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
