- Thread-safe tag retrieval - AgentLabels.DropIntegrityTag() - Tag removal - AgentRegistry.GetOrCreate() - Double-checked locking pattern - AgentRegistry.Get() - Registry retrieval - AgentRegistry.Register() - Explicit registration - AgentRegistry.Remove() - Agent removal - AgentRegistry.Count() - Agent counting - AgentRegistry.GetAllAgentIDs() - ID enumeration - AgentRegistry.SetDefaultLabels() - Default configuration Coverage types: ✅ Happy path test cases ✅ Edge cases (empty inputs, boundary values) ✅ Concurrent access tests (100 goroutines) ✅ Thread safety verification ✅ State management tests ✅ Default initialization tests Previous coverage: 0-20% Estimated new coverage: 85-95% Test count: 19 comprehensive test functions --- internal/difc/agent_test.go
