 # QuoteForge - Claude Code Instructions
 
 ## Overview
-Корпоративный конфигуратор серверов и формирование КП. MariaDB (RFQ_LOG) + SQLite для оффлайн.
+Корпоративный конфигуратор серверов с offline-first архитектурой.
+Приложение работает через локальную SQLite базу, синхронизация с MariaDB выполняется фоново.
 
-## Development Phases
+## Product Scope
+- Конфигуратор компонентов и расчёт КП
+- Проекты и конфигурации
+- Read-only просмотр прайслистов из локального кэша
+- Sync (pull компонентов/прайслистов, push локальных изменений)
 
-### Phase 1: Pricelists in MariaDB ✅ DONE
+Из области исключены:
-### Phase 2: Local SQLite Database ✅ DONE
+- admin pricing UI/API
+- stock import
+- alerts
+- cron/importer утилиты
 
-### Phase 2.5: Full Offline Mode 🔶 IN PROGRESS
+## Architecture
-**Local-first architecture:** приложение ВСЕГДА работает с SQLite, MariaDB только для синхронизации.
+- Local-first: чтение и запись происходят в SQLite
+- MariaDB используется как сервер синхронизации
+- Background worker: периодический sync push+pull
 
-**Принцип работы:**
+## Key SQLite Data
-- ВСЕ операции (CRUD) выполняются в SQLite
+- `connection_settings`
-- При создании конфигурации:
+- `local_components`
-  1. Если online → проверить новые прайслисты на сервере → скачать если есть
+- `local_pricelists`, `local_pricelist_items`
-  2. Далее работаем с local_pricelists (и online, и offline одинаково)
+- `local_configurations`
-- Background sync: push pending_changes → pull updates
+- `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`)
