What
While Claude is busy, messages you send wait in a queue. Claude Code saves changes to that queue in a session's transcript, the file that records the conversation. When a queue entry belongs to a different session than the current one, it is now written to that session's transcript, but only if that file already exists. These writes happen one at a time, in order.
Why
Queued messages should no longer end up recorded in the wrong session's history.
