# Navigation Hover Enhancement - Brownfield Addition
|
|
|
|
## Story Title
|
|
Navigation Hover Enhancement - Brownfield Addition
|
|
|
|
## User Story
|
|
As a **website visitor**,
|
|
I want **the navigation bar to appear when I hover over the top area of the page when at scroll position 0 on desktop**,
|
|
So that **I can access navigation options without needing to scroll down, providing better usability and seamless access to site sections**.
|
|
|
|
## Story Context
|
|
|
|
**Existing System Integration:**
|
|
- Integrates with: Navigation component (`components/navigation.tsx`)
|
|
- Technology: React, Next.js, Tailwind CSS, TypeScript
|
|
- Follows pattern: Existing scroll-based visibility logic and CSS transitions
|
|
- Touch points: Navigation state management, CSS conditional styling, scroll event handling
|
|
|
|
## Acceptance Criteria
|
|
|
|
**Functional Requirements:**
|
|
1. When at scroll position 0 (top of page) on desktop (lg+ breakpoints), hovering over the top navigation area makes the navigation bar visible
|
|
2. Navigation appearance on hover should use the same graceful transition (duration-700 ease-out) as the existing scroll-based visibility
|
|
3. Mobile navigation behavior remains completely unchanged
|
|
|
|
**Integration Requirements:**
|
|
4. Existing scroll-based navigation visibility continues to work unchanged
|
|
5. New hover functionality follows existing CSS transition pattern
|
|
6. Integration with current state management (`isScrolled`, mobile menu) maintains current behavior
|
|
|
|
**Quality Requirements:**
|
|
7. Change is covered by appropriate tests
|
|
8. No regression in existing mobile/desktop navigation functionality verified
|
|
9. Hover area is intuitive and appropriately sized
|
|
|
|
## Technical Notes
|
|
|
|
- **Integration Approach:** Add hover state detection and modify existing CSS classes to include hover pseudo-classes for desktop breakpoints only
|
|
- **Existing Pattern Reference:** Current opacity/pointer-events toggle pattern with `lg:opacity-0 lg:pointer-events-none` when not scrolled
|
|
- **Key Constraints:**
|
|
- Must not affect mobile behavior (mobile nav is always visible when not scrolled)
|
|
- Must maintain existing 700ms transition duration
|
|
- Hover area should be reasonable (likely top 80-100px of viewport)
|
|
|
|
## Definition of Done
|
|
|
|
- [ ] Functional requirements met
|
|
- [ ] Integration requirements verified
|
|
- [ ] Existing functionality regression tested
|
|
- [ ] Code follows existing patterns and standards
|
|
- [ ] Tests pass (existing and new)
|
|
- [ ] Documentation updated if applicable
|
|
|
|
## Risk and Compatibility Check
|
|
|
|
**Minimal Risk Assessment:**
|
|
- **Primary Risk:** Hover functionality interfering with mobile touch interactions or existing scroll behavior
|
|
- **Mitigation:** Use desktop-only CSS breakpoint modifiers (lg:) and test thoroughly on mobile devices
|
|
- **Rollback:** Simple CSS class modification revert, no state management changes needed
|
|
|
|
**Compatibility Verification:**
|
|
- [ ] No breaking changes to existing APIs
|
|
- [ ] Database changes: None
|
|
- [ ] UI changes follow existing design patterns (same transition, same styling)
|
|
- [ ] Performance impact is negligible (pure CSS hover, no additional JavaScript)
|
|
|
|
## Validation Checklist
|
|
|
|
**Scope Validation:**
|
|
- [ ] Story can be completed in one development session (estimated 2-3 hours)
|
|
- [ ] Integration approach is straightforward (CSS modification with existing patterns)
|
|
- [ ] Follows existing patterns exactly (same transitions, same conditional styling approach)
|
|
- [ ] No design or architecture work required
|
|
|
|
**Clarity Check:**
|
|
- [ ] Story requirements are unambiguous
|
|
- [ ] Integration points are clearly specified (navigation component only)
|
|
- [ ] Success criteria are testable (hover behavior, transition timing, mobile unchanged)
|
|
- [ ] Rollback approach is simple (revert CSS classes)
|
|

## Product Owner Validation Report
|
|
|
|
### Template Compliance Issues
|
|
|
|
**CRITICAL - Missing Required Sections:**
|
|
- Tasks / Subtasks section missing (required for dev agent implementation)
|
|
- Dev Notes section not following template structure (has "Technical Notes" instead)
|
|
- Testing section missing (only referenced in DoD)
|
|
- Change Log section missing
|
|
- Dev Agent Record section missing
|
|
- QA Results section missing
|
|
|
|
**Structure Issues:**
|
|
- Story uses custom structure instead of template format
|
|
- Missing proper elicitation markers and section ownership
|
|
|
|
### Critical Issues (Must Fix - Story Blocked)
|
|
|
|
1. **Missing Tasks/Subtasks Breakdown**: Story lacks the granular task breakdown required for dev agent implementation. Current story has high-level requirements but no actionable implementation steps.
|
|
|
|
2. **Navigation Component Syntax Error**: The existing `components/navigation.tsx` file has a syntax error (`const [a`) that must be fixed before any enhancements.
|
|
|
|
3. **Incomplete Dev Notes**: Current "Technical Notes" section lacks:
|
|
- Relevant source tree information
|
|
- Complete technical context for dev agent
|
|
- Testing standards and frameworks
|
|
- Specific implementation guidance
|
|
|
|
4. **Missing Testing Section**: No dedicated testing section with:
|
|
- Test file locations
|
|
- Testing frameworks to use
|
|
- Specific test scenarios for hover functionality
|
|
|
|
### Should-Fix Issues (Important Quality Improvements)
|
|
|
|
1. **Acceptance Criteria Clarity**: AC #9 mentions "appropriately sized" hover area but lacks specific dimensions (story mentions 80-100px but not in AC)
|
|
|
|
2. **Integration Context Missing**: Story doesn't specify how hover state will integrate with existing `isScrolled` state management
|
|
|
|
3. **Browser Compatibility**: No mention of hover behavior on touch devices or hybrid devices
|
|
|
|
### Anti-Hallucination Findings
|
|
|
|
**Verified Technical Claims:**
|
|
- ✅ Navigation component exists at `components/navigation.tsx`
|
|
- ✅ Current CSS classes `lg:opacity-0 lg:pointer-events-none` confirmed
|
|
- ✅ Transition duration `duration-700 ease-out` confirmed
|
|
- ✅ Scroll threshold of 50px confirmed in code
|
|
|
|
**Issues Requiring Source Verification:**
|
|
- ❌ Syntax error in navigation.tsx needs immediate attention
|
|
- ⚠️ Hover area size (80-100px) mentioned in Technical Notes but not in official AC
|
|
|
|
### Final Assessment
|
|
|
|
**Status: NO-GO** - Story requires critical fixes before implementation
|
|
|
|
**Implementation Readiness Score:** 3/10
|
|
|
|
**Confidence Level:** LOW
|
|
|
|
**Required Actions Before Implementation:**
|
|
1. Fix syntax error in `components/navigation.tsx`
|
|
2. Add proper Tasks/Subtasks section following template
|
|
3. Restructure Dev Notes section per template requirements
|
|
4. Add Testing section with specific test requirements
|
|
5. Add missing template sections (Change Log, Dev Agent Record)
|
|
6. Clarify hover area dimensions in Acceptance Criteria
|
|
|
|
**Recommendation:** Return to Scrum Master for story restructuring using proper template format.
