v5.3.8
Someone using a private shared-task link can now check or uncheck the steps delegated to them, including reopening a checklist after its final step was checked. Steps the owner had already completed before sharing remain protected.
The signed-in task editor, assignment manager, and private guest page now read the same assignment progress. A fresh login and a live guest update both refresh the open checklist without replacing unsaved task text or moving the cursor.
Guest progress remains separate from the owner-authored checklist and never completes the source task. Revision checks, link revocation, account boundaries, and private-link protections remain in place.
One short email when something meaningful ships. No streaks required.
