Simply Nailogical

Each marker is a dated, sourced event on a single timeline. The line stays flat because it is a spine, not a score: it rises and falls only where audience reaction has been separately researched. That research does not exist for this creator yet. The earlier system did infer a curve from event wording, which read subject matter as conduct, so it was withdrawn rather than patched. A flat line here means we have not published a measurement, not that nothing happened.
