Abstract:Package managers are legion. Every programming language and operating system has its own solution, each with subtly different semantics for dependency resolution. This fragmentation prevents multilingual projects from expressing precise dependencies across language ecosystems; it leaves external system and hardware dependencies implicit and unversioned; it obscures security vulnerabilities that lie in the full dependency graph. We present the \textit{Package Calculus}, a formalism for dependency resolution that unifies the core semantics of diverse package managers. Through a series of formal reductions, we show how this core is expressive enough to model the diversity that real-world package managers employ in their dependency expression languages. By using the Package Calculus as the intermediate representation of dependencies, we enable translation between distinct package managers and resolution across ecosystems.

The first version of Mog was created entirely using the Volt coding agent, the vast majority of which used a single continuous session spanning over three weeks, using Voltropy’s Lossless Context Management to maintain its memory after compactions. This session ported the QBE compiler to safe Rust. The models used were Claude Opus 4.6, Kimi k2.5, and GLM-4.7.
