THE TIMELINE / DATED RECORD
What happened, and when?
10documented events
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 The earlier system did infer a curve from event wording, which read subject matter as conduct, so it was withdrawn rather than patched.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.

No perception score published for this creator
The dated events below are documented and sourced, but nobody has researched how audiences actually reacted to them. Creators On Record will not put a number on that until the research exists, so this record shows what happened and stops there.
