Learning: The closure `detachImpl` in `RoomLifecycleManagerTests.swift` functions as intended without external state variables to track invocation count.

221-222: LGTM: Well-documented property addition.
The hasBeenAttached property is appropriately documented with a clear reference to the specification (CHA-RL1f).
241-242: LGTM: Proper initialization of new property.
The hasBeenAttached property is correctly initialized to false, which is the appropriate default state for new contributors.
Line range hint 381-392: LGTM: Correctly implements CHA-RL4b1 specification.
The implementation properly handles the "previously attached" case by checking both the resumed flag and hasBeenAttached state before recording a pending discontinuity event. This aligns with the PR objectives and fixes the potential crash during integration tests.
656-656: LGTM: Proper state update after successful attach.
The hasBeenAttached flag is correctly set to true after a successful attach operation, ensuring accurate state tracking.
Line range hint 381-392: Verify implementation matches specification requirements.
The implementation appears to correctly address the requirements, but let's verify the behavior matches the specification exactly.
Also applies to: 656-656
✅ Verification successful
Implementation correctly handles CHA-RL4b1 specification requirements
The implementation correctly handles the CHA-RL4b1 specification requirements by:
- Checking for non-resumed ATTACHED state changes during operations
- Verifying previous attachment state via
hasBeenAttachedflag - Recording discontinuity events when appropriate
- Properly handling error cases with precondition checks
The code follows the specification exactly and includes appropriate logging for debugging purposes. No issues were found in the implementation.

Based on [1] at d9af7bf. I’m assuming that the “no call” in this spec point is a typo and means “a call”; have asked in [2]. Needed for when we integrate the room lifecycle manager into the rest of the SDK in #47 (else there will be a crash when running the integration tests, because a channel’s first ATTACHED status change has resumed == false and our precondition will fail).
