A stratified universality development with traditional, visual, and formal companions.
Completion: Reading edition complete · Lean: Source available, no current pass · Confidence: Recorded written review
Before you start
Suggested background: Read the problem statement, recorded scope and open questions first. The program's definitions determine its subject prerequisites.
Recorded results and limits: Complete amended reading/source package. 75 components have mixed proved/imported/conditional/conjectural status. The reconstructed Lean core has no fresh compiler pass.
Remaining work: Compile the exact included core, authenticate the separate historical formal package, and preserve the mixed 75-component concordance.
The background advice is an editorial starting point. The work itself states its prerequisites and hypotheses.
