+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+LCC (Logistic Cost Calculator) is a Spring Boot 3.5.9 backend API for calculating complex logistics costs across supply chain networks. It handles materials, packaging, transportation rates, route planning, and multi-component cost calculations including customs duties, handling, inventory, and risk assessment.
+
+**Database Support:** The application supports both **MySQL 8.0** and **MSSQL Server 2022** through a database abstraction layer (`SqlDialectProvider`), allowing deployment flexibility across different database platforms.
+

+
+## Architecture
+
+### Layered Architecture
+```
+Controllers → DTOs → Services → Transformers → Repositories → SqlDialectProvider → Database (MySQL/MSSQL)
+```
+
+### Package Structure (`de.avatic.lcc`)
+- **controller/** - REST endpoints organized by domain (calculation, configuration, bulk, users, report)
+- **service/access/** - Business logic for domain entities (PremisesService, MaterialService, NodeService, etc.)
+- **service/calculation/** - Logistics cost calculation orchestration and step services
+- **service/calculation/execution/steps/** - Individual calculation components (airfreight, handling, inventory, customs, etc.)
+- **service/bulk/** - Excel-based bulk import/export operations
+- **service/api/** - External API integrations (Azure Maps geocoding, EU taxation)
+- **service/transformer/** - Entity-to-DTO mapping
+- **repositories/** - JDBC-based data access (not JPA) with custom RowMappers
+- **database/dialect/** - Database abstraction layer (SqlDialectProvider, MySQLDialectProvider, MSSQLDialectProvider)
+- **model/db/** - Database entity classes
+- **dto/** - Data transfer objects for API contracts
+
+### Key Design Decisions
+- **JDBC over JPA**: Uses `JdbcTemplate` and `NamedParameterJdbcTemplate` for complex queries
+- **SqlDialectProvider abstraction**: Database-agnostic SQL through dialect-specific implementations (MySQL/MSSQL)
+- **Transformer layer**: Explicit DTO mapping keeps entities separate from API contracts
+- **Calculation chain**: Cost calculations broken into fine-grained services in `execution/steps/`
+- **Profile-based configuration**: Spring profiles for environment-specific database selection
+
+### Core Calculation Flow
+```
+CalculationExecutionService.launchJobCalculation()
+  → ContainerCalculationService (container type selection: FEU/TEU/HC/TRUCK)
+  → RouteSectionCostCalculationService (per-section costs)
+  → AirfreightCalculationService
+  → HandlingCostCalculationService
+  → InventoryCostCalculationService
+  → CustomCostCalculationService (tariff/duties)
+```
+
+### Authorization Model
+Role-based access control via `@PreAuthorize` annotations:
+- SUPER, CALCULATION, MATERIAL, FREIGHT, PACKAGING, BASIC
+
+## Testing
+
+### Test Architecture
+
+**Integration Test Base Class:**
+All repository integration tests extend `AbstractRepositoryIntegrationTest`, which provides:
+- `JdbcTemplate` for test data setup
+- `SqlDialectProvider` for database-agnostic SQL
+- Helper methods: `isMysql()`, `isMssql()`, `executeRawSql()`
+- Automatic TestContainers setup via `@Testcontainers`
+- Transaction isolation via `@Transactional`
+
+**TestContainers Setup:**
+```java
+@SpringBootTest(classes = {RepositoryTestConfig.class})
+@Testcontainers
+@Import(DatabaseTestConfiguration.class)
+@Transactional
+public abstract class AbstractRepositoryIntegrationTest {
+    @Autowired
+    protected JdbcTemplate jdbcTemplate;
+
+    @Autowired
+    protected SqlDialectProvider dialectProvider;
+
+    protected boolean isMysql() {
+        return getDatabaseProfile().contains("mysql");
+    }
+
+    protected void executeRawSql(String sql, Object... params) {
+        jdbcTemplate.update(sql, params);
+    }
+}
+```
+
+**DatabaseTestConfiguration:**
+- MySQL: `MySQLContainer` with `mysql:8.0` image
+- MSSQL: `MSSQLServerContainer` with `mcr.microsoft.com/mssql/server:2022-latest` image
+- Profile-based activation via `@Profile("mysql")` and `@Profile("mssql")`
+
+### Database-Agnostic Test Patterns
+
+**Pattern 1: Boolean literals in test data**
+```java
+String sql = String.format(
+    "INSERT INTO node (name, is_active) VALUES (?, %s)",
+    dialectProvider.getBooleanTrue());
+```
+
+**Pattern 2: Auto-increment ID retrieval**
+```java
+executeRawSql("INSERT INTO table (name) VALUES (?)", name);
+String selectSql = isMysql() ? "SELECT LAST_INSERT_ID()" : "SELECT CAST(@@IDENTITY AS INT)";
+return jdbcTemplate.queryForObject(selectSql, Integer.class);
+```
+
+**Pattern 3: Date functions**
+```java
+String dateFunc = isMysql() ? "NOW()" : "GETDATE()";
+String sql = String.format("INSERT INTO table (created_at) VALUES (%s)", dateFunc);
+```
+
+### Running Tests
+
+**Run all tests on MySQL:**
+```bash
+mvn test -Dspring.profiles.active=test,mysql
+```
+
+**Run all tests on MSSQL:**
+```bash
+mvn test -Dspring.profiles.active=test,mssql
+```
+
+**Run specific repository tests:**
+```bash
+mvn test -Dtest=CalculationJobRepositoryIntegrationTest -Dspring.profiles.active=test,mysql
+mvn test -Dtest=CalculationJobRepositoryIntegrationTest -Dspring.profiles.active=test,mssql
+```
+
+**Run all repository integration tests on both databases:**
+```bash
+mvn test -Dtest="*RepositoryIntegrationTest" -Dspring.profiles.active=test,mysql
+mvn test -Dtest="*RepositoryIntegrationTest" -Dspring.profiles.active=test,mssql
+```
+
+### Test Coverage
+
+**Current Status (as of Phase 6 completion):**
+- **365 tests** passing on both MySQL and MSSQL (100% success rate)
+- **28 repository integration test classes** covering:
+  - Calculation repositories (CalculationJobRepository, CalculationJobDestinationRepository, CalculationJobRouteSectionRepository)
+  - Configuration repositories (NodeRepository, MaterialRepository, PackagingRepository, CountryRepository)
+  - Rate repositories (ContainerRateRepository, MatrixRateRepository)
+  - Property repositories (PropertyRepository, CountryPropertyRepository, PackagingPropertiesRepository)
+  - User repositories (UserRepository, GroupRepository)
+  - Bulk operation repositories (BulkOperationRepository)
+  - And 14 additional repositories
+
+**Test Data:**
+- `@Sql` annotations for controller integration tests from `src/test/resources/master_data/`
+- Repository tests use inline SQL with `executeRawSql()` for database-agnostic test data setup
+- Test data cleanup in `@BeforeEach` respects foreign key constraints
+
+## Database
+
+### Multi-Database Support
+
+The application supports both **MySQL 8.0** and **MSSQL Server 2022** through the `SqlDialectProvider` abstraction layer.
+
+**Database selection via Spring profiles:**
+- `mysql` - MySQL 8.0 (default)
+- `mssql` - Microsoft SQL Server 2022
+
+**Environment variables:**
+```bash
+export SPRING_PROFILES_ACTIVE=mysql  # or mssql
+export DB_HOST=localhost
+export DB_DATABASE=lcc
+export DB_USER=your_user
+export DB_PASSWORD=your_password
+```
+
+### SqlDialectProvider Pattern
+
+Database-specific SQL syntax is abstracted through `de.avatic.lcc.database.dialect.SqlDialectProvider`:
+
+- **MySQLDialectProvider** - MySQL-specific SQL (LIMIT/OFFSET, NOW(), ON DUPLICATE KEY UPDATE, FOR UPDATE SKIP LOCKED)
+- **MSSQLDialectProvider** - MSSQL-specific SQL (OFFSET/FETCH, GETDATE(), MERGE, WITH (UPDLOCK, READPAST))
+
+**Key dialect differences:**
+| Feature | MySQL | MSSQL |
+|---------|-------|-------|
+| Pagination | `LIMIT ? OFFSET ?` | `OFFSET ? ROWS FETCH NEXT ? ROWS ONLY` |
+| Current timestamp | `NOW()` | `GETDATE()` |
+| Date subtraction | `DATE_SUB(NOW(), INTERVAL 3 DAY)` | `DATEADD(DAY, -3, GETDATE())` |
+| Boolean literals | `TRUE`, `FALSE` | `1`, `0` |
+| Auto-increment | `AUTO_INCREMENT` | `IDENTITY(1,1)` |
+| Upsert | `ON DUPLICATE KEY UPDATE` | `MERGE` statement |
+| Insert ignore | `INSERT IGNORE` | `IF NOT EXISTS ... INSERT` |
+| Skip locked rows | `FOR UPDATE SKIP LOCKED` | `WITH (UPDLOCK, READPAST)` |
+| Last insert ID | `LAST_INSERT_ID()` | `CAST(@@IDENTITY AS INT)` |
+
+**Repository usage example:**
+```java
+@Repository
+public class ExampleRepository {
+    private final JdbcTemplate jdbcTemplate;
+    private final SqlDialectProvider dialectProvider;
+
+    public ExampleRepository(JdbcTemplate jdbcTemplate, SqlDialectProvider dialectProvider) {
+        this.jdbcTemplate = jdbcTemplate;
+        this.dialectProvider = dialectProvider;
+    }
+
+    public List<Entity> list(int limit, int offset) {
+        String sql = "SELECT * FROM table ORDER BY id " +
+                     dialectProvider.buildPaginationClause(limit, offset);
+        Object[] params = dialectProvider.getPaginationParameters(limit, offset);
+        return jdbcTemplate.query(sql, params, rowMapper);
+    }
+}
+```
+
+### Flyway Migrations
+
+Database-specific migrations are organized by database type:
+
+```
+src/main/resources/db/migration/
+├── mysql/
+│   ├── V1__Create_schema.sql
+│   ├── V2__Property_Set_Period.sql
+│   └── V3-V12 (additional migrations)
+└── mssql/
+    ├── V1__Create_schema.sql
+    ├── V2__Property_Set_Period.sql
+    └── V3-V12 (MSSQL-specific conversions)
+```
+
+**Migration naming:** `V{N}__{Description}.sql`
+
+**Key schema differences:**
+- MySQL uses `AUTO_INCREMENT`, MSSQL uses `IDENTITY(1,1)`
+- MySQL supports `TIMESTAMP ... ON UPDATE CURRENT_TIMESTAMP`, MSSQL requires triggers
+- MySQL `BOOLEAN` maps to MSSQL `BIT`
+- Check constraints syntax differs (BETWEEN vs >= AND <=)
+
+### Key Tables
+
+Core entities:
+- **premiss**, **premiss_sink**, **premiss_route** - Supply chain scenarios and routing
+- **calculation_job**, **calculation_job_destination**, **calculation_job_route_section** - Calculation workflow
+- **node** - Suppliers, destinations, intermediate locations
+- **material**, **packaging** - Product and packaging master data
+- **container_rate**, **country_matrix_rate** - Transportation rates
+- **property_set**, **property** - Versioned configuration properties
+
+## Important Database Considerations
+
+### Concurrency Control
+
+**Calculation Job Locking:**
+The `CalculationJobRepository.fetchAndLockNextJob()` method uses database-specific row-level locking to prevent concurrent job processing:
+
+- **MySQL**: `FOR UPDATE SKIP LOCKED` - Skips locked rows and returns next available job
+- **MSSQL**: `WITH (UPDLOCK, READPAST)` - Similar semantics but different syntax
+
+Both implementations ensure that multiple job processors can run concurrently without conflicts.
+
+### Transaction Isolation
+
+- Default isolation level: READ_COMMITTED
+- Repository tests use `@Transactional` for automatic rollback
+- Critical operations (job locking, rate updates) use pessimistic locking
+
+### Schema Conversion Gotchas
+
+When adding new Flyway migrations, be aware of these differences:
+
+**Auto-increment columns:**
+```sql
+-- MySQL
+id INT AUTO_INCREMENT PRIMARY KEY
+
+-- MSSQL
+id INT IDENTITY(1,1) PRIMARY KEY
+```
+
+**Timestamp with auto-update:**
+```sql
+-- MySQL
+updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
+
+-- MSSQL (requires trigger)
+updated_at DATETIME2 DEFAULT GETDATE()
+-- Plus CREATE TRIGGER for ON UPDATE behavior
+```
+
+**Boolean values:**
+```sql
+-- MySQL
+is_active BOOLEAN DEFAULT TRUE
+
+-- MSSQL
+is_active BIT DEFAULT 1
+```
+
+**Check constraints:**
+```sql
+-- MySQL
+CHECK (latitude BETWEEN -90 AND 90)
+
+-- MSSQL
+CHECK (latitude >= -90 AND latitude <= 90)
+```
+
+### Performance Considerations
+
+- Both databases use similar execution plans for most queries
+- Indexes are defined identically in both migration sets
+- MSSQL may benefit from additional statistics maintenance for complex joins
+- Performance regression < 5% observed in comparative testing
+
+## External Integrations
+
+- **Azure AD**: OAuth2/OIDC authentication
+- **Azure Maps**: Geocoding and route distance calculations (GeoApiService, DistanceApiService)
+- **EU Taxation API**: TARIC nomenclature lookup for customs duties (EUTaxationApiService)
+
+## Configuration
+
+### Profile-Based Database Configuration
+
+The application uses Spring profiles for database selection:
+
+**application-mysql.properties:**
+```properties
+spring.profiles.active=mysql
+spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
+spring.datasource.url=jdbc:mysql://${DB_HOST:localhost}:3306/${DB_DATABASE}
+spring.datasource.username=${DB_USER}
+spring.datasource.password=${DB_PASSWORD}
+
+spring.flyway.enabled=true
+spring.flyway.locations=classpath:db/migration/mysql
+spring.flyway.baseline-on-migrate=true
+```
+
+**application-mssql.properties:**
+```properties
+spring.profiles.active=mssql
+spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
+spring.datasource.url=jdbc:sqlserver://${DB_HOST:localhost}:1433;databaseName=${DB_DATABASE};encrypt=true;trustServerCertificate=true
+spring.datasource.username=${DB_USER}
+spring.datasource.password=${DB_PASSWORD}
+
+spring.flyway.enabled=true
+spring.flyway.locations=classpath:db/migration/mssql
+spring.flyway.baseline-on-migrate=true
+```
+
+**Environment Variables:**
+```bash
+# MySQL setup
+export SPRING_PROFILES_ACTIVE=mysql
+export DB_HOST=localhost
+export DB_DATABASE=lcc
+export DB_USER=root
+export DB_PASSWORD=your_password
+
+# MSSQL setup
+export SPRING_PROFILES_ACTIVE=mssql
+export DB_HOST=localhost
+export DB_DATABASE=lcc
+export DB_USER=sa
+export DB_PASSWORD=YourStrong!Passw0rd
+```
+
+### Application Properties
+
+Key properties in `application.properties`:
+- `lcc.auth.identify.by` - User identification method (workday)
+- `calculation.job.processor.*` - Async calculation job settings
+- Flyway enabled by default; migrations run on startup
+
+**Database-specific bean activation:**
+- `@Profile("mysql")` - Activates MySQLDialectProvider
+- `@Profile("mssql")` - Activates MSSQLDialectProvider
+
+## Quick Reference
+
+### Switching Databases
+
+**Switch from MySQL to MSSQL:**
+```bash
+# Update environment
+export SPRING_PROFILES_ACTIVE=mssql
+export DB_HOST=localhost
+export DB_DATABASE=lcc
+export DB_USER=sa
+export DB_PASSWORD=YourStrong!Passw0rd
+
+# Run application
+mvn spring-boot:run
+```
+
+**Switch back to MySQL:**
+```bash
+export SPRING_PROFILES_ACTIVE=mysql
+export DB_HOST=localhost
+export DB_DATABASE=lcc
+export DB_USER=root
+export DB_PASSWORD=your_password
+
+mvn spring-boot:run
+```
+
+### Running Migrations
+
+Migrations run automatically on application startup when Flyway is enabled.
+
+**Manual migration with Flyway CLI:**
+```bash
+# MySQL
+flyway -url=jdbc:mysql://localhost:3306/lcc -user=root -password=pass -locations=filesystem:src/main/resources/db/migration/mysql migrate
+
+# MSSQL
+flyway -url=jdbc:sqlserver://localhost:1433;databaseName=lcc -user=sa -password=pass -locations=filesystem:src/main/resources/db/migration/mssql migrate
+```
+
+### Testing Checklist
+
+When modifying repositories or adding new database-dependent code:
+
+1. **Run unit tests** (if applicable)
+   ```bash
+   mvn test -Dtest=MySQLDialectProviderTest
+   mvn test -Dtest=MSSQLDialectProviderTest
+   ```
+
+2. **Run repository integration tests on MySQL**
+   ```bash
+   mvn test -Dtest="*RepositoryIntegrationTest" -Dspring.profiles.active=test,mysql
+   ```
+
+3. **Run repository integration tests on MSSQL**
+   ```bash
+   mvn test -Dtest="*RepositoryIntegrationTest" -Dspring.profiles.active=test,mssql
+   ```
+
+4. **Run full test suite on both databases**
+   ```bash
+   mvn test -Dspring.profiles.active=test,mysql
+   mvn test -Dspring.profiles.active=test,mssql
+   ```
+
+### Common Repository Patterns
+
+**Pattern 1: Constructor injection with SqlDialectProvider**
+```java
+@Repository
+public class ExampleRepository {
+    private final JdbcTemplate jdbcTemplate;
+    private final SqlDialectProvider dialectProvider;
+
+    public ExampleRepository(JdbcTemplate jdbcTemplate, SqlDialectProvider dialectProvider) {
+        this.jdbcTemplate = jdbcTemplate;
+        this.dialectProvider = dialectProvider;
+    }
+}
+```
+
+**Pattern 2: Pagination queries**
+```java
+public List<Entity> list(int limit, int offset) {
+    String sql = "SELECT * FROM table WHERE condition ORDER BY id " +
+                 dialectProvider.buildPaginationClause(limit, offset);
+    Object[] params = ArrayUtils.addAll(
+        new Object[]{conditionValue},
+        dialectProvider.getPaginationParameters(limit, offset)
+    );
+    return jdbcTemplate.query(sql, params, rowMapper);
+}
+```
+
+**Pattern 3: Insert with ID retrieval**
+```java
+public Integer create(Entity entity) {
+    String sql = "INSERT INTO table (name, is_active) VALUES (?, ?)";
+    jdbcTemplate.update(sql, entity.getName(), entity.isActive());
+
+    String idSql = dialectProvider.getLastInsertIdQuery();
+    return jdbcTemplate.queryForObject(idSql, Integer.class);
+}
+```
+
+**Pattern 4: Upsert operations**
+```java
+public void upsert(Entity entity) {
+    String sql = dialectProvider.buildUpsertStatement(
+        "table_name",
+        List.of("unique_col1", "unique_col2"),          // unique columns
+        List.of("unique_col1", "unique_col2", "value"), // insert columns
+        List.of("value")                                // update columns
+    );
+    jdbcTemplate.update(sql, entity.getCol1(), entity.getCol2(), entity.getValue());
+}
+```
