HOME

The first four books built a map of relation, return, physical occupation, and readout. HOME shows how any civilization can enter it and return recognizably.

Every civilization begins from a local address: its own repeatable interval, convention plants, and numerical coordinates. Rosetta Lane is the illuminated route. Light keeps space and time mutually readable while one unique reversible UnitMap carries the same held relation through changed coordinates.

Humanity's SI becomes a worked example, not the universal template. The Standard Model's nineteen coordinates keep their own physical job while their dimensional reports translate. Neutrino masses move between charts while PMNS geometry and oscillation probability hold. Gravity's curvature, stress, coupling, and comparison length move together while their pressure/answer relation remains fixed.

HOME completes Light-Space Theory's declared UnitMap home stretch: one illuminated architecture, many civilization conventions, and a lawful return between them. Home is not the same coordinate everywhere. It is the same return.
