feat: unify sync functionality with event-driven UI updates

- Refactored navbar sync button to dispatch 'sync-completed' event
- Configs page: removed duplicate 'Импорт с сервера' button, added auto-refresh on sync
- Projects page: wrapped initialization in DOMContentLoaded, added auto-refresh on sync
- Pricelists page: added auto-refresh on sync completion
- Consistent UX: all lists update automatically after 'Синхронизация' button click
- Removed code duplication: importConfigsFromServer() function no longer needed
- Event-driven architecture enables easy extension to other pages

-## Shared Engineering Rules
-Read `bible/` — shared rules for all projects (CSV, logging, DB, tables, background tasks, code style).
-Start with `bible/rules/patterns/` for specific contracts.
+## Overview
+Корпоративный конфигуратор серверов с offline-first архитектурой.
+Приложение работает через локальную SQLite базу, синхронизация с MariaDB выполняется фоново.
 
-## Project Architecture
-Read `bible-local/` — QuoteForge specific architecture.
-Read order: `bible-local/README.md` → relevant files for the task.
+## Product Scope
+- Конфигуратор компонентов и расчёт КП
+- Проекты и конфигурации
+- Read-only просмотр прайслистов из локального кэша
+- Sync (pull компонентов/прайслистов, push локальных изменений)
 
-Every architectural decision specific to this project must be recorded in `bible-local/`.
+Из области исключены:
+- admin pricing UI/API
+- stock import
+- alerts
+- cron/importer утилиты
 
+## Architecture
+- Local-first: чтение и запись происходят в SQLite
+- MariaDB используется как сервер синхронизации
+- Background worker: периодический sync push+pull
+
+## 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.
+
+## Key SQLite Data
+- `connection_settings`
+- `local_components`
+- `local_pricelists`, `local_pricelist_items`
+- `local_configurations`
+- `local_projects`
+- `pending_changes`

 # QuoteForge
 
-Local-first desktop web app for server configuration, quotation, and project work.
+**Server Configuration & Quotation Tool**
 
-Runtime model:
-- user work is stored in local SQLite;
-- MariaDB is used only for setup checks and background sync;
-- HTTP server binds to loopback only.
+QuoteForge — корпоративный инструмент для конфигурирования серверов и формирования коммерческих предложений (КП).  
+Приложение работает в strict local-first режиме: пользовательские операции выполняются через локальную SQLite, MariaDB используется для синхронизации и серверного администрирования прайслистов.
 
-## What the app does
+![Go Version](https://img.shields.io/badge/Go-1.22+-00ADD8?style=flat&logo=go)
+![License](https://img.shields.io/badge/License-Proprietary-red)
+![Status](https://img.shields.io/badge/Status-In%20Development-yellow)
 
-- configuration editor with price refresh from synced pricelists;
-- projects with variants and ordered configurations;
-- vendor BOM import and PN -> LOT resolution;
-- revision history with rollback;
-- rotating local backups.
+## Возможности
 
-## Run
+### Для пользователей
+- 📱 **Mobile-first интерфейс** — удобная работа с телефона и планшета
+- 🖥️ **Конфигуратор серверов** — пошаговый выбор компонентов с проверкой совместимости
+- 💰 **Автоматический расчёт цен** — актуальные цены на основе истории закупок
+- 📊 **Экспорт в CSV/XLSX** — готовые спецификации для клиентов
+- 💾 **Сохранение конфигураций** — история и шаблоны для повторного использования
+- 🔌 **Полная офлайн-работа** — можно продолжать работу без сети и синхронизировать позже
+- 🛡️ **Защищенная синхронизация** — sync блокируется preflight-проверкой, если локальная схема не готова
+
+### Для ценовых администраторов
+- 📈 **Умный расчёт цен** — медиана, взвешенная медиана, среднее
+- 🎯 **Система алертов** — уведомления о популярных компонентах с устаревшими ценами
+- 📉 **Аналитика использования** — какие компоненты востребованы в КП
+- ⚙️ **Гибкие настройки** — периоды расчёта, методы, ручные переопределения
+
+### Индикация актуальности цен
+| Цвет | Статус | Условие |
+|------|--------|---------|
+| 🟢 Зелёный | Свежая | < 30 дней, ≥ 3 источника |
+| 🟡 Жёлтый | Нормальная | 30-60 дней |
+| 🟠 Оранжевый | Устаревающая | 60-90 дней |
+| 🔴 Красный | Устаревшая | > 90 дней или нет данных |
+
+## Технологии
+
+- **Backend:** Go 1.22+, Gin, GORM
+- **Frontend:** HTML, Tailwind CSS, htmx
+- **Database:** SQLite (runtime/local-first), MariaDB 11+ (sync + server admin)
+- **Export:** excelize (XLSX), encoding/csv
+
+## Требования
+
+- Go 1.22 или выше
+- MariaDB 11.x (или MySQL 8.x)
+- ~50 MB дискового пространства
+
+## Установка
+
+### 1. Клонирование репозитория
 
 ```bash
-go run ./cmd/qfs
+git clone https://github.com/your-company/quoteforge.git
+cd quoteforge
 ```
 
-Useful commands:
+### 2. Настройка runtime-конфига (опционально)
+
+`config.yaml` создаётся автоматически при первом старте в той же user-state папке, где находится `qfs.db`.
+Если найден старый формат, приложение автоматически мигрирует файл в актуальный runtime-формат
+(оставляя только используемые секции `server` и `logging`).
+
+При необходимости можно создать/отредактировать файл вручную:
+
+```yaml
+server:
+  host: "0.0.0.0"
+  port: 8080
+  mode: "release"
+
+logging:
+  level: "info"
+  format: "json"
+  output: "stdout"
+```
+
+### 3. Миграции базы данных
 
 ```bash
 go run ./cmd/qfs -migrate
-go test ./...
-go vet ./...
-make build-release
 ```
 
-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.
+### Мигратор OPS -> проекты (preview/apply)
 
-## Documentation
+Переносит квоты, чьи названия начинаются с `OPS-xxxx` (где `x` — цифра), в проект `OPS-xxxx`.
+Если проекта нет, он будет создан; если архивный — реактивирован.
 
-- Shared engineering rules: [bible/README.md](bible/README.md)
-- Project architecture: [bible-local/README.md](bible-local/README.md)
-- Release notes: `releases/<version>/RELEASE_NOTES.md`
+Сначала всегда смотрите preview:
 
-`bible-local/` is the source of truth for QuoteForge-specific architecture. If code changes behavior, update the matching file there in the same commit.
+```bash
+go run ./cmd/migrate_ops_projects
+```
 
-## Repository map
+Применение изменений:
+
+```bash
+go run ./cmd/migrate_ops_projects -apply
+```
+
+Без интерактивного подтверждения:
+
+```bash
+go run ./cmd/migrate_ops_projects -apply -yes
+```
+
+### Права БД для пользователя приложения
+
+#### Полный набор прав для обычного пользователя
+
+Чтобы выдать существующему пользователю все необходимые права (без переоздания):
+
+```sql
+-- Справочные таблицы (только чтение)
+GRANT SELECT ON RFQ_LOG.lot TO '<DB_USER>'@'%';
+GRANT SELECT ON RFQ_LOG.qt_lot_metadata TO '<DB_USER>'@'%';
+GRANT SELECT ON RFQ_LOG.qt_categories TO '<DB_USER>'@'%';
+GRANT SELECT ON RFQ_LOG.qt_pricelists TO '<DB_USER>'@'%';
+GRANT SELECT ON RFQ_LOG.qt_pricelist_items TO '<DB_USER>'@'%';
+
+-- Таблицы конфигураций и проектов (чтение и запись)
+GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_configurations TO '<DB_USER>'@'%';
+GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_projects TO '<DB_USER>'@'%';
+
+-- Таблицы синхронизации (только чтение для миграций, чтение+запись для статуса)
+GRANT SELECT ON RFQ_LOG.qt_client_local_migrations TO '<DB_USER>'@'%';
+GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_client_schema_state TO '<DB_USER>'@'%';
+GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_pricelist_sync_status TO '<DB_USER>'@'%';
+
+-- Применить изменения
+FLUSH PRIVILEGES;
+
+-- Проверка выданных прав
+SHOW GRANTS FOR '<DB_USER>'@'%';
+```
+
+#### Таблицы и их назначение
+
+| Таблица | Назначение | Права | Примечание |
+|---------|-----------|-------|-----------|
+| `lot` | Справочник компонентов | SELECT | Существующая таблица |
+| `qt_lot_metadata` | Расширенные данные компонентов | SELECT | Метаданные компонентов |
+| `qt_categories` | Категории компонентов | SELECT | Справочник |
+| `qt_pricelists` | Прайслисты | SELECT | Управляется сервером |
+| `qt_pricelist_items` | Позиции прайслистов | SELECT | Управляется сервером |
+| `qt_configurations` | Сохранённые конфигурации | SELECT, INSERT, UPDATE | Основная таблица работы |
+| `qt_projects` | Проекты | SELECT, INSERT, UPDATE | Для группировки конфигураций |
+| `qt_client_local_migrations` | Справочник миграций БД | SELECT | Только чтение (управляется админом) |
+| `qt_client_schema_state` | Состояние локальной схемы | SELECT, INSERT, UPDATE | Отслеживание примененных миграций |
+| `qt_pricelist_sync_status` | Статус синхронизации | SELECT, INSERT, UPDATE | Отслеживание активности синхронизации |
+
+#### При создании нового пользователя
+
+Если нужно создать нового пользователя с нуля:
+
+```sql
+-- 1) Создать пользователя
+CREATE USER IF NOT EXISTS 'quote_user'@'%' IDENTIFIED BY '<DB_PASSWORD>';
+
+-- 2) Выдать все необходимые права
+GRANT SELECT ON RFQ_LOG.lot TO 'quote_user'@'%';
+GRANT SELECT ON RFQ_LOG.qt_lot_metadata TO 'quote_user'@'%';
+GRANT SELECT ON RFQ_LOG.qt_categories TO 'quote_user'@'%';
+GRANT SELECT ON RFQ_LOG.qt_pricelists TO 'quote_user'@'%';
+GRANT SELECT ON RFQ_LOG.qt_pricelist_items TO 'quote_user'@'%';
+GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_configurations TO 'quote_user'@'%';
+GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_projects TO 'quote_user'@'%';
+GRANT SELECT ON RFQ_LOG.qt_client_local_migrations TO 'quote_user'@'%';
+GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_client_schema_state TO 'quote_user'@'%';
+GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_pricelist_sync_status TO 'quote_user'@'%';
+
+-- 3) Применить изменения
+FLUSH PRIVILEGES;
+
+-- 4) Проверить права
+SHOW GRANTS FOR 'quote_user'@'%';
+```
+
+#### 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@'%').
+
+### 4. Импорт метаданных компонентов
+
+```bash
+go run ./cmd/importer
+```
+
+### 5. Запуск
+
+```bash
+# Development
+go run ./cmd/qfs
+
+# Production (with Makefile - recommended)
+make build-release    # Builds with version info
+./bin/qfs -version    # Check version
+
+# Production (manual)
+VERSION=$(git describe --tags --always --dirty)
+CGO_ENABLED=0 go build -ldflags="-s -w -X main.Version=$VERSION" -o bin/qfs ./cmd/qfs
+./bin/qfs -version
+```
+
+**Makefile команды:**
+```bash
+make build-release   # Оптимизированная сборка с версией
+make build-all       # Сборка для всех платформ (Linux, macOS, Windows)
+make build-windows   # Только для Windows
+make run             # Запуск dev сервера
+make test            # Запуск тестов
+make install-hooks   # Установить git hooks (блокировка коммита с секретами)
+make clean           # Очистка bin/
+make help            # Показать все команды
+```
+
+Приложение будет доступно по адресу: http://localhost:8080
+
+### Локальная SQLite база (state)
+
+Локальная база приложения хранится в профиле пользователя и не зависит от расположения бинарника.
+Имя файла: `qfs.db`.
+
+- macOS: `~/Library/Application Support/QuoteForge/qfs.db`
+- Linux: `$XDG_STATE_HOME/quoteforge/qfs.db` (или `~/.local/state/quoteforge/qfs.db`)
+- Windows: `%LOCALAPPDATA%\\QuoteForge\\qfs.db`
+
+Можно переопределить путь через `-localdb` или переменную окружения `QFS_DB_PATH`.
+
+#### Sync readiness guard
+
+Перед `push/pull` выполняется preflight-проверка:
+- доступен ли сервер (MariaDB);
+- можно ли проверить и применить централизованные миграции локальной БД;
+- подходит ли версия приложения под `min_app_version` миграций.
+
+Если проверка не пройдена:
+- локальная работа (CRUD) продолжается;
+- sync API возвращает `423 Locked` с `reason_code` и `reason_text`;
+- в UI показывается красный индикатор и причина блокировки в модалке синхронизации.

 ```
+
+По сущностям:
+- Конфигурации: `Client <-> Server <-> Other Clients`
+- Проекты: `Client <-> Server <-> Other Clients`
+- Прайслисты: `Server -> Clients only` (локальный push отсутствует)
+- Локальная очистка прайслистов на клиенте: удаляются записи, которых нет на сервере и которые не используются активными локальными конфигурациями
+
+### Версионность конфигураций (local-first)
+
+Для `local_configurations` используется append-only versioning через полные snapshot-версии:
+
+- таблица: `local_configuration_versions`
+- для каждого изменения создаётся новая версия (`version_no = max + 1`)
+- `local_configurations.current_version_id` указывает на активную версию
+- старые версии не изменяются и не удаляются в обычном потоке
+- rollback не "перематывает" историю, а создаёт новую версию из выбранного snapshot
+
+При backfill (миграция `006_add_local_configuration_versions.sql`) для существующих конфигураций создаётся `v1` и проставляется `current_version_id`.
+
+#### Rollback
+
+Rollback выполняется API-методом:
+
+```bash
+POST /api/configs/:uuid/rollback
+{
+  "target_version": 3,
+  "note": "optional"
+}
+```
+
+Результат:
+- создаётся новая версия `vN` с `data` из целевой версии
+- `change_note = "rollback to v{target_version}"` (+ note, если передан)
+- `current_version_id` переключается на новую версию
+- конфигурация уходит в `sync_status = pending`
+
+### Локальный config.yaml
+
+По умолчанию `qfs` ищет `config.yaml` в той же user-state папке, где лежит `qfs.db` (а не рядом с бинарником).
+Если файла нет, он создаётся автоматически. Если формат устарел, он автоматически мигрируется в runtime-формат (`server` + `logging`).
+Можно переопределить путь через `-config` или `QFS_CONFIG_PATH`.

+### Краткая карта sync API
+
+| Endpoint | Назначение | Поток |
+|----------|------------|-------|
+| `POST /api/sync/push` | Отправить локальные pending-изменения | `SQLite -> MariaDB` |
+| `POST /api/sync/components` | Подтянуть справочник компонентов | `MariaDB -> SQLite` |
+| `POST /api/sync/pricelists` | Подтянуть прайслисты и позиции | `MariaDB -> SQLite` |
+| `POST /api/sync/all` | Полный цикл: push + pull + импорт проектов/конфигураций | `двунаправленно` |
+| `GET /api/sync/readiness` | Статус preflight/readiness | `read-only` |
+| `GET /api/sync/status` / `GET /api/sync/info` | Сводка статуса и данных синхронизации | `read-only` |
+
+#### Sync payload для versioning
+
+События в `pending_changes` для конфигураций содержат:
+- `configuration_uuid`
+- `operation` (`create` / `update` / `rollback`)
+- `current_version_id` и `current_version_no`
+- `snapshot` (текущее состояние конфигурации)
+- `idempotency_key` и `conflict_policy` (`last_write_wins`)
+
+Это позволяет push-слою отправлять на сервер актуальное состояние и готовит основу для будущего conflict resolution.
+
+## Разработка
+
+```bash
+# Запуск в режиме разработки (hot reload)

-# 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.
-
-## Tech stack

-# 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.
-- the available config types and their localized names flow from `qt_settings.config_types` on the server;
-  QF falls back to hardcoded "server/Сервер" and "storage/СХД" when the setting is absent.
-
-## Server-driven configurator settings (`qt_settings`)
-
-QF reads four settings from `qt_settings` (MariaDB) and caches them in `local_qt_settings` (SQLite).
-They are synced during every component sync. See `bible-local/server-contract-qt-settings.md` for the
-full contract and JSON schemas.
-
-| Setting key | Effect in QF |
-|-------------|-------------|
-| `config_types` | New-config modal buttons; category allowlist per config type |
-| `tab_config` | Configurator tab structure, sections, singleSelect |
-| `always_visible_tabs` | Which tabs are shown even when empty |
-| `required_categories` | Per-config-type badge on tabs with unfilled required categories |
-
-Rules:
-- sync runs after `SyncComponents`; failure is non-fatal (Warn log only);
-- `local_qt_settings` is a read-only cache — never written by user actions;
-- absent or unparseable settings: QF uses hardcoded fallbacks for that key only;
-- `config_types[].categories` is an allowlist: a category absent from all types is shown everywhere;
-- `qt_categories.name` and `qt_categories.name_ru` are not used by QF runtime; do not depend on them.
-
-## 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 |
-| `local_qt_settings` | server-pushed configurator settings cache (from `qt_settings`) |
-
-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 (note: `name`/`name_ru` columns being removed; QF does not use them)
-- `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
-- `qt_settings` — server-pushed configurator settings; schema managed by server-side agent (see `bible-local/server-contract-qt-settings.md`)
-
-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; `lot_suggestion` column updated when user manually maps PN → LOT in vendor-spec UI
-
-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.

-
-Rules:
-- `qt_client_schema_state` requires INSERT + UPDATE for sync status tracking (uses `ON DUPLICATE KEY UPDATE`);
-- `qt_vendor_partnumber_seen` requires INSERT + UPDATE (vendor PN discovery during sync);
-- no DELETE is needed on sync/tracking tables — rows are never removed by the client;
-- `lot` SELECT is required for the connection validation probe in `/setup`;
-- the setup page shows `can_write: true` only when `qt_client_schema_state` INSERT succeeds.
-
-## Migrations
-
-SQLite:
-- schema creation and additive changes go through GORM `AutoMigrate`;
-- data fixes, index repair, and one-off rewrites go through `runLocalMigrations`;
-- local migration state is tracked in `local_schema_migrations`.
-
-MariaDB:
-- SQL files live in `migrations/`;

-## 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 |
-| --- | --- |

-| `-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
-|PowerSupply_1300W_Titanium_220VACor240VDC_GaN*2
-```
-
-Rules:
-- the entire file becomes a single configuration (`server_count = 1`);
-- configuration `name` is derived from the uploaded filename (without extension);
-- lines that do not contain `*<digits>` are skipped;
-- no price data is present in the format; `unit_price` and `total_price` are left nil.
-
-## Text BOM import
-
-The same endpoint `POST /api/projects/:uuid/vendor-import` also accepts a human-readable Russian text BOM.
-
-Format: an optional header line ending with `, в составе:` followed by one component per line as
-`<description> - <quantity> шт.`. The separator may be a hyphen, en-dash, or em-dash; the space before
-`шт` is optional; a trailing `.` after `шт` is optional. Quantities are anchored to the end of the line,
-so hyphens, commas, and digits inside the description (e.g. `8-GPU-2304GB`, `RAID0,1,10`) are preserved.
-
-Example:
-```
-Вычислительный GPU сервер G5500V7, в составе:
-GPU-NVIDIA HGX B300 8-GPU-2304GB HBM3E - 1 шт.
-CPU Intel 6760P Xeon 2.2GHz 64C 320M 330W - 2 шт.
-Mem 128G DDR5-6400MHz ECC-RDIMM - 16 шт.
-NVIDIA twin port transceiver, 800Gbps, OSFP - 8шт.
-```
-
-Rules:
-- the entire file becomes a single configuration (`server_count = 1`);
-- the header (any line ending with `, в составе:`) supplies `server_model` and `name`; the model is the
-  last whitespace-separated token before the comma (so both `Сервер X3` and `Вычислительный GPU сервер X3`
-  resolve to `X3`);
-- without a header, `name` falls back to the uploaded filename (without extension) and `server_model` is empty;
-- each line is trimmed, so leading/trailing whitespace never enters `vendor_partnumber`;
-- the format carries no partnumbers — each line's description is stored as both `vendor_partnumber` and
-  `description`, so rows resolve through the active partnumber book when matched and otherwise stay
-  unresolved and editable in the UI;
-- lines that do not match `<description> - <quantity> шт.` are skipped;
-- no price data is present in the format; `unit_price` and `total_price` are left nil.
-
-## Nx BOM import (quantity-first)
-
-The same endpoint `POST /api/projects/:uuid/vendor-import` also accepts a quantity-first BOM
-where each item line begins with `<qty>x <description>`.
-
-Format: an optional header line ending with `, в составе:` followed by one component per line as
-`<qty>x <description>`. The `x` separator is case-insensitive; parentheses, commas, and hyphens
-inside the description are preserved as-is.
-
-Example:
-```
-Сервер G893-SD1-AAX3, в составе:
-1x 8U 2CPU 8GPU Server System (32x DDR5 DIMM Slots,8x 2.5" Hot-Swap Drive Bays, 4+4 3000W, 2x 10Gb/s RJ45, 2x IPMI RJ45)

-  last whitespace-separated token before the comma;
-- without a header, `name` falls back to the uploaded filename (without extension) and `server_model` is empty;
-- the format carries no partnumbers — each line's description is stored as both `vendor_partnumber` and
-  `description`, so rows resolve through the active partnumber book when matched and otherwise stay
-  unresolved and editable in the UI;
-- lines that do not match `<qty>x <description>` are skipped;
-- no price data is present in the format; `unit_price` and `total_price` are left nil;
-- detection runs before Text BOM in the format switch (Inspur → Nx → Text).
-
-## Pasted BOM text parsing
-
-`POST /api/vendor-spec/parse-text` is a stateless endpoint that parses pasted single-column text BOM
-(Inspur and Russian text BOM) into rows. Request body: `{"text": "..."}`. Response:
-`{"rows": [{vendor_partnumber, quantity, description}], "format": "Inspur"|"Text"|""}`.
-
-This shares the exact detectors and parsers used by the file-import path
-(`ParsePastedBOMText` → `IsInspurBOM`/`parseInspurBOM`, `IsNxBOM`/`parseNxBOM`, `IsTextBOM`/`parseTextBOM`),
-so paste and upload behave identically — there is no second parser in the frontend. The configurator's BOM
-paste box calls this endpoint; an empty `rows` result (or any payload containing tabs, i.e. a real
-spreadsheet table) falls back to the manual column-mapping grid.

-# 10 - Agent API Guide: Pricing Servers from a TZ
-
-This guide is written for an AI agent that needs to price a server configuration
-(техническое задание, ТЗ) using the QuoteForge HTTP API.
-
-## Runtime assumptions
-
-- QuoteForge runs locally, binds to `127.0.0.1:8080` by default.
-- No authentication is required — the app is single-user, loopback-only.
-- All responses are JSON. All request bodies are JSON unless stated otherwise.
-- The port can be overridden with the `QF_SERVER_PORT` environment variable.
-
-Base URL for all examples: `http://127.0.0.1:8080`

-## Configuration composition rules
-
-These rules are mandatory and must be respected before saving any configuration.
-
-### 1. Every configuration must belong to a project
-
-Configurations cannot be created in isolation. The correct sequence is:
-
-1. Create a project (`POST /api/projects`) and save the returned `uuid`.
-2. Create the configuration inside that project by passing `project_uuid` in the
-   config body, or by using `POST /api/projects/:uuid/configs`.
-
-If the project for a given TZ already exists, retrieve its `uuid` first:
-```
-GET /api/projects?page=1&per_page=100
-```
-then pass the matching `uuid` in `project_uuid`.
-
-### 2. Every server configuration must contain all four required component groups
-
-A configuration is not valid for pricing unless items from all four of the
-following category groups are present:
-
-| Category code | Meaning          | Notes                                             |
-|---------------|------------------|---------------------------------------------------|
-| `MB`          | Motherboard      | exactly one MB per configuration                  |
-| `CPU`         | Processor        | one or more CPUs                                  |
-| `MEM`         | Memory / RAM     | one or more memory modules                        |
-| `PS` / `PSU`  | Power supply     | `PSU` is the current code; `PS` is legacy — both are accepted |
-
-Before saving, verify the assembled BOM with `POST /api/quote/validate`:
-the response `errors` array will contain `"Component not found: …"` entries
-for unknown lot names, and `warnings` will list lots without a price.
-Reject the configuration and report back to the user if any of the four
-required categories is missing.
-
-### 3. Category codes to use when searching
-
-Use `category=<code>` in `GET /api/components` to narrow results:
-
-```
-GET /api/components?category=MB&search=X13&has_price=true
-GET /api/components?category=CPU&search=Xeon+Gold&has_price=true
-GET /api/components?category=MEM&search=32GB+DDR5&has_price=true
-GET /api/components?category=PSU&search=800W&has_price=true
-```
-
-Retrieve the full list of active categories at any time:
-```
-GET /api/categories
-```
-
----
-
-## Typical workflow for pricing a server
-
-```
-1.  Check the app is up                 GET  /api/ping
-2.  Find or create a project            GET  /api/projects  →  POST /api/projects
-3.  Find the latest pricelist           GET  /api/pricelists/latest?source=estimate
-4.  Look up lot names for MB            GET  /api/components?category=MB&search=…
-5.  Look up lot names for CPU           GET  /api/components?category=CPU&search=…
-6.  Look up lot names for MEM           GET  /api/components?category=MEM&search=…
-7.  Look up lot names for PSU           GET  /api/components?category=PSU&search=…
-8.  (Repeat for other components)       GET  /api/components?category=…&search=…
-9.  Validate and calculate the quote    POST /api/quote/validate
-10. (Optional) Compare price tiers      POST /api/quote/price-levels
-11. Save configuration in the project   POST /api/projects/:uuid/configs
-```
-
----
-
-## Step 1 — Verify the app is running
-
-```
-GET /api/ping
-```
-
-Response `200 OK`:
-```json
-{"status": "ok"}
-```
-
----
-
-## Step 2 — Find or create a project
-
-Each TZ maps to one project. Use the TZ identifier as the `code` field.
-
-### Find an existing project
-
-```
-GET /api/projects?page=1&per_page=100
-```
-
-Response `200 OK`:
-```json
-{
-  "projects": [
-    {
-      "uuid": "aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee",
-      "code": "TZ-123",
-      "variant": "",
-      "name": "Проект по ТЗ №123",
-      "tracker_url": "",
-      "is_active": true,
-      "created_at": "2026-06-01T00:00:00Z"
-    }
-  ],
-  "total": 1,
-  "page": 1,
-  "per_page": 100
-}
-```
-
-### Create a new project
-
-```
-POST /api/projects
-Content-Type: application/json
-```
-
-Request body:
-```json
-{
-  "code": "TZ-123",
-  "name": "Проект по ТЗ №123",
-  "tracker_url": ""
-}
-```
-
-Fields:
-
-| field         | type   | required | description                                                        |
-|---------------|--------|----------|--------------------------------------------------------------------|
-| `code`        | string | yes      | short identifier, unique per variant; use the TZ number or ticket  |
-| `variant`     | string | no       | variant label within the same `code`; default is empty string      |
-| `name`        | string | no       | human-readable title                                               |
-| `tracker_url` | string | no       | link to a ticket or issue tracker                                  |
-
-Response `201 Created`:
-```json
-{
-  "uuid": "aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee",
-  "code": "TZ-123",
-  "variant": "",
-  "name": "Проект по ТЗ №123",
-  "is_active": true,
-  "created_at": "2026-06-11T10:00:00Z"
-}
-```
-
-Save the `uuid` — it is required to create configurations inside this project.
-
----
-
-## Step 3 — Find the latest pricelist
-
-QuoteForge maintains three pricing tiers. The `source` values are:
-
-| source       | meaning                     |
-|--------------|-----------------------------|
-| `estimate`   | list / catalogue price      |
-| `warehouse`  | stock price (purchase cost) |
-| `competitor` | competitor reference price  |
-
-```
-GET /api/pricelists/latest?source=estimate
-```
-
-Response `200 OK`:
-```json
-{
-  "id": 42,
-  "source": "estimate",
-  "version": "2026-05-28",
-  "item_count": 12500,
-  "is_active": true,
-  "created_at": "2026-05-28T06:00:00Z"
-}
-```
-
-The `id` field is a numeric pricelist identifier. Pass it as `pricelist_id`
-when calculating a quote to pin pricing to a specific pricelist.
-
-To list all available pricelists:
-```
-GET /api/pricelists?source=estimate&active_only=true
-```
-
----
-
-## Steps 4–8 — Look up component lot names
-
-Each component is identified by a `lot_name` (internal SKU). The TZ typically
-contains model names or descriptions; use the search endpoint to resolve them.
-
-```
-GET /api/components?search=Xeon+Gold+6342&category=CPU&has_price=true&page=1&per_page=20
-```
-
-Query parameters:
-
-| parameter        | default | description                                       |
-|------------------|---------|---------------------------------------------------|
-| `search`         | —       | free-text search in lot name and description      |
-| `category`       | —       | filter by category code (`MB`, `CPU`, `MEM`, `PSU`, …) |
-| `has_price`      | false   | return only components that have a price          |
-| `include_hidden` | false   | include hidden/retired components                 |
-| `page`           | 1       | page number                                       |
-| `per_page`       | 20      | page size                                         |
-
-Response `200 OK`:
-```json
-{
-  "components": [
-    {
-      "lot_name": "CPU-XEON-6342",
-      "description": "Intel Xeon Gold 6342, 24C/48T, 2.8 GHz, LGA4189",
-      "category": "CPU",
-      "category_name": "CPU",
-      "model": "Xeon Gold 6342"
-    }
-  ],
-  "total": 1,
-  "page": 1,
-  "per_page": 20
-}
-```
-
-To look up a single component by exact lot name:
-```
-GET /api/components/CPU-XEON-6342
-```
-
-To list all known categories:
-```
-GET /api/categories
-```
-
----
-
-## Step 9 — Validate and calculate the quote
-
-Before saving, validate the assembled BOM. This catches unknown lot names and
-missing prices, and also confirms that all required categories are covered.
-
-```
-POST /api/quote/validate
-Content-Type: application/json
-```
-
-Request body:
-```json
-{
-  "items": [
-    {"lot_name": "MB-X13DAI-N",        "quantity": 1},
-    {"lot_name": "CPU-XEON-6342",       "quantity": 2},
-    {"lot_name": "RAM-32GB-DDR4-3200",  "quantity": 8},
-    {"lot_name": "SSD-480GB-SATA",      "quantity": 2},
-    {"lot_name": "PSU-800W-TITANIUM",   "quantity": 2}
-  ],
-  "pricelist_id": 42
-}
-```
-
-Response `200 OK`:
-```json
-{
-  "valid": true,
-  "items": [
-    {
-      "lot_name": "MB-X13DAI-N",
-      "quantity": 1,
-      "unit_price": 95000.00,
-      "total_price": 95000.00,
-      "description": "Supermicro X13DAi-N dual-socket server board",
-      "category": "MB",
-      "has_price": true
-    },
-    {
-      "lot_name": "CPU-XEON-6342",
-      "quantity": 2,
-      "unit_price": 87500.00,
-      "total_price": 175000.00,
-      "description": "Intel Xeon Gold 6342, 24C/48T, 2.8 GHz",
-      "category": "CPU",
-      "has_price": true
-    },
-    {
-      "lot_name": "RAM-32GB-DDR4-3200",
-      "quantity": 8,
-      "unit_price": 12000.00,
-      "total_price": 96000.00,
-      "description": "32 GB DDR4-3200 ECC RDIMM",
-      "category": "MEM",
-      "has_price": true
-    },
-    {
-      "lot_name": "PSU-800W-TITANIUM",
-      "quantity": 2,
-      "unit_price": 18500.00,
-      "total_price": 37000.00,
-      "description": "800W 80+ Titanium redundant PSU",
-      "category": "PSU",
-      "has_price": true
-    }
-  ],
-  "errors": [],
-  "warnings": [],
-  "total": 403000.00
-}
-```
-
-**Agent check after validation:**
-
-1. `valid` must be `true` — all lot names resolved.
-2. `errors` must be empty — no unknown components.
-3. The returned `items` array must contain at least one entry from each required
-   category: `MB`, `CPU`, `MEM`, and `PS` or `PSU`.
-4. Items with `has_price: false` are allowed but should be flagged to the user.
-
-If any check fails, do not save the configuration. Report the issue and ask the
-user to clarify or replace the problematic component.
-
-For simple price totals without validation metadata use `POST /api/quote/calculate`
-— identical request body, response contains only `items` and `total`.
-
----
-
-## Step 10 (optional) — Compare price tiers
-
-To see estimate, warehouse, and competitor prices side-by-side for a BOM:
-
-```
-POST /api/quote/price-levels
-Content-Type: application/json
-```
-
-Request body:
-```json
-{
-  "items": [
-    {"lot_name": "CPU-XEON-6342", "quantity": 2},
-    {"lot_name": "RAM-32GB-DDR4-3200", "quantity": 8}
-  ],
-  "pricelist_ids": {
-    "estimate": 42,
-    "warehouse": 31,
-    "competitor": 15
-  },
-  "no_cache": false
-}
-```
-
-`pricelist_ids` is optional. When omitted the latest pricelist for each source
-is used automatically.
-
-Response `200 OK`:
-```json
-{
-  "items": [
-    {
-      "lot_name": "CPU-XEON-6342",
-      "quantity": 2,
-      "estimate_price": 87500.00,
-      "warehouse_price": 71000.00,
-      "competitor_price": 85000.00,
-      "delta_wh_estimate_abs": -16500.00,
-      "delta_wh_estimate_pct": -18.86,
-      "delta_comp_estimate_abs": -2500.00,
-      "delta_comp_estimate_pct": -2.86,
-      "delta_comp_wh_abs": 14000.00,
-      "delta_comp_wh_pct": 19.72,
-      "price_missing": []
-    }
-  ],
-  "resolved_pricelist_ids": {
-    "estimate": 42,
-    "warehouse": 31,
-    "competitor": 15
-  }
-}
-```
-
-`price_missing` lists the source names for which no price was found for that lot.
-Delta fields are `null` when either operand price is missing.
-
----
-
-## Step 11 — Save a configuration inside the project
-
-Use the project-scoped endpoint so the configuration is immediately linked to
-the correct project without a separate move operation.
-
-```
-POST /api/projects/:project_uuid/configs
-Content-Type: application/json
-```
-
-The request body is identical to `POST /api/configs` — the `project_uuid` field
-in the body is ignored when using the project-scoped route; the URL parameter
-takes precedence.
-
-Request body:
-```json

-# 11 - Lot Suggestions (qt_vendor_partnumber_seen)
-
-## Purpose
-
-`qt_vendor_partnumber_seen` records vendor partnumbers encountered during import
-that have no mapping in the active partnumber book. When a user manually maps
-such a partnumber to one or more LOT names in the QuoteForge UI, those mappings
-are written back to the server as **lot suggestions** — hints for the team that
-maintains `qt_partnumber_book_items`.
-
-## Schema Extension
-
-Add one nullable column to `qt_vendor_partnumber_seen`:
-
-```sql
-ALTER TABLE `qt_vendor_partnumber_seen`
-  ADD COLUMN `lot_suggestion` longtext DEFAULT NULL
-    COMMENT 'JSON array [{lot_name, qty}] — user-entered LOT mappings from the UI';
-```
-
-### Updated table contract (relevant columns only)
-
-| Column | Type | Notes |
-|--------|------|-------|
-| `partnumber` | varchar(255) UNIQUE NOT NULL | natural key |
-| `lot_suggestion` | longtext (JSON) | nullable; set when user maps the PN manually |
-
-`lot_suggestion` contains the same JSON shape as `qt_partnumber_book_items.lots_json`:
-
-```json
-[
-  { "lot_name": "LOT_A", "qty": 1 },
-  { "lot_name": "LOT_B", "qty": 2 }
-]
-```
-
-Rules:
-- `null` or absent means no suggestion has been entered yet;
-- an empty array `[]` is not a valid value — use `null` instead;
-- a single PN may map to multiple lots (`lot_name` entries), each with its own `qty`;
-- the array is ordered — the order reflects the order of `lot_mappings[]` in the
-  vendor spec row at the time of last user save;
-- `qty` must be a positive integer (≥ 1).
-
-## Write Contract (QuoteForge → MariaDB)
-
-QuoteForge writes `lot_suggestion` when all of the following are true:
-
-1. The user saves a vendor BOM via `PUT /api/configs/:uuid/vendor-spec`.
-2. At least one `vendor_spec` row has a non-empty `lot_mappings[]` array (manually
-   entered or confirmed by the user — not auto-resolved from a partnumber book).
-3. The MariaDB connection is available at the time of save.
-
-For each such row:
-
-```sql
-INSERT INTO qt_vendor_partnumber_seen
-    (source_type, vendor, partnumber, description, is_ignored, last_seen_at, lot_suggestion)
-VALUES
-    ('manual', '', ?, ?, 0, NOW(3), ?)
-ON DUPLICATE KEY UPDATE
-    lot_suggestion = VALUES(lot_suggestion),
-    last_seen_at   = IF(lot_suggestion IS NULL, last_seen_at, NOW(3))
-```
-
-- `lot_suggestion` value = JSON-marshalled `lot_mappings[]` from the vendor spec item,
-  reusing the same `{lot_name, qty}` shape.
-- If the PN row already exists and `lot_suggestion` is already set, it is **overwritten**
-  with the latest user input (the user is assumed to have corrected it).
-- If the user **clears** all lot_mappings for a PN (sets to empty), no update is sent —
-  the existing `lot_suggestion` on the server is left untouched.
-- Rows where `lot_mappings[]` is empty or nil are skipped entirely (no insert, no update).
-- Writes are best-effort: a MariaDB error for one row is logged and skipped; remaining
-  rows continue. A write failure does not fail the vendor-spec save.
-
-## Read Contract (Partnumber-Book Creation Tool → MariaDB)
-
-The tool that maintains `qt_partnumber_book_items` reads `qt_vendor_partnumber_seen`
-to discover new partnumbers and their suggested mappings.
-
-### Discovery query
-
-```sql
-SELECT
-    s.id,
-    s.partnumber,
-    s.description,
-    s.vendor,
-    s.lot_suggestion,
-    s.last_seen_at,
-    b.lots_json AS book_lots_json
-FROM qt_vendor_partnumber_seen s
-LEFT JOIN qt_partnumber_book_items b ON b.partnumber = s.partnumber
-WHERE s.is_ignored = 0
-  AND s.lot_suggestion IS NOT NULL
-ORDER BY s.last_seen_at DESC;
-```
-
-### Interpretation rules
-
-| Condition | Meaning | Suggested action |
-|-----------|---------|-----------------|
-| `book_lots_json IS NULL` AND `lot_suggestion IS NOT NULL` | No book entry yet; user suggested mapping | Create new `qt_partnumber_book_items` row with `lots_json = lot_suggestion` |
-| `book_lots_json IS NOT NULL` AND `lot_suggestion IS NOT NULL` AND they differ | User corrected or extended the existing mapping | Review diff and decide whether to update `qt_partnumber_book_items` |
-| `book_lots_json IS NOT NULL` AND `lot_suggestion IS NOT NULL` AND they match | Suggestion already applied | No action needed |
-
-### Suggestion format
-
-`lot_suggestion` is valid JSON (or `null`). Parse it as an array of objects:
-
-```json
-[
-  { "lot_name": "LOT_A", "qty": 1 },
-  { "lot_name": "LOT_B", "qty": 2 }
-]
-```
-
-Map directly to `qt_partnumber_book_items.lots_json` — the formats are identical.
-
-### Multiple lots per PN
-
-One PN may have multiple suggestion entries (e.g., a bundle). The array carries
-all of them. The book-creation tool must preserve the full array when writing
-`lots_json`, not just the first element.
-
-### Qty semantics
-
-`qty` in a lot suggestion means "how many of this LOT per one occurrence of the
-vendor PN". This matches `qt_partnumber_book_items.lots_json` exactly. Example:
-a server platform that comes with 4 PSUs would produce
-`[{"lot_name": "PS_1300W_Titanium", "qty": 4}]`.
-
-## Permissions
-
-The existing `qfs_user` grant covers this column — no new permission is required:
-
-```sql
-GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_vendor_partnumber_seen TO 'qfs_user'@'%';
-```
-
-The book-creation tool connects with its own credentials and needs at minimum:
-
-```sql
-GRANT SELECT ON RFQ_LOG.qt_vendor_partnumber_seen TO '<book_tool_user>'@'%';
-GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_partnumber_book_items TO '<book_tool_user>'@'%';
-```
-
-## Migration
-
-Migration is applied outside this repo (server-side DDL):
-
-```sql
-ALTER TABLE `qt_vendor_partnumber_seen`
-  ADD COLUMN IF NOT EXISTS `lot_suggestion` longtext DEFAULT NULL
-    COMMENT 'JSON [{lot_name, qty}] — user LOT suggestions from QuoteForge UI';
-```
-
-QuoteForge handles a missing column gracefully: if the migration has not run yet,
-the write with `lot_suggestion` fails with "Unknown column" (MariaDB 1054), a warning
-is logged, and the row is re-inserted without the column. The app never crashes on
-migration lag.

-# Runtime Flows
-
-Critical mutation paths, deduplication logic, and cross-entity side effects.
-Update this file in the same commit as any change to the flows below.
-
----
-
-## 1. Configuration save (create/update)
-
-1. Handler receives JSON body; validates via `ShouldBindJSON`.
-2. `LocalConfigurationService.Create` or `Update` is called.
-3. Service computes `total_price` from `req.Items.Total()` (sum of `unit_price * quantity` per item).
-4. A new revision snapshot is created via `createWithVersion`; revision number increments.
-5. `quoteService.RecordUsage` is called best-effort (warn on failure, do not abort save).
-6. Configuration row written to SQLite (`local_configurations`); version row appended to `local_configuration_versions`.
-7. Pending change queued in `pending_changes` for later sync push.
-
-**DO NOT** read prices from `local_components` during save - prices must already be on items.
-**DO NOT** skip version creation on rename/reorder/project-move - those operations call different paths that must NOT call `createWithVersion`.
-
----
-
-## 2. Refresh prices (POST /api/configs/:uuid/refresh-prices)
-
-1. Handler calls `LocalConfigurationService.RefreshPricesNoAuth(uuid, pricelistServerID)`.
-2. If online, `SyncPricelistsIfNeeded` runs best-effort (warn on failure, do not block).
-3. Resolves target pricelist in order:
-   a. Explicitly requested pricelist (`pricelistServerID` param).
-   b. Pricelist stored in configuration row (`localCfg.PricelistID`).
-   c. Latest local pricelist as fallback.
-4. For each item in the config, looks up price from `local_pricelist_items` via `GetLocalPricesForLots` (batch, single query).
-5. Items with matching prices are updated; items with no price keep their existing `unit_price`.
-6. Updated configuration saved as a new version (same flow as §1 from step 4 onward).
-
-**DO NOT** read prices from `qt_pricelist_items` (MariaDB) directly - prices come from SQLite cache only.
-
----
-
-## 3. Pricelist sync (POST /api/sync/pricelists)
-
-1. Readiness guard checked; returns 423 if guard blocks sync.
-2. `SyncService.SyncPricelists` pulls from `qt_pricelists` and `qt_pricelist_items` (MariaDB).
-3. For each pricelist: header upserted first, then items replaced atomically via `ReplaceLocalPricelistItems`.
-4. After all pricelists: `RecalculateAllLocalPricelistUsage` marks which pricelists are referenced by active configurations.
-5. Sync result (status, error, timestamp) written to `app_settings` via `SetPricelistSyncResult`.
-
-**DO NOT** write pricelist header without items in the same transaction - must be atomic.
-**DO NOT** query MariaDB from runtime handlers outside sync/setup flows.
-
----
-
-## 4. Vendor spec apply (POST /api/configs/:uuid/vendor-spec/apply)
-
-1. Incoming `items[]` (lot_name, quantity, unit_price) replace the configuration's `items` entirely.
-2. New item list saved through `LocalConfigurationService.UpdateItemsNoAuth`.
-3. A new revision is created reflecting the BOM-derived item state.
-
-**DO NOT** apply vendor spec without going through the service layer - handler must not write items directly to DB.
-
----
-
-## 5. Configuration versioning invariants
-
-- `local_configuration_versions` is append-only; rows are never updated or deleted.
-- Version deduplication: if new snapshot hash equals current head, no new version is created.
-- Rollback = create new HEAD revision from old snapshot data (does not restore version pointer to old row).
-- UI must always show "main" (implicit head) as the active state; never point to a numbered revision after save.
-- Operations that do NOT create a new version: rename, reorder within project, project move, pricelist selector change only.
-
----
-
-## 6. Pending changes queue
-
-- Every local write (create/update/delete) appends a row to `pending_changes`.
-- `POST /api/sync/push` drains the queue by writing to MariaDB.
-- If a push fails, `increment_attempts` and `last_error` are updated; row stays in queue.
-- `RepairPendingChanges` reconciles orphaned changes (configuration/project deleted locally).
-
----
-
-## 7. Error handling boundary rules
-
-- Handlers: log 500 responses with `slog.Error`; surface error message via `RespondError`.
-- Services: wrap errors with `fmt.Errorf("context: %w", err)`; do NOT log inside service.
-- Repositories: return raw errors; no logging.
-- Best-effort operations (usage stats, background sync): log `slog.Warn` and continue.

-# Server contract: qt_settings
-
-## Purpose
-
-`qt_settings` is a general-purpose key→JSON-value table that the price management
-application uses to push configuration into QuoteForge clients. QF reads it during
-component sync and caches the result in `local_qt_settings` (SQLite).
-
-## Required MariaDB changes (implemented by server-side agent)
-
-```sql
-CREATE TABLE IF NOT EXISTS qt_settings (
-    name  VARCHAR(100) NOT NULL PRIMARY KEY,
-    value TEXT         NOT NULL   -- JSON-encoded value
-) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
-
-GRANT SELECT ON RFQ_LOG.qt_settings TO 'qfs_user'@'%';
-```
-
-## Settings consumed by QuoteForge
-
-All values are JSON. Missing or unparseable entries are silently skipped; QF
-falls back to hardcoded defaults for each missing key.
-
----
-
-### `config_types`
-
-Defines the available device configuration types, their localized names, and the
-category codes that are allowed for each type. QF uses this for:
-- the new-config modal (button list + labels);
-- the configurator's category filter per `config_type`.
-
-**Value format:** JSON array of objects.
-
-```json
-[
-  {
-    "code":          "server",
-    "name_ru":       "Сервер",
-    "display_order": 10,
-    "categories":    [
-      "MB","CPU","MEM","RAID",

-      "SSD","HDD","M2","EDSFF","HHHL",
-      "NIC","HBA","HCA","ACC","CARD"
-    ]
-  }
-]
-```
-
-Fields:
-| Field | Type | Description |
-|-------|------|-------------|
-| `code` | string | Identifier stored on `qt_configurations.config_type`. Must be stable. |
-| `name_ru` | string | Display name in Russian for the QF UI. |
-| `display_order` | int | Sort order for the modal button list. |
-| `categories` | string[] | Allowlist of LOT category codes visible in this config type. A category absent from ALL entries is visible in all types. |
-
----
-
-### `tab_config`
-
-Defines the configurator tab layout: which tabs exist, which categories each tab
-contains, optional sub-sections within a tab, and whether the tab uses
-single-select mode.
-
-**Value format:** JSON array of tab objects (ordered — defines tab bar order).
-
-```json
-[
-  {
-    "key":           "base",
-    "label":         "Base",
-    "single_select": true,
-    "categories":    ["MB","CPU","MEM","ENC","DKC","CTL"],

-      { "title": "Диски",            "categories": ["M2","SSD","HDD","EDSFF","HHHL"] }
-    ]
-  },

-  { "key": "sw",          "label": "SW",          "single_select": false, "categories": ["SW"] }
-]
-```
-
-The QF frontend always appends an "other" tab for any categories not listed here.
-
----
-
-### `always_visible_tabs`
-
-Tab keys that are always shown in the configurator regardless of whether they
-contain any items. Other tabs are hidden when empty.
-
-**Value format:** JSON string array.
-
-```json
-["base", "storage", "pci"]
-```
-
----
-
-### `required_categories`
-
-Category codes that must have at least one LOT selected for a configuration to
-be considered complete. Keyed by `config_type` code. QF uses this to show a
-badge on the tab label when required categories are missing.
-
-**Value format:** JSON object mapping config_type code → string array.
-
-```json
-{
-  "server":  ["CPU", "MEM", "BB"],
-  "storage": ["DKC", "CPU", "MEM"]
-}
-```
-
----
-
-## Backward compatibility
-
-- If `qt_settings` does not exist (old server): QF logs `Warn` during sync and
-  leaves `local_qt_settings` empty. The frontend falls back to hardcoded defaults
-  for all four settings. No crash, no data loss.
-- If a specific key is absent from `qt_settings`: QF falls back to the hardcoded
-  default for that key only.
-- Old QF clients that do not know about `local_qt_settings` continue to use their
-  hardcoded JS constants unchanged.
-
-## Note on `qt_categories`
-
-`qt_categories.name` and `qt_categories.name_ru` are being removed.
-QF runtime does not depend on them — `GetCategories` derives `Name` from the
-category code string stored in `local_components`.

+# CSV Export Pattern (Go + GORM)
+
+## Архитектура (3-слойная)
+
+### 1. Handler Layer (HTTP)
+**Задачи**: Обработка HTTP-запроса, установка заголовков, инициация экспорта
+
+```go
+func (h *PricelistHandler) ExportCSV(c *gin.Context) {
+    // 1. Валидация параметров
+    id, err := strconv.ParseUint(c.Param("id"), 10, 32)
+
+    // 2. Получение метаданных для формирования имени файла
+    pl, err := h.service.GetByID(uint(id))
+
+    // 3. Установка HTTP-заголовков для скачивания
+    filename := fmt.Sprintf("pricelist_%s.csv", pl.Version)
+    c.Header("Content-Type", "text/csv; charset=utf-8")
+    c.Header("Content-Disposition", fmt.Sprintf("attachment; filename=\"%s\"", filename))
+
+    // 4. UTF-8 BOM для Excel-совместимости
+    c.Writer.Write([]byte{0xEF, 0xBB, 0xBF})
+
+    // 5. Настройка CSV writer
+    writer := csv.NewWriter(c.Writer)
+    writer.Comma = ';'  // Точка с запятой для Excel
+    defer writer.Flush()
+
+    // 6. Динамические заголовки (зависят от типа данных)
+    isWarehouse := strings.ToLower(pl.Source) == "warehouse"
+    var header []string
+    if isWarehouse {
+        header = []string{"Артикул", "Категория", "Описание", "Доступно", "Partnumbers", "Цена, $", "Настройки"}
+    } else {
+        header = []string{"Артикул", "Категория", "Описание", "Цена, $", "Настройки"}
+    }
+    writer.Write(header)
+
+    // 7. Streaming в batches через callback
+    err = h.service.StreamItemsForExport(uint(id), 500, func(items []models.PricelistItem) error {
+        for _, item := range items {
+            row := buildRow(item, isWarehouse)
+            if err := writer.Write(row); err != nil {
+                return err
+            }
+        }
+        writer.Flush()  // Flush после каждого batch
+        return nil
+    })
+}
+```
+
+### 2. Service Layer
+**Задачи**: Оркестрация, делегирование в репозиторий
+
+```go
+func (s *Service) StreamItemsForExport(pricelistID uint, batchSize int, callback func(items []models.PricelistItem) error) error {
+    if s.repo == nil {
+        return fmt.Errorf("offline mode: cannot stream pricelist items")
+    }
+    return s.repo.StreamItemsForExport(pricelistID, batchSize, callback)
+}
+```
+
+### 3. Repository Layer (Критичный)
+**Задачи**: Batch-загрузка из БД, оптимизация запросов, enrichment
+
+```go
+func (r *PricelistRepository) StreamItemsForExport(pricelistID uint, batchSize int, callback func(items []models.PricelistItem) error) error {
+    if batchSize <= 0 {
+        batchSize = 500  // Default batch size
+    }
+
+    // Проверка типа pricelist для conditional enrichment
+    var pl models.Pricelist
+    isWarehouse := false
+    if err := r.db.Select("source").Where("id = ?", pricelistID).First(&pl).Error; err == nil {
+        isWarehouse = pl.Source == string(models.PricelistSourceWarehouse)
+    }
+
+    offset := 0
+    for {
+        var items []models.PricelistItem
+
+        // ⚡ КЛЮЧЕВОЙ МОМЕНТ: JOIN для избежания N+1 запросов
+        err := r.db.Table("qt_pricelist_items AS pi").
+            Select("pi.*, COALESCE(l.lot_description, '') AS lot_description, COALESCE(l.lot_category, '') AS category").
+            Joins("LEFT JOIN lot AS l ON l.lot_name = pi.lot_name").
+            Where("pi.pricelist_id = ?", pricelistID).
+            Order("pi.lot_name").
+            Offset(offset).
+            Limit(batchSize).
+            Scan(&items).Error
+
+        if err != nil || len(items) == 0 {

+        }
+
+        // Conditional enrichment для warehouse данных

+            r.enrichWarehouseItems(items)  // Добавление qty, partnumbers
+        }
+

+        }
+
+        offset += batchSize
+    }
+
+    return nil
+}
+```
+
+## Ключевые паттерны
+
+### 1. Streaming (не загружать все в память)
+```go
+// ❌ НЕ ТАК:
+var allItems []Item
+db.Find(&allItems)  // Может упасть на миллионах записей
+
+// ✅ ТАК:
+for offset := 0; ; offset += batchSize {
+    var batch []Item
+    db.Offset(offset).Limit(batchSize).Find(&batch)
+    processBatch(batch)
+    if len(batch) < batchSize {
+        break
+    }
+}
+```
+
+### 2. Callback Pattern для гибкости
+```go
+// Service не знает о CSV - может использоваться для любого экспорта
+func StreamItems(callback func([]Item) error) error
+```
+
+### 3. JOIN для избежания N+1
+```go
+// ❌ N+1 problem:
+items := getItems()
+for _, item := range items {
+    description := getLotDescription(item.LotName)  // N запросов
+}
+
+// ✅ JOIN:
+db.Table("items AS i").
+    Select("i.*, COALESCE(l.description, '') AS description").
+    Joins("LEFT JOIN lots AS l ON l.name = i.lot_name")
+```
+
+### 4. UTF-8 BOM для Excel
+```go
+// Excel на Windows требует BOM для корректного отображения UTF-8
+c.Writer.Write([]byte{0xEF, 0xBB, 0xBF})
+```
+
+### 5. Точка с запятой для Excel
+```go
+writer := csv.NewWriter(c.Writer)
+writer.Comma = ';'  // Excel в русской локали использует ;
+```
+
+### 6. Graceful Error Handling
+```go
+// После начала streaming нельзя вернуть JSON
+if err != nil {
+    // Уже начали писать CSV, поэтому пишем текст
+    c.String(http.StatusInternalServerError, "Export failed: %v", err)
+    return
+}
+```
+
+## Conditional Enrichment Pattern
+
+```go
+// Для warehouse прайслистов добавляем дополнительные поля
+func (r *PricelistRepository) enrichWarehouseItems(items []models.PricelistItem) error {
+    // 1. Собрать уникальные lot_names
+    lots := make([]string, 0, len(items))
+    seen := make(map[string]struct{})
+    for _, item := range items {
+        if _, ok := seen[item.LotName]; !ok {
+            lots = append(lots, item.LotName)
+            seen[item.LotName] = struct{}{}
+        }
+    }
+
+    // 2. Batch-загрузка метрик (qty, partnumbers)
+    qtyByLot, partnumbersByLot, err := warehouse.LoadLotMetrics(r.db, lots, true)
+
+    // 3. Обогащение items
+    for i := range items {
+        if qty, ok := qtyByLot[items[i].LotName]; ok {
+            items[i].AvailableQty = &qty
+        }
+        items[i].Partnumbers = partnumbersByLot[items[i].LotName]
+    }
+
+    return nil
+}
+```
+
+## Virtual Fields Pattern
+
+```go
+type PricelistItem struct {
+    // Stored fields
+    ID       uint    `gorm:"primaryKey"`
+    LotName  string  `gorm:"size:255"`
+    Price    float64 `gorm:"type:decimal(12,2)"`
+
+    // Virtual fields (populated via JOIN or programmatically)
+    LotDescription string   `gorm:"-:migration" json:"lot_description,omitempty"`
+    Category       string   `gorm:"-:migration" json:"category,omitempty"`
+    AvailableQty   *float64 `gorm:"-" json:"available_qty,omitempty"`
+    Partnumbers    []string `gorm:"-" json:"partnumbers,omitempty"`
+}
+```
+- `gorm:"-:migration"` - не создавать колонку в БД, но маппить при SELECT
+- `gorm:"-"` - полностью игнорировать при БД операциях
+
+## Checklist для CSV Export
+
+- [ ] HTTP заголовки: Content-Type, Content-Disposition
+- [ ] UTF-8 BOM для Excel (0xEF, 0xBB, 0xBF)
+- [ ] Разделитель (`;` для русской локали Excel)
+- [ ] Streaming с batch processing (не загружать всё в память)
+- [ ] JOIN для избежания N+1 запросов
+- [ ] Flush после каждого batch
+- [ ] Graceful error handling (нельзя JSON после начала streaming)
+- [ ] Динамические заголовки (если нужно)
+- [ ] Conditional enrichment (если данные зависят от типа)
+
+## Когда использовать этот паттерн
+
+✅ **Используй когда:**
+- Экспорт больших датасетов (>1000 записей)
+- Нужна Excel-совместимость
+- Связанные данные из нескольких таблиц
+- Conditional логика enrichment
+
+❌ **Не нужен когда:**
+- Малые датасеты (<100 записей) - можно загрузить всё сразу
+- Экспорт JSON/XML - другие подходы
+- Нет связанных данных - можно упростить
+
+## Пример роутинга (Gin)
+
+```go
+// В файле роутера
+func SetupRoutes(router *gin.Engine, handler *PricelistHandler) {
+    api := router.Group("/api")
+    {
+        pricelists := api.Group("/pricelists")
+        {
+            pricelists.GET("/:id/export", handler.ExportCSV)
+        }
+    }
+}
+```
+
+## Импорты
+
+```go
+import (
+    "encoding/csv"
+    "fmt"
+    "strconv"
+    "strings"
+
+    "github.com/gin-gonic/gin"
+    "gorm.io/gorm"
+)
+```
+
+## Performance Notes
+
+1. **Batch Size**: 500-1000 оптимально для большинства случаев
+2. **JOIN vs N+1**: JOIN на порядки быстрее при >100 записях
+3. **Memory**: Streaming позволяет экспортировать миллионы записей с минимальной памятью
+4. **Indexes**: Убедись что есть индексы на JOIN колонках

-# 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 |

-
-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 |
