CONTEXT TRANSFER: We are continuing a conversation that had gotten too long. Here is a summary:

---
## TASK 1: Execute Dataflow Structure Analysis (Two Phases)

**STATUS**: done
**USER QUERIES**: Initial request (from context transfer)
**DETAILS**: Completed in previous conversation. Ran `analyze_dataflow.py` and `gen_dataflow_report.py`. Output at `export/SYSTEM/REPORTS/dataflow_analysis/`.
**FILEPATHS**: `scripts/ops/analyze_dataflow.py`, `scripts/ops/gen_dataflow_report.py`

## TASK 2: Investigate Two Missing Field Mappings

**STATUS**: done
**USER QUERIES**: From context transfer + user follow-up asking to scan JSON values
**DETAILS**:
- `time_slot_sale` (store_goods_master): API returns it (all values = `'2'`, 692 records across 4 batches), but ODS DDL never had it
- `commoditycode` (tenant_goods_master): API JSON does NOT return `commoditycode` field (696 records all missing). API returns `commodity_code` instead (single string values like `'10000'`, `'10000028'`). All values are single-element (no multi-value arrays found). ODS has both `commodityCode TEXT` and `commodity_code TEXT` columns.
- One-off scan script `_scan_json_fields.py` was created and deleted
- JSON structure: `pages[].response.data.orderGoodsList` for store_goods, `pages[].response.data.tenantGoodsList` for tenant_goods
**FILEPATHS**: `scripts/ops/_scan_json_fields.py` (deleted)

## TASK 3: Add time_slot_sale + Merge commodity_code (Task 1 from user)

**STATUS**: in-progress
**USER QUERIES**: User's main request with two sub-tasks
**DETAILS**:

What was completed:
1. **Migration script created and executed on test DB** — all 3 ALTER TABLE operations succeeded:
   - `ods.store_goods_master` ADD `time_slot_sale INTEGER` ✓
   - `dwd.dim_store_goods_ex` ADD `time_slot_sale INTEGER` ✓
   - `dwd.dim_tenant_goods_ex.commodity_code_list` changed from `VARCHAR(256)` to `TEXT[]` ✓
   - Verification confirmed: ODS time_slot_sale=integer, DWD time_slot_sale=integer, commodity_code_list=ARRAY/_text

2. **DDL files updated**:
   - `db/etl_feiqiu/schemas/ods.sql`: Added `time_slot_sale INTEGER` to store_goods_master + COMMENT ✓
   - `db/etl_feiqiu/schemas/dwd.sql`: Added `time_slot_sale INTEGER` to dim_store_goods_ex + COMMENT ✓
   - `db/etl_feiqiu/schemas/dwd.sql`: Changed `commodity_code_list VARCHAR(256)` → `TEXT[]` ✓

3. **FACT_MAPPINGS updated** (partially):
   - `dwd.dim_store_goods_ex`: Added `("time_slot_sale", "time_slot_sale", None)` ✓
   - **NOT YET DONE**: `dwd.dim_tenant_goods_ex` commodity_code_list mapping needs update — currently maps from `commodity_code` (single value) but needs to map from `"commodityCode"` (the ODS column that stores the array format `["10000028"]`) and cast to TEXT[]

4. **Migration script file**: `db/etl_feiqiu/migrations/2026-02-21__add_time_slot_sale_merge_commodity_code.sql` ✓

5. **One-off migration runner**: `scripts/ops/_run_migration.py` still exists (needs cleanup)

**NEXT STEPS** (Task 1 remaining):
- Update FACT_MAPPINGS for `dwd.dim_tenant_goods_ex` — the `commodity_code_list` mapping currently reads `("commodity_code_list", "commodity_code", None)` but needs to be changed to map from `"commodityCode"` column and parse the JSON array `["10000028"]` into a PostgreSQL TEXT[] array. The mapping expression needs a cast like `"string_to_array(trim(both '[]' from \"commodityCode\"), ',')"` or similar approach using the ODS `commodityCode` column which stores `{10000028}` format
- The ODS loader is schema-aware (`_insert_records_schema_aware` in `ods_tasks.py` line 721) — it dynamically reads columns from DB, so no code change needed for ODS ingestion
- Clean up `scripts/ops/_run_migration.py`
- Update `docs/database/` with schema change documentation (db-docs.md rule)
- The `gen_field_review_doc.py` skip lists may need updating (lines ~908 and ~634) to reflect these fields are now mapped

**FILEPATHS**:
- `db/etl_feiqiu/migrations/2026-02-21__add_time_slot_sale_merge_commodity_code.sql`
- `db/etl_feiqiu/schemas/ods.sql`
- `db/etl_feiqiu/schemas/dwd.sql`
- `apps/etl/connectors/feiqiu/tasks/dwd/dwd_load_task.py` (FACT_MAPPINGS at ~line 113)
- `scripts/ops/_run_migration.py` (to delete)

## TASK 4: DDL vs Database Consistency Check + Migration Archive (Task 2 from user)

**STATUS**: not-started
**USER QUERIES**: User's second sub-task: "做完任务1后，检查主DDL+种子等，包含ODS DWD DWS INDEX。是否与当前数据库相同，若有遗失和偏差则合并，检查好后，将分支后续修改的DDL归档。"
**DETAILS**: Compare all DDL files (ODS, DWD, DWS, indexes) against actual test database schema. Find discrepancies, merge missing definitions, then archive branch migration scripts.
**NEXT STEPS**:
- Write a script to compare DDL files vs actual DB columns for all schemas (ods, dwd, dws)
- Check indexes match
- Check seeds
- Merge any discrepancies
- Archive migration scripts from this branch
**FILEPATHS**: `db/etl_feiqiu/schemas/ods.sql`, `db/etl_feiqiu/schemas/dwd.sql`, `db/etl_feiqiu/schemas/dws.sql`, `db/etl_feiqiu/schemas/` (index files), `db/etl_feiqiu/seeds/`, `db/etl_feiqiu/migrations/`

## USER CORRECTIONS AND INSTRUCTIONS:
- All output must go to `export/` directory structure via `.env` environment variables
- Scripts run from `scripts/ops/` — but cwd is currently stuck at `scripts/ops/` in the shell, so use absolute paths like `python C:\NeoZQYY\scripts\ops\script.py`
- Database testing uses `TEST_DB_DSN` (test_etl_feiqiu), never production
- All explanatory text in simplified Chinese
- Python scripts preferred over PowerShell for complex operations
- ODS loader is schema-aware — reads columns from DB dynamically, no hardcoded column lists needed
- Audit reminder is pending (root-file, dir:admin-web, dir:backend, dir:db, db-schema-change) — user will manually trigger `/audit`
- `db-docs.md` rule: any schema change must sync `docs/database/` with change description, compatibility notes, rollback strategy, and 3+ verification SQLs
- The locked `field_mappings/` directory in `export/SYSTEM/REPORTS/dataflow_analysis/` should be manually deleted after system restart (from previous task)

## Key Architecture Notes:
- ODS tables use `(id, content_hash)` as composite PK
- DWD dimension tables use SCD2 with `(pk, scd2_start_time)` as composite PK
- FACT_MAPPINGS in `dwd_load_task.py` format: `(dwd_column, ods_expression, cast_type)`
- ODS ingestion: `BaseOdsTask._insert_records_schema_aware()` dynamically reads table columns from DB — adding a column to DDL+DB is sufficient for ODS to start capturing it
- DWD loading: columns not in FACT_MAPPINGS are auto-mapped by matching column names between ODS and DWD

## Files to read
