When provisioning CT 302 (claude-runner) at 10.10.0.148 (same IP as deleted LXC 300), SSH connections failed with "REMOTE HOST IDENTIFICATION HAS CHANGED" on both desktop and N8N LXC. Fix: `ssh-keygen -R 10.10.0.148` on each client that previously connected to the old LXC, then reconnect with `-o StrictHostKeyChecking=accept-new`. Had to clear it on desktop (known_hosts:27) and on N8N LXC (known_hosts:1).
