I'll keep the nullable field for now to avoid a larger API change (both constructors and all internal guards would need updating), but will track this as a follow-up cleanup. The null check in `getActiveTimeline()` and `getPreviousCommitInstant()` makes the optionality explicit at each use site. -- This is an automated message from the Apache Git Service.
