## Implementation Steps

### Step 1: Update PRD Section 5.4

Add new subsection after the existing booking flow:

```markdown
#### Guest Booking Flow

In addition to client bookings, the system supports guest bookings for visitors without accounts.

**Guest Booking Process:**

1. **Guest Visits /booking:**
   - Views available dates/times in calendar
   - Selects preferred date and time
   - Enters contact information (name, email, phone)
   - Provides problem summary
   - Completes captcha verification
   - Submits booking request

2. **Spam Protection:**
   - Custom math-based captcha (no third-party services)
   - 1 booking request per email per day
   - 5 booking requests per IP per 24 hours

3. **Guest Booking Status:**
   - Booking enters pending queue (same as client bookings)
   - Admin receives notification with guest contact info
   - Guest receives email confirmation

4. **Admin Reviews Guest Booking:**
   - Guest bookings appear in pending queue with "Guest" indicator
   - Admin sees guest name, email, phone
   - Same approval/rejection workflow as client bookings

5. **Guest Notifications:**
   - Confirmation email on submission
   - Approval email with calendar file on approval
   - Rejection email with reason on rejection

**Guest vs Client Comparison:**

| Feature | Client Booking | Guest Booking |
|---------|---------------|---------------|
| Account Required | Yes | No |
| 1-per-day Limit | By user_id | By email |
| Contact Info | From user profile | Entered at booking |
| Email Notifications | To user email | To guest_email |
| View Past Bookings | In dashboard | N/A |
| Captcha | Not required | Required |

**Note:** Logged-in users visiting `/booking` are redirected to the client booking page.
```

### Step 2: Update PRD Database Schema Section

Add to Section 16.1 (Database Schema Overview):

```markdown
2. **consultations (bookings)**
   - id, user_id (nullable for guests), guest_name, guest_email, guest_phone, booking_date, booking_time, duration (45 min), problem_summary, consultation_type (free/paid), payment_amount, payment_status (pending/received), status (pending/approved/rejected/completed/no-show/cancelled), admin_notes, created_at, updated_at
```

### Step 3: Update PRD Email Section

Add to Section 8.2 (Email Templates):

```markdown
**Guest Emails:**
1. **Guest Booking Confirmation** - Request submitted successfully
2. **Guest Booking Approved** - With consultation details and calendar file
3. **Guest Booking Rejected** - With reason (if provided)
```

### Step 4: Update PRD Change Log

Add entry to Section 18 (Change Log):

```markdown
| 1.2 | [Date] | Added guest booking functionality: public booking form at /booking, custom captcha, 1-per-day limit, guest email notifications, admin guest booking management | Development Team |
```

### Step 5: Update Architecture Documentation

Add to docs/architecture.md Services section:

```markdown
### CaptchaService

Located at `app/Services/CaptchaService.php`.

Provides custom math-based captcha for guest booking spam protection:
- `generate()` - Creates new captcha question, stores answer in session
- `validate($answer)` - Checks if provided answer matches stored answer
- `clear()` - Removes captcha from session after successful validation

No external dependencies (no Google reCAPTCHA, no Cloudflare Turnstile).
```

### Step 6: Mark Epic as Complete

Update `docs/epics/epic-11-guest-booking.md`:

Change all Definition of Done items to checked:
```markdown
