   <!-- Bito Reply -->
   The current implementation is designed to be defensive, prioritizing query 
correctness over aggressive pruning. When a partition mapping is active, the 
system evaluates the transform and appends the mirrored predicate. If the 
evaluation fails or returns unexpected results, the system defaults to skipping 
the mirroring entirely, which ensures that rows are not silently dropped due to 
mapping inaccuracies. This approach accepts a performance trade-off (scanning 
more partitions) to maintain data integrity, rather than attempting to preserve 
rows through complex logic that could introduce its own risks.
