cvx-graph — Knowledge Graph for ChronosVector

Provides a typed property graph for compositional reasoning over entities and their relationships. Designed for:

• Task structure: "heat_then_place requires steps: find→take→heat→take→put"
• Shared sub-plans: "clean and heat share find→take prefix"
• Constraint validation: "after take, valid next actions are go/use/put"
• Cross-entity transfer: "entity A is-similar-to entity B"

Graph Model

• Nodes: typed entities (task, action, object, location, step)
• Edges: typed relations (requires, precedes, located_at, similar_to)
• Properties: key-value attributes on nodes and edges
