 - Contains the **first 10,000 proofs** from the ~45,000-theorem Metamath database  
 - Each example is a **directed acyclic graph** (DAG)  
-- **Node features:** 768-dimensional **CodeBERT embeddings** of Metamath statements  
-- **Labels:** the **theorem required to justify each node**  
+- **Node features:** 768-dimensional CodeBERT embeddings of Metamath statements  
+- **Labels:** the theorem required to justify each node (axioms and assumptions have the same label) 
 - **Conclusion masking:** the conclusion node’s embedding is zeroed out so the model must predict the final logical step directly from the graph structure and the other nodes  
 - **Rare labels** (<=5 occurrences) are collapsed into a single UNK class  
 - **All theorem statements** (not just proofs) are included in training, since the model must treat theorems themselves as prior knowledge
