   Yes, that would help. On the SF1000 setup:
   
   1. q64 with `spark.sql.exchange.reuse=false`. If the reuse problem is the 
cause, it should stop returning 0 rows.
   2. For a run that still returns 0 rows, the final executed plan. A 
`ReusedExchange` under the second `cross_sales` reference that points at the 
other year's `store_sales` join would confirm it.
   
   The fixes are up: #6268 for the q5 failure (Parquet and Iceberg native 
scans) and #6270 for the q64 row loss. A build of main with both applied, run 
at SF1000, is the check that matters most. If q64 still comes back empty with 
AQE off, the plan from that run would help too.
