  "abstract": "Long-period radio transients (LPTs) in white dwarf binaries require sufficiently tenuous plasma to sustain coherent radio emission, posing a challenge in systems with dense accretion flows. ASKAP J1745-5051 (J1745) combines LPT-like radio pulses recurring approximately every 82 min with magnetic accretion and X-ray modulation at a consistent period. We investigate this coexistence using a unified mass-loading framework for Roche-lobe overflow and a tenuous donor wind in the binary magnetic field. The dense stream supplies the accretion curtain and near-white-dwarf X-ray sources, while the tenuous wind feeds flux tubes of $(1-4)\\times10^7\\,{\\rm cm^{-3}}$, satisfying the local density requirement for electron-cyclotron maser emission. A fiducial geometry places the X-ray maximum near orbital phase $0.886$ and produces a radio-visibility window at phases $0.22-0.33$, consistent with the primary observed pulse window. Geometrical modulation and curtain absorption produce stronger soft-band than hard-band X-ray variability. Long-term phase-connected radio monitoring and simultaneous X-ray observations can test this interpretation through recurring radio phase changes and correlated changes in X-ray modulation. These results extend the proposed connection between detached binary LPTs and magnetic cataclysmic variables (mCVs). J1745 may represent an evolved mCV near the orbital-period minimum, suggesting that LPT-like activity can occur at a late accreting stage.",
