Dynamical evolution of planetary embryos in a representative simulation of Scenario FIX. Each line corresponds to one embryo: gray lines show all embryos, while colored lines highlight those that survive until the end of the integration at ∼50 Myr. Panels display the semimajor axis (top left), eccentricity (top right), inclination (bottom left), and planetary mass (bottom right). The horizontal dashed blue line in the semimajor-axis panel marks the fixed inner disk edge at 0.01 au, which is applied only during the gas-disk phase (up to 10 Myr).
