David debugged: Investigated calendar event duplication on completion toggle
David noticed that clicking the completion circle on a calendar event duplicated it with strikethroughs on both copies, and asked agents to investigate the backend data model.
David observed the bug in the live calendar UI.
commit and push. another issue is that, on my calendar, if i click the circle on a calendar event to mark it as completed, it duplicates the calendar event and puts a strikethrough both of them. why is it duplicating it? go launch gpt 5.5xhigh agents to investigate
A parallel read-only backend investigation was launched to inspect the completion toggle logic, task/event tables, and sync/merge behavior. The hypothesis was that completing an event was either creating a new row or changing identifiers in a way that the frontend interpreted as two separate events.
