Era
One of four ordered movements — Foundation, Intelligence, Economy, Civilization — across ten to fifteen years.
Eras are dependency order, not marketing phases. Foundation is the person and the institutions around them; Intelligence is the model layer; Economy turns capability into livelihood; Civilization is the persistent world, the devices and the sovereign internet.
An era is complete when its capabilities are live, its promises are checkable, and the next era can be built without going back.
