| # Validation Report |
|
|
| ## Scope |
|
|
| Release candidate metadata was compared with: |
|
|
| - source commit `339e6149de130cbe2d001f7a0e5247872bc788ec` |
| - all 335 rows in the pinned source `metadata.csv` |
| - 3 previously unindexed direct Standard files |
| - all 465 rows in the corresponding base Dataset Viewer snapshot |
| - the complete PR-side repository inventory |
| - the revised 129-row active pre-standard index |
|
|
| The full archive was not downloaded. For the three added Standard records, the |
| local inbox files were read without modification to extract container and |
| stream metadata, and their complete SHA-256 hashes were verified against the |
| current Hub LFS identities. The excluded local holding was not uploaded, copied |
| into the release candidate, or represented by an active metadata row. |
|
|
| ## Result |
|
|
| **PASS — zero structural validation errors** |
|
|
| | Check | Result | |
| | --- | ---: | |
| | Canonical metadata rows | 338 | |
| | Metadata columns | 29 | |
| | Unique `record_id` values | 338 | |
| | Unique canonical paths | 338 | |
| | Unique nonblank content hashes | 338 | |
| | Canonical repository paths matched | 338/338 | |
| | Direct standard MP4 files | 338 | |
| | Standard files pending metadata ingestion | 0 | |
| | Published pre-standard MP4 files | 129 | |
| | Active pre-standard metadata rows | 129 | |
| | Missing active metadata targets | 0 | |
| | Pipe separators remaining in canonical tool/media fields | 0 | |
| | Stored-orientation conflicts | 0 | |
| | Duplicate canonical content hashes | 0 | |
|
|
| ## Audited statistics |
|
|
| - Canonical playback duration: 40.46 hours |
| - Median canonical playback duration: 340.955 seconds |
| - Canonical indexed size: 1.647 TB decimal |
| - Stored orientation: 336 portrait, 2 landscape |
| - Audio streams: 334 present, 4 absent |
| - Unknown canonical finish times: 33 |
|
|
| ## Outstanding warnings |
|
|
| 1. All 129 active pre-standard rows lack duration and core technical metadata. |
| 2. Most canonical masters retain audio; rights and privacy review remains |
| necessary. |
| 3. Encoded frame rate is playback rate and cannot be used as original |
| drawing-time sampling. |
| 4. The 2012–2016 layer has no public video payload at this snapshot. |
| 5. No leakage-safe train/validation/test partition has been defined. |
|
|
| ## Reproduction |
|
|
| Generate the candidate canonical index: |
|
|
| ```bash |
| python tools/repair_metadata.py source_metadata.csv metadata.csv \ |
| --additions tools/metadata_additions_v0.2.csv |
| ``` |
|
|
| Validate the canonical index: |
|
|
| ```bash |
| python tools/validate_metadata.py metadata.csv |
| ``` |
|
|
| Use a Viewer snapshot only when it was built from the same metadata revision: |
|
|
| ```bash |
| python tools/validate_metadata.py metadata.csv --viewer-json viewer_rows.json |
| ``` |
|
|
| For a repository-inventory check, also provide the active pre-standard index |
| and a JSON list of repository paths: |
|
|
| ```bash |
| python tools/validate_metadata.py metadata.csv \ |
| --pre-standard-metadata Pre_Standard_Time_Lapses/metadata.csv \ |
| --repo-files-json repo_files.json |
| ``` |
|
|
| The available `viewer_rows.json` records the pinned base Viewer state. It is an |
| historical audit input, not part of the proposed upload, and is expected to |
| differ from the revised indexes until the Viewer rebuilds. |
|
|
| `repo_files.json` is an audit input captured from the pinned PR repository |
| inventory; it is not part of the proposed repository upload. |
