Research direction
Investigate how Delta Kernel reads tables by examining existing unit tests in the 'kernel' module. Focus on the cloning feature, both shallow and deep clones, to understand expected behavior. Look for relevant test files in 'delta kernel/src/test' and review any documentation on table cloning.
