| # SCAR Evaluation Set |
|
|
| **838 held-out contrastive pairs** for evaluating smart contract vulnerability retrieval models. Constructed as a 10% stratified holdout from training sources plus the 91 original FORGE-Curated pairs (temporal holdout). |
|
|
| The split is performed at the **report level** — not the finding level — to prevent information leakage. Hash-based verification (SHA-256 on normalized source) confirms zero code overlap with [`scar-pairs`](https://huggingface.co/datasets/Farseen0/scar-pairs). |
