 # QuoteForge - Claude Code Instructions
 
 ## 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.

-#### Важные замечания
-
-- **Таблицы синхронизации** должны быть созданы администратором БД один раз. Приложение не требует прав CREATE TABLE.
-- **Прайслисты** (`qt_pricelists`, `qt_pricelist_items`) — справочные таблицы, управляются сервером, пользователь имеет только SELECT.
-- **Конфигурации и проекты** — таблицы, в которые пишет само приложение (INSERT, UPDATE при сохранении изменений).
-- **Таблицы миграций** нужны для синхронизации: приложение читает список миграций и отчитывается о применённых.
-- Если видите ошибку `Access denied for user ...@'<ip>'`, проверьте наличие конфликтующих записей пользователя с разными хостами (user@localhost vs 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.

+## 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
+

-# 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).

-# Промпт для ИИ: Перенос паттерна Прайслист
-
-Используй этот документ как промпт для ИИ при переносе реализации прайслиста в другой проект.
-
----
-
-## Задача
-
-Я имею рабочую реализацию окна "Прайслист" в проекте QuoteForge. Нужно перенести эту реализацию в проект [ДОП_ПРОЕКТ_НАЗВАНИЕ], сохраняя структуру, логику и UI/UX.
-
-## Что перенести
-
-### Frontend - Лист прайслистов (`/pricelists`)
-
-**Файл источник:** QuoteForge/web/templates/pricelists.html
-
-**Компоненты:**
-1. **Таблица** - список прайслистов с колонками:
-   - Версия (монофонт)
-   - Тип (estimate/warehouse/competitor)
-   - Дата создания
-   - Автор (обычно "sync")
-   - Позиций (количество товаров)
-   - Исп. (использований)
-   - Статус (зеленый "Активен" / серый "Неактивен")
-   - Действия (Просмотр, Удалить если не используется)
-
-2. **Пагинация** - навигация по страницам с активной страницей выделена
-
-3. **Модальное окно** - "Создать прайслист" (если есть прав на запись)
-
-**Что копировать:**
-- HTML структуру таблицы из lines 10-30
-- JavaScript функции:
-  - `loadPricelists(page)` - загрузка списка
-  - `renderPricelists(items)` - рендер таблицы
-  - `renderPagination(total, page, perPage)` - пагинация
-  - `checkPricelistWritePermission()` - проверка прав
-  - Модальные функции: `openCreateModal()`, `closeCreateModal()`, `createPricelist()`
-- CSS классы Tailwind (скопируются как есть)
-
-**Где использовать в дочернем проекте:**
-- URL: `/pricelists` (или адаптировать под ваши маршруты)
-- API: `GET /api/pricelists?page=1&per_page=20`
-
----
-
-### Frontend - Детали прайслиста (`/pricelists/:id`)
-
-**Файл источник:** QuoteForge/web/templates/pricelist_detail.html
-
-**Компоненты:**
-1. **Хлебная крошка** - кнопка назад на список
-
-2. **Инфо-панель** - сводка по прайслисту:
-   - Версия (монофонт)
-   - Дата создания
-   - Автор
-   - Позиций (количество)
-   - Использований (в скольких конфигах)
-   - Статус (зеленый/серый)
-   - Истекает (дата или "-")
-
-3. **Таблица товаров** - с поиском и пагинацией:
-   - Артикул (монофонт, lot_name)
-   - Категория (извлекается первая часть до "_")
-   - Описание (обрезается до 60 символов с "...")
-   - [УСЛОВНО] Доступно (qty) - только для warehouse источника
-   - [УСЛОВНО] Partnumbers - только для warehouse источника
-   - Цена, $ (с 2 знаками после запятой)
-   - Настройки (аббревиатуры: РУЧН, Сред, Взвеш.мед, периоды (1н, 1м, 3м, 1г), коэффициент, МЕТА)
-
-4. **Поиск** - дебаунс 300мс, поиск по lot_name
-
-5. **Динамические колонки** - qty и partnumbers скрываются/показываются в зависимости от source (warehouse или нет)
-
-**Что копировать:**
-- HTML структуру из lines 4-78
-- JavaScript функции:
-  - `loadPricelistInfo()` - загрузка деталей прайслиста
-  - `loadItems(page)` - загрузка товаров
-  - `renderItems(items)` - рендер таблицы товаров
-  - `renderItemsPagination(total, page, perPage)` - пагинация товаров
-  - `isWarehouseSource()` - проверка источника
-  - `toggleWarehouseColumns()` - показать/скрыть conditional колонки
-  - `formatQty(qty)` - форматирование количества
-  - `formatPriceSettings(item)` - форматирование строки настроек
-  - `escapeHtml(text)` - экранирование HTML
-  - Debounce для поиска (lines 300-306)
-- CSS классы Tailwind
-- Логику conditional колонок (lines 152-164)
-
-**Где использовать в дочернем проекте:**
-- URL: `/pricelists/:id`
-- API:
-  - `GET /api/pricelists/:id`
-  - `GET /api/pricelists/:id/items?page=1&per_page=50&search=...`
-
----
-
-### Backend - Handler
-
-**Файл источник:** QuoteForge/internal/handlers/pricelist.go
-
-**Методы для реализации:**
-
-1. **List** (lines 23-89)
-   - Параметры: `page`, `per_page`, `source` (фильтр), `active_only`
-   - Логика:
-     - Получить все прайслисты
-     - Отфильтровать по source (case-insensitive)
-     - Отсортировать по CreatedAt DESC (свежее сверху)
-     - Пагинировать
-     - Для каждого: посчитать товары (CountLocalPricelistItems), использования (IsUsed)
-     - Вернуть JSON с полями: id, source, version, created_by, item_count, usage_count, is_active, created_at, synced_from
-
-2. **Get** (lines 92-116)
-   - Параметр: `id` (uint из URL)
-   - Логика:
-     - Получить прайслист по ID
-     - Вернуть его детали (id, source, version, item_count, is_active, created_at)
-     - 404 если не найден
-
-3. **GetItems** (lines 119-181)
-   - Параметры: `id` (URL), `page`, `per_page`, `search` (query)
-   - Логика:
-     - Получить прайслист по ID
-     - Получить товары этого прайслиста
-     - Фильтровать по lot_name LIKE search (если передан)
-     - Посчитать total
-     - Пагинировать
-     - Для каждого товара: извлечь категорию из lot_name (первая часть до "_")
-     - Вернуть JSON: source, items (id, lot_name, price, category, available_qty, partnumbers), total, page, per_page
-
-4. **GetLotNames** (lines 183-211)
-   - Параметр: `id` (URL)
-   - Логика:
-     - Получить все lot_names из этого прайслиста
-     - Отсортировать alphabetically
-     - Вернуть JSON: lot_names (array of strings), total
-
-5. **GetLatest** (lines 214-233)
-   - Параметр: `source` (query, default "estimate")
-   - Логика:
-     - Нормализовать source (case-insensitive)
-     - Получить самый свежий прайслист по этому source
-     - Вернуть его детали
-     - 404 если не найден
-
-**Регистрация маршрутов:**
-```go
-pricelists := api.Group("/pricelists")
-{
-    pricelists.GET("", handler.List)
-    pricelists.GET("/latest", handler.GetLatest)
-    pricelists.GET("/:id", handler.Get)
-    pricelists.GET("/:id/items", handler.GetItems)
-    pricelists.GET("/:id/lots", handler.GetLotNames)
-}
-```
-
----
-
-## Адаптация для другого проекта
-
-### Что нужно изменить
-
-1. **Источник данных**
-   - QuoteForge использует local DB (LocalPricelist, LocalPricelistItem)
-   - В вашем проекте: замените на ваши структуры/таблицы
-   - Сущность "прайслист" может называться по-другому
-
-2. **API маршруты**
-   - `/api/pricelists` → ваш путь
-   - `:id` - может быть UUID вместо int, адаптировать parsing
-
-3. **Имена полей**
-   - Если у вас нет поля `version` - используйте ID или дату
-   - Если нет `source` - опустить фильтр
-   - Если нет `IsUsed` - считать как всегда 0
-
-4. **Структуры данных**
-   - Pricelist должна иметь: id, name/version, created_at, source, item_count
-   - PricelistItem должна иметь: id, lot_name, price, available_qty, partnumbers
-
-5. **Условные колонки**
-   - Логика: если source == "warehouse", показать qty и partnumbers
-   - Адаптировать под ваши источники/типы
-
-### Что копировать как есть
-
-- **HTML структура** - таблицы, модали, классы Tailwind
-- **JavaScript логика** - все функции загрузки, рендера, пагинации
-- **CSS классы** - Tailwind работает везде одинаково
-- **Форматирование функций** - formatPrice, formatQty, formatDate
-
----
-
-## Пошаговая инструкция для ИИ
-
-1. **Прочитай оба файла:**
-   - QuoteForge/web/templates/pricelists.html (список)
-   - QuoteForge/web/templates/pricelist_detail.html (детали)
-   - QuoteForge/internal/handlers/pricelist.go (backend)
-
-2. **Определи структуры данных в дочернем проекте:**
-   - Какая таблица хранит "прайслисты"?
-   - Какие у неё поля?
-   - Как связаны товары?
-
-3. **Адаптируй Backend:**
-   - Скопируй методы Handler
-   - Замени DB вызовы на вызовы вашего хранилища
-   - Замени имена полей в JSON ответах если нужно
-   - Убедись, что API возвращает нужный формат
-
-4. **Адаптируй Frontend - Список:**
-   - Скопируй HTML таблицу
-   - Скопируй функции load/render/pagination
-   - Замени маршруты `/pricelists` → ваши
-   - Замени API endpoint → ваш
-   - Протестируй список загружается
-
-5. **Адаптируй Frontend - Детали:**
-   - Скопируй HTML для деталей
-   - Скопируй функции loadInfo/loadItems/render
-   - Замени маршруты и endpoints
-   - Особое внимание на conditional колонки (toggleWarehouseColumns)
-   - Протестируй поиск работает
-
-6. **Протестируй:**
-   - Список загружается
-   - Пагинация работает
-   - Детали открываются
-   - Поиск работает
-   - Conditional колонки показываются/скрываются правильно
-   - Форматирование цен и дат работает
-
----
-
-## Пример адаптации
-
-### Backend (было):
-```go
-func (h *PricelistHandler) List(c *gin.Context) {
-    localPLs, err := h.localDB.GetLocalPricelists()
-    // ...
-}
-```
-
-### Backend (стало):
-```go
-func (h *CatalogHandler) List(c *gin.Context) {
-    catalogs, err := h.service.GetAllCatalogs(page, perPage)
-    // ...
-}
-```
-
-### Frontend (было):
-```javascript
-const resp = await fetch(`/api/pricelists?page=${page}&per_page=20`);
-```
-
-### Frontend (стало):
-```javascript
-const resp = await fetch(`/api/catalogs?page=${page}&per_page=20`);
-```
-
----
-
-## Качество результата
-
-Когда закончишь:
-- ✅ Список и детали выглядят идентично QuoteForge
-- ✅ Все функции работают (load, render, pagination, search, conditional columns)
-- ✅ Обработка ошибок (404, empty list, network errors)
-- ✅ Таблицы с Tailwind классами оформлены одинаково
-- ✅ Форматирование чисел/дат совпадает
-
----
-
-## Вопросы для ИИ
-
-Перед тем как давать этот промпт, ответь на эти вопросы:
-
-1. **Какие у тебя структуры данных для "прайслиста"?**
-   - Пример: какие поля, как называется таблица
-
-2. **Какие API endpoints уже есть?**
-   - Или нужно создать с нуля?
-
-3. **Есть ли уже разница в источниках (estimate/warehouse)?**
-   - Или все одного типа?
-
-4. **Нужна ли возможность создавать прайслисты?**
-   - Или только просмотр?
-
----
-
-## Чеклист для проверки
-
-После переноса проверь:
-
-- [ ] Backend: List возвращает правильный JSON
-- [ ] Backend: Get возвращает детали
-- [ ] Backend: GetItems возвращает товары с поиском
-- [ ] Frontend: Список загружается на `/pricelists`
-- [ ] Frontend: Клик на прайслист открывает `/pricelists/:id`
-- [ ] Frontend: Таблица на детальной странице рендеритсяся
-- [ ] Frontend: Поиск работает с дебаунсом
-- [ ] Frontend: Пагинация работает
-- [ ] Frontend: Conditional колонки показываются/скрываются
-- [ ] Frontend: Форматирование цен работает (2 знака)
-- [ ] Frontend: Форматирование дат работает (ru-RU)
-- [ ] UI: Выглядит идентично QuoteForge

-# v1.2.1 Release Notes
-
-**Date:** 2026-02-09
-**Changes since v1.2.0:** 2 commits
-
-## Summary
-Fixed configurator component substitution by updating to work with new pricelist-based pricing model. Addresses regression from v1.2.0 refactor that removed `CurrentPrice` field from components.
-
-## Commits
-
-### 1. Refactor: Remove CurrentPrice from local_components (5984a57)
-**Type:** Refactor
-**Files Changed:** 11 files, +167 insertions, -194 deletions
-
-#### Overview
-Transitioned from component-based pricing to pricelist-based pricing model:
-- Removed `CurrentPrice` and `SyncedAt` from LocalComponent (metadata-only now)
-- Added `WarehousePricelistID` and `CompetitorPricelistID` to LocalConfiguration
-- Removed 2 unused methods: UpdateComponentPricesFromPricelist, EnsureComponentPricesFromPricelists
-
-#### Key Changes
-- **Data Model:**
-  - LocalComponent: now stores only metadata (LotName, LotDescription, Category, Model)
-  - LocalConfiguration: added warehouse and competitor pricelist references
-
-- **Migrations:**
-  - drop_component_unused_fields - removes CurrentPrice, SyncedAt columns
-  - add_warehouse_competitor_pricelists - adds new pricelist fields
-
-- **Quote Calculation:**
-  - Updated to use pricelist_items instead of component.CurrentPrice
-  - Added PricelistID field to QuoteRequest
-  - Maintains offline-first behavior
-
-- **API:**
-  - Removed CurrentPrice from ComponentView
-  - Components API no longer returns pricing
-
-### 2. Fix: Load component prices via API (acf7c8a)
-**Type:** Bug Fix
-**Files Changed:** 1 file (web/templates/index.html), +66 insertions, -12 deletions
-
-#### Problem
-After v1.2.0 refactor, the configurator's autocomplete was filtering out all components because it checked for the removed `current_price` field on component objects.
-
-#### Solution
-Implemented on-demand price loading via API:
-- Added `ensurePricesLoaded()` function to fetch prices from `/api/quote/price-levels`
-- Added `componentPricesCache` to cache loaded prices in memory
-- Updated all 3 autocomplete modes (single, multi, section) to load prices when input is focused
-- Changed price validation from `c.current_price` to `hasComponentPrice(lot_name)`
-- Updated cart item creation to use cached API prices
-
-#### Impact
-- Components without prices are still filtered out (as required)
-- Price checks now use API data instead of removed database field
-- Frontend loads prices on-demand for better performance
-
-## Testing Notes
-- ✅ Configurator component substitution now works
-- ✅ Prices load correctly from pricelist
-- ✅ Offline mode still supported (prices cached after initial load)
-- ✅ Multi-pricelist support functional (estimate/warehouse/competitor)
-
-## Known Issues
-None
-
-## Migration Path
-No database migration needed from v1.2.0 - migrations were applied in v1.2.0 release.
-
-## Breaking Changes
-None for end users. Internal: `ComponentView` no longer includes `CurrentPrice` in API responses.

-# Release v1.2.2 (2026-02-09)
-
-## Summary
-
-Fixed CSV export filename inconsistency where project names weren't being resolved correctly. Standardized export format across both manual exports and project configuration exports to use `YYYY-MM-DD (project_name) config_name BOM.csv`.
-
-## Commits

-- `8f596ce` fix: standardize CSV export filename format to use project name
-
-## Changes
-
-### CSV Export Filename Standardization
-
-**Problem:**
-- ExportCSV and ExportConfigCSV had inconsistent filename formats
-- Project names sometimes fell back to config names when not explicitly provided
-- Export timestamps didn't reflect actual price update time
-
-**Solution:**
-- Unified format: `YYYY-MM-DD (project_name) config_name BOM.csv`
-- Both export paths now use PriceUpdatedAt if available, otherwise CreatedAt
-- Project name resolved from ProjectUUID via ProjectService for both paths
-- Frontend passes project_uuid context when exporting
-
-**Technical Details:**
-
-Backend:
-- Added `ProjectUUID` field to `ExportRequest` struct in handlers/export.go
-- Updated ExportCSV to look up project name from ProjectUUID using ProjectService
-- Ensured ExportConfigCSV gets project name from config's ProjectUUID
-- Both use CreatedAt (for ExportCSV) or PriceUpdatedAt/CreatedAt (for ExportConfigCSV)
-
-Frontend:
-- Added `projectUUID` and `projectName` state variables in index.html
-- Load and store projectUUID when configuration is loaded
-- Pass `project_uuid` in JSON body for both export requests
-
-## Files Modified
-
-- `internal/handlers/export.go` - Project name resolution and ExportRequest update
-- `internal/handlers/export_test.go` - Updated mock initialization with projectService param
-- `cmd/qfs/main.go` - Pass projectService to ExportHandler constructor
-- `web/templates/index.html` - Add projectUUID tracking and export payload updates
-
-## Testing Notes
-
-✅ All existing tests updated and passing
-✅ Code builds without errors
-✅ Export filename now includes correct project name
-✅ Works for both form-based and project-based exports
-
-## Breaking Changes
-
-None - API response format unchanged, only filename generation updated.
-
-## Known Issues
-
-None identified.

-# Release v1.2.3 (2026-02-10)
-
-## Summary
-
-Unified synchronization functionality with event-driven UI updates. Resolved user confusion about duplicate sync buttons by implementing a single sync source with automatic page refreshes.
-
-## Changes
-
-### Main Feature: Sync Event System
-
-- **Added `sync-completed` event** in base.html's `syncAction()` function
-  - Dispatched after successful `/api/sync/all` or `/api/sync/push`
-  - Includes endpoint and response data in event detail
-  - Enables pages to react automatically to sync completion
-
-### Configs Page (`configs.html`)
-
-- **Removed "Импорт с сервера" button** - duplicate functionality no longer needed
-- **Updated layout** - changed from 2-column grid to single button layout
-- **Removed `importConfigsFromServer()` function** - functionality now handled by navbar sync
-- **Added sync-completed event listener**:
-  - Automatically reloads configurations list after sync
-  - Resets pagination to first page
-  - New configurations appear immediately without manual refresh
-
-### Projects Page (`projects.html`)
-
-- **Wrapped initialization in DOMContentLoaded**:
-  - Moved `loadProjects()` and all event listeners inside handler
-  - Ensures DOM is fully loaded before accessing elements
-- **Added sync-completed event listener**:
-  - Automatically reloads projects list after sync
-  - New projects appear immediately without manual refresh
-
-### Pricelists Page (`pricelists.html`)
-
-- **Added sync-completed event listener** to existing DOMContentLoaded:
-  - Automatically reloads pricelists when sync completes
-  - Maintains existing permissions and modal functionality
-
-## Benefits
-
-### User Experience
-- ✅ Single "Синхронизация" button in navbar - no confusion about sync sources
-- ✅ Automatic list updates after sync - no need for manual F5 refresh
-- ✅ Consistent behavior across all pages (configs, projects, pricelists)
-- ✅ Better feedback: toast notification + automatic UI refresh
-
-### Architecture
-- ✅ Event-driven loose coupling between navbar and pages
-- ✅ Easy to extend to other pages (just add event listener)
-- ✅ No backend changes needed
-- ✅ Production-ready
-
-## Breaking Changes
-
-- **`/api/configs/import` endpoint** still works but UI button removed
-  - Users should use navbar "Синхронизация" button instead
-  - Backend API remains unchanged for backward compatibility
-
-## Files Modified
-
-1. `web/templates/base.html` - Added sync-completed event dispatch
-2. `web/templates/configs.html` - Event listener + removed duplicate UI
-3. `web/templates/projects.html` - DOMContentLoaded wrapper + event listener
-4. `web/templates/pricelists.html` - Event listener for auto-refresh
-
-**Stats:** 4 files changed, 59 insertions(+), 65 deletions(-)
-
-## Commits
-
-- `99fd80b` - feat: unify sync functionality with event-driven UI updates
-
-## Testing Checklist
-
-- [x] Configs page: New configurations appear after navbar sync
-- [x] Projects page: New projects appear after navbar sync
-- [x] Pricelists page: Pricelists refresh after navbar sync
-- [x] Both `/api/sync/all` and `/api/sync/push` trigger updates
-- [x] Toast notifications still show correctly
-- [x] Sync status indicator updates
-- [x] Error handling (423, network errors) still works
-- [x] Mode switching (Active/Archive) works correctly
-- [x] Backward compatibility maintained
-
-## Known Issues
-
-None - implementation is production-ready
-
-## Migration Notes
-
-No migration needed. Changes are frontend-only and backward compatible:
-- Old `/api/configs/import` endpoint still functional
-- No database schema changes
-- No configuration changes needed

-# QuoteForge v1.2.1
-
-**Дата релиза:** 2026-02-09
-**Тег:** `v1.2.1`
-**GitHub:** https://git.mchus.pro/mchus/QuoteForge/releases/tag/v1.2.1
-
-## Резюме
-
-Быстрый патч-релиз, исправляющий регрессию в конфигураторе после рефактора v1.2.0. После удаления поля `CurrentPrice` из компонентов, autocomplete перестал показывать компоненты. Теперь используется на-demand загрузка цен через API.
-
-## Что исправлено
-
-### 🐛 Configurator Component Substitution (acf7c8a)
-- **Проблема:** После рефактора в v1.2.0, autocomplete фильтровал ВСЕ компоненты, потому что проверял удаленное поле `current_price`
-- **Решение:** Загрузка цен на-demand через `/api/quote/price-levels`
-  - Добавлен `componentPricesCache` для кэширования цен в памяти
-  - Функция `ensurePricesLoaded()` загружает цены при фокусе на поле поиска
-  - Все 3 режима autocomplete (single, multi, section) обновлены
-  - Компоненты без цен по-прежнему фильтруются (как требуется), но проверка использует API
-- **Затронутые файлы:** `web/templates/index.html` (+66 строк, -12 строк)
-
-## История v1.2.0 → v1.2.1
-
-Всего коммитов: **2**
-
-| Хеш | Автор | Сообщение |
-|-----|-------|-----------|
-| `acf7c8a` | Claude | fix: load component prices via API instead of removed current_price field |
-| `5984a57` | Claude | refactor: remove CurrentPrice from local_components and transition to pricelist-based pricing |
-
-## Тестирование
-
-✅ Configurator component substitution работает
-✅ Цены загружаются корректно из pricelist
-✅ Offline режим поддерживается (цены кэшируются после первой загрузки)
-✅ Multi-pricelist поддержка функциональна (estimate/warehouse/competitor)
-
-## Breaking Changes
-
-Нет критических изменений для конечных пользователей.
-
-⚠️ **Для разработчиков:** `ComponentView` API больше не возвращает `CurrentPrice`.
-
-## Миграция
-
-Не требуется миграция БД — все миграции были применены в v1.2.0.

-# 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
