Use whenever a ghostgrid CI failure needs fixing, whenever you see ruff or pylint output with rule codes, whenever pylint R0801 duplicate-code fires, whenever cv2 triggers pylint no-member, or whenever you're about to push and want to pre-empt the common failures. Contains the catalogued fix for every error class that has appeared in ghostgrid's CI history, plus the local-verify command for each.
