Update CLAUDE.md with new architecture, remove Docker

- Add development phases (pricelists, projects, local SQLite, price versioning)
- Add new table schemas (qt_pricelists, qt_projects, qt_specifications)
- Add local SQLite database structure for offline work
- Remove Docker files (distributing as binary only)
- Disable RBAC for initial phases

 ## Project Overview
 
-QuoteForge — корпоративный инструмент для конфигурирования серверов и формирования коммерческих предложений (КП). Приложение интегрируется с существующей базой данных RFQ_LOG.
+QuoteForge — корпоративный инструмент для конфигурирования серверов и формирования коммерческих предложений (КП). Приложение работает с серверной базой данных MariaDB (RFQ_LOG) и локальной SQLite для оффлайн-работы.
+
+## Development Phases
+
+### Phase 1: Pricelists in MariaDB
+- Настройка подключения к БД при первом запуске
+- Таблицы qt_pricelists и qt_pricelist_items
+- CRUD операции для прайслистов (при наличии прав записи)
+
+### Phase 2: Projects and Specifications
+- Таблицы qt_projects и qt_specifications
+- Замена qt_configurations на новую структуру
+- Поля: opty, customer_requirement, variant, qty, rev
+
+### Phase 3: Local SQLite Database
+- Локальное хранение настроек подключения
+- Кэширование прайслистов
+- Локальные проекты и спецификации
+- Синхронизация с сервером
+
+### Phase 4: Price Versioning
+- Привязка спецификаций к версиям прайслистов
+- Актуализация прайслистов с показом разницы цен
+- Автоочистка старых прайслистов (>1 года, usage_count=0)
 
 ## Tech Stack
 
 - **Language:** Go 1.22+
 - **Web Framework:** Gin (github.com/gin-gonic/gin)
 - **ORM:** GORM (gorm.io/gorm)
-- **Database:** MariaDB 11 (existing database RFQ_LOG)
+- **Server Database:** MariaDB 11 (existing database RFQ_LOG)
+- **Local Database:** SQLite (github.com/glebarez/sqlite for pure Go)
 - **Frontend:** HTML templates + htmx + Tailwind CSS (CDN)
 - **Excel Export:** excelize (github.com/xuri/excelize/v2)
-- **Auth:** JWT (github.com/golang-jwt/jwt/v5)

 ## Key Business Logic
 
-### 1. Part Number Parsing
+### 1. Database Connection Setup
+
+```go
+// First launch: show setup form
+// User provides: host, port, database, username, password
+// Credentials are encrypted and stored in SQLite
+// Connection is tested before saving
+
+func SetupConnection(host, port, dbName, user, password string) error {
+    // Test connection to MariaDB
+    // If successful, encrypt and save to SQLite
+    // Create/migrate qt_* tables if user has permissions
+}
+
+func CheckWritePermission(db *gorm.DB, tableName string) bool {
+    // Check if current user can INSERT into table
+    // Used to enable/disable pricelist creation UI
+}
+```
+
+### 2. Pricelist Creation
+
+```go
+// Create snapshot of current prices from qt_lot_metadata
+// Version format: YYYY-MM-DD-NNN (NNN = sequential number for the day)
+
+func CreatePricelist(name string, createdBy string) (*Pricelist, error) {
+    version := generateVersion() // e.g., "2024-01-31-001"
+    expiresAt := time.Now().AddDate(1, 0, 0) // +1 year
+
+    // Copy all prices from qt_lot_metadata
+    // Insert into qt_pricelists and qt_pricelist_items
+}
+
+func generateVersion() string {
+    today := time.Now().Format("2006-01-02")
+    // Count existing pricelists for today
+    // Return "YYYY-MM-DD-NNN"
+}
+```
+
+### 3. Pricelist Comparison
+
+```go
+type PriceDiff struct {
+    LotName      string
+    OldPrice     float64
+    NewPrice     float64
+    Difference   float64
+    PercentDiff  float64
+}
+
+// Compare two pricelists and return differences
+func ComparePricelists(oldID, newID int) ([]PriceDiff, error)
+
+// Compare specification's pricelist with latest available
+func GetSpecificationPriceDiff(specUUID string) ([]PriceDiff, float64, error) {
+    // Returns item diffs and total price difference
+}
+```
+
+### 4. Specification Upgrade
+
+```go
+// Upgrade specification to use newer pricelist
+func UpgradeSpecificationPricelist(specUUID string, newPricelistID int) error {
+    // Update pricelist_id
+    // Recalculate prices from new pricelist
+    // Increment revision number
+    // Update old pricelist usage_count--
+    // Update new pricelist usage_count++
+}
+```
+
+### 5. Pricelist Cleanup
+
+```go
+// Cron job: cleanup old unused pricelists
+// Run weekly: 0 4 * * 0
+func CleanupOldPricelists() error {
+    // Delete pricelists where:
+    // - expires_at < NOW()
+    // - usage_count = 0
+    // - is_active = false OR created_at < NOW() - 1 year
+}
+```
+
+### 6. Sync Service
+
+```go
+// Sync pricelists from server to local SQLite
+func SyncPricelists() error {
+    // Fetch all active pricelists from MariaDB
+    // Update local_pricelists table
+    // For pricelists used by local specs, also sync items
+}
+
+// Check if sync is needed
+func NeedSync() bool {
+    // Compare last_sync timestamp with server
+    // Return true if new pricelists available
+}
+```
+
+### 7. Part Number Parsing

-```go
-// Sort score = popularity_score * 10 + freshness_bonus - no_price_penalty
-// freshness_bonus: fresh=100, normal=50, stale=10, critical=0
-// no_price_penalty: -1000 if current_price is NULL or 0
-```
-
-### 5. Alert Generation
-
-Generate alerts when:
-- **high_demand_stale_price** (CRITICAL): >= 5 quotes/month AND price > 60 days old
-- **trending_no_price** (HIGH): trend_percent > 50% AND no price set
-- **no_recent_quotes** (MEDIUM): popular component, no supplier quotes > 90 days

 ## Cron Jobs
 
-QuoteForge now includes automated cron jobs for maintenance tasks. These can be run using the built-in cron functionality in the Docker container.
+- **Pricelist cleanup**: Weekly on Sunday at 4 AM (0 4 * * 0)
-
-### Docker Compose Setup
-
-The Docker setup includes a dedicated cron service that runs the following jobs:
-
-- **Alerts check**: Every hour (0 * * * *)
 - **Price updates**: Daily at 2 AM (0 2 * * *)
-- **Usage counter reset**: Weekly on Sunday at 1 AM (0 1 * * 0)
 - **Popularity score updates**: Daily at 3 AM (0 3 * * *)
 
-### Manual Cron Job Execution
-
-You can also run cron jobs manually using the quoteforge-cron binary:
-
-```bash
-# Check and generate alerts
-go run ./cmd/cron -job=alerts
-
-# Recalculate all prices
-go run ./cmd/cron -job=update-prices
-
-# Reset usage counters
-go run ./cmd/cron -job=reset-counters
-
-# Update popularity scores
-go run ./cmd/cron -job=update-popularity
-```
-
-### Cron Job Details
-
-- **Alerts check**: Generates alerts for components with high demand and stale prices, trending components without prices, and components with no recent quotes
-- **Price updates**: Recalculates prices for all components using configured methods (median, weighted median, average)
-- **Usage counter reset**: Resets weekly and monthly usage counters for components
-- **Popularity score updates**: Recalculates popularity scores based on supplier quote activity
-
 ## Code Style
 
 - Use standard Go formatting (gofmt)
 - Error handling: always check errors, wrap with context
-- Logging: use structured logging (slog or zerolog)
+- Logging: use structured logging (slog)
 - Comments: in Russian or English, be consistent
 - File naming: snake_case for files, PascalCase for types
+
+## Migration Notes
+
+### From qt_configurations to qt_specifications
+
+When migrating existing data:
+1. Create a default project for orphan configurations
+2. Create initial pricelist from current qt_lot_metadata prices
+3. Convert qt_configurations to qt_specifications with default variant="Base", rev=1
+4. Link all specs to initial pricelist
+
+### RBAC Disabled
+
+During Phase 1-3, RBAC is disabled:
+- No login required
+- All users have full access
+- Write permissions determined by MariaDB user privileges
+- qt_users table exists but not used
