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

---
## TASK 1: Full Production Integration Test (api_full, verify_only, custom window)

- **STATUS**: done
- **DETAILS**: ETL run `896b9647` completed successfully. 22 ODS tasks: 21 SUCC, 1 FAIL (`ODS_ASSISTANT_LEDGER` — known JSONB bug, fix already in code). `verify_only` mode only executes ODS fetch + verification, skips DWD/DWS/INDEX.
- **FILEPATHS**: `export/ETL-Connectors/feiqiu/REPORTS/etl_timing_20260220_091414.md`, `export/ETL-Connectors/feiqiu/REPORTS/consistency_report_20260220_091414.md`

## TASK 2: Fix consistency report issues (missing DWD fields + whitelist)

- **STATUS**: done
- **DETAILS**: `principal_change_amount` fix: Added FACT_MAPPINGS expression. `update_time` fix: Added `KNOWN_NO_SOURCE` whitelist in `consistency_checker.py`.
- **FILEPATHS**: `apps/etl/connectors/feiqiu/tasks/dwd/dwd_load_task.py`, `apps/etl/connectors/feiqiu/quality/consistency_checker.py`

## TASK 3: ODS_ASSISTANT_LEDGER JSONB fix

- **STATUS**: done
- **DETAILS**: `_mark_missing_as_deleted` in `ods_tasks.py` now detects ALL JSONB columns via `cols_info` udt_name and wraps dict/list values with `Json()`.
- **FILEPATHS**: `apps/etl/connectors/feiqiu/tasks/ods/ods_tasks.py`

## TASK 4-5: Explain ETL modes and data pipeline

- **STATUS**: done

## TASK 6: Remove `pipeline` parameter, rename to `flow` everywhere

- **STATUS**: done
- **KEY DECISIONS**: `--pipeline-flow` (data_source deprecated param) intentionally KEPT. `"pipeline.fetch_root"` and `"pipeline.ingest_source_dir"` are AppConfig keys — NOT renamed.

## TASK 7: New `full_window` processing mode

- **STATUS**: done
- **FILEPATHS**: `apps/etl/connectors/feiqiu/cli/main.py`, `apps/etl/connectors/feiqiu/orchestration/flow_runner.py`, `apps/etl/connectors/feiqiu/tasks/ods/ods_tasks.py`, `apps/backend/app/services/cli_builder.py`, `apps/backend/app/routers/tasks.py`, `apps/admin-web/src/pages/TaskConfig.tsx`

## TASK 8: Sync full_window changes to docs and admin console

- **STATUS**: done

## TASK 9: Web-admin front-end/back-end integration test with full_window mode

- **STATUS**: done
- **DETAILS**: ETL CLI run completed at 14:52:54 (log `703747ca8db84aa785405fc75ee388a2.log`, 426KB). Run parameters: `--flow api_full --processing-mode full_window --window-start "2025-11-01" --window-end "2026-02-20" --window-split-days 10 --force-full` with 41 tasks. Results:
  - 22 ODS tasks: ALL 22 SUCC (including ODS_ASSISTANT_LEDGER — JSONB fix worked)
  - DWD_LOAD_FROM_ODS: SUCC
  - DWS_BUILD_ORDER_SUMMARY: SUCC
  - DWS_WINBACK_INDEX: SUCC (62 rows)
  - DWS_NEWCONV_INDEX: SUCC (14 rows)
  - DWS_RELATION_INDEX: FAIL (`d.is_delete` column doesn't exist — SQL bug in `relation_index_task.py` line 226, should be `s.is_delete`)
  - 14 DWS tasks: SKIP (not registered in task registry)
  - No timing report or consistency report was auto-generated (FlowRunner's `full_window` goes through `INCREMENT_ETL` else branch but report generation may have failed silently)
- **FILEPATHS**: `export/ETL-Connectors/feiqiu/LOGS/703747ca8db84aa785405fc75ee388a2.log`

## TASK 10: Black-box integration test report (API input side vs DB output side)

- **STATUS**: in-progress
- **DETAILS**: Created and ran `scripts/ops/blackbox_test_report.py`. Report generated at `export/ETL-Connectors/feiqiu/REPORTS/blackbox_report_20260220_180744.md` (10KB). The report has 6 sections:
  1. ETL execution summary (25 SUCC, 1 FAIL, 14 SKIP)
  2. API input vs ODS output — all 22 ODS tasks show data, API fetched counts match expectations
  3. ODS → DWD row comparison — **MAJOR BUG**: Most DWD fact tables show `-1` rows because the `DWD_TO_ODS` mapping in the script uses wrong table names (`fact_payment`, `fact_settlement`, etc.) but actual DB tables are named `dwd_payment`, `dwd_settlement_head`, etc. Only dim tables (which happen to match) show correct data.
  4. DWD data quality (NULL rates) — works correctly, shows all 40 DWD tables with NULL analysis
  5. DWS sanity check — works correctly, shows 9/32 tables with data
  6. Conclusion — numbers are wrong due to the mapping bug

- **NEXT STEPS**:
  1. Fix `DWD_TO_ODS` mapping in `scripts/ops/blackbox_test_report.py` to use actual DWD table names from DB. The correct mapping (from DB query results) is:
     - `dwd.dim_assistant` → `ods.assistant_accounts_master` (correct already)
     - `dwd.dwd_assistant_service_log` → `ods.assistant_service_records` (was `fact_assistant_service`)
     - `dwd.dwd_assistant_trash_event` → `ods.assistant_cancellation_records` (was `fact_assistant_abolish`)
     - `dwd.dwd_payment` → `ods.payment_transactions` (was `fact_payment`)
     - `dwd.dwd_refund` → `ods.refund_transactions` (was `fact_refund`)
     - `dwd.dwd_settlement_head` → `ods.settlement_records` (was `fact_settlement`)
     - `dwd.dwd_table_fee_log` → `ods.table_fee_transactions` (was `fact_table_fee`)
     - `dwd.dwd_table_fee_adjust` → `ods.table_fee_discount_records` (was `fact_table_fee_discount`)
     - `dwd.dwd_platform_coupon_redemption` → `ods.platform_coupon_redemption_records` (was `fact_platform_coupon`)
     - `dwd.dwd_groupbuy_redemption` → `ods.group_buy_redemption_records` (was `fact_group_redemption`)
     - `dwd.dwd_member_balance_change` → `ods.member_balance_changes` (was `fact_member_balance_change`)
     - `dwd.dwd_recharge_order` → `ods.recharge_settlements` (was `fact_recharge_settlement`)
     - `dwd.dwd_store_goods_sale` → `ods.store_goods_sales_records` (was `fact_store_goods_sale`)
     - `dwd.dim_member_card_account` → `ods.member_stored_value_cards` (was `dim_member_card`)
     - `dwd.dim_groupbuy_package` → `ods.group_buy_packages` (was `dim_group_package`)
     - Also need to handle `_ex` tables (extended attribute tables) — they exist for most DWD tables
     - `fact_inventory_stock` and `fact_inventory_change` tables don't exist in DWD (ODS tables `goods_stock_summary` and `goods_stock_movements` also returned -1, likely don't exist)
  2. Re-run the script after fixing mappings
  3. Present the corrected report to the user
  4. Also note: `ODS_INVENTORY_STOCK` and `ODS_INVENTORY_CHANGE` ODS tables show `-1` rows — these tables may not exist in the DB schema, need to verify
  5. Consider also fixing the `compare_ods_dwd` function's ratio calculation for dim tables (SCD2 ratio can be very high, which is expected)

## Known Issues Found During Testing

- **DWS_RELATION_INDEX bug**: `relation_index_task.py` line 226 references `d.is_delete` but should be `s.is_delete`. File: `apps/etl/connectors/feiqiu/tasks/dws/index/relation_index_task.py`
- **14 DWS tasks not registered**: DWS_ASSISTANT_DAILY, DWS_ASSISTANT_MONTHLY, DWS_ASSISTANT_CUSTOMER, DWS_ASSISTANT_SALARY, DWS_ASSISTANT_FINANCE, DWS_MEMBER_CONSUMPTION, DWS_MEMBER_VISIT, DWS_FINANCE_DAILY, DWS_FINANCE_RECHARGE, DWS_FINANCE_INCOME_STRUCTURE, DWS_FINANCE_DISCOUNT_DETAIL, DWS_GOODS_STOCK_DAILY, DWS_GOODS_STOCK_WEEKLY, DWS_GOODS_STOCK_MONTHLY
- **FlowRunner timing/consistency reports not generated**: The `full_window` mode goes through the `else` branch (INCREMENT_ETL) in `flow_runner.py`, but no timing or consistency report files were created for this run

## KEY ARCHITECTURE

- Frontend: React + Vite + Ant Design at `apps/admin-web/` (port 5173, process ID 6 still running)
- Backend: FastAPI at `apps/backend/` (port 8000, started via `Start-Process` with `uv run uvicorn`)
- ETL: `apps/etl/connectors/feiqiu/`
- ODS PK = `(id, content_hash)` — snapshot mode, content change = new row
- DWD: dim tables use SCD2, fact tables use `fetched_at` window upsert. Actual table naming: dims = `dim_*`, facts = `dwd_*` (NOT `fact_*`)
- DWD extended attributes stored in separate `*_ex` tables
- DWS has no cursor; delete-before-insert by date range
- Four DB MCP connections: `mcp_pg_etl`, `mcp_pg_etl_test`, `mcp_pg_app`, `mcp_pg_app_test`
- `processing_mode` written to config via `build_cli_overrides()` so ODS tasks read via `self.config.get("run.processing_mode")`
- `full_window` mode: uses base window (CLI-specified or default 24h lookback), skips `_get_max_fetched_at` fallback, processes all layers, no verification

## USER CORRECTIONS AND INSTRUCTIONS

- All output text must be in simplified Chinese
- `fetched_at` is ETL ingestion timestamp, NOT business update time
- ODS content_hash change = NEW ROW (snapshot), not in-place update
- `--pipeline-flow` is a separate deprecated param (for data_source), should NOT be renamed
- Audit reminder pending for high-risk path changes
- Python scripts preferred over PowerShell for complex operations
- `test_audit_doc_alignment.py` has a pre-existing deadline flaky test — ignore it
- Backend must be started with `uv run uvicorn` (not plain `python -m uvicorn`)
- `controlPwshProcess` tool has trouble starting uvicorn — use `Start-Process` PowerShell command instead
- `getProcessOutput` buffer has limited capacity — for long-running ETL, check log files or DB directly
- API is the input side of the data pipeline (user explicitly confirmed)
- Use `mcp_filesystem_read_text_file` with `tail` parameter for reading log tails (more reliable than PowerShell `Get-Content -Tail` which gets truncated)

## Files to read

- `scripts/ops/blackbox_test_report.py` (the script that needs DWD_TO_ODS mapping fix — this is the active in-progress work)
- `export/ETL-Connectors/feiqiu/REPORTS/blackbox_report_20260220_180744.md` (current report with wrong DWD numbers)
- `apps/etl/connectors/feiqiu/quality/consistency_checker.py` (reference for correct table mappings and check patterns)
- `apps/etl/connectors/feiqiu/orchestration/flow_runner.py` (FlowRunner.run() to understand why timing report wasn't generated)
