Both sides assume: Beneath five lines of disagreement, the combatants share a load-bearing frame: that a cost model, fed the right numbers, is the right way to settle a national technology choice, and that its outputs deserve headline status even as every party concedes under pressure that those outputs move with the assumptions. They also share more specific ground: nobody disputes the coal fleet is exiting, both models use similar nuclear build costs per kilowatt, and both publish sensitivity results their own headlines ignore. The AAP FactCheck's finding that both major parties overclaimed is the shared assumption's receipt.
