nusy-codegraph — Code as a live Arrow object graph.

Parses Python source files via tree-sitter into CodeNodes (functions, classes, modules) and CodeEdges (calls, imports, inheritance, containment). All data stored as Arrow RecordBatches for zero-copy query and versioning via nusy-arrow-git.

Architecture
