+// Controls CheatManager.CheckForDUIDMismatch, which returns true when the machine's stored device id
+// differs from the freshly-derived one. A true result sends the client down the migration path that
+// POSTs PlayerReporting/v1/deviceId and then stalls on Create Account.
+//
+// Three modes, chosen by config:
+//   Simulate = true  -> force TRUE  (fake a mismatch to reproduce the hang without a corrupt value)
+//   Suppress = true  -> force FALSE (the workaround fix: never migrate, never hang)
+//   both false       -> pass through, let the REAL check run against the actual stored value
+//                       (needed to observe a genuinely corrupt stored id, e.g. after Corrupt Stored DUID)
+//
+// Patch the concrete CheatManager method, NOT the abstract PGECJHKNIEN interface, or the prefix
+// never runs.
