 # QuoteForge - Claude Code Instructions
 
-## Bible
+## Overview
+Корпоративный конфигуратор серверов и формирование КП. MariaDB (RFQ_LOG) + SQLite для оффлайн.
 
-The **[bible/](bible/README.md)** is the single source of truth for this project's architecture, schemas, patterns, and rules. Read it before making any changes.
+## Development Phases
 
-**Rules:**
+### Phase 1: Pricelists in MariaDB ✅ DONE
-- Every architectural decision must be recorded in `bible/` in the same commit as the code.
+### Phase 2: Local SQLite Database ✅ DONE
-- Bible files are written and updated in **English only**.
-- Before working on the codebase, check `releases/memory/` for the latest release notes.
 
-## Quick Reference
+### Phase 2.5: Full Offline Mode 🔶 IN PROGRESS
+**Local-first architecture:** приложение ВСЕГДА работает с SQLite, MariaDB только для синхронизации.
 
+**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
+
+**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.

 ```
 
-Приложение: http://localhost:8080 → откроется `/setup` для настройки подключения к MariaDB.
+### Мигратор OPS -> проекты (preview/apply)
+
+Переносит квоты, чьи названия начинаются с `OPS-xxxx` (где `x` — цифра), в проект `OPS-xxxx`.
+Если проекта нет, он будет создан; если архивный — реактивирован.
+
+Сначала всегда смотрите preview:
 
 ```bash
-# Сборка
+go run ./cmd/migrate_ops_projects -config config.yaml
-make build-release
-
-# Проверка
-go build ./cmd/qfs && go vet ./...
 ```

+### Минимальные права БД для пользователя квотаций
+
+Если нужен пользователь, который может работать с конфигурациями, но не может создавать/удалять прайслисты:
+
+```sql
+-- 1) Создать (или оставить существующего) пользователя
+CREATE USER IF NOT EXISTS 'quote_user'@'%' IDENTIFIED BY 'StrongPassword!';
+
+-- 2) Сбросить лишние права (без пересоздания пользователя)
+REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'quote_user'@'%';
+
+-- 3) Чтение данных для конфигуратора и синка
+GRANT SELECT ON RFQ_LOG.lot TO 'quote_user'@'%';
+GRANT SELECT ON RFQ_LOG.qt_lot_metadata TO 'quote_user'@'%';
+GRANT SELECT ON RFQ_LOG.qt_categories TO 'quote_user'@'%';
+GRANT SELECT ON RFQ_LOG.qt_pricelists TO 'quote_user'@'%';
+GRANT SELECT ON RFQ_LOG.qt_pricelist_items TO 'quote_user'@'%';
+
+-- 4) Работа с конфигурациями
+GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_configurations TO 'quote_user'@'%';
+
+FLUSH PRIVILEGES;
+
+SHOW GRANTS FOR 'quote_user'@'%';
+```
+
+Важно:
+- не выдавайте `INSERT/UPDATE/DELETE` на `qt_pricelists` и `qt_pricelist_items`, если пользователь не должен управлять прайслистами;
+- если используется host-специфичный аккаунт (`'quote_user'@'192.168.x.x'`), назначьте права и для него;
+- после смены DB-настроек через `/setup` приложение перезапускается автоматически и подхватывает нового пользователя.

+make test            # Запуск тестов
+make clean           # Очистка bin/
+make help            # Показать все команды
+```
+
+Приложение будет доступно по адресу: http://localhost:8080
+
+### Локальная SQLite база (state)
+
+Локальная база приложения хранится в профиле пользователя и не зависит от расположения бинарника.
+Имя файла: `qfs.db`.
+
+- macOS: `~/Library/Application Support/QuoteForge/qfs.db`
+- Linux: `$XDG_STATE_HOME/quoteforge/qfs.db` (или `~/.local/state/quoteforge/qfs.db`)
+- Windows: `%LOCALAPPDATA%\\QuoteForge\\qfs.db`
+
+Можно переопределить путь через `-localdb` или переменную окружения `QFS_DB_PATH`.
+
+### Версионность конфигураций (local-first)
+
+Для `local_configurations` используется append-only versioning через полные snapshot-версии:
+
+- таблица: `local_configuration_versions`
+- для каждого изменения создаётся новая версия (`version_no = max + 1`)
+- `local_configurations.current_version_id` указывает на активную версию
+- старые версии не изменяются и не удаляются в обычном потоке
+- rollback не "перематывает" историю, а создаёт новую версию из выбранного snapshot
+
+При backfill (миграция `006_add_local_configuration_versions.sql`) для существующих конфигураций создаётся `v1` и проставляется `current_version_id`.
+
+#### Rollback
+
+Rollback выполняется API-методом:
+
+```bash
+POST /api/configs/:uuid/rollback
+{
+  "target_version": 3,
+  "note": "optional"
+}
+```
+
+Результат:
+- создаётся новая версия `vN` с `data` из целевой версии
+- `change_note = "rollback to v{target_version}"` (+ note, если передан)
+- `current_version_id` переключается на новую версию
+- конфигурация уходит в `sync_status = pending`
+
+### Локальный config.yaml
+
+По умолчанию `qfs` ищет `config.yaml` в той же user-state папке, где лежит `qfs.db` (а не рядом с бинарником).
+Можно переопределить путь через `-config` или `QFS_CONFIG_PATH`.

+## Роли пользователей
+
+| Роль | Описание |
+|------|----------|
+| `viewer` | Просмотр, создание квот, экспорт |
+| `editor` | + сохранение конфигураций |
+| `pricing_admin` | + управление ценами и алертами |
+| `admin` | Полный доступ, управление пользователями |
+
+## API
+
+Документация API доступна по адресу `/api/docs` (в разработке).
+
+Основные endpoints:
+
+```
+POST /api/auth/login          # Авторизация
+GET  /api/components          # Список компонентов
+POST /api/quote/calculate     # Расчёт цены
+POST /api/export/xlsx         # Экспорт в Excel
+GET  /api/configs             # Сохранённые конфигурации
+GET  /api/configs/:uuid/versions            # Список версий конфигурации
+GET  /api/configs/:uuid/versions/:version   # Получить конкретную версию
+POST /api/configs/:uuid/rollback            # Rollback на указанную версию
+POST /api/configs/:uuid/reactivate          # Вернуть архивную конфигурацию в активные
+```
+
+#### Sync payload для versioning
+
+События в `pending_changes` для конфигураций содержат:
+- `configuration_uuid`
+- `operation` (`create` / `update` / `rollback`)
+- `current_version_id` и `current_version_no`
+- `snapshot` (текущее состояние конфигурации)
+- `idempotency_key` и `conflict_policy` (`last_write_wins`)
+
+Это позволяет push-слою отправлять на сервер актуальное состояние и готовит основу для будущего conflict resolution.
+
+## 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
+
+```bash
+# Запуск в режиме разработки (hot reload)
+go run ./cmd/qfs
+
+# Запуск тестов
+go test ./...
+
+# Сборка для Linux
+CGO_ENABLED=0 go build -ldflags="-s -w" -o bin/qfs ./cmd/qfs
+```
+
+## Переменные окружения
+
+| Переменная | Описание | По умолчанию |
+|------------|----------|--------------|
+| `QF_DB_HOST` | Хост базы данных | localhost |
+| `QF_DB_PORT` | Порт базы данных | 3306 |
+| `QF_DB_NAME` | Имя базы данных | RFQ_LOG |
+| `QF_DB_USER` | Пользователь БД | — |
+| `QF_DB_PASSWORD` | Пароль БД | — |
+| `QF_JWT_SECRET` | Секрет для JWT | — |
+| `QF_SERVER_PORT` | Порт сервера | 8080 |
+| `QFS_DB_PATH` | Полный путь к локальной SQLite БД | OS-specific user state dir |
+| `QFS_STATE_DIR` | Каталог state (если `QFS_DB_PATH` не задан) | OS-specific user state dir |
+| `QFS_CONFIG_PATH` | Полный путь к `config.yaml` | OS-specific user state dir |
+
+## Интеграция с существующей БД
+
+QuoteForge интегрируется с существующей базой RFQ_LOG:
+
+- `lot` — справочник компонентов (только чтение)
+- `lot_log` — история цен от поставщиков (только чтение)
+- `supplier` — справочник поставщиков (только чтение)
+
+Новые таблицы QuoteForge имеют префикс `qt_`:

-# 02 — Architecture

-## Local-First Principle
-
-**SQLite** is the single source of truth for the user.
-**MariaDB** is a sync server only — it never blocks local operations.
-
-```
-User
-  │
-  ▼
-SQLite (qfs.db)          ← all CRUD operations go here
-  │
-  │ background sync (every 5 min)
-  ▼
-MariaDB (RFQ_LOG)        ← pull/push only
-```
-
-**Rules:**
-- All CRUD operations go through SQLite only
-- If MariaDB is unavailable → local work continues without restrictions
-- Changes are queued in `pending_changes` and pushed on next sync
-
----

-### Sync Direction by Entity
-
-| Entity | Direction |
-|--------|-----------|
-| Configurations | Client ↔ Server ↔ Other Clients |
-| Projects | Client ↔ Server ↔ Other Clients |
-| Pricelists | Server → Clients only (no push) |
-| Components | Server → Clients only |
-
-Local pricelists not present on the server and not referenced by active configurations are deleted automatically on sync.
-
-### Soft Deletes (Archive Pattern)
-
-Configurations and projects are **never hard-deleted**. Deletion is archive via `is_active = false`.
-
-- `DELETE /api/configs/:uuid` → sets `is_active = false` (archived); can be restored via `reactivate`
-- `DELETE /api/projects/:uuid` → archives a project **variant** only (`variant` field must be non-empty); main projects cannot be deleted via this endpoint
-
-## Sync Readiness Guard
-
-Before every push/pull, a preflight check runs:
-1. Is the server (MariaDB) reachable?
-2. Can centralized local DB migrations be applied?
-3. Does the application version satisfy `min_app_version` of pending migrations?
-
-**If the check fails:**
-- Local CRUD continues without restriction
-- Sync API returns `423 Locked` with `reason_code` and `reason_text`
-- UI shows a red indicator with the block reason
-
----
-
-## Pricing
-
-### Principle
-
-**Prices come only from `local_pricelist_items`.**
-Components (`local_components`) are metadata-only — they contain no pricing information.
-
-### Lookup Pattern
-
-```go
-// Look up a price for a line item
-price, found := s.lookupPriceByPricelistID(pricelistID, lotName)
-if found && price > 0 {
-    // use price
-}
-
-// Inside lookupPriceByPricelistID:
-localPL, err := s.localDB.GetLocalPricelistByServerID(pricelistID)
-price, err := s.localDB.GetLocalPriceForLot(localPL.ID, lotName)
-```
-
-### Multi-Level Pricelists
-
-A configuration can reference up to three pricelists simultaneously:
-
-| Field | Purpose |
-|-------|---------|
-| `pricelist_id` | Primary (estimate) |
-| `warehouse_pricelist_id` | Warehouse pricing |
-| `competitor_pricelist_id` | Competitor pricing |
-
-Pricelist sources: `estimate` | `warehouse` | `competitor`
-
-### "Auto" Pricelist Selection
-
-Configurator supports explicit and automatic selection per source (`estimate`, `warehouse`, `competitor`):
-
-- **Explicit mode:** concrete `pricelist_id` is set by user in settings.
-- **Auto mode:** client sends no explicit ID for that source; backend resolves the current latest active pricelist.
-
-`auto` must stay `auto` after price-level refresh and after manual "refresh prices":
-- resolved IDs are runtime-only and must not overwrite user's mode;
-- switching to explicit selection must clear runtime auto resolution for that source.
-
-### Latest Pricelist Resolution Rules
-
-For both server (`qt_pricelists`) and local cache (`local_pricelists`), "latest by source" is resolved with:
-
-1. only pricelists that have at least one item (`EXISTS ...pricelist_items`);
-2. deterministic sort: `created_at DESC, id DESC`.
-
-This prevents selecting empty/incomplete snapshots and removes nondeterministic ties.
-
----
-
-## Configuration Versioning
-
-### Principle
-
-Append-only: every save creates an immutable snapshot in `local_configuration_versions`.
-
-```
-local_configurations
-  └── current_version_id ──► local_configuration_versions (v3)  ← active
-                              local_configuration_versions (v2)
-                              local_configuration_versions (v1)
-```
-
-- `version_no = max + 1` on every save
-- Old versions are never modified or deleted in normal flow
-- Rollback does **not** rewind history — it creates a **new** version from the snapshot
-
-### Rollback
-
-```bash
-POST /api/configs/:uuid/rollback
-{
-  "target_version": 3,
-  "note": "optional comment"
-}
-```
-
-Result:
-- A new version `vN` is created with `data` from the target version
-- `change_note = "rollback to v{target_version}"` (+ note if provided)
-- `current_version_id` is switched to the new version
-- Configuration moves to `sync_status = pending`
-
-### Sync Status Flow
-
-```
-local → pending → synced
-```
-
----
-
-## Sync Payload for Versioning
-
-Events in `pending_changes` for configurations contain:
-
-| Field | Description |
-|-------|-------------|
-| `configuration_uuid` | Identifier |
-| `operation` | `create` / `update` / `rollback` |
-| `current_version_id` | Active version ID |
-| `current_version_no` | Version number |
-| `snapshot` | Current configuration state |
-| `idempotency_key` | For idempotent push |
-| `conflict_policy` | `last_write_wins` |
-
----
-
-## Background Processes
-
-| Process | Interval | What it does |
-|---------|----------|--------------|
-| Sync worker | 5 min | push pending + pull all |
-| Backup scheduler | configurable (`backup.time`) | creates ZIP archives |

-### SQLite Migrations (local)
-
-- Stored in `migrations/` (SQL files)
-- Applied via `-migrate` flag or automatically on first run
-- Idempotent: checked by `id` in `local_schema_migrations`
-- Already-applied migrations are skipped

-
-### Centralized Migrations (server-side)
-
-- Stored in `qt_client_local_migrations` (MariaDB)
-- Applied automatically during sync readiness check
-- `min_app_version` — minimum app version required for the migration

-# 06 — Backup
-
-## Overview
-
-Automatic rotating ZIP backup system for local data.
-
-**What is included in each archive:**
-- SQLite DB (`qfs.db`)
-- SQLite sidecars (`qfs.db-wal`, `qfs.db-shm`) if present
-- `config.yaml` if present
-
-**Archive name format:** `qfs-backp-YYYY-MM-DD.zip`
-
-**Retention policy:**
-| Period | Keep |
-|--------|------|
-| Daily | 7 archives |
-| Weekly | 4 archives |
-| Monthly | 12 archives |
-| Yearly | 10 archives |
-
-**Directories:** `<backup root>/daily`, `/weekly`, `/monthly`, `/yearly`
-
----
-
-## Configuration
-
-```yaml
-backup:
-  time: "00:00"   # Trigger time in local time (HH:MM format)
-```
-
-**Environment variables:**
-- `QFS_BACKUP_DIR` — backup root directory (default: `<db dir>/backups`)
-- `QFS_BACKUP_DISABLE` — disable backups (`1/true/yes`)
-
----
-
-## Behavior
-
-- **At startup:** if no backup exists for the current period, one is created immediately
-- **Daily:** at the configured time, a new backup is created
-- **Deduplication:** prevented via a `.period.json` marker file in each period directory
-- **Rotation:** excess old archives are deleted automatically
-
----
-
-## Implementation
-
-Module: `internal/appstate/backup.go`
-
-Main function:
-```go
-func EnsureRotatingLocalBackup(dbPath, configPath string) ([]string, error)
-```
-
-Scheduler (in `main.go`):
-```go
-func startBackupScheduler(ctx context.Context, cfg *config.Config, dbPath, configPath string)
-```
-
-### Config struct
-
-```go
-type BackupConfig struct {
-    Time string `yaml:"time"`
-}
-// Default: "00:00"
-```
-
----
-
-## Implementation Notes
-
-- `backup.time` is in **local time** without timezone offset parsing
-- `.period.json` is the marker that prevents duplicate backups within the same period
-- Archive filenames contain only the date; uniqueness is ensured by per-period directories + the period marker
-- When changing naming or retention: update both the filename logic and the prune logic together

-
-### What Must Never Be Restored
-
-The following components were **intentionally removed** and must not be brought back:
-- cron jobs
-- importer utility
-- admin pricing UI/API
-- alerts
-- stock import
-
-### Configuration Files
-
-- `config.yaml` — runtime user file, **not stored in the repository**
-- `config.example.yaml` — the only config template in the repo
-
-### Sync and Local-First
-
-- Any sync changes must preserve local-first behavior
-- Local CRUD must not be blocked when MariaDB is unavailable
-
-### Formats and UI
-
-- **CSV export:** filename must use **project code** (`project.Code`), not project name
-  Format: `YYYY-MM-DD (ProjectCode) ConfigName Article.csv`
-- **Breadcrumbs UI:** names longer than 16 characters must be truncated with an ellipsis
-
-### Architecture Documentation
-
-- **Every architectural decision must be recorded in `bible/`**
-- The corresponding Bible file must be updated **in the same commit** as the code change
-- On every user-requested commit, review and update the Bible in that same commit
-

-
-## Common Tasks
-
-### Add a Field to Configuration
-
-1. Add the field to `LocalConfiguration` struct (`internal/models/`)
-2. Add GORM tags for the DB column
-3. Write a SQL migration (`migrations/`)
-4. Update `ConfigurationToLocal` / `LocalToConfiguration` converters
-5. Update API handlers and services
-
-### Add a Field to Component
-
-1. Add the field to `LocalComponent` struct (`internal/models/`)
-2. Update the SQL query in `SyncComponents()`
-3. Update the `componentRow` struct to match
-4. Update converter functions
-
-### Add a Pricelist Price Lookup
-
-```go
-// Modern pattern
-price, found := s.lookupPriceByPricelistID(pricelistID, lotName)
-if found && price > 0 {
-    // use price
-}
-```
-
----
-
-## Known Gotchas
-
-1. **`CurrentPrice` removed from components** — any code using it will fail to compile
-2. **`HasPrice` filter removed** — `component.go ListComponents` no longer supports this filter
-3. **Quote calculation:** always offline-first (SQLite); online path is separate
-4. **Items JSON:** prices are stored in the `items` field of the configuration, not fetched from components
-5. **Migrations are additive:** already-applied migrations are skipped (checked by `id` in `local_schema_migrations`)
-6. **`SyncedAt` removed:** last component sync time is now in `app_settings` (key=`last_component_sync`)
-
----
-
-## Debugging Price Issues
-
-**Problem: quote returns no prices**
-1. Check that `pricelist_id` is set on the configuration
-2. Check that pricelist items exist: `SELECT COUNT(*) FROM local_pricelist_items`
-3. Check `lookupPriceByPricelistID()` in `quote.go`
-4. Verify the correct source is used (estimate/warehouse/competitor)
-
-**Problem: component sync not working**
-1. Components sync as metadata only — no prices
-2. Prices come via a separate pricelist sync
-3. Check `SyncComponents()` and the MariaDB query
-
-**Problem: configuration refresh does not update prices**
-1. Refresh uses the latest estimate pricelist by default
-2. Latest resolution ignores pricelists without items (`EXISTS local_pricelist_items`)
-3. Old prices in `config.items` are preserved if a line item is not found in the pricelist
-4. To force a pricelist update: set `configuration.pricelist_id`
-5. In configurator, `Авто` must remain auto-mode (runtime resolved ID must not be persisted as explicit selection)

-## Bible Rules
-
-> **Every architectural decision must be recorded in the Bible.**
->
-> Any change to DB schema, data access patterns, sync behavior, API contracts,
-> configuration format, or any other system-level aspect — the corresponding `bible/` file
-> **must be updated in the same commit** as the code.
->
-> On every user-requested commit, the Bible must be reviewed and updated in that commit.
->
-> The Bible is the single source of truth for architecture. Outdated documentation is worse than none.
-
-> **Documentation language: English.**
->
-> All files in `bible/` are written and updated **in English only**.
-> Mixing languages is not allowed.

-
-## Quick Reference
-
-**Where is user data stored?**
-SQLite → `~/Library/Application Support/QuoteForge/qfs.db` (macOS). MariaDB is sync-only.
-
-**How to look up a price for a line item?**
-`local_pricelist_items` → by `pricelist_id` from config + `lot_name`. Prices are **never** taken from `local_components`.
-
-**Pre-commit check?**
-`go build ./cmd/qfs && go vet ./...`
-
-**What must never be restored?**
-cron jobs, admin pricing, alerts, stock import, importer utility — all removed intentionally.
-
-**Where is the release changelog?**
-`releases/memory/v{major}.{minor}.{patch}.md`

-# Changes summary (2026-02-11)
-
-Implemented strict `lot_category` flow using `pricelist_items.lot_category` only (no parsing from `lot_name`), plus local caching and backfill:
-
-1. Local DB schema + migrations
-- Added `lot_category` column to `local_pricelist_items` via `LocalPricelistItem` model.
-- Added local migration `2026_02_11_local_pricelist_item_category` to add the column if missing and create indexes:
-  - `idx_local_pricelist_items_pricelist_lot (pricelist_id, lot_name)`
-  - `idx_local_pricelist_items_lot_category (lot_category)`
-
-2. Server model/repository
-- Added `LotCategory` field to `models.PricelistItem`.
-- `PricelistRepository.GetItems` now sets `Category` from `LotCategory` (no parsing from `lot_name`).
-
-3. Sync + local DB helpers
-- `SyncPricelistItems` now saves `lot_category` into local cache via `PricelistItemToLocal`.
-- Added `LocalDB.CountLocalPricelistItemsWithEmptyCategory` and `LocalDB.ReplaceLocalPricelistItems`.
-- Added `LocalDB.GetLocalLotCategoriesByServerPricelistID` for strict category lookup.
-- Added `SyncPricelists` backfill step: for used active pricelists with empty categories, force refresh items from server.
-
-4. API handler
-- `GET /api/pricelists/:id/items` returns `category` from `local_pricelist_items.lot_category` (no parsing from `lot_name`).
-
-5. Article category foundation
-- New package `internal/article`:
-  - `ResolveLotCategoriesStrict` pulls categories from local pricelist items and errors on missing category.
-  - `GroupForLotCategory` maps only allowed codes (CPU/MEM/GPU/M2/SSD/HDD/EDSFF/HHHL/NIC/HCA/DPU/PSU/PS) to article groups; excludes `SFP`.
-  - Error type `MissingCategoryForLotError` with base `ErrMissingCategoryForLot`.
-
-6. Tests
-- Added unit tests for converters and article category resolver.
-- Added handler test to ensure `/api/pricelists/:id/items` returns `lot_category`.
-- Added sync test for category backfill on used pricelist items.
-- `go test ./...` passed.
-
-Additional fixes (2026-02-11):
-- Fixed article parsing bug: CPU/GPU parsers were swapped in `internal/article/generator.go`. CPU now uses last token from CPU lot; GPU uses model+memory from `GPU_vendor_model_mem_iface`.
-- Adjusted configurator base tab layout to align labels on the same row (separate label row + input row grid).
-
-UI rule (2026-02-19):
-- In all breadcrumbs, truncate long specification/configuration names to 16 characters using ellipsis.
