Henad — unity beyond the vehicle
Proclean divine unity
The henad point marks unity beyond the differentiated vehicle shells in a Proclean frame. It is placed above the crown to preserve the diagram's vertical transcendence metaphor, not to imply that a henad is a human cranial structure or a personal possession.

The middle propositions on the divine unities and their relation to the intelligible order provide the Proclean context for the henad; the crown coordinate is a symbolic editorial placement.
