A custom in-window menu bar in the hat (no native menu, D-7), built from
the command registry so it stays in sync and satisfies D-6 parity.
- Menu model + hybrid resolver (menu_model.dart): a curated File/View/Help
tree where a MenuAutoFill node sweeps in unplaced view.* commands; titles
+ keybindings come from the registry/keymap; unregistered or
enabledWhen-false items render disabled (greyed), never hidden.
- Widgets: MenuBar row in the hat (chrome tokens), anchored MenuDropdown
overlay (dropdown tokens), two-column MenuItemRow with inline keybinding.
- Full keyboard: Alt+mnemonic opens (hook in _RootShell._onKey), arrows
navigate, Enter activates, Esc closes, Left/Right switch menus.
- Commands: file.openFolder / file.newWindow / file.closeWorkspace /
help.about, registered by MenuBarExtension(services:). File logic lifted
out of the project switcher into FileActions (one source of truth; the
switcher now dispatches the commands). Ctrl+O / Ctrl+Shift+N are now real
keybindings in default.yaml.
- Help → About: version/commit/date/repo from build-info + the bundled
dependency licenses parsed from assets/licenses.yaml.
Edit/Selection menus are deferred to T-271/T-272 (need focused-surface
command routing).
Tests: resolver + controller + licenses parse (pure); menu-bar widget
(open/close/execute/disabled/Esc/arrow/Enter/Left-Right); FileActions +
Open dialog; app-level Alt+F, non-repo dialog, and closeWorkspace.
