    Done via #264 (squash-merged). Acceptance bar green: lake build PadicLFunctions ✓, zero new sorry, #print axioms = [propext, Classical.choice, Quot.sound], statement byte-for-byte unchanged. Golf: gcongr for the hbd calc, by_contra!, inlined hn, dropped exfalso, stripped narrative comments. Body 40→33 lines.
