The backend stored the MAC, but the frontend built the approved canvas node locally with properties=[] (non-zigbee) and no mac field. On save, canvas/save upserts every node field from the in-memory canvas, so the empty properties overwrote the DB MAC — the address showed after a no-save reload but vanished once saved. Now both approve paths (single + bulk) attach a MAC property row and the mac field to the node added to the canvas, mirroring the backend build_mac_property. Hidden by default, toggleable from the right panel. - new buildMacProperty util + unit tests - bulk-approve modal test asserts MAC propagation (IP device) and absence for a zigbee device ha-relevant: yes
