Every family has a Rook.
Forks happen. Licenses change. If a branch of your tree is marked estranged, it simply means the family has stopped comparing outputs.
Merges are increasingly common.
Since 2027, more models have two parents. Lineage traces both lines, and gently notes when they were already related.
