Structural constitution
Every environment begins as a structural system. Spatial grids, circulation, volumetric hierarchy, and operational logic are fixed at the Prototype level and remain constant across all editions.
COS operates on these systems. Authorship and identity are applied within their boundaries.
Structural layer beneath authorship
The Prototype – Structural Layer
The Prototype is spatial structure, circulation logic, and operational constraint. It constitutes the non‑aesthetic foundation of each asset and remains invariant across uses and operators.
The Signature – Authorship Layer
The Signature is applied after the Prototype as an authored layer. It defines geometry, chromatic zoning, rhythm, and atmospheric conditions within the constraints of the structural system.

Territorial Systems
Invariant systems
Each Prototype is invariant across deployments. Programs, operators, and authored identities vary; the structural system remains constant.
Deployment follows a fixed sequence: Prototype selection, parameter integration, authored application.
EURAN as structural intelligence
EURAN defines structural systems for shipyards, developers, architects, and operators. The Prototype Series establishes this role across maritime and terrestrial assets.
226, 326, and 426 constitute the COS structural language.
