The New Generation Flip

Before alignment KDP had a bypass route
42
KDP + quota
25
PUK + quota
15
New Generation
51 to govern
KDP path: Could ally with New Gen (42+15=57) and govern without PUK, as it did with Gorran before.

After alignment PUK closed the bypass
42
KDP + quota
25
+15
PUK bloc = 40
51 to govern
KDP stuck: No path to 51 without PUK. The blocs are now 42 vs 40, and neither can govern alone.
What changed: New Generation was the swing bloc. When it aligned with PUK, the KDP lost its only alternative to a genuine coalition with PUK. The leverage shifted from "we can go around you" to "we need each other."
