GRAIN & TIME

一行代表什么

业务粒度: 每行代表“KairoX 策略候选事件”的一条记录；逻辑粒度由 candidate_id × candidate_ts 共同确定。
时间口径: 以 candidate_ts 为主要查询时间轴；除下方限制特别说明外，时间戳按 UTC、日期按来源市场日历解释。
更新节奏: 由公告、新闻或业务事件触发更新，没有固定日历频率。

KEY FIELDS

先看这些字段

candidate_id: 策略候选标识；可联接 event.candidate 与 event.evidence_bundle。
candidate_ts: candidate ts 对应的时间戳；除表内特别说明外按 UTC 解释。

RECOMMENDED JOINS

怎样和其他表关联

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.source_documenton source_doc_id

用文档标识回溯标准化原文和来源信息；先核对两表字段口径。

HOW TO QUERY SAFELY

查询方法与已知限制

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。

字典采样时该关系可能为空；先查询 catalog 或小范围 rows 判断当前是否已有数据。

MACHINE CONTRACT

筛选、排序与分页

UNVERSIONED

默认排序: candidate_ts, strategy_lane, candidate_id
唯一键: —
读取模式: canonical_final_active
最大时间窗: 未单独限制

可用 filters

candidate_id→ candidate_id · string

entity_id→ entity_id · string

event_subtype→ event_subtype · string

event_type→ event_type · string

instrument_id→ instrument_id · integer

market→ market · string

source→ source · string

source_doc_id→ source_doc_id · string

source_event_id→ source_event_id · string

status→ status · string

strategy_lane→ strategy_lane · string

symbol→ symbol · string

POINT IN TIME

可复现读取

NOT AVAILABLE

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。

COPY-READY CALLS

怎么调用

同一数据集可用 HTTP、Python SDK、CLI 或 MCP；Key 始终只通过环境变量/Bearer Header 传递。

    print(page.data)
    if page.has_more:
        print("next cursor:", page.next_cursor)

CLI

friends-data get-dataset-rows event candidate --limit 100 --filter instrument_id=1
