+# PRD — Персонализированные имена beneficiaries
+
+## Цель
+Позволить каждому пользователю иметь своё персональное имя для каждого beneficiary. Custodian редактирует оригинальное имя (видно всем по умолчанию), остальные роли — своё `custom_name`.
+
+## Контекст
+Сейчас имя beneficiary хранится в `beneficiaries.name` и одинаково для всех пользователей. Нужно добавить возможность персонализации: каждый accessor (кроме custodian) может задать своё имя через `user_access.custom_name`.
+
+## User Flow
+
+### Flow 1: Custodian редактирует имя (оригинал)
+
+| # | Актор | Действие | Система | Результат |
+|---|-------|----------|---------|-----------|
+| 1 | Custodian | Открывает список beneficiaries | GET `/me/beneficiaries` | Показывает `name` из `beneficiaries` таблицы |
+| 2 | Custodian | Нажимает на beneficiary | GET `/me/beneficiaries/:id` | Открывает детали |
+| 3 | Custodian | Нажимает "Edit" | — | Открывает Edit модал |
+| 4 | Custodian | Меняет имя, нажимает "Save" | PATCH `/me/beneficiaries/:id` | Обновляет `beneficiaries.name` |
+| 5 | System | — | Сохраняет в БД | Имя обновлено для ВСЕХ |
+
+### Flow 2: Guardian/Caretaker редактирует имя (персональное)
+
+| # | Актор | Действие | Система | Результат |
+|---|-------|----------|---------|-----------|
+| 1 | Caretaker | Открывает список beneficiaries | GET `/me/beneficiaries` | Показывает `custom_name` || `name` |
+| 2 | Caretaker | Нажимает на beneficiary | GET `/me/beneficiaries/:id` | Открывает детали |
+| 3 | Caretaker | Нажимает "Edit" | — | Открывает Edit модал |
+| 4 | Caretaker | Меняет имя, нажимает "Save" | PATCH `/me/beneficiaries/:id` | Обновляет `user_access.custom_name` |
+| 5 | System | — | Сохраняет в БД | Имя видно только ЭТОМУ пользователю |
+
+### Flow 3: Отображение (все роли)
+
+| # | Актор | Действие | Система | Результат |
+|---|-------|----------|---------|-----------|
+| 1 | User | Открывает Dashboard/список | GET `/me/beneficiaries` | — |
+| 2 | System | — | Для каждого: `custom_name \|\| name` | Возвращает `displayName` |
+| 3 | User | Видит список | — | Каждый beneficiary показан с персональным именем |

+## Задачи
+
+### Backend
+
+- [x] **Migration: добавить custom_name в user_access**
+  - Путь: `backend/migrations/009_add_custom_name.sql`
+  - SQL: `ALTER TABLE user_access ADD COLUMN custom_name VARCHAR(200);`
+  - Индекс не нужен (поле не для поиска)
+
+- [x] **API: изменить GET /me/beneficiaries (список)**
+  - Файл: `backend/src/routes/beneficiaries.js`
+  - В SELECT добавить `custom_name` из `user_access`
+  - В ответе добавить поле `displayName`: `custom_name || name`
+  - Также вернуть `originalName` (из `beneficiaries.name`) для UI
+
+- [x] **API: изменить GET /me/beneficiaries/:id (детали)**
+  - Файл: `backend/src/routes/beneficiaries.js`
+  - Добавить `custom_name` из `user_access` в SELECT
+  - В ответе: `displayName`, `originalName`, `customName`
+
+- [x] **API: изменить PATCH /me/beneficiaries/:id (обновление)**
+  - Файл: `backend/src/routes/beneficiaries.js`
+  - Логика:
+    - Если `role === 'custodian'` → обновить `beneficiaries.name`
+    - Иначе → обновить `user_access.custom_name`
+  - Добавить параметр `customName` в body
+
+- [x] **Деплой миграции на сервер**
+  - SSH: `root@91.98.205.156`
+  - Путь: `/var/www/wellnuo-api/`
+  - Команда: `node run-migration.js`
+  - PM2: `pm2 restart wellnuo-api`
+
+### Frontend
+
+- [x] **Types: обновить Beneficiary interface**
+  - Файл: `types/index.ts` или где определён тип
+  - Добавить: `displayName?: string`, `originalName?: string`, `customName?: string`
+
+- [x] **API service: обновить типы ответов**
+  - Файл: `services/api.ts`
+  - Обновить интерфейсы для beneficiary endpoints
+
+- [x] **UI: список beneficiaries — показывать displayName**
+  - Файл: `app/(tabs)/index.tsx` или где рендерится список
+  - Заменить `beneficiary.name` на `beneficiary.displayName || beneficiary.name`
+
+- [x] **UI: header в BeneficiaryDetail — показывать displayName**
+  - Файл: `app/(tabs)/beneficiaries/[id]/index.tsx`
+  - Строка 378: `{beneficiary.name}` → `{beneficiary.displayName || beneficiary.name}`
+
+- [x] **UI: Edit модал — разная логика для ролей**
+  - Файл: `app/(tabs)/beneficiaries/[id]/index.tsx`
+  - Для custodian:
+    - Label: "Name"
+    - Редактирует `name` (оригинал)
+  - Для guardian/caretaker:
+    - Label: "Your name for [originalName]"
+    - Placeholder: originalName
+    - Редактирует `customName`
+  - При сохранении отправлять правильное поле
+
+- [x] **UI: MockDashboard — показывать displayName**
+  - Файл: `components/MockDashboard.tsx`
+  - Передавать `displayName` вместо `name`
+
+---
+
+## Вне scope (не делаем)
+
+- Синхронизация имён с голосовым AI (Ultravox) — будет отдельной задачей
+- Интеграция с WellNuo Lite — пока не трогаем
+- Миграция существующих данных — `custom_name` изначально NULL, fallback работает
+
+---
+
+## Чеклист верификации
+
+### Функциональность
+- [x] Custodian может редактировать оригинальное имя (`beneficiaries.name`)
+- [x] Guardian/Caretaker могут редактировать своё персональное имя (`user_access.custom_name`)
+- [x] Список beneficiaries показывает `displayName` (custom_name || name)
+- [x] Header на детальной странице показывает `displayName`
+- [x] Edit модал показывает разные labels для разных ролей
+- [x] При первом открытии (custom_name = NULL) показывается оригинальное имя
+
+### Backend
+- [x] Миграция применена без ошибок
+- [x] GET `/me/beneficiaries` возвращает `displayName`, `originalName`
+- [x] GET `/me/beneficiaries/:id` возвращает `displayName`, `originalName`, `customName`
+- [x] PATCH `/me/beneficiaries/:id` правильно определяет что обновлять по роли
+
+### Код
+- [x] Нет TypeScript ошибок (`npx tsc --noEmit`)
+- [x] Backend работает без ошибок в логах PM2
+- [x] Нет console.log в продакшн коде (кроме отладочных с `[DEBUG]`)
+
+### UI/UX
+- [x] Имена отображаются корректно во всех местах
+- [x] Edit модал понятен для обоих типов редактирования
+- [x] Нет визуальных багов
+
+### Edge Cases
+- [x] custom_name = NULL → показывается originalName
+- [x] Пустая строка custom_name = "" → считается как NULL
+- [x] Длинные имена не ломают UI
