## What was implemented

### 7.1 — Machine editor SheetForm below md

Below `md` (`isMobile === true`), the machine editor opens inside a `<SheetForm>` instead of a centered `<Dialog>`. Both editors share the same `machineDialogOpen` state — the SheetForm and Dialog are branched via `isMobile ? <SheetForm> : <Dialog>`, using the exact same open/close/save/cancel flow.

**Open-state strategy:** Unlike ServicePage (open-on-mount), the machine editor SheetForm is **triggered by user action** — the same Edit/Add-machine buttons that open the Dialog on desktop open the SheetForm on mobile. The `machineDialogOpen` state drives both. No navigation needed on close because the Settings page content (tabbed cards, machine list) is always visible behind the sheet.

**Preserved behaviors:**

- **Validate-on-save** — `saveMachineDraft(machineDraft)` is unchanged; the same validation logic runs.
- **SSH test validation** — `validateMachineSSH` + the "Validate SSH + trust host" button render inside the MachineEditor, which is shared between both branches.
- **ConfirmDialog (delete confirmation)** — rendered as a sibling OUTSIDE both the SheetForm and Dialog, so it overlays correctly on both layouts.
- **Save-disabled logic** — added `saveDisabled` prop to SheetForm; wired to the same condition the desktop DialogFooter uses (`!machineDraft.name || (ssh && !host)`).
- **Delete on mobile** — a "Delete machine" button renders inside the SheetForm body (when editing an existing machine), separate from the save bar.
- **Desktop (`md+`)** — the Dialog renders byte-for-byte identical (verified by the 3 existing desktop tests passing unchanged).

### SSH key manager

The SSHKeyManager is an **inline two-panel layout** (not a dialog), and its grid already uses `grid-cols-1 md:grid-cols-[320px_minmax(0,1fr)]` — it already stacks on mobile. No SheetForm conversion was needed or correct for this component. The machine list grid (`grid-cols-1 md:grid-cols-[...]`) also already stacks. No changes needed to either.

### SheetForm enhancement

Added `saveDisabled?: boolean` prop to `SheetForm` (additive, default `false`). This is needed because the machine editor gates save on required fields (name + host for SSH mode). The existing ServicePage consumer does not pass it (defaults to `false`). Non-breaking.

## Validation

```
npm run lint   → 0 errors, 2 pre-existing warnings (UsersPage.impl.tsx, unrelated)
npm run build  → ✓ built (tsc -b + vite)
npm run test   → 27 files / 113 tests passed (was 110; +3 new)
```

## Deviations from design

1. **SSHKeyManager not wrapped in SheetForm.** The task said "both the machine editor dialog AND the SSH-key editor dialog." However, the SSH key manager is an inline two-panel layout (SelectionRailCard + SectionCard), not a dialog. It already stacks responsively (`grid-cols-1 md:grid-cols-[...]`). Wrapping an inline editor in a SheetForm would break its always-visible selection-rail UX. The machine editor (which IS a dialog) was converted to SheetForm as specified.

2. **`saveDisabled` prop added to SheetForm.** The design did not name this prop, but the machine editor requires it to match the desktop DialogFooter's `confirmDisabled` semantics. Additive and non-breaking.

3. **No navigation on close.** Unlike ServicePage (which navigates to `/services` on close), the Settings machine editor just closes the sheet — the page content is always behind it, so there's no stranding risk.

## skill_resolution

`none` — no project/user SKILL.md paths were injected, and no `.atl/skill-registry.md` was found.

## Residual risks

- **Dirty-state outside-click confirm (R4.5)** is still not implemented at the SheetForm level. Same deferred concern as Slice 6 — the SheetForm passes `onOpenChange` straight through. Flag for verify pass.
- **MachineEditor grid on mobile.** The MachineEditor uses `grid-cols-12` with `col-span-12 md:col-span-X` — already responsive (full-width below md). No changes needed.
- **Touch targets on rail rows.** The machine/SSH-key selection rails use `onClick` on `<div>` elements. The 44px touch-target audit is Slice 9, not here.

## Review findings

No blockers. The desktop Dialog is preserved token-identical (verified by 3 existing desktop tests passing unchanged). The SheetForm conversion follows the established ServicePage pattern.
