More than linked pages
The graph contains nodes and assertions between them. Hugo pages provide storage and presentation here, but graph membership comes from node metadata, not a path. An incoming connection is derived from a source’s outbound edge.
Useful expressions
The same graph can support navigation, indexes, machine exports, and grounded AI context. Those are implemented transformations, not capabilities that appear simply because content is written in YAML.
Keep the graph small enough to understand. Evaluate its value through the questions it helps answer and the expressions it helps create.
