Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
Not only is this more semantically appropriate (see e.g.
`/usr/src/{linux,rust,...}` on Debian), it also prevents .ilean files
from Lake tests (which are symlinked into the build directory as part of
`src/` during development) from ending up in the built-in LEAN_PATH and
being watched & loaded by the server.
