## TASK 1: Database DDL Audit and Consolidation

**STATUS**: done

**USER QUERIES**: 1 ("审查任务：查库现在数据库(测试数据库test_etl_feiqiu 和 test_zqyy_app)，以数据库现状为准，对db目录下的各个sql文件整合，输出一套最全的DDL")

**DETAILS**:
- Successfully queried both test databases (`test_etl_feiqiu` and `test_zqyy_app`) via MCP tools to extract all structural metadata
- Created a Python script `scripts/ops/gen_consolidated_ddl.py` that connects to both databases and generates the consolidated DDL
- Script uses `TEST_DB_DSN` and `TEST_APP_DB_DSN` from `.env` (with fallback to `PG_DSN` / `APP_DB_DSN`)
- Successfully ran the script, generating `docs/database/consolidated_ddl.sql` (176 KB / 4312 lines)
- Verified file completeness: 114 tables, 38 sequences, 247 indexes, 162 constraints, 8 views, 8 materialized views, FDW config included
- File structure: etl_feiqiu (6 schemas: meta/ods/dwd/core/dws/app) → zqyy_app (public schema) → FDW mapping
- The `app` schema in etl_feiqiu has NO tables, only 7 views (confirmed)
- FDW setup from `db/fdw/setup_fdw.sql` is appended at the end
- A temporary `_verify_ddl.py` was created and deleted after verification
- The earlier incomplete DDL file at `docs/database/consolidated_ddl.sql` was overwritten by the script run

**Database counts confirmed**:
- `test_etl_feiqiu`: meta (3 tables), ods (21 tables), dwd (40 tables), core (7 tables), dws (31 tables), app (0 tables, 7 views)
- `test_zqyy_app`: public (12 tables)
- dws schema also has: 1 view (v_member_recall_priority), 8 materialized views (mv_dws_assistant_daily_detail_l1-l4, mv_dws_finance_daily_summary_l1-l4)

**FILEPATHS**:
- `scripts/ops/gen_consolidated_ddl.py` — generation script (complete, working)
- `docs/database/consolidated_ddl.sql` — output DDL file (176 KB, complete)
- `db/fdw/setup_fdw.sql` — FDW reference (read, included in output)
- `db/README.md` — reference (read)

**NOTE**: This change touches `docs/database/` which is in the audit scope per governance rules. The user was reminded they can trigger `/audit` when ready.

**USER CORRECTIONS AND INSTRUCTIONS**:
- 以数据库现状为准 (database reality takes precedence over SQL files)
- Output is a single complete DDL set for production migration reference
- Language: Chinese for documentation/comments, English for code identifiers
- NOT NULL constraints should be inline in CREATE TABLE, not listed separately
- MCP tools: `mcp_pg_etl_test_execute_sql` (for test_etl_feiqiu) and `mcp_pg_app_test_execute_sql` (for test_zqyy_app)
- `docs/database/consolidated_ddl.sql` is project documentation (DDL baseline), NOT runtime output — so it correctly lives in `docs/` not `export/`
- Steering rules: export-paths.md applies to runtime outputs only; testing-env.md requires loading `.env` properly; governance.md requires audit for database-related changes
- Script execution: prefer Python scripts over complex PowerShell (per tech.md)
- Database connections must use test databases via `TEST_DB_DSN` / `TEST_APP_DB_DSN` environment variables

Files to read:
- `scripts/ops/gen_consolidated_ddl.py`
- `docs/database/consolidated_ddl.sql`
