the researcher's note

Lean 4 / mathlib formalisation of Fermat's Last Theorem (Sept 2026, ~13M lines; Wiedijk's list). A proof assistant: kernel and tactics hand-written, the guarantee deductive, not fitted. LLMs assisted some contributors, but the artefact that does the deed is not a learned system. A landmark, not an entry.
