主线 1: rns1-customer-coach-api + 04-miniapp-core-business 后端实施
  - 新增 GET /xcx/coaches/{id}/banner 轻量接口
  - performance/records 加 coach_id 参数 + view_board_coach 权限分流
  - coach/customer/performance/board/task 服务层重构
  - fdw_queries 结算单粒度聚合 + consumption_summary 视图统一
  - task_generator 回访宽限 72h + UPSERT 替代策略 + Step 5 保底清理
  - recall_detector settle_type=3 双重限制 + 门店级 resolved

主线 2: 小程序权限分流 + 新增 coach-service-records 管理者视角业绩明细页
  - perf-progress 共享模块去重 task-list/coach-detail 动画逻辑
  - isScattered 散客标记端到端
  - foodDetail/phoneFull/creator* 字段透传

主线 3: P19 指数回测框架 Phase 1+2
  - 3 个指数表 stat_date 日快照模式
  - 新增 DWS_INDEX_BACKFILL / DWS_TASK_SIMULATION 工具任务
  - task_engine 升级 HTTP 实时 + 推演回测双模式

主线 4: Core 维度层启用
  - 新增 CORE_DIM_SYNC 任务（DWD → core 4 维度表）
  - 修复 app 视图空查询问题

主线 5: member_project_tag 改为 LAST_30_VISITS 消费次数窗口

主线 6: 2 个迁移 SQL 已执行（stat_date + member_project_tag 新窗口）
  - schema 基线与 DDL 快照同步

主线 7: 开发机路径迁移 C:\NeoZQYY → C:\Project\NeoZQYY（约 95% 改动量）

附带: 新建运维脚本（churned_customer_report / simulate_historical_tasks /
      backfill_index_snapshots）+ tools/task-analysis/ 任务分析工具
