Organization link period

The Lifecycle

Transitions Explained

Staff can add an open relationship or one with both dates already known. Ending preserves the row as history. A later ending request can repeat or shorten the last day but cannot extend it.

What Cannot Happen

The routes cannot reopen, remove or edit a link's organization, purpose or notes. Inclusive legal-entity periods for one unit cannot overlap.

Concurrency and Timing

Creation serializes on the unit row and ending serializes on the link row. This prevents competing legal-entity creations from passing the same overlap check, while duplicate nonexclusive relationships remain possible on retry.
