sprint-review

Sweep the running product at iteration close — the live surface, derived rather than listed, at more than one viewport and in every locale, and report what a reader would meet at a derived lower bound. Use when the drain reports its entry snapshot exhausted, or when the owner types it against an iteration worked by hand. It returns observations for the owner, never a verdict, and it gates nothing. It takes an optional iteration title as its argument, typed after its name; without one it uses the active iteration.
