+# BRIEFING — 2026-06-29T21:35:55Z
+
+## Mission
+Review the backend and DB changes implemented in M2 for correctness, robustness, type-safety, and schema conformance.
+
+## 🔒 My Identity
+- Archetype: Reviewer & Critic
+- Roles: reviewer, critic
+- Working directory: /home/ti/git/homaroma/.agents/reviewer_m2_2_v2
+- Original parent: 8e727cf6-d863-41ec-9bd2-f8dead86db2a
+- Milestone: Milestone 2: Backend & DB
+- Instance: Reviewer 2 (v2)
+
+## 🔒 Key Constraints
+- Review-only — do NOT modify implementation code
+- Network restriction: CODE_ONLY (no external URLs, curl/wget, etc.)
+- Only write files inside my own folder (/home/ti/git/homaroma/.agents/reviewer_m2_2_v2)
+
+## Current Parent
+- Conversation ID: 8e727cf6-d863-41ec-9bd2-f8dead86db2a
+- Updated: 2026-06-29T21:35:55Z
+
+## Review Scope
+- **Files to review**:
+  - `apps/backend/prisma/schema.prisma`
+  - `packages/types/index.ts`
+  - `apps/backend/src/routes/menus.ts`
+  - `apps/mcp-server/menu-tools.ts`
+  - `apps/mcp-server/menu-toolkit.ts`
+- **Interface contracts**: API endpoints, Prisma schema definitions, database structures, TypeScript definitions.
+- **Review criteria**: correctness, robustness, type-safety, schema conformance, TypeBox validation, database transaction mapping.
+
+## Key Decisions Made
+- Performed detailed review of all target M2 files.
+- Completed typescript check and ran backend E2E api verification tests.
+- Issued verdict: FAIL (Requires changes).
+
+## Artifact Index
+- /home/ti/git/homaroma/.agents/reviewer_m2_2_v2/review.md — Final review report containing findings and FAIL verdict.
+
+## Review Checklist
+- **Items reviewed**:
+  - Prisma schema (`apps/backend/prisma/schema.prisma`) — Checked (Cascade deletes ok, schema definitions match)
+  - Shared types (`packages/types/index.ts`) — Checked (Missing `isActive` in Menu type interface)
+  - Backend routes (`apps/backend/src/routes/menus.ts`) — Checked (Found transaction atomicity, unmapped fields, missing validation schema, missing import extensions, return mismatch)
+  - MCP Server tools (`menu-tools.ts` & `menu-toolkit.ts`) — Checked (Found translation spreading bug)
+- **Verdict**: FAIL (Requires Changes)
+- **Unverified claims**: Frontend layout integration (out of scope for Backend Milestone).
+
+## Attack Surface
+- **Hypotheses tested**:
+  - Transaction atomicity in PUT: Proved non-atomic due to parent `prisma` updates before transaction.
+  - Type-safety compilation under NodeNext: Proved relative import compilation errors due to missing `.js` extensions.
+  - Translation array merging: Proved spreading array of translation objects corrupts the label/title shape.
+- **Vulnerabilities found**:
+  - Database inconsistent state on partial transaction failure.
+  - Insecure PATCH route lacking TypeBox schema validation.
+- **Untested angles**: Persistent snapshot store (uses in-memory map which resets on server restart).
