feat(observability): lifecycle markers + cancel-leak fix#316
Merged
Conversation
Adds diagnostic logging across KtorServiceClient and AuthenticationManager
to make stuck-reconnect / stuck-CarPlay sessions traceable from log
captures.
- stateLabel / dcsLabel for compact, grep-stable session-state tags
- Transport state-edge logs (Connected / Reconnecting / Failed / Disconnected)
- isReadyForCommands edge collector
- Explicit "no recovery taken" branch in onAppForeground for the
actually-stuck case (state != Connected, no savedInfo); happy path
stays silent so logs aren't polluted with non-events
- "Reconnect not applicable" branch in onExternalConsumerActive
- sendRequest[msgId] markers: start/sent/resumed at .d (high volume),
cancelled/transport=null at .i (rare, informational)
- AuthMgr per-branch trace via Logger.withTag("AuthMgr")
Bug fix: sendRequest now installs invokeOnCancellation to remove the
rpcEngine callback if the parent coroutine is cancelled (e.g. a caller's
withTimeoutOrNull fires). Without this, never-arriving responses leak
orphaned callbacks for the lifetime of the session.

I added a bunch of logging to track down errors over the past few days. These are the ones that I thought were worth shipping to help with issue triaging in the future, along with fixing a small leak in sendRequest.
