  \caption{\textbf{Retention decay analysis for well-initialized cases.}
    Analysis is restricted to cases with $DSC \ge 0.7$ on the prompt frame.
    \textbf{(a)} Boxen plots showing the distribution of normalized decay slopes across prompting modes, where more negative values correspond to faster degradation in DSC as the object evolves over time.
    \textbf{(b)} Mean normalized decay slopes, summarizing the average retention behavior for each model and prompt type.
    \textbf{(c)} Cumulative distribution functions of the decay slopes, with annotated medians ($P_{50}$) highlighting that SAM~3 consistently exhibits less negative slopes than SAM~2.
