SolEx is the foundational extraction bureaucracy of late Sol, born from the merger of Horizon Ventures transport infrastructure with TerraCore Industries mining and life-support administration. It governs through throughput, audit, and contract inheritance.

Before Sol Dominion turned hierarchy into explicit doctrine, SolEx had already taught much of the solar economy to think in those terms. It treats worlds, habitats, labor pools, and transport corridors as linked inventories to be optimized and defended.
