+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Overview
+
+SundialKitStream is a modern Swift 6.1+ async/await observation plugin for SundialKit, providing actor-based observers with AsyncStream APIs for network monitoring and WatchConnectivity communication. The package prioritizes strict concurrency safety, avoiding `@unchecked Sendable` conformances in favor of proper actor isolation.
+
+## Development Commands
+
+### Building
+
+```bash
+# Build the package
+swift build
+
+# Build including tests
+swift build --build-tests
+
+# Run tests
+swift test
+```
+
+### Linting
+
+The project uses a comprehensive linting setup with SwiftLint, swift-format, and periphery (dead code detection):
+
+```bash
+# Run all linting and formatting
+./Scripts/lint.sh
+
+# Format only (skip linting checks)
+FORMAT_ONLY=1 ./Scripts/lint.sh
+
+# Strict mode (used in CI)
+LINT_MODE=STRICT ./Scripts/lint.sh
+```
+
+**Important**: Linting requires `mise` to be installed. The lint script uses mise to manage tool versions via `.mise.toml`.
+
+### Testing
+
+```bash
+# Run all tests
+swift test
+
+# Run a specific test target
+swift test --filter SundialKitStreamTests
+
+# Run a specific test class
+swift test --filter NetworkObserverTests
+
+# Run a specific test method
+swift test --filter NetworkObserverTests.testStreamUpdates
+```
+
+## Code Architecture
+
+### Layer Architecture
+
+SundialKitStream follows a three-layer architecture:
+
+1. **Core Protocols** (Dependencies from SundialKit package):
+   - `SundialKitCore` - Base protocols and types (`ActivationState`, `ConnectivityError`, etc.)
+   - `SundialKitNetwork` - Network monitoring protocols (`PathMonitor`, `NetworkPing`, `PathStatus`)
+   - `SundialKitConnectivity` - WatchConnectivity protocols (`ConnectivitySession`, `Messagable`)
+
+2. **Observer Layer** (This package - SundialKitStream):
+   - Actor-based observers: `NetworkObserver`, `ConnectivityObserver`
+   - AsyncStream-based state delivery
+   - Manages continuations and distributes updates to multiple subscribers
+
+### Core Observers
+
+#### NetworkObserver
+
+Actor-based network connectivity monitoring with AsyncStream APIs:
+
+- **Generic over**: `PathMonitor` (typically `NWPathMonitorAdapter`) and `NetworkPing`
+- **Streams**: `pathStatusStream`, `isExpensiveStream`, `isConstrainedStream`
+- **Thread Safety**: Actor isolation ensures safe concurrent access
+- **Location**: Sources/SundialKitStream/NetworkObserver.swift
+
+#### ConnectivityObserver
+
+Actor-based WatchConnectivity communication with AsyncStream APIs:
+
+- **Protocols**: Conforms to `ConnectivitySessionDelegate`, `StateHandling`, `MessageHandling`
+- **Key Components**:
+  - `ConnectivityStateManager` - Manages activation, reachability, and pairing state
+  - `StreamContinuationManager` - Centralized continuation management for all stream types
+  - `MessageDistributor` - Handles incoming message distribution to subscribers
+  - `MessageRouter` - Routes outgoing messages through appropriate transports
+- **Streams**: `activationStates()`, `activationCompletionStream()`, `reachabilityStream()`, `messageStream()`, `typedMessageStream()`
+- **Location**: Sources/SundialKitStream/ConnectivityObserver.swift
+
+### Key Architectural Patterns
+
+#### AsyncStream Continuation Management
+
+The codebase uses a centralized continuation management pattern via `StreamContinuationManager`:
+
+- Each stream type has its own continuation dictionary keyed by UUID
+- Registration asserts prevent duplicate continuations
+- Removal asserts catch programming errors
+- Yielding iterates all registered continuations for fan-out distribution
+- **Location**: Sources/SundialKitStream/StreamContinuationManager.swift
+
+#### State Management
+
+`ConnectivityStateManager` coordinates state updates with stream notifications:
+
+- Maintains `ConnectivityState` with activation, reachability, and pairing information
+- Synchronizes state updates with continuation notifications
+- Provides read-only snapshot accessors for current state
+- **Location**: Sources/SundialKitStream/ConnectivityStateManager.swift
+
+#### Message Handling
+
+Message flow uses a routing and distribution pattern:
+
+- `MessageRouter` - Selects appropriate transport (interactive message, application context, etc.)
+- `MessageDispatcher` - Transforms protocol-level callbacks into async operations
+- `MessageDistributor` - Distributes received messages to all active stream subscribers
+- Supports both untyped (`[String: any Sendable]`) and typed (`Messagable`) messages
+
+## Swift Version and Compiler Settings
+
+This package requires **Swift 6.1+** and enables extensive experimental features:
+
+- **Swift 6.2 Upcoming Features**: ExistentialAny, InternalImportsByDefault, MemberImportVisibility, FullTypedThrows
+- **Experimental Features**: BitwiseCopyable, BorrowingSwitch, NoncopyableGenerics, TransferringArgsAndResults, VariadicGenerics, and many more (see Package.swift:8-34)
+- **Strict Concurrency**: The project operates in Swift 6 strict concurrency mode
+
+When writing new code, ensure:
+- All public types properly declare their concurrency characteristics (`actor`, `@MainActor`, `Sendable`)
+- No `@unchecked Sendable` conformances are added
+- AsyncStream continuations are managed through `StreamContinuationManager`
+
+## File Organization
+
+Source files use functional organization with extensions:
+
+- Main type definition: `TypeName.swift`
+- Extensions by functionality: `TypeName+Functionality.swift`
+- Example: `ConnectivityObserver.swift`, `ConnectivityObserver+Lifecycle.swift`, `ConnectivityObserver+Messaging.swift`, `ConnectivityObserver+Streams.swift`
+
+Tests follow a similar pattern with hierarchical organization:
+
+- Test suites: `TypeName.swift`, `TypeName+Category.swift`
+- Individual test files: `TypeName.Category.SpecificTests.swift`
+- Example: `ConnectivityStateManager.swift`, `ConnectivityStateManager.State.swift`, `ConnectivityStateManager.State.UpdateTests.swift`
+
+## Code Style and Linting
+
+The project enforces strict code quality standards:
+
+- **File Length**: Warning at 225 lines, error at 300 lines
+- **Function Body Length**: Warning at 50 lines, error at 76 lines
+- **Line Length**: Warning at 108 characters, error at 200 characters
+- **Cyclomatic Complexity**: Warning at 6, error at 12
+- **Indentation**: 2 spaces (configured in .swiftlint.yml:120)
+- **Access Control**: Explicit access levels required (`explicit_acl`, `explicit_top_level_acl`)
+- **File Headers**: All source files require proper copyright headers (enforced by Scripts/header.sh)
+
+Disabled rules:
+- `nesting`, `implicit_getter`, `switch_case_alignment`, `closure_parameter_position`, `trailing_comma`, `opening_brace`, `pattern_matching_keywords`, `todo`
+
+## Dependencies
+
+This package depends on SundialKit v2.0.0+ which provides three products:
+
+- `SundialKitCore` - Core protocols and types
+- `SundialKitNetwork` - Network monitoring abstractions over Apple's Network framework
+- `SundialKitConnectivity` - WatchConnectivity abstractions
+
+## Platform Support
+
+- iOS 16+
+- watchOS 9+
+- tvOS 16+
+- macOS 13+
+
+## Testing Patterns
+
+Tests use mock implementations for protocol-based abstractions:
+
+- `MockPathMonitor` - Simulates network path changes
+- `MockNetworkPing` - Simulates ping operations
+- `MockConnectivitySession` - Simulates WatchConnectivity behavior
+- `TestValueCapture` - Captures async stream values for testing
+
+When writing tests:
+- Use actor-isolated test methods when testing actors
+- Capture stream values with async task groups or `TestValueCapture`
+- Test both success and error paths for `Result`-based streams (e.g., `activationCompletionStream()`)
+- In order to run the builds and tests for iOS or watchOS, use xcodebuild.
+- Don't use swift package generate-xcodeproj
