+## Later-turn travel deals — 29 October 2026
+
+The publisher's base rulebook, printed p. 12, permits nonallied deals for
+future actions. The later-turn structured travel prototype does not reserve
+present resources or predict future funding. A known completion is protected;
+if the bounded search has no completion when the travel turn is actually
+closed, the term is provisionally voided. This is an online policy, not a
+publisher ruling or proof that every possible future contribution was searched.
