Could you build this?
No The product is a Lean formalization of the Stacks Project, algebraic geometry, with proofs checked by Lean. Its substance is research-level mathematics formalization, which requires deep expertise in both Lean and algebraic geometry.
What it would actually take: A real version requires formalizing thousands of results from algebraic geometry in Lean 4 with Mathlib, which means writing proofs that pass the kernel. This is research-grade mathematical work that AI assistants cannot yet do reliably without expert review. The team needs algebraic geometers fluent in Lean, plus a dependency-graph tool and a review process.
