Which of the following scenarios does not warrant a False Start warning?

The scenario where the White Pivot is completely lined up in front of the Pivot Line does not warrant a False Start warning because it adheres to the placement rules governing the start of play in roller derby. When the pivots are correctly positioned, they are allowed to line up in accordance with the rules, as long as they do not breach the established boundaries or interfere with the opposing team's setup.

In this case, the key aspect is that the White Pivot’s position does not violate any rules regarding starting positions. The positioning of the pivots is crucial, and whether they are in front or behind the line can dictate the dynamics of the start without constituting a false start.

In contrast, the other scenarios involve actions that would typically lead to a False Start warning. For example, if the Jammer's skate rolls forward past the Jammer Line at the whistle, this constitutes a breach of the starting protocol, which is explicitly defined in the rules. Similarly, if the Red Pivot lines up behind White Blockers on the Pivot Line, it can imply improper positioning relative to the rules governing the engagement at the start, as it can disrupt the intended mechanics of the jam.
