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

 - every sync push/pull runs a preflight check;

 - 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.

 ## Pricing contract
 
@@ -45,16 +48,64 @@ 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
+
+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.
+
 ## Vendor BOM contract
 
 Vendor BOM is stored in `vendor_spec` on the configuration row.

+# QuoteForge v1.5.4
+
+Дата релиза: 2026-03-16
+Тег: `v1.5.4`
+
+Предыдущий релиз: `v1.5.0`
+
+## Ключевые изменения
+
+- 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 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;
+- 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.
+
+## Затронутые области
+
+- `cmd/qfs/`;
+- `cmd/migrate_project_updated_at/`;
+- `internal/localdb/`;
+- `internal/services/project.go`;
+- `internal/services/sync/service.go`;
+- `internal/handlers/pricelist.go`;
+- `web/templates/pricelist_detail.html`;
+- `web/templates/index.html`;
+- `web/templates/project_detail.html`;
+- `web/templates/projects.html`;
+- `web/templates/configs.html`;
+- `bible-local/`.
+
+## Совместимость
+
+- схема данных не меняется;
+- серверные SQL-миграции не требуются;
+- для уже испорченных локальных дат проектов можно один раз запустить `go run ./cmd/migrate_project_updated_at -apply`.
