## Elements deliberately NOT touched

- **Full-size default buttons** (Save, Cancel, Delete service, Validate SSH, Run job): `size="default"` = 32px. These have large text labels and are wide. Borderline (32px height < 44px), but adding the class to every default button would be a massive diff with marginal benefit. Prioritized icon/checkbox/switch elements and `size="sm"` elements which are 24-28px.
- **Sidebar collapse toggle** (`App.tsx` `onToggle`): Desktop-only — the Sidebar renders `null` below md, so this button never appears on mobile.
- **DataTable checkboxes/pagination** (`data-table.tsx`): Desktop-only below md (tables switch to MobileCardRow). The class would be a no-op at md+.
- **Select triggers**: The shadcn Select trigger renders a full-width dropdown control; it's typically `w-full` or `w-[70px]` and at least 32px tall. Borderline; skipped to stay surgical.
- **Dashboard anchor pills**: Already have `mobile-touch-target` from Slice 2.
- **HoverEditButton**: Already has `mobile-touch-target` from Slice 1.
- **MobileCardRow cards/checkboxes**: Already have `mobile-touch-target` from Slices 1/5.

## Validation

```
npm run lint   → 0 errors, 2 pre-existing warnings (UsersPage.impl.tsx, unrelated)
npm run build  → ✓ built (tsc -b + vite)
npm run test   → 28 files / 116 tests passed
```

## Deviations from design

None. The `mobile-touch-target` utility class was applied exactly as specified in design §`mobile-touch-target`. No new components, no refactors, no new tests (purely a className addition; R6 specifies the CSS utility as the mechanism, not testable in jsdom since `@media` queries are not honored).

## skill_resolution

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

## Residual risks

- **Default-size text buttons (32px)** remain below 44px. The class was not applied to every `size="default"` button to stay surgical and within scope. If strict WCAG 2.5.5 compliance is required on ALL interactive elements (not just icon/checkbox/switch), a second pass on default buttons is needed.
- **R4.5 dirty-state outside-click confirm** (deferred from Slices 6-8) is still unaddressed — not in this slice's scope.
- **iOS Safari attachment upload** from the compose SheetForm body is untested on real hardware — deferred to Slice 10 manual pass.
