Beam search: beam width is enforced independently per batch item · case 03
beam width is enforced independently per batch item.
Case contract
Rows are [batch,score,hypothesis]; return up to width highest scores per batch, ordered by batch then descending score and hypothesis name.
Why this case matters
Beam decoders rely on consistent hypothesis state while expanding and ranking candidates.
One recorded failure

| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| one per batch | [["b", 6, "w"]] | [["a", 5, "y"], ["b", 6, "w"]] | Failed |
