Projected 66 yea of 100 voting; 90% interval 42–95 (quartiles 52–82). Intervals are backtest-verified to cover ~90%.

Filibusterable: the realistic Senate line is 60 votes — P(≥60) = 51% (simple-majority P = 92%).

Procedure	Likelihood	Projected yea	Passes
conference	5%	67 [41–96]	94%
passage	95%	66 [42–94]	91%
