  "abstract": "Low-threshold neutrino and dark-matter experiments constrain light mediators through different momentum transfers, targets, and coupling combinations. We examine scalar and vector interactions in coherent neutrino--nucleus scattering, neutrino--electron scattering, and dark-matter direct detection. Three representative interaction models are used to compare recoil spectra and coupling degeneracies. For $^{73}\\mathrm{Ge}$ and $^{131}\\mathrm{Xe}$, the nuclear-charge response matrix has a condition number of approximately 115, so two different targets may still leave nearly parallel blind directions. An analytic profile-likelihood calculation shows how spectral overlap and uncertainties in neutrino interactions affect dark-matter discovery sensitivity in the neutrino fog. We discuss the implications of measurements from COHERENT, CONUS+, LZ, XENONnT, and PandaX-4T and specify which theoretical inputs, detector responses, and statistical correlations are needed to combine their constraints. keyword : coherent elastic neutrino-nucleus scattering; light mediators; neutrino--electron scattering; dark matter direct detection; non-standard interactions; solar neutrinos; complementarity",
