The Init module export from Lean 4 core.

This test contains the fundamental building blocks of Lean 4, including:

  • Basic data types (Nat, List, Array, String, etc.)
  • Core tactics and syntax
  • Foundational mathematical structures
  • Essential metaprogramming infrastructure

This is one of the smallest meaningful test cases, making it ideal for initial checker validation and debugging.
