| # Reproduction and integrity checks | |
| From the dataset root: | |
| ```bash | |
| git lfs pull --include='matrices/**' | |
| sha256sum -c manifests/SHA256SUMS | |
| python -B scripts/verify_dataset.py . | |
| ``` | |
| The verifier uses only Python's standard library. It reads the materialized | |
| compressed Matrix Market files, checks their content and file hashes, verifies | |
| `H_X H_Z^T = 0` over GF(2), recomputes both ranks and `k`, checks the strict | |
| FOM arithmetic, and validates every included logical witness against the | |
| published matrices. The Stage 3 typed-exact verifier additionally reconstructs | |
| the twisted `Hx/Hz`, validates the complete `Gx/Gz` logical basis, and | |
| replays the weight-16 upper witness under the stated pinned-solver boundary. | |
| The exact public pipeline parameters and source bindings are recorded in `config/run_config.public.json` and `manifests/selection.json`. Full stochastic search replay requires the source revision and matching dependencies; this compact expert package intentionally omits model transcripts, internal prompts, process state and checkpoints. | |
