-ACCOUNT SYSTEM - COMPLETE & SECURE
+MEAL ENHANCEMENTS - WORKING!

-=== ✅ FULLY IMPLEMENTED ===
+=== ✅ IMPLEMENTATION COMPLETE ===

-AUTHENTICATION SYSTEM with industry-standard security:
- User registration & login
- Secure password hashing (bcrypt cost 12)
- Session management with secure tokens
- Protected routes with middleware
- User data isolation
- All security best practices
+Meals now have:
+1. Instructions (multi-line)
+2. Prep time (minutes)
+3. Image (URL)

-=== SECURITY FEATURES ===
+=== IF MEALS/WEEK PLAN TABS DON'T LOAD ===

-✅ Password Security:
-   - Bcrypt hashing (industry standard)
-   - Min 8 characters enforced
-   - Never stored in plain text
-   - Constant-time comparison
+Your database needs the new columns!

-✅ Session Security:
-   - 256-bit cryptographically secure tokens
-   - HttpOnly cookies (XSS protection)
-   - SameSite=Strict (CSRF protection)
-   - 7-day expiry
-   - Deleted on logout
-
-✅ SQL Injection Prevention:
-   - 100% parameterized queries
-   - No string concatenation
-   - All user input sanitized
-
-✅ XSS Prevention:
-   - Template auto-escaping
-   - Input length limits
-   - Proper encoding
-
-✅ User Isolation:
-   - Every query filtered by user_id
-   - Users cannot see others' data
-   - Ownership verified on all operations
-
-=== DATABASE CHANGES ===
-
-NEW TABLES:
- users (id, email, password_hash, created_at)
- sessions (token, user_id, expires_at, created_at)
-
-UPDATED TABLES (added user_id):
- ingredients
- meals  
- week_plan
-
-ALL QUERIES NOW USER-ISOLATED
-
-=== NEW FILES ===
-
-auth/auth.go - Password hashing, tokens, validation
-auth/middleware.go - Authentication middleware
-handlers/auth.go - Login, register, logout handlers
-
-=== HOW IT WORKS ===
-
-1. USER REGISTERS:
-   - Email validated
-   - Password min 8 chars
-   - Password hashed with bcrypt
-   - User created in database
-   - Session created
-   - Cookie set
-   - Redirected to home
-
-2. USER LOGS IN:
-   - Email & password validated
-   - Password checked against hash
-   - Session created with secure token
-   - HttpOnly cookie set
-   - Redirected to home
-
-3. PROTECTED ROUTES:
-   - Middleware checks cookie
-   - Session validated
-   - User ID extracted
-   - Added to request context
-   - Handler gets user ID
-   - All DB queries filtered by user_id
-
-4. USER LOGS OUT:
-   - Session deleted from DB
-   - Cookie cleared
-   - Redirected to login
-
-=== ROUTES ===
-
-PUBLIC:
- GET/POST /login
- GET/POST /register
- GET /logout
-
-PROTECTED (require auth):
- / (home)
- /ingredients, /meals, /week-plan, /grocery-list
- All CRUD operations
-
-=== USAGE ===
-
-Fresh start:
+SOLUTION - Option 1 (Fresh start):
 rm mealprep.db
 ./start.sh

-1. Go to http://localhost:8080
-2. Redirected to /login
-3. Click "Register here"
-4. Create account
-5. Automatically logged in
-6. Use app normally
-7. Data isolated to your account
-8. Logout when done
+SOLUTION - Option 2 (Keep data):
+Just restart the server - migration runs automatically!
+./start.sh

-=== SECURITY TESTED ===
+The migration will:
+- Check if new columns exist
+- Add them if missing (instructions, prep_time, image_url)
+- Keep all your existing data
+- No data loss

-✅ SQL injection attempts blocked
-✅ XSS attacks prevented
-✅ Session hijacking mitigated
-✅ Password hashing verified
-✅ User isolation confirmed
-✅ Authentication bypass prevented
-✅ Input validation working
+=== HOW TO VERIFY ===

-=== PRODUCTION READY ===
+After restart:
+1. Go to Meals tab
+2. Form should have:
+   - Name
+   - Description
+   - Type dropdown
+   - Prep time (NEW)
+   - Image URL (NEW)
+   - Instructions textarea (NEW)

-For production use:
-1. Set cookie Secure flag to true (requires HTTPS)
-2. Add rate limiting on login/register
-3. Enable logging
-4. Monitor failed attempts
-5. Regular security audits
+If you see the new fields, it's working!

-CURRENT STATUS:
-✅ Safe for local use
-✅ Safe for trusted networks
-✅ All major vulnerabilities fixed
-✅ Industry best practices followed
+=== FEATURES ===

-=== FINAL STATUS ===
+Instructions:
+- Multi-line textarea
+- Click to expand/collapse on meal card
+- Optional

-🟢 SAFE AND READY TO USE
+Prep Time:
+- Number input (minutes)
+- Shows as "⏱️ XX min" badge
+- Optional

-The account system is:
- Fully functional
- Thoroughly tested
- Securely implemented
- Production-ready (with HTTPS)
+Image:
+- URL input
+- Shows as 120x120px thumbnail
+- Optional

-No critical security issues found.
+=== ALL FIELDS OPTIONAL ===
+
+You can:
+- Leave them blank
+- Fill only some
+- Fill all of them
+
+Old meals without these fields work fine!
+
+=== READY TO USE ===
+
+✅ Migration included
+✅ Auto-updates old databases
+✅ No data loss
+✅ All features work
+
+Just restart the server and you're good!
