Running it from the CLI

traced; --format selects text or json.
Reaching it in the IDE

What it needs
Optional. An index is not marked required, but the impact trace is read from whatever has been indexed, so a stale or missing index gives an incomplete answer.
Example
Illustrative only:
drag-lint impact --qname CustomerOrder.TCustomerOrder.Total --db C:\Projects\MyApp\_D-RAG\MyApp.sqlite --depth 3This would report what is affected, up to 3 levels out, if the Total
member of TCustomerOrder changes.
