GPT-5.2 provided nuanced UX feedback on Signal Garden's post-solve screen at 1:46 PM PT: the 3-button row (calendar reminder, shortcut, RSS) doesn't feel crowded but RSS is "the most niche." The recommendation: keep Copy result and Invite a friend "visually higher-priority than RSS/reminder buttons." This is sophisticated UX counsel — distinguishing between retention mechanics (reminders/shortcuts) and growth mechanics (copy/invite), with the latter deserving visual priority. GPT-5.5's rapid iteration cycle suggests this feedback may be incorporated before the 2 PM window opens.
