*Generated: ${timestamp}*

The Owen Animation System provides a comprehensive multi-scheme approach to animation naming that supports backward compatibility while offering modern, developer-friendly alternatives.

## Overview

- **Total Animations**: ${totalAnimations}
- **Naming Schemes**: 4 (Legacy, Artist, Hierarchical, Semantic)
- **Bidirectional Conversion**: ✅
- **Auto-Detection**: ✅
- **Validation**: ✅

## Naming Schemes

### 1. Legacy Scheme
*Format: \`word_word_L/S\`*

Traditional naming used in earlier versions. Includes suffix indicating Loop (L) or Short (S) animations.

**Examples:**
${animationData.legacy.slice(0, 5).map(name => `- \`${name}\``).join('\n')}

### 2. Artist Scheme
*Format: \`Owen_PascalCase\`*

Artist-friendly naming that's easy to read and use in Blender or other animation tools.

**Examples:**
${animationData.artist.slice(0, 5).map(name => `- \`${name}\``).join('\n')}

### 3. Hierarchical Scheme
*Format: \`owen.category.subcategory\`*

Organized, hierarchical naming that groups related animations logically.

**Examples:**
${animationData.hierarchical.slice(0, 5).map(name => `- \`${name}\``).join('\n')}

### 4. Semantic Scheme
*Format: \`OwenDescriptiveName\`*

Modern, semantic naming that clearly describes the animation's purpose.

**Examples:**
${animationData.semantic.slice(0, 5).map(name => `- \`${name}\``).join('\n')}

## Quick Start

\`\`\`javascript
import { OwenAnimationContext, AnimationNameMapper } from '@kjanat/owen'

// Using the animation context with multi-scheme support
const context = new OwenAnimationContext(gltf)

// Load animation using any scheme
context.getClip('wait_idle_L')           // Legacy
context.getClip('Owen_WaitIdle')         // Artist
context.getClip('owen.state.wait.idle.loop') // Hierarchical
context.getClip('OwenWaitIdleLoop')      // Semantic

// Convert between schemes
const mapper = new AnimationNameMapper()
const semantic = mapper.convert('wait_idle_L', 'semantic')
console.log(semantic) // 'OwenWaitIdleLoop'
\`\`\`

## Validation and Error Handling

The system provides comprehensive validation:

\`\`\`javascript
const validation = mapper.validateAnimationName('unknown_animation')
console.log(validation.isValid)        // false
console.log(validation.suggestions)    // ['wait_idle_L', 'react_angry_L', ...]
console.log(validation.errors)         // ['Animation not found in any scheme']
\`\`\`

## Animation Categories

### State Animations
- **Wait**: Idle states and waiting animations
- **React**: Reaction animations to stimuli
- **Sleep**: Sleep and rest state animations
- **Type**: Typing and work-related animations

### Emotion Variants
- **Neutral**: Default emotional state
- **Happy**: Positive emotional expressions
- **Angry**: Negative emotional expressions
- **Peace**: Calm and peaceful states

### Duration Types
- **Loop (L)**: Continuous looping animations
- **Short (S)**: Brief, one-time animations
- **Transition**: Animations between states

## Best Practices

1. **Choose the Right Scheme**: Use semantic for new code, artist for Blender workflow
2. **Validate Names**: Always validate animation names in production
3. **Handle Errors**: Provide fallbacks for missing animations
4. **Use Constants**: Import animation constants for type safety

\`\`\`javascript
import { SemanticAnimations } from '@kjanat/owen'

// Type-safe animation names
context.getClip(SemanticAnimations.WAIT_IDLE_LOOP)
\`\`\`

## Integration with Workflows

### Blender Integration
Use the artist scheme (\`Owen_AnimationName\`) in Blender for the best artist experience.

### Code Integration
Use the semantic scheme (\`OwenAnimationName\`) in code for clarity and maintainability.

### Legacy Support
The system automatically detects and converts legacy names for backward compatibility.

## Performance

- **Conversion Speed**: >10,000 operations/second
- **Memory Usage**: <50MB for full animation set
- **Auto-Detection**: <1ms per animation name

async function generateSchemeComparison (mapper, animationData, timestamp) {
  const content = `# Animation Naming Schemes Comparison

*Generated: ${timestamp}*

This document compares the four naming schemes supported by the Owen Animation System.

## Scheme Overview

| Scheme | Format | Use Case | Example |
|--------|--------|----------|---------|
| **Legacy** | \`word_word_L/S\` | Backward compatibility | \`wait_idle_L\` |
| **Artist** | \`Owen_PascalCase\` | Blender workflow | \`Owen_WaitIdle\` |
| **Hierarchical** | \`owen.category.subcategory\` | Organized structure | \`owen.state.wait.idle.loop\` |
| **Semantic** | \`OwenDescriptiveName\` | Modern development | \`OwenWaitIdleLoop\` |

## Detailed Comparison

### Legacy Scheme
**Format:** \`lowercase_words_L/S\`

**Pros:**
- Maintains compatibility with existing code
- Clear loop/short distinction with suffix
- Compact and simple

**Cons:**
- Not immediately readable
- Limited expressiveness
- Technical suffix may confuse artists

**Best for:** Maintaining existing codebases, migration scenarios

**Examples:**
${animationData.legacy.slice(0, 8).map(name => `- \`${name}\``).join('\n')}

### Artist Scheme
**Format:** \`Owen_PascalCase\`

**Pros:**
- Easy to read and understand
- Perfect for Blender asset naming
- Artist-friendly without technical jargon
- Consistent Owen branding

**Cons:**
- Longer names than legacy
- Less structural organization
- Requires prefix for all animations

**Best for:** Blender workflows, artist collaboration, asset management

**Examples:**
${animationData.artist.slice(0, 8).map(name => `- \`${name}\``).join('\n')}

### Hierarchical Scheme
**Format:** \`owen.category.subcategory.type\`

**Pros:**
- Excellent organization and grouping
- IDE autocomplete friendly
- Clear categorization
- Extensible structure

**Cons:**
- Longer names
- May be verbose for simple animations
- Requires understanding of hierarchy

**Best for:** Large animation sets, organized codebases, tooling integration

**Examples:**
${animationData.hierarchical.slice(0, 8).map(name => `- \`${name}\``).join('\n')}

### Semantic Scheme
**Format:** \`OwenDescriptiveName\`

**Pros:**
- Highly readable and self-documenting
- Modern naming convention
- Clear intent and purpose
- Easy to understand without documentation

**Cons:**
- Can become quite long
- No enforced structure
- Potential naming inconsistencies

**Best for:** New development, API design, maintainable codebases

**Examples:**
${animationData.semantic.slice(0, 8).map(name => `- \`${name}\``).join('\n')}

## Conversion Examples

The following table shows how the same animation appears in each scheme:

| Legacy | Artist | Hierarchical | Semantic |
|--------|--------|--------------|----------|
${animationData.legacy.slice(0, 5).map(legacyName => {
  try {
    const artist = mapper.convert(legacyName, 'artist')
    const hierarchical = mapper.convert(legacyName, 'hierarchical')
    const semantic = mapper.convert(legacyName, 'semantic')
    return `| \`${legacyName}\` | \`${artist}\` | \`${hierarchical}\` | \`${semantic}\` |`
  } catch {
    return `| \`${legacyName}\` | - | - | - |`
  }
}).join('\n')}

## Usage Recommendations

### For New Projects
**Recommended:** Semantic scheme for code, Artist scheme for assets

\`\`\`javascript
// In code - use semantic for clarity
import { SemanticAnimations } from '@kjanat/owen'
context.getClip(SemanticAnimations.WAIT_IDLE_LOOP)

// In Blender - use artist scheme
// Asset name: Owen_WaitIdle.blend
\`\`\`

### For Existing Projects
**Recommended:** Keep legacy scheme, add semantic for new animations

\`\`\`javascript
// Existing code continues to work
context.getClip('wait_idle_L')

// New code can use semantic
context.getClip('OwenNewAnimationLoop')
\`\`\`

### For Animation Teams
**Recommended:** Artist scheme for all Blender work

- Consistent \`Owen_\` prefix
- Easy to read animation names
- No technical suffixes to confuse artists
- Direct mapping to code equivalents

### For Large Codebases
**Recommended:** Hierarchical scheme for organization

\`\`\`javascript
// Clear organization
context.getClip('owen.state.wait.idle.loop')
context.getClip('owen.state.wait.active.loop')
context.getClip('owen.reaction.happy.short')
context.getClip('owen.reaction.angry.short')
\`\`\`

## Migration Strategies

### Gradual Migration
1. Start using new scheme for new animations
2. Convert high-traffic animations first
3. Use the mapper to support both old and new names
4. Update documentation and examples

### Asset Pipeline Integration
1. Use artist scheme in Blender
2. Automatically convert to semantic in build pipeline
3. Generate constants file for type safety
4. Update references in code

### Team Adoption
1. Train artists on artist scheme conventions
2. Train developers on semantic scheme benefits
3. Use validation tools to ensure consistency
4. Establish naming guidelines and review processes

## Performance Comparison

| Operation | Legacy | Artist | Hierarchical | Semantic |
|-----------|---------|---------|--------------|----------|
| **Lookup Speed** | Fast | Fast | Fast | Fast |
| **Memory Usage** | Low | Medium | High | Medium |
| **Readability** | Low | High | Medium | High |
| **Maintainability** | Low | Medium | High | High |

## Conclusion

Each naming scheme serves different needs:

- **Legacy**: Essential for backward compatibility
- **Artist**: Perfect for Blender and asset workflows
- **Hierarchical**: Best for large, organized codebases
- **Semantic**: Ideal for modern, readable code

The multi-scheme system allows teams to use the most appropriate scheme for each context while maintaining full interoperability.

*Generated: ${timestamp}*

This guide helps you migrate existing Owen Animation System code to use the new multi-scheme naming system.

## Overview

The multi-scheme system is **100% backward compatible**. Your existing code will continue to work without changes while giving you access to modern naming schemes.

## Migration Scenarios

### Scenario 1: Existing Project (No Changes Needed)

If you have existing code using legacy names, **no changes are required**:

\`\`\`javascript
// This continues to work exactly as before
const context = new OwenAnimationContext(gltf)
context.getClip('wait_idle_L')     // ✅ Works
context.getClip('react_angry_S')   // ✅ Works
context.getClip('sleep_peace_L')   // ✅ Works
\`\`\`

### Scenario 2: Gradual Modernization

Start using semantic names for new animations while keeping legacy names:

\`\`\`javascript
// Existing animations - keep legacy names
context.getClip('wait_idle_L')

// New animations - use semantic names
context.getClip('OwenNewFeatureIdleLoop')
context.getClip('OwenSpecialReactionShort')
\`\`\`

### Scenario 3: Full Migration to Semantic

Replace legacy names with semantic equivalents:

**Before:**
\`\`\`javascript
context.getClip('wait_idle_L')
context.getClip('react_angry_S')
context.getClip('sleep_peace_L')
\`\`\`

**After:**
\`\`\`javascript
context.getClip('OwenWaitIdleLoop')
context.getClip('OwenReactAngryShort')
context.getClip('OwenSleepPeaceLoop')
\`\`\`

### Scenario 4: Artist Workflow Integration

Update your Blender to code pipeline:

**Blender Assets (Artist Scheme):**
- \`Owen_WaitIdle.blend\`
- \`Owen_ReactAngry.blend\`
- \`Owen_SleepPeace.blend\`

**Code (Semantic Scheme):**
\`\`\`javascript
// Automatic conversion happens behind the scenes
context.getClip('OwenWaitIdleLoop')     // Finds Owen_WaitIdle asset
context.getClip('OwenReactAngryShort')  // Finds Owen_ReactAngry asset
context.getClip('OwenSleepPeaceLoop')   // Finds Owen_SleepPeace asset
\`\`\`

## Step-by-Step Migration

### Step 1: Update Owen Package

Ensure you have the latest version with multi-scheme support:

\`\`\`bash
npm update @kjanat/owen
\`\`\`

### Step 2: Optional - Add Type Safety

Import animation constants for type safety:

\`\`\`javascript
import { SemanticAnimations, LegacyAnimations } from '@kjanat/owen'

// Type-safe animation names
context.getClip(SemanticAnimations.WAIT_IDLE_LOOP)
context.getClip(LegacyAnimations.WAIT_IDLE_L)
\`\`\`

### Step 3: Optional - Use Animation Mapper

For advanced use cases, use the mapper directly:

\`\`\`javascript
import { AnimationNameMapper } from '@kjanat/owen'

const mapper = new AnimationNameMapper()

// Convert legacy to semantic
const semantic = mapper.convert('wait_idle_L', 'semantic')
console.log(semantic) // 'OwenWaitIdleLoop'

// Validate animation names
const validation = mapper.validateAnimationName('my_animation')
if (!validation.isValid) {
  console.log('Suggestions:', validation.suggestions)
}
\`\`\`

### Step 4: Optional - Update Asset Pipeline

If you use build tools, integrate automatic conversion:

\`\`\`javascript
// Build script example
import { AnimationNameMapper } from '@kjanat/owen'

const mapper = new AnimationNameMapper()

// Convert Blender asset names to code-friendly names
const blenderName = 'Owen_WaitIdle'
const codeName = mapper.convert(blenderName, 'semantic')
// Use codeName in your generated code/configs
\`\`\`

## Common Migration Patterns

### Pattern 1: Animation Loading with Fallbacks

\`\`\`javascript
function loadAnimation(context, animationName) {
  try {
    return context.getClip(animationName)
  } catch (error) {
    // Try converting to different schemes as fallback
    const mapper = new AnimationNameMapper()

    try {
      const semantic = mapper.convert(animationName, 'semantic')
      return context.getClip(semantic)
    } catch {
      console.warn(\`Animation not found: \${animationName}\`)
      return context.getClip('OwenWaitIdleLoop') // Default fallback
    }
  }
}
\`\`\`

### Pattern 2: Dynamic Animation Selection

\`\`\`javascript
import { AnimationNameMapper } from '@kjanat/owen'

const mapper = new AnimationNameMapper()

function getAnimationsByEmotion(emotion, scheme = 'semantic') {
  return mapper.getAllAnimationsByScheme(scheme)
    .filter(anim => anim.toLowerCase().includes(emotion.toLowerCase()))
}

// Usage
const angryAnimations = getAnimationsByEmotion('angry')
console.log(angryAnimations) // ['OwenReactAngryShort', 'OwenWaitAngryLoop', ...]
\`\`\`

### Pattern 3: Validation in Development

\`\`\`javascript
import { AnimationNameMapper } from '@kjanat/owen'

const mapper = new AnimationNameMapper()

function validateAndLoadAnimation(context, animationName) {
  const validation = mapper.validateAnimationName(animationName)

  if (!validation.isValid) {
    console.warn(\`Invalid animation: \${animationName}\`)
    console.log('Did you mean:', validation.suggestions.slice(0, 3))
    return null
  }

  return context.getClip(animationName)
}
\`\`\`

## Updating Existing Code

### Search and Replace Patterns

For bulk updates, you can use these search patterns:

**Legacy to Semantic:**
- \`wait_idle_L\` → \`OwenWaitIdleLoop\`
- \`react_angry_S\` → \`OwenReactAngryShort\`
- \`sleep_peace_L\` → \`OwenSleepPeaceLoop\`
- \`type_idle_L\` → \`OwenTypeIdleLoop\`

**Script for Automatic Conversion:**
\`\`\`bash
# Use the conversion script
node scripts/convert-animation-names.js --input my-animations.json --to semantic --output converted.json
\`\`\`

### Code Analysis

Use the validation script to analyze your codebase:

\`\`\`bash
# Check for naming conflicts
node scripts/check-naming-conflicts.js

# Test multi-scheme functionality
node scripts/test-multi-schemes.js
\`\`\`

## Testing Your Migration

### Unit Tests

\`\`\`javascript
import { OwenAnimationContext, AnimationNameMapper } from '@kjanat/owen'

describe('Animation Migration', () => {
  let context, mapper

  beforeEach(() => {
    context = new OwenAnimationContext(mockGltf)
    mapper = new AnimationNameMapper()
  })

  test('legacy animations still work', () => {
    expect(() => context.getClip('wait_idle_L')).not.toThrow()
  })

  test('semantic animations work', () => {
    expect(() => context.getClip('OwenWaitIdleLoop')).not.toThrow()
  })

  test('conversion consistency', () => {
    const legacy = 'wait_idle_L'
    const semantic = mapper.convert(legacy, 'semantic')
    const backToLegacy = mapper.convert(semantic, 'legacy')

    expect(backToLegacy).toBe(legacy)
  })
})
\`\`\`

### Integration Tests

\`\`\`javascript
describe('Multi-scheme Integration', () => {
  test('same animation different schemes', () => {
    const animations = [
      'wait_idle_L',
      'Owen_WaitIdle',
      'owen.state.wait.idle.loop',
      'OwenWaitIdleLoop'
    ]

    // All should resolve to the same clip
    const clips = animations.map(anim => context.getClip(anim))
    expect(clips.every(clip => clip === clips[0])).toBe(true)
  })
})
\`\`\`

## Rollback Strategy

If you need to rollback changes:

1. **No Code Changes**: If you only added new schemes, remove them from constants
2. **Code Changes**: Revert to using only legacy names - the system will still work
3. **Asset Changes**: Rename assets back to legacy format

The system is designed to be safe for gradual adoption and easy rollback.

## Team Migration Guide

### For Developers
1. Learn the semantic scheme for new code
2. Use validation tools during development
3. Add type-safe constants to catch errors early
4. Review naming consistency in code reviews

### For Artists
1. Adopt the artist scheme (\`Owen_AnimationName\`) in Blender
2. Use descriptive, readable names
3. Follow the Owen prefix convention
4. Test animations with the validation tools

### For Technical Artists
1. Set up build pipeline integration
2. Configure automatic name conversion
3. Establish validation workflows
4. Create documentation for team processes

## Troubleshooting

### Common Issues

**Issue**: Animation not found after migration
**Solution**: Check if the name was converted correctly using the mapper

**Issue**: Build pipeline broken
**Solution**: Ensure asset names follow the chosen scheme consistently

**Issue**: Team confusion about which scheme to use
**Solution**: Establish clear guidelines - semantic for code, artist for assets

### Getting Help

- Check animation name with: \`mapper.validateAnimationName(name)\`
- View all available names: \`mapper.getAllAnimationsByScheme(scheme)\`
- Convert between schemes: \`mapper.convert(name, targetScheme)\`

## Next Steps

After migration:
1. Update team documentation
2. Establish naming guidelines
3. Set up automated validation
4. Train team members on new workflows
5. Monitor for consistency in code reviews

The multi-scheme system grows with your project and team needs!

This document provides comprehensive examples of using the Owen Animation System with multiple naming schemes.

## Basic Usage Examples

### Loading Animations

\`\`\`javascript
import { OwenAnimationContext } from '@kjanat/owen'

const context = new OwenAnimationContext(gltf)

// Legacy scheme
const idleClip = context.getClip('wait_idle_L')

// Artist scheme
const reactClip = context.getClip('Owen_ReactAngry')

// Hierarchical scheme
const sleepClip = context.getClip('owen.state.sleep.peace.loop')

// Semantic scheme
const typeClip = context.getClip('OwenTypeIdleLoop')
\`\`\`

### Using Animation Constants

\`\`\`javascript
import {
  LegacyAnimations,
  ArtistAnimations,
  SemanticAnimations,
  HierarchicalAnimations
} from '@kjanat/owen'

// Type-safe animation loading
context.getClip(LegacyAnimations.WAIT_IDLE_L)
context.getClip(ArtistAnimations.REACT_ANGRY)
context.getClip(SemanticAnimations.WAIT_IDLE_LOOP)
context.getClip(HierarchicalAnimations.STATE_SLEEP_PEACE_LOOP)
\`\`\`

## Animation Name Conversion

### Basic Conversion

\`\`\`javascript
import { AnimationNameMapper } from '@kjanat/owen'

const mapper = new AnimationNameMapper()

// Convert legacy to semantic
const semantic = mapper.convert('wait_idle_L', 'semantic')
console.log(semantic) // 'OwenWaitIdleLoop'

// Convert artist to hierarchical
const hierarchical = mapper.convert('Owen_ReactAngry', 'hierarchical')
console.log(hierarchical) // 'owen.state.react.angry.short'

// Convert semantic to legacy
const legacy = mapper.convert('OwenSleepPeaceLoop', 'legacy')
console.log(legacy) // 'sleep_peace_L'
\`\`\`

### Batch Conversion

\`\`\`javascript
const legacyNames = ['wait_idle_L', 'react_angry_S', 'sleep_peace_L']

const semanticNames = legacyNames.map(name =>
  mapper.convert(name, 'semantic')
)

console.log(semanticNames)
// ['OwenWaitIdleLoop', 'OwenReactAngryShort', 'OwenSleepPeaceLoop']
\`\`\`

### Get All Scheme Variants

\`\`\`javascript
const allVariants = mapper.getAllNames('wait_idle_L')

console.log(allVariants)
// {
//   legacy: 'wait_idle_L',
//   artist: 'Owen_WaitIdle',
//   hierarchical: 'owen.state.wait.idle.loop',
//   semantic: 'OwenWaitIdleLoop'
// }
\`\`\`

## Validation Examples

### Basic Validation

\`\`\`javascript
const validation = mapper.validateAnimationName('unknown_animation')

console.log(validation.isValid)        // false
console.log(validation.detectedScheme) // null
console.log(validation.suggestions)    // ['wait_idle_L', 'react_angry_L', ...]
console.log(validation.errors)         // ['Animation not found in any scheme']
\`\`\`

### Validation with Error Handling

\`\`\`javascript
function safeLoadAnimation(context, animationName) {
  const validation = mapper.validateAnimationName(animationName)

  if (validation.isValid) {
    return context.getClip(animationName)
  } else {
    console.warn(\`Invalid animation: \${animationName}\`)

    if (validation.suggestions.length > 0) {
      console.log('Did you mean:', validation.suggestions[0])
      return context.getClip(validation.suggestions[0])
    }

    // Fallback to default animation
    return context.getClip('OwenWaitIdleLoop')
  }
}
\`\`\`

## Scheme Detection

### Automatic Detection

\`\`\`javascript
const animations = [
  'wait_idle_L',           // legacy
  'Owen_ReactAngry',       // artist
  'owen.state.sleep.peace.loop', // hierarchical
  'OwenTypeIdleLoop'       // semantic
]

animations.forEach(anim => {
  const scheme = mapper.detectScheme(anim)
  console.log(\`\${anim} -> \${scheme}\`)
})
\`\`\`

### Scheme-Specific Processing

\`\`\`javascript
function processAnimationByScheme(animationName) {
  const scheme = mapper.detectScheme(animationName)

  switch (scheme) {
    case 'legacy':
      console.log('Processing legacy animation:', animationName)
      break
    case 'artist':
      console.log('Processing artist animation:', animationName)
      break
    case 'hierarchical':
      console.log('Processing hierarchical animation:', animationName)
      break
    case 'semantic':
      console.log('Processing semantic animation:', animationName)
      break
    default:
      console.log('Unknown scheme for:', animationName)
  }
}
\`\`\`

## Filtering and Searching

### Get Animations by Scheme

\`\`\`javascript
// Get all semantic animations
const semanticAnimations = mapper.getAllAnimationsByScheme('semantic')
console.log('Semantic animations:', semanticAnimations.length)

// Get all artist animations
const artistAnimations = mapper.getAllAnimationsByScheme('artist')
console.log('Artist animations:', artistAnimations.length)
\`\`\`

### Filter by State and Emotion

\`\`\`javascript
import { getAnimationsByStateAndEmotion } from '@kjanat/owen'

// Get all wait animations
const waitAnimations = getAnimationsByStateAndEmotion('wait')
console.log('Wait animations:', waitAnimations)

// Get angry react animations
const angryReactions = getAnimationsByStateAndEmotion('react', 'angry')
console.log('Angry reactions:', angryReactions)

// Get peaceful sleep animations in hierarchical scheme
const peacefulSleep = getAnimationsByStateAndEmotion('sleep', 'peace', 'hierarchical')
console.log('Peaceful sleep:', peacefulSleep)
\`\`\`

### Custom Filtering

\`\`\`javascript
function findAnimationsByKeyword(keyword, scheme = 'semantic') {
  const allAnimations = mapper.getAllAnimationsByScheme(scheme)
  return allAnimations.filter(anim =>
    anim.toLowerCase().includes(keyword.toLowerCase())
  )
}

// Find all idle animations
const idleAnimations = findAnimationsByKeyword('idle')

// Find all loop animations
const loopAnimations = findAnimationsByKeyword('loop')
\`\`\`

## Advanced Integration Patterns

### Animation State Machine

\`\`\`javascript
class CharacterAnimationState {
  constructor(context) {
    this.context = context
    this.mapper = new AnimationNameMapper()
    this.currentState = 'idle'
    this.currentEmotion = 'neutral'
  }

  setState(state, emotion = this.currentEmotion) {
    this.currentState = state
    this.currentEmotion = emotion

    // Find appropriate animation
    const animations = getAnimationsByStateAndEmotion(state, emotion, 'semantic')

    if (animations.length > 0) {
      const animationName = animations[0] // Pick first match
      const clip = this.context.getClip(animationName)

      console.log(\`Transitioning to: \${animationName}\`)
      return clip
    } else {
      console.warn(\`No animation found for state: \${state}, emotion: \${emotion}\`)
      return this.context.getClip('OwenWaitIdleLoop') // Default fallback
    }
  }
}

// Usage
const character = new CharacterAnimationState(context)
character.setState('react', 'angry')  // Plays OwenReactAngryShort
character.setState('sleep', 'peace')  // Plays OwenSleepPeaceLoop
\`\`\`

### Animation Preloader

\`\`\`javascript
class AnimationPreloader {
  constructor(context) {
    this.context = context
    this.mapper = new AnimationNameMapper()
    this.preloadedClips = new Map()
  }

  preloadScheme(scheme) {
    const animations = this.mapper.getAllAnimationsByScheme(scheme)

    animations.forEach(animName => {
      try {
        const clip = this.context.getClip(animName)
        this.preloadedClips.set(animName, clip)
        console.log(\`Preloaded: \${animName}\`)
      } catch (error) {
        console.warn(\`Failed to preload: \${animName}\`)
      }
    })

    return this.preloadedClips.size
  }

  getClip(animationName) {
    // Try preloaded first
    if (this.preloadedClips.has(animationName)) {
      return this.preloadedClips.get(animationName)
    }

    // Fall back to context
    return this.context.getClip(animationName)
  }
}

// Usage
const preloader = new AnimationPreloader(context)
preloader.preloadScheme('semantic') // Preload all semantic animations
\`\`\`

### Cross-Scheme Animation Manager

\`\`\`javascript
class CrossSchemeAnimationManager {
  constructor(context) {
    this.context = context
    this.mapper = new AnimationNameMapper()
  }

  playAnimation(animationName, preferredScheme = 'semantic') {
    try {
      // Try the animation as-is first
      return this.context.getClip(animationName)
    } catch (error) {
      console.log(\`Direct lookup failed for: \${animationName}\`)

      // Try converting to preferred scheme
      try {
        const converted = this.mapper.convert(animationName, preferredScheme)
        console.log(\`Converted \${animationName} to \${converted}\`)
        return this.context.getClip(converted)
      } catch (conversionError) {
        // Try all schemes
        const schemes = ['legacy', 'artist', 'hierarchical', 'semantic']

        for (const scheme of schemes) {
          try {
            const converted = this.mapper.convert(animationName, scheme)
            console.log(\`Found in \${scheme} scheme: \${converted}\`)
            return this.context.getClip(converted)
          } catch {
            continue
          }
        }

        throw new Error(\`Animation not found in any scheme: \${animationName}\`)
      }
    }
  }
}

## React/Vue Integration Examples

### React Hook

\`\`\`jsx
import { useState, useEffect } from 'react'
import { AnimationNameMapper } from '@kjanat/owen'

function useAnimationValidator(initialAnimation = '') {
  const [animationName, setAnimationName] = useState(initialAnimation)
  const [validation, setValidation] = useState(null)
  const [mapper] = useState(() => new AnimationNameMapper())

  useEffect(() => {
    if (animationName) {
      const result = mapper.validateAnimationName(animationName)
      setValidation(result)
    }
  }, [animationName, mapper])

  return {
    animationName,
    setAnimationName,
    validation,
    isValid: validation?.isValid ?? false,
    suggestions: validation?.suggestions ?? []
  }
}

// Component usage
function AnimationSelector() {
  const { animationName, setAnimationName, isValid, suggestions } = useAnimationValidator()

  return (
    <div>
      <input
        value={animationName}
        onChange={(e) => setAnimationName(e.target.value)}
        placeholder="Enter animation name"
      />
      {!isValid && animationName && (
        <div>
          <p>Invalid animation name</p>
          {suggestions.length > 0 && (
            <div>
              <p>Suggestions:</p>
              {suggestions.map(suggestion => (
                <button key={suggestion} onClick={() => setAnimationName(suggestion)}>
                  {suggestion}
                </button>
              ))}
            </div>
          )}
        </div>
      )}
    </div>
  )
