  initialized: 'system:initialized',

  // Parameterized fact constructor
  todoExists: (id: string) => [`todo:${id}`, true] as const,

  // Fact with complex value
  todoStatus: (id: string, status: string) => [`todo:${id}:status`, status] as const,
})

// Usage
facts.todoExists('abc')  // => ['todo:abc', true]
