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**: in-progress
- **USER QUERIES**: User said "不能都使用.env的配置么？现在都是写死的路径啊，不利于维护" and "我希望现在的scripts路径下的脚本，apps下的代码，未来的kiro对话和Spec模式，以及hooks，skills，MCP中，涉及到输出文件的内容，都遵循这个规则。以上，再检查一遍。"
- **DETAILS**:

### Completed work (across 3 sessions):

**Session 1 — scripts/ops/ and ETL core modules:**
1. Created `scripts/ops/_env_paths.py` — shared utility with `get_output_path(env_var)` that does `load_dotenv` + read + mkdir + raises `KeyError` if missing
2. Updated all `scripts/ops/` scripts to use `_env_paths.get_output_path()`:
   - `analyze_dataflow.py`, `gen_dataflow_report.py`, `gen_dataflow_doc.py`, `gen_full_dataflow_doc.py`, `gen_api_field_mapping.py`, `field_audit.py`, `export_dwd_field_review.py`
3. Updated ETL core modules to raise `KeyError`/`RuntimeError` when env missing:
   - `quality/integrity_service.py`, `quality/integrity_checker.py`, `tasks/dwd/dwd_quality_task.py`
4. Updated ETL internal scripts `_build_report_path()` to use `ETL_REPORT_ROOT`:
   - `scripts/check/check_ods_content_hash.py`, `scripts/repair/repair_ods_content_hash.py`, `scripts/repair/dedupe_ods_snapshots.py`
5. Updated `REPORT_DIR` in ETL scripts to prefer `ETL_REPORT_ROOT`:
   - `scripts/run_compare_v3.py`, `scripts/run_compare_v3_fixed.py`, `scripts/full_api_refresh_v2.py`, `scripts/refresh_json_and_audit.py`
6. Updated `.env.template` — uncommented all SYSTEM/BACKEND path variables
7. Created steering rule `.kiro/steering/export-paths.md` — forbids hardcoded paths entirely
8. Updated `docs/deployment/EXPORT-PATHS.md` — removed old fallback path examples
9. Updated `.kiro/specs/dataflow-structure-audit/requirements.md` and `export/SYSTEM/REPORTS/field_audit/field_investigation_report.md` — fixed stale path references

**Session 2 — generate_report.py, test file, EXPORT-PATHS.md:**
10. Fixed `apps/etl/connectors/feiqiu/scripts/debug/generate_report.py` — `REPORTS_DIR` now reads `ETL_REPORT_ROOT` via `os.environ.get()` + `load_dotenv` + `KeyError` on missing. Updated docstring.
11. Added `import pytest` to `tests/test_dataflow_analyzer.py`
12. Updated `docs/deployment/EXPORT-PATHS.md` — replaced stale descriptions for ETL REPORTS, dataflow_analysis, and field_audit sections to reflect "no fallback, raise on missing" policy

**Session 3 — deep scan and remaining hardcoded paths:**
13. Removed `or ...docs/reports` fallback from scripts that already had `os.environ.get("ETL_REPORT_ROOT")`:
    - `scripts/run_compare_v3.py` ✅
    - `scripts/run_compare_v3_fixed.py` ✅
    - `scripts/full_api_refresh_v2.py` ✅
    - `scripts/refresh_json_and_audit.py` ✅
    - `scripts/debug/analyze_performance.py` ✅
14. Fixed completely hardcoded `docs/reports` in:
    - `scripts/debug/debug_blackbox.py` ✅ (also added `import os`)
    - `scripts/debug/analyze_architecture.py` ✅
    - `scripts/compare_api_ods_v2.py` ✅ (two locations)
    - `scripts/compare_api_ods.py` ✅ (two locations)
    - `scripts/check_json_vs_md.py` ✅
15. Fixed `api/recording_client.py` — removed `or "export/JSON"` fallback, now raises `RuntimeError` if config empty ✅
16. Fixed `config/defaults.py` — changed `io.export_root`, `io.log_root`, `io.fetch_root`, `pipeline.fetch_root` from `"export/JSON"`/`"export/LOG"` to `""` (empty string). Changed `ods.json_doc_dir` from `"export/test-json-doc"` to `""` ✅
17. Fixed `scripts/rebuild/rebuild_db_and_run_ods_to_dwd.py` — `DEFAULT_JSON_DIR` now reads from `ODS_JSON_DOC_DIR` / `INGEST_SOURCE_DIR` env vars. Updated docstring example. ✅
18. Fixed `scripts/check/check_ods_json_vs_table.py` — `json_dir` now reads from `JSON_DOC_DIR` / `ODS_JSON_DOC_DIR` env vars, raises `KeyError` if missing ✅

### Test results:
- ETL unit tests: 172 passed, 1 skipped, 1 failed (the failure is `test_cli_args.py::TestBuildCliOverrides::test_data_source_online_sets_run_key` — `AttributeError: 'Namespace' object has no attribute 'force_full'` — **pre-existing bug, NOT caused by our changes**)
- Property tests (`tests/test_dataflow_analyzer.py`): **FAILING with `ModuleNotFoundError: No module named 'dataflow_analyzer'`** — the test file imports from `dataflow_analyzer` but the actual file is `scripts/ops/analyze_dataflow.py`. The module `dataflow_analyzer` does NOT exist. The test's `sys.path.insert` adds `scripts/ops/` to path, but there's no `dataflow_analyzer.py` there.

### Scan results — remaining `"export/"` references in code (all non-output-path, safe to keep):
- `scripts/server/setup-server-git.py` — git skip-worktree prefix, not output path
- `tests/unit/test_audit_inventory.py` — test classification constant, not output path
- `scripts/audit/inventory_analyzer.py` — file classification logic, not output path

### Scan results — `"docs.*reports"` hardcoded output paths: **ZERO remaining** ✅

- **NEXT STEPS**:
  1. **CRITICAL: Fix `tests/test_dataflow_analyzer.py` import issue** — The test imports `from dataflow_analyzer import (...)` but the actual module is `analyze_dataflow.py` in `scripts/ops/`. Either:
     - Rename `analyze_dataflow.py` → `dataflow_analyzer.py` (risky, may break other references)
     - OR change the test import to `from analyze_dataflow import (...)` (safer)
     - Need to check: the test also imports `from analyze_dataflow import build_parser, resolve_output_dir` on line ~530 — so it uses BOTH names. The main symbols (`AnalyzerConfig`, `ColumnInfo`, `FieldInfo`, `TableCollectionResult`, `collect_all_tables`, `dump_collection_results`, `flatten_json_tree`) are imported as `dataflow_analyzer` but `build_parser`, `resolve_output_dir`, `generate_output_filename` are imported as `analyze_dataflow`. Also `parse_table_map`, `parse_fact_mappings`, `build_field_mappings` are imported from `dataflow_analyzer`. So the main data model classes may live in a DIFFERENT file that was deleted/renamed. Need to search for where `AnalyzerConfig`, `FieldInfo`, `flatten_json_tree` etc. are actually defined.
  2. **Update `docs/deployment/EXPORT-PATHS.md`** to reflect all the new changes from session 3 (defaults.py cleared, recording_client.py fixed, all debug scripts fixed, etc.)
  3. **Run `/audit`** — this change touches high-risk paths: `api/`, `config/`, `quality/`, `tasks/`, root files

- **FILEPATHS** (all files modified across 3 sessions):
  - `scripts/ops/_env_paths.py`
  - `scripts/ops/analyze_dataflow.py`, `gen_dataflow_report.py`, `gen_dataflow_doc.py`, `gen_full_dataflow_doc.py`, `gen_api_field_mapping.py`, `field_audit.py`, `export_dwd_field_review.py`
  - `apps/etl/connectors/feiqiu/quality/integrity_service.py`, `quality/integrity_checker.py`
  - `apps/etl/connectors/feiqiu/tasks/dwd/dwd_quality_task.py`
  - `apps/etl/connectors/feiqiu/scripts/check/check_ods_content_hash.py`, `check_ods_gaps.py`, `check_ods_json_vs_table.py`
  - `apps/etl/connectors/feiqiu/scripts/repair/repair_ods_content_hash.py`, `dedupe_ods_snapshots.py`
  - `apps/etl/connectors/feiqiu/scripts/run_compare_v3.py`, `run_compare_v3_fixed.py`, `full_api_refresh_v2.py`, `refresh_json_and_audit.py`
  - `apps/etl/connectors/feiqiu/scripts/debug/generate_report.py`, `analyze_performance.py`, `debug_blackbox.py`, `analyze_architecture.py`

  - `apps/etl/connectors/feiqiu/scripts/rebuild/rebuild_db_and_run_ods_to_dwd.py`
  - `apps/etl/connectors/feiqiu/api/recording_client.py`
  - `apps/etl/connectors/feiqiu/config/defaults.py`
  - `tests/test_dataflow_analyzer.py`
  - `.env.template`
  - `.kiro/steering/export-paths.md`
  - `docs/deployment/EXPORT-PATHS.md`

## 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
- This change touches high-risk paths — audit required but user hasn't run `/audit` yet

## KEY CODE ARCHITECTURE:
- ETL config chain: `config/defaults.py` (DEFAULTS dict, now 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

## Files to read
- `tests/test_dataflow_analyzer.py` (CRITICAL — needs import fix, read first ~20 lines and lines ~530 where `from analyze_dataflow import` appears)
- `scripts/ops/analyze_dataflow.py` (check what symbols it actually exports — `build_parser`, `resolve_output_dir`, `generate_output_filename` are there, but `AnalyzerConfig`, `FieldInfo`, `flatten_json_tree` etc. may be missing)
- `docs/deployment/EXPORT-PATHS.md` (needs update to reflect session 3 changes)
- `.kiro/steering/export-paths.md` (current steering rule)
- `scripts/ops/_env_paths.py` (shared utility)
- `apps/etl/connectors/feiqiu/config/defaults.py` (verify the empty string changes)
