+# Milestone 2 Verification and Challenge Report
+
+## Challenge Summary
+
+**Overall risk assessment**: LOW
+
+The additions of `rootImage` to the Menu model and `columnImage` / `hoverImage` to the MenuItem model are fully implemented and function correctly at all layers: DB, backend API, and MCP tool runtime. Data is stored and retrieved accurately, and validation rules reject invalid types on both the API and MCP boundaries.
+
+We identified two minor issues during testing:
+1. **API Robustness**: Creating a duplicate menu returns `500 Failed to create menu` instead of a friendly `409 Conflict`.
+2. **Schema Drift**: The static schema definitions stored in the MCP app directory (e.g., `upsert_menu.json`) do not reflect the new fields, though the runtime schema returned by the running server is correct.
+

+
+## Challenges
+
+### [Medium] Challenge 1: Duplicate Menu Name triggers generic 500 Internal Server Error
+
+- **Assumption challenged**: The API should handle duplicate name entry gracefully and return a clear user/client feedback response (e.g., 409 Conflict).
+- **Attack scenario**: Sending a POST request to `/api/menus` with a name that already exists in the database.
+- **Blast radius**: The client receives a generic `500 Failed to create menu`. This obscures DB constraints as server errors and makes client debugging harder.
+- **Mitigation**: Update the error handling in `apps/backend/src/routes/menus.ts` (POST `/menus`) to catch Prisma unique constraint failures (Error code `P2002`) and return a `409 Conflict` status with a descriptive error message.
+
+### [Low] Challenge 2: Static MCP tool JSON files are outdated
+
+- **Assumption challenged**: The schema definition files on disk in the application directory `/home/ti/.gemini/antigravity/mcp/homaroma_mcp/` should be in sync with the actual tool capabilities.
+- **Attack scenario**: An agent or developer reads `/home/ti/.gemini/antigravity/mcp/homaroma_mcp/upsert_menu.json` to discover input parameters and assumes `rootImage`, `columnImage`, and `hoverImage` are unsupported.
+- **Blast radius**: Documentation drift and developer confusion.
+- **Mitigation**: Regenerate or update the static schema files on disk to include the new fields.

+
+## Stress Test Results
+
+| Scenario | Expected Behavior | Actual Behavior | Pass/Fail |
+|---|---|---|---|
+| **API Menu Creation (Valid)** | Return `200 OK` with stored `rootImage`, `columnImage`, `hoverImage` | Successfully created menu & items, returned exact fields. | **PASS** |
+| **API Menu Retrieval (Valid)** | GET `/menus/:name` retrieves correct image fields | Correct fields returned. | **PASS** |
+| **API Menu Update (Valid)** | PUT `/menus/:name` updates image fields correctly | Correct fields updated and returned. | **PASS** |
+| **API Type Validation** | Rejects invalid types for `rootImage` and `columnImage`/`hoverImage` | Returned `422 Unprocessable Entity` with specific schema validation mismatch messages. | **PASS** |
+| **MCP List Tools** | `tools/list` returns schema including `rootImage`, `columnImage`, `hoverImage` | Discovered fields are properly defined. | **PASS** |
+| **MCP Upsert Menu (Valid)** | Creates menu with new fields via JSON-RPC stdin/stdout | Returned `success: true` and the correct fields. | **PASS** |
+| **MCP Upsert Menu (Invalid)** | Rejects invalid types with validation error | Returned tool execution error specifying the validation issue. | **PASS** |

+
+## Unchallenged Areas
+
+- **Theme Compliance**: We verified database storage, APIs, and tool contracts. CSS/HTML visual rendering of these images in the SPA is not checked, as it is outside the scope of Milestone 2 (Backend & DB).
+- **Other sections**: Other CMS components/sections were not tested under this specific menu validation run.
