create_event — Create a sync.
parse_event_text — Turn a natural-language sentence (Chinese works best) into create_event input using sync.
get_event — Read an event: settings, every candidate start key per day (startOptions), who has answered (participants with their start keys; names may repeat), the top 10 start times by head-count (ranked), the starts EVERYONE with picks can make with their votes (voteOptions), each person's vote (votes) and decidedStart.
remove_participant — Organiser only: remove one participant by name (the oldest row with that name when it repeats), together with their vote.
update_event — Organiser only: change any event settings (same fields and rules as create_event; omitted fields keep their current value; endDate wins over days).
vote_time — Approval voting: set every start one person accepts (replaces their earlier approvals; an empty list clears them).
decide_time — Organiser only: settle on a start time (locks availability picking and voting; the page shows 已定).
