  The construction of soft noncommutative schemes via toric geometry in
arXiv:2108.05328 [math.AG] (D(15.1), NCS(1)) can be generalized and applied to
a commutative scheme with a distinguished atlas of reasonably good affine local
coordinate charts. In the current notes we carry out this exercise for flag
varieties.
