+```task
+id: RBT-WP-0004-T12
+status: done
+priority: medium
+```

+Done 2026-09-29: after "All steps done." the run view offers three smileys and a comment
+(what felt strange or unclear, ideas to optimize). Stored in the run record (history kept,
+latest wins, secrets refused); `rtut feedback <pack.yaml>` lists the latest per run.
+Follow-up: fold feedback into the overview and use it to prioritize pack refinements.

 ## Acceptance Criteria
 
 - Bernd can complete the SSH tutorial pack in the UI without pasting outputs to an agent.
