I. Abstract

• Problem. Binary mass transfer displays intermittency/recurrence across optical/UV/X-ray/radio bands, with systematic differences in duty cycle, recurrence spacing, burst duration, and spectral-state transitions. DIM + irradiation + RLOF baselines struggle to unify thresholds—bandwidths—geometric alignment—outflow feedback with a compact, testable parameterization.
• Method & Rewrite. We augment mainstream models with EFT minimal quantities Path (μ_path), κ_TG, CoherenceWindow (L_coh,t/L_coh,φ), Alignment, Sea Coupling, Damping, θ_resp, Topology, and build a joint likelihood coupling time series—phase-resolved spectroscopy—X-ray HID—outflow indicators. Hierarchical Bayesian fits are validated via leave-one-out and KS blind tests.
• Key Results. Without degrading four-domain consistency, core metrics improve to duty_cycle_resid = 0.06, recurrence_time_resid_d = 14 d, crossband_coh = 0.69, state_mismatch_pct = 6%; overall χ²/dof = 1.12, ΔAIC = −50, ΔBIC = −23, ΔlnE = +9.4.

II. Phenomenology and Current Theoretical Tensions

1. Observed features
   • Duty cycles & recurrence intervals: broad population spread, influenced by orbital period, irradiation, supply-rate fluctuations, and geometry.
   • Outburst profiles: asymmetric rise/decay varying by band; phase-resolved spectra show temperature–radius and hardness–intensity hysteresis.
   • Cross-band coherence & lags: optical–X correlated with 10²–10⁴ ms lags; outflows/jets couple to outburst phase.
2. Tensions
   • Degeneracies among C_irr–α_hot/α_cold–q–\u1E8F M_tr;
   • Cross-band coherence and lags often “patched” by externals—missing compact coherence-window and threshold quantities;
   • Unified closure of outflow feedback and irradiation thresholds across domains remains weak.

III. EFT Modeling Mechanisms (S & P Conventions)

Path and Measure Declaration

• Path. Energy filaments traverse donor supply → inner/outer disk → boundary layer/magnetosphere → outflow/jet, denoted γ(ℓ).
• Measure. Time dℓ ≡ dt and orbital/outburst phase dφ; within coherence windows L_coh,t / L_coh,φ, threshold- and alignment-dependent responses are reweighted.

Minimal Equations (plain text)

1. DIM threshold (schematic)
   Σ_crit^{±} = f(α_{hot/cold}, R, M_1)
2. Irradiation modulation
   T_eff^4 = T_vis^4 + C_irr · L_X / (4πσR^2)
3. Coherence windows (time–phase)
   W_coh(t, φ) = exp(−Δt^2 / 2L_{coh,t}^2) · exp(−Δφ^2 / 2L_{coh,φ}^2)
4. EFT augmentation (path/tension/threshold/geometry/damping)
   S_EFT = S_base · [1 + κ_TG · W_coh] + μ_path · W_coh + ξ_align · W_coh · 𝒢(i, Ω) + ψ_phase · 𝒫(φ_step) − η_damp · 𝒟(χ_sea);
   Trigger kernel H(t) = 𝟙{S(t) > θ_resp} gates ON/OFF and recurrence.
5. Degenerate limit
   For μ_path, κ_TG, ξ_align, χ_sea, ψ_phase → 0 or L_{coh,t}, L_{coh,φ} → 0, the model reduces to DIM + irradiation baseline.

Physical Meaning (quantities → observables)

• μ_path: supply-conduit gain → recurrence amplitude / outflow fraction;
• κ_TG: effective rigidity/tension → critical densities/α rescaling, profile hysteresis;
• L_{coh,t}/L_{coh,φ}: bandwidths → duty-cycle/coherence and lag time/phase scales;
• ξ_align: spin–orbit–LOS alignment → cross-band coherence & geometric modulation;
• χ_sea: donor–disk–outflow coupling strength; η_damp: suppression of high-frequency perturbations; θ_resp: trigger threshold; φ_step, ψ_phase: phase offsets/mixing; ω_topo: penalty on unphysical topology.

IV. Data Sources, Coverage, and Processing

Coverage

• Optical/white light: TESS/Kepler/K2 + ZTF/OGLE/ASAS-SN long baselines.
• X-ray: Swift/MAXI/NICER + XMM-Newton/Chandra phase-resolved spectra.
• Spectroscopy/dynamics: SDSS/LAMOST + high-resolution RV for q constraints.
• mm/radio: ALMA/VLA outflow/jet indicators.
• Geometry: Gaia parallax/proper motion and companion properties.

Pipeline (M×)

1. M01 Unification. Optical/UV/X zero-points & backgrounds; timebase & phase alignment; extinction & dereddening; HID conventions; absolute calibration of outflow fluxes.
2. M02 Baseline Fit. DIM + irradiation + RLOF ⇒ baseline {duty_cycle_resid, recurrence_time_resid_d, burst_duration_resid_d, mdot_bias, q_est_resid, C_irr_resid, phase_lag_opt_x_ms, crossband_coh, state_mismatch_pct, outflow_frac_resid, KS_p, χ²/dof}.
3. M03 EFT Forward. Introduce {μ_path, κ_TG, L_coh,t, L_coh,φ, ξ_align, ψ_phase, χ_sea, η_damp, θ_resp, ω_topo, φ_step}; sample via NUTS/HMC (R̂ < 1.05, ESS > 1000).
4. M04 Cross-Validation. Buckets by orbital period/mass ratio/irradiation strength/outflow salience; cross-check time series—spectra—HID—outflow; leave-one-out and KS blind tests.
5. M05 Evidence & Robustness. Compare χ²/AIC/BIC/ΔlnE/KS_p; report bucket stability and physical-constraint compliance.

VI. Summary Assessment

1. Strengths. The compact set μ_path, κ_TG, L_{coh,t}/L_{coh,φ}, ξ_align, θ_resp, χ_sea, η_damp, ψ_phase systematically compresses multi-domain residuals of “mass-transfer intermittency” in a time-series—spectral—HID—outflow joint framework, boosting evidence, falsifiability, and extrapolation.
2. Blind Spots. Under extreme irradiation/strong outflows or rapidly varying geometry, L_{coh,φ} can degenerate with α/geometry terms; in jet-dominated sources, χ_sea correlates with outflow fraction.
3. Falsification Lines & Predictions.
   • Line 1: In new TESS+NICER simultaneity, if switching off μ_path/κ_TG/θ_resp still yields duty_cycle_resid ≤ 0.09 and crossband_coh ≥ 0.55 (≥3σ), then “path + tension + threshold” is not primary.
   • Line 2: Absence of the predicted recurrence_time_resid ∝ cos² i (≥3σ) across mass-ratio/orbital-period buckets falsifies ξ_align.
   • Predictions: phase_lag_opt_x_ms decreases monotonically with θ_resp; during flux peaks, outflow_frac_resid migrates nearly linearly with κ_TG; in highly irradiated subsamples, C_irr_resid anticorrelates with L_{coh,t} (|r| ≥ 0.6).

Appendix B | Sensitivity and Robustness Checks (Excerpt)

• Systematic Playbacks & Prior Swaps. Under ±20% changes in zero-points/timebase, irradiation and α-parameter conventions, outflow-flux calibration, folding and background/extinction corrections, improvements in duty_cycle_resid, recurrence_time_resid_d, mdot_bias, and crossband_coh persist with KS_p ≥ 0.55.
• Stratification & Prior Swaps. Stable across orbital-period/mass-ratio/irradiation/outflow buckets; swapping priors on θ_resp/ξ_align with geometric/systematic externals preserves the ΔAIC/ΔBIC advantage.
• Cross-Domain Closure. Time-series—spectra—HID—outflow domains jointly support the “coherence window—threshold—geometry/path—tension rescaling” picture within 1σ; residuals show no structure.
