Business Logic Implementer Implementation

Implement core business logic for new features.

Implementation Checklist

Business Rules

• Implement domain rules matching specification requirements
• Verify boundary conditions and edge case handling
• Check for proper separation of business logic from infrastructure
• Ensure business rules are unit testable in isolation
• Validate rule consistency across related operations

Validation Logic

• Implement input validation at domain boundary
• Verify validation error messages are descriptive and actionable
• Check for proper validation ordering (cheap checks first)
• Ensure cross-field and cross-entity validation rules
• Validate sanitization of user-provided data

Workflow & State Management

• Implement state transitions with proper guard conditions
• Verify invalid state transition prevention
• Check for proper event emission on state changes
• Ensure workflow steps are idempotent where required
• Validate concurrent state modification handling

Algorithm Correctness

• Verify algorithm produces correct output for all input ranges
• Check for proper handling of empty, null, and boundary inputs
• Ensure deterministic behavior for same inputs
• Validate computational complexity meets performance requirements
• Check for proper error propagation through computation chains
