What you’re looking at.

The enacted map

The districts a state actually used that cycle — U.S. Census shapefiles, colored by the real U.S. House result. Its seat tally is the official, documented outcome.

The neutral baselines

Splitline and ReCom redraw all 435 seats from population and geography alone — no map-maker, no partisan or incumbency input, reproducible from a published rule.
