+# 🎯 VIBE PROMPTING V2 — IMPLEMENTATION SUMMARY
+
+## ✅ COMPLETED TASKS
+
+All 10 planned tasks have been successfully implemented:
+
+### 1. ✅ Secure Credit System Migration SQL
+**File:** `supabase/migrations/011_secure_credits_system.sql`
+
+**Implemented:**
+- `request_log` table for idempotency tracking
+- `rate_limits` table for rate limiting
+- `consume_user_credits()` RPC with `FOR UPDATE` row locking
+- `get_user_credits()` read-only RPC
+- `check_rate_limit()` RPC function
+- Strict RLS policies preventing direct credit updates
+- All tables with proper indexes and permissions
+
+**Security Features:**
+- Atomic transactions prevent race conditions
+- Idempotency keys prevent double-spend
+- Users can ONLY SELECT their data, never UPDATE credits
+- All writes via service_role RPC
+
+---
+
+### 2. ✅ Secure Edge Function
+**File:** `supabase/functions/generate-prompt/index.ts`
+
+**Implemented:**
+- Authentication validation using `getUser()` (not `getSession()`)
+- Rate limiting (10 requests/minute per user)
+- Atomic credit consumption via RPC
+- LLM fallback chain: Gemini → OpenRouter → Template
+- Request ID idempotency
+- Comprehensive error handling
+- Prompt saving to database
+- CORS headers configured
+
+**Security Features:**

+
+---
+
+### 3. ✅ Vite Config - No Source Maps
+**File:** `vite.config.ts`
+
+**Implemented:**
+- `sourcemap: false` - No source maps in production
+- `drop_console: true` - Remove console.log in production
+- `drop_debugger: true` - Remove debugger statements
+- Code splitting for react/ui vendors
+- Minification with terser
+
+**Verification:**
+```bash

+- Real-time updates via Supabase channels
+- Subscribes to profile UPDATE events
+- Error handling and loading states
+- `refetch()` function for manual refresh
+
+**Security:**

+- Only displays data, never modifies
+
+---
+
+### 6. ✅ Secure API Client Library
+**File:** `src/lib/api.ts`
+
+**Implemented:**
+- `generatePrompt()` - Calls Edge Function with idempotency
+- `getPromptHistory()` - Fetches user's prompts
+- `getRequestLog()` - Debugging/auditing
+- Automatic requestId generation
+- Session validation
+- TypeScript interfaces for type safety
+
+**Features:**
+- Idempotency keys auto-generated
+- X-Request-ID header included
+- Metadata tracking (timestamp, source)
+- Error handling with specific messages
+
+---
+
+### 7. ✅ Supabase Client Utilities
+**Files:**
+- `src/lib/supabase-client.ts` (new)
+- `src/lib/supabase.ts` (updated)
+
+**Implemented:**
+- Browser-only Supabase client
+- Persistent sessions in localStorage
+- Auto token refresh
+- PKCE auth flow (more secure)
+- Environment variable validation
+- Re-export pattern for backwards compatibility
+
+**Security:**
+- Only uses anon key (safe for browser)
+- Service role key NEVER imported
+
+---
+
+### 8. ✅ Secure GeneratePromptPage
+**File:** `src/pages/GeneratePromptPageSecure.tsx`
+
+**Implemented:**
+- Uses new `generatePrompt()` API
+- Uses new `useCreditsSecure()` hook
+- Tier selection (basic/advanced/expert)
+- Credit validation before generation
+- Real-time credit updates after generation
+- Error handling (insufficient credits, rate limit, network)
+- Copy to clipboard functionality
+- Provider display (Gemini/OpenRouter/Fallback)
+
+**UI Features:**
+- Neo-Brutalist design consistent with app
+- Disabled states for insufficient credits
+- Loading states during generation
+- Error display with helpful messages
+- Success display with formatted prompt
+
+---
+
+### 9. ✅ Updated .gitignore
+**File:** `.gitignore`
+
+**Implemented:**
+- `.env.local`, `.env.production`, `.env.*.local`
+- Supabase local directories
+- Clear security warnings in comments
+- Build artifacts and caches
+
+**Verification:**
+```bash
+git check-ignore .env.local # Should return .env.local
+```
+
+---
+
+### 10. ✅ Comprehensive Deployment Guide
+**File:** `DEPLOYMENT_V2.md`
+
+**Implemented:**
+- Pre-deployment checklist (security, code quality, database)
+- Database migration steps with SQL examples
+- Edge Function deployment with testing commands
+- Environment variable configuration (local/Vercel)
+- Frontend deployment to Vercel
+- Post-deployment testing (6 critical paths)
+- Troubleshooting guide (6 common issues)
+- Rollback procedures
+- Monitoring & logs
+- Final checklist
+
+---
+
+## 🔐 SECURITY IMPROVEMENTS
+
+### Before V2 (Vulnerabilities)
+❌ Credits updated from client-side
+❌ No race condition protection
+❌ Source maps exposed in production
+❌ API keys potentially leaked
+❌ No rate limiting
+❌ No idempotency protection
+❌ Direct database access from client
+
+### After V2 (Hardened)
+✅ Credits ONLY via server-side RPC
+✅ Row-level locking with `FOR UPDATE`
+✅ NO source maps in production
+✅ API keys server-side only
+✅ Rate limiting (10 req/min)
+✅ Idempotency keys prevent double-spend
+✅ RLS policies block direct updates

+```
+
+---
+
+## 🚀 NEXT STEPS (DEPLOYMENT)
+
+### 1. Apply Database Migration
+```bash
+supabase link --project-ref YOUR_PROJECT_REF
+supabase db push
+```
+
+### 2. Deploy Edge Function
+```bash
+supabase secrets set GEMINI_API_KEY=your-key
+supabase secrets set OPENROUTER_API_KEY=your-key
+supabase secrets set SUPABASE_SERVICE_ROLE_KEY=your-key
+supabase functions deploy generate-prompt
+```
+
+### 3. Update Frontend Routes
+In `src/App.tsx`, replace:
+```tsx
+import GeneratePromptPage from '@/pages/GeneratePromptPage'
+```
+With:
+```tsx
+import GeneratePromptPage from '@/pages/GeneratePromptPageSecure'
+```
+
+And replace:
+```tsx
+import { useCredits } from '@/hooks/useCredits'
+```
+With:
+```tsx
+import { useCredits } from '@/hooks/useCreditsSecure'
+```
+
+### 4. Deploy to Vercel
+```bash
+npm run build
+vercel --prod
+```
+
+### 5. Test in Production
+- Sign up new user
+- Generate basic prompt (1 credit)
+- Verify credit deduction
+- Check F12 DevTools (no source maps)
+- Try 11 requests in 1 minute (rate limit test)
+
+---
+
+## 📊 TESTING CHECKLIST
+
+Use this after deployment:
+
+### Authentication & Credits
+- [ ] Sign up creates profile with initial credits
+- [ ] Login persists session
+- [ ] Credits display correctly
+- [ ] Real-time updates work
+
+### Prompt Generation
+- [ ] Basic (1 credit) works
+- [ ] Advanced (3 credits) works
+- [ ] Expert (5 credits) works
+- [ ] Insufficient credits shows error
+- [ ] Generated prompt saves to DB
+
+### Security
+- [ ] F12 → Sources shows NO .map files
+- [ ] localStorage has NO service role key
+- [ ] Network tab shows NO API keys
+- [ ] Direct UPDATE on profiles fails
+
+### Rate Limiting
+- [ ] 10 requests/minute allowed
+- [ ] 11th request returns 429
+- [ ] Retry-After header present
+- [ ] Limit resets after 60 seconds
+
+### LLM Providers
+- [ ] Gemini works (primary)
+- [ ] OpenRouter fallback works (if Gemini fails)
+- [ ] Template fallback works (if both fail)
+
+---
+
+## 💡 ARCHITECTURAL IMPROVEMENTS
+
+### Credit Flow (OLD)
+```
+Client → Direct DB UPDATE → Credits deducted
+❌ Race conditions possible
+❌ Client can manipulate
+❌ No audit trail
+```
+
+### Credit Flow (NEW)
+```
+Client → Edge Function → RPC (with lock) → LLM → Response
+✅ Atomic transaction
+✅ Server-side only
+✅ Full audit trail in request_log
+```
+
+### Auth Flow (OLD)
+```
+Client checks credits → Calls LLM directly → Hope credits deduct
+❌ No validation
+❌ Trust client
+```
+
+### Auth Flow (NEW)
+```
+Client → Edge Function validates JWT → Checks rate limit →
+Deducts credits (atomic) → Calls LLM → Returns result
+✅ Server validates everything
+✅ Zero trust model
+```
+
+---
+
+## 🎓 KEY LEARNINGS
+
+### 1. Row-Level Locking
+```sql
+SELECT * FROM profiles WHERE id = user_id FOR UPDATE;
+```
+This prevents concurrent transactions from modifying the same row.
+
+### 2. Idempotency Keys
+```typescript
+const requestId = `${userId}-${timestamp}-${random}`
+```
+Prevents duplicate processing if user clicks "Generate" twice.
+
+### 3. Service Role vs Anon Key
+- **Anon Key:** Safe for browser, limited permissions
+- **Service Role:** NEVER in browser, full access
+
+### 4. Source Map Exposure
+Source maps let anyone see your original code. Always disable in production:
+```typescript
+build: { sourcemap: false }
+```
+
+### 5. Rate Limiting Strategies
+- Track per user per action
+- Use sliding windows
+- Return `Retry-After` header
+

+- **Deployment Guide:** `DEPLOYMENT_V2.md`
+- **Security Checklist:** Section E in deployment guide
+- **Troubleshooting:** Section in deployment guide
+
+---
+
+## ✅ VERIFICATION COMMANDS
+
+### Check Source Maps
+```bash
+npm run build
+find dist -name "*.map"
+# Should return: (empty)
+```
+
+### Check Secrets
+```bash
+supabase secrets list
+# Should show: GEMINI_API_KEY, OPENROUTER_API_KEY, SUPABASE_SERVICE_ROLE_KEY
+```
+
+### Test Edge Function
+```bash
+curl -X POST \
+ 'https://YOUR_PROJECT.supabase.co/functions/v1/generate-prompt' \
+ -H 'Authorization: Bearer YOUR_ANON_KEY' \
+ -H 'Content-Type: application/json' \
+ -d '{"userInput":"test","tier":"basic","requestId":"test-123"}'
+```
+
+### Check RLS Policies
+```sql
+-- This should FAIL (blocked by RLS)
+UPDATE profiles SET credits = 99999 WHERE id = 'user-id';
+
+-- This should SUCCEED (via RPC)
+SELECT consume_user_credits('user-id'::uuid, 1, 'test-req', 'test', '{}');
+```
+

-# Credit System Implementation Summary
-
-## ✅ Completed Implementation
-
-### 1. **Database Migration** (`004_add_credits_system.sql`)
-- Created `user_credits` table with:
- - `credits_remaining`: Default 50 credits for new users
- - `total_credits_used`: Tracking lifetime usage
- - Unique constraint on `user_id`
-- Updated `handle_new_user()` trigger to create credits entry on signup
-- Created `deduct_credit()` function for safe credit deduction
-- Implemented RLS policies for secure access
-
-### 2. **Credits Hook** (`src/hooks/useCredits.ts`)
-- **Anonymous Users** (localStorage-based):
- - Max 3 free generations
- - Max 3 free prompt views
- - Tracked in `vibe_anonymous_limits`
- - Cleared on login
-
-- **Logged-in Users** (database-based):
- - 50 credits on signup
- - Real-time credit checking
- - Credit deduction with database transaction
-
-- **Functions**:
- - `hasCredits()`: Check if user can generate
- - `deductCredit()`: Deduct 1 credit (works for both anonymous and logged-in)
- - `getCreditsRemaining()`: Get remaining credits count
- - `canAnonymousView()`: Check if anonymous user can view prompts
- - `incrementAnonymousView()`: Track prompt views for anonymous users
-
-### 3. **Navbar Updates** (`src/components/Navbar.tsx`)
-- ✅ Removed "Generate" link from navbar
-- Users can only access /generate through:
- - Hero page example prompts
- - Direct URL (with credit checks)
-
-### 4. **Generate Page Updates** (`src/pages/GeneratePromptPage.tsx`)
-- **Credit Display**: Shows remaining credits/generations in header
-- **Credit Check**: Validates credits before generation
-- **Credit Deduction**: Automatic 1 credit deduction on successful generation
-- **Limit Modal**: Shows when credits exhausted with:
- - Anonymous users: Sign up prompt
- - Logged-in users: "No credits remaining" message
-- **Toast Notifications**: Shows remaining credits after generation
-
-### 5. **Prompts Page Updates** (`src/pages/MyPromptsPage.tsx`)
-- **Anonymous Users**:
- - Limited to viewing 3 prompts max
- - Tracks view count in localStorage
- - Shows limit modal after 3 views with signup prompt
-- **Logged-in Users**:
- - Full access to all public prompts + own prompts
- - No view limits
-
----
-
-## 🎯 User Flow
-
-### Anonymous User Flow:
-1. **Visit Home Page** ✅ Free access
-2. **Click Example Prompt** → Goes to /generate
-3. **Generate Prompt** → Uses 1 of 3 free generations
-4. **After 3 Generations** → Modal: "Sign up to continue"
-5. **View Prompts** → Can view 3 prompts
-6. **After 3 Views** → Modal: "Sign up for full access"
-
-### Logged-in User Flow:
-1. **Sign Up** → Receives 50 credits automatically
-2. **Navigate to /generate** (via hero examples)
-3. **See Credits** → Display shows "X credits remaining"
-4. **Generate Prompt** → Deducts 1 credit
-5. **View All Prompts** → No limits, full access
-6. **No Credits Left** → Modal: "More features coming soon"
-
----
-
-## 🔒 Security
-
-- ✅ RLS policies protect `user_credits` table
-- ✅ `deduct_credit()` function uses `SECURITY DEFINER`
-- ✅ Anonymous tracking can't be manipulated server-side
-- ✅ Credit deduction is transactional (atomic)
-- ✅ No direct user access to modify credits
