Larger Than the Library

Fermat's margin was too narrow. This one is larger than the library it sits on.

Thirteen million lines. About twenty-nine thousand five hundred intermediate theorems. Eleven days. Lean printed PROVED at a clock time.

Formalization is looking if you stay with every step forced into the open. Late mouth if you mean the green root is the understanding.

Almost nobody will read the thirteen million lines.

The leftover is both: the checkmark that finally sits, and the unread mass that makes the check possible.

The agents lost the project state until a DAG held what still needed proving. That sat still. The margin did not.
