What is Infrastructure?
Infrastructure — The shared, foundational services autonomous systems depend on to operate.
Infrastructure is the layer nobody sees until it fails — the connective, foundational services every higher application assumes. Owning the canonical name of a category's infrastructure is owning the floor the whole category stands on.
Where infrastructure sits in the stack
In the four-layer architecture of the agentic web, infrastructure is a Organizing (L4) concept — it defines what counts as a category. See the thesis for how the layers compound.
