Could you build this?

No This is a Rocq (Coq) proof-assistant formalization of lambda calculus with partial substitutions, which is research-grade work requiring expertise in type theory and mechanized proof.

What it would actually take: Building an equivalent requires expertise in dependent type theory and the Rocq proof assistant, plus a solid understanding of lambda calculus metatheory such as substitution lemmas and confluence. Developing and checking the proofs is the hard part and cannot be bypassed with AI-generated code alone.
