A node in the code knowledge graph as stored in (and read from) the DuckDB database.

Fields

id: String

Stable unique identifier, e.g. fn:src/lib.rs:parse or file:src/lib.rs.

kind: String

String form of [NodeKind], e.g. "Function", "File".

name: String

path: String

Repo-relative file path.

line_start: u32

line_end: u32

language: String

churn: f64

Normalised commit-frequency score over the last 90 days (0.0–1.0).

coupling: f64

Normalised co-change coupling score (0.0–1.0).

community: i64

Community ID assigned by the Louvain clustering pass (0 = unclustered).

in_degree: i64

out_degree: i64

exported: bool

Whether the symbol is publicly exported from its file.

is_dead_candidate: bool

Whether dead-code analysis flagged this node.

dead_reason: Option<String>

complexity: f64

Cyclomatic-complexity-derived score (higher = more complex).

is_test_file: bool

test_count: i64

Number of test functions in this file (only set on File nodes).

is_tested: bool

Whether at least one test exercises this symbol.
