# BAT-009 Manual asset CRUD / snapshot close

- Profile: standard
- Status: release-candidate
- Included REQ: REQ-011, REQ-012
- Discovery: dcy-009
- Owner: 렛저장인
- Date (KST): 2026-07-01

## 목표

REQ-011/REQ-012에 따라 `manual_assets` write lifecycle, month-end snapshot preview/close, append-only correction policy, mutation MCP, operator dashboard UX, source/is_closed 표기 정렬을 구현한다. 동시에 기존 BAT-008 read model/REQ-005 dashboard safety fallback/dcy-007 contract regression을 깨지 않도록 write/read 일관성을 유지한다.

## 산출물

- `manual_assets` create/update/deactivate write support and validation
- snapshot preview/close/correction service APIs and additive persistence metadata
- mutation MCP tools/contracts: manual asset CRUD, snapshot preview, snapshot close
- `dashboard/app.py` operator UX for manual asset management and month-end close preview/execute
- regression tests for write/read consistency, correction policy, contract envelope, dashboard fallback
- `docs/data-model.md`, `docs/interface-contract.md`, `docs/project-structure.md`, `docs/runtime-flows.md` baseline write-workflow updates
- BAT-009 planning/design/implementation/verification documents and synthetic-only evidence

## 범위 제한

- 외부 시세/부동산 자동 평가 연동
- 월말 자동 스케줄링/cron close
- 투자 조언/리밸런싱/세금/수익률 계산
- production ledger DB 실데이터 기반 evidence
