Regional DDR repair could clear DRC errors by putting vias in signal pads, even with allowViaInPad set to false. On a real A13 circuit forbidden vias went from 3 to 0 after the fix, with 7 other clearance errors still open. An automated fixer optimizing for "DRC clean" broke a rule the designer had set.
