+# 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",
+      "GPU","NIC","HCA","DPU","HBA",
+      "PSU","PS","ACC","RISERS","CARD","BB"
+    ]
+  },
+  {
+    "code":          "storage",
+    "name_ru":       "СХД",
+    "display_order": 20,
+    "categories":    [
+      "DKC","CPU","MEM","PS",
+      "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"],
+    "sections":      null
+  },
+  {
+    "key":           "storage",
+    "label":         "Storage",
+    "single_select": false,
+    "categories":    ["RAID","M2","SSD","HDD","EDSFF","HHHL"],
+    "sections": [
+      { "title": "RAID Контроллеры", "categories": ["RAID"] },
+      { "title": "Диски",            "categories": ["M2","SSD","HDD","EDSFF","HHHL"] }
+    ]
+  },
+  {
+    "key":           "pci",
+    "label":         "PCI",
+    "single_select": false,
+    "categories":    ["GPU","DPU","NIC","HCA","HBA","HIC"],
+    "sections": [
+      { "title": "GPU / DPU", "categories": ["GPU","DPU"] },
+      { "title": "NIC / HCA", "categories": ["NIC","HCA"] },
+      { "title": "HBA",       "categories": ["HBA"] },
+      { "title": "HIC",       "categories": ["HIC"] }
+    ]
+  },
+  { "key": "power",       "label": "Power",       "single_select": false, "categories": ["PS","PSU"] },
+  { "key": "accessories", "label": "Accessories", "single_select": false, "categories": ["ACC","CARD"] },
+  { "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`.

+## Ключевые изменения
+
+- BOM: поддержка формата `<qty>x <description>` при импорте Nx-спецификаций;
+- BOM: приоритет cart-LOT в дропдауне, корректный qtyMismatch при lot_qty_per_pn > 1;
+- CSV экспорт: bundle (1 PN → N LOT) разворачивается в отдельные строки;
+- ценообразование: ручная цена (buy/sale) сохраняется и экспортируется в CSV;
+- ценообразование: таблица использует qty из корзины как источник истины;
+- ценообразование: правильный порядок строк (MB→CPU→MEM→…) в pricing CSV и вкладке Ценообразование при отсутствии BOM;
+

+## Что нового
+
+### Серверно-управляемые настройки конфигуратора
+
+Типы устройств, структура вкладок и фильтры категорий теперь приезжают с сервера вместо жёстко заданных JS-констант.
+
+- новая таблица `qt_settings` на стороне сервера (контракт в `bible-local/server-contract-qt-settings.md`);
+- QF синхронизирует `qt_settings` → `local_qt_settings` (SQLite) после каждой синхронизации компонентов;
+- новый endpoint `GET /api/configurator-settings` отдаёт четыре настройки: `config_types`, `tab_config`, `always_visible_tabs`, `required_categories`;
+- при недоступности сервера или отсутствии таблицы QF автоматически использует прежние захардкоженные значения — поведение не меняется.
+
+### Динамический выбор типа оборудования
+
+- модальное окно «Новая конфигурация» загружает типы устройств с сервера: названия и количество кнопок определяются в `qt_settings.config_types`;
+- добавление новых типов устройств не требует обновления QF.
+
+### Серверно-управляемая фильтрация категорий
+
+- конфигуратор фильтрует LOT-категории по списку из `qt_settings.config_types[].categories`;
+- структура вкладок обновляется из `qt_settings.tab_config` (порядок вкладок, подразделы, single-select режим);
+- бейдж на вкладке при незаполненных обязательных категориях (`qt_settings.required_categories`).
+
+### Прочее
+
+- тайтлы страниц переименованы с OFS на QFS.
+
+## Запуск на macOS
+
+Снимите карантинный атрибут через терминал: `xattr -d com.apple.quarantine /path/to/qfs-darwin-arm64`
