+## Launch prompt
+
+```
+Fix cowriting.editSelection guard: accurate per-condition warnings (no editor / no selection / unsaved / outside-workspace) instead of one misleading "select some text" message, and make the workspace-membership check use a path-separator boundary (fix the startsWith prefix-collision latent bug). Reported during F7 manual testing: editSelection on a content-repo file (outside the EDH sandbox root) warned "highlight text" though text was selected.
+
+```
+
+## 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._
