Each kept its own hour of quiet per event, so a budget spent on a team both control planes served was announced by each. An event is now claimed in the store before it is sent (notify_sent, migration 0043; one statement, so two asking at once cannot both win), and only the claimer sends it. A store that cannot be asked sends it anyway. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
