    "Heuristic multilayer Perlin-noise clouds form, dissipate and move linearly; the cloud model is not a climate model.",
    "The four percentages are internal cloud-control settings, not measured cloud fractions.",
    "The cloud model is integrated with the paper’s SGL image-recovery simulation. It directly samples the projected image plane without an explicit telescope, detector or sampling-instrument model.",
    "A 1-degree source-map grid is used as the closest proxy for aperture size; about 200 simulated measurement epochs, 2.5 hours apart, have about 120 projected-plane samples each across 500 hours (about 24,000 total). Some samples fall on unilluminated locations.",
    "About 5,700 reconstructed cells; pixels south of 45 degrees S are excluded for the chosen 45 degrees N vantage point."

  "limits": [
    "Cloud model is not a climate model or realistic Earth cloud climatology.",
    "The 1-degree source-grid proxy is not a modeled optical aperture, telescope, detector or instrument-sampling response.",
    "Only four internal cloud-cover settings are reported, and no uncertainty bars are supplied for this comparison.",
    "The results identify a surface-map reconstruction risk; they do not test or invalidate gravitational lensing physics and do not settle a complete mission feasibility study.",
    "The line simply connects four reported cases; it is not a continuous response law or interpolation model."
