BAT-013 Implementation

Plan summary

BAT-013 implements dcy-011 Phase 6 by extracting advanced finance workflows into dedicated owning application services: cross_transfer_service.py, reconciliation_service.py, assets_service.py, and uncategorized_workbench_service.py. Existing broad modules remain as compatibility layers so MCP/service/dashboard callers keep their contracts.

Execution log

2026-07-03 07:55 KST: dcy-011 Phase 6 범위로 REQ-017/BAT-013를 생성하고 Approved 상태를 확정했다.
2026-07-03 07:57~07:59 KST: AST-extracted function ranges를 기준으로 assets / cross-transfer / reconciliation / uncategorized workbench 흐름을 새 owning services로 이동했다.
2026-07-03 07:59 KST: asset_account_services.py, import_transfer_services.py, transaction_report_services.py, categorization_services.py를 compatibility delegation 레이어로 축소했다.
2026-07-03 08:00 KST: application/__init__.py와 service.py export/proxy surface를 새 owning modules까지 확장했다.
2026-07-03 08:00~08:01 KST: targeted workflow regression, full pytest, MCP discovery, provenance checks를 실행했고 모두 PASS했다.

- asset workflows → jarca_ledger_mcp.application.assets_service
- uncategorized workbench APIs → jarca_ledger_mcp.application.uncategorized_workbench_service

Remaining risks / follow-up notes

broad compatibility layers still exist by design; final dcy-011 batch should narrow MCP/Streamlit adapter imports and refresh baseline docs.
top-level module names remain public to avoid breaking monkeypatch/tests; final cleanup should preserve this constraint.
