START WITH A REAL TARGET
Your atlas is waiting for a destination.
Choose a proved theorem or declaration capstone. Repositories supply the formal source; subject regions help you explore, but neither is itself a goal.

Projects worth walking toward.
Curated Lean formalizations and AI-math announcements, kept separate by evidence type and linked to primary sources.

Provenance is part of the interface.“Lean-built” means a public formal artifact is linked. “Announcement” describes a claim or research update and does not imply that every headline has a public certificate.
FIELD JOURNAL
Your standing learner state
Facet coverage and evidence are permanent account data. Certifications use a 60-day freshness window; old work stays in the ledger but gently re-fogs.
