+## Launch prompt
+
+```
+Use the app launch tooling to create a new project called "wiggleverse-ecomm".
+
+Stand up the clean ecomm implementation fresh, superseding the R01-R07 reference
+prototype (renamed to wiggleverse-ecomm-prototype today). Operator chose: full
+repo set (code + content), truly-minimal greenfield skeletons, no deploy yet.
+
+```
+
+## Deferred decisions
+
+_Autonomous-mode low-confidence calls the driver made and would have
+liked operator input on. Appended as the session runs; surfaced at
+finalize. Empty if none._
