## TASK 1: Execute Dataflow Structure Analysis (数据流结构分析)

**STATUS**: done

**USER QUERIES**: User query 1 ("执行数据流结构分析，按以下步骤完成")

**DETAILS**:
The user requested a two-phase dataflow structure analysis for the feiqiu (飞球) connector:

**Phase 1 - Data Collection**: Ran `analyze_dataflow.py` to collect API JSON samples, DB schemas, field mappings, and BD descriptions for all 23 ODS tables.

**Phase 2 - Report Generation**: Ran `gen_dataflow_report.py` to generate a comprehensive Markdown report with enhanced content (field diffs, coverage stats, business descriptions, sample values, cross-layer anchor links).

**Key challenge**: The shell's cwd was stuck at `C:\NeoZQYY\apps\etl\pipelines\feiqiu` and couldn't be changed (cd is forbidden). Both scripts require running from project root `C:\NeoZQYY` because they use relative paths for `.env` files and `TABLE_MAP` source parsing.

**Solution**: Created wrapper scripts (`scripts/ops/_run_dataflow.py` and `scripts/ops/_run_report.py`) that use `os.chdir(root)` to set the correct working directory before importing and calling the main functions.

**Results**:
- Phase 1: 23 tables all successful, 3405 total records collected
- Phase 2: Report generated at `export/dataflow_analysis/dataflow_2026-02-17_040043.md` (576.6 KB)
- All intermediate data landed in `export/dataflow_analysis/` subdirectories: `json_trees/`, `db_schemas/`, `field_mappings/`, `bd_descriptions/`, `collection_manifest.json`

**FILEPATHS**:
- `scripts/ops/analyze_dataflow.py` — CLI entry point for data collection
- `scripts/ops/dataflow_analyzer.py` — Core collection module (flatten_json_tree, collect_all_tables, dump_collection_results, build_field_mappings, parse_table_map, parse_fact_mappings)
- `scripts/ops/gen_dataflow_report.py` — Markdown report generator
- `scripts/ops/_run_dataflow.py` — Wrapper script for Phase 1 (created to solve cwd issue)
- `scripts/ops/_run_report.py` — Wrapper script for Phase 2 (created to solve cwd issue)
- `export/dataflow_analysis/dataflow_2026-02-17_040043.md` — Latest generated report
- `export/dataflow_analysis/collection_manifest.json` — Collection manifest

**NOTE**: The task is complete. The two temporary wrapper scripts (`_run_dataflow.py`, `_run_report.py`) were created as utility helpers and remain in the repo. No high-risk paths were modified, so no audit is required.

## CONTEXT: ODS Dedup Standardize Spec (Background)

**STATUS**: not directly relevant to current task, but provides important context

**DETAILS**: The workspace has an existing spec at `.kiro/specs/ods-dedup-standardize/` with tasks mostly completed (tasks 1-7 done, task 8 in-progress at subtasks 8.4-8.5, task 9 queued). This spec covers ODS dedup and soft-delete standardization. The dataflow analysis task was independent of this spec work.

**USER CORRECTIONS AND INSTRUCTIONS**:
- Shell cwd is `C:\NeoZQYY\apps\etl\pipelines\feiqiu` — cannot use `cd` command, must use absolute paths or wrapper scripts
- Scripts that need project root context should use `os.chdir()` in a wrapper
- Follow `tech.md` script execution rules: prefer Python scripts over complex PowerShell
- All output in simplified Chinese per `language-zh.md`
- This was a read-only analysis task (no code changes to high-risk paths), so no `/audit` needed

## Files to read
- `scripts/ops/_run_dataflow.py`
- `scripts/ops/_run_report.py`

USER QUERIES(most recent first):
1. <source-event>
    The user manually invoked this action
    The user is focued on the following file: No file focused
    The user has the following paths open: \apps\etl\pipelines\feiqiu\config\env_parser.py, \apps\etl\pipelines\feiqiu\config\env_parser.py
</source-event>

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
2. 确认采集结果已落盘，包括：
   - json_trees/（含 samples 多示例值）
   - db_schemas/
   - field_mappings/（三层映射 + 锚点）
   - bd_descriptions/（BD_manual 业务描述）
   - collection_manifest.json（含 json_field_count）

第二阶段：报告生成
3. 运行 `python scripts/ops/gen_dataflow_report.py` 生成 Markdown 报告
4. 报告包含以下增强内容：
   - 总览表含 API JSON 字段数列
   - 1.1 API↔ODS↔DWD 字段对比差异报告
   - 2.3 覆盖率表含业务描述列
   - API 源字段表含业务描述列 + 多示例值（枚举值解释）
   - ODS 表结构含业务描述列 + 上下游双向映射锚点链接
   - DWD 表结构含业务描述列 + ODS 来源锚点链接
5. 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。
