GRAIN & TIME
一行代表什么
- 业务粒度
- 每行代表“Daybreak 机制腿晋级评估”的一条记录；逻辑粒度由 eval_date × leg 共同确定。
- 时间口径
- 以 eval_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
eval_date- eval date 对应的日历日期。
leg- 用于确定该表业务粒度或默认顺序的 leg 字段。
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，该表不提供稳定 cursor，结果过大时必须缩小标的、日期或其他筛选。
- legacy_unverified 仅供审计，不能当作当前有效学习证据
MACHINE CONTRACT
筛选、排序与分页
- 默认排序
eval_date, leg- 唯一键
—- 读取模式
canonical_final_active- 最大时间窗
- 未单独限制
可用 filters
archetype→ archetype · stringearned_up→ earned_up · integerfeed_contract_enforced→ feed_contract_enforced · integerfeed_contract_version→ feed_contract_version · stringleg→ leg · stringpromoted→ promoted · integerPOINT IN TIME
可复现读取
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。
