| Deep Forensic Audit of All Repository Files & Live Streaming Reader |
| =================================================================== |
| 1. Audits every single file in ViuAI/viu-mini-raw-pretrain (1,974 files, 230 GB). |
| 2. Verifies exact schema and row counts. |
| 3. Performs LIVE streaming test on every active category. |
| 4. Explains the exact status of any remaining raw non-parquet files. |
