// MARK: - The shared shape

/// The shape behind every menu row this milestone ships **before** the window that answers it.
///
/// 11-command-nexus.md's own contract runs both directions: "a command absent here doesn't exist, and
/// adding one means adding a row here first" — so once a row *is* in the Nexus, shipping the window
/// behind it is a validation-and-action change, not a menu change. `FutureCommand` below is that
/// reading, applied: the row exists now, stably titled and stably chorded — `NSUserKeyEquivalents`
/// already resolves it, so a user can remap it today — with validation pinned to `false` and the
/// action a no-op until the milestone named at the call site fills both in. That milestone's whole
/// diff then reads as "flip `.disabled`, fill the closure" rather than "add a menu item", which is
/// also why every call site below carries the codebase's `mN-` marker for a component still owed.
///
/// **The title never moves once a row ships**, disabled or not: a command wired live later must not
/// gain a second spelling on the way (04-interactions.md ▸ Configurable bindings — "toggles keep one
/// stable title, checkmark state only" — which applies to a row that has not started ticking yet
/// exactly as it does to one that has).
///
/// There was a `FutureToggleCommand` beside this — a disabled `Toggle` for a checkmark row — and it
/// went with the last of its call sites (Raw Source, `RawSourceCommand`). Every row still owed is a
/// plain command; a future checkmark row brings its scaffold back with it rather than keeping an
/// unused one warm.
struct FutureCommand: View {
    let title: String
    var key: KeyEquivalent?
    var modifiers: EventModifiers = .command

    var body: some View {
        Button(title) {
            // No-op: the milestone named at the call site wires this in.

// File ▸ Save as Template was the scaffold here and is now live, beside the command it mirrors
// (`SaveAsTemplateCommand`, in `AppCommands.swift` next to `DuplicateBoardCommand`, whose flush →
// cancellable copy → banner sequence it repeats with a different destination). The diff this file
// predicts, once more: the title did not move, the chord stayed absent, the validation and the
// action filled in — the last of them being 09's carve-out from the read-only lock, which is why it
// could not simply borrow Duplicate's predicate.
//
// File ▸ Add Attachment… (⇧⌘A) was the scaffold here and is now live, beside the focused value it
// reads (`AddAttachmentCommand`, in `CardAttachments.swift`) — the diff this file predicts: the
// title and the chord did not move, the validation and the action filled in. The attachment row's
// context menu (Open / Remove / Reveal in Finder) shipped with it, on the row view that now exists.

// MARK: - Edit ▸ Find Next / Find Previous

/// Edit ▸ Find Next / Find Previous (⌘G / ⇧⌘G) — the card window's find bar stepping,
/// "disabled in the board window — board search is a live filter, not a cursor"
/// (11-command-nexus.md).
///
// m6-card-window: joins `FindCommand` in the Edit menu once the card window's find-in-text exists
// (05-card-window.md). Both rows are unconditionally disabled here rather than reading `boardStore`
// to prove "board window" disables them: there is no card-window find session anywhere yet for
// either validation branch to check.
struct FindSteppingCommands: View {
    var body: some View {
        FutureCommand(title: "Find Next", key: "g", modifiers: .command)

}

// MARK: - View ▸ Edit Body / Raw Source / History

/// View ▸ Edit Body (⌘E) / Raw Source (⌥⌘E) / History — the card window's three view-state rows
/// (11-command-nexus.md).
///
/// **Edit Body and Raw Source are both live** (`EditBodyCommand`, `RawSourceCommand`, each beside the
/// focused value it reads): the body column's Preview/Edit toggle, and the window-level outlet whose
/// toggling-off *applies*. Each diff was the one `FutureCommand` promises — the title and the chord
/// did not move, the validation and the action filled in — and the pair also carries the clause that
/// joins them, "Edit Body disables while Raw Source is active" (05-card-window.md).
///
// m7-git: History is a plain command that focuses the sidebar's History section, and disables
// outright on mode `none` / repo-nested boards once that section exists (05-card-window.md,
// 07-sync-collab.md). It remains unconditionally disabled here — the sidebar reserves the section's
// place (`CardWindowView.historySlot`) but draws nothing, so there is still no surface to focus.
/// The comments pane's two rows join them (11-command-nexus.md lists Show Comments and Comments
/// Beside Body between Edit Body and Raw Source): both are live, both are app-wide persisted bits,
/// and both are scoped to the card window (`ShowCommentsCommand`, `CommentsBesideBodyCommand`).

// MARK: - Board ▸ Pull / Push

/// Board ▸ Pull / Push — no default chord, remote-backed boards only (11-command-nexus.md;
/// 07-sync-collab.md: "also Board-menu items").
///
// m7-git: menu-bar twins of the board popover's own Pull/Push buttons (07-sync-collab.md).
// Validation will be remote-mode plus 06's abnormal-state pause ("disabled during 06's
// abnormal-state pause ... and on an unresolvable remote" — 11-command-nexus.md). Unconditionally
// disabled here: there is no remote model, no popover twin, and no git mode to validate against yet.
