Compatibility Checker Analysis

Verify backward compatibility for public APIs, exported interfaces, and external contracts.

Analysis Checklist

Public API Compatibility

• Check function signatures for parameter changes (order, type, count)
• Verify return type consistency across versions
• Detect removed or renamed public methods and properties
• Validate default value changes that alter existing behavior

Interface Contracts

• Verify exported types and interfaces remain compatible
• Check protocol/trait implementations for missing methods
• Validate serialization format compatibility (JSON, protobuf, etc.)
• Ensure event schemas and message formats are backward compatible
