: SNTM_baseline_WEF_flux_dynamics_v1.csv—Baseline food–energy–water sectoral flux trajectories for Figs.  and (100 time steps across local, regional, and global scales). SNTM_shock_response_water_deficit_policy_v1.csv—Sectoral flux responses to sequential shocks for Fig.  (local food shock at t = 20, policy shift at t = 30, amplification shock at t = 40). SNTM_sustainability_index_timeseries_v1.csv—Long-term recovery dynamics and sustainability index trajectories for Fig. 

: SNTM_validation_MDB_2000_2020_v1.csv—Murray–Darling Basin empirical data (2000–2020) for model validation. SNTM_validation_metrics_MDB_v1.csv—Statistical validation metrics including R 2 values for water (0.807), energy (0.856), and food (0.685) sectors. All datasets follow tidy data principles with explicit variable naming, units documented in file headers, and simulation run identifiers. Python implementation code (Python 3.14, NumPy 1.26, SciPy 1.11, pandas 2.1, Matplotlib 3.8) including equation solvers and visualization scripts is available from the corresponding author upon reasonable request.

: SNTM_model_architecture_components_v1.csv—Framework structure and equation mappings (Eqs.  – ). SNTM_parameters_calibrated_values_v1.csv—Calibrated parameter values with uncertainty ranges (Table ).
