# BRIEFING — 2026-06-29T01:20:34Z

## Mission
Analyze codebase and formulate implementation strategy for updating Menu/MenuItem schema, shared types, backend routes, and MCP tools with new image fields.

## 🔒 My Identity
- Archetype: Explorer
- Roles: Read-only investigator
- Working directory: /home/ti/git/homaroma/.agents/explorer_m2_3
- Original parent: 8e727cf6-d863-41ec-9bd2-f8dead86db2a
- Milestone: Milestone 2 (Backend & DB)

## 🔒 Key Constraints
- Read-only investigation — do NOT implement
- Operational code-only mode: NO external web searches, curl, wget, etc.
- No editing files outside of own directory.

## Investigation State
- **Explored paths**: `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`
- **Key findings**:
  - `Menu` and `MenuItem` models mapped in Prisma database, requiring `rootImage` (Menu) and `columnImage`/`hoverImage` (MenuItem) nullable columns.
  - Shared TypeScript interfaces in `packages/types/index.ts` must expose the same fields.
  - Elysia API routes in `menus.ts` require TypeBox validation updates and database payload mapping for POST/PUT.
  - MCP Server tools require validation changes in `menu-tools.ts` and tool schema definitions in `menu-toolkit.ts`.
- **Unexplored areas**: None, task is complete.

## Key Decisions Made
- Chose `t.Optional(t.Nullable(t.String()))` for Elysia API payload validation to preserve backward compatibility.
- Determined that database migrations must be run via `bunx prisma migrate dev` locally and `bunx prisma migrate deploy` in production.
- Kept the seed script (`seed.cjs`) unchanged as the new fields are optional.
