NumPy 2.5 after work: sort(..., descending=True)
NumPy 2.5.0 (21 Jun 2026) is a transitional release: Python 3.12–3.14, distutils gone, array-API descending sorts on np.sort / np.argsort. Follow-ups 2.5.1 (4 Jul) and 2.5.2 (9 Aug 2026). NaNs still sort to the end. Three things to try tonight. Not investment advice.
