What
When Claude Code refreshes an OAuth (login) token, it briefly locks a file to coordinate with other processes. The tengu_oauth_token_refresh_lock_acquired telemetry event that marks this used to fire right after the lock file was acquired; it now fires later, immediately before the strict read-check that follows. The internal helper that acquires the lock was also swapped for a different one.
Why
This is an internal reordering of when a telemetry event fires relative to the lock's actual use, which affects how accurately the event reflects the state of the lock at the time it's recorded.
