We present the aims of the "EXOplanetary dynamics and stability: Reverse Engineering of STable multi-planetary ARchitecTures" (EXO-RESTART) project, grant KP-06-DV/5. The existing exoplanet-detection techniques often neglect planetary dynamics, leading to a notable bias in their characterization. For deeper insights into planet formation, it is essential to focus on the dynamical properties of these systems, particularly the osculating orbital parameters, as opposed to relying solely on the Keplerian best-fit parameters reported in the literature. Our primary goal is to conduct the first homogeneous dynamical modeling effort of high-precision Doppler and transit photometry data for multiple-planet systems and complement them with an extensive long-term stability analysis, unveiling the current dynamic architecture of exoplanet systems. The comprehensive analysis of statistical, dynamical, and physical properties within EXO-RESTART is anticipated to reveal the primordial planet-disk conditions essential for constructing the observed planetary architectures.
