  "abstract": "High-power amplitude-modulated continuous-wave lunar laser ranging (AM-CW LLR) is a stochastic-gravitational-wave-background (SGWB) experiment that measures GW-driven drift and diffusion of the Earth--Moon orbit. Its observable is the coherent phase of a GHz modulation envelope returned by an individually resolved single hollow corner-cube retroreflector (HCCR), converted to absolute range and analyzed through its time-dependent mean and covariance. The response occurs at lunar orbital harmonics; the dominant low-eccentricity channel is centered at $f_2=0.847245\\,μ{\\rm Hz}$, and a five-year broadband forecast applies to spectra smooth over the resolution scale $T_{\\rm obs}^{-1}=6.34\\,$nHz about that resonance. A scalar 1-kW, 1064-nm link yields $5.893\\times10^3$ detected photons s$^{-1}$ and an $88.8$--$124.3\\,μ$m photon contribution in 100 s, while the forecasts adopt projected total range precisions of $80$ and $50\\,μ$m. In the covariance-dominated weak-signal regime, $Ω_{\\rm gw}^{95}\\proptoσ_R^2\\nuEff^{-1}T_{\\rm obs}^{-4}$. Using the published Earth--Moon response normalization, the five-year 95\\% thresholds are $1.86\\times10^{-7}\\Dtot$ for $80\\,μ$m and $500\\,{\\rm yr}^{-1}$ and $2.42\\times10^{-8}\\Dtot$ for $50\\,μ$m and $1500\\,{\\rm yr}^{-1}$, where $\\Dtot$ is the full-analysis threshold divided by the unit-factor response-anchored forecast. If end-to-end calibration, sampling, and marginalization give $\\Dtot\\le1.15$, the higher-performance campaign reaches nominal source-statistic equality for $Ω_{\\rm gw}=7.08\\times10^{-8}$ in five years. These measurable performance and information-retention requirements define high-power AM-CW LLR as a standalone quantitative SGWB experiment at the $0.85\\,μ{\\rm Hz}$ Earth--Moon resonance.",
