# BRIEFING — 2026-06-29T01:20:34Z

## Mission
Analyze codebase and formulate a precise read-only implementation strategy for adding menu image fields to Prisma schema, shared types, backend route, and MCP tools.

## 🔒 My Identity
- Archetype: explorer
- Roles: Teamwork explorer, Read-only investigator
- Working directory: /home/ti/git/homaroma/.agents/explorer_m2_1
- Original parent: 8e727cf6-d863-41ec-9bd2-f8dead86db2a
- Milestone: Milestone 2: Backend & DB

## 🔒 Key Constraints
- Read-only investigation — do NOT implement
- Code only network mode (no external network, curl, wget, lynx, etc.)
- Do not make file writes outside working directory except for reports/handoffs in my folder

## Current Parent
- Conversation ID: 8e727cf6-d863-41ec-9bd2-f8dead86db2a
- Updated: 2026-06-29T01:21:00Z

## 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`
  - `apps/mcp-server/index.ts`
- **Key findings**: 
  - Detailed the modifications needed in the Prisma models, route schema validation, mapping logic in transaction hooks, and tool integration interface schemas.
  - Determined that the database changes are safe and backwards-compatible.
- **Unexplored areas**: None.

## Key Decisions Made
- Outlined a precise code modification plan without implementation (read-only mode compliance).
- Recommended use of `bunx prisma migrate dev` in line with backend package config.
