Review Comment:
non blocking test issue: `value` is also the key, but graph resolution
rejects key columns in an ignore-null selection. Because `buildAutoCdcFlow`
does not resolve the graph, this test passes with an unusable configuration.
Could we use a non-key payload column and resolve or execute the graph?
