   The fix itself is correct, but it introduces a **behavioral compatibility 
change**. Existing jobs may produce different source-to-sink table mappings 
after upgrading. From a user’s perspective, data may silently stop appearing in 
the previously mapped sink tables, which could look like silent data loss. We 
should carefully assess the affected scenarios and compatibility impact before 
merging this change.
