+Design Doc 033: Dev Experiments
+###############################
+
+Summary
+=======
+
+This design document defines new ``taler://`` URIs to cause synthetic errors
+or special states in the wallet that can then be rendered by the UI.
+
+Motivation
+==========
+
+UIs need to handle various (error-) states and responses of wallet-core.  It's
+not easy to cover all of these states and responses manually.  Some of them are
+hard to reach or simulate without an elaborate test setup.
+
+Requirements
+============
+
+The implementation of synthetic errors should be as separate from production
+code as possible, to avoid making the normal code paths unreadable.
+
+
+Proposed Solution
+=================
+
+Special taler:// URIs
+---------------------
+
+* ``taler://dev-experiment/$STATE_ID``
+* ``taler://pay/...?dev-experiment=``
+
+Special http(s):// URIs
+-----------------------
+
+* ``http(s)://*.dev-experiment.taler.net/``
+ 
+  * URLs for this subdomain are handled specially by the
+    wallet's HTTP layer and return fixed / mocked responses
+    instead of making real requests.
