 ## Overview
-Корпоративный конфигуратор серверов с offline-first архитектурой.
-Приложение работает через локальную SQLite базу, синхронизация с MariaDB выполняется фоново.
+Корпоративный конфигуратор серверов и формирование КП. MariaDB (RFQ_LOG) + SQLite для оффлайн.
 
-## Product Scope
-- Конфигуратор компонентов и расчёт КП
-- Проекты и конфигурации
-- Read-only просмотр прайслистов из локального кэша
-- Sync (pull компонентов/прайслистов, push локальных изменений)
+## Development Phases
 
-Из области исключены:
-- admin pricing UI/API
-- stock import
-- alerts
-- cron/importer утилиты
+### Phase 1: Pricelists in MariaDB ✅ DONE
+### Phase 2: Local SQLite Database ✅ DONE
 
-## Architecture
-- Local-first: чтение и запись происходят в SQLite
-- MariaDB используется как сервер синхронизации
-- Background worker: периодический sync push+pull
+### Phase 2.5: Full Offline Mode 🔶 IN PROGRESS
+**Local-first architecture:** приложение ВСЕГДА работает с SQLite, MariaDB только для синхронизации.
 
-## Guardrails
-- Не возвращать в проект удалённые legacy-разделы: cron jobs, importer utility, admin pricing, alerts, stock import.
-- Runtime-конфиг читается из user state (`config.yaml`) или через `-config` / `QFS_CONFIG_PATH`; не хранить рабочий `config.yaml` в репозитории.
-- `config.example.yaml` остаётся единственным шаблоном конфигурации в репо.
-- Любые изменения в sync должны сохранять local-first поведение: локальные CRUD не блокируются из-за недоступности MariaDB.
+**Принцип работы:**
+- ВСЕ операции (CRUD) выполняются в SQLite
+- При создании конфигурации:
+  1. Если online → проверить новые прайслисты на сервере → скачать если есть
+  2. Далее работаем с local_pricelists (и online, и offline одинаково)
+- Background sync: push pending_changes → pull updates
 
-## Key SQLite Data
-- `connection_settings`
-- `local_components`
-- `local_pricelists`, `local_pricelist_items`
-- `local_configurations`
-- `local_projects`
-- `pending_changes`
+**DONE:**
+- ✅ Sync queue table (pending_changes) - `internal/localdb/models.go`
+- ✅ Model converters: MariaDB ↔ SQLite - `internal/localdb/converters.go`
+- ✅ LocalConfigurationService: все CRUD через SQLite - `internal/services/local_configuration.go`
+- ✅ Pre-create pricelist check: `SyncPricelistsIfNeeded()` - `internal/services/sync/service.go`
+- ✅ Push pending changes: `PushPendingChanges()` - sync service + handlers
+- ✅ Sync API endpoints: `/api/sync/push`, `/pending/count`, `/pending`
+- ✅ Integrate LocalConfigurationService in main.go (replace ConfigurationService)
+- ✅ Add routes for new sync endpoints (`/api/sync/push`, `/pending/count`, `/pending`)
+- ✅ ConfigurationGetter interface for handler compatibility
+- ✅ Background sync worker: auto-sync every 5min (push + pull) - `internal/services/sync/worker.go`
+- ✅ UI: sync status indicator (pending badge + sync button + offline/online dot) - `web/templates/partials/sync_status.html`
+- ✅ RefreshPrices for local mode:
+  - `RefreshPrices()` / `RefreshPricesNoAuth()` в `local_configuration.go`
+  - Берёт цены из `local_components.current_price`
+  - Graceful degradation при отсутствии компонента
+  - Добавлено поле `price_updated_at` в `LocalConfiguration` (models.go:72)
+  - Обновлены converters для PriceUpdatedAt
+  - UI кнопка "Пересчитать цену" работает offline/online
+- ✅ Fixed sync bugs:
+  - Duplicate entry error при update конфигураций (`sync/service.go:334-365`)
+  - pushConfigurationUpdate теперь проверяет наличие server_id перед update
+  - Если нет ID → получает из LocalConfiguration.ServerID или ищет на сервере
+  - Fixed setup.go: `settings.Password` → `settings.PasswordEncrypted`
+
+**TODO:**
+- ❌ Conflict resolution (Phase 4, last-write-wins default)
+
+### UI Improvements ✅ MOSTLY DONE
+
+**1. Sync UI + pricelist badge: ✅ DONE**
+- ✅ `sync_status.html`: SVG иконки Online/Offline (кликабельные → открывают модал)
+- ✅ Кнопка sync → иконка circular arrows (только full sync)
+- ✅ Модальное окно "Статус системы" в `base.html` (info о БД, ошибки синхронизации)
+- ✅ `configs.html`: badge с версией активного прайслиста
+- ✅ Загрузка через `/api/pricelists/latest` при DOMContentLoaded
+- ✅ Удалён dropdown с Push changes (упрощение UI)
+
+**2. Прайслисты → вкладка в "Администратор цен": ✅ DONE**
+- ✅ `base.html`: убрана ссылка "Прайслисты" из навигации
+- ✅ `admin_pricing.html`: добавлена вкладка "Прайслисты"
+- ✅ Логика перенесена из `pricelists.html` (table, create modal, CRUD)
+- ✅ Route `/pricelists` → редирект на `/admin/pricing?tab=pricelists`
+- ✅ Поддержка URL param `?tab=pricelists`
+
+**3. Модал "Настройка цены" - кол-во котировок с учётом периода: ❌ TODO**
+- Текущее: показывает только общее кол-во котировок
+- Новое: показывать `N (всего: M)` где N - за выбранный период, M - всего
+- ❌ `admin_pricing.html`: обновить `#modal-quote-count`
+- ❌ `admin_pricing_handler.go`: в `/api/admin/pricing/preview` возвращать `quote_count_period` + `quote_count_total`
+
+**4. Страница настроек: ❌ ОТЛОЖЕНО**
+- Перенесено в Phase 3 (после основных UI улучшений)
+
+### Phase 3: Projects and Specifications
+- qt_projects, qt_specifications tables (MariaDB)
+- Replace qt_configurations → Project/Specification hierarchy
+- Fields: opty, customer_requirement, variant, qty, rev
+- Local projects/specs with server sync
+
+### Phase 4: Price Versioning
+- Bind specifications to pricelist versions
+- Price diff comparison
+- Auto-cleanup expired pricelists (>1 year, usage_count=0)
+
+## Tech Stack
+Go 1.22+ | Gin | GORM | MariaDB 11 | SQLite (glebarez/sqlite) | htmx + Tailwind CDN | excelize
+
+## Key Tables
+
+### READ-ONLY (external systems)
+- `lot` (lot_name PK, lot_description)
+- `lot_log` (lot, supplier, date, price, quality, comments)
+- `supplier` (supplier_name PK)
+
+### MariaDB (qt_* prefix)
+- `qt_lot_metadata` - component prices, methods, popularity
+- `qt_categories` - category codes and names
+- `qt_pricelists` - version snapshots (YYYY-MM-DD-NNN format)
+- `qt_pricelist_items` - prices per pricelist
+- `qt_projects` - uuid, opty, customer_requirement, name (Phase 3)
+- `qt_specifications` - project_id, pricelist_id, variant, rev, qty, items JSON (Phase 3)
+
+### SQLite (data/quoteforge.db)
+- `connection_settings` - encrypted DB credentials (PasswordEncrypted field)
+- `local_pricelists/items` - cached from server
+- `local_components` - lot cache for offline search (with current_price)
+- `local_configurations` - UUID, items, price_updated_at, sync_status (pending/synced/conflict), server_id
+- `local_projects/specifications` - Phase 3
+- `pending_changes` - sync queue (entity_type, uuid, op, payload, created_at, attempts, last_error)
+
+## Business Logic
+
+**Part number parsing:** `CPU_AMD_9654` → category=`CPU`, model=`AMD_9654`
+
+**Price methods:** manual | median | average | weighted_median
+
+**Price freshness:** fresh (<30d, ≥3 quotes) | normal (<60d) | stale (<90d) | critical
+
+**Pricelist version:** `YYYY-MM-DD-NNN` (e.g., `2024-01-31-001`)

+# Local-First Architecture Integration Guide
+
+## Overview
+
+QuoteForge теперь поддерживает local-first архитектуру: приложение ВСЕГДА работает с SQLite (localdb), MariaDB используется только для синхронизации.
+
+## Реализованные компоненты
+
+### 1. Конвертеры моделей (`internal/localdb/converters.go`)
+
+Конвертеры между MariaDB и SQLite моделями:
+- `ConfigurationToLocal()` / `LocalToConfiguration()`
+- `PricelistToLocal()` / `LocalToPricelist()`
+- `ComponentToLocal()` / `LocalToComponent()`
+
+### 2. LocalDB методы (`internal/localdb/localdb.go`)
+
+Добавлены методы для работы с pending changes:
+- `MarkChangesSynced(ids []int64)` - помечает изменения как синхронизированные
+- `GetPendingCount()` - возвращает количество несинхронизированных изменений
+
+### 3. Sync Service расширения (`internal/services/sync/service.go`)
+
+Новые методы:
+- `SyncPricelistsIfNeeded()` - проверяет и скачивает новые прайслисты при необходимости
+- `PushPendingChanges()` - отправляет все pending changes на сервер
+- `pushSingleChange()` - обрабатывает один pending change
+- `pushConfigurationCreate/Update/Delete()` - специфичные методы для конфигураций
+
+**ВАЖНО**: Конструктор изменен - теперь требует `ConfigurationRepository`:
+```go
+syncService := sync.NewService(pricelistRepo, configRepo, local)
+```
+
+### 4. LocalConfigurationService (`internal/services/local_configuration.go`)
+
+Новый сервис для работы с конфигурациями в local-first режиме:
+- Все операции CRUD работают через SQLite
+- Автоматически добавляет изменения в pending_changes
+- При создании конфигурации (если online) проверяет новые прайслисты
+
+```go
+localConfigService := services.NewLocalConfigurationService(
+    localDB,
+    syncService,
+    quoteService,
+    isOnlineFunc,
+)
+```
+
+### 5. Sync Handler расширения (`internal/handlers/sync.go`)
+
+Новые endpoints:
+- `POST /api/sync/push` - отправить pending changes на сервер
+- `GET /api/sync/pending/count` - получить количество pending changes
+- `GET /api/sync/pending` - получить список pending changes
+
+## Интеграция
+
+### Шаг 1: Обновить main.go
+
+```go
+// В cmd/qfs/main.go
+syncService := sync.NewService(pricelistRepo, configRepo, local)
+
+// Создать isOnline функцию
+isOnlineFunc := func() bool {
+    sqlDB, err := db.DB()
+    if err != nil {
+        return false
+    }
+    return sqlDB.Ping() == nil
+}
+
+// Создать LocalConfigurationService
+localConfigService := services.NewLocalConfigurationService(
+    local,
+    syncService,
+    quoteService,
+    isOnlineFunc,
+)
+```
+
+### Шаг 2: Обновить ConfigurationHandler
+
+Заменить `ConfigurationService` на `LocalConfigurationService` в handlers:
+
+```go
+// Было:
+configHandler := handlers.NewConfigurationHandler(configService, exportService)
+
+// Стало:
+configHandler := handlers.NewConfigurationHandler(localConfigService, exportService)
+```
+
+### Шаг 3: Добавить endpoints для sync
+
+В роутере добавить:
+```go
+syncGroup := router.Group("/api/sync")
+{
+    syncGroup.POST("/push", syncHandler.PushPendingChanges)
+    syncGroup.GET("/pending/count", syncHandler.GetPendingCount)
+    syncGroup.GET("/pending", syncHandler.GetPendingChanges)
+}
+```
+
+## Как это работает
+
+### Создание конфигурации
+
+1. Пользователь создает конфигурацию
+2. `LocalConfigurationService.Create()`:
+   - Если online → `SyncPricelistsIfNeeded()` проверяет новые прайслисты
+   - Сохраняет конфигурацию в SQLite
+   - Добавляет в `pending_changes` с operation="create"
+3. Конфигурация доступна локально сразу
+
+### Синхронизация с сервером
+
+**Manual sync:**
+```bash
+POST /api/sync/push
+```
+
+**Background sync (TODO):**
+- Периодический worker вызывает `syncService.PushPendingChanges()`
+- Проверяет online статус
+- Отправляет все pending changes на сервер
+- Удаляет успешно синхронизированные записи
+
+### Offline режим
+
+1. Все операции работают нормально через SQLite
+2. Изменения копятся в `pending_changes`
+3. При восстановлении соединения автоматически синхронизируются
+
+## Pending Changes Queue
+
+Таблица `pending_changes`:
+```go
+type PendingChange struct {
+    ID         int64     // Auto-increment
+    EntityType string    // "configuration", "project", "specification"
+    EntityUUID string    // UUID сущности
+    Operation  string    // "create", "update", "delete"
+    Payload    string    // JSON snapshot сущности
+    CreatedAt  time.Time
+    Attempts   int       // Счетчик попыток синхронизации
+    LastError  string    // Последняя ошибка синхронизации
+}
+```
+
+## TODO для Phase 2.5
+
+- [ ] Background sync worker (автоматическая синхронизация каждые N минут)
+- [ ] Conflict resolution (при конфликтах обновления)
+- [ ] UI: pending counter в header
+- [ ] UI: manual sync button
+- [ ] UI: conflict alerts
+- [ ] Retry logic для failed pending changes
+- [ ] RefreshPrices для local mode (через local_components)
+
+## Testing
+
+```bash
+# Compile
+go build ./cmd/qfs
+
+# Run
+./quoteforge
+
+# Check pending changes
+curl http://localhost:8080/api/sync/pending/count
+
+# Manual sync
+curl -X POST http://localhost:8080/api/sync/push
+```

+# Миграция: Функционал пересчета цен в конфигураторе
+
+## Описание изменений
+
+Добавлен функционал автоматического обновления цен компонентов в сохраненных конфигурациях.
+
+### Новые возможности
+
+1. **Кнопка "Пересчитать цену"** на странице конфигуратора
+   - Обновляет цены всех компонентов в конфигурации до актуальных значений из базы данных
+   - Сохраняет количество компонентов, обновляя только цены
+   - Отображает время последнего обновления цен
+
+2. **Поле `price_updated_at`** в таблице конфигураций
+   - Хранит дату и время последнего обновления цен
+   - Отображается на странице конфигуратора в удобном формате ("5 мин. назад", "2 ч. назад" и т.д.)
+
+### Изменения в базе данных
+
+Добавлено новое поле в таблицу `qt_configurations`:
+```sql
+ALTER TABLE qt_configurations
+ADD COLUMN price_updated_at TIMESTAMP NULL DEFAULT NULL
+AFTER server_count;
+```
+
+### Новый API endpoint
+
+```
+POST /api/configs/:uuid/refresh-prices
+```
+
+**Требования:**
+- Авторизация: Bearer Token
+- Роль: editor или выше
+
+**Ответ:**
+```json
+{
+  "id": 1,
+  "uuid": "...",
+  "name": "Конфигурация 1",
+  "items": [
+    {
+      "lot_name": "CPU_AMD_9654",
+      "quantity": 2,
+      "unit_price": 11500.00
+    }
+  ],
+  "total_price": 23000.00,
+  "price_updated_at": "2026-01-31T12:34:56Z",
+  ...
+}
+```
+
+## Применение изменений
+
+### 1. Обновление базы данных
+
+Запустите сервер с флагом миграции:
+```bash
+./quoteforge -migrate -config config.yaml
+```
+
+Или выполните SQL миграцию вручную:
+```bash
+mysql -u user -p RFQ_LOG < migrations/004_add_price_updated_at.sql
+```
+
+### 2. Перезапуск сервера
+
+После применения миграции перезапустите сервер:
+```bash
+./quoteforge -config config.yaml
+```
+
+## Использование
+
+1. Откройте любую сохраненную конфигурацию в конфигураторе
+2. Нажмите кнопку **"Пересчитать цену"** рядом с кнопкой "Сохранить"
+3. Все цены компонентов будут обновлены до актуальных значений
+4. Конфигурация автоматически сохраняется с обновленными ценами
+5. Под кнопками отображается время последнего обновления цен
+
+## Технические детали
+
+### Измененные файлы
+
+- `internal/models/configuration.go` - добавлено поле `PriceUpdatedAt`
+- `internal/services/configuration.go` - добавлен метод `RefreshPrices()`
+- `internal/handlers/configuration.go` - добавлен обработчик `RefreshPrices()`
+- `cmd/qfs/main.go` - добавлен маршрут `/api/configs/:uuid/refresh-prices`
+- `web/templates/index.html` - добавлена кнопка и JavaScript функции
+- `migrations/004_add_price_updated_at.sql` - SQL миграция
+- `CLAUDE.md` - обновлена документация
+
+### Логика обновления цен
+
+1. Получение конфигурации по UUID
+2. Проверка прав доступа (пользователь должен быть владельцем)
+3. Для каждого компонента в конфигурации:
+   - Получение актуальной цены из `qt_lot_metadata.current_price`
+   - Обновление `unit_price` в items
+4. Пересчет `total_price` с учетом `server_count`
+5. Установка `price_updated_at` на текущее время
+6. Сохранение конфигурации
+
+### Обработка ошибок
+
+- Если компонент не найден или у него нет цены - сохраняется старая цена
+- При ошибках доступа возвращается 403 Forbidden
+- При отсутствии конфигурации возвращается 404 Not Found
+
+## Отмена изменений (Rollback)
+
+Для отмены миграции выполните:
+```sql
+ALTER TABLE qt_configurations DROP COLUMN price_updated_at;
+```
+
+**Внимание:** После отмены миграции функционал пересчета цен перестанет работать корректно.

+## Cron Jobs
+
+QuoteForge now includes automated cron jobs for maintenance tasks. These can be run using the built-in cron functionality in the Docker container.
+
+### Docker Compose Setup
+
+The Docker setup includes a dedicated cron service that runs the following jobs:
+
+- **Alerts check**: Every hour (0 * * * *)
+- **Price updates**: Daily at 2 AM (0 2 * * *)
+- **Usage counter reset**: Weekly on Sunday at 1 AM (0 1 * * 0)
+- **Popularity score updates**: Daily at 3 AM (0 3 * * *)
+
+To enable cron jobs in Docker, run:
+
+```bash
+docker-compose up -d
+```
+
+### Manual Cron Job Execution
+
+You can also run cron jobs manually using the quoteforge-cron binary:
+
+```bash
+# Check and generate alerts
+go run ./cmd/cron -job=alerts
+
+# Recalculate all prices
+go run ./cmd/cron -job=update-prices
+
+# Reset usage counters
+go run ./cmd/cron -job=reset-counters
+
+# Update popularity scores
+go run ./cmd/cron -job=update-popularity
+```
+
+### Cron Job Details
+
+- **Alerts check**: Generates alerts for components with high demand and stale prices, trending components without prices, and components with no recent quotes
+- **Price updates**: Recalculates prices for all components using configured methods (median, weighted median, average)
+- **Usage counter reset**: Resets weekly and monthly usage counters for components
+- **Popularity score updates**: Recalculates popularity scores based on supplier quote activity
+
 ## Разработка

-# QuoteForge — План очистки (удаление admin pricing)
-
-Цель: убрать всё, что связано с администрированием цен, складскими справками, алертами.
-Оставить: конфигуратор, проекты, read-only просмотр прайслистов, sync, offline-first.
-
----
-
-## 1. Удалить файлы
-
-- [x] `internal/handlers/pricing.go` (40.6KB) — весь admin pricing UI
-- [x] `internal/services/pricing/` — весь пакет расчёта цен
-- [x] `internal/services/pricelist/` — весь пакет управления прайслистами
-- [x] `internal/services/stock_import.go` — импорт складских справок
-- [x] `internal/services/alerts/` — весь пакет алертов
-- [x] `internal/warehouse/` — алгоритмы расчёта цен по складу
-- [x] `web/templates/admin_pricing.html` (109KB) — страница admin pricing
-- [x] `cmd/cron/` — cron jobs (cleanup-pricelists, update-prices, update-popularity)
-- [x] `cmd/importer/` — утилита импорта данных
-
-## 2. Упростить `internal/handlers/pricelist.go` (read-only)
-
-Read-only методы (List, Get, GetItems, GetLotNames, GetLatest) уже работают
-только через `h.localDB` (SQLite) без `pricelist.Service`.
-
-- [x] Убрать поле `service *pricelist.Service` из структуры `PricelistHandler`
-- [x] Изменить конструктор: `NewPricelistHandler(localDB *localdb.LocalDB)`
-- [x] Удалить write-методы: `Create()`, `CreateWithProgress()`, `Delete()`, `SetActive()`, `CanWrite()`
-- [x] Удалить метод `refreshLocalPricelistCacheFromServer()` (зависит от service)
-- [x] Удалить import `pricelist` пакета
-- [x] Оставить: `List()`, `Get()`, `GetItems()`, `GetLotNames()`, `GetLatest()`
-
-## 3. Упростить `cmd/qfs/main.go`
-
-- [x] Удалить создание сервисов: `pricingService`, `alertService`, `pricelistService`, `stockImportService`
-- [x] Удалить хэндлер: `pricingHandler`
-- [x] Изменить создание `pricelistHandler`: `NewPricelistHandler(local)` (без service)
-- [x] Удалить repositories: `priceRepo`, `alertRepo` (statsRepo оставить — nil-safe)
-- [x] Удалить все routes `/api/admin/pricing/*` (строки ~1407-1430)
-- [x] Из `/api/pricelists/*` оставить только read-only:
-  - `GET ""` (List), `GET "/latest"`, `GET "/:id"`, `GET "/:id/items"`, `GET "/:id/lots"`
-- [x] Удалить write routes: `POST ""`, `POST "/create-with-progress"`, `PATCH "/:id/active"`, `DELETE "/:id"`, `GET "/can-write"`
-- [x] Удалить web page `/admin/pricing`
-- [x] Исправить `/pricelists` — вместо redirect на admin/pricing сделать страницу
-- [x] В `QuoteService` конструкторе: передавать `nil` для `pricingService`
-- [x] Удалить imports: `pricing`, `pricelist`, `alerts` пакеты
-
-## 4. Упростить `handlers/web.go`
-
-- [x] Удалить из `simplePages`: `admin_pricing.html`
-- [x] Удалить метод: `AdminPricing()`
-- [x] Оставить все остальные методы включая `Pricelists()` и `PricelistDetail()`
-
-## 5. Упростить `base.html` (навигация)
-
-- [x] Убрать ссылку "Администратор цен"
-- [x] Добавить ссылку "Прайслисты" (на `/pricelists`)
-- [x] Оставить: "Мои проекты", "Прайслисты", sync indicator
-
-## 6. Sync — оставить полностью
-
-- Background worker: pull компоненты + прайслисты, push конфигурации
-- Все `/api/sync/*` endpoints остаются
-- Это ядро offline-first архитектуры
-
-## 7. Верификация
-
-- [x] `go build ./cmd/qfs` — компилируется
-- [x] `go vet ./...` — без ошибок
-- [ ] Запуск → `/configs` работает
-- [ ] `/pricelists` — read-only список работает
-- [ ] `/pricelists/:id` — детали работают
-- [ ] Sync с сервером работает
-- [ ] Нет ссылок на admin pricing в UI
-
-## 8. Обновить CLAUDE.md
-- [x] Убрать разделы про admin pricing, stock import, alerts, cron
-- [x] Обновить API endpoints список
-- [x] Обновить описание приложения
