+## Launch prompt
+
+```
+Let's go through the process of trying to launch a new app using the engineering runbook. This is a test run - we'll tear it all down after we're done. Any ideas for what app we should fake build to first deploy it?
+
+[Session anchored in the ecomm working dir; began as an off-the-record runbook
+test, then the operator elevated it to a published transcript once the scope
+changed from a throwaway deploy test to scoping the launch-app skill suite.]
