# Phase 9: MD3 Components Verification Report

**Phase Goal:** Implement MD3 visual components — TextFieldMD3, StepIndicator, button styles, elevation surfaces
**Verified:** 2026-04-01T10:35:00Z
**Status:** passed
**Re-verification:** Yes — after gap closure (Plan 09-04, commit 123f24c)

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | TextFieldMD3 renders an outlined input with a floating label that floats on focus | VERIFIED | `src/components/ui/TextFieldMD3.tsx` uses `peer-focus:top-3 peer-focus:scale-75` CSS peer utilities; 9/9 unit tests pass |
| 2 | TextFieldMD3 floating label floats when the field has a value | VERIFIED | `peer-[:not(:placeholder-shown)]:top-3 peer-[:not(:placeholder-shown)]:scale-75` applied; `placeholder=" "` drives CSS detection |
| 3 | TextFieldMD3 preserves htmlFor/id pairing so getByLabelText queries work | VERIFIED | `<label htmlFor={id}>` + `<input id={id}>` pattern; Test 2 explicitly verifies `getByLabelText` |
| 4 | MD3 button class constants exist for filled, outlined, and text variants | VERIFIED | `src/styles/md3-buttons.ts` exports `MD3_BTN_FILLED`, `MD3_BTN_OUTLINED`, `MD3_BTN_TEXT` with correct `rounded-full` classes |
| 5 | FieldRenderer text-branch tooltip button uses aria-label instead of sr-only span | VERIFIED | Line 89 of FieldRenderer.tsx: `aria-label={\`More info about \${field.label}\`}` on button with plain ⓘ text; 4/4 DEBT-01 tests pass |
| 6 | Step indicator shows numbered circles for each wizard step | VERIFIED | StepIndicator.tsx lines 49-61: `w-8 h-8 rounded-full` spans with `{i + 1}` content for active/future steps |
| 7 | Completed steps display a checkmark and are clickable buttons | VERIFIED | Lines 36-45: `<button>` with `&#10003;` checkmark; test confirms selector works |
| 8 | Current step is visually highlighted with primary color | VERIFIED | Active step uses `border-primary bg-primary/10 text-primary font-bold` — no hardcoded colors |
| 9 | Future steps appear muted | VERIFIED | Future steps use `border-outline text-on-surface-container/40` semantic tokens |
| 10 | Connector lines link steps — filled for completed, muted for future | VERIFIED | `bg-primary` if `isCompleted` else `bg-outline`; `aria-hidden="true"` applied |
| 11 | Clicking step 0 dispatches SET_REMOTE_PARAMS({}) then SET_STEP(0) | VERIFIED | `handleStepClick` logic unchanged; StepIndicator tests verify params are cleared and deployment state preserved |
| 12 | All text inputs in the wizard render with floating labels | VERIFIED | FieldRenderer text-branch, PasswordField, and BackendSelectionStep "Remote name" all use TextFieldMD3. No plain `<label>+<input>` blocks remain in wizard steps. Confirmed by grep: no `<label` or `<input` outside TextFieldMD3 in BackendSelectionStep.tsx. |

**Score: 12/12 truths verified**

### Gap Closure — Truth #12

**Previously:** PARTIAL — `BackendSelectionStep.tsx` lines 58-59 contained a plain `<label htmlFor="remote-name">` + `<input id="remote-name">` block with no floating label.

**Now:** VERIFIED — Plan 09-04 (commit `123f24c`) replaced the block with:

```tsx
<TextFieldMD3
  id="remote-name"
  label="Remote name"
  registration={register('name')}
  error={errors.name}
  required
/>
```

Import confirmed at line 10: `import { TextFieldMD3 } from '../ui/TextFieldMD3';`
All 179 tests pass, zero regressions.

### Requirements Coverage

| Requirement | Source Plan(s) | Description | Status | Evidence |
|-------------|---------------|-------------|--------|----------|
| COMP-01 | 09-01, 09-03, 09-04 | All text inputs render as MD3 outlined text fields with floating labels that animate on focus and when the field has content | VERIFIED | FieldRenderer text-branch, PasswordField, and BackendSelectionStep all use TextFieldMD3. No plain label+input blocks remain in wizard step files. |
| COMP-02 | 09-03 | Buttons follow MD3 hierarchy — filled for primary actions, outlined for secondary | VERIFIED | All 4 wizard steps + OutputBlock import and apply `MD3_BTN_FILLED` / `MD3_BTN_OUTLINED` correctly |
| COMP-03 | 09-03 | Cards and output blocks use MD3 elevation with shape tokens | VERIFIED | BackendCard: `rounded-xl` + `shadow`/`shadow-md`; OutputBlock pre: `rounded-xl shadow-sm` |
| COMP-04 | 09-02 | Step indicator shows numbered circles with checkmarks, highlighted current, muted future | VERIFIED | StepIndicator rebuilt with circles, connector lines, semantic tokens, 5/5 WIZD-03 tests pass |
| DEBT-01 | 09-01 | FieldRenderer uses consistent aria-label pattern across text-branch and select-branch | VERIFIED | Both branches and PasswordField use `aria-label={\`More info about \${field.label}\`}` pattern; 4/4 tests pass |

**REQUIREMENTS.md Traceability Cross-Check:**
All 5 IDs (COMP-01, COMP-02, COMP-03, COMP-04, DEBT-01) are mapped to Phase 9 in REQUIREMENTS.md. All 5 are now marked VERIFIED with full evidence. No orphaned requirements found.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| `src/components/wizard/ReviewStep.tsx` | 16, 27 | `PLACEHOLDER` constant | Info | Legitimate empty-state UX string, not a stub — renders when config cannot be built |

No plain `<label>+<input>` blocks remain in any wizard step. No TODO/FIXME/HACK comments found in phase-09 modified files. No hardcoded hex color codes. No style={{}} props in StepIndicator.

---

### Human Verification Required

#### 1. Floating Label CSS Animation

**Test:** Navigate to BackendSelectionStep (step 1). Click into the Remote name field, then click away without typing. Then type a value, blur, then clear it.
**Expected:** On focus, the label smoothly translates upward and scales to 75%. When a value is present and the field is blurred, the label stays floated. When the value is cleared, the label returns to center. Verify the same behavior in RemoteConfigStep and PasswordField.
**Why human:** JSDOM does not compute CSS transitions or `:placeholder-shown` pseudo-class behavior. The Tailwind `peer-[:not(:placeholder-shown)]` arbitrary variant is untested by jsdom.

#### 2. MD3 Button Visual Appearance

**Test:** Navigate through all wizard steps and observe button appearances at each step.
**Expected:** Next/Download-All = pill shape with solid primary background color. Back/Copy/Download = pill shape with a visible outline border and no fill. Disabled state shows reduced opacity.
**Why human:** `MD3_BTN_*` class strings are applied correctly (verified), but the visual rendering of semantic tokens (`bg-primary`, `border-outline`, etc.) requires actual CSS custom property resolution in a browser.

#### 3. StepIndicator Visual States in Browser

**Test:** Complete step 1 (Backend selection) and observe the step indicator.
**Expected:** Step 1 circle shows a checkmark and is clickable. Step 2 circle is highlighted with a primary color border/background. Steps 3 and 4 appear muted. The connector line between steps 1 and 2 is filled (primary color); between 2-3 and 3-4 it is muted.
**Why human:** Semantic token resolution and visual differentiation of states requires browser rendering.

#### 4. Dark Mode Consistency

**Test:** Toggle to dark mode and navigate through all wizard steps.
**Expected:** All MD3 components render correctly with no hardcoded colors bleeding through. Floating label color changes on focus/error still work. Card shadows remain visible but subtle.
**Why human:** CSS custom property values under the dark theme class cannot be verified without rendering.

---

### Summary

The single gap from the initial verification is now closed. Plan 09-04 (commit `123f24c`) replaced the plain `<label>+<input>` block in `BackendSelectionStep.tsx` with `TextFieldMD3`, completing COMP-01's "All text inputs" requirement across all wizard steps.

All 12 must-have truths are VERIFIED. All 5 requirements (COMP-01, COMP-02, COMP-03, COMP-04, DEBT-01) are fully satisfied. The full test suite (179 tests across 15 files) passes with zero regressions.

Four items remain flagged for human verification — all relate to CSS animation, visual token resolution, and dark mode rendering that cannot be confirmed programmatically. These are quality-of-implementation concerns, not blockers to goal achievement.
