## API Reference

### License Management

#### `initializeLicense(): void`
Initializes the license runtime. Called automatically on first use.

#### `setLicenseTokenFromString(token: string): Promise<void>`
Sets the license token from a string. Validates the token.

#### `requireLicense(): void`
Throws an error if no valid license is available. Called automatically by all Premium ELM variants.

#### `checkLicense(): boolean`
Returns `true` if a valid license is available, `false` otherwise.

#### `getLicenseStatus(): LicenseState`
Returns detailed license status information.

### Common ELM Interface

All Premium ELM variants follow a similar interface:

```typescript
interface ELMConfig {
  categories: string[];
  // ... variant-specific options
}

class PremiumELM {
  constructor(config: ELMConfig);
  train(X: any[], y: number[]): void;
  predict(sample: any, topK?: number): Prediction[];
}
```
