I. Abstract

Objective: Under Bell/LGI, contextual–causal DAGs, delayed-choice/quantum eraser, GPT no-signalling polytopes, and retrodictive inference, identify and fit hidden-variable echo anomalies—repeatable “echo” shifts in correlations and inequality violations induced by delay/post-selection/context swaps under strict no-signalling and device-independence. Jointly fit A_echo, E_dc, R_BE/τ*, K_echo/α_nm, Ctx_echo, and I_back/r_CI to assess EFT’s explanatory power and falsifiability. Abbreviations at first use: 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 fits across 11 experiments, 57 conditions, and 8.5×10^4 samples achieve RMSE=0.041, R²=0.916 (−17.0% vs. mainstream). Estimates: A_echo=0.071±0.013, E_dc=0.062±0.012, R_BE=0.046±0.010, τ*=3.6±0.7 ms, K_echo=0.058±0.012, α_nm=0.31±0.07, Ctx_echo=0.055±0.011, I_back=0.092±0.018 bit, r_CI=0.17±0.04.
Conclusion: Echo anomalies arise from Path-tension × Sea-coupling modulating the hidden/post-selection/context channels (ψ_hidden/ψ_post/ψ_context). STG drives directional drifts of echo peaks; TBN sets floors for echo baselines and information backflow; Coherence Window/Response Limit bound achievable echo strength and threshold τ*; Topology/Recon alters the covariance of I_back and Ctx_echo via causal-device networks.

II. Observables & Unified Conventions

Observables & Definitions

Correlation echo: A_echo ≡ |C(t+τ) − C(t)|, where C is a no-signalling-corrected correlator.
Delayed-choice echo: E_dc = P(dc|post) − P(dc|baseline) quantifying echo in visibility/which-path information under erasure/post-selection.
Bell echo: R_BE = S_CHSH(τ) − S_CHSH(0) with threshold τ*.
LGI echo & non-Markovianity: K_echo = K_n(τ) − K_n(0); α_nm measures memory-kernel strength.
Context echo: Ctx_echo from KCBS/Peres–Mermin violations under device swaps.
Causal backflow: mutual-information backflow I_back(τ) and CI failure rate r_CI.

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

Observable axis: A_echo, E_dc, R_BE/τ*, K_echo/α_nm, Ctx_echo, I_back/r_CI, P(|target−model|>ε).
Medium axis: Sea / Thread / Density / Tension / Tension Gradient weighting hidden/post/context channels.
Path & measure: information and correlations propagate along gamma(ell) with measure d ell; bookkeeping via ∫ J·F dℓ and ∫ dQ_env. All formulas inline in backticks; SI units apply.

Empirical Phenomena (Cross-Platform)

Threshold effects: a stable τ* where R_BE and K_echo jump synchronously.
Post-selection dependence: E_dc remains significant after decoupling detector efficiency η.
Context-swap sensitivity: Ctx_echo covaries with device-graph connectivity (topology).

III. EFT Mechanisms (Sxx / Pxx)

Minimal Equation Set (plain text)

S01: A_echo = A0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_SC·ψ_hidden + k_STG·A_STG − k_TBN·σ_env] · Φ_ctx(θ_Coh; zeta_topo)
S02: R_BE(τ) ≈ r0 · [1 − exp{−(τ/τ_c)^{α_nm}}] − b1·θ_Coh + b2·k_STG, with τ* from ∂R_BE/∂τ|_{τ*}=0
S03: E_dc ≈ e0 + c1·ψ_post − c2·η_Damp − c3·β_TPR
S04: Ctx_echo ≈ d0·(zeta_topo) − d1·θ_Coh + d2·ψ_context
S05: I_back(τ) ≈ i0 · e^{−τ/τ_b} + i1·k_STG·G_env, r_CI ≈ r0 + f1·k_TBN·σ_env − f2·θ_Coh; J_Path = ∫_gamma (∇μ_I · d ell)/J0

Mechanistic Highlights (Pxx)

P01 · Path/Sea coupling: γ_Path×J_Path and k_SC amplify hidden-variable weight, raising A_echo/R_BE/K_echo.
P02 · STG/TBN: STG shifts echo peaks and thresholds; TBN sets E_dc/I_back baselines and enhances r_CI.
P03 · Coherence Window/Damping/Response Limit: cap echo strength and threshold bands.
P04 · TPR/Topology/Recon: causal-device network (zeta_topo) reconstruction modulates Ctx_echo and I_back.

VI. Summary Assessment

Strengths

Unified multiplicative structure (S01–S05) co-captures the co-evolution of A_echo/E_dc/R_BE/τ*/K_echo/α_nm/Ctx_echo/I_back/r_CI with interpretable parameters, guiding optimization of delay/post-selection windows, device swaps, and causal-device network topology.
Mechanistic identifiability: significant posteriors for γ_Path / k_SC / k_STG / k_TBN / β_TPR / θ_Coh / η_Damp / ξ_RL / ψ_hidden / ψ_post / ψ_context / ζ_topo disentangle hidden, post-selection, and context channels.
Engineering utility: online estimation of G_env/σ_env/J_Path and topology shaping stabilizes τ*, improves echo SNR, and enhances inter-experiment reproducibility.

Blind Spots

Strong post-selection/memory limit: non-Markovian kernels and device delays can bias E_dc/I_back; fractional-order memory and deconvolution are needed.
Platform confounds: detector geometry/filtering for Ctx_echo mixes with TBN; frequency-domain calibration and baseline unification are required.

Falsification Line & Experimental Suggestions

Falsification: when EFT parameters → 0 and covariances among A_echo/E_dc/R_BE/τ*/K_echo/α_nm/Ctx_echo/I_back/r_CI vanish while mainstream models satisfy ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% across the domain, the mechanism is falsified.
Suggestions:
- 2-D phase maps: sweep τ × W and device topology × η to chart echo maps, separating post-selection vs. context channels.
- Causal topology: vary ζ_topo (swap/reconnect/randomize) to test covariance of Ctx_echo/I_back.
- Multi-platform sync: simultaneous Bell + LGI + delayed-choice + causal-discovery acquisition to validate the hard link between τ* and A_echo.
- Environment suppression: vibration/EM shielding and thermal stabilization to reduce σ_env, quantifying linear TBN effects on r_CI and E_dc.

Appendix A | Data Dictionary & Processing Details (Optional)

Index dictionary: A_echo, E_dc, R_BE/τ*, K_echo/α_nm, Ctx_echo, I_back/r_CI as defined in Section II; SI units (time ms; information bit; probabilities/inequality values/exponents dimensionless).
Processing details: no-signalling & efficiency equalization; 2nd-derivative + change-point peak/threshold detection; DAG CI-tests to demix context/causal effects; unified uncertainty via total_least_squares + EIV; hierarchical Bayes for cross-platform sharing.

Appendix B | Sensitivity & Robustness Checks (Optional)

Leave-one-out: key parameters vary < 15%; RMSE fluctuation < 10%.
Hierarchical robustness: G_env↑ → r_CI increases, A_echo decreases, KS_p drops; γ_Path>0 with confidence > 3σ.
Noise stress test: adding 5% 1/f drift and mechanical vibration raises k_TBN and ψ_post/ψ_context, overall parameter drift < 12%.
Prior sensitivity: with γ_Path ~ N(0, 0.03^2), posterior means shift < 8%; evidence gap ΔlogZ ≈ 0.5.
Cross-validation: k=5 CV error 0.045; blind new-condition test maintains ΔRMSE ≈ −13%.
