Key Features at a Glance

1. Enhanced Registry

// Before
registry.register('node-type', executor);

// After
registry.registerWithMetadata('node-type', executor, {
  version: '1.0.0',
  category: 'utility',
  description: '...',
  schema: { ... }
});

2. Intelligent Caching

• Hit rate: 95%+
• Lookup time: <0.1ms
• Auto-eviction of unused entries

3. Multi-Tenant Safety

• 4-layer enforcement
• Audit logging
• Data isolation

4. Error Recovery

• Fallback strategies
• Automatic retries
• Graceful degradation

5. Pre-Execution Validation

• Schema validation
• Dependency checks
• Parameter verification

---

Success Looks Like

After implementation:

• ✓ All plugins registered with metadata
• ✓ Cache hit rate 95%+
• ✓ No multi-tenant data leakage
• ✓ 90%+ test coverage
• ✓ <10ms node execution
• ✓ Zero performance regression
