Review Comment:
@silundong I took a closer look at your query — appreciate the effort on
this! One thing I noticed: when we fire `RelOptUtil.getVariablesUsed(join)`,
we're getting `$cor1` back not both, which suggests the correlation is still
tied to the join. Infact, `FilterJoinRule` won't actually fire here. Could you
double-check the sources you referenced? Happy to walk through it together if
that helps.
