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

---
## TASK 1: Unified Export Directory Structure & .env Configuration
- **STATUS**: done
- **USER QUERIES**: 1-12 (from previous sessions)
- **DETAILS**: Created unified `export/` directory structure with three top-level categories: `ETL-Connectors/`, `SYSTEM/`, `BACKEND/`. Updated `.env`, `.env.template`, and `apps/etl/connectors/feiqiu/.env` with all path variables.
- **FILEPATHS**: `.env`, `.env.template`, `apps/etl/connectors/feiqiu/.env`

## TASK 2: Update LAUNCH-CHECKLIST.md & Create EXPORT-PATHS.md
- **STATUS**: done
- **DETAILS**: Updated deployment docs and created `docs/deployment/EXPORT-PATHS.md` with directory overview, env variable mapping, code adaptation status.
- **FILEPATHS**: `docs/deployment/LAUNCH-CHECKLIST.md`, `docs/deployment/EXPORT-PATHS.md`

## TASK 3: Eliminate ALL hardcoded output paths — use .env exclusively
- **STATUS**: done
- **DETAILS**: Across 4 sessions, all hardcoded output paths in `scripts/ops/`, ETL core modules, ETL scripts, and `config/defaults.py` were replaced with `.env` reads. Final scan confirms zero remaining `"docs/reports"` or `"export/..."` hardcoded output paths.

### Key changes completed:
- Created `scripts/ops/_env_paths.py` — shared utility with `get_output_path(env_var)`
- Updated all `scripts/ops/` scripts to use `_env_paths.get_output_path()`
- Updated ETL core modules (`quality/integrity_service.py`, `quality/integrity_checker.py`, `tasks/dwd/dwd_quality_task.py`) to raise on missing env
- Updated all ETL internal scripts (`scripts/check/`, `scripts/repair/`, `scripts/debug/`, `scripts/`) to use `ETL_REPORT_ROOT` env var
- Cleared `config/defaults.py` io paths to `""` (empty string)
- Fixed `api/recording_client.py` — removed `or "export/JSON"` fallback
- Created steering rule `.kiro/steering/export-paths.md`
- Restored `scripts/ops/dataflow_analyzer.py` from git history (was accidentally deleted in commit `4eac07da`), fixed its `output_dir` default from `"docs/reports"` to `""`
- Fixed `scripts/ops/gen_full_dataflow_doc.py` stale comment
- Updated `docs/deployment/EXPORT-PATHS.md` — defaults.py descriptions, removed fallback path references in sections 6/7, updated config priority section

### Test results:
- Property tests (`tests/test_dataflow_analyzer.py`): **89 passed** ✓
- ETL unit tests: **172 passed, 1 skipped, 1 failed** (pre-existing bug in `test_cli_args.py::test_data_source_online_sets_run_key` — `AttributeError: 'Namespace' object has no attribute 'force_full'`)

- **FILEPATHS**: `scripts/ops/_env_paths.py`, `scripts/ops/analyze_dataflow.py`, `scripts/ops/dataflow_analyzer.py`, `scripts/ops/gen_full_dataflow_doc.py`, `scripts/ops/gen_dataflow_report.py`, `scripts/ops/gen_dataflow_doc.py`, `scripts/ops/gen_api_field_mapping.py`, `scripts/ops/gen_full_dataflow_doc.py`, `scripts/ops/field_audit.py`, `scripts/ops/export_dwd_field_review.py`, `apps/etl/connectors/feiqiu/quality/integrity_service.py`, `apps/etl/connectors/feiqiu/quality/integrity_checker.py`, `apps/etl/connectors/feiqiu/tasks/dwd/dwd_quality_task.py`, `apps/etl/connectors/feiqiu/config/defaults.py`, `apps/etl/connectors/feiqiu/api/recording_client.py`, `apps/etl/connectors/feiqiu/scripts/debug/generate_report.py`, `apps/etl/connectors/feiqiu/scripts/debug/analyze_performance.py`, `apps/etl/connectors/feiqiu/scripts/debug/debug_blackbox.py`, `apps/etl/connectors/feiqiu/scripts/debug/analyze_architecture.py`, `apps/etl/connectors/feiqiu/scripts/run_compare_v3.py`, `apps/etl/connectors/feiqiu/scripts/run_compare_v3_fixed.py`, `apps/etl/connectors/feiqiu/scripts/full_api_refresh_v2.py`, `apps/etl/connectors/feiqiu/scripts/refresh_json_and_audit.py`, `apps/etl/connectors/feiqiu/scripts/compare_api_ods.py`, `apps/etl/connectors/feiqiu/scripts/compare_api_ods_v2.py`, `apps/etl/connectors/feiqiu/scripts/check_json_vs_md.py`, `apps/etl/connectors/feiqiu/scripts/check/check_ods_content_hash.py`, `apps/etl/connectors/feiqiu/scripts/check/check_ods_json_vs_table.py`, `apps/etl/connectors/feiqiu/scripts/repair/repair_ods_content_hash.py`, `apps/etl/connectors/feiqiu/scripts/repair/dedupe_ods_snapshots.py`, `apps/etl/connectors/feiqiu/scripts/rebuild/rebuild_db_and_run_ods_to_dwd.py`, `.kiro/steering/export-paths.md`, `docs/deployment/EXPORT-PATHS.md`, `.env.template`, `tests/test_dataflow_analyzer.py`

## TASK 4: Migrate scattered output files to export/ unified directory
- **STATUS**: in-progress
- **USER QUERIES**: User said "收尾：遍历所有报告，输出，LOG等相关文件，放到根目录的export相应目录下。"
- **DETAILS**: Created and ran migration script `scripts/ops/_migrate_scattered_outputs.py`. Successfully migrated:
  1. `docs/reports/dataflow_api_ods_dwd.md` (600KB) → `export/SYSTEM/REPORTS/full_dataflow_doc/`
  2. `apps/etl/connectors/feiqiu/reports/dwd_quality_report.json` (18KB) → `export/ETL-Connectors/feiqiu/REPORTS/`
  3. `apps/etl/connectors/feiqiu/export/JSON/` (23 old JSON dirs) → `export/ETL-Connectors/feiqiu/JSON/` (merged with existing newer data, old files skipped where target existed)
  4. `export/field_audit/dwd_field_review.md` (132KB) → `export/SYSTEM/REPORTS/field_audit/` (overwrote smaller 4KB version)
  
  Old directories cleaned: `docs/reports/`, `apps/etl/.../reports/`, `apps/etl/.../export/`, `export/field_audit/`

- **NEXT STEPS**:
  * Run verification script `scripts/ops/_verify_export.py` to confirm final state (was created but not yet executed due to context limit)
  * Delete the one-time migration scripts (`_migrate_scattered_outputs.py`, `_verify_export.py`) after verification
  * Run `/audit` — this entire multi-session change touches high-risk paths (`api/`, `config/`, `quality/`, `tasks/`, root files)
- **FILEPATHS**: `scripts/ops/_migrate_scattered_outputs.py`, `scripts/ops/_verify_export.py`

## USER CORRECTIONS AND INSTRUCTIONS:
- All output paths MUST be read from `.env` environment variables — no hardcoded fallback paths allowed (not even relative `export/...` paths)
- When env var is missing, code should raise explicit error (`KeyError`/`RuntimeError`), not silently fall back
- `scripts/ops/` scripts use shared `_env_paths.get_output_path()` utility
- ETL internal scripts use `os.environ.get("ETL_REPORT_ROOT")` + explicit error
- ETL core modules use `env_parser.py` → `AppConfig` `io.*` config chain
- `.env.template` must have all path variables uncommented (required, not optional)
- All documentation and comments in simplified Chinese (language-zh.md steering rule)
- Code identifiers stay in English
- Audit prompt_logs (`docs/audit/prompt_logs/`) are historical records and must NOT be modified
- Python scripts for multi-step ops, shell only for simple single commands
- One-time ops scripts go in `scripts/ops/`, module-specific scripts in module's `scripts/`

## KEY CODE ARCHITECTURE:
- ETL config chain: `config/defaults.py` (DEFAULTS dict, empty strings for paths) → `config/env_parser.py` (ENV_MAP + load_env_overrides) → `config/settings.py` (AppConfig.load())
- `ENV_MAP` maps env var names to dotted config paths, e.g. `"EXPORT_ROOT": ("io.export_root",)`
- `defaults.py` io paths are now `""` — if `.env` doesn't set them, downstream code gets empty string and should fail
- `dataflow_analyzer.py` is the core collection module (AnalyzerConfig, FieldInfo, ColumnInfo, TableCollectionResult, flatten_json_tree, collect_all_tables, dump_collection_results, ODS_SPECS, etc.)
- `analyze_dataflow.py` is the CLI entry point that imports from `dataflow_analyzer`

- `scripts/ops/_verify_export.py`
