Scratchy: Visual-Scratchpad Multimodal Reasoning for Cryptographic Proof Generation in EasyCrypt: A typed proof-relation graph raised accepted EasyCrypt proofs to 54 of 256 versus 24 for shuffled edges, but the graph is compiled from a hand-written sketch that already names the tactic.

When LLMs Invent Rust Crates: An Empirical Study of Hallucination Patterns and Mitigation: Across 14 models and 2,794 tasks, LLM Rust code names crates absent from the reference inventory; a hallucinated name alone is not evidence of malicious installation.
A Survey on LLM-Integrated Hardware Design Verification: Hardware verification agents can optimize tool acceptance and select provable but vacuous or misaligned properties, so acceptance by a checker is not evidence of intent.
Debug like a Human: A Large Language Model Debugger via Verifying Runtime Execution Step by Step: LDB debugs LLM-generated programs by checking each basic block’s entry and exit variable states with LLM verdicts, raising GPT-3.5 HumanEval Pass@1 from 73.8 to 82.9.
