SatisfiesWrapperTests.swift - Tests for the @Satisfies property wrapper (10 tests) 2. DecidesWrapperTests.swift - Tests for the @Decides property wrapper (9 tests) 3. MaybeWrapperTests.swift - Tests for the @Maybe property wrapper (5 tests) 4. AsyncSatisfiesWrapperTests.swift - Tests for async specification evaluation (2 tests) Moved to SpecificationCore/Tests/SpecificationCoreTests/SpecTests/: 5.

DateComparisonSpecTests.swift - Tests for date comparison specs (1 test) 8. DateRangeSpecTests.swift - Tests for date range specs (1 test) 9. AnySpecificationPerformanceTests.swift - Performance tests for type-erased wrappers (11 tests) Test Results: - SpecificationCore: All 65 tests passing ✓ - SpecificationKit: All 514 tests passing ✓ - All imports updated from @testable import SpecificationKit to @testable import SpecificationCore - Old test files removed from SpecificationKit The core functionality tests now properly reside in the SpecificationCore module, while SpecificationKit retains tests for its extended features (macros, observed wrappers, platform providers, etc.). --- .../AnySpecificationPerformanceTests.swift | 205
