Fly Brain Hubflysim mushroom-body fix
maumcrez-svg
A whole repository for one transposed index, in flycoinrh, which is also listed here. The upstream code reads a post-by-pre weight matrix in the wrong orientation, so what it classifies as dopaminergic input is actually feedback from the output neurons, and any approach or avoidance readout built on it silently gets the sign backwards. A second fact kept the bug alive: the shipped graph deletes every dopaminergic edge, so the correct read returns zeros. The fix vendors upstream unmodified, and two strict expected failures pin the defect so that quietly repairing them turns the suite red.
