+## Launch prompt
+
+```
+Follow-up fix for #8: F5 EDH still folderless because launch.json points it at the repo folder already open in the dev window (VS Code one-folder-one-window). Point the EDH at a committed sandbox/ playground subfolder instead; update README.
+
+```
+
+## 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._
