During multi-sample re-ranking, the judge model evaluates the full set of candidate snippets multiple times per round to derive a stable median rank and extract rationale from the canonical sample.
sequenceDiagram
participant O as Optimizer Loop
participant R as Ranker Model
participant S as Statistical Median
O->>R: Sample 1: Evaluate candidate + competitors
O->>R: Sample 2: Evaluate candidate + competitors
O->>R: Sample N: Evaluate candidate + competitors
R-->>S: Return N ranking orders & rationales
S-->>O: Compute median rank & canonical rationale
