- Прайс-лист: дропдаун «Мои прайсы» (подключённые прайсы + «Все прайсы»),
  выбор фильтрует каталог по price_list_id; один прайс — выбирается сам
- Загрузить: показывает список подключённых прайсов и качает их

+Полная инструкция по установке Gitea: в репозитории `source` → `docs/gitea/`.
+
+Клиент при старте (`ElectroPharmacy_Load`) вызывает Gitea API:
+
+`GET {UpdateCheckBaseUrl}/api/v1/repos/{UpdateRepo}/releases/latest`
+
+Настройки (можно сменить без пересборки через user settings):

+| `UpdateCheckBaseUrl` | `https://git.24pharmdata.ru` |
+| `UpdateRepo` | `pharmdata/elfisa-pharmacy` |
+| `UpdateApiToken` | пусто (нужен для private releases) |
+
+## Регламент релиза
+
+1. Поднять `AssemblyVersion` / `AssemblyFileVersion` в `Properties/AssemblyInfo.cs`.
+2. `git tag vX.Y.Z && git push gitea master --tags`
+3. `powershell -File dist\build-release.ps1`
+4. Gitea → Releases → New Release → прикрепить ZIP.
+
+Старый клиент с меньшей версией увидит модалку «Доступно новое обновление» и не пустит в работу.

+# ЭльФиСА — кросс-платформенный клиент (Avalonia)
+
+Порт десктопного клиента с WinForms на **Avalonia UI** (.NET 8) —
+работает на **Windows, macOS и Linux** из одного кода. Начат как замена
+WinForms-версии (которая только под Windows).
+
+## Что уже готово (фундамент + эталонный экран)
+- **Elfisa.Core** — переносимая бизнес-логика (без UI): `ApiClient`
+  (логин, отчёт покупателя, ИИ-отчёт), DTO, `AppConfig`, `Session`.
+- **Дизайн-система** в фирменной бирюзе (#0F766E): светлая/тёмная тема,
+  стили кнопок, полей, карточек, таблицы, сайдбара (`Styles/Elfisa.axaml`).
+- **Экран входа** (`LoginView`) — реальная авторизация через `/auth/login`.
+- **Шелл** (`ShellView`) — сайдбар-навигация + карточка пользователя + выход.
+- **Отчёты** (`ReportsView`) — ПОЛНОСТЬЮ рабочий эталонный раздел:
+  период, 4 типа отчёта (агрегация как в WinForms), авто-загрузка,
+  свободный **ИИ-запрос → Word/Excel** (через `/ai`), таблица с динамическими
+  колонками. Данные скоупятся по JWT — только заказы этого покупателя.
+- Заглушки остальных разделов (Прайс-лист, Заказы, Накладные, Отправить,
+  Отказы, Справочник).
+
+## Архитектура
+MVVM (CommunityToolkit.Mvvm) + ViewLocator (VM → View по имени).
+```
+Program → App → MainWindow(RootViewModel)
+  RootViewModel: LoginViewModel  ⇄  ShellViewModel
+  ShellViewModel.CurrentPage: ReportsViewModel | PlaceholderPageViewModel | …
+```
+Вся сетевая логика — в `Elfisa.Core` (переиспользуется и десктопом, и
+будущим мобильным/веб-клиентом Avalonia).
+
+## Запуск
+```bash
+dotnet run --project src/Elfisa.Avalonia
+```
+Dev-автологин (удобно при разработке — минуя экран входа):
+```bash
+# Windows PowerShell
+$env:ELF_DEV_USER="user@example.com"; $env:ELF_DEV_PASS="***"; dotnet run --project src/Elfisa.Avalonia
+```
+Переопределение адресов (по умолчанию https://24pharmdata.ru и .../ai):
+`ELF_API_BASE_URL`, `ELF_AI_BASE_URL`.
+
+Сборка под конкретную ОС:
+```bash
+dotnet publish src/Elfisa.Avalonia -c Release -r osx-arm64 --self-contained   # Mac (M-серия)
+dotnet publish src/Elfisa.Avalonia -c Release -r win-x64  --self-contained    # Windows
+```
+
+## Дорожная карта портирования
+Логика этих экранов частично уже есть в WinForms `ApiClient` — переносится
+в `Elfisa.Core` метод за методом, UI пишется по образцу `ReportsView`.
+
+| Раздел | Что нужно | Сложность |
+|---|---|---|
+| ✅ Прайс-лист | поиск + грид (/api/supplier-prices/summary) | готово (без добавления в заказ) |
+| ✅ Заказы | список + карточка заказа с позициями | готово |
+| ✅ Накладные | реестр приходных документов | готово |
+| ✅ Отчёты | 4 типа + ИИ → Word/Excel | готово |
+| ✅ Справочник | профиль + грузополучатели | готово |
+| ✅ Отправить | поиск → корзина → создание заказа (POST /api/buyer/orders) | готов UI; реальная отправка не тестировалась (создаёт заказ на проде) |
+| ⏳ Отказы | список отказных позиций | нужен серверный эндпоинт (RefuseItemsCount есть только в локальной БД WinForms) |
+| ⏳ Автообновление | аналог AutoUpdater под каждую ОС | не начато |
+
+**Прайс-лист/Заказы/Накладные** строятся на рабочих эндпоинтах
+(`supplier-prices/summary`, `buyer/report`). «Родные» `buyer/orders` и
+`buyer/catalog` возвращают 500 (баг квотинга PascalCase в GORM-билдере).
+Фикс для **buyer/orders** готов и застейджен (`es_api_service.exe.new`,
+apply-new-exe.bat) — после деплоя Заказы/Накладные перейдут на него.
+Каталог не используется (берём рабочий summary), его фикс — по желанию.
+
+Осталось: **Отправить** (корзина + создание заказа + DBF) и **Отказы**,
+плюс автообновление и сохранение сессии. Логика переносится из WinForms,
+переписывается только UI (XAML).
