Time-Lapse Artifacts Viewer Test
Two public source rows for diagnosing the hosted Image/Xet permission-denied failure reported in huggingface/dataset-viewer#3476. This is a diagnostic fixture, not a new archival release or a representative sample.
The recording_physical_references/archive split has exactly two rows:
- Photograph:
tla-3f49a8917fe22676, worktlaw-b48060bdf38f5cb6. The Image contains the exact published JPEG bytes: 182,004 bytes, SHA-2560d5d812ffbe76b2e5e860a9fb54beb8087342ac7729550e2be08479bc66a18f5. Its original EXIF Orientation is 3. The embedded JPEG is not rotated or re-encoded; orientation must be checked in the hosted rendering. - Existing null-image control:
tla-f667e7cf1e5da54e, worktlaw-2d7ad769e1c86d52, retainingmissing_public_photoand a true null Image.
Both rows come from the published paired index at e102a3ef8843020230306f427549a81aaa489ffb
(SHA-256 e2f45a601c6b397e15a10363e02a9a1e1cdaaed490fd53dab89da5eeac435887). Their preserved source_hub_revision is 042469fe4bff3c7ffad36b47be25503bf73f0da6;
the image comes from the pinned original public JPEG.
Index row numbers, original row values, source hashes and attribution are in
provenance.json. The earlier image-source revision and the
later paired-index revision are distinct and both remain pinned.
All source scalar values, record IDs, work IDs, evidence and authority labels,
unknowns, and source URLs are preserved. Only the Image storage changes from a
remote reference to embedded bytes for the photograph. Its original hf://
reference is retained as text in Original image reference. file_name and
Recording URL are string fields; videos were not downloaded or embedded.
The image relationship remains proposed, with
deterministic_transitive_bridge evidence and
derived_from_owner_confirmed_edges authority. It is not direct owner
confirmation. The photograph does not establish the recording's endpoint.
The source image is a limited_resolution_full_drawing_reference.
The test asks whether hosted /rows can render an embedded-byte Image while
retaining the null control. Publication or pending processing alone is not a
successful runtime result. Viewer-generated preview assets may be re-encoded;
the exact original bytes remain in the Parquet file.

Image column delivery control (2026-10-20)
The image_column_control/archive config preserves every cell in the original
two-row fixture and adds an image column containing the exact same Image cells
as Physical reference photograph. Both image columns contain the same exact
182,004-byte JPEG in row 0 and a true null in row 1. No source JPEG was rotated,
re-encoded, renamed, or uploaded from private holdings. The original fixture and
its historical null control remain unchanged even though later production
photograph releases now cover that null row's work.
This within-row comparison tests whether generated-image delivery differs for
the spaced and simple Image column names. A difference narrows the failure to
column-dependent asset handling; it does not by itself prove an S3 key-encoding
or CDN implementation cause. /rows success, generated-image HTTP status and
full JPEG decoding must be checked separately. Pending processing is not success.
The control uses source table data/viewer-test.parquet at
d24ccd80b83eca4bd6744aaa3b54c8e4b16037c6. Its pinned provenance, source and control file hashes,
and byte-preservation assertions are in
image-column-control.provenance.json.
Observed delivery difference — October 20, 2026, 12:26 UTC
The within-row control completed processing at revision
c46b16af0260ef63f4c4bc97389967b821715419. Its paginated rows returned HTTP 200.
In row 0, Physical reference photograph returned HTTP 403 AccessDenied, while
image returned HTTP 200 and fully decoded as JPEG. Both generated URLs were
unexpired, both input Image cells contain the same exact 182,004 JPEG bytes,
and both columns retain a true null in row 1. The original fixture is unchanged.
This isolates column-dependent generated-asset handling. It does not establish a particular S3/CDN implementation cause or verify visible EXIF orientation. The timestamped sanitized observation contains status, revision and decoding evidence without signed image URLs.
