   Thanks for the review @cloud-fan , have addressed the blocking item: 
captured `legacyNullInEmptyBehavior `at construction (mirroring `InSet`) and 
added the empty-result short-circuit before `child.eval` in `evalMultiColumn`. 
   
   Confirmed a plain WHERE IN gets rewritten to LeftSemi before 
`PlanSubqueries` runs, so the regression forces the `InSubqueryExec` path via a 
FULL OUTER JOIN ON condition (same pattern as the other tests here) and 
verified it reaches `evalMultiColumn` and that the division-by-zero LHS doesn't 
throw under ANSI. 
   
   Can you PTAL again? Thanks!
