The previous logic mistakenly used > in both sides of a disjunction for TxIndex, which ignored cases where TxIndex was equal and Incarnation was higher. This led to stale composite versions and could cause spurious invalidations under parallel execution.
This aligns with VersionMap semantics and validation in execution/stagedsync/exec3_parallel.go, where correctness depends on treating (TxIndex, Incarnation) as the version identity/order.
