### Description <!-- If this is your first contribution to Lucene, please make sure you have reviewed the contribution guide. https://github.com/apache/lucene/blob/main/CONTRIBUTING.md --> Lucene https://github.com/apache/lucene/pull/13408 (released in 10.0) dropped a guard in `BooleanScorerSupplier.optionalBulkScorer` that previously kept `TOP_SCORES + minShouldMatch > 1` queries on `WANDScorer`. As a side effect, when matches are dense, dispatch now lands on BooleanScorer, which has no top-K impact pruning — causing 10–100× latency regressions on pure-should compound queries with minimumShouldMatch > 1. -- This is an automated message from the Apache Git Service.
