Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
The following bugs have been fixed - The implementation for the `Expr.proj` rule did not match our paper nor `RC.lean`. The correct rule is: ``` | Expr.proj _ x => whenM (isOwned x) $ ownVar z ``` - We take the OwnsetSet (`O` in our paper) into account when computing the fixpoint. - `applyParamMap` and `mkInitParamMap` were not visiting the alternatives of `case` statements. |
