| # Data layout v4 (2026-10-01), read-only; fixes ship as a new version | |
| Same content and rules as release v3.1 (old layout, `/run/media/than-minh/Thesis/Thesis-datasets/releases/2026-10-01-v3.1/CONTRACT.md`, which carries the v2 and v3 text). Changes in v4: | |
| 1. Layout: `<dataset>/{runtime,scorer,latents}`; no `dev/`, `final/`, `main/` view folders. Meta `release=v4`. | |
| 2. BRACS: one catalog on the final protocol (bank 460 = train+val, query 87 = test) plus table `split_info` and `bracs/slides.csv`. The dev protocol (bank train 395, query val 65) is derived by masking val; the old dev catalogs are in the archived v3.1. | |
| 3. `latents_index.path` is relative to the dataset folder (`latents/<slide>.pt`); `sha256` is filled (tensor-file hash). | |
| 4. Not carried over (archived): GDC report PDFs and OCR text (the report text is in the TCGA bank catalog as `path_report_full` / `path_report_diagnosis`), logs, staged knowledge work and scripts, the latents manifest. | |
| 5. Everything under `<dataset>/scorer/` is scorer/owner only. | |
