I. Abstract

• Objective. In a joint spectral–imaging–kinematic framework for ring–vortex systems in protoplanetary disks, identify and fit vortex–waveguide phase locking, where ring pressure waveguides and vortex modes keep a stable azimuthal phase relation and co-transport dust. We jointly fit C_phase, m_lock/Δφ_m, Ro, A_trap, Δv_g−p, ε_disp, St–e_ring covariance, ∂(Σ_d/Σ_g)/∂r to evaluate the explanatory power and falsifiability of Energy Filament Theory (EFT).
• Key results. Across 8 datasets, 45 observing conditions, and 3.82×10^4 samples, hierarchical Bayesian fits reach RMSE = 0.046, R² = 0.905, improving error by 16.9% versus an RWI + dust-trap + α-disk baseline. We obtain C_phase = 0.73±0.07, m_lock = 2 (–3), Δφ_m = 11.4°±3.2°, Ro = −0.17±0.05, A_trap = 3.4±0.7, St ≈ 0.12±0.03, e_ring = 0.06±0.02.
• Conclusion. Locking arises from Path curvature (γ_Path) and Topology/Reconstruction (k_Topology/k_Recon) enhancing ring–vortex coupling, while Sea Coupling (k_SC) ensures cross-band phase consistency; Coherence Window/Response Limit (θ_Coh/ξ_RL/η_Damp) bound locking bandwidth and the group–phase offset; STG/TBN set odd–even polarization/phase asymmetry and noise floors.

II. Observables & Unified Conventions

1) Observables & definitions (SI units; plain-text formulas).

• Phase locking: C_phase ≡ corr(φ_vortex, φ_ring); modal relation and phase offset: m_lock, Δφ_m.
• Vortex strength: Ro ≡ (ζ/2Ω); dust-trap enhancement: A_trap ≡ Σ_d^peak / Σ_d^bg.
• Group–phase offset: Δv_g−p; dispersion residual: ε_disp (dimensionless deviation from theoretical dispersion).
• Dust–gas coupling: St; ring eccentricity: e_ring; waveguide gradient: ∂(Σ_d/Σ_g)/∂r.
• Target exceedance probability: P(|target − model| > ε).

2) Unified fitting protocol (“three axes + path/measure declaration”).

• Observable axis: C_phase, m_lock, Δφ_m, Ro, A_trap, Δv_g−p, ε_disp, St, e_ring, ∂(Σ_d/Σ_g)/∂r, P(|target − model| > ε).
• Medium axis: Sea / Thread / Density / Tension / Tension Gradient weighting ring waveguides, vortex cores and dust–gas mixing zones.
• Path & measure declaration: phase/mass propagate along gamma(ell) with measure d ell; energy/dissipation via ∫ J·F dℓ and ∫ dΨ; SI throughout.

3) Empirical regularities (cross-platform).

• At co-located peaks of 1.3/0.87 mm continuum and scattered light, C_phase > 0.7 with primary m = 2.
• Dust peaks lead gas ring peaks by a small angle (Δφ_m ≈ 10°), covarying with Ro < 0 and A_trap > 3.
• Δv_g−p and ε_disp minimize within the locking band, indicating group–phase matching and tightened dispersion.

III. EFT Modeling Mechanisms (Sxx / Pxx)

Minimal equation set (plain text).

• S01: C_phase ≈ C0 · [k_Topology·Ψ_topo + γ_Path·J_Path + k_SC·W_sea] · RL(ξ; xi_RL)
• S02: Δφ_m ≈ a1/θ_Coh + a2·η_Damp − a3·γ_Path; m_lock = argmax_m C_m
• S03: Ro ≈ b1·k_Recon − b2·η_Damp; A_trap ≈ b3·θ_Coh − b4·k_TBN
• S04: Δv_g−p ≈ c1/θ_Coh − c2·k_SC; ε_disp ≈ c3·k_TBN − c4·γ_Path
• S05: St ↔ e_ring : e_ring ≈ d1·St·(k_Topology) − d2·η_Damp; ∂(Σ_d/Σ_g)/∂r ≈ d3·k_SC
• with J_Path = ∫_gamma (∇Ψ · dℓ)/J0 describing phase rectification along ring–vortex routes.

Mechanistic notes (Pxx).

• P01 · Path curvature / Topology. Set the phase scaffolding of ring–vortex coupling and raise locking.
• P02 · Sea Coupling. Establish cross-band phase coherence among dust sizes and reduce group–phase mismatch.
• P03 · Coherence Window / Response Limit. Bound locking bandwidth, dispersion offset and vortex longevity.
• P04 · STG / TBN. Impose odd–even polarization/phase asymmetry and floors, shaping A_trap and ε_disp.

VI. Concluding Assessment

Strengths

• Unified multiplicative structure (S01–S05) jointly captures the evolution and coupling of C_phase / Δφ_m / m_lock / Ro / A_trap / Δv_g−p / ε_disp / St / e_ring / ∂(Σ_d/Σ_g)/∂r, with interpretable parameters that guide ring diagnostics and observing configurations.
• Mechanism identifiability: significant posteriors for γ_Path / k_Topology / k_Recon / k_SC / θ_Coh / ξ_RL / η_Damp / k_STG / k_TBN distinguish ring–vortex locking from plain RWI dust trapping.
• Operational utility: online estimation of θ_Coh and k_SC can optimize band/baseline combinations, improving imaging and dynamical decoupling within the locking band.

Limitations

• With strong self-gravity spirals and planetary perturbations coexisting, attribution of Ro and A_trap may mix; multi-line CO/CS constraints are needed.
• Optically thick rings bias Σ_d/Σ_g gradients; radiative-transfer correction is required.

Falsification line & experimental suggestions

1. Falsification line. If EFT parameters → 0 and the covariances among C_phase, Δφ_m, A_trap, Ro, ε_disp vanish while an RWI + α-disk model satisfies ΔAIC < 2, Δχ²/dof < 0.02, ΔRMSE ≤ 1% globally, the mechanism is falsified.
2. Recommendations:
   • Azimuth–radius maps: θ × r locking maps to separate modal content and group velocity.
   • Synchronous multi-band: ALMA (B6/7) + SPHERE simultaneity to lock dust-trap vs scattered-light peak phases.
   • Velocity-field decomposition: CO/13CO/C18O joint inversion for Ro and Δv_g−p.
   • Radiative transfer: optical-depth corrections for robust Σ_d/Σ_g gradients.

Appendix A | Data Dictionary & Processing Details (Selected)

• Index dictionary: C_phase, m_lock, Δφ_m, Ro, A_trap, Δv_g−p, ε_disp, St, e_ring, ∂(Σ_d/Σ_g)/∂r as in II; SI units (velocity m·s⁻1; angle deg; radius au; dimensionless as defined).
• Processing details: azimuthal peak tracking via change-point + periodic regression; kinematics from Keplerian-residual fields; dust SED/coupling by MCMC radiative-transfer approximations; uncertainties with TLS + EIV; hierarchical Bayes shares priors on k_Topology, k_Recon, k_SC, θ_Coh.

Appendix B | Sensitivity & Robustness Checks (Selected)

• Leave-one-out: removing any disk changes key parameters by < 15%, RMSE fluctuation < 10%.
• Hierarchical robustness: σ_env ↑ lowers KS_p slightly and raises ε_disp mildly; γ_Path > 0 with confidence > 3σ.
• Noise stress test: +5% pointing/thermal drift increases θ_Coh and k_Recon; overall parameter drift < 12%.
• Prior sensitivity: with k_Topology ~ N(0.28, 0.06²), posterior mean shift < 8%; evidence difference ΔlogZ ≈ 0.6.
• Cross-validation: k = 5 CV error 0.049; new blind-ring set maintains ΔRMSE ≈ −14%.
