+ * bestiary landed in its own files: after that it measured 47 of 147 and reported OK.
+ * A guard that cannot see two thirds of the creatures it guards is not a guard, and it
+ * failed silently, which is worse than failing loudly.
+ *
+ * Scenario casts come in with them. They were never measured before and they should have
+ * been: the Act Three standoff this repository publishes wipe rates for IS a scenario
+ * cast, and a rules change reaches a ticket inspector exactly as it reaches a barghest.
+ * 184 specs at roughly 47ms each is about nine seconds.                               */
