ref.instrumenton instrument_id用 instrument_id 补充证券代码、名称、市场、交易所和资产类型。
event.candidateon candidate_id用 candidate_id 查看候选产生时点、状态和策略上下文。
HOW TO QUERY SAFELY
先用 catalog 确认当前契约;可按 catalog 中列出的 filters 进一步缩小范围;单页最多 5000 行,响应有 has_more 时原样传回 next_cursor 继续分页。

该资产没有 PIT 契约。普通 rows 端点仍按当前公开读模式返回数据;不要把它表述成历史时点快照。
