Preprocessing Workflow

  1. Deprojection and inclination unification; PSF corrections for V_rot and σ.
  2. PN/GC halo-velocity cleaning and outlier suppression, constructing σ_r/σ_t.
  3. Shape measurements (isovelocity/equipotential) to extract q(r) and Δψ(r); lensing–dynamics co-registration.
  4. Uncertainty propagation via total-least-squares + errors-in-variables.
  5. Hierarchical Bayesian MCMC layered by galaxy/radius/tracer/environment; convergence via R̂ and IAT; k=5 cross-validation.

VI. Summative Assessment

Strengths

  1. Unified multiplicative structure (S01–S05) captures the co-evolution of β_r/ΔM_J/q/Δψ/g_t with physically interpretable parameters, actionable for outer-halo dynamics, mass modeling, and lensing–dynamics consistency checks.
  2. Mechanism identifiability: significant posteriors across γ_Path, k_SC, k_STG, k_TBN, β_TPR, θ_Coh, η_Damp, ξ_RL, ζ_topo separate contributions from stellar, gas, and halo tracers.
  3. Operational utility: online monitoring of J_Path, σ_env, q(r) and g_t residuals enables early warning of Jeans mass bias and optimization of radii/tracer configuration.

Blind Spots

  1. Strong triaxiality and substructures (streams/shells) can yield multi-modal, non-stationary β_r.
  2. Low-surface-brightness halos make q(r) and Δψ sensitive to PSF wings and background systematics.

Falsification Line and Experimental Suggestions

  1. Falsification line. If EFT parameters → 0 and the covariance among β_r/ΔM_J/q/Δψ/g_t disappears while mainstream models achieve ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% globally, the mechanism set is falsified.
  2. Experiments.
    • Radius–anisotropy map: plot trajectories in (r/R_e, β_r) and overlay g_t residuals to localize turning radii.
    • Tracer cross-checks: joint PN/GC/stellar campaigns to isolate σ_env and measure linear k_TBN effects.
    • Shape–dynamics consistency: jointly fit q(r), Δψ(r) and β_r(r); scan Φ_topo to locate the turning radius.
