Implementation locked and ready.
Here is the complete, minimal, copy-paste runnable block that does exactly what you asked:

print("\nSaved: sweep_diagnostics_v_eff.csv and v_eff_cascade_summary.csv")
What to do now
1Paste your unchanged helper functions (smooth_periodic, halo_field, etc.) into the script above.
2Run it.
3Paste the printed table (or the content of v_eff_cascade_summary.csv) here.
I will then analyze whether the trends are monotonic as expected (rising coherence_drop, falling event_onset_sweep).
Contraction helper (standing by)
Once you post the results, here is the clean eff_radius version ready to drop in:
def get_effective_radius(cfg: SimConfig, v_eff: float, use_contraction: bool = True) -> int:
if not use_contraction:
return cfg.domain_radius
factor = max(0.1, 1.0 - 0.4 * v_eff**2) # safety floor
return max(1, int(round(cfg.domain_radius * factor)))
Call it inside the tidal block and use the returned value for the affected set.
Run the four cases and drop the metrics table when you have it.
