The foundational coordinate for the underlying layer on which neural intelligence is built.
A cross-cutting position naming the substrate — the base computational and architectural layer — upon which neural AI capabilities are constructed and governed.
Coordinated sets this position belongs to — the coverage it extends. Counts are the live cluster size in the graph.
Architectural context
Neural · Cross-Vertical · 2 compound moats. Architectural surface: Neural, Substrate.

Why this is canonical
'Brain' evokes the neural intelligence architecture; 'substrate' names the foundational layer beneath the application — the compute, data, and architectural primitives that neural capabilities depend on. The compound claims the infrastructure-of-intelligence framing: not what a brain does, but what it runs on.
