+# verify.sh — Module 4 lab check.
+#
+# Exercises the `delete <index>` command the AI implemented across tasks.py and cli.py.
+# It adds three tasks, deletes the middle one by index, and confirms the right task is gone
+# and the other two remain. This is a behavior check on the multi-file change — it does not
+# care HOW the AI implemented it, only that `delete` works end to end.
+#
+# Run it from inside your tasks-app project directory:
+#     bash lab/verify.sh
+#
+# It saves and restores your real tasks.json, so your actual task list is left untouched.
