Not simply “5D”
The Luminous Second is not another rung in the popular 3D–5D ladder. Calling it 5D can turn pre-material relation into a location and confuse light-form with refined physical embodiment. Earlier bridge-language may remain historically, but the mature distinction should govern.
Form without dense biology
Forms perceived through the Luminous Second belong to relational intelligibility and light-form rather than dense biological organisms. Any being described as having biology, technology, environment and continuing activity in time still belongs to some mode of embodiment.
Continuity and allowability
The Luminous Second provides a wider relational field in which continuity need not depend upon the physical brain alone. This remains a Codex proposition rather than an empirically demonstrated mechanism. It should be held as architecture within the work, not presented as established physics.
