## TASK 1: 数据流结构分析 — 完整三阶段执行
**STATUS**: in-progress
**USER QUERIES**: 1 ("执行数据流结构分析，按以下步骤完成：第一阶段数据采集、第二阶段语义分析、第三阶段报告生成")
**DETAILS**:
### 第一阶段：数据采集 — DONE
- Ran `python scripts/ops/analyze_dataflow.py --limit 200` successfully
- 23 tables collected, all succeeded, 3405 total records
- Output to `C:\NeoZQYY\export\dataflow_analysis\` with subdirs: `json_trees/`, `db_schemas/`, `collection_manifest.json`
- DWD tables all returned 0 columns (DWD table names don't match ODS table names — DWD uses dimension/fact table names like `dim_member`, `dim_assistant`, not the ODS raw table names). This is expected behavior.
### 第二阶段：语义分析 — IN PROGRESS (data reading complete, analysis not started)
- **ALL 23 json_trees files have been read** into context — complete field structures for all tables
- **5 ODS schema files read**: `ods_settlement_records.json`, `ods_payment_transactions.json`, `ods_member_profiles.json`, `ods_assistant_accounts_master.json`, `ods_site_tables_master.json` — these contain DDL COMMENT annotations with field descriptions
- **Remaining 18 ODS schema files NOT yet read** — need to read them for complete mapping
- **DWD schema files all empty** (0 columns) due to table name mismatch
- **ETL loaders directory explored**: `apps/etl/pipelines/feiqiu/loaders/` has `ods/generic.py`, `dimensions/`, `facts/`, `base_loader.py`
- **ETL source code NOT yet read** — needed for understanding ODS→DWD mapping logic
### 第三阶段：报告生成 — NOT STARTED
- Need to generate final Markdown report with:
- Per-table: API source field tables, ODS tables, DWD tables
- JSON→ODS mapping (matched, payload-only, ignored fields)
- ODS→DWD mapping (direct, ETL-derived, SCD2 version control columns)
- Field coverage stats, type distribution, upstream/downstream mapping coverage
- Save to `SYSTEM_ANALYZE_ROOT` (`C:\NeoZQYY\export\dataflow_analysis\`) as `dataflow_YYYY-MM-DD_HHMMSS.md`
### Key Data Summary from collection_manifest.json:
| Table | Records | ODS Cols | DWD Cols |

### ODS Schema Pattern (from read files):
- Each ODS table has ETL metadata columns: `content_hash`, `source_file`, `source_endpoint`, `fetched_at`, `payload` (jsonb)
- ODS columns are lowercase versions of JSON camelCase fields (e.g., `settleList.balanceAmount` → `balanceamount`)
- Many tables store nested objects like `siteProfile` as jsonb or flatten the list-key fields only
- DDL COMMENTs follow pattern: `【说明】...【示例】...【JSON字段】...`
**NEXT STEPS**:
1. Read remaining ODS schema files (18 more) from `C:\NeoZQYY\export\dataflow_analysis\db_schemas\ods_*.json`
2. Read ETL source code for data flow understanding:
- `apps/etl/pipelines/feiqiu/loaders/ods/generic.py` (ODS loader)
- `apps/etl/pipelines/feiqiu/loaders/base_loader.py`
- `apps/etl/pipelines/feiqiu/scd/` directory (SCD2 logic for DWD)
- `apps/etl/pipelines/feiqiu/tasks/` directory (task definitions)
3. For each of the 23 tables, compute:
- JSON→ODS field mapping (semantic matching between camelCase JSON paths and lowercase ODS columns)
- Field purpose inference using DDL COMMENT + JSON samples + ETL code
- ODS→DWD mapping (requires reading DWD DDL files from `db/etl_feiqiu/schemas/` since runtime query returned empty)
4. Generate per-table statistics: field coverage rate, type distribution, mapping coverage
5. Assemble final Markdown report and save to `C:\NeoZQYY\export\dataflow_analysis\dataflow_2026-02-16_HHMMSS.md`
**FILEPATHS**:
- `scripts/ops/analyze_dataflow.py` — CLI entry point
- `scripts/ops/dataflow_analyzer.py` — core collection module with ODS_SPECS
- `C:\NeoZQYY\export\dataflow_analysis\collection_manifest.json` — collection results
- `C:\NeoZQYY\export\dataflow_analysis\json_trees\*.json` — 23 JSON tree files (all read)
- `C:\NeoZQYY\export\dataflow_analysis\db_schemas\ods_*.json` — 23 ODS schema files (5 read)
- `C:\NeoZQYY\export\dataflow_analysis\db_schemas\dwd_*.json` — 23 DWD schema files (all empty/0 cols)
- `apps/etl/pipelines/feiqiu/loaders/` — ETL loader code
- `apps/etl/pipelines/feiqiu/docs/architecture/data_flow.md` — architecture doc (read)
- `.kiro/specs/dataflow-structure-audit/tasks.md` — spec tasks (all completed)
**USER CORRECTIONS AND INSTRUCTIONS**:
- 当前仅分析飞球（feiqiu）连接器
- 报告使用中文
- Output to `SYSTEM_ANALYZE_ROOT` = `C:\NeoZQYY\export\dataflow_analysis`
- Filename format: `dataflow_YYYY-MM-DD_HHMMSS.md`
- DWD layer uses different table names (dim_member, dim_assistant, fact_* etc.) not the ODS raw table names — need to look at DDL files or ETL code to find the actual DWD table mappings
- The workspace steering rules require: Chinese output, UTF-8, audit for high-risk changes, Python scripts for complex ops
- This is a Kiro Hook-triggered analysis workflow (hook at `.kiro/hooks/dataflow-analyze.kiro.hook`)

执行数据流结构分析，按以下步骤完成：
第一阶段：数据采集
1. 运行 `python scripts/ops/analyze_dataflow.py` 完成数据采集（API JSON 原始数据 + DB 表结构查询）
2. 确认采集结果已落盘到 SYSTEM_ANALYZE_ROOT（或 docs/reports/）目录下的 api_samples/、json_trees/、db_schemas/ 子目录
第二阶段：语义分析
3. 读取采集结果中的 JSON 文件（json_trees/、db_schemas/、collection_manifest.json）
4. 读取 ETL 源码（apps/etl/pipelines/feiqiu/ 下的 loaders/、tasks/、models/、scd/ 等模块）理解数据流转逻辑
5. 为每个字段推断作用说明：优先使用 DDL COMMENT 注释，结合 ETL 源码映射关系和 JSON 数据样本综合判断
6. 计算 JSON → ODS 映射关系：基于字段语义匹配，标注已映射、仅存于 payload、被忽略的字段
7. 计算 ODS → DWD 映射关系：基于 ETL loader/task 源码理解数据流转，标注直接映射、ETL 派生、SCD2 版本控制列
第三阶段：报告生成
8. 编排统计总结：为每个表格生成有业务语义的字段统计（字段覆盖率、类型分布、上下游映射覆盖率）
9. 组装最终 Markdown 报告，包含 API 源字段表格、ODS 表格、DWD 表格及各自的统计总结
10. 将报告保存到 SYSTEM_ANALYZE_ROOT 目录，使用 dataflow_YYYY-MM-DD_HHMMSS.md 格式命名
11. 输出文件路径和关键统计摘要
注意：当前仅分析飞球（feiqiu）连接器。未来新增连接器时，应自动发现并纳入分析范围。
