Caveats
No source-specific caveats are recorded.
Strong lensing H0 measurements probe a different redshift baseline (z ~ 0.5–0.9 for lenses and sources) than either Planck (z ~ 1100) or supernovae (z ~ 0.03), making systematic errors largely independent and lensing a critical cross-check of the tension's reality.
