Struct GraphResult 

pub struct GraphResult {
    pub headers: Vec<String>,
    pub rows: Vec<Vec<Value>>,
}

Dynamic header-keyed result table returned by StoragePort::graph_traverse.

headers carries column names in row order; rows are row-major with rows[i].len() == headers.len(). The shape is wire-additive: backends MAY append new columns without breaking older consumers, and consumers SHOULD locate columns by header name (not positional index) when they need optional metadata.

Canonical columns (Plan 03-03 + P0 #4 Wave 3)

The Graph::anchored operator emits a Cypher RETURN whose canonical header order is:

Header	Type	Meaning	Default if missing
id	hex str	m.id_hex — destination entity’s 16-byte ULID, hex.	"" (empty hit)
name	str/null	m.name — display name.	null
type	str/null	m.type — entity type tag.	null
path_length	int	Number of edges traversed (length(path)).	row index i
edge_weight_product	float	product of coalesce(r.weight, 1.0) over path edges	1.0
anchor_confidence	float	Confidence of the seed entity that anchored this path.	1.0

The first three are required by the operator today (positional read for back-compat with all canned_graph_with-shaped test fixtures). The last three are optional: when absent, the operator substitutes the documented defaults so the scoring formula reduces to the legacy 1.0 / (1.0 + i).

Fields

headers: Vec<String>

rows: Vec<Vec<Value>>

Row-major; column count must equal headers.len() for every row.
