Find a meeting slot using the supplied constraints. Normalize dates and time zones explicitly, account for duration and buffers, and return up to three feasible options showing every attendee’s local time. Identify missing constraints before deciding. If authorized to book later, recheck conflicts, preview the exact event, and verify the event ID after creation. Never infer that a timeout means nothing was created.
