Materia

The substance layer: one page per item-kind — md for content, html for display, osmx for data. Types live here; tokens (who owns what, where) live in the Cadastre. Internal preview — publication posture decides at S-006.

Class pages

The anchor taxonomy (the brainstem)

These paths are the NEXUS embedding anchors — the grounded coordinate frame by which every future megacity.studio asset is filed, ranked, sorted, and stored. Client catalogs (e.g. materia-comics, the validated first overlay) live in their own repos and reference these anchors; they are not part of the anchor set.

Nexus = memory · Codex = structure · Materia = substance · Cadastre = situation.
