 # 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.
 
-## Key SQLite Data
-- `connection_settings`
-- `local_components`
-- `local_pricelists`, `local_pricelist_items`
-- `local_configurations`
-- `local_projects`
-- `pending_changes`
+**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`)

-# QuoteForge v1.0.3
-
-Дата релиза: 2026-02-06
-Тег: `v1.0.3`
-Диапазон изменений: `v1.0.2..v1.0.3`
-
-## Что нового
-
-- Добавлена страница управления проектами `/projects` с:
-  - датой и временем создания проекта;
-  - сортировкой по названию и дате создания;
-  - серверной пагинацией;
-  - фильтром по автору в заголовке таблицы.
-- Добавлена отдельная вкладка `Статус синхронизации` на уровне `Алерты / Компоненты / Прайслисты`.
-- Во вкладке статуса синхронизации отображаются:
-  - пользователь;
-  - версия приложения;
-  - статус (`онлайн` или относительное время последней синхронизации).
-
-## Изменения синхронизации
-
-- Реализован heartbeat синхронизации пользователей в MariaDB: `qt_pricelist_sync_status`.
-- Добавлен API `GET /api/sync/users-status` для UI статуса синхронизации.
-- Логика онлайн-статуса рассчитана от интервала фоновой синхронизации: `5 минут + 10%`.
-- В heartbeat фиксируется версия приложения (`app_version`).
-
-## Важные исправления
-
-- Исправлено восстановление отсутствующей серверной конфигурации при push обновлений.
-- Исправлено экранирование паролей в MySQL DSN в setup.
-- Улучшена логика запуска SQL-миграций на старте при отсутствии прав/необходимости.
-- Обновлена логика пересчета прайслистов через админский price-refresh.
-
-## Миграции и совместимость
-
-Добавлены SQL-миграции:
-
-- `migrations/010_add_pricelist_sync_status.sql`
-- `migrations/011_add_app_version_to_pricelist_sync_status.sql`
-
-Релиз совместим с предыдущей веткой `v1.0.x`; новая таблица синхронизации создается автоматически.
-
-## Коммиты в релизе
-
-- `b1b50ce` Add projects table controls and sync status tab with app version
-- `6ab1e98` sync: recover missing server config during update push
-- `a1d2192` Fix MySQL DSN escaping for setup passwords and clarify DB user setup
-- `a90c07c` update stale files list
-- `e9307c4` Apply remaining pricelist and local-first updates
-- `1b48401` Use admin price-refresh logic for pricelist recalculation
-- `4a86f7b` fix: skip startup sql migrations when not needed or no permissions
