Network Topology — the wiring census

Before any eigenvalue: is this even a web? Where CAN feedback live? The topology census answers with components, circular cores and density — and doubles as the edge-first quality gate for new templates.

How it reads

circular_cores[] = the sub-webs where loops exist at all; is_dag=true means no feedback anywhere (fragility reads differently). Density and degree tables set expectations for the heavier lenses.
