   > Thanks for flagging the overlap, @mhatipog. I checked #59445 — your PR 
landed the narrowed `hasCorrelatedSubquery` / `hasInOrCorrelatedExistsSubquery` 
guard before mine, and the fix is functionally identical. Happy to defer to 
yours as the primary.
   > 
   > One thing I noticed: the end-to-end tests in #59445 cover correlated 
scalar and EXISTS but not IN (`ListQuery`) subqueries through LIMIT. I have a 
test case for that in this PR — happy to open a small follow-up PR against your 
branch adding it, or you can grab it from here. Let me know what works.
   > 
   > I'll close this PR once #59445 is on track to merge. Nice work on the fix.
   
   Thanks @txwyy123, really appreciate you spotting the missing end-to-end IN 
coverage and offering to help!
   
   I added a projected IN regression case to #59445 earlier today (27c65ec), 
covering both LIMIT and OFFSET, so it looks like we've converged on the same 
test. Thanks also for digging into the Filter vs Project distinction.
   
   Happy to coordinate any remaining improvements. Appreciate the collaboration!
