Question
[smooth-4d-poincare] Produce a status report or a checkable solution for: Smooth 4-dimensional Poincare conjecture. Statement: Is every smooth homotopy 4-sphere diffeomorphic to the standard 4-sphere S^4? If unsolved, report the best partial results and references. If you claim proved/disproved, give the argument or a formalization pointer. Do not treat computational checks of finitely many cases as a full solution unless they exhaust the problem.
