The foundational-layer coordinate for the infrastructure that agents run on.
A technically precise string naming the base layer — the memory, compute, state, and runtime primitives — that autonomous agents require to operate.

Why this is canonical
'Substrate' in computing refers to the underlying execution environment: hardware, runtime, operating context. Applied to agents, 'agent substrate' names the foundational infrastructure layer that is distinct from orchestration, tooling, or application logic. The .ai TLD places this at the agent-era primitive layer.
