pub const GRAPH_CACHE_VERSION: u32 = 3; // 3u32Expand description
Persisted graph cache schema version.
Bump this whenever the serialized shape of the persisted graph (any of the
graph types that derive serde for the cache, the manifest types, or the
store envelope) changes, so a stale graph-cache.bin written by an older
binary is rejected rather than deserialized into the wrong shape.
