Problem
buildCorrelatedSubQuery uses object equality to find the parent join-tree node. After reprocessing, alias objects are recreated, causing a toOne() failure.
Fix: Replaced object equality with name-based matching:
Before
filter(n|$n.alias==$newSourceAlias)->toOne()After
filter(n|$newSourceAlias.name->contains($[n.alias.name](http://n.alias.name/)))->toOne()Tests added:
testMilestonedMultiHopProjectionWithCrossJoin.pure— reproduces the crashtestAverageDerivedProperty.pure— validates derived property with concatenate + average
