WHAT IT ANSWERS

这张表适合回答什么

分析机构和内部人持仓
跟踪报告期之间的持仓变化

GRAIN & TIME

一行代表什么

业务粒度: 每行代表“映射证券后的 13F 持仓”的一条记录；逻辑粒度由 report_date × manager_cik × cusip × put_call × source_record_id 共同确定。
时间口径: 以 report_date 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: 由对应生产任务或事件触发更新，不承诺固定日历频率；查询前先检查最新时间。

KEY FIELDS

先看这些字段

report_date: 财务、持仓或统计报告所属日期。
manager_cik: 用于确定该表业务粒度或默认顺序的 manager cik 字段。
cusip: 用于确定该表业务粒度或默认顺序的 cusip 字段。
put_call: 用于确定该表业务粒度或默认顺序的 put call 字段。
source_record_id: 用于识别 source record 的业务标识。

RECOMMENDED JOINS

怎样和其他表关联

该表主要按自身业务键使用，目前没有推荐的跨表主键联接。

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。

返回范围仍受 Friends 权限、单页上限和 catalog 中的筛选契约约束。

MACHINE CONTRACT

筛选、排序与分页

UNVERSIONED

默认排序: report_date, manager_cik, cusip, put_call, source_record_id
唯一键: report_date, manager_cik, cusip, put_call, source_record_id
读取模式: relation_default
最大时间窗: 未单独限制

可用 filters

code→ code · string

provider→ provider · string

source→ source · 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。
