+/**
+ * poll-after-turn.test.mjs — TASK-343
+ *
+ * A turn is exactly when new events pile up: the person who typed while the
+ * adapter was running is already waiting by the time it finishes. The loop
+ * nonetheless slept a full poll interval after every turn before looking
+ * again, so that person paid the turn plus the interval.
+ *
+ * Carved out of TASK-289, which traded one interval of greeting latency to put
+ * a waiting mention first; this removes the interval it was trading.
+ *
+ * The rule is narrow on purpose: only a batch that actually spawned looks
+ * again at once. An idle poll, or a batch that spawned nothing, keeps the
+ * interval — otherwise the loop spins.
