# Advanced Plugin Lifecycle Protocol

Defines advanced lifecycle management capabilities including:

- Hot reload and live updates

- Graceful degradation and fallback mechanisms

- Health monitoring and auto-recovery

- State preservation during updates

This protocol extends the basic plugin lifecycle with enterprise-grade

features for production environments.

## TypeScript Usage

```typescript
import { AdvancedPluginLifecycleConfig, DistributedStateConfig, GracefulDegradation, HotReloadConfig, PluginHealthCheck, PluginHealthReport, PluginHealthStatus, PluginStateSnapshot, PluginUpdateStrategy } from '@objectstack/spec/kernel';
import type { AdvancedPluginLifecycleConfig, DistributedStateConfig, GracefulDegradation, HotReloadConfig, PluginHealthCheck, PluginHealthReport, PluginHealthStatus, PluginStateSnapshot, PluginUpdateStrategy } from '@objectstack/spec/kernel';

// Validate data
const result = AdvancedPluginLifecycleConfig.parse(data);
```
