pub const RRF_WEIGHT_GRAPH: f64 = 1.0;Expand description
R3 (Slice 30) — graph arm RRF weight. Conservative starting value (equal to
RRF_WEIGHT_VECTOR). Without R2 per-class delta data the graph arm weight
cannot be calibrated; 1.0 is the minimum non-zero contribution. The graph
arm surfaces newly-reachable nodes from BFS traversal; it is not meant to
override the primary text/vector signals. Revisable after R2 data arrives.
