- Use nohup and disown to prevent tunnel process from being killed when step shell exits - Add logging to /tmp/ssm_tunnel.log for debugging tunnel failures - Add keepalive process that pings pg_isready every 10 seconds to prevent idle timeout - Add proactive tunnel verification (process running, port listening) before database connection This fix addresses the issue where SSM tunnels would establish successfully but die within seconds when the shell step exits, causing subsequent steps to fail.

@christabone we approved the PR but there is a 401 error on claude code review. Maybe you need to update the secret for cc in the repo? Thanks |

This run fails on purpose with claude code. Should work for any future branches going forward. |
