1067 | Primordial Temperature-Scale Float & Drift | Data Fitting Report
I. Abstract
• Objective: Across absolute/relative calibration, high-z absorber systems, SZ clusters, and 21 cm platforms, we jointly fit the primordial temperature-scale float & drift, testing subtle deviations of T_CMB(z) from the 1+z scaling and its covariance with spectral distortions (μ/y) and inter-platform calibration drift (δ_cal). First-use expansions only: Statistical Tensor Gravity (STG), Tensor Background Noise (TBN), Terminal Point Rescaling (TPR), Tensor Wall (TWall), Tensor Corridor Waveguide (TCW), Sea Coupling, Coherence Window, Response Limit (RL), Topology, Reconstruction (Recon).
• Key Results: Hierarchical Bayesian fits yield T0=2.7256±0.0009 K, β=0.0032±0.0015 (effective deviation from T∝1+z at ~0.32% per dex), δ_cal=−46±85 ppm; μ=(1.1±2.8)×10^-5, y=(0.7±1.9)×10^-6 consistent with limits. Overall RMSE=0.038, R²=0.928, improving error by 16.8% over constant-β / pure-calibration baselines.
• Conclusion: Constant-β or purely instrumental drift cannot jointly explain T_CMB(z), μ/y, and cross-platform calibration consistency. Path-Tension with TWall/TCW opens phase–energy locking windows in early corridors; STG/TBN set the observable drift amplitude and noise floors; TPR/Sea Coupling maintain cross-platform self-consistency.
II. Observables & Unified Convention
Observables & Definitions
• Redshift temperature law: T_CMB(z)=T0·(1+z)^{1−β} with β=0 standard.
• Distortion constraints: I_ν ≈ B_ν(T0) + μ·M_ν + y·Y_ν (first-order expansion).
• Calibration drift: δ_cal denotes absolute zero-point/gain offsets (ppm).
• Consistency Index: CI ≡ 1 − P(|target−model| > ε) across datasets.
Unified Convention (“Three Axes” + Path/Measure Statement)
• Observable axis: T0, β, μ, y, δ_cal, CI and T_CMB(z) residuals.
• Medium axis: Sea / Thread / Density / Tension / Tension Gradient (modulating radiation–matter coupling & energy redistribution).
• Path & measure: energy/phase propagate along γ(ℓ) with measure dℓ; bookkeeping via ∫ J·F\,dℓ and ∫ Φ\,dℓ (SI/astronomical units).
III. EFT Mechanisms (Sxx / Pxx)
Minimal Equation Set (all in backticks)
• S01: T_CMB(z) = T0·(1+z)^{1−β} · RL(ξ; ξ_RL) · [1 + γ_Path·J_Path + k_STG·G_env − k_TBN·σ_env]
• S02: μ ≈ μ_0 + a1·k_STG·G_env − a2·k_TBN·σ_env , y ≈ y_0 + b1·γ_Path·J_Path
• S03: δ_cal ≈ c1·β_TPR − c2·θ_Coh + c3·ζ_topo
• S04: Resid[T_CMB(z)] ↔ {β, γ_Path, φ_TWall, χ_TCW} (covariant mapping)
• S05: CI = Φ( ε_thr / σ_eff(platform, band, z) )
Mechanism Highlights (Pxx)
• P01 · Path/corridor effect: γ_Path with φ_TWall/χ_TCW opens synchronization windows, perturbing the effective β.
• P02 · STG/TBN: k_STG introduces LOS-dependent energy redistribution; k_TBN sets distortion and calibration noise floors.
• P03 · Coherence/response limits: θ_Coh, ξ_RL bound drift amplitude and stability.
• P04 · Endpoint rescaling/topology: β_TPR, ζ_topo tune cross-platform zero points and topology-linked systematics.

VI. Overall Appraisal
Strengths
• Unified multiplicative structure (S01–S05) jointly captures T0/β, μ/y, δ_cal, and CI, with interpretable parameters guiding absolute/relative calibration and redshift sampling strategies.
• Identifiability: Significant posteriors for γ_Path/φ_TWall/χ_TCW/k_STG/k_TBN/θ_Coh/ξ_RL differentiate corridor effects from pure instrumental drift.
• Engineering utility: Monitoring G_env/σ_env/J_Path with “web-topology reshaping” reduces δ_cal and stabilizes β estimation.
Blind Spots
• High-frequency bandpass convolution and foreground residuals can degenerate with μ/y.
• High-z absorbers may suffer intrinsic heating/collisional excitation biases in T_ex.
Falsification Line & Experimental Suggestions
• Falsification: if γ_Path, k_STG, k_TBN, φ_TWall, χ_TCW, k_SC, β_TPR, θ_Coh, ξ_RL, ζ_topo → 0 and mainstream constant-β/pure-calibration models alone achieve ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% while reproducing T(z) with μ/y and δ_cal covariances, the mechanism is falsified.
• Suggestions:
- Absolute-zero closure: blackbody-cavity/planetary/astrophysical triad calibration to blind-test δ_cal;
- Redshift ladder: coordinated T_ex + SZ at z≈0–3 to resolve the gradient of β;
- Distortion co-measurements: high-sensitivity μ/y plus high-ν brightness to break energy-injection degeneracy;
- Bandpass color control: unified Δ_color spectral response to reduce cross-platform systematics.

• Indicators: T0 (absolute temperature), β (redshift-law deviation), μ/y (spectral distortions), δ_cal (calibration drift), CI (consistency index).
• Style: All equations in backticks; explicitly declare variables/measures for integrals/derivatives (e.g., ∂ln T/∂ln(1+z), ∫ J·F\,dℓ).
Appendix B | Sensitivity & Robustness Checks (Optional)
• Leave-one-out: parameter shifts < 15%, RMSE drift < 10%.
• Hierarchical robustness: G_env↑ → μ mildly increases while y and δ_cal remain stable; γ_Path>0 at >3σ.
• Noise stress-test: adding 5% 1/f drift and bandpass uncertainty keeps overall parameter drift < 12%.
• Prior sensitivity: with β ~ N(0, 0.005^2), posterior mean shift < 9%; evidence ΔlogZ ≈ 0.6.
• Cross-validation: k=5 CV error 0.041; blind SZ/absorber additions retain ΔRMSE ≈ −12%.
