Neuroforger: certified violation witnesses for smart contracts verification via LLMs

This feed contains multiple programming-languages and formal-methods papers; the most security-relevant is "Neuroforger", a tool/workflow that combines LLMs, a new Solidity-based formal specification language (abstract types), type checking, and concrete execution to automatically generate and validate violation witnesses (executable PoCs / counterexamples) for smart-contract properties. Neuroforger represents specs as Solidity tests with existentially-quantified abstract-type variables and searches for concrete instantiations that produce executable counterexamples, reducing ambiguity from NL
