## 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.
