Formal Verification Of Code Properties With Lean Integration

Lean 4 paper (2021): https://dl.acm.org/doi/10.1007/978-3-030-79876-5_37

Unique: Automatically extracts code semantics and translates them into Lean specifications, then uses LLM-guided proof synthesis to verify properties, creating a fully automated pipeline from code to formal proof without manual specification writing

vs others: More automated than manual formal verification (Coq, Isabelle) because it eliminates manual specification and proof writing; more trustworthy than testing because proofs provide exhaustive guarantees

Imandra (ReasonML/OCaml) reasoning studio

Unique: Integrates Imandra's automated reasoning engine directly into the VS Code save workflow, enabling real-time formal verification feedback without requiring separate tool invocations or CI/CD runs, with counterexample generation and proof state visualization

vs others: More integrated and interactive than running Imandra as a separate CLI tool or in CI/CD, because it provides immediate feedback and visualization of proof failures inline in the editor as you code
