The held endpoint changes the landing
The same 4830 → 4900 expansion has two different coordinate realizations.
4830 × 70/69 = 4900
Increase: 70 years
4836 BC moves to
Christ-generation hinge
4906 − 6 = 4900
6 BC moves to
Schematic Enoch position
4836 + 65 − 1 = 4900
The extension is also exact:
6 + 65 − 1 = 70 years.
Sources: File 46 L2 / §2.2: forward endpoint AD 65 · File 46 §4.2: backward endpoint 4906 BC.
Both constructions apply 70/69 to 4830, producing 4900 and adding 70 years. Holding 6 BC fixed and extending backward gives 4906 BC. Holding the schematic Enoch position 4836 BC fixed and extending forward gives AD 65. The forward elapsed span is 4836 + 65 − 1 = 4900; the extension from 6 BC to AD 65 is 6 + 65 − 1 = 70. These are anchored span expansions. Crossing BC–AD here does not activate a Mirror reflection.
