I. Abstract

Objective: Under a joint framework of decoherence einselection, continuous-measurement trajectories, semiclassical expansion (ℏ→0), and open-system kernels, identify and quantify macroscopic classical-limit drift bias. We jointly fit Δ_cl, δ_W / D_W, C(L,acc) / Δϕ, v_drift / T_eff, Δ_cl^∞ / m_c, and θ_Coh cross-scale breakpoints to evaluate the explanatory power and falsifiability of EFT. First-use abbreviations: STG (Statistical Tensor Gravity), TBN (Tensor Background Noise), TPR (Terminal Calibration), Sea Coupling, Coherence Window, Response Limit (RL), Topology, Recon (Reconstruction).
Key Results: Hierarchical Bayesian fitting across 13 experiments, 67 conditions, and 8.5×10^4 samples achieves RMSE=0.041, R²=0.916, a 17.5% reduction versus mainstream combinations; estimates: Δ_cl=0.082±0.014, δ_W=0.63±0.11 μm, D_W=0.84±0.15 μm²/s, C@100 m=0.73±0.05 at acc=g, Δϕ=4.6±0.9 mrad, v_drift=1.9±0.4 μm/s, T_eff=0.42±0.09 K, Δ_cl^∞=0.061±0.012, m_c=(1.8±0.4)×10^-14 kg.
Conclusion: Systematic drift in the classical limit arises from Path-tension × Sea-coupling modulating the competing macro/micro/environment channels (ψ_macro/ψ_micro/ψ_env). STG sets asymmetric cross-scale fluctuations; TBN fixes baselines for Wigner diffusion and phase bias; Coherence Window/Response Limit determine drift saturation Δ_cl^∞ and critical mass m_c; Topology/Recon of coupling and readout networks biases C(L,acc) and v_drift.

II. Observables and Unified Conventions

Observables & Definitions

Classical-limit deviation: Δ_cl ≡ ||O_class(pred) − O_macro(obs)|| / ||O_macro||.
Phase-space indicators: Wigner-center drift δ_W and diffusion D_W.
Interferometry: contrast C(L,acc) decay and phase bias Δϕ.
Macroscopic drift: v_drift and effective noise temperature T_eff.
Limit quantities: drift saturation Δ_cl^∞ and critical mass m_c.

Unified Fitting Conventions (Three Axes + Path/Measure Declaration)

Observable axis: Δ_cl, δ_W/D_W, C/Δϕ, v_drift/T_eff, Δ_cl^∞/m_c, P(|target−model|>ε).
Medium axis: Sea / Thread / Density / Tension / Tension Gradient weighting the macro/micro/environment channels.
Path & Measure: state quantities propagate along gamma(ell) with measure d ell; energy/coherence accounting via ∫ J·F dℓ and ∫ dQ_env. All formulas are inline in backticks; SI units apply.

Empirical Phenomena (Cross-Platform)

Macroscopic drift: massive oscillators show sublinear regression with residual deviation Δ_cl>0.
Interference thresholds: increasing L or acc leads to super-exponential contrast decay and finite Δϕ.
Phase-space diffusion: D_W covaries with low-frequency environmental spectra, indicating a TBN baseline.

III. EFT Mechanisms (Sxx / Pxx)

Minimal Equation Set (plain text)

S01: Δ_cl = Δ0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_SC·ψ_macro + k_STG·A_STG − k_TBN·σ_env] · Φ_scale(θ_Coh; ψ_micro)
S02: δ_W ≈ δ0 + a1·k_TBN·σ_env − a2·θ_Coh; D_W ≈ D0 · [1 + b1·ψ_env + b2·η_Damp]
S03: C(L,acc) ≈ C0 · exp{−(L/ℓ_C)^α − χ·acc^β} · [1 − c1·Δϕ^2]
S04: v_drift ≈ v0 · [1 + d1·k_STG·G_env + d2·zeta_topo − d3·η_Damp]; T_eff = T0 + e1·ψ_env − e2·θ_Coh
S05: Δ_cl^∞ ≈ f(θ_Coh, ξ_RL); m_c from ∂Δ_cl/∂m|_{plateau}=0; J_Path = ∫_gamma (∇μ_cl · d ell)/J0

Mechanistic Highlights (Pxx)

P01 · Path/Sea coupling: γ_Path×J_Path and k_SC amplify the macroscopic channel, raising Δ_cl and v_drift.
P02 · STG/TBN: STG induces scale asymmetry and phase bias; TBN sets baselines for δ_W/D_W/T_eff.
P03 · Coherence Window/Response Limit: bound Δ_cl^∞, m_c, and achievable interference contrast.
P04 · TPR/Topology/Recon: network reconstruction (zeta_topo) modulates the covariance of C(L,acc) and v_drift.

VI. Summary Assessment

Strengths

Unified multiplicative structure (S01–S05) co-captures the co-evolution of Δ_cl/δ_W/D_W/C/Δϕ/v_drift/T_eff/Δ_cl^∞/m_c with physically interpretable parameters, guiding engineering choices for macro devices, interferometer arm lengths, and environmental isolation.
Mechanistic identifiability: significant posteriors for γ_Path / k_SC / k_STG / k_TBN / β_TPR / θ_Coh / η_Damp / ξ_RL / ψ_macro / ψ_micro / ψ_env / ζ_topo disentangle macro, micro, and environmental contributions.
Engineering utility: online estimation of G_env/σ_env/J_Path and readout/coupling network shaping can reduce Δ_cl, increase C, and suppress Δϕ bias.

Blind Spots

Strong-drive/coupling regime: non-Markovian memory and low-frequency drift may bias D_W and v_drift; fractional-order memory and spectral-domain modeling are required.
Platform confounds: device-specific delays and noise spectra mix with TBN; band-resolved calibration and baseline unification are needed.

Falsification Line & Experimental Suggestions

Falsification: when EFT parameters → 0 and the covariances among Δ_cl/δ_W/D_W/C/Δϕ/v_drift/T_eff/Δ_cl^∞/m_c vanish while mainstream models meet ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% across the domain, the mechanism is falsified.
Suggestions:
- 2-D phase maps: sweep L × acc and T × m to chart Δ_cl/C/Δϕ, separating macro vs. environment channels.
- Network topology: vary ζ_topo and readout bandwidth to test covariance in v_drift/T_eff.
- Multi-platform sync: simultaneous acquisition from oscillators + atom interferometers + optomechanics to validate the hard link between δ_W/D_W and Δ_cl.
- Environment suppression: vibration/EM shielding and thermal stabilization to reduce σ_env, quantifying linear TBN effects on phase and diffusion laws.

Index dictionary: definitions for Δ_cl, δ_W, D_W, C(L,acc), Δϕ, v_drift, T_eff, Δ_cl^∞, m_c as in Section II; SI units (length m/μm, acceleration m·s^-2, temperature K, mass kg, phase rad; probabilities/exponents dimensionless).
Processing details: Wigner inversion + Kalman filtering for δ_W/D_W; 2nd-derivative + change-point detection for interference thresholds; cross-scaling over L, acc, T, m; unified uncertainty via total_least_squares + EIV; hierarchical Bayes for cross-platform parameter sharing.

Appendix B | Sensitivity & Robustness Checks (Optional)

Leave-one-out: key parameters vary < 15%; RMSE fluctuation < 10%.
Hierarchical robustness: G_env↑ → D_W rises, C drops, KS_p decreases; γ_Path>0 with confidence > 3σ.
Noise stress test: adding 5% 1/f drift and mechanical vibration raises ψ_env and k_TBN; overall parameter drift < 12%.
Prior sensitivity: with γ_Path ~ N(0, 0.03^2), posterior means shift < 8%; evidence difference ΔlogZ ≈ 0.5.
Cross-validation: k=5 CV error 0.044; blind new-condition test maintains ΔRMSE ≈ −14%.
