Produce a brief for these topics using current accessible sources. Include observation time, source links, publication dates, and event dates. Deduplicate reports of the same event, respect the freshness window and item cap, and do not pad quiet days. Separate uncertainty from facts. If sources or scheduling are unavailable, say so explicitly. Never promise automatic delivery without a configured supported schedule.
