# Suture

Gold tasks for **policy-issuance QC**: a structured underwriting binder, a structured issued policy, and the exact discrepancy set. Images are **not** stored. Re-render with `suture_forge.generate.render_doc` from the GitHub repo.

Paper and adapter: [caiotheodoro/suture](https://github.com/caiotheodoro/suture) · [`caiotheodoro/suture-8b`](https://huggingface.co/caiotheodoro/suture-8b). Predictions on this gold: [`caiotheodoro/suture-evals`](https://huggingface.co/datasets/caiotheodoro/suture-evals).

## Splits

| Config | Seed | n | What |
|---|---:|---:|---|
| `benchmark` | 777 | 1000 | Contracted held-out set. Never in train. |
| `validation` | 7 holdout | 80 | Val. Optimistic vs 777; `DEDUCTIBLE_HIGHER` gold n=0. |
| `train` | 7+11+13+17+19+23 | 5120 | Published SFT mix (`train_dedhi`). |
| `train_seed7` | 7 | 320 | Official stratified split, no class boost. |

Leakprobe vs val and vs benchmark is **0**. Signature = SHA-256 over sorted ground-truth fields. Build refuses overlap > 0.

## Row schema

Each line is a `Task`: `task_id`, `seed`, `binder`, `policy`, `image_*_sha256`, `expected` (`PASS`/`FLAG` + discrepancies), `signature`, `difficulty`. Taxonomy and weights: repo `CONTRACTS.md` (13 classes).

## Render

```python
from datasets import load_dataset
from suture_forge.schema import Binder, Policy
from suture_forge.generate import render_doc

row = load_dataset("caiotheodoro/suture", "benchmark", split="train")[0]
png = render_doc(Binder.model_validate(row["binder"]), "BINDER",
                 row["difficulty"], row["task_id"])
```

Linux vs macOS raster can differ (SHA mismatch). Labels do not. Eval in the project re-renders on the GPU host.
