Known gapsCopy Anchor Link

• No scheduled job announces automatically.
• A comment's "Your name" field is a free-form prefill, not an identity gate.
• Frozen daily winners sync to a signed-in user's account as the dailyBestCardAnnouncements collection — see Tool Data Sync — and the comment thread syncs too, through its own saved_daily_best_card_comments table (hooks/useDailyBestCardComments.ts) rather than that shared one. Both are still per-user, not a shared team resource.
