Fields

schema_version: u32

engine_version: u32

Property-graph engine generation that produced this graph (see super::GRAPH_ENGINE_VERSION). Bumped whenever edge extraction changes, so a graph built by an older engine — e.g. before the C#/Java type_ref edges existed (GH #398) — is rebuilt instead of silently served without the new edges. Graphs written before this field existed deserialize to 0.

built_with: String

lean-ctx version (CARGO_PKG_VERSION) that built this graph, recorded for diagnostics. Empty for graphs written before the stamp existed.

project_root: String

Absolute, normalized project root this graph was built for. Recorded so the one-way graphs/<hash>/ directory can be pruned when its project no longer exists on disk (#696 C4 — replaces the project_root the retired JSON index used to carry). Empty for graphs written before this field.

built_at: String

RFC3339 timestamp (UTC) of the last successful build.

git_head: Option<String>

Git HEAD (short) at build time, if available.

git_dirty: Option<bool>

Git dirty flag at build time, if available.

nodes: Option<usize>

Node count after build.

edges: Option<usize>

Edge count after build.

files_indexed: Option<usize>

Number of source files processed during build (before filtering).

build_time_ms: Option<u64>

Build duration in milliseconds (best-effort).
