John Rawls
The closest ancestor in the register: the constitutional spine and the veil, imported as a graduated debiasing vote; diverges on sufficientarian floors not maximin, and a ten-axis capability metric not primary goods.

What we took
The closest ancestor in the register. Priority-of-right, moral-arbitrariness and the common-asset view, which grounds rent-to-commons, the basic structure, and the veil, imported as a graduated debiasing vote that finalises how a democratic vote makes value objective-for-governance. Plus the lexical-then-weighted architecture, the just-savings posterity axis, and self-respect as the master good.
Where we diverge, and how we answer
Diverges on exactly two points: sufficientarian floors, not maximin (a value vector is threshold-commensurable but not maximand-commensurable); and a ten-axis capability metric, not primary goods, completing his own "normal range" bracket. It adds an anti-concentration ceiling for the fair value of political liberty.
The net position
The closest ancestor in the register, the constitutional spine adopted almost whole, with two conscious, bounded departures.
