Why collections matter
Context reveals whether movement is isolated or shared.
Collection-wide breadth and activity help distinguish a single-item event from behavior affecting an ecosystem. Production indexes must publish constituent and weighting methodology.
Entity model
Game → collection → item → event.
The prototype treats relationships as first-class data so research can move through the Steam item world without relying on flat search results.
