// 钉钉 AI 表格（原多维表）同步服务 · 三表单粒度架构
// ----------------------------------------------------------------------------
// 双层架构的云端层：AI 表格 = 在线主档案 + 多人共享层；本地数据湖 = 计算缓存层。
// 云端按维度拆三张表（每张表内粒度唯一，AI/人工任意聚合都不会跨维度算重）：
//   · 门店明细（scope=shop）  · 连锁汇总（scope=chain）  · 公司汇总（scope=company）
//   · scope=summary 的区间汇总行不上云（可由门店行推导）
//   · pushLake — 把本地湖的新增/更新行（按 syncedAt 水位）分流 upsert 到三张表
//   · pullLake — 把三张表记录拉回本地湖（其他机器补数据用，云端为准）
// 业务键：日期|账号名|维度|连锁ID|门店ID（连锁ID 参与键：连锁/汇总行 shopId 为空，
// 缺它会互相覆盖）。与本地 rowKey（date|scope|chainId|shopId）语义对齐，幂等可重跑。
//
// 钉钉侧契约（企业内部应用 access_token，域 api.dingtalk.com；2026-10-17 真机核对）：
//   token:   POST /v1.0/oauth2/accessToken  {appKey, appSecret} → {accessToken, expireIn}
//   表清单:  GET  /v1.0/notable/bases/{baseId}/sheets?operatorId → {value:[{id,name}]}
//   建表:    POST /v1.0/notable/bases/{baseId}/sheets?operatorId  {name, columns:[{name,type}]}
//   建列:    POST …/sheets/{sheetIdOrName}/fields?operatorId  {name, type:'text'|'number'}
//   列清单:  GET  …/sheets/{sheetIdOrName}/fields?operatorId → {value:[{name,type,property}]}
//   列记录:  GET  …/records?operatorId&maxResults&nextToken → {records:[{id,fields}],nextToken,hasMore}
//   新增:    POST …/records {records:[{fields}]} → {value:[{id}]}（响应键是 value）
//   更新:    PUT  …/records {records:[{id,fields}]}（记录标识键是 id，不是 record_id）
//   删除:    POST …/records/delete {recordIds:[…]}（同步语义只 upsert，用不到）
//   · 所有 notable 接口 query 必带 operatorId=操作人 unionId（scripts/aitable-discover.js 发现）
//   · 数值字段读回是字符串（"12345.67"），recordToRow 已做 Number() 归一
//   · number 列 formatter=INT 只影响显示，存储小数保真
//   · 建表/建列接口有应用级限流（突发 ~5 次后 500 internalError，慢速补列即可），
//     记录读写接口不受影响；记录写入遇到不存在的字段名报 404 notFound
// ⚠ 批量上限（100）是保守值，首推大批量时如遇限流再调。
