Mathematics to a typed proof obligation

Live Formalization

Render a sampling-theory statement, inspect a reviewed or deterministic Lean candidate, run the pinned compiler locally, and export into the ASTIS Substantive Advance workflow.

Statement and context

LaTeX statement

Plain-language interpretation

Source anchor Preferred module

Formal candidate

Lean source

A successful compile checks this exact snippet. It does not establish source equivalence or prove an unfilled theorem.

Local execution policy

The compiler service binds only to loopback, serializes compilation, limits request size and time, writes snippets only to a system temporary directory, and never modifies repository source. It is a developer tool, not a hardened public code-execution sandbox. Keep it behind the documented private preview path.
