+## Configuration types
+
+Configurations have a `config_type` field: `"server"` (default) or `"storage"`.
+
+Rules:
+- `config_type` defaults to `"server"` for all existing and new configurations unless explicitly set;
+- the configurator page is shared for both types; the SW tab is always visible regardless of type;
+- storage configurations use the same vendor_spec + PN→LOT + pricing flow as server configurations;
+- storage component categories map to existing tabs: `ENC`/`DKC`/`CTL` → Base, `HIC` → PCI (HIC-карты СХД; `HBA`/`NIC` — серверные, не смешивать), `SSD`/`HDD` → Storage (используют существующие серверные LOT), `ACC` → Accessories (используют существующие серверные LOT), `SW` → SW.
+- `DKC` = контроллерная полка (модель СХД + тип дисков + кол-во слотов + кол-во контроллеров); `CTL` = контроллер (кэш + встроенные порты); `ENC` = дисковая полка без контроллера.

 ## Vendor BOM contract

 Vendor BOM is stored in `vendor_spec` on the configuration row.

 ## MariaDB

-MariaDB is the central sync database.
+MariaDB is the central sync database (`RFQ_LOG`). Final schema as of 2026-04-15.

- `qt_pricelist_sync_status`
+Runtime read:
+- `qt_categories` — pricelist categories
+- `qt_lot_metadata` — component metadata, price settings
+- `qt_pricelists` — pricelist headers (source: estimate / warehouse / competitor)
+- `qt_pricelist_items` — pricelist rows

+- `qt_pricelist_sync_status` — pricelist sync timestamps per user

 Insert-only tracking:
- `qt_vendor_partnumber_seen`
+- `qt_vendor_partnumber_seen` — vendor partnumbers encountered during sync
+
+Server-side only (not queried by client runtime):
+- `qt_component_usage_stats` — aggregated component popularity stats (written by server jobs)
+- `qt_pricing_alerts` — price anomaly alerts (models exist in Go; feature disabled in runtime)
+- `qt_schema_migrations` — server migration history (applied via `go run ./cmd/qfs -migrate`)
+- `qt_scheduler_runs` — server background job tracking (no Go code references it in this repo)
+
+### Competitor subsystem (server-side only, not used by QuoteForge Go code)
+
+- `qt_competitors` — competitor registry
+- `partnumber_log_competitors` — competitor price log (FK → qt_competitors)
+
+These tables exist in the schema and are maintained by another tool or workflow.
+QuoteForge references competitor pricelists only via `qt_pricelists` (source='competitor').
+
+### Legacy RFQ tables (pre-QuoteForge, no Go code references)
+
+- `lot` — original component registry (data preserved; superseded by `qt_lot_metadata`)
+- `lot_log` — original supplier price log
+- `supplier` — supplier registry (FK target for lot_log and machine_log)
+- `machine` — device model registry
+- `machine_log` — device price/quote log
+- `parts_log` — supplier partnumber log used by server-side import/pricing workflows, not by QuoteForge runtime
+
+These tables are retained for historical data. QuoteForge does not read or write them at runtime.

 Rules:
- QuoteForge runtime must not depend on any removed legacy BOM tables;
- stock enrichment happens during sync and is persisted into SQLite;
- normal UI requests must not query MariaDB tables directly.
+- 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.

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

Mikhail Chusavitin	aea6bf91ab	fix: abbreviate GPU architecture suffixes in article token 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. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-09 15:08:47 +03:00
Mikhail Chusavitin	d58d52c5e7	fix: include model number and ADA suffix in GPU article token RTX 6000 ADA and A6000 are distinct cards — RTX_4000_ADA_SFF now produces RTX4000ADA instead of RTX, avoiding visual ambiguity with the segment separator (10xRTX4000ADA vs 10xRTX-1x…).

Mikhail Chusavitin	7a628deb8a	feat: add СХД configuration type with storage-specific tabs and LOT catalog guide - Add config_type field ("server"\|"storage") to Configuration and LocalConfiguration - Create modal: Сервер/СХД segmented control in configs.html and project_detail.html - Configurator: ENC/DKC/CTL categories in Base tab, HIC section in PCI tab hidden for server configs - Add SW tab (categories: SW) to configurator, visible only when components present - TAB_CONFIG.pci: add HIC section for storage HIC adapters (separate from server HBA/NIC) - Migration 029: ALTER TABLE qt_configurations ADD COLUMN config_type - Fix: skip Error 1833 (Cannot change column used in FK) in GORM AutoMigrate - Operator guide: docs/storage-components-guide.md with LOT naming rules and DE4000H catalog template Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-08 18:01:23 +03:00
Mikhail Chusavitin	7f6be786a8	feat: redesign project pricing export — FOB/DDP basis, variant filename, article column - Add FOB/DDP basis to export options; DDP multiplies all prices ×1.3 - Rename export file from "pricing" to "{FOB\|DDP} {variant}" (e.g. "FOB v1") - Fix server article missing from CSV summary row (PN вендора column) - Skip per-row breakdown when neither LOT nor BOM is selected - Remove empty separator rows between configurations - Redesign export modal: split into Артикул / Цены / Базис поставки sections Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-03 17:55:26 +03:00
Mikhail Chusavitin	a360992a01	perf: enable WAL mode, batch price lookup, add DB diagnostics to schema_state - Set PRAGMA journal_mode=WAL + synchronous=NORMAL on SQLite open; eliminates read blocking during background pricelist sync writes - Replace N+1 per-lot price loop in QuoteService local fallback with GetLocalPricesForLots batch query (120 queries → 3 per price-levels call) - Add CountAllPricelistItems, CountComponents, DBFileSizeBytes to LocalDB - Report local_pricelist_count, pricelist_items_count, components_count, db_size_bytes in qt_client_schema_state for performance diagnostics Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-02 10:53:36 +03:00

Mikhail Chusavitin	7ae804d2d3	fix: prevent config creation hang on pricelist sync SyncPricelistsIfNeeded was called synchronously in Create(), blocking the HTTP response for several seconds while pricelist data was fetched. Users clicking multiple times caused 6+ duplicate configurations. - Run SyncPricelistsIfNeeded in a goroutine so Create() returns immediately - Add TryLock mutex to SyncPricelistsIfNeeded to skip concurrent calls Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-30 12:34:57 +03:00

Mikhail Chusavitin	3661e345b1	fix: pricelist selection preserved when opening configurations - Remove 'auto (latest active)' option from pricelist dropdowns; new configs pre-select the first active pricelist instead - Stop resetting stored pricelist_id to null when it is not in the active list (deactivated pricelists are shown as inactive options) - RefreshPricesNoAuth now accepts an optional pricelist_id; uses the UI-selected pricelist, then the config's stored pricelist, then latest as a last-resort fallback — no longer silently overwrites the stored pricelist on every price refresh - Same fix applied to RefreshPrices (with auth) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-24 15:24:57 +03:00
