Research changelog · TFPT — Introduction and reading guide
The mark-local [formula in source] implication is now Lean-formalised ( SeamDeckClosure.lean, ledger FORM.QGEO.01, ). A new module in the carrier-rigidity Lean project machine-proves the algebraic core of v201/ v210 ( audit: pass, no sorry/ admit, no domain axioms — \#print axioms [formula in source] propext, Classical.choice, Quot.sound only): (i) the [formula in source] th-root character orthogonality [formula in s
