+//
+// Here we define the values using a macro BYPASS_EVENT_TYPE, so it can be
+// expanded differently in some places (for example, to automatically
+// map a bypass type value to its symbolic name). As such, new values must be
+// appended and cannot be inserted in the middle as there are instances where
+// we will load data between different builds.
+
+// Bypass due to explicit instruction for the current request.
+BYPASS_EVENT_TYPE(CURRENT, 0)
