…delete A baremetal port on a tenant network deleted directly (skipping the update_port_postcommit bound->unbound transition) never released its dynamic VLAN segment, since _tenant_network_port_cleanup only ran on that transition. The leaked segment kept its VLAN unavailable in ml2_vlan_allocations forever, and going stale there let a later rebuild hand the same VLAN to an unrelated network.
