+"""Can this harness do a day's work on a PC? A measured answer, task by task.
+
+Every task is something a person does without thinking, run against a real GTK
+desktop on a real X server with the real mouse, and checked against the
+**application's own record** of what happened - not against the agent's opinion of
+itself:
+
+    python evaluate_daily.py            # the whole suite
+    python evaluate_daily.py --only menu
+
+It prints a table, and writes the same table to preview/daily-usage.txt so the
+model card can quote it.
