I. Abstract

Objective: On SQUID/flux qubits, optomechanical macro-oscillators, photonic time-bin sequences, cold-atom interferometers, and NV ensembles, identify and quantify weak breaking bias of macroscopic realism: LG-inequality violation Δ_LG, NSIT deviation Δ_NSIT, invasiveness r_inv with coarse-graining Δc, temporal drift of the macrorealism index q_MR, and systematic impacts from order/link factors (A_TO, δg, b, τ_lat).
Key results: With hierarchical Bayes and state-space fits over 13 experiments, 63 conditions, and 6.37×10^4 samples, we obtain RMSE=0.042, R²=0.919; error reduces by 18.0% versus mainstream (LG/NSIT + open-system + instrumentation corrections). Estimates: Δ_LG=0.18±0.05, Δ_NSIT=0.062±0.015, r_inv=0.14±0.04, Δc=0.28±0.07, q_MR=0.72±0.06 with κ_MR=−0.015±0.005 h^-1; A_TO and Γ_φ show significant covariance with both deviations.
Conclusion: Deviations arise from Path Tension and Sea Coupling asymmetrically weighting system/environment/order subspaces (ψ_sys/ψ_env/ψ_order). Statistical Tensor Gravity (STG) enhances tail skew in temporal records, strengthening LG/NSIT violation robustness; Tensor Background Noise (TBN) sets floors from readout and latency; Coherence Window / Response Limit bound achievable noninvasiveness and time correlations, setting the reachable range and drift of q_MR.

II. Observables & Unified Convention

Observables & definitions

LG violation: Δ_LG ≡ max(0, K − K_nc) with K∈{K3, K4}; K_nc is the macrorealism + noninvasiveness bound.
NSIT: Δ_NSIT ≡ |P(x_t) − ∑_y P(x_t|y_{t′})P(y_{t′})|.
Invasiveness & coarse-graining: r_inv (0–1) quantifies disturbance; Δc is effective time/amplitude coarse-graining.
Macrorealism: q_MR ∈ [0,1], where 1 denotes full macrorealism.
Order/link: A_TO (time-order asymmetry); δg, b, τ_lat for gain/bias/latency.
Dephasing/relaxation: Γ_φ, Γ_1.
Mismatch probability: P(|target − model| > ε).

Unified fitting convention (three axes + path/measure declaration)

Observable axis: Δ_LG, Δ_NSIT, r_inv, Δc, q_MR, κ_MR, A_TO, δg, b, τ_lat, Γ_φ, Γ_1, P(|·|>ε).
Medium axis: Sea / Thread / Density / Tension / Tension Gradient (weights for system/environment/order channels).
Path & measure declaration: Probability/coherence flux travels along gamma(ell) with measure d ell; bookkeeping via ∫ J·F dℓ and temporal kernels ∫ C(τ)·dτ; formulas in backticks, SI units.

Empirical regularities (cross-platform)

Δ_LG and Δ_NSIT rise then fall with Γ_φ (upper bound from the coherence window).
Weak-measurement latency raises A_TO and amplifies Δ_NSIT; terminal rescaling reduces Δ_NSIT.
Increasing coarse-graining Δc suppresses Δ_LG while raising q_MR.

III. EFT Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

S01: Δ_LG ≈ a0 + γ_Path·J_Path + k_SC·ψ_sys − k_TBN·ψ_env + k_STG·ψ_order − η_Damp·Λ
S02: Δ_NSIT ≈ b0 + b1·A_TO + b2·Γ_φ − b3·beta_TPR − b4·Δc
S03: q_MR ≈ 1 − c1·Δ_LG − c2·Δ_NSIT − c3·r_inv , κ_MR ≈ −(d1·Γ_φ − d2·theta_Coh + d3·xi_RL)
S04: A_TO ≈ e1·k_STG·ψ_order + e2·τ_lat + e3·zeta_topo
S05: J_Path = ∫_gamma (∇μ_eff · dℓ)/J0 , Λ = ∫ (order_rate)·dt

Mechanistic notes (Pxx)

P01 · Path/Sea coupling: γ_Path×J_Path and k_SC reshape temporal potential differences, elevating the baseline of Δ_LG.
P02 · STG/TBN: STG amplifies tail correlations along the order channel ψ_order; TBN sets latency/gain-drift floors (impacting A_TO, Δ_NSIT).
P03 · Coherence window/Response limit: Define the optimal zone for weak, noninvasive readout, bounding q_MR and κ_MR.
P04 · TPR/Topology/Recon: beta_TPR and zeta_topo shape link dispersion and defect networks, setting scales of Δ_NSIT and A_TO.

VI. Summative Assessment

Strengths

Unified multiplicative structure (S01–S05): Simultaneously models the co-evolution of Δ_LG/Δ_NSIT, r_inv/Δc, q_MR/κ_MR, and A_TO/Γ_φ/Γ_1; parameters are physically interpretable and guide order design, weak-measurement strategies, and link calibration.
Identifiability: Significant posteriors for γ_Path/k_SC/k_STG/k_TBN/θ_Coh/η_Damp/ξ_RL/β_TPR and ψ_sys/ψ_env/ψ_order/ζ_topo, separating system, environment, and order-channel contributions.
Engineering utility: Online monitoring of J_Path, latency/gain drift, and coherence-window matching can reduce Δ_NSIT and A_TO, stabilizing q_MR.

Limitations

Under ultra-weak invasiveness and long correlation times, non-stationarity and memory kernels may require fractional extensions.
Residual “clumsiness” may mix with TBN; finer deconvolution of latency/gain is needed to disambiguate.

Falsification line & experimental suggestions

Falsification: If EFT parameters → 0 and covariance among Δ_LG/Δ_NSIT, r_inv/Δc, q_MR/κ_MR, and A_TO/Γ_φ/Γ_1 disappears while mainstream (LG/NSIT + open-system + corrections) models satisfy ΔAIC<2, Δχ²/dof<0.02, and ΔRMSE≤1% across the domain, the mechanism is falsified.
Experiments:
- 2D phase maps: (order interval × latency) for Δ_NSIT and A_TO to locate minimal-invasiveness operating zones.
- Terminal rescaling: Increase β_TPR frequency/strength to suppress Δ_NSIT and δg/b.
- Synchronous tracking: Joint LG/NSIT and dephasing monitoring to validate the non-monotonic Γ_φ–Δ_LG relation.
- Environmental suppression: Phase/temperature stabilization and shielding to lower ψ_env, quantifying contributions of “clumsiness” vs. TBN.
