One hinge, two alternative expansions
The 6 BC hinge stays fixed as the span expands backward through schematic genealogy positions.
4836 − 6 = 4830
Original span · schematic genealogy positions
4830 × 70/69 = 4900
Increase: 70 years · schematic genealogy positions
4830 × 25/23 = 5250
Increase: 420 years · schematic genealogy positions

In File 46’s genealogy lattice, Enoch occupies 4836 BC, Jared 4906 BC, and Adam 5256 BC. These are calculated positions on the 70-year genealogical grid, not ordinary historical birth dates. Holding the 6 BC Christ-generation hinge fixed, 4836 − 6 = 4830; 4830 × 70/69 = 4900 places the earlier endpoint at 4906 BC; 4830 × 25/23 = 5250 places it at 5256 BC. The gains are 70 and 420, respectively. The factors are alternatives; the second row is not fed into the third.
