Deploy Ladill Hosting / deploy (push) Successful in 45s
The toolbar showed a static ~/public_html. The jailed shell now reports its cwd via OSC 7 each prompt (jail rcfile keeps the user's prompt + emits it); xterm captures it and the toolbar shows the full path (/home/<user>/...), updating as the user cd's. Launcher/rcfile committed in deployment/ for reproducibility. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
