## POST `/api/v1/appointment`

Book an appointment slot.

**Permission:** `AUTH` — any authenticated user

### Request Body (`application/json`)
```json
{
  "doctor_uuid": "550e8400-e29b-41d4-a716-446655440000",
  "slot_start": 1718438400,
  "slot_end": 1718439600,
  "for_self": false,
  "patient_name": "علی احمدی",
  "patient_mobile": "09120000000",
  "patient_national_code": "0012345678",
  "patient_gender": "man",
  "patient_reason": "چکاپ",
  "note": "لطفاً سریع ویزیت شوم"
}
```

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `doctor_uuid` | string (UUID) | ✅ | Doctor UUID |
| `slot_start` | integer | ✅ | Slot start (Unix timestamp) |
| `slot_end` | integer | ✅ | Slot end (Unix timestamp) |
| `for_self` | boolean | ❌ | `true` (default) = patient is the logged-in payer; `false` = booking for someone else |
| `patient_name` | string | ⚠️ | Required when `for_self=false`; otherwise filled from the payer's profile |
| `patient_mobile` | string | ⚠️ | Required when `for_self=false`; otherwise the payer's mobile |
| `patient_national_code` | string | ✅ | کد ملی بیمار — **همیشه الزامی** (هر دو حالت `for_self`). باید ۱۰ رقم معتبر باشد (`isValidIranNationalCode`)؛ ارقام فارسی به انگلیسی تبدیل می‌شوند |
| `patient_gender` | string | ✅ | جنسیت بیمار — **همیشه الزامی**. ورودی `man`/`male` یا `woman`/`female` پذیرفته می‌شود و به فرمِ متعارف `man`/`woman` ذخیره می‌گردد |
| `patient_reason` | string | ❌ | Reason for visit |
| `note` | string | ❌ | Patient note |
| `city_id` | integer | ❌ | شناسه‌ی شهرِ دامنه‌ی جاری (از `city.json` سایت). برای گاردِ پورسانت نماینده: اگر شهر نماینده‌ی فعال داشته باشد، `booking_representation_id` نوبت ست می‌شود. پورسانت فقط وقتی واریز می‌شود که این نماینده با نماینده‌ی پزشک یکی باشد. خالی/ناموجود ⇒ بدون پورسانت |

> **آدرس نوبت:** آدرس (`address_id`) ارسالی نیست؛ سرور آن را از روی `location_id` همان session در برنامه‌ی هفتگی که اسلات در آن قرار دارد، خودکار تعیین و ذخیره می‌کند. در پاسخ به‌صورت `address_id` برمی‌گردد. همه‌ی مسیرهای رزرو (آنلاین `POST /api/v1/appointment`، منشی `POST /api/v1/my/appointment`، ادمین) آدرس را به همین شکل ست می‌کنند.

> **تضمین عدم رزرو دوگانه:** هر سه مسیر رزرو از `AppointmentRepository::bookAtomically()` عبور می‌کنند و یک قید یکتای دیتابیسی (`active_slot_key`) پشت آن قرار دارد؛ بنابراین حتی در شرایط رقابتی (race) فقط یک نوبتِ زنده روی هر `(doctor, slot_start)` ممکن است و درخواست بازنده `409 SLOT_TAKEN` می‌گیرد. نوبت‌های لغو/منقضی اسلات را آزاد می‌کنند (کلید `NULL`).

> **Auto-add to clinic:** هنگام تأیید نوبت، اگر آدرس نوبت متعلق به یک کلینیک باشد (`DoctorAddress.clinic_id`)، بیمار علاوه بر پرونده‌ی پزشک، به پرونده‌های آن کلینیک هم اضافه می‌شود. اگر آدرس کلینیک نداشت ولی دکتر فقط عضو یک کلینیک بود، به همان کلینیک اضافه می‌شود. هر شاخه مشروط به فعال‌بودن `patient_records`. جزئیات در `docs/api/patient.md`.

> **Payer vs patient:** the authenticated user (`user`) is always the payer; the `patient_*` fields describe who the visit is for and are stored separately. **Temporary lock:** the slot is held by the new `pending` booking for **15 minutes** (`expires_at = created_at + 900`). If payment is not completed in time, the booking is moved to `expired` and the slot is freed (see `app:cancel-expired-appointments`). An expired pending booking no longer blocks the slot even before the cron runs.
