+# BRIEFING — 2026-06-29T17:36:00-04:00
+
+## Mission
+Verify the correctness of database, API routes, and MCP tools changes for rootImage, columnImage, and hoverImage on menus and menu items.
+
+## 🔒 My Identity
+- Archetype: critic, specialist (Empirical Challenger)
+- Roles: critic, specialist
+- Working directory: /home/ti/git/homaroma/.agents/challenger_m2_2_v3
+- Original parent: 8e727cf6-d863-41ec-9bd2-f8dead86db2a
+- Milestone: Milestone 2: Backend & DB
+- Instance: 3
+
+## 🔒 Key Constraints
+- Review-only — do NOT modify implementation code
+- Blackbox testing rules apply when evaluating MCP tools directly (strictly forbidden from reading backend source code, schema.prisma, types, etc., to discover capabilities).
+- Run verification code directly, do not trust logs or claims.
+
+## Current Parent
+- Conversation ID: 8e727cf6-d863-41ec-9bd2-fpdead86db2a
+- Updated: 2026-06-29T17:36:00-04:00
+
+## Review Scope
+- **Files to review**: Backend API routes, database schemas, and MCP tools handling menu configurations.
+- **Interface contracts**: Menu structure with `rootImage`, `columnImage`, and `hoverImage` fields.
+- **Review criteria**: Check correctness of database insertion, validation errors on invalid types, correct retrieval of fields.
+
+## Key Decisions Made
+- Spawned the MCP server dynamically in a standalone script (`test_mcp_menu_challenger.ts`) to query tools/list and test tool executions blackbox over stdio JSON-RPC.
+
+## Attack Surface
+- **Hypotheses tested**:
+  - Image fields (`rootImage`, `columnImage`, `hoverImage`) are stored and retrieved correctly by the API.
+  - The MCP server's schemas dynamically expose these fields.
+  - Invalid types passed to API or MCP tools trigger validation failures.
+- **Vulnerabilities found**:
+  - Duplicate menu creation on POST API returns 500 instead of a 409 Conflict message due to unhandled database unique constraint failure.
+  - Drift between static JSON schema files on disk and the actual live runtime schemas emitted by the MCP server.
+- **Untested angles**:
+  - Visual theme compliance in the SPA UI.
+
+## Loaded Skills
+- None
