Researchers have developed a new calculus for analyzing translations between programming languages, focusing on the trustworthiness of answers derived from these translations. This system models translations as a graph with varying trustworthiness levels, allowing for composable contracts that specify assurance, direction, and observable data. The core of this system is mechanized in Lean 4, with an implementation called hurdy-gurdy that operates on two planes: a use plane for LLMs to generate evidence-carrying answers and an evolution plane for managing the graph's growth. The architecture is designed to continuously improve fidelity by recording unmet questions and registering new translations, with a snapshot in July 2026 revealing defects in the authors' own work.
