Harmonic announced Aristotle, an AI system for verifying code, launching with support for C and Verilog, aiming to verify the flood of AI-generated code.
A user pointed Aristotle at TorchLean's C runtime: in about 6 hours it proved 211 of 213 properties (memory safety, reference counts, functional correctness). The remaining two came with a use-after-free counterexample involving inconsistent caller reference counts; the team is reviewing ownership assumptions and proof artifacts to establish exactly what's guaranteed.
