> When processing an incoming microbatch, if ignore-null is enabled for the AutoCDC flow, a non-null version map is populated for every upsert row. Delete rows retain a null version map and are handled as row-wide authorship during later reconciliation.
> Per the version-map contract documented in `Scd1VersionMap`, the map contains authorship information for every non-key user-data leaf in the target-aligned row. This ticket stamps each upsert independently, using only that row’s values and sequencing value.
> This ticket does not reconcile microbatch version maps with existing auxiliary or target-table state, nor does it reconcile multiple microbatch rows targeting the same key.
