|--------|--------|
| **Completeness** | ✅ 31/32 tasks complete (96.9%) |

## 1. Completeness

### Tasks Status
- **Section 1 (Foundation)**: 2/2 ✅
- **Section 2 (LabelledBox Core)**: 4/4 ✅
- **Section 3 (Input Component)**: 5/5 ✅
- **Section 4 (TextArea Component)**: 5/5 ✅
- **Section 5 (Select Component)**: 7/7 ✅
- **Section 6 (DatePicker Components)**: 6/6 ✅
- **Section 7 (Documentation & Finalization)**: 2/3 ⚠️

### Remaining Task
- **7.3 Visual review of all components in both variants in Storybook**: This is a manual task requiring human review in the browser.

## 2. Correctness

### Requirement: Field variant prop ✅
All form components accept `variant` prop with `FieldVariant.Floating` or `FieldVariant.Classic` values.

| Scenario | Status | Evidence |
|----------|--------|----------|
| Default variant is floating | ✅ | Tests verify no visual change without prop |
| Explicit floating variant | ✅ | Tests confirm identical behavior |
| Classic variant | ✅ | Tests verify label above field, placeholder displayed |

### Requirement: Floating variant label behavior ✅
| Scenario | Status | Evidence |
|----------|--------|----------|
| Empty field placeholder | ✅ | LabelledBox shows label as placeholder |
| Focused field animation | ✅ | Label animates to small position |
| Filled field label | ✅ | Label stays small above value |
| Placeholder prop ignored | ✅ | Tests verify placeholder="" in floating |

### Requirement: Classic variant label behavior ✅
| Scenario | Status | Evidence |
|----------|--------|----------|
| Label above field | ✅ | Label rendered outside wrapper with `.c__input__label` etc. |
| Placeholder support | ✅ | Native placeholder passed to input |
| Static label on focus | ✅ | Tests verify no class change on interaction |
| No placeholder case | ✅ | Field empty when no placeholder prop |

### Requirement: Classic variant compact height ✅
| Scenario | Status | Evidence |
|----------|--------|----------|
| Classic height 2.75rem | ✅ | CSS `--classic-height: 2.75rem` applied |
| Floating height 3.5rem | ✅ | Unchanged from original |

### Requirement: Select placeholder in classic variant ✅
| Scenario | Status | Evidence |
|----------|--------|----------|
| Placeholder with no selection | ✅ | `.c__select__placeholder` rendered |
| Placeholder hidden after selection | ✅ | Tests verify placeholder disappears |
| No placeholder case | ✅ | Select appears empty |

### Requirement: Backward compatibility ✅
| Scenario | Status | Evidence |
|----------|--------|----------|
| Existing code unchanged | ✅ | All existing tests pass without modification |

### Additional Features Implemented
- **`hideLabel` prop**: Added to Input, TextArea, DatePicker, DateRangePicker for accessibility
- **`FieldVariant` enum**: Converted from type union to enum for better type safety

## 3. Coherence

### Design Decisions Verified

| Decision | Implementation | Status |
|----------|---------------|--------|
| Type `FieldVariant` partagé | `enum FieldVariant` in `types.ts` | ✅ |
| Label outside wrapper in classic | Each component renders label before wrapper | ✅ |
| CSS classes per component | `.c__input__label`, `.c__textarea__label`, etc. | ✅ |
| Placeholder handling per variant | `placeholder={isClassic ? props.placeholder : ""}` | ✅ |
| Design tokens | Tokens in `LabelledBox/tokens.ts` reused | ✅ |
| DateRangePicker labels | `.c__date-picker__range__labels` with both labels | ✅ |

### Architecture Compliance
The implementation follows the design document's architecture:
```
Classic mode:
Field (wrapper)
  └── label.c__input__label (OUTSIDE - new)
  └── div.c__input__wrapper--classic (bordered wrapper)
        └── Native component (input)
```

## 4. Test Coverage

| Component | Variant Tests | hideLabel Tests |
|-----------|--------------|-----------------|
| Input | ✅ 4 tests | ✅ 2 tests |
| TextArea | ✅ 4 tests | ✅ 2 tests |
| Select (mono) | ✅ 5 tests | N/A (already had) |
| Select (multi) | ✅ 5 tests | N/A (already had) |
| DatePicker | ✅ 3 tests | ✅ 2 tests |
| DateRangePicker | ✅ 3 tests | ✅ 2 tests |
| LabelledBox | ✅ 3 tests | N/A |

**Total: 414 tests passing**

## 5. Stories Coverage

All components have Storybook stories for:
- Classic variant basic usage
- Classic variant with placeholder
- hideLabel in floating variant
- hideLabel in classic variant

## Conclusion

The implementation is **ready for final review**. All requirements from the spec are correctly implemented, design decisions were followed, and the codebase maintains backward compatibility.

The only remaining item (7.3) is a manual visual review in Storybook, which requires human verification in the browser.

### Recommended Next Steps
1. Run `yarn dev` and visually verify all components in Storybook
2. Check both variants (floating/classic) render correctly
3. Verify hideLabel works as expected (visually hidden but accessible)
4. Archive the change after visual review passes
