2875.1 s
case-02	140	videos/observation.image/chunk-000/file-001.mp4	1057.5–1103.0 s
case-03	340	videos/observation.image/chunk-000/file-003.mp4	528.4–574.7 s

media/case-01.mp4, case-02.mp4 and case-03.mp4: episode excerpts, AV1 packet remux with episode-local timestamps, no video re-encoding. Modification and attribution notices are embedded in each MP4's comment metadata. This package adds those notices and fast-start container layout; decoded frames and timestamps are preserved.
telemetry/case-01.json, case-02.json and case-03.json: selected episode timestamps and seven native state values extracted from the source Parquet into JSON. Values and frame order are preserved; other native columns are omitted from this view. Each file carries an explicit _provenance modification notice and exact source URL/checksum.
manifest.json: Coppertop's selected-episode metadata, computed heuristic scores and proposed review intervals. Its _provenance records the source mapping, modification notices and scorer revision. No human review or success/failure labels were created.

The exact conversion source is pinned above. Mapping back to original Stanford camera files or Zarr was not independently reconstructed. Whole upstream video-shard hashes are upstream declarations; acquired source ranges and derived clips were locally checked. Source physical units, coordinate frames and rotation conventions remain unspecified.

Viewer assets

The HTML, JavaScript, CSS, viewer copy and annotations were created for Coppertop. No third-party frontend library, downloaded font or external logo image is bundled. Dataset license declarations above apply to the source-derived content, not a blanket license for the viewer code. Source cards and license texts are preserved unchanged.
