Create personal task from updated board card for assignee

When a board card changes, personal tasks and tracking can fall out of sync. Create a matching personal to-do and log a reference row so assignees have context and can act same day.

Overview

Board changes assigned to an individual often don't surface in personal to-do lists, causing follow-ups to be missed. This flow creates a matching personal task and logs a reference row so assignees receive context and can act the same day.
