- run_resume falls back to a new conversation only when the transcript file is gone; other failures end at the menu with the recorded id intact. - The SessionStart hook resolves the session name under the registry lock; rename holds it across tmux rename-session and the registry move (dd_registry_locked, nestable). - dd_load_env parses KEY=value like systemd instead of sourcing the files. - devdesk-deploy: DPkg::Lock::Timeout, explicit FAILED lines on stdout and in the log; the hook answers synchronously and CI checks the HTTP status. logrotate for the deploy log. - postinst drops duplicate terminal-features entries; hooks sweep stale temp files.
