Code underlying the publication: Building A Correct-By-Construction Type Checker for a Dependently Typed Core Language

This repository contains source code for the paper. We develop a correct-by-construction typechecker for a subset of Agda's internal language. This code assumes that the input has already been scope-checked and is presented to the core in a well-scoped form. The typechecker uses erasure extensively and doesn't develop any meta-theory, relying on the typing rules as the source of truth. The implementation was developed by the authors of the paper through 2023 and 2024.
