+## Terminal TUI and Completion
+
+The terminal dashboard is stdlib-only and available through
+`enodia-sentinel tui` in source/wrapper installs. Python packaging metadata also
+declares `enodia-sentinel-tui = enodia_sentinel.tui:main` for pip-style script
+generation.
+
+Shell completion has no runtime dependency: operators generate scripts with
+`enodia-sentinel completion bash` or `enodia-sentinel completion zsh` and install
+them in their normal shell completion path.
