      abstract     = {Identifying high-temperature unconventional charge order
                      and superconductivity in kagome systems is crucial for
                      understanding frustrated, correlated electrons and enabling
                      future quantum technologies. Here, we report that the kagome
                      superconductor YRu$_3$Si$_2$ hosts an exceptional interplay
                      of charge order, magnetism, and superconductivity, revealed
                      through a comprehensive suite of muon spin rotation (μSR),
                      magnetotransport, X-ray diffraction, and density functional
                      theory (DFT). We identify a high-temperature charge-ordered
                      state with propagation vector (1/2,0,0) and a record onset
                      temperature of 800 K, unprecedented in kagome systems and
                      quantum materials more broadly. μSR measurements further
                      reveal time-reversal symmetry-breaking below 25 K and
                      field-induced magnetism near 90 K, features mirrored in the
                      magnetoresistance, which reaches 45\% at low temperatures.
                      Band-structure calculations show two van Hove singularities
                      near the Fermi level, including one within a flat band. At
                      low temperatures, YRu$_3$Si$_2$ becomes superconducting
                      below Tc = 3.4 K with either two full isotropic gaps or an
                      anisotropic nodeless gap. These results establish
                      YRu$_3$Si$_2$ as a prime platform for studying correlated
                      kagome physics.},
