## Deployment

### Environment Variables
```
VITE_SUPABASE_URL=
VITE_SUPABASE_PUBLISHABLE_KEY=
VITE_DESCOPE_PROJECT_ID=
VITE_ESCROW_PIN_SALT=
```

### Build Process
```bash
npm run build
npm run preview  # Always verify production build locally before deploying
```

### Vite Build Configuration (`vite.config.ts`)

The project uses Vite with `@vitejs/plugin-react-swc` and `vite-plugin-pwa`.

**Critical rule â€” `manualChunks`:**  
Do **not** assign libraries that call `React.createContext()` or `React.useContext()` at module evaluation time into a separate chunk from React. This causes a Rollup cross-chunk Temporal Dead Zone (TDZ) crash at runtime (`ReferenceError: Cannot access 'X' before initialization`).

Libraries known to call React at top-level (unsafe to split from React):
- `react-hook-form`
- `@radix-ui/*` primitives
- `@tanstack/react-query`

The current config intentionally omits `manualChunks` and relies on Vite's default splitting. See [`INCIDENT_PROD_TDZ_CRASH_2026-06-15.md`](./INCIDENT_PROD_TDZ_CRASH_2026-06-15.md) for full incident details.

### Deployment
- **Platform**: Vercel
- **Production branch**: `alpha` (not `main`)
- **Custom domain**: `www.hna.africa`
- Every push to `alpha` triggers an automatic Vercel production deployment.

## Testing

### Unit Tests
- Component testing with React Testing Library
- Service layer testing

### Integration Tests
- API integration tests
- Database operation tests

### E2E Tests
- Playwright for end-to-end testing
- User journey testing

## Recent Technical Changes

### 2026-06-15 â€” P0 Production Fix: Remove `manualChunks` from `vite.config.ts`
- **Problem**: Custom `manualChunks` split `react-hook-form`/`zod` into a `forms` chunk separate from React (`vendor` chunk), causing a TDZ crash on every page load in production
- **Fix**: Removed entire `manualChunks` block; Vite default splitting now handles all chunks
- **File changed**: `vite.config.ts`
- **Commits**: `63d8cdc`, `174dba2`

<!-- Auto-generated technical changes will appear here -->

## Troubleshooting

### Common Issues

#### Build Errors
- Check Node.js version (18+)
- Clear node_modules and reinstall
- Verify environment variables

#### Production White Blank Page â€” `ReferenceError: Cannot access 'X' before initialization`
- **Cause**: Cross-chunk TDZ crash â€” a library chunk references React before the React chunk has initialized
- **Symptom**: App fails to mount entirely; error appears in browser console pointing to a bundled `.js` file at a specific byte offset
- **Fix**: Remove or simplify `manualChunks` in `vite.config.ts`; never split React-dependent libraries into separate chunks from React
- **Note**: This bug does **not** appear in `vite dev` â€” only in production builds. Always run `npm run build && npm run preview` before deploying
- **Full details**: [`INCIDENT_PROD_TDZ_CRASH_2026-06-15.md`](./INCIDENT_PROD_TDZ_CRASH_2026-06-15.md)

#### Database Connection
- Verify Supabase credentials
- Check network connectivity
- Review RLS policies

#### Authentication Issues
- Verify Descope configuration
- Check JWT token validity
- Review session management

## Development Guidelines

### Code Style
- TypeScript strict mode (disabled for flexibility)
- ESLint for code quality
- Prettier for formatting

### Component Structure
- Functional components with hooks
- Props interface definitions
- Proper TypeScript typing

### Commit Messages
- Follow conventional commits format

VITE_PAYSTACK_SECRET_KEY=sk_test_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
```

#### Configuring Webhook URLs for Local Development

1. Install and start [ngrok](https://ngrok.com/):
   ```bash
   ngrok http 8087
   # Note the HTTPS URL, e.g. https://abc123.ngrok.io
   ```
2. In the Paystack dashboard go to **Settings** → **API Keys & Webhooks**
3. Set the webhook URL to: `https://abc123.ngrok.io/api/webhooks/paystack`
4. Copy the webhook secret shown and set it as `VITE_WEBHOOK_SECRET` in your `.env`

#### Triggering Test Payment Events

Use Paystack test cards to simulate payment outcomes:

| Card Number | Outcome |
|---|---|
| `4084084084084081` | Success |
| `5060666666666666666` | Insufficient funds |
| `5078 5078 5078 5078 12` | Declined |

You can also simulate events directly from the Paystack dashboard under **Transactions** → select a test transaction → **Resend Webhook**.

## Escrow, Encryption & Optional Variables

These variables are not payment-provider credentials but are read by the app at
runtime. The escrow/encryption values are security-sensitive and must be set to
strong, unique values in every non-local environment.

### Escrow PIN Salt (security-sensitive)

`VITE_ESCROW_PIN_SALT` is appended to escrow PINs before SHA-256 hashing
(`src/services/escrow.ts`). It falls back to an insecure default when unset, so it
**must** be overridden outside local development.

```bash
# Generate with: openssl rand -hex 32
VITE_ESCROW_PIN_SALT=your_escrow_pin_salt_here
```

### Encryption Key (security-sensitive)

`VITE_ENCRYPTION_KEY` is the AES-256-GCM key used by the client-side encryptor
(`src/lib/encryptor.ts`) for encrypting sensitive values before storage.

```bash
# Generate with: openssl rand -hex 32
VITE_ENCRYPTION_KEY=your_encryption_key_here
```

### Optional Integrations

These degrade gracefully when unset — the related feature is simply disabled.

```bash
# Currency conversion (src/services/currency.ts) — falls back to bundled rates.
VITE_EXCHANGE_RATE_API_KEY=your_exchange_rate_api_key_here

# Sentry error monitoring (src/lib/sentry.ts) — reporting disabled when unset.
VITE_SENTRY_DSN=your_sentry_dsn_here
```

---

## Webhook Configuration

Webhooks allow payment providers to notify your application about payment events.

### Application URL

```bash
# Local Development (use ngrok or similar)
VITE_APP_URL=https://your-ngrok-url.ngrok.io

# Staging / Dev
VITE_APP_URL=https://home-n-away.vercel.app

# Production
VITE_APP_URL=https://hna.africa
```

### Webhook Secret

Generate a secure random string for webhook verification:

```bash
# Generate using Node.js
node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"

# Or use OpenSSL
openssl rand -hex 32
```

```bash
VITE_WEBHOOK_SECRET=your_generated_secret_key_here
```

### Webhook URLs

Configure these URLs in your payment provider dashboards:

#### Paystack Webhooks

1. Go to **Settings** → **API Keys & Webhooks**
2. Add webhook URL: `https://your-domain.com/webhooks/paystack`
3. Copy the webhook secret provided by Paystack

#### M-Pesa Callbacks

1. In your M-Pesa app configuration
2. Set callback URL: `https://your-domain.com/webhooks/mpesa`
3. Ensure URL is publicly accessible

#### MTN Webhooks

1. In MTN MoMo dashboard
2. Configure callback URL: `https://your-domain.com/webhooks/mtn`

### Local Development Webhooks

For local testing, use [ngrok](https://ngrok.com/):

```bash
# Start ngrok
ngrok http 8087

# Use the HTTPS URL provided
# Example: https://abc123.ngrok.io

# Update .env
VITE_APP_URL=https://abc123.ngrok.io
```

---

## Environment Modes

### Development Mode

```bash
# .env.development
VITE_PAYSTACK_PUBLIC_KEY=pk_test_...
VITE_MPESA_CONSUMER_KEY=sandbox_key...
VITE_APP_URL=http://localhost:8087
```

### Production Mode

```bash
# .env.production
VITE_PAYSTACK_PUBLIC_KEY=pk_live_...
VITE_MPESA_CONSUMER_KEY=production_key...
VITE_APP_URL=https://hna.africa
```

### Building for Different Environments

```bash
# Development build
npm run build:dev

# Production build
npm run build
```

---

## Troubleshooting

### App Shows "Environment Error" Screen on Boot

**Symptom**: Instead of the app, an `EnvErrorScreen` lists missing variables

**Cause**: A required variable (`VITE_SUPABASE_URL` or `VITE_SUPABASE_PUBLISHABLE_KEY`)
is missing or empty. A common mistake is naming the key `VITE_SUPABASE_ANON_KEY`
— the validator expects `VITE_SUPABASE_PUBLISHABLE_KEY`.

**Solution**:
1. Ensure `.env` defines both `VITE_SUPABASE_URL` and `VITE_SUPABASE_PUBLISHABLE_KEY`
2. Restart the dev server (Vite only reads `.env` at startup)

### Missing Environment Variables

**Symptom**: Console errors about undefined environment variables

**Solution**: 
1. Check `.env` file exists
2. Restart dev server after adding variables
3. Verify variable names start with `VITE_`

```bash
# Restart dev server
npm run dev
```

### Payment Initialization Fails

**Symptom**: "Failed to initialize payment" error

**Solution**:
1. Verify API keys are correct
2. Check if using test keys in development
3. Ensure keys don't have extra spaces or quotes

```typescript
// Debug in browser console
console.log('Paystack Key:', import.meta.env.VITE_PAYSTACK_PUBLIC_KEY);
```

### Webhook Not Receiving Callbacks

**Symptom**: Payments succeed but booking not confirmed

**Solution**:
1. Verify webhook URL is publicly accessible
2. Check webhook URL in provider dashboard
3. Test webhook with provider's testing tools
4. Check server logs for webhook errors

```bash
# Test webhook locally with ngrok
ngrok http 8087

# Update provider dashboard with ngrok URL
```

### M-Pesa STK Push Timeout

**Symptom**: "Request timeout" error

**Solution**:
1. Verify phone number format (254XXXXXXXXX)
2. Check if shortcode is correct
3. Ensure passkey matches shortcode
4. Test with sandbox credentials first

### Paystack Webhook Signature Verification Fails

**Symptom**: "Invalid webhook signature" error

**Solution**:
1. Verify `VITE_PAYSTACK_SECRET_KEY` is correct
2. Check webhook secret in Paystack dashboard
3. Ensure raw request body is used for verification

---

## Security Best Practices

### 1. Never Commit Secrets

```bash
# Add to .gitignore
.env
.env.local
.env.production
```

### 2. Use Different Keys for Environments

- **Development**: Test/Sandbox keys
- **Production**: Live keys

### 3. Rotate Keys Regularly

- Change API keys every 90 days
- Update webhook secrets periodically

### 4. Restrict API Key Permissions

- Use read-only keys where possible
- Limit IP addresses if supported

### 5. Monitor for Suspicious Activity

- Set up alerts for failed payment attempts
- Monitor webhook delivery failures
- Track unusual transaction patterns

# Phase 1 Database Migration Guide

## Overview

This guide covers the database schema changes for Phase 1: Core Marketplace Functionality. The migration adds 7 new tables and updates the existing `bookings` table to support payment processing, escrow management, notifications, and booking lifecycle tracking.

## Migration Files

- **Main Migration**: `20250107000001_phase1_core_marketplace.sql`

## Updated Tables

### bookings
**Changes**: Updated status constraint to include new values

**New Status Values**:
- `checked_in`: Guest has checked in
- `checked_out`: Guest has checked out
- `payment_failed`: Payment processing failed

**Status Flow**:
```
pending → confirmed → checked_in → checked_out → completed
    ↓
cancelled / payment_failed
```

## Row Level Security (RLS)

All new tables have RLS enabled with policies that ensure:

1. **payment_events**: Only admins and transaction participants can view
2. **escrows**: Only tenant, property owner, and admins can view/update
3. **escrow_disputes**: Only dispute creator, involved parties, and admins can view
4. **cancellation_requests**: Only booking participants and admins can view
5. **notification_preferences**: Users can only manage their own preferences
6. **notifications**: Users can only view their own notifications
7. **booking_status_history**: Only booking participants and admins can view

## Running the Migration

### Local Development (Supabase CLI)

```bash
# Apply migration
supabase db push

# Or apply specific migration
supabase migration up
```

### Production (Supabase Dashboard)

1. Go to Database → Migrations
2. Upload `20250107000001_phase1_core_marketplace.sql`
3. Review changes
4. Apply migration

### Manual Application

```bash
# Connect to your database
psql -h your-db-host -U postgres -d your-database

# Run migration
\i supabase/migrations/20250107000001_phase1_core_marketplace.sql
```

## Testing the Migration

### 1. Verify Tables Created

```sql
-- Check all tables exist
SELECT table_name 
FROM information_schema.tables 
WHERE table_schema = 'public' 
AND table_name IN (
  'payment_events', 
  'escrows', 
  'escrow_disputes', 
  'cancellation_requests',
  'notification_preferences',
  'notifications',
  'booking_status_history'
);
```

### 2. Verify Indexes

```sql
-- Check indexes for payment_events
SELECT indexname 
FROM pg_indexes 
WHERE tablename = 'payment_events';
```

### 3. Verify RLS Policies

```sql
-- Check RLS is enabled
SELECT tablename, rowsecurity 
FROM pg_tables 
WHERE schemaname = 'public' 
AND tablename IN (
  'payment_events', 
  'escrows', 
  'escrow_disputes', 
  'cancellation_requests',
  'notification_preferences',
  'notifications',
  'booking_status_history'
);

-- Check policies exist
SELECT tablename, policyname 
FROM pg_policies 
WHERE schemaname = 'public';
```

### 4. Test Data Insertion

```sql
-- Test payment_events
INSERT INTO payment_events (reference, gateway, event_type, status)
VALUES ('TEST-001', 'paystack', 'test_event', 'success');

-- Verify insertion
SELECT * FROM payment_events WHERE reference = 'TEST-001';

-- Clean up
DELETE FROM payment_events WHERE reference = 'TEST-001';
```

## Rollback Procedure

If you need to rollback the migration:

```bash
# Using Supabase CLI
supabase db reset

# Or manually
psql -h your-db-host -U postgres -d your-database \
  -f supabase/migrations/20250107000001_phase1_core_marketplace_rollback.sql
```

**⚠️ WARNING**: Rollback will permanently delete all data in the new tables. Ensure you have backups before proceeding.

## Post-Migration Steps

1. **Update Environment Variables**
   - Add payment provider credentials
   - Configure webhook URLs
   - Set encryption keys

2. **Test Payment Flows**
   - Test Paystack sandbox
   - Test M-Pesa sandbox
   - Verify webhook delivery

3. **Verify RLS Policies**
   - Test as different user roles
   - Ensure data isolation works correctly

4. **Monitor Performance**
   - Check query performance
   - Monitor index usage
   - Optimize if needed

## Troubleshooting

### Migration Fails

**Issue**: Foreign key constraint errors

**Solution**: Ensure the `properties`, `bookings`, and `users` tables exist before running migration

```sql
-- Check required tables exist
SELECT table_name 
FROM information_schema.tables 
WHERE table_name IN ('properties', 'bookings', 'users');
```

### RLS Policies Not Working

**Issue**: Users can't access their own data

**Solution**: Verify auth.uid() returns correct user ID

```sql
-- Test as authenticated user
SELECT auth.uid();

-- Check user mapping
SELECT id, auth_user_id FROM users WHERE auth_user_id = auth.uid();
```

### Performance Issues

**Issue**: Slow queries on new tables

**Solution**: Verify indexes are created

```sql
-- Check index usage
SELECT schemaname, tablename, indexname, idx_scan
FROM pg_stat_user_indexes
WHERE tablename IN ('payment_events', 'escrows', 'notifications')
ORDER BY idx_scan DESC;
```

# Webhook Implementation Review

## Overview

This document provides a detailed review of the webhook implementation in `src/pages/Webhooks.tsx`, including architecture decisions, security considerations, and recommendations for improvement.

## Architecture

    participant DB as Database
    participant UI as User Interface

    PP->>WH: Callback with payment data
    WH->>RL: Check rate limit

        WH->>UI: Show success toast
    else Rate limit exceeded
        WH->>UI: Show rate limit error
    end
```

## Implementation Details

### 1. Rate Limiting

**Implementation**:
```typescript
const webhookRateLimiter = new Map<string, { count: number; resetTime: number }>();
const RATE_LIMIT_WINDOW = 60000; // 1 minute
const MAX_REQUESTS_PER_WINDOW = 10;

const checkRateLimit = (gateway: string): boolean => {
  const now = Date.now();
  const key = `webhook_${gateway}`;
  const limiter = webhookRateLimiter.get(key);

  if (!limiter || now > limiter.resetTime) {
    webhookRateLimiter.set(key, {
      count: 1,
      resetTime: now + RATE_LIMIT_WINDOW
    });
    return true;
  }

  if (limiter.count >= MAX_REQUESTS_PER_WINDOW) {
    return false;
  }

  limiter.count++;
  return true;
};
```

**Pros**:
- ✅ Simple implementation
- ✅ No external dependencies
- ✅ Fast performance
- ✅ Per-gateway rate limiting

**Cons**:
- ⚠️ Resets on server restart
- ⚠️ Not shared across multiple server instances
- ⚠️ Memory-based (not persistent)

**Recommendations**:
1. **For Production**: Implement Redis-based rate limiting
   ```typescript
   import Redis from 'ioredis';
   const redis = new Redis(process.env.REDIS_URL);
   
   const checkRateLimit = async (gateway: string): Promise<boolean> => {
     const key = `webhook_ratelimit:${gateway}`;
     const count = await redis.incr(key);
     
     if (count === 1) {
       await redis.expire(key, 60); // 60 seconds
     }
     
     return count <= MAX_REQUESTS_PER_WINDOW;
   };
   ```

2. **Alternative**: Use Supabase Edge Functions with Deno KV
   ```typescript
   const kv = await Deno.openKv();
   const key = ["webhook_ratelimit", gateway];
   const result = await kv.atomic()
     .sum(key, 1)
     .commit();
   ```

### 2. Paystack Webhook Handler

**Implementation**:
```typescript
const handlePaystackWebhook = async (reference: string) => {
  try {
    const paymentData = await paystackService.verifyPayment(reference);
    
    if (paymentData.status === 'success') {
      await updateBookingAndEscrow(
        reference,
        'paystack',
        paymentData.amount / 100, // Convert from kobo
        paymentData.currency,
        paymentData.id.toString()
      );
    } else {
      throw new Error(`Payment verification failed: ${paymentData.gateway_response}`);
    }
  } catch (error) {
    console.error('Paystack webhook error:', error);
    throw error;
  }
};
```

**Security Analysis**:

✅ **Strengths**:
1. Verifies payment with Paystack API (doesn't trust webhook alone)
2. Checks payment status before processing
3. Converts currency correctly (kobo to naira)
4. Comprehensive error handling

⚠️ **Potential Issues**:
1. No webhook signature verification in this function
2. Relies on paystackService for signature verification

**Signature Verification** (in paystackService):
```typescript
private verifyWebhookSignature(payload: string, signature: string): boolean {
  const crypto = require('crypto');
  const hash = crypto
    .createHmac('sha512', this.secretKey)
    .update(payload, 'utf8')
    .digest('hex');
  
  return hash === signature;
}
```

✅ **This is correct** - Uses HMAC SHA-512 as per Paystack documentation

**Recommendations**:
1. Add signature verification to webhook handler:
   ```typescript
   const handlePaystackWebhook = async (reference: string, signature: string) => {
     // Verify signature first
     if (!paystackService.verifyWebhookSignature(payload, signature)) {
       throw new Error('Invalid webhook signature');
     }
     // Then proceed with verification
   }
   ```

2. Add replay attack prevention:
   ```typescript
   const processedWebhooks = new Set<string>();
   
   if (processedWebhooks.has(reference)) {
     throw new Error('Webhook already processed');
   }
   processedWebhooks.add(reference);
   ```

### 3. M-Pesa Webhook Handler

**Implementation**:
```typescript
const handleMpesaWebhook = async (checkoutRequestId: string) => {
  try {
    const response = await mpesaService.querySTKPush(checkoutRequestId);
    
    if (response.ResponseCode === '0') {
      const metadata = searchParams.get('metadata');
      const amount = metadata ? JSON.parse(metadata).amount : 0;
      
      await updateBookingAndEscrow(
        checkoutRequestId,
        'mpesa',
        amount,
        'KES',
        response.CheckoutRequestID || checkoutRequestId
      );
    } else {
      throw new Error(`M-Pesa verification failed: ${response.ResponseDescription}`);
    }
  } catch (error) {
    console.error('M-Pesa webhook error:', error);
    throw error;
  }
};
```

**Security Analysis**:

✅ **Strengths**:
1. Queries M-Pesa API for verification
2. Checks ResponseCode for success
3. Error handling with descriptive messages

⚠️ **Potential Issues**:
1. Amount extracted from URL parameter (could be manipulated)
2. No signature verification (M-Pesa doesn't provide webhook signatures)

**Recommendations**:
1. Store amount in escrow record, don't rely on URL parameter:
   ```typescript
   // Get amount from escrow record instead
   const { data: escrow } = await supabase
     .from('escrows')
     .select('amount, currency')
     .eq('reference', checkoutRequestId)
     .single();
   
   await updateBookingAndEscrow(
     checkoutRequestId,
     'mpesa',
     escrow.amount, // Use stored amount
     escrow.currency,
     response.CheckoutRequestID
   );
   ```

2. Add IP whitelist for M-Pesa callbacks:
   ```typescript
   const MPESA_IPS = ['196.201.214.200', '196.201.214.206'];
   
   const verifyMpesaIP = (ip: string): boolean => {
     return MPESA_IPS.includes(ip);
   };
   ```

### 4. Database Update Logic

**Implementation**:
```typescript
const updateBookingAndEscrow = async (
  reference: string,
  gateway: string,
  amount: number,
  currency: string,
  transactionId: string
): Promise<void> => {
  try {
    // 1. Log payment event
    await supabase.from('payment_events').insert([{...}]);
    
    // 2. Find escrow
    const escrowClient: any = supabase;
    const escrowResult: any = await escrowClient
      .from('escrows')
      .select('*')
      .eq('reference', reference)
      .single();
    
    // 3. Update escrow
    await escrowClient.from('escrows').update({
      status: 'held',
      paid_at: new Date().toISOString(),
      transaction_id: transactionId,
      gateway_response: JSON.stringify({ gateway, amount, currency })
    }).eq('id', escrow.id);
    
    // 4. Update booking
    await escrowClient.from('bookings').update({
      status: 'confirmed'
    }).eq('id', bookingId);
    
    // 5. Create status history
    await escrowClient.from('booking_status_history').insert([{...}]);
  } catch (error) {
    console.error('Error updating booking and escrow:', error);
    throw error;
  }
};
```

**Transaction Safety**:

⚠️ **Issue**: No database transaction wrapping

**Problem**: If step 3 succeeds but step 4 fails, escrow is updated but booking is not.

**Recommendation**: Use Supabase RPC with PostgreSQL transaction:

```sql
-- Create RPC function
CREATE OR REPLACE FUNCTION update_booking_and_escrow(
  p_reference TEXT,
  p_transaction_id TEXT,
  p_gateway_response TEXT
)
RETURNS void AS $$
BEGIN
  -- Update escrow
  UPDATE escrows
  SET status = 'held',
      paid_at = NOW(),
      transaction_id = p_transaction_id,
      gateway_response = p_gateway_response
  WHERE reference = p_reference;
  
  -- Update booking
  UPDATE bookings
  SET status = 'confirmed'
  WHERE id = (SELECT booking_id FROM escrows WHERE reference = p_reference);
  
  -- Insert status history
  INSERT INTO booking_status_history (booking_id, from_status, to_status, timestamp, notes)
  SELECT booking_id, 'pending', 'confirmed', NOW(), 
         'Payment confirmed via ' || (p_gateway_response::json->>'gateway')
  FROM escrows
  WHERE reference = p_reference;
END;
$$ LANGUAGE plpgsql;
```

Then call from TypeScript:
```typescript
await supabase.rpc('update_booking_and_escrow', {
  p_reference: reference,
  p_transaction_id: transactionId,
  p_gateway_response: JSON.stringify({ gateway, amount, currency })
});
```

### 5. Error Handling

**Current Implementation**:
```typescript
try {
  // Process webhook
} catch (error) {
  console.error('Webhook processing error:', error);
  toast({
    title: "Webhook Error",
    description: error instanceof Error ? error.message : "Failed to process payment callback",
    variant: "destructive"
  });
}
```

**Pros**:
- ✅ Catches all errors
- ✅ User-friendly error messages
- ✅ Logs to console for debugging

**Cons**:
- ⚠️ No error categorization
- ⚠️ No retry mechanism
- ⚠️ No alerting for critical errors

**Recommendations**:

1. **Categorize Errors**:
   ```typescript
   class WebhookError extends Error {
     constructor(
       message: string,
       public code: string,
       public retryable: boolean = false
     ) {
       super(message);
     }
   }
   
   // Usage
   if (!escrow) {
     throw new WebhookError(
       'Escrow not found',
       'ESCROW_NOT_FOUND',
       false // Not retryable
     );
   }
   ```

2. **Implement Retry Logic**:
   ```typescript
   const processWithRetry = async (fn: () => Promise<void>, maxRetries = 3) => {
     for (let i = 0; i < maxRetries; i++) {
       try {
         await fn();
         return;
       } catch (error) {
         if (i === maxRetries - 1 || !(error as WebhookError).retryable) {
           throw error;
         }
         await sleep(1000 * Math.pow(2, i)); // Exponential backoff
       }
     }
   };
   ```

3. **Add Error Monitoring**:
   ```typescript
   import * as Sentry from '@sentry/react';
   
   catch (error) {
     Sentry.captureException(error, {
       tags: {
         component: 'webhook',
         gateway: gateway
       },
       extra: {
         reference: reference,
         amount: amount
       }
     });
   }
   ```

### 6. Type Safety

**Current Approach**:
```typescript
const escrowClient: any = supabase;
const escrowResult: any = await escrowClient.from('escrows').select('*');
```

**Issue**: Uses `any` types to bypass TypeScript errors

**Why**: New tables not in generated Supabase types yet

**Solution**: After migration, regenerate types:
```bash
supabase gen types typescript --local > src/integrations/supabase/types.ts
```

Then update code:
```typescript
import { Database } from '@/integrations/supabase/types';

const { data: escrow } = await supabase
  .from('escrows')
  .select('*')
  .eq('reference', reference)
  .single();
```

## Security Checklist

- [x] Rate limiting implemented
- [x] Payment verification with provider API
- [ ] Webhook signature verification (Paystack only)
- [ ] Replay attack prevention
- [ ] IP whitelist (M-Pesa)
- [ ] Amount validation from database
- [ ] Database transactions for atomic updates
- [ ] Error monitoring and alerting
- [ ] Audit logging
- [ ] Input sanitization

## Performance Considerations

### Current Performance

**Estimated Response Time**:
- Rate limit check: ~1ms
- Payment verification API call: ~500-1000ms
- Database updates (4 queries): ~100-200ms
- **Total**: ~600-1200ms

**Bottlenecks**:
1. Payment provider API calls (network latency)
2. Multiple database queries (not batched)

### Optimization Recommendations

1. **Batch Database Operations**:
   ```typescript
   // Instead of 4 separate queries, use RPC function
   await supabase.rpc('update_booking_and_escrow', {...});
   // Reduces to 1 query
   ```

2. **Cache Payment Verifications**:
   ```typescript
   const verificationCache = new Map<string, any>();
   
   const getCachedVerification = async (reference: string) => {
     if (verificationCache.has(reference)) {
       return verificationCache.get(reference);
     }
     const result = await paystackService.verifyPayment(reference);
     verificationCache.set(reference, result);
     return result;
   };
   ```

3. **Async Logging**:
   ```typescript
   // Don't await logging
   supabase.from('payment_events').insert([{...}]); // Fire and forget
   ```

## Testing Recommendations

### Unit Tests

```typescript
describe('Webhook Handler', () => {
  it('should check rate limit correctly', () => {
    expect(checkRateLimit('paystack')).toBe(true);
    // ... 10 more calls
    expect(checkRateLimit('paystack')).toBe(false);
  });
  
  it('should handle Paystack webhook', async () => {
    const result = await handlePaystackWebhook('TEST-REF');
    expect(result).toBeDefined();
  });
});
```

### Integration Tests

```typescript
describe('Webhook Integration', () => {
  it('should update booking and escrow on success', async () => {
    // Create test booking and escrow
    // Simulate webhook
    // Verify database updates
  });
});
```

### Load Tests

```bash
# Test rate limiting under load
ab -n 100 -c 10 http://localhost:8087/webhooks?gateway=paystack&reference=TEST
```

## Deployment Checklist

Before deploying to production:

- [ ] Apply database migration
- [ ] Regenerate Supabase types
- [ ] Update environment variables
- [ ] Configure webhook URLs in provider dashboards
- [ ] Set up error monitoring (Sentry)
- [ ] Implement Redis-based rate limiting
- [ ] Add webhook signature verification
- [ ] Add replay attack prevention
- [ ] Set up alerting for failed webhooks

- [ ] Load test webhook endpoints
- [ ] Document webhook URLs for ops team

## Conclusion

The current webhook implementation provides a solid foundation with:
- ✅ Basic rate limiting
- ✅ Payment verification
- ✅ Database updates
- ✅ Error handling

**Priority Improvements**:
1. **High**: Add database transactions for atomic updates
2. **High**: Implement proper signature verification
3. **Medium**: Add Redis-based rate limiting for production
4. **Medium**: Implement replay attack prevention
5. **Low**: Add error monitoring and alerting

The implementation is production-ready for MVP with the high-priority improvements.

# Escrow Milestone-Based Release System

## Overview
This document describes the milestone-based escrow release system implemented for H&A Stay Hub to address the cash flow problem for property owners with long-term bookings.

## Problem
Previously, property owners had to wait until the entire guest stay was completed (e.g., 30 days) to release their escrow funds. This created significant cash flow issues for hosts relying on regular income.

## Solution
Implemented a milestone-based escrow release system that:
- **Short stays (≤7 days)**: Uses the existing single-release model
- **Long stays (>7 days)**: Automatically generates weekly milestones for fund release

## Implementation Details

### Database Schema
**File**: `supabase/migrations/20260121000001_escrow_milestones.sql`

Creates the `escrow_milestones` table with:
- `id`: Primary key
- `escrow_id`: Foreign key to escrows table
- `milestone_number`: Sequential milestone number (1, 2, 3...)
- `scheduled_date`: When milestone becomes eligible for release
- `amount`: Portion of escrow allocated to this milestone
- `currency`: Currency code
- `status`: 'pending', 'ready', 'released', 'disputed'
- `pin_hashed`: SHA-256 hashed PIN for this milestone
- `pin_released`: Boolean flag
- `released_at`: Timestamp when released
- `released_by`: User who released the milestone

### Service Layer Updates

#### EscrowService (`src/services/escrow.ts`)
Added methods:
- `generateMilestones()`: Creates milestones for long-term stays
- `getMilestones()`: Fetches all milestones for an escrow
- `updateMilestoneStatuses()`: Updates pending milestones to ready when scheduled date is reached
- `verifyAndReleaseMilestone()`: Verifies PIN and releases a specific milestone
- `getMilestoneSummary()`: Returns summary of released/pending/ready amounts

#### BookingService (`src/services/booking.ts`)
Updated `handleStatusTransition()` to:
- Auto-generate milestones when booking status changes to "confirmed"
- Only generate milestones for stays >7 days
- Fall back gracefully if milestone generation fails

### UI Components

#### EscrowMilestones (`src/components/EscrowMilestones.tsx`)
New component displaying:
- Progress bar showing released vs total amount
- Summary cards (released/ready/pending counts)
- Individual milestone cards with:
  - Scheduled date
  - Amount
  - Status badge
  - PIN entry for ready milestones
  - Release confirmation
- Security notice about PIN usage

#### EscrowPinManager (`src/components/EscrowPinManager.tsx`)
Updated to:
- Check if escrow has milestones
- Show `EscrowMilestones` component for long-term stays
- Fall back to original single-release UI for short stays

## Milestone Generation Logic

For bookings longer than 7 days:
- **7-13 days**: 2 milestones (50% each at day 7 and checkout)
- **14-20 days**: 3 milestones (33% each at day 7, 14, and checkout)
- **21+ days**: Weekly milestones (equal portions every 7 days, final at checkout)

Each milestone:
- Gets a unique 6-digit PIN generated using `crypto.getRandomValues()`
- PIN is hashed with SHA-256 and salt before storage
- PIN is sent to property owner via email/notification
- Status starts as 'pending', changes to 'ready' on scheduled date
- Owner enters PIN to release funds when ready

## Security Features
- Cryptographically secure PIN generation (not Math.random)
- SHA-256 hashing with server-side salt
- Rate limiting on PIN attempts
- Each milestone has unique PIN
- PINs are single-use per milestone
- Audit logging for all milestone operations

## Migration Instructions

**IMPORTANT**: Never use `npx supabase db reset` - this will delete all production data.

To apply the milestone migration:

1. **Via Supabase Dashboard**:
   - Go to https://supabase.com/dashboard
   - Navigate to your project
   - Go to SQL Editor
   - Copy and paste the contents of `supabase/migrations/20260121000001_escrow_milestones.sql`
   - Execute the SQL

2. **Via CLI** (if migration history is clean):
   ```bash
   npx supabase db push
   ```

If you encounter migration conflicts, use the SQL Editor method above.

## Testing

Test scenarios:
1. Create a booking for 3 days → should use single-release model
2. Create a booking for 10 days → should generate 2 milestones
3. Create a booking for 30 days → should generate 5 milestones (weekly)
4. Verify milestone status changes from pending to ready on scheduled date
5. Test PIN verification and milestone release
6. Verify escrow status changes to 'released' when all milestones are released

## Future Enhancements
- Add milestone release notifications (email/in-app)
- Implement automatic milestone status updates via cron job
- Add milestone dispute handling
- Create admin dashboard for milestone oversight
- Add milestone release analytics

## Files Modified
- `supabase/migrations/20260121000001_escrow_milestones.sql` (new)
- `src/services/escrow.ts` (updated)
- `src/services/booking.ts` (updated)
- `src/components/EscrowMilestones.tsx` (new)
- `src/components/EscrowPinManager.tsx` (updated)

## Notes
- TypeScript errors will persist until migration is applied and types are regenerated
- The system gracefully falls back to single-release if milestones table doesn't exist
- Migration file is safe to apply - it only adds a new table, doesn't modify existing data

# Performance Optimization Guide

## Overview

This guide documents the performance optimizations implemented across the H&A Stay Hub platform to ensure fast load times, smooth animations, and efficient resource usage.

## Implemented Optimizations

### 1. Lazy Loading (Requirement 10.4)

Components and images are loaded only when needed, reducing initial bundle size and improving load times.

#### Lazy-Loaded Components

**LazyLoad Wrapper**:
```tsx
import { LazyLoad, lazy } from '@/components/LazyLoad';

// Lazy load a component
const HeavyComponent = lazy(() => import('@/components/HeavyComponent'));

// Use with Suspense boundary
<LazyLoad fallback={<Skeleton />}>
  <HeavyComponent />
</LazyLoad>
```

**Location**: `src/components/LazyLoad.tsx`

#### Lazy-Loaded Images

**OptimizedImage Component**:
```tsx
import { OptimizedImage } from '@/components/OptimizedImage';

<OptimizedImage
  src="/images/property.jpg"
  alt="Property image"
  placeholder="/images/property-thumb.jpg"
  blurDataURL="data:image/jpeg;base64,..."
  className="w-full h-64 object-cover"
/>
```

**Features**:
- Intersection Observer for viewport detection
- Blur-up placeholder support
- Automatic lazy loading
- Smooth fade-in transition
- Fallback handling

**Location**: `src/components/OptimizedImage.tsx`

### 2. Intersection Observer (Requirement 10.4)

Scroll-triggered animations use Intersection Observer for better performance.

**Hook Usage**:
```tsx
import { useIntersectionObserver } from '@/hooks/use-intersection-observer';

const { ref, isVisible } = useIntersectionObserver({
  threshold: 0.1,
  rootMargin: '50px',
  freezeOnceVisible: true,
});

<div 
  ref={ref}
  className={cn(
    'transition-opacity duration-300',
    isVisible ? 'opacity-100' : 'opacity-0'
  )}
>
  Content
</div>
```

**Configuration**:
- `threshold`: 0.1 (10% of element must be visible)
- `rootMargin`: '50px' (trigger 50px before entering viewport)
- `freezeOnceVisible`: true (stop observing after first visibility)

**Location**: `src/hooks/use-intersection-observer.tsx`

### 3. CSS Transform Animations (Requirement 10.2)

All animations use CSS transforms for GPU acceleration and 60fps performance.

**Optimized Properties**:
- âœ“ `transform` (translate, scale, rotate)
- âœ“ `opacity`
- âœ— Avoid: `top`, `left`, `width`, `height`, `margin`, `padding`

**Examples**:
```css
/* Good - GPU accelerated */
.element {
  transform: translateY(20px);
  opacity: 0;
  transition: transform 300ms, opacity 300ms;
}

/* Bad - causes layout recalculation */
.element {
  top: 20px;
  opacity: 0;
  transition: top 300ms, opacity 300ms;
}
```

### 4. Reduced Motion Support (Requirement 10.5)

Respects user's motion preferences for accessibility and performance.

**Implementation**:
```css
@media (prefers-reduced-motion: reduce) {
  *,
  *::before,
  *::after {
    animation-duration: 0.01ms !important;
    animation-iteration-count: 1 !important;
    transition-duration: 0.01ms !important;
    scroll-behavior: auto !important;
  }
}
```

**Hook**:
```tsx
import { useReducedMotion } from '@/hooks/use-reduced-motion';

const prefersReducedMotion = useReducedMotion();

// Conditionally apply animations
<div className={cn(
  !prefersReducedMotion && 'animate-fade-in'
)}>
  Content
</div>
```

**Location**: `src/hooks/use-reduced-motion.tsx`, `src/index.css`

### 5. Will-Change Optimization (Requirement 10.5)

The `will-change` property is applied only during active animations to avoid performance issues.

**Utility Function**:
```tsx
import { optimizeWillChange } from '@/lib/performance';

// Apply will-change before animation
const element = document.querySelector('.animated');
optimizeWillChange(element, ['transform', 'opacity'], 300);
```

**Automatic Application**:
```tsx
// In Logo component
className={cn(
  interactive && "hover:will-change-transform"
)}
```

**Best Practices**:
- Only use during animations
- Remove after animation completes
- Limit to 2-3 properties max
- Don't apply to many elements simultaneously

### 6. Image Optimization (Requirement 10.3)

Images are optimized with blur-up placeholders and lazy loading.

**Blur-Up Technique**:
1. Show tiny blurred placeholder (< 1KB)
2. Load full image in background
3. Fade in full image when loaded

**Implementation**:
```tsx
<OptimizedImage
  src="/images/hero.jpg"
  alt="Hero image"
  blurDataURL="data:image/jpeg;base64,/9j/4AAQSkZJRg..."
  className="w-full h-screen object-cover"
/>
```

**Recommended Formats**:
- WebP with JPEG fallback
- AVIF for modern browsers
- SVG for icons and logos

### 7. Code Splitting

Large components are split into separate chunks for faster initial load.

**Route-Based Splitting**:
```tsx
// Already implemented in React Router
const Dashboard = lazy(() => import('@/pages/Dashboard'));
const PropertyDetail = lazy(() => import('@/pages/PropertyDetail'));
```

**Component-Based Splitting**:
```tsx
// Heavy components loaded on demand
const EarningsAnalytics = lazy(() => import('@/components/EarningsAnalytics'));
const BookingStatusManager = lazy(() => import('@/components/BookingStatusManager'));
```

> âš ï¸ **Critical: Do not use `manualChunks` to split React-dependent libraries**
>
> The project previously used `manualChunks` in `vite.config.ts` to split `react-hook-form`, `zod`, and Radix UI into separate chunks. This caused a **P0 production outage** â€” a Rollup cross-chunk Temporal Dead Zone (TDZ) crash where `react-hook-form` called `React.createContext()` before the React chunk had initialized, crashing every page with a white blank screen.
>
> **The current configuration intentionally omits `manualChunks`** and relies on Vite's built-in splitting. If you need to re-introduce manual chunking, ensure React and all libraries that call React APIs at module-evaluation time are in the same chunk. See [`INCIDENT_PROD_TDZ_CRASH_2026-06-15.md`](./INCIDENT_PROD_TDZ_CRASH_2026-06-15.md) for full details.

### 8. Performance Utilities

**Location**: `src/lib/performance.ts`

#### Debounce
Limits function execution rate for expensive operations.

```tsx
import { debounce } from '@/lib/performance';

const handleSearch = debounce((query: string) => {
  // Expensive search operation
  searchProperties(query);
}, 300);
```

#### Throttle
Ensures function executes at most once per time period.

```tsx
import { throttle } from '@/lib/performance';

const handleScroll = throttle(() => {
  // Scroll handler
  updateScrollPosition();
}, 100);
```

#### Request Idle Callback
Executes non-critical work during browser idle time.

```tsx
import { requestIdleCallback } from '@/lib/performance';

requestIdleCallback(() => {
  // Non-critical analytics
  trackPageView();
}, { timeout: 2000 });
```

#### Batch DOM Operations
Prevents layout thrashing by batching reads and writes.

```tsx
import { batchDOMOperations } from '@/lib/performance';

const elements = document.querySelectorAll('.card');

batchDOMOperations(
  // Reads
  [
    () => elements.forEach(el => el.getBoundingClientRect()),
  ],
  // Writes
  [
    () => elements.forEach(el => el.style.transform = 'translateY(0)'),
  ]
);
```

#### Optimized Scroll Handler
Uses passive event listener and requestAnimationFrame.

```tsx
import { createOptimizedScrollHandler } from '@/lib/performance';

const cleanup = createOptimizedScrollHandler((scrollY) => {
  // Handle scroll
  updateNavigation(scrollY);
});

// Cleanup on unmount
return cleanup;
```

## Performance Metrics

### Target Metrics (Requirements 10.1, 10.2)

- **First Contentful Paint (FCP)**: < 1.5s
- **Largest Contentful Paint (LCP)**: < 2.5s
- **Time to Interactive (TTI)**: < 3.5s
- **Cumulative Layout Shift (CLS)**: < 0.1
- **First Input Delay (FID)**: < 100ms
- **Frame Rate**: 60fps for all animations

### Measuring Performance

**Get Performance Metrics**:
```tsx
import { getPerformanceMetrics } from '@/lib/performance';

const metrics = getPerformanceMetrics();
console.log('TTFB:', metrics.ttfb);
console.log('FCP:', metrics.fcp);
console.log('Total Load Time:', metrics.totalLoadTime);
```

**Measure Function Performance**:
```tsx
import { measurePerformance } from '@/lib/performance';

const result = await measurePerformance('fetchProperties', async () => {
  return await fetchProperties();
});

// Check performance entries
const measures = performance.getEntriesByName('fetchProperties');
console.log('Duration:', measures[0].duration);
```

## Best Practices

### 1. Component Optimization

**Use React.memo for expensive components**:
```tsx
export const ExpensiveComponent = React.memo(({ data }) => {
  // Component logic
}, (prevProps, nextProps) => {
  // Custom comparison
  return prevProps.data.id === nextProps.data.id;
});
```

**Use useMemo for expensive calculations**:
```tsx
const sortedData = useMemo(() => {
  return data.sort((a, b) => a.price - b.price);
}, [data]);
```

**Use useCallback for event handlers**:
```tsx
const handleClick = useCallback(() => {
  // Handler logic
}, [dependencies]);
```

### 2. Image Optimization

**Always specify dimensions**:
```tsx
<OptimizedImage
  src="/image.jpg"
  alt="Description"
  width={800}
  height={600}
  className="w-full h-auto"
/>
```

**Use appropriate formats**:
- Photos: WebP/JPEG
- Graphics: WebP/PNG
- Icons: SVG
- Animations: CSS/SVG (avoid GIF)

**Implement responsive images**:
```tsx
<picture>
  <source srcSet="/image-large.webp" media="(min-width: 1024px)" />
  <source srcSet="/image-medium.webp" media="(min-width: 768px)" />
  <img src="/image-small.webp" alt="Description" />
</picture>
```

### 3. Animation Optimization

**Use CSS animations over JavaScript**:
```css
/* Preferred */
.element {
  animation: fadeIn 300ms ease-out;
}

@keyframes fadeIn {
  from { opacity: 0; }
  to { opacity: 1; }
}
```

**Limit concurrent animations**:
- Maximum 3-4 elements animating simultaneously
- Stagger animations for better performance
- Use `animation-delay` for sequencing

**Optimize animation properties**:
```tsx
// Good - GPU accelerated
transform: translateX(100px) scale(1.1);
opacity: 0.5;

// Bad - causes reflow
left: 100px;
width: 200px;
```

### 4. Bundle Optimization

**Analyze bundle size**:
```bash
npm run build
# Check dist/ folder sizes
```

**Code splitting strategies**:
- Route-based splitting (automatic with React Router)
- Component-based splitting (lazy load heavy components)
- Vendor splitting (separate chunk for node_modules)

**Tree shaking**:
- Use ES6 imports (not CommonJS)
- Import only what you need
- Avoid barrel exports for large libraries

### 5. Network Optimization

**Preload critical resources**:
```tsx
import { preloadResources } from '@/lib/performance';

// Preload hero image
preloadResources(['/images/hero.jpg'], 'image');

// Preload fonts
preloadResources(['/fonts/inter.woff2'], 'font');
```

**Use CDN for static assets**:
- Images
- Fonts
- Third-party libraries

**Implement caching strategies**:
```tsx
// React Query with caching
const { data } = useQuery('properties', fetchProperties, {
  staleTime: 5 * 60 * 1000, // 5 minutes
  cacheTime: 10 * 60 * 1000, // 10 minutes
});
```

## Testing Performance

### Browser DevTools

**Chrome DevTools**:
1. Open DevTools (F12)
2. Go to Performance tab
3. Click Record
4. Interact with page
5. Stop recording
6. Analyze flame chart

**Lighthouse Audit**:
1. Open DevTools (F12)
2. Go to Lighthouse tab
3. Select categories (Performance, Accessibility, Best Practices)
4. Click "Generate report"
5. Review scores and recommendations

### Performance Monitoring

**Web Vitals**:
```tsx
import { getCLS, getFID, getFCP, getLCP, getTTFB } from 'web-vitals';

getCLS(console.log);
getFID(console.log);
getFCP(console.log);
getLCP(console.log);
getTTFB(console.log);
```

**Custom Metrics**:
```tsx
// Mark important events
performance.mark('hero-loaded');
performance.mark('dashboard-rendered');

// Measure between marks
performance.measure('hero-to-dashboard', 'hero-loaded', 'dashboard-rendered');

// Get measurements
const measures = performance.getEntriesByType('measure');
```

## Troubleshooting

### Issue: Slow initial load
**Solutions**:
- Implement code splitting
- Lazy load below-the-fold content
- Optimize images (compress, use WebP)
- Minimize JavaScript bundle
- Use CDN for static assets

### Issue: Janky animations
**Solutions**:
- Use CSS transforms instead of position properties
- Limit concurrent animations
- Apply will-change only during animations
- Check for layout thrashing
- Use requestAnimationFrame for JS animations

### Issue: High memory usage
**Solutions**:
- Remove will-change after animations
- Unsubscribe from event listeners
- Clear intervals and timeouts
- Implement virtual scrolling for long lists
- Use React.memo to prevent unnecessary re-renders

### Issue: Slow scroll performance
**Solutions**:
- Use passive event listeners
- Throttle scroll handlers
- Use Intersection Observer instead of scroll events
- Avoid expensive calculations in scroll handlers
- Implement virtual scrolling

## Requirements Coverage

This implementation satisfies:

- **10.1**: Logo renders within 100ms âœ“
- **10.2**: CSS transforms used for 60fps performance âœ“
- **10.3**: Images use blur-up placeholders âœ“
- **10.4**: Dashboard components lazy loaded below fold âœ“
- **10.5**: Will-change optimized, reduced motion supported âœ“

# Accessibility Guide

## Overview

This guide documents the accessibility features implemented across the H&A Stay Hub platform to ensure an inclusive experience for all users, including those using assistive technologies.

## Implemented Features

### 1. Visible Focus Indicators (Requirement 9.2)

All interactive elements have visible focus indicators with a 2px outline.

**Implementation**:
```css
*:focus-visible {
  outline: 2px solid hsl(var(--primary));
  outline-offset: 2px;
  border-radius: 4px;
}
```

**Affected Elements**:
- Links
- Buttons
- Form inputs
- Interactive icons
- Navigation items

**Testing**: Press Tab to navigate through the page and verify all interactive elements show a clear blue outline.

### 2. Keyboard Navigation (Requirement 9.5)

Full keyboard navigation support with logical tab order.

**Key Features**:
- Tab: Move forward through interactive elements
- Shift+Tab: Move backward through interactive elements
- Enter: Activate buttons and links
- Space: Activate buttons
- Escape: Close modals and menus

**Skip to Main Content**:
A "Skip to main content" link appears when focused, allowing keyboard users to bypass navigation.

**Location**: `src/components/accessibility/SkipToMain.tsx`

**Usage**:
```tsx
import { SkipToMain } from '@/components/accessibility';

// In App.tsx
<SkipToMain />
```

### 3. Logo Accessibility (Requirements 9.1, 9.3, 9.4)

The Logo component includes comprehensive accessibility features.

**Features**:
- **ARIA Label**: "H&A Stay Hub logo, navigate to home page"
- **Keyboard Accessible**: Enter key triggers navigation
- **Screen Reader Support**: Announces purpose and destination
- **Minimum Touch Target**: 44x44px on mobile

**Implementation**:
```tsx
<Logo 
  size="lg" 
  variant="gradient" 
  interactive
  aria-label="H&A Stay Hub logo, navigate to home page"
/>
```

**Location**: `src/components/ui/logo.tsx`

### 4. Screen Reader Support (Requirement 9.4)

Comprehensive screen reader support throughout the application.

**Components**:

#### ScreenReaderOnly
Renders content visible only to screen readers.

```tsx
import { ScreenReaderOnly } from '@/components/accessibility';

<ScreenReaderOnly>
  Additional context for screen readers
</ScreenReaderOnly>
```

#### LiveRegion
Announces dynamic content changes to screen readers.

```tsx
import { LiveRegion } from '@/components/accessibility';

<LiveRegion 
  message="Property added to favorites" 
  politeness="polite"
  clearAfter={3000}
/>
```

**Location**: `src/components/accessibility/`

### 5. ARIA Labels and Roles

All interactive elements have appropriate ARIA labels and roles.

</a>
```

**Form Inputs**:
```tsx
<input
  type="email"
  id="email"
  aria-label="Email address"
  aria-required="true"
  aria-invalid={hasError}
  aria-describedby="email-error"
/>
```

### 6. Color Contrast (Requirement 9.5)

All text meets WCAG AA standards for color contrast.

**Contrast Ratios**:
- Normal text: Minimum 4.5:1
- Large text (18px+): Minimum 3:1
- Interactive elements: Minimum 3:1

**Testing**: Use browser DevTools or online contrast checkers to verify ratios.

### 7. Touch Targets (Requirement 7.1)

<header>
  <nav>
    <!-- Navigation content -->
  </nav>
</header>

<main id="main-content">
  <!-- Main page content -->
</main>

<footer>
  <!-- Footer content -->
</footer>
```

### 9. Form Accessibility

All forms include proper labels, error messages, and validation feedback.

**Best Practices**:
```tsx
<div>
  <label htmlFor="email">Email Address</label>
  <input
    type="email"
    id="email"
    name="email"
    aria-required="true"
    aria-invalid={hasError}
    aria-describedby="email-error"
  />
  {hasError && (
    <span id="email-error" role="alert">
      Please enter a valid email address
    </span>
  )}
</div>
```

### 10. Modal Accessibility

Modals trap focus and can be closed with Escape key.

**Features**:
- Focus trap: Tab cycles through modal elements only
- Escape key: Closes modal
- Focus restoration: Returns focus to trigger element
- ARIA attributes: role="dialog", aria-modal="true"

**Implementation**: Already handled by Radix UI Dialog component.

## Accessibility Components

### SkipToMain

**Location**: `src/components/accessibility/SkipToMain.tsx`

**Usage**:
```tsx
import { SkipToMain } from '@/components/accessibility';

<SkipToMain />
```

**Behavior**:
- Hidden by default
- Visible when focused (Tab key)
- Jumps to element with id="main-content"

### ScreenReaderOnly

**Purpose**: Provides content visible only to screen readers.

**Location**: `src/components/accessibility/ScreenReaderOnly.tsx`

**Usage**:
```tsx
import { ScreenReaderOnly } from '@/components/accessibility';

<button>
  <Icon />
  <ScreenReaderOnly>Delete item</ScreenReaderOnly>
</button>
```

### LiveRegion

**Purpose**: Announces dynamic content changes to screen readers.

**Location**: `src/components/accessibility/LiveRegion.tsx`

**Usage**:
```tsx
import { LiveRegion } from '@/components/accessibility';

const [message, setMessage] = useState('');

// When something happens
setMessage('Item added to cart');

<LiveRegion 
  message={message} 
  politeness="polite"
  clearAfter={3000}
/>
```

**Props**:

## [Unreleased]

### Fixed

#### P0 Production Outage â€” White Blank Page / TDZ Crash (2026-06-15)
- **Bug**: All pages on `hna.africa` rendered as a white blank page with `Uncaught ReferenceError: Cannot access 'C' before initialization` at `forms-B3HCCH5z.js:1:1806`
- **Type**: Rollup cross-chunk Temporal Dead Zone (TDZ) initialization error
- **Root cause**: `vite.config.ts` `manualChunks` config assigned `react-hook-form` to a `forms` chunk while React itself landed in `vendor`. Because `react-hook-form` calls `React.createContext()` at module evaluation time, the `forms` chunk crashed when it ran before `vendor` had initialized React.
- **Fix**: Removed `manualChunks` entirely from `vite.config.ts` â€” Vite's default code-splitting correctly handles cross-chunk initialization order.
- **Commits**: `63d8cdc` (intermediate), `174dba2` (final fix)
- **Incident doc**: [`docs/INCIDENT_PROD_TDZ_CRASH_2026-06-15.md`](./INCIDENT_PROD_TDZ_CRASH_2026-06-15.md)

  return (
    <div className="min-h-screen">
      <Navigation />
      <main>
        {/* Page content */}
      </main>
      <Footer />
    </div>
  );
};
```

- **Logo Spacing**: `gap-6` (24px) from surrounding elements
- **Section Spacing**: `mb-12` (48px) between main sections
- **Link Spacing**: `space-y-3` (12px) between links

### Typography
- **Category Headers**: Uppercase, tracking-wide, font-semibold
- **Links**: text-sm (14px)
- **Copyright**: text-sm (14px)

### Responsive Behavior

#### Mobile (< 768px)
- Links grid: 2 columns
- Logo and copyright: Stacked vertically, centered
- Social icons: Centered below logo
- Language/Currency: Centered, wrapped
- Legal links: Centered, wrapped

#### Desktop (≥ 768px)
- Links grid: 4 columns
- Logo and copyright: Horizontal, left-aligned
- Social icons: Right-aligned
- Language/Currency: Right-aligned
- Legal links: Centered

## Accessibility Features

### ARIA Labels
All social media links have descriptive aria-labels:
```tsx
<a href="#" aria-label="Follow us on Facebook">
  <Facebook className="h-5 w-5" />
</a>
```

### Keyboard Navigation
- All links and buttons are keyboard accessible
- Focus indicators visible (inherited from global styles)
- Logical tab order maintained

### Screen Reader Support
- Semantic HTML structure with `<footer>` element
- Proper heading hierarchy
- Descriptive link text and aria-labels

## Customization

### Adding New Link Categories

```tsx
const footerLinks = {
  Company: ["About Us", "Careers", "Press", "Blog"],
  Support: ["Help Center", "Safety Information", "Cancellation Policy", "Contact Us"],
  Hosting: ["Become a Host", "Host Resources", "Community Forum", "Hosting Responsibly"],
  Discover: ["Trust & Safety", "Travel Credits", "Gift Cards", "Mobile App"],
  // Add new category
  Legal: ["Privacy Policy", "Terms of Service", "Cookie Policy"],
};
```

### Changing Logo Variant

```tsx
<Logo 
  size="sm" 
  variant="primary"  // Change from "gradient" to "primary", "white", or "dark"
  interactive
/>
```

### Adding More Social Icons

```tsx
import { Youtube } from "lucide-react";

// In the social icons section
<a
  href="#"
  className={cn(
    "text-muted-foreground hover:text-primary",
    "transition-colors duration-150 ease-in-out",
    "active:scale-95 transition-transform duration-100"
  )}
  aria-label="Subscribe on YouTube"
>
  <Youtube className="h-5 w-5" />
</a>
```

## Performance Considerations

### Optimizations
1. **Static Content**: Footer content is static, no API calls
2. **CSS Transitions**: Uses GPU-accelerated transforms
3. **Minimal Re-renders**: No state management, pure component
4. **Lazy Loading**: Icons loaded from lucide-react (tree-shakeable)

### Best Practices
- Keep link lists concise (4-6 items per category)
- Use SVG icons for scalability
- Avoid heavy images in footer
- Minimize external dependencies

## Testing

3. **Language Switching**: Implement actual i18n functionality
4. **Currency Conversion**: Connect to real currency API
5. **App Store Badges**: Add iOS and Android download links
6. **Trust Badges**: Display security and payment certifications

## Troubleshooting

### Issue: Footer not displaying
**Solution**: Ensure Footer is imported and rendered in the page component.

### Issue: Logo too large/small
**Solution**: Adjust the `size` prop on the Logo component ("xs", "sm", "md", "lg", "xl").

### Issue: Spacing inconsistent
**Solution**: Verify max-width is set to 1400px and padding is py-12 px-4.

### Issue: Links not working
**Solution**: Replace `href="#"` with actual routes or external URLs.

### Issue: Social icons not aligned
**Solution**: Check flex container has `items-center` and proper gap spacing.

## Code Example: Complete Footer Integration

```tsx
import Navigation from "@/components/Navigation";
import Footer from "@/components/Footer";

const MyPage = () => {
  return (
    <div className="min-h-screen flex flex-col">
      <Navigation />
      
      {/* Main content - flex-1 pushes footer to bottom */}
      <main className="flex-1">
        <div className="container mx-auto px-4 py-8">
          {/* Your page content */}
        </div>
      </main>
      
      <Footer />
    </div>
  );
};

export default MyPage;
```

## Design Rationale

### Why bg-muted instead of bg-card?
The muted background provides better visual separation from the main content while maintaining a cohesive look with the overall design system.

### Why max-width 1400px?
This width ensures optimal readability and prevents the footer from becoming too wide on large screens, matching the dashboard and other content areas.

### Why 24px spacing for logo?
The 24px (gap-6) spacing provides comfortable visual breathing room without making the footer feel sparse, following the 8px grid system.

### Why uppercase category headers?
Uppercase headers with tracking create clear visual hierarchy and help users quickly scan footer sections.

# Loading States Implementation Guide

## Overview

This guide documents the comprehensive loading states and skeleton loader system implemented for the H&A Stay Hub platform as part of Task 7: Implement Loading States and Skeletons.

## Features Implemented

### 1. Skeleton Loader Components (Requirement 8.2)

Multiple skeleton loader components have been created to match the dashboard layout:

- **SkeletonWithShimmer**: Base skeleton with shimmer effect
- **StatCardSkeleton**: Matches dashboard stat cards
- **PropertyCardSkeleton**: Matches property listing cards
- **BookingCardSkeleton**: Matches booking list items
- **DashboardOverviewSkeleton**: Complete dashboard overview section
- **DashboardSkeleton**: Full dashboard loading state
- **PageLoadingSkeleton**: Generic page loading state

### 2. Shimmer Animation Effect (Requirement 8.3)

All skeleton loaders feature a smooth shimmer animation:
- **Duration**: 1500ms
- **Direction**: Left-to-right
- **Implementation**: CSS gradient animation with `animate-shimmer` class
- **Performance**: Uses CSS transforms for 60fps performance

```tsx
<SkeletonWithShimmer className="h-12 w-full" />
```

### 3. Logo Pulse Animation (Requirement 8.1)

The Logo component now supports a loading state with pulse animation:

```tsx
<Logo 
  size="lg" 
  variant="gradient" 
  loading={isLoading}  // Shows pulse animation when true
/>
```

**Features**:
- Subtle pulse animation (2000ms ease-in-out infinite)
- Automatically applied during page initialization
- Used in Navigation component during auth check

### 4. Button Loading State (Requirement 8.4)

The Button component includes comprehensive loading state support:

```tsx
<Button 
  loading={isSubmitting}
  onClick={handleSubmit}
>
  Submit
</Button>
```

**Features**:
- Animated loading spinner (Loader2 icon)
- Automatic disabled state when loading
- Cursor changes to "wait" indicator
- Works with all button variants (primary, secondary, outline, ghost, destructive)

### 5. Content Fade-in Transition (Requirement 8.5)

Smooth 300ms fade-in animation when content replaces skeletons:

```tsx
// Option 1: Using ContentFadeIn wrapper
<ContentFadeIn>
  {actualContent}
</ContentFadeIn>

// Option 2: Using animate-in classes directly
<div className="animate-in fade-in duration-300">
  {actualContent}
</div>
```

## Usage Examples

### Dashboard Loading Pattern

```tsx
const Dashboard = () => {
  const [loading, setLoading] = useState(true);
  
  useEffect(() => {
    loadData().then(() => setLoading(false));
  }, []);
  
  if (loading) {
    return (
      <div className="min-h-screen bg-background">
        <Navigation />
        <DashboardSkeleton />
      </div>
    );
  }
  
  return (
    <div className="min-h-screen bg-background">
      <Navigation />
      <div className="container mx-auto px-4 py-8 animate-in fade-in duration-300">
        {/* Actual content */}
      </div>
    </div>
  );
};
```

### Staggered Card Loading

```tsx
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-4 gap-6">
  {[0, 1, 2, 3].map((i) => (
    <StatCardSkeleton key={i} delay={i * 100} />
  ))}
</div>
```

### Form Submission with Loading

```tsx
const [isSubmitting, setIsSubmitting] = useState(false);

const handleSubmit = async () => {
  setIsSubmitting(true);
  try {
    await submitForm();
  } finally {
    setIsSubmitting(false);
  }
};

return (
  <form onSubmit={handleSubmit}>
    {/* Form fields */}
    <Button loading={isSubmitting} type="submit">
      {isSubmitting ? "Submitting..." : "Submit"}
    </Button>
  </form>
);
```

### Navigation with Logo Loading

```tsx
const Navigation = () => {
  const [isLoading, setIsLoading] = useState(true);
  
  useEffect(() => {
    checkAuth().then(() => setIsLoading(false));
  }, []);
  
  return (
    <nav>
      <Logo 
        size="lg" 
        variant="gradient" 
        interactive 
        loading={isLoading}
      />
    </nav>
  );
};
```

## Component API Reference

### SkeletonWithShimmer

```tsx
interface SkeletonWithShimmerProps extends React.HTMLAttributes<HTMLDivElement> {
  className?: string;
}
```

### StatCardSkeleton

```tsx
interface StatCardSkeletonProps {
  delay?: number; // Animation delay in milliseconds (default: 0)
}
```

### PropertyCardSkeleton

```tsx
interface PropertyCardSkeletonProps {
  delay?: number; // Animation delay in milliseconds (default: 0)
}
```

### Logo

```tsx
interface LogoProps {
  variant?: "default" | "gradient" | "primary" | "white" | "dark";
  size?: "sm" | "md" | "lg" | "xl" | "2xl" | "3xl";
  spacing?: "tight" | "normal" | "wide";
  showFullName?: boolean;
  interactive?: boolean;
  loading?: boolean; // NEW: Shows pulse animation
  onClick?: () => void;
}
```

### Button

```tsx
interface ButtonProps extends React.ButtonHTMLAttributes<HTMLButtonElement> {
  variant?: 'primary' | 'secondary' | 'outline' | 'ghost' | 'default' | 'destructive';
  size?: 'sm' | 'md' | 'lg' | 'icon';
  loading?: boolean; // Shows spinner and disables button
  children?: React.ReactNode;
}
```

### ContentFadeIn

```tsx
interface ContentFadeInProps extends React.HTMLAttributes<HTMLDivElement> {
  children: React.ReactNode;
  className?: string;
}
```

## Animation Specifications

### Shimmer Animation
- **Keyframe**: `translateX(-100%)` to `translateX(100%)`
- **Duration**: 1500ms
- **Timing**: linear
- **Iteration**: infinite

### Pulse Animation
- **Keyframe**: `opacity: 1` → `opacity: 0.8` → `opacity: 1`
- **Duration**: 2000ms
- **Timing**: ease-in-out
- **Iteration**: infinite

### Fade-in Animation
- **Keyframe**: `opacity: 0` to `opacity: 1`
- **Duration**: 300ms
- **Timing**: ease-in-out
- **Iteration**: once

### Button Press Feedback
- **Transform**: `scale(1)` to `scale(0.95)`
- **Duration**: 100ms
- **Timing**: ease-out
- **Trigger**: active state

## Performance Considerations

1. **CSS Transforms**: All animations use CSS transforms for GPU acceleration
2. **Will-change**: Applied only during active animations
3. **Reduced Motion**: Respects `prefers-reduced-motion` media query
4. **Lazy Loading**: Skeleton components are lightweight and render quickly
5. **Staggered Animations**: Prevent layout thrashing with controlled delays

## Accessibility

1. **ARIA Hidden**: Shimmer effects marked with `aria-hidden="true"`
2. **Loading States**: Buttons properly disabled during loading
3. **Screen Readers**: Loading states announced appropriately
4. **Focus Management**: Focus indicators maintained during loading states
5. **Keyboard Navigation**: All interactive elements remain keyboard accessible

## Testing

To test the loading states implementation:

1. **Visual Testing**: Use the LoadingStatesExample component
2. **Manual Testing**: Throttle network in DevTools to see loading states
3. **Automated Testing**: Playwright tests verify loading state transitions

```tsx
// Example test
test('should show skeleton loader while loading', async ({ page }) => {
  await page.goto('/dashboard');
  await expect(page.locator('.animate-shimmer')).toBeVisible();
  await page.waitForSelector('.animate-in.fade-in');
});
```

- **Scope**: All animations and transitions

## Components

### PageTransition Component

**Location**: `src/components/PageTransition.tsx`

Wraps page content to provide smooth fade-in transitions on route changes.

**Usage**:
```tsx
import PageTransition from '@/components/PageTransition';

<PageTransition>
  <Routes>
    <Route path="/" element={<Index />} />
    {/* other routes */}
  </Routes>
</PageTransition>
```

**Props**:
- `children`: React.ReactNode - The content to wrap
- `className?`: string - Optional additional CSS classes

**Features**:
- Automatically resets on route change
- Uses 300ms fade-in duration
- Respects reduced motion preferences

### Enhanced Dialog Components

**Location**: `src/components/ui/dialog.tsx`, `src/components/ui/alert-dialog.tsx`

**Improvements**:
1. **Modal Animation**: Scale from 95% to 100% over 250ms
2. **Elevation**: Uses `shadow-elevation-16` for proper visual hierarchy
3. **Close Button**: Active state with scale-95 feedback
4. **Duration**: Changed from 200ms to 250ms for smoother feel

**Usage**:
```tsx
import { Dialog, DialogContent, DialogHeader, DialogTitle } from '@/components/ui/dialog';

<Dialog open={isOpen} onOpenChange={setIsOpen}>
  <DialogContent>
    <DialogHeader>
      <DialogTitle>Modal Title</DialogTitle>
    </DialogHeader>
    {/* content */}
  </DialogContent>
</Dialog>
```

### Enhanced Button Component

**Location**: `src/components/ui/button.tsx`

**Features**:
- Active state: `active:scale-95` with 100ms transition
- Loading state: Displays spinner and disables interaction
- Smooth color transitions: 150ms ease-in-out

**Usage**:
```tsx
import { Button } from '@/components/ui/button';

<Button variant="primary" loading={isLoading}>
  Click Me
</Button>
```

## Global Styles

**Location**: `src/index.css`

### Interactive Element Transitions

All interactive elements (links, buttons, etc.) have smooth transitions:
- Color: 150ms ease-in-out
- Background: 150ms ease-in-out
- Border: 150ms ease-in-out
- Transform: 100ms ease-out
- Opacity: 150ms ease-in-out

### Reduced Motion Support

```css
@media (prefers-reduced-motion: reduce) {
  *,
  *::before,
  *::after {
    animation-duration: 0.01ms !important;
    animation-iteration-count: 1 !important;
    transition-duration: 0.01ms !important;
    scroll-behavior: auto !important;
  }
}
```

## Animation Configuration

**Location**: `src/lib/animations.ts`

### Presets

```typescript
export const ANIMATION_PRESETS = {
  fast: { duration: 150, easing: 'ease-out' },
  normal: { duration: 200, easing: 'ease-in-out' },
  slow: { duration: 300, easing: 'ease-in-out' },
  pageTransition: { duration: 300, easing: 'ease-in-out' },
  modal: { duration: 250, easing: 'ease-out' },
  // ... other presets
}
```

## Navigation Integration

The Navigation component already implements:
- Active route highlighting with underline animation (200ms)
- Mobile menu slide-in animation (300ms)
- Staggered menu item animations (50ms intervals)
- Smooth color transitions on hover (200ms)

**Location**: `src/components/Navigation.tsx`

## Best Practices

### 1. Use Consistent Timing
- Micro-interactions: 100-150ms
- Standard transitions: 200-300ms
- Page-level animations: 300-600ms

### 2. Respect User Preferences
- Always check for `prefers-reduced-motion`
- Provide fallbacks for older browsers
- Test with motion preferences disabled

### 3. Performance Optimization
- Use CSS transforms instead of position properties
- Apply `will-change` only during active animations
- Use `transform` and `opacity` for best performance

### 4. Accessibility
- Ensure focus indicators are visible
- Maintain keyboard navigation
- Provide alternative feedback for screen readers

## Testing

### Visual Testing
1. Navigate between pages - verify smooth fade-in
2. Open/close modals - verify scale animation
3. Click buttons - verify press feedback
4. Hover over links - verify color transitions

### Accessibility Testing
1. Enable "Reduce Motion" in OS settings
2. Verify animations are disabled/minimal
3. Test keyboard navigation
4. Test with screen reader

### Performance Testing
1. Check animation frame rate (should be 60fps)
2. Monitor CPU usage during transitions
3. Test on lower-end devices
4. Verify no layout shifts (CLS)

## Browser Support

- Chrome/Edge: Last 2 versions ✓
- Firefox: Last 2 versions ✓
- Safari: Last 2 versions ✓
- Mobile Safari: iOS 13+ ✓
- Chrome Mobile: Android 8+ ✓

## Requirements Coverage

This implementation satisfies the following requirements:

- **6.1**: Navigation remains fixed and visible during transitions ✓
- **6.2**: Page content fades in with 300ms duration ✓
- **6.3**: Active page links have color change and underline animation (200ms) ✓
- **6.4**: Buttons provide immediate feedback with scale animation (100ms) ✓
- **6.5**: Modals animate with scale effect from 95% to 100% (250ms) ✓
- **10.2**: CSS transforms used for 60fps performance ✓
- **10.5**: Reduced motion support implemented ✓

## Future Enhancements

1. **Page Transition Variants**: Different transition styles for different routes
2. **Gesture Support**: Swipe gestures for mobile navigation
3. **Loading Progress**: Visual progress indicator for slow page loads
4. **Shared Element Transitions**: Smooth transitions for elements that persist across routes

## Troubleshooting

### Issue: Transitions feel sluggish
**Solution**: Check if hardware acceleration is enabled. Ensure using `transform` and `opacity` properties.

### Issue: Animations not working
**Solution**: Verify Tailwind CSS is properly configured and animations are not disabled by reduced motion preferences.

### Issue: Modal appears instantly
**Solution**: Check that Radix UI data attributes are present and CSS animations are not overridden.

### Issue: Button feedback not visible
**Solution**: Ensure `active:scale-95` class is applied and not overridden by other styles.

# Migration Troubleshooting - "column reference does not exist"

## Problem

Error: `column "reference" does not exist` when running the migration.

This means either:
1. The migration didn't run completely
2. An old `escrows` table exists with a different schema
3. The migration failed partway through

## Solution Steps

### Step 1: Check if escrows table exists

Run this query in Supabase SQL Editor:

```sql
SELECT column_name, data_type 
FROM information_schema.columns 
WHERE table_name = 'escrows' 
ORDER BY ordinal_position;
```

**If you see columns but no `reference` column**: The old table exists and needs to be updated or dropped.

**If you see no results**: The table doesn't exist yet.

### Step 2: Check all Phase 1 tables

```sql
SELECT table_name 
FROM information_schema.tables 
WHERE table_schema = 'public' 
AND table_name IN (
  'payment_events', 
  'escrows', 
  'escrow_disputes', 
  'cancellation_requests',
  'notification_preferences',
  'notifications',
  'booking_status_history'
);
```

### Step 3: Drop existing escrows table (if needed)

⚠️ **WARNING**: This will delete all data in the escrows table!

```sql
-- Check if there's any data first
SELECT COUNT(*) FROM escrows;

-- If safe to proceed, drop the table
DROP TABLE IF EXISTS escrows CASCADE;
```

### Step 4: Re-run the migration

After dropping the old table, run the migration SQL again from:
`supabase/migrations/20250107000001_phase1_core_marketplace.sql`

### Step 5: Verify the new schema

```sql
SELECT column_name, data_type 
FROM information_schema.columns 
WHERE table_name = 'escrows' 
ORDER BY ordinal_position;
```

**Expected columns**:
- id
- property_id
- booking_id
- tenant_user_id
- amount
- currency
- status
- pin_hashed
- pin_released
- pin_attempts
- pin_locked_until
- **reference** ← This should be present
- transaction_id
- paid_at
- released_at
- gateway_response
- created_at
- updated_at

## Alternative: Alter existing table

If you want to keep existing data, you can alter the table instead:

```sql
-- Add missing columns to existing escrows table
ALTER TABLE escrows ADD COLUMN IF NOT EXISTS reference VARCHAR(100) UNIQUE;
ALTER TABLE escrows ADD COLUMN IF NOT EXISTS transaction_id VARCHAR(100);
ALTER TABLE escrows ADD COLUMN IF NOT EXISTS paid_at TIMESTAMP WITH TIME ZONE;
ALTER TABLE escrows ADD COLUMN IF NOT EXISTS released_at TIMESTAMP WITH TIME ZONE;
ALTER TABLE escrows ADD COLUMN IF NOT EXISTS gateway_response TEXT;
ALTER TABLE escrows ADD COLUMN IF NOT EXISTS pin_attempts INTEGER DEFAULT 0;
ALTER TABLE escrows ADD COLUMN IF NOT EXISTS pin_locked_until TIMESTAMP WITH TIME ZONE;

-- Update status constraint if needed
ALTER TABLE escrows DROP CONSTRAINT IF EXISTS escrows_status_check;
ALTER TABLE escrows ADD CONSTRAINT escrows_status_check 
  CHECK (status IN ('pending', 'held', 'released', 'disputed', 'failed'));

-- Add indexes
CREATE INDEX IF NOT EXISTS idx_escrows_reference ON escrows(reference);
CREATE INDEX IF NOT EXISTS idx_escrows_booking_id ON escrows(booking_id);
CREATE INDEX IF NOT EXISTS idx_escrows_status ON escrows(status);
```

## Quick Fix Script

Run this complete script to fix the escrows table:

```sql
-- Check current schema
DO $$
DECLARE
  has_reference BOOLEAN;
BEGIN
  SELECT EXISTS (
    SELECT 1 FROM information_schema.columns 
    WHERE table_name = 'escrows' AND column_name = 'reference'
  ) INTO has_reference;
  
  IF NOT has_reference THEN
    RAISE NOTICE 'Adding missing columns to escrows table...';
    
    -- Add missing columns
    ALTER TABLE escrows ADD COLUMN IF NOT EXISTS reference VARCHAR(100) UNIQUE;
    ALTER TABLE escrows ADD COLUMN IF NOT EXISTS transaction_id VARCHAR(100);
    ALTER TABLE escrows ADD COLUMN IF NOT EXISTS paid_at TIMESTAMP WITH TIME ZONE;
    ALTER TABLE escrows ADD COLUMN IF NOT EXISTS released_at TIMESTAMP WITH TIME ZONE;
    ALTER TABLE escrows ADD COLUMN IF NOT EXISTS gateway_response TEXT;
    ALTER TABLE escrows ADD COLUMN IF NOT EXISTS pin_attempts INTEGER DEFAULT 0;
    ALTER TABLE escrows ADD COLUMN IF NOT EXISTS pin_locked_until TIMESTAMP WITH TIME ZONE;
    
    -- Update status constraint
    ALTER TABLE escrows DROP CONSTRAINT IF EXISTS escrows_status_check;
    ALTER TABLE escrows ADD CONSTRAINT escrows_status_check 
      CHECK (status IN ('pending', 'held', 'released', 'disputed', 'failed'));
    
    -- Add indexes
    CREATE INDEX IF NOT EXISTS idx_escrows_reference ON escrows(reference);
    CREATE INDEX IF NOT EXISTS idx_escrows_booking_id ON escrows(booking_id);
    CREATE INDEX IF NOT EXISTS idx_escrows_status ON escrows(status);
    
    RAISE NOTICE 'Escrows table updated successfully!';
  ELSE
    RAISE NOTICE 'Escrows table already has reference column.';
  END IF;
END $$;
```

## Verification

After fixing, verify with:

```sql
-- Check escrows table structure
SELECT column_name, data_type, is_nullable
FROM information_schema.columns 
WHERE table_name = 'escrows' 
ORDER BY ordinal_position;

-- Check indexes
SELECT indexname 
FROM pg_indexes 
WHERE tablename = 'escrows';

-- Test insert
INSERT INTO escrows (
  property_id, booking_id, tenant_user_id, 
  amount, currency, status, pin_hashed, reference
)
VALUES (
  (SELECT id FROM properties LIMIT 1),
  (SELECT id FROM bookings LIMIT 1),
  (SELECT id FROM users LIMIT 1),
  100.00, 'USD', 'pending', 'test_hash', 'TEST-ESC-001'
)
RETURNING *;

-- Clean up test
DELETE FROM escrows WHERE reference = 'TEST-ESC-001';
```

## Next Steps

After fixing the escrows table:
1. ✅ Verify all columns exist
2. ✅ Verify indexes created
3. ✅ Test data insertion
4. ➡️ Continue with other Phase 1 tables
5. ➡️ Run full migration verification

   - Choose sign in or sign up tab
   - Or use demo mode to explore

2. **Complete Onboarding:**
   - After authentication, you'll be guided to onboarding
   - Select your role (Tenant, Property Owner, or Agent)
   - Complete the KYC form
   - Or skip and complete later

3. **Dashboard:**
   - If onboarding is incomplete, you'll see a banner
   - Click "Complete Profile" to finish onboarding
   - Dismiss the banner to hide it for the session

### For Developers

1. **Apply Migration:**
   ```bash
   # Apply the onboarding tracking migration
   npx supabase migration up
   ```

2. **Test the Flow:**
   ```bash
   # Start development server
   npm run dev
   
   # Navigate to http://localhost:8087/auth
   ```

3. **Check Onboarding Status:**
   ```typescript
   import { useOnboardingStatus } from '@/hooks/use-onboarding-status';
   
   const { status, getCompletionPercentage } = useOnboardingStatus();
   ```

## 🔧 Configuration

### Environment Variables
No new environment variables required. Uses existing Supabase configuration.

### Database Tables
- `user_profiles` - Extended with onboarding fields
- `onboarding_sessions` - New table for progress tracking

### Routes
- `/auth` - Unified authentication page
- `/auth?mode=signin` - Direct to sign in
- `/auth?mode=signup` - Direct to sign up
- `/onboarding` - Onboarding wizard
- `/dashboard` - Dashboard with onboarding banner

## 🐛 Known Issues

1. **TypeScript Errors:**
   - Some TypeScript errors exist due to database types not being regenerated
   - These will resolve after applying migration and regenerating types
   - Run: `npx supabase gen types typescript --local > src/types/supabase.ts`

2. **Demo Mode:**
   - Demo users store data in localStorage
   - Data persists until localStorage is cleared
   - Not suitable for production use
