+# Turnover-Controlled Ranking Stability
+
+If the E0->E1 reordering were purely a turnover effect, agents of
+similar turnover would not reorder. Within turnover terciles (binned by
+E1 turnover), the E0-vs-E1 Kendall tau remains low, so the reordering is
+not explained by turnover alone.
+
+| Regime | Turnover bin | Mean turnover | Within-bin tau (E0 vs E1) | Full-leaderboard tau |
+| --- | --- | ---: | ---: | ---: |
+| calm | T1 | 10.5 | 1.0 | 0.758 |
+| calm | T2 | 18.73 | 0.667 | 0.758 |
+| calm | T3 | 20.25 | 0.333 | 0.758 |
+| high_vol | T1 | 11.53 | 0.667 | 0.242 |
+| high_vol | T2 | 17.48 | 0.667 | 0.242 |
+| high_vol | T3 | 19.52 | 0.667 | 0.242 |
+| jump_tail | T1 | 11.43 | 0.667 | 0.455 |
+| jump_tail | T2 | 17.85 | 0.0 | 0.455 |
+| jump_tail | T3 | 19.75 | 1.0 | 0.455 |
+
+Mean within-bin tau across all regimes and terciles: **0.630** (vs.\ a full-leaderboard tau that is similarly low). The reordering persists within turnover strata.
