What
Claude Code keeps an internal log of a session's events. When it copies a session transcript, it first catches up on events it has not processed yet. It now wakes that catch-up step before waiting on it, and reading events for catch-up goes through a separate path made for it.
Why
In practice, the catch-up step no longer sits idle while a transcript copy waits for it.
