feat: improve admin pricing modal quote count display to show period and total counts

- Added CountErroredChanges() method to count only pending changes with LastError
- Previously, error count included all pending changes, not just failed ones
- Added /api/sync/info endpoint with proper error count and error list
- Added sync info modal to display sync status, error count, and error details
- Made sync status indicators clickable to open the modal
- Fixed disconnect between "Error count: 4" and "No errors" in the list

+### Phase 1: Pricelists in MariaDB ✅ DONE
+### Phase 2: Local SQLite Database ✅ DONE
 
+### 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/server/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/server
+
+# 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/server/main.go` - добавлен маршрут `/api/configs/:uuid/refresh-prices`
+- `web/templates/index.html` - добавлена кнопка и JavaScript функции
+- `migrations/004_add_price_updated_at.sql` - SQL миграция
+- `CLAUDE.md` - обновлена документация
+
+### Логика обновления цен
+
+1. Получение конфигурации по UUID
+2. Проверка прав доступа (пользователь должен быть владельцем)
+3. Для каждого компонента в конфигурации:
+   - Получение актуальной цены из `qt_lot_metadata.current_price`
+   - Обновление `unit_price` в items
+4. Пересчет `total_price` с учетом `server_count`
+5. Установка `price_updated_at` на текущее время
+6. Сохранение конфигурации
+
+### Обработка ошибок
+
+- Если компонент не найден или у него нет цены - сохраняется старая цена
+- При ошибках доступа возвращается 403 Forbidden
+- При отсутствии конфигурации возвращается 404 Not Found
+
+## Отмена изменений (Rollback)
+
+Для отмены миграции выполните:
+```sql
+ALTER TABLE qt_configurations DROP COLUMN price_updated_at;
+```
+
+**Внимание:** После отмены миграции функционал пересчета цен перестанет работать корректно.

+## Cron Jobs
+
+QuoteForge now includes automated cron jobs for maintenance tasks. These can be run using the built-in cron functionality in the Docker container.
+
+### Docker Compose Setup
+
+The Docker setup includes a dedicated cron service that runs the following jobs:
+
+- **Alerts check**: Every hour (0 * * * *)
+- **Price updates**: Daily at 2 AM (0 2 * * *)
+- **Usage counter reset**: Weekly on Sunday at 1 AM (0 1 * * 0)
+- **Popularity score updates**: Daily at 3 AM (0 3 * * *)
+
+To enable cron jobs in Docker, run:
+
+```bash
+docker-compose up -d
+```
+
+### Manual Cron Job Execution
+
+You can also run cron jobs manually using the quoteforge-cron binary:
+
+```bash
+# Check and generate alerts
+go run ./cmd/cron -job=alerts
+
+# Recalculate all prices
+go run ./cmd/cron -job=update-prices
+
+# Reset usage counters
+go run ./cmd/cron -job=reset-counters
+
+# Update popularity scores
+go run ./cmd/cron -job=update-popularity
+```
+
+### Cron Job Details
+
+- **Alerts check**: Generates alerts for components with high demand and stale prices, trending components without prices, and components with no recent quotes
+- **Price updates**: Recalculates prices for all components using configured methods (median, weighted median, average)
+- **Usage counter reset**: Resets weekly and monthly usage counters for components
+- **Popularity score updates**: Recalculates popularity scores based on supplier quote activity
+
+## Разработка
+
+```bash
+# Запуск в режиме разработки (hot reload)
+go run ./cmd/server
+
+# Запуск тестов
 go test ./...
-go vet ./...
-make build-release
+
+# Сборка для Linux
+CGO_ENABLED=0 go build -ldflags="-s -w" -o bin/quoteforge ./cmd/server
 ```
 
-On first run the app creates a minimal `config.yaml`, starts on `http://127.0.0.1:8080`, and opens `/setup` if DB credentials were not saved yet.

-# 01 - Overview
-
-## Product
-
-QuoteForge is a local-first tool for server configuration, quotation, and project tracking.
-
-Core user flows:
-- create and edit configurations locally;
-- calculate prices from synced pricelists;
-- group configurations into projects and variants;
-- import vendor workspaces and map vendor PNs to internal LOTs;
-- review revision history and roll back safely.
-
-## Runtime model
-
-QuoteForge is a single-user thick client.
-
-Rules:
-- runtime HTTP binds to loopback only;
-- browser requests are treated as part of the same local user session;
-- MariaDB is not a live dependency for normal CRUD;
-- if non-loopback deployment is ever introduced, auth/RBAC must be added first.
-
-## Product scope
-
-In scope:
-- configurator and quote calculation;
-- projects, variants, and configuration ordering;
-- local revision history;
-- read-only pricelist browsing from SQLite cache;
-- background sync with MariaDB;
-- rotating local backups.
-
-Out of scope and intentionally removed:
-- admin pricing UI/API;
-- alerts and notification workflows;
-- stock import tooling;
-- cron jobs and importer utilities.

-# 02 - Architecture
-
-## Local-first rule
-
-SQLite is the runtime source of truth.
-MariaDB is sync transport plus setup and migration tooling.
-
-```text
-browser -> Gin handlers -> SQLite
-                        -> pending_changes
-background sync <------> MariaDB
-```
-
-Rules:
-- user CRUD must continue when MariaDB is offline;
-- runtime handlers and pages must read and write SQLite only;
-- MariaDB access in runtime code is allowed only inside sync and setup flows;
-- no live MariaDB fallback for reads that already exist in local cache.
-
-## Sync contract
-
-Bidirectional:
-- projects;
-- configurations;
-- `vendor_spec`;
-- pending change metadata.
-
-Pull-only:
-- components;
-- pricelists and pricelist items;
-- partnumber books and partnumber book items.
-
-Readiness guard:
-- every sync push/pull runs a preflight check;
-- blocked sync returns `423 Locked` with a machine-readable reason;
-- local work continues even when sync is blocked.
-- sync metadata updates must preserve project `updated_at`; sync time belongs in `synced_at`, not in the user-facing last-modified timestamp.
-- pricelist pull must persist a new local snapshot atomically: header and items appear together, and `last_pricelist_sync` advances only after item download succeeds.
-- UI sync status must distinguish "last sync failed" from "up to date"; if the app can prove newer server pricelist data exists, the indicator must say local cache is incomplete.
-
-## Pricing contract
-
-Prices come only from `local_pricelist_items`.
-
-Rules:
-- `local_components` is metadata-only;
-- quote calculation must not read prices from components;
-- latest pricelist selection ignores snapshots without items;
-- auto pricelist mode stays auto and must not be persisted as an explicit resolved ID.
-
-## Pricing tab layout
-
-The Pricing tab (Ценообразование) has two tables: Buy (Цена покупки) and Sale (Цена продажи).
-
-Column order (both tables):
-
-```
-PN вендора | Описание | LOT | Кол-во | Estimate | Склад | Конкуренты | Ручная цена
-```
-
-Per-LOT row expansion rules:
-- each `lot_mappings` entry in a BOM row becomes its own table row with its own quantity and prices;
-- `baseLot` (resolved LOT without an explicit mapping) is treated as the first sub-row with `quantity_per_pn` from `_getRowLotQtyPerPN`;
-- when one vendor PN expands into N LOT sub-rows, PN вендора and Описание cells use `rowspan="N"` and appear only on the first sub-row;
-- a visual top border (`border-t border-gray-200`) separates each vendor PN group.
-
-Vendor price attachment:
-- `vendorOrig` and `vendorOrigUnit` (BOM unit/total price) are attached to the first LOT sub-row only;
-- subsequent sub-rows carry empty `data-vendor-orig` so `setPricingCustomPriceFromVendor` counts each vendor PN exactly once.
-
-Controls terminology:
-- custom price input is labeled **Ручная цена** (not "Своя цена");
-- the button that fills custom price from BOM totals is labeled **BOM Цена** (not "Проставить цены BOM").
-
-CSV export reads PN вендора, Описание, and LOT from `data-vendor-pn`, `data-desc`, `data-lot` row attributes to bypass the rowspan cell offset problem.
-
-## Configuration versioning
-
-Configuration revisions are append-only snapshots stored in `local_configuration_versions`.
-
-Rules:
-- the editable working configuration is always the implicit head named `main`; UI must not switch the user to a numbered revision after save;
-- create a new revision when spec, BOM, or pricing content changes;
-- revision history is retrospective: the revisions page shows past snapshots, not the current `main` state;
-- rollback creates a new head revision from an old snapshot;
-- rename, reorder, project move, and similar operational edits do not create a new revision snapshot;
-- revision deduplication includes `items`, `server_count`, `total_price`, `custom_price`, `vendor_spec`, pricelist selectors, `disable_price_refresh`, and `only_in_stock`;
-- BOM updates must use version-aware save flow, not a direct SQL field update;
-- current revision pointer must be recoverable if legacy or damaged rows are found locally.
-
-## Sync UX
-
-UI-facing sync status must never block on live MariaDB calls.
-
-Rules:
-- navbar sync indicator and sync info modal read only local cached state from SQLite/app settings;
-- background/manual sync may talk to MariaDB, but polling endpoints must stay fast even on slow or broken connections;
-- any MariaDB timeout/invalid-connection during sync must invalidate the cached remote handle immediately so UI stops treating the connection as healthy.
-
-## Naming collisions
-
-UI-driven rename and copy flows use one suffix convention for conflicts.
-
-Rules:
-- configuration and variant names must auto-resolve collisions with `_копия`, then `_копия2`, `_копия3`, and so on;
-- copy checkboxes and copy modals must prefill `_копия`, not ` (копия)`;
-- the literal variant name `main` is reserved and must not be allowed for non-main variants.
-
-## Configuration types
-
-Configurations have a `config_type` field: `"server"` (default) or `"storage"`.
-
-Rules:
-- `config_type` defaults to `"server"` for all existing and new configurations unless explicitly set;
-- the configurator page is shared for both types; the SW tab is always visible regardless of type;
-- storage configurations use the same vendor_spec + PN→LOT + pricing flow as server configurations;
-- storage component categories map to existing tabs: `ENC`/`DKC`/`CTL` → Base, `HIC` → PCI (HIC-карты СХД; `HBA`/`NIC` — серверные, не смешивать), `SSD`/`HDD` → Storage (используют существующие серверные LOT), `ACC` → Accessories (используют существующие серверные LOT), `SW` → SW.
-- `DKC` = контроллерная полка (модель СХД + тип дисков + кол-во слотов + кол-во контроллеров); `CTL` = контроллер (кэш + встроенные порты); `ENC` = дисковая полка без контроллера.
-
-## Vendor BOM contract
-
-Vendor BOM is stored in `vendor_spec` on the configuration row.
-
-Rules:
-- PN to LOT resolution uses the active local partnumber book;
-- canonical persisted mapping is `lot_mappings[]`;
-- QuoteForge does not use legacy BOM tables such as `qt_bom`, `qt_lot_bundles`, or `qt_lot_bundle_items`.

-# 03 - Database
-
-## SQLite
-
-SQLite is the local runtime database.
-
-Main tables:
-
-| Table | Purpose |
-| --- | --- |
-| `local_components` | synced component metadata |
-| `local_pricelists` | local pricelist headers |
-| `local_pricelist_items` | local pricelist rows, the only runtime price source |
-| `local_projects` | user projects |
-| `local_configurations` | user configurations |
-| `local_configuration_versions` | immutable revision snapshots |
-| `local_partnumber_books` | partnumber book headers |
-| `local_partnumber_book_items` | PN -> LOT catalog payload |
-| `pending_changes` | sync queue |
-| `connection_settings` | encrypted MariaDB connection settings |
-| `app_settings` | local app state |
-| `local_schema_migrations` | applied local migration markers |
-
-Rules:
-- cache tables may be rebuilt if local migration recovery requires it;
-- user-authored tables must not be dropped as a recovery shortcut;
-- `local_pricelist_items` is the only valid runtime source of prices;
-- configuration `items` and `vendor_spec` are stored as JSON payloads inside configuration rows.
-
-## MariaDB
-
-MariaDB is the central sync database (`RFQ_LOG`). Final schema as of 2026-04-15.
-
-### QuoteForge tables (qt_*)
-
-Runtime read:
-- `qt_categories` — pricelist categories
-- `qt_lot_metadata` — component metadata, price settings
-- `qt_pricelists` — pricelist headers (source: estimate / warehouse / competitor)
-- `qt_pricelist_items` — pricelist rows
-- `qt_partnumber_books` — partnumber book headers
-- `qt_partnumber_book_items` — PN→LOT catalog payload
-
-Runtime read/write:
-- `qt_projects` — projects
-- `qt_configurations` — configurations
-- `qt_client_schema_state` — per-client sync status and version tracking
-- `qt_pricelist_sync_status` — pricelist sync timestamps per user
-
-Insert-only tracking:
-- `qt_vendor_partnumber_seen` — vendor partnumbers encountered during sync
-
-Server-side only (not queried by client runtime):
-- `qt_component_usage_stats` — aggregated component popularity stats (written by server jobs)
-- `qt_pricing_alerts` — price anomaly alerts (models exist in Go; feature disabled in runtime)
-- `qt_schema_migrations` — server migration history (applied via `go run ./cmd/qfs -migrate`)
-- `qt_scheduler_runs` — server background job tracking (no Go code references it in this repo)
-
-### Competitor subsystem (server-side only, not used by QuoteForge Go code)
-
-- `qt_competitors` — competitor registry
-- `partnumber_log_competitors` — competitor price log (FK → qt_competitors)
-
-These tables exist in the schema and are maintained by another tool or workflow.
-QuoteForge references competitor pricelists only via `qt_pricelists` (source='competitor').
-
-### Legacy RFQ tables (pre-QuoteForge, no Go code references)
-
-- `lot` — original component registry (data preserved; superseded by `qt_lot_metadata`)
-- `lot_log` — original supplier price log
-- `supplier` — supplier registry (FK target for lot_log and machine_log)
-- `machine` — device model registry
-- `machine_log` — device price/quote log
-- `parts_log` — supplier partnumber log used by server-side import/pricing workflows, not by QuoteForge runtime
-
-These tables are retained for historical data. QuoteForge does not read or write them at runtime.
-
-Rules:
-- QuoteForge runtime must not depend on any legacy RFQ tables;
-- QuoteForge sync reads prices and categories from `qt_pricelists` / `qt_pricelist_items` only;
-- QuoteForge does not enrich local pricelist rows from `parts_log` or any other raw supplier log table;
-- normal UI requests must not query MariaDB tables directly;
-- `qt_client_local_migrations` exists in the 2026-04-15 schema dump, but runtime sync does not depend on it.

-## Runtime files
-
-| Artifact | Default location |
-| --- | --- |
-| `qfs.db` | OS-specific user state directory |
-| `config.yaml` | same state directory as `qfs.db` |
-| `local_encryption.key` | same state directory as `qfs.db` |
-| `backups/` | next to `qfs.db` unless overridden |
-
-The runtime state directory can be overridden with `QFS_STATE_DIR`.
-Direct paths can be overridden with `QFS_DB_PATH` and `QFS_CONFIG_PATH`.
-
-## Runtime config shape
-
-Runtime keeps `config.yaml` intentionally small:
-
-```yaml
-server:
-  host: "127.0.0.1"
-  port: 8080
-  mode: "release"
-  read_timeout: 30s
-  write_timeout: 30s
-
-backup:
-  time: "00:00"
-
-logging:
-  level: "info"
-  format: "json"
-  output: "stdout"
-```
-
-Rules:
-- QuoteForge creates this file automatically if it does not exist;
-- startup rewrites legacy config files into this minimal runtime shape;
-- startup normalizes any `server.host` value to `127.0.0.1` before saving the runtime config;
-- `server.host` must stay on loopback.
-
-Saved MariaDB credentials do not live in `config.yaml`.
-They are stored in SQLite and encrypted with `local_encryption.key` unless `QUOTEFORGE_ENCRYPTION_KEY` overrides the key material.
-
-## Environment variables
-
-| Variable | Purpose |
-| --- | --- |
-| `QFS_STATE_DIR` | override runtime state directory |
-| `QFS_DB_PATH` | explicit SQLite path |
-| `QFS_CONFIG_PATH` | explicit config path |
-| `QFS_BACKUP_DIR` | explicit backup root |
-| `QFS_BACKUP_DISABLE` | disable rotating backups |
-| `QUOTEFORGE_ENCRYPTION_KEY` | override encryption key |
-| `QF_SERVER_PORT` | override HTTP port |
-
-`QFS_BACKUP_DISABLE` accepts `1`, `true`, or `yes`.
-
-## CLI flags
-
-| Flag | Purpose |
-| --- | --- |
-| `-config <path>` | config file path |
-| `-localdb <path>` | SQLite path |
-| `-reset-localdb` | destructive local DB reset |
-| `-migrate` | apply server migrations and exit |
-| `-version` | print app version and exit |
-
-## First run
-
-1. runtime ensures `config.yaml` exists;
-2. runtime opens the local SQLite database;
-3. if no stored MariaDB credentials exist, `/setup` is served;
-4. after setup, runtime works locally and sync uses saved DB settings in the background.

-# 06 - Backup
-
-## Scope
-
-QuoteForge creates rotating local ZIP backups of:
-- a consistent SQLite snapshot saved as `qfs.db`;
-- `config.yaml` when present.
-
-The backup intentionally does not include `local_encryption.key`.
-
-## Location and naming
-
-Default root:
-- `<db dir>/backups`
-
-Subdirectories:
-- `daily/`
-- `weekly/`
-- `monthly/`
-- `yearly/`
-
-Archive name:
-- `qfs-backp-YYYY-MM-DD.zip`
-
-## Retention
-
-| Period | Keep |
-| --- | --- |
-| Daily | 7 |
-| Weekly | 4 |
-| Monthly | 12 |
-| Yearly | 10 |
-
-## Behavior
-
-- on startup, QuoteForge creates a backup if the current period has none yet;
-- a daily scheduler creates the next backup at `backup.time`;
-- duplicate snapshots inside the same period are prevented by a period marker file;
-- old archives are pruned automatically.
-
-## Safety rules
-
-- backup root must be outside the git worktree;
-- backup creation is blocked if the resolved backup root sits inside the repository;
-- SQLite snapshot must be created from a consistent database copy, not by copying live WAL files directly;
-- restore to another machine requires re-entering DB credentials unless the encryption key is migrated separately.
-
-## Restore
-
-1. stop QuoteForge;
-2. unpack the chosen archive outside the repository;
-3. replace `qfs.db`;
-4. replace `config.yaml` if needed;
-5. restart the app;
-6. re-enter MariaDB credentials if the original encryption key is unavailable.

-# 09 - Vendor BOM
-
-## Storage contract
-
-Vendor BOM is stored in `local_configurations.vendor_spec` and synced with `qt_configurations.vendor_spec`.
-
-Each row uses this canonical shape:
-
-```json
-{
-  "sort_order": 10,
-  "vendor_partnumber": "ABC-123",
-  "quantity": 2,
-  "description": "row description",
-  "unit_price": 4500.0,
-  "total_price": 9000.0,
-  "lot_mappings": [
-    { "lot_name": "LOT_A", "quantity_per_pn": 1 }
-  ]
-}
-```
-
-Rules:
-- `lot_mappings[]` is the only persisted PN -> LOT mapping contract;
-- QuoteForge does not use legacy BOM tables;
-- apply flow rebuilds cart rows from `lot_mappings[]`.
-
-## Partnumber books
-
-Partnumber books are pull-only snapshots from PriceForge.
-
-Local tables:
-- `local_partnumber_books`
-- `local_partnumber_book_items`
-
-Server tables:
-- `qt_partnumber_books`
-- `qt_partnumber_book_items`
-
-Resolution flow:
-1. load the active local book;
-2. find `vendor_partnumber`;
-3. copy `lots_json` into `lot_mappings[]`;
-4. keep unresolved rows editable in the UI.
-
-## CFXML import
-
-`POST /api/projects/:uuid/vendor-import` imports one vendor workspace into an existing project.
-
-Rules:
-- accepted file field is `file`;
-- maximum file size is `1 GiB`;
-- one `ProprietaryGroupIdentifier` becomes one QuoteForge configuration;
-- software rows stay inside their hardware group and never become standalone configurations;
-- primary group row is selected structurally, without vendor-specific SKU hardcoding;
-- imported configuration order follows workspace order.
-
-Imported configuration fields:
-- `name` from primary row `ProductName`
-- `server_count` from primary row `Quantity`
-- `server_model` from primary row `ProductDescription`
-- `article` or `support_code` from `ProprietaryProductIdentifier`
-
-Imported BOM rows become `vendor_spec` rows and are resolved through the active local partnumber book when possible.
-
-## Inspur BOM import
-
-The same endpoint `POST /api/projects/:uuid/vendor-import` also accepts Inspur text BOM exports.
-
-Format: one component per line, `<partnumber>*<quantity>`. A leading `|` character is optional and stripped. Trailing whitespace around `*` is normalised.
-
-Example:
-```
-|CPU_AMD_9535-EPYC2.4_64C_256M_300W*1

-# Руководство по составлению каталога лотов СХД
-
-## Что такое LOT и зачем он нужен
-
-LOT — это внутренний идентификатор типа компонента в системе QuoteForge.
-
-Каждый LOT представляет одну рыночную позицию и хранит **средневзвешенную рыночную цену**, рассчитанную по историческим данным от поставщиков. Это позволяет получать актуальную оценку стоимости независимо от конкретного поставщика или прайс-листа.
-
-Партномера вендора (Part Number, Feature Code) сами по себе не имеют цены в системе — они **переводятся в LOT** через книгу партномеров. Именно через LOT происходит расценка конфигурации.
-
-**Пример:** Feature Code `B4B9` и Part Number `4C57A14368` — это два разных обозначения одной и той же HIC-карты от Lenovo. Оба маппируются на один LOT `HIC_4pFC32`, у которого есть рыночная цена.
-
----
-
-## Категории и вкладки конфигуратора
-
-Категория LOT определяет, в какой вкладке конфигуратора он появится.
-
-| Код категории | Название | Вкладка | Что сюда относится |
-|---|---|---|---|
-| `ENC` | Storage Enclosure | **Base** | Дисковая полка без контроллера |
-| `DKC` | Disk/Controller Enclosure | **Base** | Контроллерная полка: модель СХД + тип дисков + кол-во слотов + кол-во контроллеров |
-| `CTL` | Storage Controller | **Base** | Контроллер СХД: объём кэша + встроенные хост-порты |
-| `HIC` | Host Interface Card | **PCI** | HIC-карты СХД: интерфейсы подключения (FC, iSCSI, SAS) |
-| `HDD` | HDD | **Storage** | Жёсткие диски (HDD) |
-| `SSD` | SSD | **Storage** | Твердотельные диски (SSD, NVMe) |
-| `ACC` | Accessories | **Accessories** | Кабели подключения, кабели питания |
-| `SW` | Software | **SW** | Программные лицензии |
-| *(прочее)* | — | **Other** | Гарантийные опции, инсталляция |
-
----
-
-## Правила именования LOT
-
-Формат: `КАТЕГОРИЯ_МОДЕЛЬСХД_СПЕЦИФИКА`
-
-- только латиница, цифры и знак `_`
-- регистр — ВЕРХНИЙ
-- без пробелов, дефисов, точек
-- каждый LOT уникален — два разных компонента не могут иметь одинаковое имя
-
-### DKC — контроллерная полка
-
-Специфика: `ТИПДИСКА_СЛОТЫ_NCTRL`
-
-| Пример | Расшифровка |
-|---|---|
-| `DKC_DE4000H_SFF_24_2CTRL` | DE4000H, 24 слота SFF (2.5"), 2 контроллера |
-| `DKC_DE4000H_LFF_12_2CTRL` | DE4000H, 12 слотов LFF (3.5"), 2 контроллера |
-| `DKC_DE4000H_SFF_24_1CTRL` | DE4000H, 24 слота SFF, 1 контроллер (симплекс) |
-
-Обозначения типа диска: `SFF` — 2.5", `LFF` — 3.5", `NVMe` — U.2/U.3.
-
-### CTL — контроллер
-
-Специфика: `КЭШГБ_ПОРТЫТИП` (если встроенные порты есть) или `КЭШГБ_BASE` (если без портов, добавляются через HIC)
-
-| Пример | Расшифровка |
-|---|---|
-| `CTL_DE4000H_32GB_BASE` | 32GB кэш, без встроенных хост-портов |
-| `CTL_DE4000H_8GB_BASE` | 8GB кэш, без встроенных хост-портов |
-| `CTL_MSA2060_8GB_ISCSI10G_4P` | 8GB кэш, встроенные 4× iSCSI 10GbE |
-
-### HIC — HIC-карты (интерфейс подключения)
-
-Специфика: `NpПРОТОКОЛ` — без привязки к модели СХД, по аналогии с серверными `HBA_2pFC16`, `HBA_4pFC32_Gen6`.
-
-| Пример | Расшифровка |
-|---|---|
-| `HIC_4pFC32` | 4 порта FC 32Gb |
-| `HIC_4pFC16` | 4 порта FC 16G/10GbE |
-| `HIC_4p25G_iSCSI` | 4 порта 25G iSCSI |
-| `HIC_4p12G_SAS` | 4 порта SAS 12Gb |
-| `HIC_2p10G_BaseT` | 2 порта 10G Base-T |
-
-### HDD / SSD / NVMe — диски
-
-Диски **не привязываются к модели СХД** — используются существующие LOT из серверного каталога (`HDD_...`, `SSD_...`, `NVME_...`). Новые LOT для дисков СХД не создаются; партномера дисков маппируются на уже существующие серверные LOT.
-
-### ACC — кабели
-
-Кабели **не привязываются к модели СХД**. Формат: `ACC_CABLE_{ТИП}_{ДЛИНА}` — универсальные LOT, одинаковые для серверов и СХД.
-
-| Пример | Расшифровка |
-|---|---|
-| `ACC_CABLE_CAT6_10M` | Кабель CAT6 10м |
-| `ACC_CABLE_FC_OM4_3M` | Кабель FC LC-LC OM4 до 3м |
-| `ACC_CABLE_PWR_C13C14_15M` | Кабель питания C13–C14 1.5м |
-
-### SW — программные лицензии
-
-Специфика: краткое название функции.
-
-| Пример | Расшифровка |
-|---|---|
-| `SW_DE4000H_ASYNC_MIRROR` | Async Mirroring |
-| `SW_DE4000H_SNAPSHOT_512` | Snapshot 512 |
