-# Backend Patterns (NestJS)
-
-## Architecture
-
-- **Thin Controller** — business logic in Service layer
-- **DTO Validation** — class-validator + class-transformer
-- **RBAC** — CASL for authorization
-- **Error Handling** — Logger + HttpException
-
-## UUID Resolution Pattern
-
-```typescript
-// Controller - accept UUID in DTO
-@Post()
-async create(@Body() dto: CreateCorrespondenceDto) {
-  // Resolve UUID to internal ID
-  const contract = await this.contractService.findOneByUuid(dto.contractUuid);
-  const contractId = contract.id; // Internal INT for DB queries
-  
-  return this.service.create(dto, contractId);
-}
-
-// Service - use internal ID for DB operations
-async create(dto: CreateCorrespondenceDto, contractId: number) {
-  // Use contractId (INT) for database queries
-  const correspondence = this.repo.create({
-    contractId,  // FK is INT
-    // ... other fields
-  });
-  return this.repo.save(correspondence);
-}
-```
-
-## API Response Pattern
-
-```typescript
-// Entity
-@Entity()
-class Contract extends UuidBaseEntity {
-  @Column({ type: 'uuid' })
-  publicId: string;
-  
-  @PrimaryKey()
-  @Exclude()
-  id: number;
-}
-
-// Response automatically includes publicId as 'id'
-// { id: "019505a1-7c3e-7000-8000-abc123def456", ... }
-```
