  "abstract": "We perform an ab initio quantum Monte Carlo calculation of the isospin-symmetry-breaking correction $δ_C$ to the superallowed $β$ decay of $^{10}{\\rm C}$. Using both phenomenological and chiral nuclear interactions, we evaluate the Fermi matrix element and quantify its deviation from the canonical $\\sqrt{2}$ value. The resulting $δ_C$ values lie in the range $\\approx 0.15$--$0.25\\%$ and are consistent, within sizable uncertainties (approximately $34\\%$--$65\\%$ relative), across Hamiltonians, indicating no statistically significant dependence on the choice of nuclear interaction. The extracted values of $V_{ud}$ are also found to be compatible with current determinations within these uncertainties.",
