• ✅ Created households table with id, name, invite_code, created_at
• ✅ Created household_members table for many-to-many user-household relationships
• ✅ Added household_id column to shopping_items table

2. Household Service (src/services/household.service.ts)

• ✅ createHousehold(userId, name) - Creates household and makes user owner
• ✅ joinHousehold(userId, inviteCode) - User joins household with invite code
• ✅ getMyHousehold(userId) - Get user's household with member list
• ✅ leaveHousehold(userId, householdId) - Leave or delete household
• ✅ regenerateInviteCode(userId, householdId) - Owner-only invite code regeneration
• ✅ Automatic 8-character unique invite code generation
• ✅ Proper role management (owner/member)

3. Household Routes (src/routes/households.ts)

6. Notes Per User

✅ Test Results

All tests performed successfully with two test users:

User Management

• ✅ User registration and login working
• ✅ JWT tokens generated and accepted

Household Functionality

• ✅ Household Creation: User 1 created "Test Family" household with invite code EF27Y501
• ✅ Household Joining: User 2 successfully joined using invite code
• ✅ Member Roles: User 1 = owner, User 2 = member
• ✅ Invite Code Regeneration: Owner (User 1) can regenerate → new code: 9IBNZMRM
• ✅ Permission Control: Member (User 2) cannot regenerate invite codes (403 Forbidden)

Shopping Lists

• ✅ Personal Scope: Each user sees only their own personal items
  • User 1 personal: "User1 Personal Item" (2 pieces)
  • User 2 personal: "User2 Personal Coffee" (1 bag)
• ✅ Household Scope: Both users see same household items
  • "Household Milk" (1 liter) - added by User 1
  • "Household Bread" (2 loaves) - added by User 2
• ✅ Scope Isolation: Personal and household lists completely separate

• ✅ Toggle Functionality: User 1 favorites recipe → User 2 unfavorites same recipe
• ✅ Isolated Lists: User 1 has 1 favorite, User 2 has 0 favorites

Notes System

• ✅ Per-User Notes: Each user sees only their own notes on recipes
• ✅ Content Isolation:
