Fix storage sync and configurator category visibility

Ampere, Hopper, Blackwell now produce AMP/HOP/BWL suffixes (like ADA)
so RTX cards across generations are distinguishable: RTX6000ADA vs
RTX6000BWL. LOVELACE remains a skip token as it duplicates ADA info.

@@ -46,16 +48,55 @@ Rules:
 - 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:
-- create a new revision only when spec or price content changes;
+- 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

+## 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.

+# 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) |

+
+### 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 |

 ## Ключевые изменения
 
-- runtime автоматически нормализует `server.host` к `127.0.0.1` и переписывает некорректный локальный конфиг;
+- pricing tab переработан: закупка и продажа разделены на отдельные таблицы с ценами за 1 шт.;
+- экран прайслиста переработан под разные типы источников; удалены misleading-колонки `Поставщик` и `partnumbers`;
+- runtime и startup ужесточены: локальный клиент принудительно работает только на loopback, конфиг автоматически нормализуется;
 - добавлены действия с вариантом и унифицированы правила именования `_копия` для вариантов и конфигураций;
-- исправлен CSV-экспорт прайсинговых таблиц в конфигураторе под Excel-совместимый формат;
-- таблица проектов переработана: новая колонка даты, tooltip с деталями, отдельный автор, компактные действия и ссылка на трекер;
+- исправлен CSV-экспорт прайсинговых таблиц в конфигураторе под Excel-совместимый формат Excel-friendly;
+- таблица проектов переработана: дата последней правки, tooltip с деталями, отдельный автор, компактные действия и ссылка на трекер;
 - sync больше не подменяет `updated_at` проектов временем синхронизации;
-- добавлена одноразовая утилита `cmd/migrate_project_updated_at` для пересинхронизации `updated_at` проектов из MariaDB в локальную SQLite.
+- добавлена одноразовая утилита `cmd/migrate_project_updated_at` для пересинхронизации `updated_at` проектов из MariaDB в локальную SQLite;
+- runtime config, release notes и `bible-local/` очищены и приведены к актуальной архитектуре;
 - `scripts/release.sh` больше не затирает существующий `RELEASE_NOTES.md`.
 
+## Summary
+
+### UI и UX
+
+- вкладка ценообразования теперь разделена на отдельные таблицы закупки и продажи;
+- список проектов переработан: новая колонка даты, отдельный автор, tooltip с деталями, компактные действия, ссылка на трекер;
+- для вариантов добавлены действия переименования, переноса и копирования;
+- копии вариантов и конфигураций теперь именуются единообразно: `_копия`, `_копия2`, `_копия3`.
+
+### Прайслисты и экспорт
+
+- экран прайслиста переработан под разные типы источников;
+- из прайслистов убраны misleading-колонки `Поставщик` и `partnumbers`;
+- CSV-экспорт прайсинговых таблиц в конфигураторе приведён к Excel-совместимому формату.
+
+### Runtime и sync
+
+- локальный runtime нормализует `server.host` к `127.0.0.1` и переписывает некорректный runtime config;
+- sync перестал подменять `updated_at` проектов временем локальной синхронизации;
+- добавлена утилита `cmd/migrate_project_updated_at` для восстановления локальных дат проектов с сервера.
+
+### Документация и release tooling
+
+- `bible-local/` сокращён до актуальных архитектурных контрактов;
+- release notes и release-структура приведены к одному формату;
+- `scripts/release.sh` теперь сохраняет существующий `RELEASE_NOTES.md` и не затирает его шаблоном.
