Isabelle-extreme [work] Guide

If you’ve ever wondered, “What is the absolute minimum logic needed to build an ITP?” – isabelle-extreme is your answer.

Beyond the Mainland: Exploring isabelle-extreme , the Minimalist Core of Interactive Theorem Proving isabelle-extreme

isabelle-extreme is the "assembly language" of the Isabelle ecosystem – raw, unforgiving, and beautiful in its simplicity. While you will never ship a verified compiler written in it, exploring it offers a rare glimpse into the foundational bedrock on which massive proof developments rest. If you’ve ever wondered, “What is the absolute

Also known as (EXperimental TRansformational Equational Mathematics Engine), this is not a new front-end or library. It is a radically stripped-down meta-logic – the absolute minimal core needed to perform interactive proofs within the Isabelle framework.
