feat(git-hooks): implement conditional Husky activation system

- Implements conditional activation logic in husky.sh helper script
- Updates pre-commit hook to run linting only when enabled
- Updates commit-msg hook to validate messages only when enabled
- Adds .husky-enabled to .gitignore for user-specific activation
- Creates user activation instructions in .husky/README.md
- Provides graceful fallback when hooks are disabled

Activation: Environment variable, local file, or global config
Hooks: Pre-commit (linting) and commit-msg (validation)
Behavior: Optional activation with helpful instructions when disabled

+# Unit Testing & Mocks — Universal Development Guide
+
+**Author**: Matthew Raymer
+**Date**: 2025-08-21T09:40Z
+**Status**: 🎯 **ACTIVE** - Comprehensive testing standards
+
+## Overview
+
+This guide establishes **unified unit testing and mocking standards** for Vue 
+and React projects, ensuring consistent, maintainable test patterns using 
+Vitest, JSDOM, and component testing utilities. All tests follow F.I.R.S.T. 
+principles with comprehensive mock implementations.
+
+## Scope and Goals
+
+**Scope**: Applies to all unit tests, mock implementations, and testing 
+infrastructure in any project workspace.
+
+**Goal**: One consistent testing approach with comprehensive mock coverage, 
+100% test coverage for simple components, and maintainable test patterns.
+
+## Non‑Negotiables (DO THIS)
+
+- **MUST** use Vitest + JSDOM for unit testing; **DO NOT** use Jest or other 
+  frameworks
+- **MUST** implement comprehensive mock levels (Simple, Standard, Complex) for 
+  all components
+- **MUST** achieve 100% line coverage for simple components (<100 lines)
+- **MUST** follow F.I.R.S.T. principles: Fast, Independent, Repeatable, 
+  Self-validating, Timely
+- **MUST** use centralized test utilities from `src/test/utils/`
+
+## Testing Infrastructure
+
+### **Core Technologies**
+
+- **Vitest**: Fast unit testing framework with Vue/React support
+- **JSDOM**: Browser-like environment for Node.js testing
+- **@vue/test-utils**: Vue component testing utilities
+- **TypeScript**: Full type safety for tests and mocks
+
+### **Configuration Files**
+
+- `vitest.config.ts` - Vitest configuration with JSDOM environment
+- `src/test/setup.ts` - Global test configuration and mocks
+- `src/test/utils/` - Centralized testing utilities
+
+### **Global Mocks**
+
+```typescript
+// Required browser API mocks
+ResizeObserver, IntersectionObserver, localStorage, sessionStorage,
+matchMedia, console methods (reduced noise)
+```
+
+## Mock Implementation Standards
+
+### **Mock Architecture Levels**
+
+#### **1. Simple Mock (Basic Testing)**
+
+```typescript
+// Minimal interface compliance
+class ComponentSimpleMock {
+  // Essential props and methods only
+  // Basic computed properties
+  // No complex behavior
+}
+```
+
+#### **2. Standard Mock (Integration Testing)**
+
+```typescript
+// Full interface compliance
+class ComponentStandardMock {
+  // All props, methods, computed properties
+  // Realistic behavior simulation
+  // Helper methods for test scenarios
+}
+```
+
+#### **3. Complex Mock (Advanced Testing)**
+
+```typescript
+// Enhanced testing capabilities
+class ComponentComplexMock extends ComponentStandardMock {
+  // Mock event listeners
+  // Performance testing hooks
+  // Error scenario simulation
+  // Accessibility testing support
+}
+```
+
+### **Mock Component Structure**
+
+Each mock component provides:
+
+- Same interface as original component
+- Simplified behavior for testing
+- Helper methods for test scenarios
+- Computed properties for state validation
+
+### **Enhanced Mock Architecture Validation** ✅ **NEW**
+
+The three-tier mock architecture (Simple/Standard/Complex) has been successfully 
+validated through real-world implementation:
+
+#### **Tier 1: Simple Mock**
+
+```typescript
+class ComponentSimpleMock {
+  // Basic interface compliance
+  // Minimal implementation for simple tests
+  // Fast execution for high-volume testing
+}
+```
+
+#### **Tier 2: Standard Mock**
+
+```typescript
+class ComponentStandardMock {
+  // Full interface implementation
+  // Realistic behavior simulation
+  // Helper methods for common scenarios
+}
+```
+
+#### **Tier 3: Complex Mock**
+
+```typescript
+class ComponentComplexMock {
+  // Enhanced testing capabilities
+  // Validation and error simulation
+  // Advanced state management
+  // Performance testing support
+}
+```
+
+#### **Factory Function Pattern**
+
+```typescript
+// Specialized factory functions for common use cases
+export const createComponentMock = () =>
+  new ComponentStandardMock({ type: 'default' })
+
+export const createSpecializedMock = () =>
+  new ComponentComplexMock({
+    options: { filter: 'active', sort: 'name' }
+  })
+```
+
+### **Mock Usage Examples**
+
+```typescript
+export default class ComponentMock {
+  // Props simulation
+  props: ComponentProps
+
+  // Computed properties
+  get computedProp(): boolean {
+    return this.props.condition
+  }
+
+  // Mock methods
+  mockMethod(): void {
+    // Simulate behavior
+  }
+
+  // Helper methods
+  getCssClasses(): string[] {
+    return ['base-class', 'conditional-class']
+  }
+}
+```
+
+## Test Patterns
+
+### **Component Testing Template**
+
+```typescript
+import { mount } from '@vue/test-utils'
+import { createComponentWrapper } from '@/test/utils/componentTestUtils'
+
+describe('ComponentName', () => {
+  let wrapper: VueWrapper<any>
+
+  const mountComponent = (props = {}) => {
+    return mount(ComponentName, {
+      props: { ...defaultProps, ...props }
+    })
+  }
+
+  beforeEach(() => {
+    wrapper = mountComponent()
+  })
+
+  afterEach(() => {
+    wrapper?.unmount()
+  })
+
+  describe('Component Rendering', () => {
+    it('should render correctly', () => {
+      expect(wrapper.exists()).toBe(true)
+    })
+  })
+})
+```
+
+### **Mock Integration Testing**
+
+```typescript
+import ComponentMock from '@/test/__mocks__/Component.mock'
+
+it('should work with mock component', () => {
+  const mock = new ComponentMock()
+  expect(mock.shouldShow).toBe(true)
+})
+```
+
+### **Event Testing**
+
+```typescript
+it('should emit event when triggered', async () => {
+  await wrapper.find('button').trigger('click')
+  expect(wrapper.emitted('event-name')).toBeTruthy()
+})
+```
+
+### **Prop Validation**
+
+```typescript
+it('should accept all required props', () => {
+  wrapper = mountComponent()
+  expect(wrapper.vm.propName).toBeDefined()
+})
+```
+
+## Test Categories
+
+### **Required Coverage Areas**
+
+1. **Component Rendering** - Existence, structure, conditional rendering
+2. **Component Styling** - CSS classes, responsive design, framework 
+   integration
+3. **Component Props** - Required/optional prop handling, type validation
+4. **User Interactions** - Click events, form inputs, keyboard navigation
+5. **Component Methods** - Method existence, functionality, return values
+6. **Edge Cases** - Empty/null props, rapid interactions, state changes
+7. **Error Handling** - Invalid props, malformed data, graceful degradation
+8. **Accessibility** - Semantic HTML, ARIA attributes, keyboard navigation
+9. **Performance** - Render time, memory leaks, rapid re-renders
+10. **Integration** - Parent-child interaction, dependency injection
+
+### **Error Handling Testing**
+
+```typescript
+const invalidPropCombinations = [
+  null, undefined, 'invalid', 0, -1, {}, [],
+  () => {}, NaN, Infinity
+]
+
+invalidPropCombinations.forEach(invalidProp => {
+  it(`should handle invalid prop: ${invalidProp}`, () => {
+    wrapper = mountComponent({ prop: invalidProp })
+    expect(wrapper.exists()).toBe(true)
+    // Verify graceful handling
+  })
+})
+```
+
+## Centralized Test Utilities
+
+### **Component Testing Utilities**
+
+```typescript
+import {
+  createComponentWrapper,
+  createTestDataFactory,
+  testLifecycleEvents,
+  testComputedProperties,
+  testWatchers,
+  testPerformance,
+  testAccessibility,
+  testErrorHandling
+} from '@/test/utils/componentTestUtils'
+
+// Component wrapper factory
+const wrapperFactory = createComponentWrapper(
+  Component,
+  defaultProps,
+  globalOptions
+)
+
+// Test data factory
+const createTestProps = createTestDataFactory({
+  prop1: 'default',
+  prop2: true
+})
+```
+
+### **Test Data Factories**
+
+```typescript
+import {
+  createMockContact,
+  createMockProject,
+  createMockUser
+} from '@/test/factories/contactFactory'
+
+const testContact = createMockContact({
+  id: 'test-1',
+  name: 'Test User'
+})
+```
+
+## Coverage Standards
+
+### **Coverage Standards by Component Complexity**
+
+| Component Complexity | Line Coverage | Branch Coverage | Function Coverage |
+|---------------------|---------------|-----------------|-------------------|
+| **Simple (<100 lines)** | 100% | 100% | 100% |
+| **Medium (100-300 lines)** | 95% | 90% | 100% |
+| **Complex (300+ lines)** | 90% | 85% | 100% |
+
+### **Current Coverage Status**
+
+- **Simple Components**: Ready for implementation
+- **Medium Components**: Ready for expansion
+- **Complex Components**: Ready for expansion
+- **Overall Coverage**: Varies by project implementation
+
+### **Test Infrastructure Requirements**
+
+- **Test Framework**: Vitest + JSDOM recommended
+- **Component Testing**: Vue Test Utils integration
+- **Mock Architecture**: Three-tier system (Simple/Standard/Complex)
+- **Test Categories**: 10 comprehensive categories
+- **Coverage Goals**: 100% for simple components, 90%+ for complex
+
+## Testing Philosophy
+
+### **Defensive Programming Validation**
+
+- **Real-world edge case protection** against invalid API responses
+- **System stability assurance** preventing cascading failures
+- **Production readiness** ensuring graceful error handling
+
+### **Comprehensive Error Scenarios**
+
+- **Invalid input testing** with 10+ different invalid prop combinations
+- **Malformed data testing** with various corrupted data structures
+- **Extreme value testing** with boundary conditions and edge cases
+- **Concurrent error testing** with rapid state changes
+
+### **Benefits Beyond Coverage**
+
+1. **Defensive Programming Validation** - Components handle unexpected data 
+   gracefully
+2. **Real-World Resilience** - Tested against actual failure scenarios
+3. **Developer Confidence** - Safe to refactor and extend components
+4. **Production Stability** - Reduced support tickets and user complaints
+
+## Advanced Testing Patterns
+
+### **Performance Testing** ✅ **NEW**
+
+- Render time benchmarks
+- Memory leak detection
+- Rapid re-render efficiency
+- Component cleanup validation
+
+#### **Advanced Performance Testing Patterns**
+
+```typescript
+// Memory leak detection
+it('should not cause memory leaks during prop changes', async () => {
+  const initialMemory = (performance as any).memory?.usedJSHeapSize || 0
+
+  for (let i = 0; i < 100; i++) {
+    await wrapper.setProps({
+      queryParams: { iteration: i.toString() }
+    })
+  }
+
+  const finalMemory = (performance as any).memory?.usedJSHeapSize || 0
+  const memoryIncrease = finalMemory - initialMemory
+
+  // Memory increase should be reasonable (less than 10MB)
+  expect(memoryIncrease).toBeLessThan(10 * 1024 * 1024)
+})
+
+// Rapid re-render efficiency
+it('should handle rapid re-renders efficiently', async () => {
+  const start = performance.now()
+
+  for (let i = 0; i < 50; i++) {
+    await wrapper.setProps({
+      entityType: i % 2 === 0 ? 'type1' : 'type2',
+      queryParams: { index: i.toString() }
+    })
+  }
+
+  const end = performance.now()
+  expect(end - start).toBeLessThan(500) // 500ms threshold for 50 updates
+})
+```
+
+### **Snapshot Testing** ✅ **NEW**
+
+- DOM structure validation
+- CSS class regression detection
+- Accessibility attribute consistency
+- Visual structure verification
+
+#### **Snapshot Testing Implementation**
+
+```typescript
+describe('Snapshot Testing', () => {
+  it('should maintain consistent DOM structure', () => {
+    expect(wrapper.html()).toMatchSnapshot()
+  })
+
+  it('should maintain consistent structure with different props', () => {
+    wrapper = mountComponent({ type: 'alternative' })
+    expect(wrapper.html()).toMatchSnapshot()
+  })
+
+  it('should maintain consistent structure with query params', () => {
+    wrapper = mountComponent({
+      queryParams: { filter: 'active', sort: 'name' }
+    })
+    expect(wrapper.html()).toMatchSnapshot()
+  })
+})
+```
+
+### **Mock Integration Testing** ✅ **NEW**
+
+- Mock component validation
+- Factory function testing
+- Mock behavior verification
+- Integration with testing utilities
+
+#### **Mock Integration Testing Patterns**
+
+```typescript
+describe('Mock Integration Testing', () => {
+  it('should work with simple mock', () => {
+    const mock = new ComponentSimpleMock()
+    expect(mock.navigationRoute).toEqual({
+      name: 'default',
+      query: {}
+    })
+  })
+
+  it('should work with standard mock', () => {
+    const mock = new ComponentStandardMock({
+      type: 'special',
+      name: 'test'
+    })
+    expect(mock.getType()).toBe('special')
+    expect(mock.getName()).toBe('test')
+  })
+
+  it('should work with complex mock', () => {
+    const mock = new ComponentComplexMock({
+      type: 'advanced',
+      options: { filter: 'active' }
+    })
+
+    expect(mock.isValidState()).toBe(true)
+    expect(mock.getValidationErrors()).toEqual([])
+  })
+
+  it('should work with factory functions', () => {
+    const defaultMock = createComponentMock()
+    const specializedMock = createSpecializedMock()
+
+    expect(defaultMock.getType()).toBe('default')
+    expect(specializedMock.getOptions()).toHaveProperty('filter')
+  })
+})
+```
+
+## Project Implementation Tracking
+
+### **Setting Up Project-Specific Tracking**
+
+Each project should maintain its own tracking file to monitor testing progress 
+and coverage metrics. This keeps the universal MDC clean while providing a 
+template for project implementation.
+
+#### **Recommended Project Tracking Structure**
+
+```tree
+src/test/
+├── README.md                       # Testing documentation
+├── PROJECT_COVERAGE_TRACKING.md    # Project-specific progress tracking
+├── __mocks__/                      # Mock implementations
+├── utils/                          # Test utilities
+└── [test files]
+```
+
+#### **Project Tracking File Template**
+
+Create a `PROJECT_COVERAGE_TRACKING.md` file with:
+
+- **Current Coverage Status**: Component-by-component breakdown
+- **Implementation Progress**: Phase completion status
+- **Test Infrastructure Status**: Framework setup and metrics
+- **Next Steps**: Immediate priorities and long-term goals
+- **Lessons Learned**: Project-specific insights and best practices
+
+#### **Example Project Tracking Sections**
+
+```markdown
+# [Project Name] Testing Coverage Tracking
+
+## Current Coverage Status
+- Simple Components: X/Y at 100% coverage
+- Medium Components: X/Y ready for expansion
+- Complex Components: X/Y planned
+
+## Implementation Progress
+- Phase 1: Simple Components ✅ COMPLETE
+- Phase 2: Medium Components 🔄 IN PROGRESS
+- Phase 3: Complex Components 🔄 PLANNED
+
+## Test Infrastructure Status
+- Total Tests: X tests passing
+- Test Files: X files
+- Mock Files: X implementations
+- Overall Coverage: X% (focused on simple components)
+```
+
+### **Integration with Universal MDC**
+
+- **MDC provides**: Testing patterns, mock architecture, best practices
+- **Project tracking provides**: Implementation status, coverage metrics, 
+  progress
+- **Separation ensures**: MDC remains reusable, project data stays local
+- **Template approach**: Other projects can copy and adapt the structure
+
+### **Benefits of This Approach**
+
+1. **Universal Reusability**: MDC works for any project
+2. **Project Visibility**: Clear tracking of implementation progress
+3. **Template Reuse**: Easy to set up tracking in new projects
+4. **Clean Separation**: No project data polluting universal guidance
+5. **Scalability**: Multiple projects can use the same MDC
+
+## Best Practices
+
+### **Test Organization**
+
+1. **Group related tests** using `describe` blocks
+2. **Use descriptive test names** that explain the scenario
+3. **Keep tests focused** on one specific behavior
+4. **Use helper functions** for common setup
+
+### **Mock Design**
+
+1. **Maintain interface compatibility** with original components
+2. **Provide helper methods** for common test scenarios
+3. **Include computed properties** for state validation
+4. **Document mock behavior** clearly
+
+### **Coverage Goals**
+
+1. **100% line coverage** for simple components
+2. **100% branch coverage** for conditional logic
+3. **100% function coverage** for all methods
+4. **Edge case coverage** for error scenarios
+
+### **Lessons Learned from Implementation** ✅ **NEW**
+
+#### **1. Performance Testing Best Practices**
+
+- **Memory leak detection**: Use `performance.memory.usedJSHeapSize` for 
+  memory profiling
+- **Render time benchmarking**: Set realistic thresholds (100ms for single 
+  render, 500ms for 50 updates)
+- **Rapid re-render testing**: Test with 50+ prop changes to ensure 
+  stability
+
+#### **2. Snapshot Testing Implementation**
+
+- **DOM structure validation**: Use `toMatchSnapshot()` for consistent 
+  structure verification
+- **Prop variation testing**: Test snapshots with different prop combinations
+- **Regression prevention**: Snapshots catch unexpected DOM changes
+
+#### **3. Mock Integration Validation**
+
+- **Mock self-testing**: Test that mocks work correctly with testing 
+  utilities
+- **Factory function testing**: Validate specialized factory functions
+- **Mock behavior verification**: Ensure mocks simulate real component 
+  behavior
+
+#### **4. Edge Case Coverage**
+
+- **Null/undefined handling**: Test with `null as any` and `undefined` 
+  props
+- **Extreme values**: Test with very long strings and large numbers
+- **Rapid changes**: Test with rapid prop changes to ensure stability
+
+#### **5. Accessibility Testing**
+
+- **Semantic structure**: Verify proper HTML elements and hierarchy
+- **Component attributes**: Check component-specific attributes
+- **Text content**: Validate text content and trimming
+
+## Future Improvements
+
+### **Implemented Enhancements**
+
+1. ✅ **Error handling** - Component error states and exception handling
+2. ✅ **Performance testing** - Render time benchmarks and memory leak 
+   detection
+3. ✅ **Integration testing** - Parent-child component interaction and 
+   dependency injection
+4. ✅ **Snapshot testing** - DOM structure validation and CSS class 
+   regression detection
+5. ✅ **Accessibility compliance** - ARIA attributes and semantic structure 
+   validation
+
+### **Future Enhancements**
+
+1. **Visual regression testing** - Automated UI consistency checks
+2. **Cross-browser compatibility** testing
+3. **Service layer integration** testing
+4. **End-to-end component** testing
+5. **Advanced performance** profiling
+
+### **Coverage Expansion**
+
+1. **Medium complexity components** (100-300 lines)
+2. **Complex components** (300+ lines)
+3. **Service layer testing**
+4. **Utility function testing**
+5. **API integration testing**
+
+## Troubleshooting
+
+### **Common Issues**
+
+1. **Import errors**: Check path aliases in `vitest.config.ts`
+2. **Mock not found**: Verify mock file exists and exports correctly
+3. **Test failures**: Check for timing issues with async operations
+4. **Coverage gaps**: Add tests for uncovered code paths
+
+### **Debug Tips**
+
+1. **Use `console.log`** in tests for debugging
+2. **Check test output** for detailed error messages
+3. **Verify component props** are being passed correctly
+4. **Test one assertion at a time** to isolate issues
+
+---
+
+**Status**: Active testing standards
+**Priority**: High
+**Estimated Effort**: Ongoing reference
+**Dependencies**: Vitest, JSDOM, Vue Test Utils
+**Stakeholders**: Development team, QA team
+

+# Husky Conditional Activation System
+
+**Author**: Matthew Raymer
+**Date**: 2025-08-21T09:40Z
+**Status**: 🎯 **ACTIVE** - Git hooks with optional activation
+
+## Overview
+
+This document describes the **conditional Husky activation system** implemented
+in the TimeSafari project. The system provides standardized git hooks that are
+committed to version control but only activate when explicitly enabled by
+individual developers.
+
+## Problem Statement
+
+Traditional Husky implementations face several challenges:
+
+1. **Automatic activation** on all systems can be disruptive
+2. **Different environments** may have different requirements
+3. **Team preferences** vary regarding git hook enforcement
+4. **CI/CD systems** may not need or want git hooks
+5. **New developers** may be surprised by unexpected hook behavior
+
+## Solution: Conditional Activation
+
+The conditional activation system solves these problems by:
+
+- **Committing hooks to git** for consistency and version control
+- **Making hooks optional** by default
+- **Providing multiple activation methods** for flexibility
+- **Ensuring hooks exit gracefully** when disabled
+- **Maintaining team standards** without forcing compliance
+
+## System Architecture
+
+### **Core Components**
+
+```
+.husky/
+├── _/husky.sh              # Conditional activation logic
+├── pre-commit              # Pre-commit hook (linting)
+├── commit-msg              # Commit message validation
+└── README.md               # User activation instructions
+```
+
+### **Activation Methods**
+
+#### **Method 1: Environment Variable (Session Only)**
+
+```bash
+export HUSKY_ENABLED=1
+```
+
+- **Scope**: Current terminal session only
+- **Use case**: Temporary activation for testing
+- **Reset**: `unset HUSKY_ENABLED`
+
+#### **Method 2: Local File (Persistent)**
+
+```bash
+touch .husky-enabled
+```
+
+- **Scope**: Current repository, persistent
+- **Use case**: Long-term activation for development
+- **Reset**: `rm .husky-enabled`
+
+#### **Method 3: Global Git Configuration**
+
+```bash
+git config --global husky.enabled true
+```
+
+- **Scope**: All repositories for current user
+- **Use case**: Developer preference across projects
+- **Reset**: `git config --global --unset husky.enabled`
+
+## Implementation Details
+
+### **Conditional Activation Logic**
+
+The core logic in `.husky/_/husky.sh`:
+
+```bash
+# Check if Husky is enabled for this user
+if [ "$HUSKY_ENABLED" != "1" ] && [ ! -f .husky-enabled ]; then
+  echo "Husky is not enabled. To enable:"
+  echo "  export HUSKY_ENABLED=1"
+  echo "  or create .husky-enabled file"
+  exit 0  # Graceful exit, not an error
+fi
+```
+
+### **Hook Behavior**
+
+When **disabled**:
+
+- Hooks display helpful activation instructions
+- Exit with code 0 (success, not error)
+- No git operations are blocked
+- No performance impact
+
+When **enabled**:
+
+- Hooks run normally with full functionality
+- Standard Husky behavior applies
+- Git operations may be blocked if hooks fail
+
+## Available Hooks
+
+### **Pre-commit Hook**
+
+**File**: `.husky/pre-commit`
+**Purpose**: Code quality enforcement before commits
+**Action**: Runs `npm run lint-fix`
+**When**: Before each commit
+**Failure**: Prevents commit if linting fails
+
+**Activation Check**:
+
+```bash
+if [ "$HUSKY_ENABLED" = "1" ] || [ -f .husky-enabled ]; then
+  echo "Running pre-commit hooks..."
+  npm run lint-fix
+else
+  echo "Husky pre-commit hook skipped (not enabled)"
+  exit 0
+fi
+```
+
+### **Commit-msg Hook**
+
+**File**: `.husky/commit-msg`
+**Purpose**: Commit message format validation
+**Action**: Runs `npx commitlint --edit "$1"`
+**When**: After commit message is written
+**Failure**: Prevents commit if message format is invalid
+
+**Activation Check**:
+
+```bash
+if [ "$HUSKY_ENABLED" = "1" ] || [ -f .husky-enabled ]; then
+  echo "Running commit-msg hooks..."
+  npx commitlint --edit "$1"
+else
+  echo "Husky commit-msg hook skipped (not enabled)"
+  exit 0
+fi
+```
+
+## User Workflows
+
+### **New Developer Setup**
+
+1. **Clone repository**
+
+   ```bash
+   git clone <repository-url>
+   cd <repository-name>
+   ```
+
+2. **Hooks are present but inactive**
+   - Pre-commit and commit-msg hooks exist
+   - No automatic activation
+   - Git operations work normally
+
+3. **Optional: Enable hooks**
+
+   ```bash
+   # For current session only
+   export HUSKY_ENABLED=1
+
+   # For persistent activation
+   touch .husky-enabled
+   ```
+
+### **Daily Development**
+
+#### **With Hooks Disabled**
+
+```bash
+git add .
+git commit -m "feat: add new feature"
+# Hooks are skipped, commit proceeds normally
+```
+
+#### **With Hooks Enabled**
+
+```bash
+git add .
+git commit -m "feat: add new feature"
+# Pre-commit hook runs linting
+# Commit-msg hook validates message format
+# Commit only proceeds if all hooks pass
+```
+
+### **Troubleshooting**
+
+#### **Hooks Not Running**
+
+```bash
+# Check if hooks are enabled
+echo $HUSKY_ENABLED
+ls -la .husky-enabled
+
+# Enable hooks
+export HUSKY_ENABLED=1
+# or
+touch .husky-enabled
+```
+
+#### **Hooks Running Unexpectedly**
+
+```bash
+# Disable hooks
+unset HUSKY_ENABLED
+rm -f .husky-enabled
+
+# Check global configuration
+git config --global --get husky.enabled
+```
+
+## Configuration Files
+
+### **`.gitignore` Entry**
+
+```gitignore
+# Husky activation file (user-specific)
+.husky-enabled
+```
+
+This ensures that:
+
+- Hooks are committed to git (team standard)
+- Activation files are not committed (user preference)
+- Each developer can control their own activation
+
+### **Package.json Dependencies**
+
+```json
+{
+  "devDependencies": {
+    "husky": "^9.0.11",
+    "@commitlint/cli": "^18.6.1",
+    "@commitlint/config-conventional": "^18.6.2"
+  }
+}
+```
+
+## Benefits

+
+## Troubleshooting Guide
+
+### **Common Issues**
+
+#### **Hooks Running When Not Expected**
+
+```bash
+# Check all activation methods
+echo "Environment variable: $HUSKY_ENABLED"
+echo "Local file exists: $([ -f .husky-enabled ] && echo "yes" || echo "no")"
+echo "Global config: $(git config --global --get husky.enabled)"
+```
+
+#### **Hooks Not Running When Expected**
+
+```bash
+# Verify hook files exist and are executable
+ls -la .husky/
+chmod +x .husky/pre-commit
+chmod +x .husky/commit-msg
+```
+
+#### **Permission Denied Errors**
+
+```bash
+# Fix file permissions
+chmod +x .husky/_/husky.sh
+chmod +x .husky/pre-commit
+chmod +x .husky/commit-msg
+```
+
+### **Debug Mode**
+
+Enable debug output to troubleshoot hook issues:
+
+```bash
+export HUSKY_DEBUG=1
+export HUSKY_ENABLED=1
+git commit -m "test: debug commit"
+```
+
+## Future Enhancements
+
+### **Planned Improvements**
+
+1. **Hook Configuration File**: YAML/JSON configuration for hook behavior
+2. **Selective Hook Activation**: Enable/disable specific hooks individually
+3. **Hook Performance Metrics**: Track execution time and success rates
+4. **Integration with IDEs**: IDE-specific activation methods
+5. **Remote Configuration**: Team-wide hook settings via configuration
+
+### **Extension Points**
+
+1. **Custom Hook Scripts**: Easy addition of project-specific hooks
+2. **Hook Templates**: Reusable hook patterns for common tasks
+3. **Conditional Logic**: Complex activation rules based on context
+4. **Notification System**: Hook status reporting and alerts
+5. **Analytics**: Hook usage and effectiveness tracking
+
+## Conclusion
+
+The conditional Husky activation system provides an elegant solution to the
+challenges  of git hook management in team environments. By committing
+standardized hooks while making activation optional, it balances consistency
+with flexibility, enabling teams to maintain coding standards without forcing compliance.
+
+This approach supports gradual adoption, respects individual preferences, and
+provides a solid foundation for git hook practices that can evolve with team needs
+and project requirements.

+- **Factory functions**: Specialized mock creation
+- **Interface compliance**: Full compatibility with original components
+- **Helper methods**: Common test scenario support
+
+### **Test Categories** ✅
+
+1. **Component Rendering** - Structure and conditional rendering
+2. **Component Styling** - CSS classes and responsive design
+3. **Component Props** - Validation and handling
+4. **User Interactions** - Events and accessibility
+5. **Component Methods** - Functionality and return values
+6. **Edge Cases** - Null/undefined and rapid changes
+7. **Error Handling** - Invalid props and graceful degradation
+8. **Accessibility** - Semantic HTML and ARIA
+9. **Performance** - Render time and memory leaks
+10. **Integration** - Parent-child and dependency injection
+
+### **Advanced Testing Features** ✅
+
+- **Performance Testing**: Memory leak detection, render time benchmarking
+- **Snapshot Testing**: DOM structure validation and regression prevention
+- **Mock Integration**: Mock component validation and testing
+- **Edge Case Coverage**: Comprehensive error scenario testing
+
+## Next Steps

+## Test Patterns
+
+### **1. Component Mounting**
+
+```typescript
+const mountComponent = (props = {}) => {
+  return mount(ComponentName, {
+    props: {
+      // Default props
+      ...props
+    }
+  })
+}
+```
+
+### **2. Event Testing**
+
+```typescript
+it('should emit event when clicked', async () => {
+  wrapper = mountComponent()
+  await wrapper.find('button').trigger('click')
+  expect(wrapper.emitted('event-name')).toBeTruthy()
+})
+```
+
+### **3. Prop Validation**
+
+```typescript
+it('should accept all required props', () => {
+  wrapper = mountComponent()
+  expect(wrapper.vm.propName).toBeDefined()
+})
+```
+
+### **4. CSS Class Testing**
+
+```typescript
+it('should have correct CSS classes', () => {
+  wrapper = mountComponent()
+  const element = wrapper.find('.selector')
+  expect(element.classes()).toContain('expected-class')
+})
+```

+## Testing Philosophy
+
+### **Defensive Programming Validation**
+
+The primary purpose of our comprehensive error handling tests is to **prevent 
+component and system failures** in real-world scenarios. Our testing philosophy 
+focuses on:
+
+#### **1. Real-World Edge Case Protection**
+
+- **Invalid API responses**: Test components when backend returns `null` instead 
+  of expected objects
+- **Network failures**: Verify graceful handling of missing or corrupted data
+- **User input errors**: Test with malformed data, special characters, and 
+  extreme values
+- **Concurrent operations**: Ensure stability during rapid state changes and 
+  simultaneous interactions
+
+#### **2. System Stability Assurance**
+
+- **Cascading failures**: Prevent one component's error from breaking the 
+  entire application
+- **Memory leaks**: Ensure components clean up properly even when errors occur
+- **Performance degradation**: Verify components remain responsive under error 
+  conditions
+
+#### **3. Production Readiness**
+
+- **User Experience Protection**: Users don't see blank screens or error 
+  messages
+- **Developer Confidence**: Safe refactoring without fear of breaking edge 
+  cases
+- **System Reliability**: Prevents one bad API response from crashing the 
+  entire app
+
+### **Comprehensive Error Scenarios**
+
+Our error handling tests cover:
+
+#### **RegistrationNotice Component Protection**
+
+- Prevents crashes when `isRegistered` or `show` props are malformed
+- Ensures the "Share Your Info" button still works even with invalid data
+- Protects against rapid prop changes causing UI inconsistencies
+
+#### **LargeIdenticonModal Component Protection**
+
+- Prevents modal rendering with invalid contact data that could break the UI
+- Ensures the close functionality works even with malformed contact objects
+- Protects against EntityIcon component failures cascading to the modal
+
+### **Error Testing Categories**
+
+#### **Invalid Input Testing**
+
+```typescript
+// Test 10+ different invalid prop combinations
+const invalidPropCombinations = [
+  null, undefined, 'invalid', 0, -1, {}, [], 
+  () => {}, NaN, Infinity
+]
+```
+
+#### **Malformed Data Testing**
+
+```typescript
+// Test various malformed data structures
+const malformedData = [
+  { id: 'invalid' }, { name: null }, 
+  { id: 0, name: '' }, { id: NaN, name: NaN }
+]
+```
+
+#### **Extreme Value Testing**
+
+```typescript
+// Test boundary conditions and extreme values
+const extremeValues = [
+  Number.MAX_SAFE_INTEGER, Number.MIN_SAFE_INTEGER,
+  Infinity, NaN, '', '\t\n\r'
+]
+```
+
+#### **Concurrent Error Testing**
+
+```typescript
+// Test rapid changes with invalid data
+for (let i = 0; i < 50; i++) {
+  await wrapper.setProps({ 
+    contact: i % 2 === 0 ? null : malformedContact 
+  })
+}
+```
+
+### **Benefits Beyond Coverage**
+
+#### **1. Defensive Programming Validation**
+
+- Components handle unexpected data gracefully
+- No crashes or blank screens for users
+- Proper error boundaries and fallbacks
+
+#### **2. Real-World Resilience**
+
+- Tested against actual failure scenarios
+- Validated with realistic error conditions
+- Proven stability under adverse conditions
+
+#### **3. Developer Confidence**
+
+- Safe to refactor and extend components
+- Clear understanding of component behavior under stress
+- Reduced debugging time for edge cases
+
+#### **4. Production Stability**
+
+- Reduced support tickets and user complaints
+- Improved application reliability
+- Better user experience under error conditions
+
+## Mock Implementation
+
+### **Mock Component Structure**
+
+Each mock component provides:
+
+- Same interface as original component
+- Simplified behavior for testing
+- Helper methods for test scenarios
+- Computed properties for state validation
+
+### **Mock Usage Examples**
+
+#### **Direct Instantiation**
+
+```typescript
+import RegistrationNoticeMock from '@/test/__mocks__/RegistrationNotice.mock'
+const mock = new RegistrationNoticeMock()
+expect(mock.shouldShow).toBe(true)
+```
+
+#### **Vue Test Utils Integration**
+
+```typescript
+import { mount } from '@vue/test-utils'
+import RegistrationNoticeMock from '@/test/__mocks__/RegistrationNotice.mock'
+
+const wrapper = mount(RegistrationNoticeMock, {
+  props: { isRegistered: false, show: true }
+})
+expect(wrapper.vm.shouldShow).toBe(true)
+```
+
+#### **Event Testing**
+
+```typescript
+const mock = new RegistrationNoticeMock()
+mock.mockShareInfoClick()
+// Verify event was emitted
+```
+
+#### **Custom Mock Behavior**
+
+```typescript
+class CustomRegistrationNoticeMock extends RegistrationNoticeMock {
+  get shouldShow(): boolean {
+    return false // Override for specific test scenario
+  }
+}
+```
+
+## Advanced Testing Patterns
+
+### **Spy Methods**
+
+```typescript
+import { vi } from 'vitest'
+
+it('should call method when triggered', () => {
+  const mockMethod = vi.fn()
+  wrapper = mountComponent()
+  wrapper.vm.someMethod = mockMethod
+  
+  wrapper.vm.triggerMethod()
+  expect(mockMethod).toHaveBeenCalled()
+})
+```
+
+### **Integration Testing**
+
+```typescript
+it('should work with parent component', () => {
+  const parentWrapper = mount(ParentComponent, {
+    global: {
+      stubs: {
+        ChildComponent: RegistrationNoticeMock
+      }
+    }
+  })
+  
+  expect(parentWrapper.findComponent(RegistrationNoticeMock).exists()).toBe(true)
+})
+```
+
+### **State Change Testing**
+
+```typescript
+it('should update state when props change', async () => {
+  wrapper = mountComponent({ show: false })
+  expect(wrapper.find('.notice').exists()).toBe(false)
+  
+  await wrapper.setProps({ show: true })
+  expect(wrapper.find('.notice').exists()).toBe(true)
+})
+```
+
+### **Performance Testing**
+
+```typescript
+it('should render within acceptable time', () => {
+  const start = performance.now()
+  wrapper = mountComponent()
+  const end = performance.now()
+  
+  expect(end - start).toBeLessThan(100) // 100ms threshold
+})
+```
+
+## Running Tests
+
+### **Available Commands**
+
+```bash
+# Run all tests
+npm run test:unit
+
+# Run tests in watch mode
+npm run test:unit:watch
+
+# Run tests with coverage
+npm run test:unit:coverage
+
+# Run specific test file
+npm run test:unit src/test/RegistrationNotice.test.ts
+```
+
+### **Test Output**
+
+- **Passing Tests**: Green checkmarks
+- **Failing Tests**: Red X with detailed error messages

+## Centralized Test Utilities
+
+### **Component Testing Utilities** (`src/test/utils/componentTestUtils.ts`)
+
+Provides consistent patterns for component testing across the application:
+
+#### **Component Wrapper Factory**
+
+```typescript
+import { createComponentWrapper } from '@/test/utils/componentTestUtils'
+
+// Create reusable wrapper factory
+const wrapperFactory = createComponentWrapper(
+  Component,
+  defaultProps,
+  globalOptions
+)
+
+// Use factory for consistent mounting
+const wrapper = wrapperFactory(customProps)
+```
+
+#### **Test Data Factory**
+
+```typescript
+import { createTestDataFactory } from '@/test/utils/componentTestUtils'
+
+// Create test data factory
+const createTestProps = createTestDataFactory({
+  isRegistered: false,
+  show: true
+})
+
+// Use with overrides
+const props = createTestProps({ show: false })
+```
+
+#### **Lifecycle Testing**
+
+```typescript
+import { testLifecycleEvents } from '@/test/utils/componentTestUtils'
+
+const results = await testLifecycleEvents(wrapper, ['mounted', 'updated'])
+expect(results.every(r => r.success)).toBe(true)
+```
+
+#### **Computed Properties Testing**
+
+```typescript
+import { testComputedProperties } from '@/test/utils/componentTestUtils'
+
+const results = testComputedProperties(wrapper, ['computedProp1', 'computedProp2'])
+expect(results.every(r => r.success)).toBe(true)
+```
+
+#### **Watcher Testing**
+
+```typescript
+import { testWatchers } from '@/test/utils/componentTestUtils'
+
+const watcherTests = [
+  { property: 'prop1', newValue: 'newValue' },
+  { property: 'prop2', newValue: false }
+]
+
+const results = await testWatchers(wrapper, watcherTests)
+expect(results.every(r => r.success)).toBe(true)
+```
+
+#### **Performance Testing**
+
+```typescript
+import { testPerformance } from '@/test/utils/componentTestUtils'
+
+const result = testPerformance(() => {
+  // Test function
+}, 100) // threshold in ms
+
+expect(result.passed).toBe(true)
+```
+
+#### **Accessibility Testing**
+
+```typescript
+import { testAccessibility } from '@/test/utils/componentTestUtils'
+
+const accessibilityChecks = [
+  {
+    name: 'has role',
+    test: (wrapper) => wrapper.find('[role="alert"]').exists()
+  }
+]
+
+const results = testAccessibility(wrapper, accessibilityChecks)
+expect(results.every(r => r.success && r.passed)).toBe(true)
+```
+
+#### **Error Handling Testing**
+
+```typescript
+import { testErrorHandling } from '@/test/utils/componentTestUtils'
+
+const errorScenarios = [
+  {
+    name: 'invalid prop',
+    action: async (wrapper) => {
+      await wrapper.setProps({ prop: 'invalid' })
+    },
+    expectedBehavior: 'should handle gracefully'
+  }
+]
+
+const results = await testErrorHandling(wrapper, errorScenarios)
+expect(results.every(r => r.success)).toBe(true)
+```
+
+#### **Event Listener Testing**
+
+```typescript
+import { createMockEventListeners } from '@/test/utils/componentTestUtils'
+
+const listeners = createMockEventListeners(['click', 'keydown'])
+expect(listeners.click).toBeDefined()
+```
+
+## Best Practices
+
+### **Test Organization**
+
+1. **Group related tests** using `describe` blocks
+2. **Use descriptive test names** that explain the scenario
+3. **Keep tests focused** on one specific behavior
+4. **Use helper functions** for common setup
+
+### **Mock Design**
+
+1. **Maintain interface compatibility** with original components
+2. **Provide helper methods** for common test scenarios
+3. **Include computed properties** for state validation
+4. **Document mock behavior** clearly
+
+### **Coverage Goals**
+
+1. **100% line coverage** for simple components
+2. **100% branch coverage** for conditional logic
+3. **100% function coverage** for all methods
+4. **Edge case coverage** for error scenarios
+
+## Future Improvements
+
+### **Implemented Enhancements**
+
+1. ✅ **Error handling** - Component error states and exception handling
+2. ✅ **Performance testing** - Render time benchmarks and memory leak detection
+3. ✅ **Integration testing** - Parent-child component interaction and dependency injection
+4. ✅ **Snapshot testing** - DOM structure validation and CSS class regression detection
+5. ✅ **Accessibility compliance** - ARIA attributes and semantic structure validation
+
+### **Future Enhancements**
+
+1. **Visual regression testing** - Automated UI consistency checks
+2. **Cross-browser compatibility** testing
+3. **Service layer integration** testing
+4. **End-to-end component** testing
+5. **Advanced performance** profiling
+
+### **Coverage Expansion**
+
+1. **Medium complexity components** (100-300 lines)
+2. **Complex components** (300+ lines)
+3. **Service layer testing**
+4. **Utility function testing**
+5. **API integration testing**
+
+## Troubleshooting
+
+### **Common Issues**
+
+1. **Import errors**: Check path aliases in `vitest.config.ts`
+2. **Mock not found**: Verify mock file exists and exports correctly
+3. **Test failures**: Check for timing issues with async operations
+4. **Coverage gaps**: Add tests for uncovered code paths
+
+### **Debug Tips**
+
+1. **Use `console.log`** in tests for debugging
+2. **Check test output** for detailed error messages
+3. **Verify component props** are being passed correctly
+4. **Test one assertion at a time** to isolate issues

+levels of complexity to support different testing scenarios and requirements.
+
+## Mock Architecture
+
+### Mock Levels Pattern
+
+All component mocks follow a consistent 4-level architecture:
+
+#### 1. Simple Mock (`createSimple[Component]Mock`)
+**Use Case**: Basic component testing, prop validation, minimal functionality
+- Basic template with minimal structure
+- Essential props and events
+- No complex behavior simulation
+- Fast execution for quick tests
+
+#### 2. Standard Mock (`createStandard[Component]Mock`)
+**Use Case**: Most component testing scenarios, realistic behavior
+- Full template with realistic structure
+- Platform detection and feature simulation
+- Realistic user interactions
+- Balanced performance and functionality
+
+#### 3. Complex Mock (`createComplex[Component]Mock`)
+**Use Case**: Error handling, edge cases, advanced scenarios
+- Error state simulation
+- Retry functionality
+- Loading state management
+- Error event emissions
+
+#### 4. Integration Mock (`createIntegration[Component]Mock`)
+**Use Case**: Full workflow testing, analytics, performance monitoring
+- Complete user workflow simulation
+- Analytics tracking
+- Performance monitoring
+- Comprehensive event handling
+
+## Mock Data Factories
+
+### Standard Factory Pattern
+
+```typescript
+// Generic mock data factory
+export const createMock[Component]Data = (overrides = {}) => ({
+  // Default props
+  prop1: "default-value",
+  prop2: false,
+  // Component-specific defaults
+  ...overrides,
+});
+
+// Platform-specific factories
+export const createMockUserAgent = (overrides = {}) => ({
+  getOS: () => ({ name: "iOS", version: "15.0" }),
+  getBrowser: () => ({ name: "Safari", version: "15.0" }),
+  getDevice: () => ({ type: "mobile", model: "iPhone" }),
+  ...overrides,
+});
+
+// API mocks
+export const createMockNavigator = (overrides = {}) => ({
+  share: jest.fn().mockResolvedValue(undefined),
+  ...overrides,
+});
+
+export const createMockWindow = (overrides = {}) => ({
+  open: jest.fn(),
+  URL: {
+    createObjectURL: jest.fn().mockReturnValue("blob:mock-url"),
+    revokeObjectURL: jest.fn(),
+  },
+  ...overrides,
+});
+```
+
+## Component Mock Template
+
+### Basic Structure

+    expectedBehavior: "Component renders with basic props",
+  },
+  // Additional scenarios
+});
+
+// Export default mock for easy import
+export default createStandard[Component]Mock();
+```
+
+## Usage Patterns
+
+### 1. Basic Component Testing
+
+```typescript
+describe("Basic Component Testing", () => {
+  it("renders with basic props", () => {
+    const createWrapper = create[Component]MockWrapper("simple");
+    const wrapper = createWrapper({
+      prop1: "test-value",
+      prop2: true,
+    });
+
+    expect(wrapper.exists()).toBe(true);
+    expect(wrapper.find(".component-mock").exists()).toBe(true);
+  });
+});
+```
+
+### 2. Platform-Specific Testing
+
+```typescript
+describe("Platform Detection", () => {
+  it("shows platform-specific features", () => {
+    const createWrapper = create[Component]MockWrapper("standard");
+    const wrapper = createWrapper(createMock[Component]Data());
+    
+    wrapper.vm.userAgent = createMockUserAgent({
+      getOS: () => ({ name: "iOS" })
+    });
+
+    expect(wrapper.vm.isMobile).toBe(true);
+  });
+});
+```
+
+### 3. Error Scenario Testing
+
+```typescript
+describe("Error Handling", () => {
+  it("handles API failures gracefully", async () => {
+    const createWrapper = create[Component]MockWrapper("standard");
+    const mockApi = vi.fn().mockRejectedValue(new Error("API failed"));
+    
+    const wrapper = createWrapper(createMock[Component]Data());
+
+    // Trigger error scenario
+    await wrapper.vm.handleApiCall();
+
+    expect(mockApi).toHaveBeenCalled();
+    expect(wrapper.vm.hasError).toBe(true);
+  });
+});
+```
+
+### 4. Integration Testing
+
+```typescript
+describe("Full User Workflow", () => {
+  it("completes full user journey", async () => {
+    const createWrapper = create[Component]MockWrapper("integration");
+    const wrapper = createWrapper(createMock[Component]Data({ isOpen: false }));
+
+    // Step 1: Initialize
+    await wrapper.setProps({ isOpen: true });
+    expect(wrapper.vm.getAnalytics().openCount).toBe(1);
+
+    // Step 2: User interaction
+    const button = wrapper.find('[data-testid="action-button"]');
+    await button.trigger("click");
+
+    // Step 3: Verify results
+    expect(wrapper.vm.getAnalytics().actionCount).toBe(1);
+  });
+});
+```
+
+## Best Practices
+
+### 1. Choose Appropriate Mock Level
+
+- Use **simple** for basic prop validation and rendering tests
+- Use **standard** for most component behavior tests
+- Use **complex** for error handling and edge case tests
+- Use **integration** for full workflow and analytics tests
+
+### 2. Mock Global Objects
+
+```typescript
+beforeEach(() => {
+  mockNavigator = createMockNavigator();
+  mockWindow = createMockWindow();
+  global.navigator = mockNavigator;
+  global.window = mockWindow;
+  vi.clearAllMocks();
+});
+```
+
+### 3. Test Platform Detection
+
+```typescript
+const platforms = [
+  { name: "iOS", expected: true },
+  { name: "Android", expected: true },
+  { name: "Windows", expected: false },
+];
+
+platforms.forEach(({ name, expected }) => {
+  wrapper.vm.userAgent = createMockUserAgent({
+    getOS: () => ({ name, version: "1.0" }),
+  });
+  expect(wrapper.vm.isMobile).toBe(expected);
+});
+```
+
+### 4. Test Error Scenarios
+
+```typescript
+// Test API failure
+const mockApi = vi.fn().mockRejectedValue(new Error("API failed"));
+mockNavigator.share = mockApi;
+
+// Test component error
+const element = wrapper.find('[data-testid="component-element"]');
+await element.trigger("error");
+expect(wrapper.vm.hasError).toBe(true);
+```
+
+### 5. Use Test Data Factories
+
+```typescript
+// Instead of hardcoded data
+const wrapper = createWrapper({
+  prop1: "test-value",
+  prop2: true,
+});
+
+// Use factory functions
+const wrapper = createWrapper(createMock[Component]Data({
+  prop1: "test-value",
+  prop2: true,
+}));
+```
+
+## Performance Considerations
+
+### 1. Mock Level Performance
+
+- **Simple**: Fastest execution, minimal overhead
+- **Standard**: Good balance of features and performance
+- **Complex**: Moderate overhead for error handling
+- **Integration**: Highest overhead for analytics tracking
+
+### 2. Test Execution Tips
+
+```typescript
+// Use simple mock for quick tests
+const createWrapper = create[Component]MockWrapper("simple");
+
+// Use standard mock for most tests
+const createWrapper = create[Component]MockWrapper("standard");
+
+// Use complex/integration only when needed
+const createWrapper = create[Component]MockWrapper("complex");
+```
+
+## Accessibility Testing
+
+### 1. ARIA Labels
+
+```typescript
+it("has proper ARIA labels", () => {
+  const wrapper = createWrapper(createMock[Component]Data());
+  const element = wrapper.find('[data-testid="component-element"]');
+  expect(element.attributes("alt")).toBe("descriptive text");
+});
+```
+
+### 2. Keyboard Navigation
+
+```typescript
+it("supports keyboard navigation", async () => {
+  const wrapper = createWrapper(createMock[Component]Data());
+  const button = wrapper.find('[data-testid="action-button"]');
+  
+  await button.trigger("keydown.enter");
+  expect(wrapper.emitted("action")).toBeTruthy();
+});
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Mock not found**: Ensure proper import path
+```typescript
+import { create[Component]MockWrapper } from "./__mocks__/[Component].mock";
+```
+
+2. **Global objects not mocked**: Set up in beforeEach
+```typescript
+beforeEach(() => {
+  global.navigator = createMockNavigator();
+  global.window = createMockWindow();
+});
+```
+
+3. **User agent not working**: Set userAgent property directly
+```typescript
+wrapper.vm.userAgent = createMockUserAgent({
+  getOS: () => ({ name: "iOS" })
+});
+```
+
+4. **Events not emitting**: Use async/await for event triggers
+```typescript
+await button.trigger("click");
+await wrapper.vm.$nextTick();
+```
+
+### Debug Tips
+
+1. **Check mock level**: Verify you're using the right mock level
+2. **Inspect wrapper**: Use `console.log(wrapper.html())` to see rendered output
+3. **Check props**: Use `console.log(wrapper.props())` to verify prop values
+4. **Monitor events**: Use `console.log(wrapper.emitted())` to see emitted events
+
+## Migration from Legacy Tests
+
+### Before (Legacy)
+
+```typescript
+// Old way - direct component testing
+const wrapper = mount(Component, {
+  props: { prop1: "test", prop2: true },
+  global: { stubs: { "font-awesome": true } }
+});
+```
+
+### After (Mock Units)
+
+```typescript
+// New way - behavior-focused testing
+const createWrapper = create[Component]MockWrapper("standard");
+const wrapper = createWrapper(createMock[Component]Data({ prop1: "test" }));
+
+// Test behavior, not implementation
+expect(wrapper.vm.isMobile).toBe(false);
+expect(wrapper.find('[data-testid="feature"]').exists()).toBe(false);
+```
+
+## Contributing
+
+When adding new mocks or updating existing ones:
+
+1. **Follow naming conventions**: Use descriptive names with `create` prefix
+2. **Add documentation**: Include JSDoc comments for all functions
+3. **Test all levels**: Ensure all mock levels work correctly
+4. **Update examples**: Add usage examples for new features
+5. **Maintain consistency**: Follow existing patterns and structure
+
+## Security Considerations
+
+- Mocks should not expose sensitive data
+- Use realistic but safe test data
+- Avoid hardcoded credentials or tokens
+- Sanitize any user-provided data in mocks
+
+## Example: ImageViewer Implementation
+
+The `ImageViewer.mock.ts` file demonstrates this pattern in practice:
+
+- **4 mock levels** with increasing complexity
+- **Mock data factories** for realistic test data
+- **Platform detection** for mobile vs desktop testing
+- **Error handling** for share API and image loading failures
+- **Analytics tracking** for performance monitoring
+- **Comprehensive tests** showing all usage patterns
+
+This serves as a template for creating mocks for other components in the project.
