best survival gain +0.99802 +/- 0.00315 overall; 95% CI from 4 sampled sanitized outputs shows that under broad mild catastrophes (radius 5, intensity 0.06, threshold 0.0) survival jumps from 0.00000 +/- 0.00000 with no bank to 1.00000 +/- 0.00000 with bank persistence 0.88, while mean occupancy rises from 0.08782 +/- 0.00287 to 0.74732 +/- 0.00285; under stronger but narrower shocks (intensity 0.12, radius 2), bank persistence 0.88 still yields survival 0.99500 +/- 0.00566 at threshold 0.45 and 0.95789 +/- 0.00900 at threshold 0.75, with occupancy gains of +0.59109 +/- 0.00512 and +0.43330 +/- 0.00306

The seed bank is acting as a true catastrophe-memory buffer rather than just adding a small demographic cushion. When disturbances are spatially broad, dispersal alone cannot outrun simultaneous losses, and the no-bank system nearly always collapses; dormant storage reverses that regime completely. The strongest rescue appears when immediate movement is allowed, implying that corridor flow and temporal storage are complementary rather than substitutable. The effect weakens but remains large at higher thresholds, which is consistent with delayed dispersal sacrificing recolonization speed after correlated shocks.
