| Tp:verdict Reason | The dataset or training/evaluation relationship is grounded in the staged manuscript. | [1] |
| Tp:verdict Reason | The claimed model property matches the parsed model-property table in the staged manuscript. | [1] |
| Tp:verdict Reason | The claim is source-grounded in the manuscript, but the artifact-availability requirement is blocked by missing exact code/model-card/data URLs. | [1] |
| Tp:verdict Reason | The manuscript states the visualization interpretation, but no embeddings or figure-generation data are available for quantitative verification. | [1] |
| Tp:verdict Reason | The claim is source-grounded, but the unit's executable recomputation requirement is blocked by missing experiment artifacts. | [1] |
