proof is a such as the result of . Each premise becomes an , each derived step a with a tactic proof, and the goal the theorem.

Types are carried as expression trees; step proofs are emitted as Lean tactic blocks (, , , ). The result therefore round-trips through into compilable Lean source.

Because the transpiled environment is real Lean, you can re-check it - opening the with and confirming it auto-completes verifies the transpilation.
