# BAT-011 Verification

## Verification summary

Status: PASS

Evidence was collected against synthetic/temp data only. No production ledger DB mutation or real financial files were used.

## Acceptance criteria mapping

### REQ-015

- AC-1: PASS — `jarca_ledger_mcp/application/` 아래에 `accounts_write_services.py`, `transactions_write_services.py`, `budgets_write_services.py`, `category_rules_write_services.py`가 생성됐고 account/transaction/budget/category rule-category mutation 구현이 그쪽으로 이동했다.
- AC-2: PASS — top-level `service.py` public API, MCP tools, Streamlit/dashboard call signatures and mutation envelope contracts are preserved. MCP discovery still reports 56 tools, and export provenance shows the write APIs now resolve to the new modules.
- AC-3: PASS — targeted regression (`tests/test_service.py`, `tests/test_category_rule_filters.py`, `tests/test_ledger_categories.py`, `tests/test_contract_regression.py`) PASS, plus full `pytest -q` PASS (`42 passed, 4 skipped`).
- AC-4: PASS — BAT-011 implementation/verification docs now record actual changed files, commands, and outcomes.

## Requirement state decision

- REQ-015: Implemented.

## Remaining issues

### Hard blockers
- None.

### Non-blocking follow-up
- categorization preview/apply/workbench read-side extraction
- import pipeline split
- advanced finance workflow split
- narrower adapter surfaces under later dcy-011 batches
