Survival probability of a single planet in a binary system that initially hosted three planets, across various orbital configurations. Each panel corresponds to a specific value of the binary’s semimajor axis a_B, with the x- and y-axes showing the binary’s inclination i_B and eccentricity e_B, respectively. Shaded regions with crosses denote dynamically unstable configurations where no planets survive, while diagonal hatches indicate stable configurations in which all three initial planets remain bound throughout the simulation.
