Module schema 

Arrow schemas for code graph objects.

Two tables:

• CodeNodes: functions, classes, modules, files — the objects in the code graph
• CodeEdges: calls, imports, inheritance, containment — relationships between objects

V12a-1 additions (EX-3168)

V12/V13 parity audit: V12/V13 Python had no position metadata and no Rust-specific node kinds. All position columns and Rust-specific CodeNodeKind variants are new work, not ports from V12.

Position columns (13–18) are nullable — backward-compatible with existing Parquet files. New Parquet files produced by the Rust tree-sitter parser (EX-3120) will populate them.

Modules

edge_col

Named column indices for the CodeEdges schema.

node_col

Named column indices for the CodeNodes schema.

Structs

CodeEdge

A code edge record for batch building.

CodeNode

A code node record for batch building.

Enums

CodeEdgePredicate

Kind of relationship between code objects.

CodeNodeKind

Kind of code object.

Constants

CODE_EMBEDDING_DIM

Default embedding dimension for code objects.

Functions

build_code_edges_batch

build_code_nodes_batch

code_nodes_schema

Schema for the CodeNodes table.

extract_file_path
