Strongly lensed quasars with measured time delays provide a one-step distance and H₀ measurement, delivering few-percent precision and late-time H₀ values that sit near 73 km/s/Mpc (close to local-ladder results, in tension with Planck CMB at greater than 3σ) (Refsdal 1964; Suyu 2017; Wong 2020). Multiple independent lens systems agree on the high H₀ value, reinforcing the Hubble tension while raising concerns about mass-sheet degeneracies and unmodeled environment effects.
The standard model assumes all gravitational lensing convergence is sourced by the catalogued matter (lens galaxy plus line-of-sight structure plus environment). Time-delay lensing must therefore deliver the universal H₀ once mass-profile and environment systematics are controlled. Multiple lens systems converging on a high H₀ value beyond Planck has nowhere to go except as a real disagreement.
SCT replaces the hot-dense-center with a superluminal collision and the thermalized debris field. From this single change, the lensing potential acquires a coherent contribution from the parent-frame mesh that ΛCDM has no concept of. The effective gravitational potential is Φ_eff = Φ_local + Φ_mesh (P50, P51), where Φ_local is the catalogued matter and Φ_mesh is the constructive-superposition contribution from parent-frame embedding.
For galaxy-scale lenses in cluster environments, the coherent mesh contribution adds an effective amplification A ≈ 5 to 6 to the lensing mass (P52, with A* = 5.970 in fully virialized halos from Paper 13's zero-free-parameter derivation). ΛCDM lens models omit the mesh contribution, leading to overestimated time-delay distances D_Δt and overestimated H₀. The high H₀ values from H0LiCOW and TDCOSMO are therefore biased upward by the same coherent-mesh contribution that produces the A_lens = 1.18 CMB lensing excess (recid 16, recid 30) and the GGSL substructure excess.
Once the M6 mesh contribution is properly modeled, time-delay H₀ converges on the SCT/CAR consensus value 70.4 km/s/Mpc (Paper 16), the same intermediate value as TRGB and SCT-corrected Cepheids. The same coherent-mesh framework that flattens galaxy rotation curves without invoking a CDM particle (P54) explains the systematic offset between time-delay lensing H₀ and the cosmic-mean. There is no need for mass-sheet degeneracy explanations or unidentified environment effects.
If next-generation TDCOSMO analyses with full parent-frame mesh modeling deliver H₀ consistent with the local SH0ES value at the 0.5% level (no systematic downward shift after mesh correction), the M6 coherent-mesh-lensing explanation is refuted. Equivalently, if the predicted A ≈ 5 to 6 mesh amplification is found to be inconsistent with cluster baryon-fraction measurements at greater than 3σ, the M6 framework loses one parameter-free anchor.
