The tests probe a free port (bind 0, release) and start the SDK server later; under a highly parallel run another test can take the port in between and the SDK fails with 'Failed to establish tcp listener sockets for Ipv4 and IPv6.'. OpcUaHostStart.StartAsync builds a fresh host + server on a fresh port per attempt (up to 5) when the failure is a bind failure; all 45 start sites in OpcUaServer.Tests, OpcUaServer.IntegrationTests and Runtime.Tests use it. Per-attempt GUID ApplicationUris are hoisted out of the host factory because a changed URI against a reused PKI store fails with 'Cannot access private key'.
