+# Phase 10 Plan 02: Live Remote Name Preview Summary
+
+**One-liner:** Stateless RemoteNamePreview component with empty/value states integrated into BackendSelectionStep via watch('name') and enriched with helpText.
+
+## Tasks Completed
+
+| # | Task | Commit | Status |
+|---|------|--------|--------|
+| 1 | Create RemoteNamePreview component with TDD | 3c9c5fd | Done |
+| 2 | Integrate RemoteNamePreview and helpText into BackendSelectionStep | fefab65 | Done |
+
+## What Was Built
+
+**RemoteNamePreview component** (`src/components/ui/RemoteNamePreview.tsx`):
+- Stateless functional component accepting `{ value: string }`
+- Empty/whitespace state: displays grayed `[my-remote]` placeholder with "Type a name to see how it appears in your config" guidance
+- Value state: displays `[typed-value]` in on-surface-variant color
+- Container styling: `mt-2 rounded-md bg-surface-variant px-3 py-2 text-xs font-mono`
+- Renders only div/span elements — never form controls
+
+**BackendSelectionStep integration**:
+- Added `watch` to useForm destructure
+- Added `const remoteName = watch('name')` for reactive updates
+- Added `helpText` prop to remote name TextFieldMD3: full sentence explaining rclone.conf [name] syntax
+- Added `<RemoteNamePreview value={remoteName} />` below the TextFieldMD3
+- Note: description paragraph and RemoteNamePreview import were committed as part of Plan 10-01 linter sweep (commit 4b837b1)
+
+## Tests
+
+- `RemoteNamePreview.test.tsx`: 9 tests (empty state x3, value state x3, element type constraints x3)
+- `BackendSelectionStep.test.tsx`: 2 new integration tests (empty-state placeholder, live update on type)
+- Full suite: 202 tests pass
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed getByText(/required/i) ambiguity in BackendSelectionStep.test.tsx**
+- **Found during:** Task 2
+- **Issue:** New description paragraph ("...credentials are required in the next step") caused `getByText(/required/i)` to match two elements, breaking existing "shows inline error" test
+- **Fix:** Changed to `screen.getByRole('alert').textContent.toMatch(/required/i)` for precise alert text assertion
+- **Files modified:** `src/components/wizard/BackendSelectionStep.test.tsx`
+- **Commit:** fefab65
+
+**2. [Rule 1 - Bug] Fixed getByLabelText ambiguity in RemoteConfigStep.test.tsx**
+- **Found during:** Task 2 (full suite run)
+- **Issue:** Linter-added paragraphs in RemoteConfigStep, combined with partial `{ selector: 'input' }` fix from 10-03 commits, left GCS, B2, and S3-region VALID-01 tests failing with "Found multiple elements"
+- **Fix:** Added `{ selector: 'input' }` to all remaining `getByLabelText` calls in BACK-03, BACK-04, and VALID-01 sections
+- **Files modified:** `src/components/wizard/RemoteConfigStep.test.tsx`
+- **Commit:** fefab65 (included in Task 2 commit via linter application)
