Every node is a single piece of content. A Note in one of the four Rooms, or an episode of the Podcast. The map sits beneath the Library's curatorial discipline: short-form briefings, framework explainers, and case-led Notes for chairs, non-executive directors, and senior governance practitioners, with each Room owning its case spine and the Podcast pulling across all four. Lines show how they relate. Some are case-anchor spines that pull Notes through one organisation. Some are sibling references from one Room into another's territory. Some are Podcast pulls into a Note. One is the named exception that lets BP appear in two Rooms under two lenses. Hover any node to see only what it is connected to. Drag to rearrange.
The numeral inside a node is the Room number. The badge top-right is the connection count — how many other Notes or episodes the node touches.
