| # Release validation — SMedDV v5 |
|
|
| The commands below were run locally from the repository root. Source data in `data/synth/v5/` was read-only. No Hugging Face repo was created or contacted for this release; the live Hub viewer therefore was not tested. |
|
|
| ## Acceptance checks |
|
|
| | # | Check | Result | |
| |---:|---|---| |
| | 1 | Row accounting | **PASS** — 3,527,958 Parquet rows: 3,386,840 train and 141,118 validation. All source labels matched one Parquet row; 0 label/index mismatches. The 155 missing requested indices are all listed in `metadata/skips.jsonl`. | |
| | 2 | Split integrity | **PASS** — the validation indices equal `splits/validation_indices.json` (141,118 rows); indices are unique, no index crosses splits, and the 3,528,113-index request range is accounted for by rendered rows plus the 155 explicit skips. | |
| | 3 | Round-trip | **PASS** — 500 seeded random samples from Parquet shards decoded as WebP, 48 px high; logical and visual labels matched source UTF-8 bytes. 0 sample failures. | |
| | 4 | Label integrity | **PASS** — maximum length 64; all 503 non-space dictionary characters are present and no label character is outside the dictionary; minimum occurrences: 800 overall, 755 train, 24 validation. | |
| | 5 | Shard integrity and checksums | **PASS** — 19 Parquet shards, 12,092,403,362 bytes; per-shard SHA-256 values and the whole-package checksum verify with no mismatches. Original encoded image bytes accounted for: 11,872,335,840. See `data/build_manifest.json` and `checksums/`. | |
| | 6 | Leakage / prohibited files | **PASS** — no private absolute paths, credentials, `.env`, editor/cache files, or loose image files found in the package. | |
| | 7 | Hugging Face constraints | **PASS** — 97 package files, max 31 files in a folder, largest file 662,276,687 bytes. Parquet uses the HF `Image` struct metadata; README frontmatter parses and contains 53 language tags (MRZ is separate). | |
| | 8 | Reproducibility | **PASS** — source file hashes, source image content-tree hash, seed, commands, and the source code snapshot commit are recorded in `docs/reproducibility.json`, `docs/source-code.sha256`, and `data/build_manifest.json`. `CITATION.cff` parses as YAML and its required dataset fields were checked. | |
|
|
| ## Commands |
|
|
| Parquet build (single process, 2,048-row groups, approximately 650 MB of source image bytes per shard): |
|
|
| ```bash |
| PYTHONHASHSEED=0 .venv/bin/python release/v5_hf/tools/build_parquet.py \ |
| --source data/synth/v5 \ |
| --out release/v5_hf/data \ |
| --target-bytes 650000000 \ |
| --row-group-size 2048 |
| ``` |
|
|
| Checksum generation and verification: |
|
|
| ```bash |
| .venv/bin/python release/v5_hf/tools/write_checksums.py --package release/v5_hf |
| .venv/bin/python release/v5_hf/tools/write_checksums.py --package release/v5_hf --verify |
| ``` |
|
|
| Full package validation (run from the repository root; the JSON report is written beside `v5_hf`, not inside the package): |
|
|
| ```bash |
| PYTHONDONTWRITEBYTECODE=1 .venv/bin/python release/v5_hf/tools/validate_release.py \ |
| --package release/v5_hf \ |
| --source data/synth/v5 \ |
| --report-json release/v5_validation_results.json |
| ``` |
|
|
| The sample selection seed is `20261031`. The Parquet schema carries Hugging Face `Image` feature metadata and passed the local Arrow smoke test. Hugging Face's dataset-card YAML validation endpoint accepted the README metadata. A live viewer render remains **UNVERIFIED** until the shards are uploaded. |
|
|
| ## Remaining review notes |
|
|
| - Wikipedia article-level IDs/URLs were not retained. This package uses dataset/shard-level credit as requested; the sufficiency of aggregate attribution under the upstream CC BY-SA terms remains **UNVERIFIED**. |
| - The Noto Sans Hebrew binary's embedded copyright year differs from the downloaded upstream OFL notice; this is disclosed in `ATTRIBUTION.md`. The exact matching notice revision remains **UNVERIFIED**. |
| - No dataset or code was uploaded to Hugging Face. |
