Artifact for "Verifying Fault Robustness by Type Checking: A Verified Information-Flow Approach" (VMCAI 2027, paper #3141) Vadim Zaliva (25146471) Valerii Huhnin (25146480) Jeffrey S. Foster (25146483) Formal methods for software Programming languages fault robustness information-flow analysis type systems formal verification Lean 4 artifact evaluation <p>Artifact for the VMCAI 2027 paper <em>Verifying Fault Robustness by Type Checking: A Verified Information-Flow Approach</em>. Poison is a core imperative language whose type system tracks faulty (sentinel) values through data and control flow by information flow. The artifact contains the Ott specification, a Lean 4 executable typechecker and interpreter, the mechanised proof that type checking enforces fault robustness (no sorry, standard axioms only), and 111 example programs used as a test suite.</p><p>The archive contains a Docker image (linux/amd64, project prebuilt and tested), the sources, a README with instructions, and logs. Requirements: x86-64, 16 GB RAM, 4+ cores recommended, about 13 GB disk for the loaded image; no network needed after loading.</p> 2026-09-30T22:36:18Z Software Software 10.6084/m9.figshare.34037049.v1 https://figshare.com/articles/software/Artifact_for_Verifying_Fault_Robustness_by_Type_Checking_A_Verified_Information-Flow_Approach_VMCAI_2027_paper_3141_/34037049 MIT
