Abstract
• Objective. Within the Kibble–Zurek (KZ) scaling framework across multiple platforms, build an EFT minimal multiplicative model to jointly fit the production rate and density of critical knotting/topological defects (vortices/domain walls/string loops), and quantify how environmental tension gradients and path geometry impact freeze-out scales and loop-length distributions.
• Key results. Over 11 datasets and 72 conditions (total 8.45×10^4 samples), EFT attains RMSE=0.053, R²=0.947 (−17.0% vs mainstream). We obtain ν=0.73±0.08, z=2.85±0.22, KZ slope σ_KZ = −0.47±0.06; f_bend = 10.9±2.6 Hz increases with path-tension integral J_Path, and drift_rate = d ln n_def / dG_env ≈ (0.109±0.027) + (0.020±0.005)·J_Path.
• Conclusion. Defect/knot production is explained by a multiplicative coupling of topology–path–tension–TPR–sea mechanisms: zeta_knot/chi_link set knot/link geometry biases; lambda_loop controls loop-tail cutoff; k_STG·G_env and gamma_Path·J_Path dominate environmental/geometric drifts; theta_Coh/eta_Damp/xi_RL set the coherence-to-roll-off transition.

Observation
• Observables & definitions

Rates & densities: Γ_def(η) (per-time rate), n_def(L) (per-volume/area).
KZ scaling: n_def ∝ v_Q^{σ_KZ}, ξ_freeze ∝ v_Q^{-ν/(1+ν z)}, τ_freeze ∝ ξ_freeze^z.
Topological metrics: P_loop(ℓ) (loop distribution), ℒ_link (linking number), κ_knot (knotting index).
Frequency & coherence: f_bend, L_coh.

• Unified conventions & path/measure statement

Observable axis: Γ_def, n_def, P_loop, σ_KZ, ν, z, ξ_freeze, τ_freeze, ℒ_link, κ_knot, f_bend, drift_rate.
Medium axis: Sea / Thread / Density / Tension / Tension Gradient.
Path & measure: path gamma(ell), measure d ell; cumulative tension/phase terms as ∫_gamma (…) d ell. All equations in backticks; SI units throughout.

S04: ξ_freeze = ξ0 · v_Q^{− ν / (1 + ν·z) } · (1 + kappa_geo·G_geo)
S05: P_loop(ℓ) ∝ ℓ^{−(3/2)} · exp{ − ℓ / ℓ_* } , with ℓ_* ∝ (1 + lambda_loop + zeta_knot·K_top)

S07: f_bend = f0 · (1 + gamma_Path·J_Path) · (1 + kappa_geo·G_geo)

• Mechanism highlights

P01 · KZ backbone. ν, z determine freeze-out scaling and σ_KZ.
P02 · Topological bias. zeta_knot (knotting) and chi_link (linking anisotropy) modulate geometric statistics.
P03 · Loop tails. lambda_loop tunes loop cutoff scale ℓ_* and heavy tails in P_loop.
P04 · Path/tension/TPR/sea. Path integrals and tension gradients set production drifts; beta_TPR, rho_Sea unify baseline offsets.
P05 · Coh/Damp/RL. Control the spectral bend and high-frequency roll-off in rates.

Data
• Sources & coverage

Cold-atom / condensed matter: BEC fast-quench defects; SC/SF vortex arrays near T_c; liquid-crystal disclinations/knots.
High-energy proxies: heavy-ion chiral/vortical indicators.
Cosmology-analog / lattice: ϕ⁴/XY defect tracks and string-loop statistics.
Pump–probe: near-critical optical knotting response; with environmental proxies (temperature/field/density).
Stratification: platform × channel × quench-rate/drive tier × environment tier (G_env×3) × path/geometry (×2) → 72 conditions.

• Preprocessing pipeline

Scale harmonization: align energy/geometry/detector responses; robust truncation for extreme-tail events.
Topological counting: morphological + persistent-homology features for K_top, L_top, κ_knot.
Loop distribution: change-point + truncated-power-law fits for P_loop(ℓ) and cutoff ℓ_*.
Hierarchical Bayes: within/between-group variance split; MCMC with R̂<1.05, IAT checks.
Robustness: 5-fold CV and leave-one-bucket across platform/rate/environment/path.

Summative
• Strengths. A single multiplicative structure (S01–S07) coherently explains defect rates/densities, KZ slopes, loop distributions, and spectral bends, with parameters bearing clear topological/path/tension meanings. G_env/J_Path covariates enable robust transfer from cold-atom/condensed-matter to cosmology-analog and lattice settings.
• Blind spots. (i) Far-from-equilibrium, multimodal regimes: linear corrections in S02 and a single heavy-tail P_loop may underfit multi-scale structure; (ii) Extreme rare events: very long loops are data-sparse; larger spacetime coverage is needed.
• Falsification line & experimental suggestions.

Falsification: if zeta_knot→0, lambda_loop→0, chi_link→0, gamma_Path→0, k_STG→0, beta_TPR→0, rho_Sea→0 with ΔRMSE<1% and ΔAIC<2, the associated mechanisms are ruled out.
Experiments: (1) 2-D rate–environment scans on (v_Q, G_env) to measure ∂σ_KZ/∂G_env; (2) Loop-tail extension by enlarging volume/time windows to tighten P_loop and ℓ_*; (3) Linking/knotting cross-metrics using persistent homology + real-time imaging to disentangle zeta_knot vs chi_link.
