**Reproduction:** Stream a finished GROUP BY table through an MSE leaf; keep its owned rows behind a cursor with a cached List fallback instead of copying all row references. **Validation:** 27 leaf + 9 streaming tests, scoped checks, and independent review passed. Paired 3-JVM/50k-row component comparisons saved ~200 kB/batch and 10–24% COUNT / 26–34% bitmap current-thread CPU; end-to-end gains are unmeasured. -- This is an automated message from the Apache Git Service.
