## TASK 1: Execute ETL Full-Chain Data Consistency Black-Box Check

**STATUS**: in-progress

**USER QUERIES**: User's single request - Run `python scripts/ops/etl_consistency_check.py` and summarize findings

**DETAILS**:
- User requested execution of the ETL consistency check script which performs:
  - API JSON vs ODS field completeness and value sampling
  - ODS vs DWD mapping correctness and value transformation verification
  - DWD vs DWS/INDEX aggregation logic verification
- The script at `scripts/ops/etl_consistency_check.py` has been fully read and verified complete (1011 lines)
- The script connects to the database via `PG_DSN` in read-only mode
- Output goes to `ETL_REPORT_ROOT` (from `.env`)
- No code changes needed - this is a pure execution task
- The script was NOT yet executed - context limit was hit before running it

**NEXT STEPS**:
1. Run the script: `uv run python scripts/ops/etl_consistency_check.py` from the workspace root directory
2. Check the output report in `ETL_REPORT_ROOT` (path from `.env`)
3. Read the generated report and summarize key findings to the user
4. Report structure expected: ETL execution overview, API↔ODS consistency, ODS↔DWD consistency, DWD↔DWS consistency, anomaly summary

**FILEPATHS**:
- `scripts/ops/etl_consistency_check.py` - the main script to execute
- `.env` - contains PG_DSN, ETL_REPORT_ROOT, FETCH_ROOT, LOG_ROOT

**KEY CONTEXT FROM PREVIOUS REPORTS** (for interpreting results):
- Known bug: `DWS_RELATION_INDEX` fails due to `d.is_delete` should be `s.is_delete` in `relation_index_task.py` line 226
- 14 DWS tasks are registered but not yet run (will show as SKIP)
- ODS layer: 22/22 tasks typically succeed
- DWD layer: 20/20 tables have data
- DWS layer: only 9/32 tables have data
- Known mapping issues: `dwd.dim_member.update_time` missing ODS source, `dwd.dwd_member_balance_change.principal_change_amount` missing ODS source
- 2 DWD tables don't exist yet: `dwd.dwd_goods_stock_movement`, `dwd.dwd_goods_stock_summary`

**USER CORRECTIONS AND INSTRUCTIONS**:
- All responses must be in simplified Chinese (language-zh.md steering)
- Use `PG_DSN` (production database) in read-only mode, do NOT modify any data
- Testing environment rules apply: must load `.env` properly, never skip config
- Output paths must come from `.env` environment variables (export-paths.md steering)
- Script execution convention: run Python scripts via `uv run python` or `python`
- The workspace root is `C:\NeoZQYY` on Windows with cmd shell
- Four database connections available via MCP: `mcp_pg_etl` (production), `mcp_pg_etl_test` (test), `mcp_pg_app`, `mcp_pg_app_test`
- store_id: `2790685415443269`

**Files to read**:
- `scripts/ops/etl_consistency_check.py`
- `.env`

执行 ETL 全链路数据一致性黑盒检查，按以下步骤完成：

1. 运行 `python scripts/ops/etl_consistency_check.py`
2. 脚本会自动：
   a. 从 LOG_ROOT 找到最近一次成功的 ETL 日志，解析本次执行的任务列表
   b. 从 FETCH_ROOT 读取本次 ETL 落盘的 API JSON 文件
   c. 连接数据库（PG_DSN），对本次任务涉及的每张表逐字段比对：
      - API JSON vs ODS：字段完整性、值采样比对（随机 5 条记录的关键字段）
      - ODS vs DWD：字段映射正确性、值转换验证（采样比对）
      - DWD vs DWS/INDEX：聚合逻辑验证（行数、关键指标抽查）
   d. 输出 Markdown 报告到 ETL_REPORT_ROOT
3. 检查报告输出，汇总关键发现

报告结构：
- 1. ETL 执行概览（任务列表、成功/失败/跳过统计）
- 2. API↔ODS 数据一致性（逐表逐字段值比对）
- 3. ODS↔DWD 数据一致性（映射验证 + 值采样）
- 4. DWD↔DWS 数据一致性（聚合逻辑验证）
- 5. 异常汇总与建议

注意：使用正式库 PG_DSN 连接（只读模式），不修改任何数据。
2. <implicit-rules>## Implicit Rules
Focus on creating a new spec file or identifying an existing spec to update. 
If starting a new spec, create a requirements.md file in the .kiro/specs directory with clear user stories and acceptance criteria. 
If working with an existing spec, review the current requirements and suggest improvements if needed. 
Do not make direct code changes yet. First establish or review the spec file that will guide our implementation.</implicit-rules>
