chat-android/src/main/java/com/ably/chat/ErrorCodes.kt (1)
87-89: Consider enhancing the error documentation.The current documentation could be more specific about which room states are considered invalid. Consider updating it to explicitly mention that this error occurs when operations are attempted while the room is not in
ATTACHEDstate, as per CHA-RL9 specification./** - * Room is not in valid state to perform any realtime operation. + * Room is not in ATTACHED state which is required for performing realtime operations, + * as specified in CHA-RL9. */chat-android/src/test/java/com/ably/chat/RoomReactionsTest.kt (1)
Line range hint
55-98: Add attachment state verification to subscription testWhile the subscription test is thorough for reaction handling, consider adding verification that:
- The subscription operation calls
ensureAttached- The subscription fails if the room is not in ATTACHED state
Example addition:
// Verify ensureAttached is called verify { room.ensureAttached() } // Test subscription failure when not attached every { room.ensureAttached() } throws InvalidRoomStateException("Room must be ATTACHED") assertThrows<InvalidRoomStateException> { roomReactions.subscribe { } }chat-android/src/test/java/com/ably/chat/Sandbox.kt (1)
31-33: LGTM! Consider adding a brief comment explaining the retry strategy.The enhanced retry condition properly handles various network timeout scenarios, making the test infrastructure more robust. Consider adding a brief comment explaining why these specific exceptions warrant retries.
retryOnExceptionIf { _, cause -> + // Retry on network timeouts to handle transient connectivity issues cause is ConnectTimeoutException || cause is HttpRequestTimeoutException || cause is SocketTimeoutException }chat-android/src/test/java/com/ably/chat/TestUtils.kt (3)
84-86: LGTM! Consider adding KDoc for better documentation.The field access utilities are well-implemented and more robust now with the ability to find fields in the class hierarchy.
Consider adding KDoc to document the behavior, especially noting that these methods can access fields from superclasses:
/** * Sets the value of a private field in this object or its superclasses. * @param name The name of the field * @param value The value to set * @throws Exception if the field is not found in the class hierarchy */ fun Any.setPrivateField(name: String, value: Any?) /** * Gets the value of a private field from this object or its superclasses. * @param name The name of the field * @return The field value cast to type T * @throws Exception if the field is not found in the class hierarchy */ fun <T>Any.getPrivateField(name: String): TAlso applies to: 90-94
96-108: Consider improving error handling and type safety.The field finding implementation is good, but there are a few potential improvements:
Consider these enhancements:
private fun Class<*>.findField(name: String): Field { var result = kotlin.runCatching { getDeclaredField(name) } var currentClass = this - while (result.isFailure && currentClass.superclass != null) // stop when we got field or reached top of class hierarchy - { + while (result.isFailure && currentClass.superclass != null) { currentClass = currentClass.superclass result = kotlin.runCatching { currentClass.getDeclaredField(name) } } if (result.isFailure) { - throw result.exceptionOrNull() as Exception + throw NoSuchFieldException("Field '$name' not found in ${this.name} or its superclasses") } - return result.getOrNull() as Field + return result.getOrNull() ?: throw IllegalStateException("Field should be present") }Changes:
- More specific exception with better error message
- Safer null handling with explicit error
- Simplified while loop formatting
Line range hint
111-116: Add error handling for method invocation edge cases.The current implementation has several potential issues that should be addressed:
Consider these improvements:
-suspend fun <T>Any.invokePrivateSuspendMethod(methodName: String, vararg args: Any?) = suspendCancellableCoroutine<T> { cont -> - val suspendMethod = javaClass.declaredMethods.find { it.name == methodName } - suspendMethod?.let { - it.isAccessible = true - it.invoke(this, *args, cont) - } +suspend fun <T>Any.invokePrivateSuspendMethod( + methodName: String, + vararg args: Any? +): T = suspendCancellableCoroutine { cont -> + val methods = javaClass.declaredMethods.filter { it.name == methodName } + when { + methods.isEmpty() -> throw NoSuchMethodException( + "No method named '$methodName' found in ${javaClass.name}" + ) + methods.size > 1 -> throw IllegalArgumentException( + "Multiple methods named '$methodName' found in ${javaClass.name}" + ) + else -> { + val method = methods.first() + if (method.parameterCount != args.size + 1) { // +1 for continuation + throw IllegalArgumentException( + "Method '$methodName' expects ${method.parameterCount - 1} arguments, but got ${args.size}" + ) + } + method.isAccessible = true + method.invoke(this, *args, cont) + } + } +}Changes:
- Added proper error handling for missing methods
- Added check for ambiguous method names
- Added parameter count validation
- Improved type safety with explicit return type
chat-android/src/test/java/com/ably/chat/PresenceTest.kt (2)
27-33: Consider improving the test setup to avoid reflection.The use of
setPrivateFieldto inject the presence mock suggests that the underlying class design might benefit from improvement. Consider:
- Making the presence field protected for testing
- Adding a constructor parameter or setter
- Using dependency injection
This would make the tests more maintainable and less brittle.
Line range hint
37-156: Add test cases for room attachment verification.Given that the PR's main objective is to "Ensure room is ATTACHED before performing operation", please add test cases to verify:
- Presence operations fail when room is not ATTACHED
- Presence operations succeed when room is ATTACHED
- Error handling for invalid room states
This will ensure the new
ensureAttachedfunctionality is properly tested.Would you like me to help generate these additional test cases?
chat-android/src/test/java/com/ably/chat/OccupancyTest.kt (1)
Line range hint
34-143: Add test cases for room state validation.The test suite needs to be extended to cover the new requirement that occupancy operations should only proceed when the room is in ATTACHED state. Consider adding the following test cases:
- Verify that occupancy operations fail when room is not ATTACHED
- Verify that operations succeed when room is ATTACHED
- Verify behavior when room state changes while operation is in progress
Here's a suggested test case structure:
@Test fun `occupancy operations should fail when room is not attached`() = runTest { // Given every { room.status } returns RoomStatus.DETACHED // When/Then assertThrows(RoomInInvalidStateException::class.java) { runBlocking { occupancy.get() } } }chat-android/src/test/java/com/ably/chat/room/RoomTestHelpers.kt (2)
40-65: LGTM! Consider adding KDoc comments.The mock creation functions are well-structured with good defaults and proper spying setup. The
recordPrivateCalls = trueensures thorough testing capabilities.Consider adding KDoc comments to document the purpose and usage of these mock creation functions, especially noting the
recordPrivateCalls = truebehavior.+/** + * Creates a mock AblyRealtime client with recorded private calls for testing. + * @return Spied instance of AblyRealtime + */ fun createMockRealtimeClient(): AblyRealtime {
76-81: LGTM! Consider grouping related properties in objects.The property accessors are well-organized and follow good naming conventions.
Consider grouping related properties into test helper objects for better organization:
object RoomLifecycleTestHelpers { internal val DefaultRoomLifecycle.InternalEmitter get() = getPrivateField<RoomStatusEventEmitter>("internalEmitter") } object EventEmitterTestHelpers { internal val EventEmitter<*, *>.Listeners get() = getPrivateField<List<Any>>("listeners") internal val EventEmitter<*, *>.Filters get() = getPrivateField<Map<Any, Any>>("filters") }chat-android/src/main/java/com/ably/chat/RoomStatus.kt (1)
Line range hint
1-224: Consider adding state validation helper method.Given the PR objective to "ensure room is ATTACHED before performing operation", consider adding a validation helper method in this file. This would centralize the state validation logic and make it reusable across the codebase.
Consider adding:
internal fun validateAttachedState() { if (status != RoomStatus.Attached) { throw ErrorInfo("Room must be in ATTACHED state to perform this operation", ErrorCode.RoomInInvalidState) } }This would provide a consistent way to implement the state validation requirement across all room operations.
chat-android/src/main/java/com/ably/chat/Occupancy.kt (1)
84-89: Consider extracting channel name suffix as a constant.The initialization changes look good, properly sourcing dependencies from the room instance. Consider extracting "::$chat::$chatMessages" as a constant since it appears to be a fixed suffix.
+ private companion object { + private const val CHANNEL_NAME_SUFFIX = "::\$chat::\$chatMessages" + } - private val messagesChannelName = "${room.roomId}::\$chat::\$chatMessages" + private val messagesChannelName = "${room.roomId}$CHANNEL_NAME_SUFFIX"chat-android/src/test/java/com/ably/chat/room/RoomEnsureAttachedTest.kt (3)
24-27: Consider enhancing the spec reference documentation.While the spec references are provided, adding brief descriptions for each spec (CHA-RL9, CHA-PR3d, etc.) would improve maintainability and make it easier for other developers to understand the test requirements without having to look up each spec separately.
56-64: Consider extracting duplicate invalid states list.The list of invalid states is duplicated in two test methods. Consider extracting it to a companion object or constant to maintain DRY principle and ensure consistency.
+ companion object { + private val INVALID_STATES = listOf( + RoomStatus.Initialized, + RoomStatus.Detaching, + RoomStatus.Detached, + RoomStatus.Suspended, + RoomStatus.Failed, + RoomStatus.Releasing, + RoomStatus.Released, + ) + }Also applies to: 135-143
71-77: Consider extracting error assertion logic.The error assertion logic is duplicated. Consider extracting it to a helper method to reduce duplication and improve maintainability.
+ private fun assertRoomInvalidStateError(result: Result<Unit>, invalidStatus: RoomStatus) { + Assert.assertTrue(result.isFailure) + val exception = result.exceptionOrNull() as AblyException + Assert.assertEquals(ErrorCode.RoomInInvalidState.code, exception.errorInfo.code) + val errMsg = "Can't perform operation, room is in an invalid state: $invalidStatus" + Assert.assertEquals(errMsg, exception.errorInfo.message) + }Also applies to: 159-164
chat-android/src/main/java/com/ably/chat/Utils.kt (2)
224-225: Add KDoc documentation for better API clarity.Consider adding KDoc documentation to explain the function's purpose, parameters, and usage examples.
+/** + * Creates an AblyException for cases when a room operation is attempted in an invalid state. + * + * @param roomStatus The current status of the room + * @return AblyException with ErrorCode.RoomInInvalidState + */ fun roomInvalidStateException(roomStatus: RoomStatus) = ablyException("Can't perform operation, room is in an invalid state: $roomStatus", ErrorCode.RoomInInvalidState)
224-225: Consider enhancing the error message with expected state information.The error message could be more helpful by including information about the expected state (ATTACHED).
fun roomInvalidStateException(roomStatus: RoomStatus) = - ablyException("Can't perform operation, room is in an invalid state: $roomStatus", ErrorCode.RoomInInvalidState) + ablyException("Can't perform operation, room must be in ATTACHED state but was: $roomStatus", ErrorCode.RoomInInvalidState)chat-android/src/main/java/com/ably/chat/Typing.kt (3)
96-96: Consider centralizing channel name constructionThe construction of
typingIndicatorsChannelNameuses a specific pattern based onroom.roomId. If similar patterns are used elsewhere, consider centralizing this construction into a utility method or constant to avoid duplication and ensure consistency across the codebase.
Line range hint
193-198: Provide a default timeout value to enhance robustnessIn
startTypingTimer(), ifroom.options.typing?.timeoutMsis null, an exception is thrown. Consider providing a reasonable default timeout value to prevent exceptions and ensure smooth user experience even if the typing options are not explicitly initialized.Example adjustment:
val timeout = room.options.typing?.timeoutMs ?: DEFAULT_TYPING_TIMEOUT_MSWhere
DEFAULT_TYPING_TIMEOUT_MSis a predefined constant, e.g.:const val DEFAULT_TYPING_TIMEOUT_MS: Long = 5000 // 5 seconds default
Line range hint
193-198: Correct grammatical error in exception messageThe exception message has a grammatical error. It should read "Typing options have not been initialized" for correct grammar.
Suggested change:
val timeout = room.options.typing?.timeoutMs ?: throw AblyException.fromErrorInfo( ErrorInfo( - "Typing options hasn't been initialized", + "Typing options have not been initialized", ErrorCode.BadRequest.code, ), )chat-android/src/main/java/com/ably/chat/Room.kt (1)
120-120: Consider keepingroomLoggerprivate for encapsulationIf

36-38: LGTM! Good practice adding default constants.
The addition of default constants improves maintainability and reduces duplication in tests.
95-106: LGTM! Verify DefaultMessages update in future PR.
The room feature mocks creation is well-structured and correctly implements the new room-based constructor pattern for all features except DefaultMessages, which will be updated in issue #68 as planned.
Let's verify that all room features (except Messages) use the room-based constructor:
✅ Verification successful
Verified: Room features follow expected constructor patterns
The verification confirms that:
DefaultMessagesuses the old constructor pattern with individual parameters (roomId, realtimeChannels, chatApi, logger)- All other room features (
DefaultTyping,DefaultRoomReactions,DefaultPresence,DefaultOccupancy) correctly use the room-based constructor pattern
This aligns with the PR's objectives and the plan to update DefaultMessages in issue #68.

182-190: LGTM! Thread-safe implementation of status properties.
The addition of @Volatile annotations ensures thread-safe access to room status and error state, which is crucial for real-time communication where state changes can occur from different threads. The initialization aligns with the CHA-RS3 specification.
Line range hint 1-224: Verify status transition patterns.
Let's verify the status transition patterns and error handling implementation across the codebase.
✅ Verification successful
Let me gather more information about the state transition validation patterns.
Let me search for more specific patterns related to state transitions and error handling.
Based on the gathered information, I can now provide a final response about the status transition patterns.
Status transition implementation is well-structured and properly validated
The implementation shows a robust state machine with:
- Clear state transition validations in RoomLifecycleManager
- Proper error handling for invalid state transitions
- Comprehensive test coverage for state transitions
- Thread-safe state management using @volatile annotations
- Consistent state validation patterns across attach/detach/release operations
Key validations found:
- Pre-condition checks before state transitions
- Proper handling of concurrent operations
- Clear error propagation with specific error codes
- Atomic state updates with proper event emission

75-76: LGTM! Constructor change aligns with PR objectives.
The simplified constructor taking only the room parameter improves encapsulation and follows the architectural changes outlined in the PR objectives.
Let's verify this pattern is consistent across other room features:
✅ Verification successful
The previous pattern was too strict. Let's try these variations to better understand the codebase structure and verify the constructor pattern consistency.
The previous patterns didn't yield results, so let's try a different approach to find similar room feature implementations and verify the constructor pattern.
Constructor pattern is consistently implemented across room features
The verification shows that the constructor pattern taking DefaultRoom parameter and extending ContributesToRoomLifecycleImpl is consistently implemented across similar room features:
- DefaultTyping
- DefaultRoomReactions
- DefaultOccupancy
- DefaultPresence
All these implementations follow the same pattern as the reviewed code, confirming that the constructor change aligns with the codebase's architectural patterns.

106-107: LGTM! Constructor refactoring improves encapsulation.
The simplified constructor taking only the room parameter aligns with the PR objectives and improves code organization by centralizing room-related functionality.
156-156: LGTM! Consistent client ID comparison.
The use of room.clientId maintains consistency with the room instance access pattern and correctly identifies self-generated reactions.
165-165: LGTM! Proper resource cleanup.
The use of room.realtimeClient maintains consistency with the room instance access pattern and ensures proper channel cleanup.
111-113: Verify channel name format compliance.
The channel name format uses a specific pattern with double colons and dollar signs. Please ensure this format aligns with the Ably specification for reaction channels.
✅ Verification successful
Channel name format is consistent across the codebase
The channel name format ${roomId}::$chat::$reactions follows a consistent pattern used throughout the codebase. This is verified by:
- The same format is used for all channel types (reactions, typing indicators, chat messages)
- Multiple test files validate this exact format
- The pattern
roomId::$chat::$<type>is consistently applied across all channel name definitions

138-139:
Critical state validation before publishing.
The addition of ensureAttached() check aligns with the requirement (CHA-RL9) to ensure room operations only proceed when the room is in ATTACHED state. However, note the TODO comment about potential future removal.
chat-android/src/test/java/com/ably/chat/room/RoomEnsureAttachedTest.kt (4)
150-150: Good use of SupervisorJob for error handling.
The use of SupervisorJob for the async operation is a good practice as it prevents error propagation to the parent coroutine scope, allowing for proper error handling in the test.
Also applies to: 151-151
1-169: Overall, the test implementation is robust and well-structured.
The test suite provides comprehensive coverage of the ensureAttached functionality, testing various room states and error conditions. The use of coroutines and mocking is appropriate, and the tests are well-organized with clear spec references.
114-117: Consider adding timeout to assertWaiter.
The assertWaiter is used to wait for a condition but doesn't seem to have a timeout. Consider adding a timeout to prevent infinite waits in case of test failures.
31-31: Verify mock creation helper functions.
The test uses createMockLogger() and createMockRealtimeClient() helper functions. Please ensure these are properly imported and available.
Also applies to: 33-33
✅ Verification successful
Helper functions are properly accessible
The mock creation helper functions createMockLogger() and createMockRealtimeClient() are defined in RoomTestHelpers.kt in the same package com.ably.chat.room as the test file. In Kotlin, functions in the same package are accessible without explicit imports, so there's no issue here.

136-137: Refactor constructor to accept 'room' parameter
The constructor now accepts a room: DefaultRoom parameter, enhancing encapsulation and simplifying object initialization by leveraging the room object for shared resources.
145-149: Initialize properties using 'room' object for improved cohesion
By initializing channel, logger, and presence using the room object, the codebase benefits from better cohesion and maintainability, reducing redundancy.
152-152: Enforce room attachment before performing presence operations
Adding room.ensureAttached() in get, enter, update, and leave methods ensures that presence operations are only performed when the room is in the ATTACHED state, adhering to the specification in issue #62.
Also applies to: 166-166, 171-171, 176-176
152-152: Verify exception handling for 'ensureAttached' method
Ensure that any exceptions thrown by room.ensureAttached() are properly propagated or handled, and that users receive meaningful error messages if operations are attempted when the room is not attached.
Run the following script to verify that exceptions from room.ensureAttached() are appropriately propagated:
Also applies to: 166-166, 171-171, 176-176
✅ Verification successful
Let me gather more information about the exception handling patterns in the codebase.
Let me check the implementation of ensureAttached() and its error handling.
Based on the gathered information, I can now provide the final response:
Exception handling for ensureAttached() is properly implemented
The ensureAttached() method has appropriate error handling:
- It throws a well-defined
AblyExceptionwithErrorCode.RoomInInvalidStatewhen the room is in an invalid state - It includes a descriptive error message: "Can't perform operation, room is in an invalid state: {status}"
- The error propagation is verified through unit tests in
RoomEnsureAttachedTest - The method properly handles the
Attachingstate by waiting for the room to becomeAttached

156-156: Ensure exceptions from room.ensureAttached() are handled appropriately
In the get() method, room.ensureAttached() may throw an exception if the room is not in the correct state. Since this is a suspend function, the exception will propagate up the call stack. Ensure that callers of this method handle potential exceptions to maintain application stability.
chat-android/src/main/java/com/ably/chat/Room.kt (3)
6-6: Imports are necessary for coroutine usage
The addition of CompletableDeferred and launch imports is appropriate for the implementation of asynchronous operations in ensureAttached().
Also applies to: 11-11
115-117: Visibility change to 'internal' is appropriate
Changing the constructor parameters from private to internal allows room features to access these properties directly from the DefaultRoom instance, which aligns with the new initialization approach for feature classes.
189-189: Simplified feature initialization improves maintainability
Updating feature constructors to accept only room = this simplifies the initialization process and enhances code readability by reducing parameter redundancy.

36-37: Consider adding room state setup.Given the PR's focus on ensuring room is ATTACHED before operations, consider explicitly setting up the room state in the test setup.
room = createMockRoom("room1", "client1", realtimeClient = realtimeClient) +// Ensure room is in ATTACHED state for tests +every { room.status } returns RoomStatus.ATTACHED roomReactions = DefaultRoomReactions(room)chat-android/src/test/java/com/ably/chat/PresenceTest.kt (1)
29-29: Consider alternatives to reflection for presence injection.Using
setPrivateFieldfor presence injection makes the tests more brittle and harder to maintain. Consider:
- Exposing presence through a protected field
- Using a test-specific constructor
- Creating a builder pattern for test instances

3-5: LGTM! Appropriate mock helper imports added.
The new imports align well with the refactoring to use centralized mock creation helpers.
19-21: LGTM! Properties simplified and aligned with new architecture.
The property changes appropriately reflect the shift to using a single channel and the new room-centric approach.
25-37: Verify the channel name pattern consistency.
The hardcoded channel name pattern room1::$chat::$reactions should be verified against any specification or constant definitions.
✅ Verification successful
Channel name pattern is correctly implemented
The hardcoded channel name pattern in the test room1::$chat::$reactions follows the established pattern used throughout the codebase. This is confirmed by:
- The production code in
RoomReactions.ktdefines it as"${room.roomId}::$chat::$reactions" - Multiple lifecycle tests consistently use the same pattern (e.g.,
"1234::$chat::$reactions") - The pattern is used consistently for reaction channel identification across attach, detach, and release operations

The new imports for mock creation utilities (createMockChannel, createMockRealtimeClient, createMockRoom) reflect a more structured approach to test setup.
21-22: LGTM: Improved variable naming and type clarity.
The rename from pubSubChannel to pubSubPresence better reflects its purpose and type, improving code readability.
27-29: Verify the channel name pattern usage across tests.
The hardcoded channel name pattern "room1::$chat::$messages" might need to be consistent with other tests or extracted to a constant.

3-5: LGTM! Good refactoring of mock creation.
The centralization of mock creation utilities through these imports helps standardize test setup across the codebase.
19-21: LGTM! Properties align with the new room-centric approach.
The property changes reflect the architectural shift to make room the central entity, which aligns with the PR objectives.
25-37: 🛠️ Refactor suggestion
Add room status setup in setUp method.
Given that this PR focuses on room state validation, consider setting up the room status explicitly in the setUp method to ensure consistent test behavior.
@Before
fun setUp() {
val realtimeClient = createMockRealtimeClient()
realtimeChannel = realtimeClient.createMockChannel("room1::$chat::$reactions")
every { realtimeClient.channels.get(any(), any()) } answers {
val channelName = firstArg<String>()
if (channelName == "room1::$chat::$reactions") {
realtimeChannel
} else {
buildRealtimeChannel(channelName)
}
}
room = createMockRoom("room1", "client1", realtimeClient = realtimeClient)
+ every { room.status } returns RoomStatus.ATTACHED
roomReactions = DefaultRoomReactions(room)
}Additionally, as mentioned in the previous review, consider adding test cases for non-ATTACHED states.
45-50: 🛠️ Refactor suggestion
Add room state validation in the channel name test.
Since the PR focuses on room state validation, consider verifying that operations only proceed when the room is in the correct state.
@Test
fun `channel name is set according to the spec`() = runTest {
+ // Given
+ every { room.status } returns RoomStatus.ATTACHED
+
+ // When
val roomReactions = DefaultRoomReactions(room)
+ // Then
assertEquals(
"room1::$chat::$reactions",
roomReactions.channel.name,
)
+
+ verify { room.status }

3-5: LGTM! Import changes align with new mock infrastructure.
The new imports for mock creation utilities improve test setup consistency.
21-33: LGTM! Test setup refactoring improves mock infrastructure.
The changes to use dedicated mock creation methods and proper field injection improve test maintainability.
33-33: Add tests for room ATTACHED state verification.
Given that the PR's main objective is ensuring room is ATTACHED before operations, the test suite should include verification of this requirement. Consider adding test cases that verify:
- Operations fail when room is not ATTACHED
- Operations succeed when room is ATTACHED
- Proper error handling for invalid room states
33-33: Verify room state validation implementation.
Let's verify the implementation of room state validation in the codebase.
✅ Verification successful
Based on the search results, I can now generate the final response. The code shows proper room state validation through the ensureAttached() method which is called by the presence implementation before any presence-related operations.
Room state validation is properly implemented.
The codebase shows:
DefaultPresencecallsroom.ensureAttached()before all presence operations (enter, update, leave, get)ensureAttached()validates that the room is either inATTACHEDstate or properly handles theATTACHINGstate- Comprehensive test coverage verifies the state validation behavior
- The implementation follows the required specifications (CHA-PR3d, CHA-PR6c, etc.)

36-38: LGTM! Good practice adding default constants.
The addition of default constants improves maintainability and reduces duplication in tests.
76-81: Verify private field names across dependent modules.
The property accessors rely on exact private field names. This could break if the field names change in the referenced classes.
95-106: LGTM! Verify feature coverage is complete.
The changes align well with the PR objective to simplify feature constructors. The implementation correctly uses the new mock creation functions and consistently records private calls.
✅ Verification successful
Let me gather more information to verify all room features by searching for implementations in a different way.
Let me search for all default implementations to ensure complete coverage.
All room features are properly covered in the mock creation
Based on the verification results, all ContributesToRoomLifecycle implementations are correctly mocked in createRoomFeatureMocks:
- DefaultMessages (with custom constructor)
- DefaultPresence
- DefaultOccupancy
- DefaultTyping
- DefaultRoomReactions
These match all the feature implementations found in the main source code that implement ContributesToRoomLifecycle.

Properties are properly initialized from the room instance, maintaining encapsulation and following the expected patterns for channel naming and logging.
145-145:
Add ensureAttached() check before performing operation.
According to the PR objectives and specification CHA-RL9, every room operation should verify that the room is in ATTACHED state before proceeding. This check is missing in the get() method.

The change to use room.clientId is consistent with the constructor refactoring and maintains the same functionality.
165-165: LGTM: Consistent use of room.realtimeClient.channels
The change to use room.realtimeClient.channels is consistent with the constructor refactoring and maintains the same functionality.
138-139: Verify ensureAttached implementation and document spec dependency
The addition of ensureAttached() check aligns with PR objectives. However, the TODO comment suggests potential future removal due to core spec changes.
✅ Verification successful
Let me gather more information about the implementation and spec references.
ensureAttached implementation is well-tested and spec-compliant
The ensureAttached() implementation is properly documented and follows multiple spec requirements (CHA-PR3d, CHA-PR10d, CHA-PR6c, CHA-RL9). The TODO comment about potential removal appears to be forward-looking but doesn't affect current functionality, as the implementation is currently required and well-tested. The method correctly handles both ATTACHED and ATTACHING states, throwing appropriate exceptions for invalid states.

The channel name uses a specific format with double colons and dollar signs. Let's verify this naming convention is consistent across the codebase.
✅ Verification successful
Let's search with a broader pattern to find channel naming conventions, as the specific pattern might have variations or the dollar signs might be handled differently in the codebase.
Channel naming convention is consistent across the codebase
The channel naming pattern {roomId}::$chat::$reactions is consistently used throughout the codebase, as evidenced by:
- Implementation in
RoomReactions.kt - Test assertions in multiple test files (
RoomReactionsTest.kt,RetryTest.kt,DetachTest.kt,ReleaseTest.kt,AttachTest.kt) - The pattern follows the same format as other chat channels (e.g.,
