+### 30.31 Strategy skip eligibility
+
+The strategy-selection page only enables skipping while another unpicked player remains. The published order
+keeps finished players for display, so its total length cannot establish that a skip has a recipient. The client
+counts order entries absent from `draft.picks`, alongside the existing turn and quota checks. The server's
+`skipBand` already rejects the final player with `BAD_TARGET / nobody to pass to`; its rule remains unchanged.
+Regression covers normal two-, three- and four-human browser flows, the final turn, and exhausted quota.
