Struct SchemaBrief 

pub struct SchemaBrief {
    pub nodes: usize,
    pub labels: Vec<LabelBrief>,
    pub edge_types: Vec<EdgeTypeBrief>,
    pub commits: Option<u64>,
    pub roles: Vec<(String, Vec<String>)>,
    pub recipes: Vec<Recipe>,
    pub partial: bool,
}

What a memory store is: its labels, its edge types, how deep its history runs, who may read it, and the call that answers each kind of question.

Present on a store no repository was ingested into — the same GitSync-marker test the MCP server’s tool listing splits on — and absent on a code graph, which is described by its rankings instead.

Fields

nodes: usize

Live nodes, all labels together.

labels: Vec<LabelBrief>

Labels, most populous first, ties on the name.

edge_types: Vec<EdgeTypeBrief>

Edge types, most numerous first, ties on the name.

commits: Option<u64>

How many commits of history are still reachable — total above the horizon floor. A count, not an index: the newest commit edges_at, node_history and was_linked accept is one below it, which is what the as of recipe names. Some(0) on a store whose WAL was truncated and whose archives are gone, and then there is no as of recipe at all.

None when the budget ran out before it could be counted: the scan that answers it re-reads the WAL, so it is the first thing a spent budget drops. Unknown and zero are different answers, which is why this is an Option and not a zero.

roles: Vec<(String, Vec<String>)>

(role name, the labels it may see), sorted by name.

recipes: Vec<Recipe>

One worked call per question kind, in a fixed order.

partial: bool

The budget ran out while counting: every count above is a lower bound, the listings may be short of entries, and commits is None. Rendered, so a reader never mistakes a partial count for a complete one.
