BAT-009 Implementation

Plan summary

BAT-009 extends the BAT-008 valuation/read foundation into a full write workflow: manual asset CRUD, month-end snapshot preview/close/correction, mutation MCP contracts, operator dashboard UX, and baseline doc alignment while preserving shared valuation rules and safe fallback behavior.

Browser smoke: Streamlit app on http://127.0.0.1:18501/?page=자산/마감 rendered the new page with manual asset CRUD section and snapshot preview/close section; browser console JS errors 없음.

Remaining risks / follow-up notes

Correction metadata shape must remain compatible with existing read helpers and historical snapshots.
Dashboard UX should not imply production-safe automation; this batch is still synthetic-evidence only.
Automatic valuation feeds and scheduled month-end close remain explicitly out of scope for BAT-009.
