Attendance Status Lifecycle - User Profile

Attendance Status Lifecycle

The attendanceStatus field tracks user progression through the event lifecycle. Any status can transition to any other status — there are no enforced transition restrictions.

created --> registered --> confirmed --> attended --> participated --> participatedPostEvent
                |              |
                v              v
           unregistered     blocked

invited --> invitedPendingRegistration --> registered --> ...

Automatic Side Effects

Every attendanceStatus change triggers:

1. previousAttendanceStatus is set to the old status value
2. statusUpdateTime is set to the current timestamp

The statuses attended, participated, and participatedPostEvent are considered "high attendance" — when a profile first transitions to any of these, firstAttendedStatusTime is automatically recorded. This timestamp is set only once and never overwritten, even if the status later changes.
