Conversation
The existing-target branch was reading `snapshot_meta_column_names` as the full source of column names, so a partial override (e.g. only `dbt_valid_to` + `dbt_valid_from`) dropped the other defaults and the next snapshot run failed with `KeyError: 'dbt_scd_id'`. Start from the defaults dict and merge in each provided override key.
