State Management Integration

useAuthStore Integration:

• Retrieves user and permissions
• Stores role information
• Maintains authentication state
• Used by all permission hooks

Zustand Store Access:

const { user, isAuthenticated } = useAuthStore();
// user object contains:
// - id, email, role
// - permissions: string[]
// - roleLevel, tenant info

Security Implementation

Protected Permissions

Admin-only permissions that cannot be granted to non-admin roles:

• roles:manage
• permissions:manage
• tenants:manage
• settings:manage
• audit-logs:manage
• api-keys:manage

Permission Validation

• Wildcard matching prevents overly broad access
• Role hierarchy enforces proper levels
• Backend validation on all requests
• Frontend checks for UX only
• Type-safe permission strings

Audit Trail

• Every permission check can be logged
• Grant/revoke events tracked
• Compliance filtering support
• Export functionality for reports

Performance Characteristics

Caching Strategy

• Default TTL: 5 minutes (configurable)
• Max Cache Size: 500 entries
• Invalidation: Debounced (1 second)
• Memory Safe: Auto-cleanup of old entries

Hook Optimization

• usePermissions: Returns memoized object
• useAuditLog: Static methods
• useCachedPermissionCheck: Memoized function

Batch Operations

• Check multiple permissions efficiently
• Reuse cached results
• Reduce API calls
