AutoContextSpecification Removed from Satisfies +- **Decision**: Removed AutoContextSpecification initializer from property wrappers +- **Rationale**: AutoContextSpecification protocol exists but is optional in Core +- **Impact**: Manual provider injection required (acceptable for Core package) + +### 4. Property Wrapper Tests Use Manual Instantiation +- **Decision**: Test wrappers via direct instantiation, not as struct properties +- **Rationale**: Swift doesn't allow struct property wrappers to close over external values +- **Impact**: Tests are less elegant but still comprehensive + +### 5.

**Async Context Support**: Works with context providers that provide async context -/// - **Lazy Evaluation**: Only evaluates when explicitly requested via projected value -/// - **Error Handling**: Supports throwing async operations -/// - **Flexible Specs**: Works with both sync and async specifications -/// - **No Auto-Update**: Doesn't automatically refresh; requires manual evaluation -/// -/// ## Usage Examples -/// -/// ### Basic Async Evaluation -/// ```swift -/// @AsyncSatisfies(provider: networkProvider, using: RemoteFeatureFlagSpec(flagKey: "premium")) -/// var hasPremiumAccess: Bool? -/// -/// // Evaluate asynchronously when needed -/// func checkPremiumAccess() async { -/// do { -/// let hasAccess = try await $hasPremiumAccess.evaluate() -/// if hasAccess { -/// showPremiumFeatures() -/// } -/// } catch { -/// handleNetworkError(error) -/// } -/// } -/// ``` -/// -/// ### Database Query Specification -/// ```swift -/// struct DatabaseUserSpec: AsyncSpecification { -/// typealias T = DatabaseContext -/// -/// func isSatisfiedBy(_ context: DatabaseContext) async throws -> Bool { -/// let user = try await context.database.fetchUser(context.userId) -/// return user.isActive && user.hasValidSubscription -/// } -/// } -/// -/// @AsyncSatisfies(provider: databaseProvider, using: DatabaseUserSpec()) -/// var isValidUser: Bool? -/// -/// // Use in async context -/// let isValid = try await $isValidUser.evaluate() -/// ``` -/// -/// ### Network-Based Feature Flags -/// ```swift -/// struct RemoteConfigSpec: AsyncSpecification { -/// typealias T = NetworkContext -/// let featureKey: String -/// -/// func isSatisfiedBy(_ context: NetworkContext) async throws -> Bool { -/// let config = try await context.apiClient.fetchRemoteConfig() -/// return config.features[featureKey] == true -/// } -/// } -/// -/// @AsyncSatisfies( -/// provider: networkContextProvider, -/// using: RemoteConfigSpec(featureKey: "new_ui_enabled") -/// ) -/// var shouldShowNewUI: Bool? -/// -/// // Evaluate with timeout and error handling -/// func updateUIBasedOnRemoteConfig() async { -/// do { -/// let enabled = try await withTimeout(seconds: 5) { -/// try await $shouldShowNewUI.evaluate() -/// } -/// -/// if enabled { -/// switchToNewUI() -/// } -/// } catch { -/// // Fall back to local configuration or default behavior -/// useDefaultUI() -/// } -/// } -/// ``` -/// -/// ### Custom Async Predicate -/// ```swift -/// @AsyncSatisfies(provider: apiProvider, predicate: { context in -/// let userProfile = try await context.apiClient.fetchUserProfile() -/// let billingInfo = try await context.apiClient.fetchBillingInfo() -/// -/// return userProfile.isVerified && billingInfo.isGoodStanding -/// }) -/// var isEligibleUser: Bool? -/// -/// // Usage in SwiftUI with Task -/// struct ContentView: View { -/// @AsyncSatisfies(provider: apiProvider, using: EligibilitySpec()) -/// var isEligible: Bool? -/// -/// @State private var eligibilityStatus: Bool? -/// -/// var body: some View { -/// VStack { -/// if let status = eligibilityStatus { -/// Text(status ?

**No Automatic Updates**: Unlike `@Satisfies` or `@ObservedSatisfies`, this wrapper doesn't automatically update -/// - **Manual Evaluation**: Always use `$propertyName.evaluate()` to get current results -/// - **Error Propagation**: Any errors from context provider or specification are propagated to caller -/// - **Context Caching**: Context is fetched fresh on each evaluation call -/// - **Thread Safety**: Safe to call from any thread, but context provider should handle thread safety -/// -/// ## Performance Considerations -/// -/// -
