The bridge module gained delete_nio_tap (uBridge's gns3server-integration contract, section 'bridge — generic NIO relay with a swappable TAP leg'): a per-port bridge can swap its topology leg between UDP and a persistent TAP through stop -> delete -> add -> start, which is what lets an IOL runner container's port bridge carry a kernel-link anchor. The probe needs no scratch objects and no capabilities: one command against a bridge that cannot exist — 202 (unknown command) is an old build, 214 (bridge doesn't exist) is a new one. Cached by binary identity like every other probe; any failure reports unknown. GET /v3/compute/capabilities gains ubridge_bridge_tap; the controller's default capability dict carries it too (the single schema definition, per the 1e67fbf12 lesson).
