PR https://git.cafe/pingdotgg/t3code/pulls/21961 PR head f04dc94b69a16511b1cd26df66f25fd428bb4c35 Baseline github/main 5808469018 (separate /home/user/main worktree) Runtime Node 24.22.1, Linux; NODE_USE_ENV_PROXY and NODE_OPTIONS unset. A real forwarding HTTP proxy listened on 127.0.0.1:18888. It forwarded CONNECT tunnels unchanged to real external hosts. No mock responses, fixtures, or demo data. For both update runs, an iptables OUTPUT rule rejected uid 1000's direct TCP port 443; the task-owned proxy ran as root and could forward. Rule removed immediately after the paired runs.
