Ensemble-averaged accretion source fractions of EF, EC, OC, and CI material for Earth analogs (blue) and Mars analogs (red) across all qualifying systems. Dots show individual simulations, and error bars indicate the mean ±1σ. Earth analogs preferentially accrete reduced inner-disk components (EF-EC), whereas Mars analogs exhibit enhanced contributions from OC material; CI fractions remain minor in both cases.
