04 / What a route meansCount status-bearing paths, then preserve the legal differences.
One unit is one jurisdiction route. A route follows a named polity or a modern jurisdiction precursor through a legal-status change; it does not measure land, people, wealth, or legitimacy.
Acquisition cohorts use each modern jurisdiction’s primary route from the source ledger. Mixed present-state geographies remain in provenance notes rather than being split into unsupported fractions.
The Confederate branch represents secession ordinances, de facto government, loss of ordinary Union representation, and later Reconstruction. It does not imply U.S. recognition that the states lawfully ceased to be part of the Union.
Colonial administration is not one legal category: occupation, possession, international trusteeship, treaty control, unincorporated territory, and sovereign free association remain distinct in labels and tooltips.
