3–5 Apr 2026: σ*≈0.7333, γ≈0.2667, Planck modest positive, DESI frozen operator null. Off the Hubble footnote. Open scaffold, not claimed as a tension resolution.

A three-day Grok-loop sprint between the 27 Mar D_f sim and the 13 Apr H0DN proxy. It solved a coefficient-eliminated fixed-point instead of targeting D_f = 2.7387 first. This article takes it off the Hubble-tension footnote. It is not a Hubble-tension resolution and not Package 17 closure.

C (σ) (2 - σ) = K_{ent} (σ)^{2} σ

σ_{*} \approx 0.7333, η_{*} \approx 0.7563, D_{f} \approx 2.7333, γ \approx 0.2667

The quadratic RG phase now looks closed at current truncation. … Next phase is now explicit: add the minimal interaction and project the self-energy.

Empirical note from the same sprint: a frozen solved core was competitive with a damping-only Planck layer (aggressive reduced χ² ≈ 1.45; conservative ≈ 2.13). On a cleaner DESI observable-map reconstruction the frozen source+propagation operator stayed null / weak; a shared transient could help Planck and was rejected by DESI. The 30 Apr w(z) sketch and the 4 May Quintom thread reuse χ ≈ 0.2667 — this γ. Later 2026 packets freeze γ = 0.2613 = 3 − 2.7387, not 0.2667. Remaining gap named in-thread: microscopic amplitude / ρ=B identification.

In UQCF-GEM, redshift is not just expansion. It behaves more like a measure of coherence history.

Not claimed

The 5 Apr “coherence history” sentence is a method line from the same sprint as the freeze. It is not a DESI posterior and not a Hubble-tension resolution. The freeze itself (Planck modest+, DESI frozen-operator null) is the 4 Apr timeline event.

Quadratic RG core is a derivation scaffold with a named remaining gap. DESI null on the frozen operator is recorded. Not a Hubble-tension resolution and not Package 17 closure.

Not claimed

Hubble tension is not resolved by this sprint, the 27 Mar D_f sim, or the 13 Apr H0DN proxy.
