+
+**The Universal UI Component Specification**
+
+*The foundational protocol for the ObjectStack ecosystem*
+
+---
+
+## Overview
+
+`@objectstack/spec` (v0.1.1) defines the **highest law** - the core interfaces and types that all UI components in the ObjectStack ecosystem must follow. This package provides the universal protocol that enables schema-driven UI rendering across different frameworks and implementations.
+
+## Key Concepts
+
+### UIComponent - The Foundation
+
+Every UI component in the ObjectStack ecosystem extends from `UIComponent`:
+
+```typescript
+interface UIComponent {
+  type: string;           // Component type discriminator
+  id?: string;            // Unique identifier
+  props?: Record<string, any>;  // Component-specific properties
+  children?: SchemaNode | SchemaNode[];  // Child content
+  [key: string]: any;     // Extensibility
+}
+```
+
+### The Inheritance Chain
+
+```
+UIComponent (@objectstack/spec)          ← The highest law
+    ↓
+BaseSchema (@object-ui/types)            ← ObjectUI extensions
+    ↓
+Specific Schemas (ChartSchema, etc.)     ← Component implementations
+```
+
+## Installation
+
+```bash
+npm install @objectstack/spec
+# or
+yarn add @objectstack/spec
+# or
+pnpm add @objectstack/spec
+```
+
+## Usage
+
+### Type Definitions
+
+```typescript
+import type { UIComponent, SchemaNode, ComponentType } from '@objectstack/spec';
+
+// Define a component
+const button: UIComponent = {
+  type: 'button',
+  id: 'submit-btn',
+  props: {
+    label: 'Submit',
+    variant: 'primary',
+    onClick: () => console.log('clicked')
+  }
+};
+
+// Compose components
+const form: UIComponent = {
+  type: 'form',
+  id: 'user-form',
+  children: [
+    { type: 'input', props: { name: 'email', label: 'Email' } },
+    { type: 'input', props: { name: 'password', label: 'Password' } },
+    button
+  ]
+};
+```
+
+### Extending UIComponent
+
+```typescript
+import type { UIComponent } from '@objectstack/spec';
+
+// Create your own schema
+interface CustomButtonSchema extends UIComponent {
+  type: 'custom-button';
+  props?: {
+    label?: string;
+    variant?: 'primary' | 'secondary';
+    size?: 'sm' | 'md' | 'lg';
+  };
+}
+
+const myButton: CustomButtonSchema = {
+  type: 'custom-button',
+  props: {
+    label: 'Click Me',
+    variant: 'primary',
+    size: 'lg'
+  }
+};
+```
+
+## Design Principles
+
+### 1. Type as Discriminator
+
+The `type` field is the **discriminator** that determines which component to render:
+
+```typescript
+function resolveComponent(schema: UIComponent) {
+  switch (schema.type) {
+    case 'button': return ButtonComponent;
+    case 'input': return InputComponent;
+    case 'chart': return ChartComponent;
+    default: return FallbackComponent;
+  }
+}
+```
+
+### 2. Props-Based Configuration
+
+All component-specific properties go in the `props` object:
+
+```typescript
+{
+  type: 'chart',
+  props: {
+    chartType: 'bar',
+    series: [...],
+    showLegend: true
+  }
+}
+```
+
+### 3. Composability via Children
+
+Components can nest indefinitely:
+
+```typescript
+{
+  type: 'card',
+  children: [
+    { type: 'heading', props: { text: 'Title' } },
+    { type: 'text', props: { value: 'Content' } },
+    { type: 'button', props: { label: 'Action' } }
+  ]
+}
+```
+
+### 4. Framework Agnostic
+
+The spec is pure TypeScript with **zero dependencies**:
+- ✅ Works with React, Vue, Angular, Svelte
+- ✅ No runtime overhead
+- ✅ Complete type safety
+- ✅ Serializable to JSON
+
+## Core Types
+
+### UIComponent
+
+The base interface for all UI components.
+
+### SchemaNode
+
+Union type for component tree nodes:
+```typescript
+type SchemaNode = UIComponent | string | number | boolean | null | undefined;
+```
+
+### ComponentType
+
+Type alias for component type identifiers:
+```typescript
+type ComponentType = string;
+```
+
+### ActionSchema
+
+Interface for event actions:
+```typescript
+interface ActionSchema {
+  action: string;
+  target?: string;
+  params?: Record<string, any>;
+  condition?: string;
+}
+```
+
+### ComponentMetadata
+
+Metadata for designer/editor integration:
+```typescript
+interface ComponentMetadata {
+  label?: string;
+  icon?: string;
+  category?: string;
+  description?: string;
+  tags?: string[];
+  isContainer?: boolean;
+  examples?: Record<string, UIComponent>;
+}
+```
+
+## Compliance Rules
+
+When implementing components for the ObjectStack ecosystem:
+
+1. ✅ **MUST** extend from `UIComponent` (directly or indirectly)
+2. ✅ **MUST** include a `type` field (the discriminator)
+3. ✅ **MUST** place component-specific props in the `props` object
+4. ✅ **SHOULD** support `children` for composable components
+5. ✅ **SHOULD** support `id` for unique identification
+
+## Examples
+
+### Simple Component
+
+```typescript
+const text: UIComponent = {
+  type: 'text',
+  props: {
+    value: 'Hello World',
+    className: 'text-lg font-bold'
+  }
+};
+```
+
+### Container Component
+
+```typescript
+const grid: UIComponent = {
+  type: 'grid',
+  props: {
+    columns: 3,
+    gap: 4
+  },
+  children: [
+    { type: 'card', props: { title: 'Card 1' } },
+    { type: 'card', props: { title: 'Card 2' } },
+    { type: 'card', props: { title: 'Card 3' } }
+  ]
+};
+```
+
+### With Actions
+
+```typescript
+const button: UIComponent = {
+  type: 'button',
+  props: {
+    label: 'Submit',
+    events: {
+      onClick: [
+        { action: 'validate', target: 'form-1' },
+        { action: 'submit', target: 'form-1' }
+      ]
+    }
+  }
+};
+```
+
+## Version History

+
+Initial release with core interfaces:
+- `UIComponent` - Base component interface
+- `SchemaNode` - Union type for tree nodes
+- `ActionSchema` - Event action definition
+- `ComponentMetadata` - Designer metadata

+## Philosophy
+
+> **"Protocol First, Implementation Later"**
+
+By defining a universal specification first, we enable:
+- 🔄 Multiple UI implementations (Shadcn, Material, Ant Design)
+- 🔄 Multiple frameworks (React, Vue, Svelte, Angular)
+- 🔄 Multiple backends (REST, GraphQL, ObjectQL)
+- 🔄 Static analysis without runtime dependencies

+# Architecture: ObjectStack Spec Integration
+
+## Overview
+
+This document explains how ObjectUI integrates with `@objectstack/spec` (v0.1.1) as the foundational protocol for all UI components.
+
+## The Inheritance Chain
+
+```
+@objectstack/spec (v0.1.1)          ← The "Highest Law" - Universal Protocol
+    ↓
+UIComponent                         ← Base interface for all UI components
+    ↓
+BaseSchema (@object-ui/types)       ← ObjectUI-specific extensions
+    ↓
+Specific Schemas                    ← Component implementations
+    ↓
+Component Renderers                 ← UI implementations
+```
+
+### 1. UIComponent (@objectstack/spec)
+
+The foundational interface that defines the core protocol for schema-driven UI:
+
+```typescript
+interface UIComponent {
+  type: string;                           // Component type discriminator
+  id?: string;                            // Unique identifier
+  props?: Record<string, any>;            // Component-specific properties
+  children?: SchemaNode | SchemaNode[];   // Child content
+  [key: string]: any;                     // Extensibility
+}
+```
+
+**Why this is the "highest law":**
+- Defines the universal contract for all UI components
+- Ensures interoperability across the ObjectStack ecosystem
+- Provides the type discriminator pattern
+- Enables JSON serialization
+
+### 2. BaseSchema (@object-ui/types)
+
+Extends `UIComponent` with ObjectUI-specific rendering logic:
+
+```typescript
+interface BaseSchema extends UIComponent {
+  // Inherited from UIComponent
+  type: string;
+  id?: string;
+  children?: SchemaNode | SchemaNode[];
+  
+  // ObjectUI extensions
+  className?: string;          // Tailwind CSS classes
+  visible?: boolean;           // Static visibility
+  visibleOn?: string;          // Dynamic visibility (expression)
+  hidden?: boolean;            // Static hiding
+  hiddenOn?: string;           // Dynamic hiding (expression)
+  disabled?: boolean;          // Static disabled state
+  disabledOn?: string;         // Dynamic disabled state (expression)
+  
+  // Additional ObjectUI properties
+  name?: string;
+  label?: string;
+  description?: string;
+  placeholder?: string;
+  style?: Record<string, string | number>;
+  data?: any;
+  body?: SchemaNode | SchemaNode[];
+  testId?: string;
+  ariaLabel?: string;
+}
+```
+
+### 3. Specific Schemas (e.g., ChartSchema)
+
+Component-specific interfaces that extend `BaseSchema`:
+
+```typescript
+interface ChartSchema extends BaseSchema {
+  type: 'chart';                    // Type discriminator
+  chartType: ChartType;             // Chart-specific property
+  title?: string;
+  description?: string;
+  categories?: string[];
+  series: ChartSeries[];
+  height?: string | number;
+  showLegend?: boolean;
+  showGrid?: boolean;
+  animate?: boolean;
+  config?: Record<string, any>;
+}
+```
+
+## Data Display Components
+
+The following components are defined in `@object-ui/types/data-display`:
+
+| Type | Component | Schema Interface | Key Properties |
+|------|-----------|-----------------|----------------|
+| `alert` | Alert | `AlertSchema` | title, description, variant, icon, dismissible |
+| `statistic` | Metric Card | `StatisticSchema` | label, value, trend, description, icon |
+| `badge` | Badge | `BadgeSchema` | label, variant, icon |
+| `avatar` | Avatar | `AvatarSchema` | src, alt, fallback, size, shape |
+| `list` | List | `ListSchema` | items, ordered, dividers |
+| `table` | Basic Table | `TableSchema` | columns, data, caption, hoverable |
+| `data-table` | Data Grid | `DataTableSchema` | pagination, searchable, rowActions, selectable |
+| `chart` | Chart | `ChartSchema` | chartType, series, categories, showLegend |
+| `timeline` | Timeline | `TimelineSchema` | events, orientation, position |
+| `tree-view` | Tree View | `TreeViewSchema` | data, multiSelect, showLines |
+| `markdown` | Markdown | `MarkdownSchema` | content, sanitize |
+| `html` | Raw HTML | `HtmlSchema` | html |
+
+## Usage Examples
+
+### 1. Simple Component (Compliant with UIComponent)
+
+```json
+{
+  "type": "badge",
+  "id": "status-badge",
+  "props": {
+    "label": "New",
+    "variant": "default"
+  }
+}
+```
+
+### 2. Component with ObjectUI Extensions
+
+```json
+{
+  "type": "alert",
+  "id": "welcome-alert",
+  "title": "Welcome!",
+  "description": "Thank you for using ObjectUI",
+  "variant": "default",
+  "icon": "info",
+  "dismissible": true,
+  "visibleOn": "${user.isNewUser}",
+  "className": "mb-4"
+}
+```
+
+### 3. Complex Component with Children
+
+```json
+{
+  "type": "flex",
+  "id": "user-profile",
+  "props": {
+    "direction": "col",
+    "gap": 4
+  },
+  "children": [
+    {
+      "type": "avatar",
+      "src": "https://github.com/shadcn.png",
+      "fallback": "JD",
+      "size": "lg"
+    },
+    {
+      "type": "statistic",
+      "label": "Followers",
+      "value": "1,234",
+      "trend": "up"
+    },
+    {
+      "type": "badge",
+      "label": "Pro Member",
+      "variant": "default"
+    }
+  ]
+}
+```
+
+### 4. Data Display with Chart
+
+```json
+{
+  "type": "chart",
+  "id": "sales-chart",
+  "chartType": "bar",
+  "title": "Monthly Sales",
+  "categories": ["Jan", "Feb", "Mar", "Apr", "May", "Jun"],
+  "series": [
+    {
+      "name": "Revenue",
+      "data": [12000, 15000, 18000, 14000, 22000, 25000],
+      "color": "#3b82f6"
+    }
+  ],
+  "showLegend": true,
+  "height": 400
+}
+```
+
+## Protocol Compliance Rules
+
+When creating or using components:
+
+1. ✅ **MUST** extend from `UIComponent` (directly or indirectly via `BaseSchema`)
+2. ✅ **MUST** include a `type` field (the discriminator)
+3. ✅ **MUST** use the correct type value from the component registry
+4. ✅ **SHOULD** place component-specific properties at the top level (not in props)
+5. ✅ **SHOULD** use `props` for standard HTML attributes (role, aria-*, data-*)
+6. ✅ **SHOULD** support `children` for composable components
+7. ✅ **SHOULD** support `id` for unique identification
+8. ✅ **MAY** use ObjectUI extensions (className, visibleOn, etc.)

+# ObjectStack Spec Integration - Implementation Summary
+
+## 任务概述 (Task Overview)
+
+这个 PR 实现了将 `@objectstack/spec` (v0.1.1) 作为 ObjectUI 类型系统的"最高法律"的需求。
+
+This PR implements the integration of `@objectstack/spec` (v0.1.1) as the "highest law" for the ObjectUI type system.
+
+## 完成的工作 (Completed Work)
+
+### 1. 创建 `@objectstack/spec` 包 (Created @objectstack/spec Package)
+
+**位置 (Location)**: `packages/objectstack-spec/`
+
+**核心接口 (Core Interface)**:
+```typescript
+interface UIComponent {
+  type: string;                           // 组件类型识别器 (Component type discriminator)
+  id?: string;                            // 唯一标识符 (Unique identifier)
+  props?: Record<string, any>;            // 组件属性 (Component properties)
+  children?: SchemaNode | SchemaNode[];   // 子内容 (Child content)
+  [key: string]: any;                     // 可扩展性 (Extensibility)
+}
+```
+
+**特性 (Features)**:
+- ✅ 零依赖 (Zero dependencies)
+- ✅ 纯 TypeScript 类型定义 (Pure TypeScript types)
+- ✅ 完整的 JSDoc 文档 (Complete JSDoc documentation)
+- ✅ 支持类型检查 (Type checking support)
+
+### 2. 更新 `@object-ui/types` 继承自 Spec (Updated @object-ui/types to Extend from Spec)
+
+**继承链 (Inheritance Chain)**:
+```
+UIComponent (@objectstack/spec)          ← 最高法律 (The Highest Law)
+    ↓
+BaseSchema (@object-ui/types)            ← ObjectUI 扩展 (ObjectUI Extensions)
+    ↓
+具体 Schema (ChartSchema, etc.)          ← 组件实现 (Component Implementations)
+```
+
+**ObjectUI 扩展 (ObjectUI Extensions)**:
+- `visibleOn` - 动态可见性表达式 (Dynamic visibility expressions)
+- `hiddenOn` - 动态隐藏表达式 (Dynamic hiding expressions)
+- `disabledOn` - 动态禁用表达式 (Dynamic disabled expressions)
+- `className` - Tailwind CSS 类 (Tailwind CSS classes)
+- 其他渲染层逻辑 (Other rendering logic)
+
+### 3. 验证数据显示组件合规性 (Validated Data Display Components Compliance)
+
+**已验证的组件 (Verified Components)** (12个):
+
+| 类型 (Type) | 组件 (Component) | Schema 接口 (Schema Interface) |
+|-------------|------------------|--------------------------------|
+| `alert` | Alert | `AlertSchema` |
+| `statistic` | Metric Card | `StatisticSchema` |
+| `badge` | Badge | `BadgeSchema` |
+| `avatar` | Avatar | `AvatarSchema` |
+| `list` | List | `ListSchema` |
+| `table` | Basic Table | `TableSchema` |
+| `data-table` | Data Grid | `DataTableSchema` |
+| `chart` | Chart | `ChartSchema` |
+| `timeline` | Timeline | `TimelineSchema` |
+| `tree-view` | Tree View | `TreeViewSchema` |
+| `markdown` | Markdown | `MarkdownSchema` |
+| `html` | Raw HTML | `HtmlSchema` |
+
+**所有组件都遵循协议 (All components follow the protocol)**:
+- ✅ 正确的 `type` 识别器 (Correct `type` discriminator)
+- ✅ 继承自 `BaseSchema` (Extend from `BaseSchema`)
+- ✅ 可 JSON 序列化 (JSON serializable)
+
+### 4. 创建示例和文档 (Created Examples and Documentation)
+
+**JSON 示例 (JSON Examples)**:
+- `packages/types/examples/data-display-examples.json`
+- 包含所有 12 个数据显示组件的完整示例 (Complete examples for all 12 data display components)
+- 展示了如何正确使用协议 (Demonstrates correct protocol usage)
+
+**架构文档 (Architecture Documentation)**:
+- `docs/architecture/objectstack-spec-integration.md`
+- 详细解释继承链 (Detailed explanation of inheritance chain)
+- 使用示例 (Usage examples)
+- 合规规则 (Compliance rules)
+
+**包 README 更新 (Package README Updates)**:
+- `packages/objectstack-spec/README.md` - 新建 (New)
+- `packages/types/README.md` - 更新以反映新架构 (Updated to reflect new architecture)
+
+## 技术细节 (Technical Details)
+
+### 类型安全 (Type Safety)
+
+```typescript
+import type { ChartSchema } from '@object-ui/types/data-display';
+import type { UIComponent } from '@objectstack/spec';
+
+// 所有 Schema 都可以赋值给 UIComponent (All schemas are assignable to UIComponent)
+const chart: ChartSchema = {
+  type: 'chart',
+  chartType: 'bar',
+  series: [{ name: 'Sales', data: [100, 200] }]
+};
+
+const component: UIComponent = chart;  // ✅ 有效 (Valid)
+```
+
+### 表达式支持 (Expression Support)
+
+ObjectUI 扩展了 spec，支持动态行为表达式 (ObjectUI extends the spec with expression support for dynamic behavior):
+
+```json
+{
+  "type": "badge",
+  "label": "Admin",
+  "visibleOn": "${user.role === 'admin'}"
+}
+```
+
+## 测试结果 (Testing Results)

-
-**The Universal UI Component Specification**
-
-*The foundational protocol for the ObjectStack ecosystem*
-
----
-
-## Overview
-
-`@objectstack/spec` (v0.1.1) defines the **highest law** - the core interfaces and types that all UI components in the ObjectStack ecosystem must follow. This package provides the universal protocol that enables schema-driven UI rendering across different frameworks and implementations.
-
-## Key Concepts
-
-### UIComponent - The Foundation
-
-Every UI component in the ObjectStack ecosystem extends from `UIComponent`:
-
-```typescript
-interface UIComponent {
-  type: string;           // Component type discriminator
-  id?: string;            // Unique identifier
-  props?: Record<string, any>;  // Component-specific properties
-  children?: SchemaNode | SchemaNode[];  // Child content
-  [key: string]: any;     // Extensibility
-}
-```
-
-### The Inheritance Chain
-
-```
-UIComponent (@objectstack/spec)          ← The highest law
-    ↓
-BaseSchema (@object-ui/types)            ← ObjectUI extensions
-    ↓
-Specific Schemas (ChartSchema, etc.)     ← Component implementations
-```
-
-## Installation
-
-```bash
-npm install @objectstack/spec
-# or
-yarn add @objectstack/spec
-# or
-pnpm add @objectstack/spec
-```
-
-## Usage
-
-### Type Definitions
-
-```typescript
-import type { UIComponent, SchemaNode, ComponentType } from '@objectstack/spec';
-
-// Define a component
-const button: UIComponent = {
-  type: 'button',
-  id: 'submit-btn',
-  props: {
-    label: 'Submit',
-    variant: 'primary',
-    onClick: () => console.log('clicked')
-  }
-};
-
-// Compose components
-const form: UIComponent = {
-  type: 'form',
-  id: 'user-form',
-  children: [
-    { type: 'input', props: { name: 'email', label: 'Email' } },
-    { type: 'input', props: { name: 'password', label: 'Password' } },
-    button
-  ]
-};
-```
-
-### Extending UIComponent
-
-```typescript
-import type { UIComponent } from '@objectstack/spec';
-
-// Create your own schema
-interface CustomButtonSchema extends UIComponent {
-  type: 'custom-button';
-  props?: {
-    label?: string;
-    variant?: 'primary' | 'secondary';
-    size?: 'sm' | 'md' | 'lg';
-  };
-}
-
-const myButton: CustomButtonSchema = {
-  type: 'custom-button',
-  props: {
-    label: 'Click Me',
-    variant: 'primary',
-    size: 'lg'
-  }
-};
-```
-
-## Design Principles
-
-### 1. Type as Discriminator
-
-The `type` field is the **discriminator** that determines which component to render:
-
-```typescript
-function resolveComponent(schema: UIComponent) {
-  switch (schema.type) {
-    case 'button': return ButtonComponent;
-    case 'input': return InputComponent;
-    case 'chart': return ChartComponent;
-    default: return FallbackComponent;
-  }
-}
-```
-
-### 2. Props-Based Configuration
-
-All component-specific properties go in the `props` object:
-
-```typescript
-{
-  type: 'chart',
-  props: {
-    chartType: 'bar',
-    series: [...],
-    showLegend: true
-  }
-}
-```
-
-### 3. Composability via Children
-
-Components can nest indefinitely:
-
-```typescript
-{
-  type: 'card',
-  children: [
-    { type: 'heading', props: { text: 'Title' } },
-    { type: 'text', props: { value: 'Content' } },
-    { type: 'button', props: { label: 'Action' } }
-  ]
-}
-```
-
-### 4. Framework Agnostic
-
-The spec is pure TypeScript with **zero dependencies**:
-- ✅ Works with React, Vue, Angular, Svelte
-- ✅ No runtime overhead
-- ✅ Complete type safety
-- ✅ Serializable to JSON
-
-## Core Types
-
-### UIComponent
-
-The base interface for all UI components.
-
-### SchemaNode
-
-Union type for component tree nodes:
-```typescript
-type SchemaNode = UIComponent | string | number | boolean | null | undefined;
-```
-
-### ComponentType
-
-Type alias for component type identifiers:
-```typescript
-type ComponentType = string;
-```
-
-### ActionSchema
-
-Interface for event actions:
-```typescript
-interface ActionSchema {
-  action: string;
-  target?: string;
-  params?: Record<string, any>;
-  condition?: string;
-}
-```
-
-### ComponentMetadata
-
-Metadata for designer/editor integration:
-```typescript
-interface ComponentMetadata {
-  label?: string;
-  icon?: string;
-  category?: string;
-  description?: string;
-  tags?: string[];
-  isContainer?: boolean;
-  examples?: Record<string, UIComponent>;
-}
-```
-
-## Compliance Rules
-
-When implementing components for the ObjectStack ecosystem:
-
-1. ✅ **MUST** extend from `UIComponent` (directly or indirectly)
-2. ✅ **MUST** include a `type` field (the discriminator)
-3. ✅ **MUST** place component-specific props in the `props` object
-4. ✅ **SHOULD** support `children` for composable components
-5. ✅ **SHOULD** support `id` for unique identification
-
-## Examples
-
-### Simple Component
-
-```typescript
-const text: UIComponent = {
-  type: 'text',
-  props: {
-    value: 'Hello World',
-    className: 'text-lg font-bold'
-  }
-};
-```
-
-### Container Component
-
-```typescript
-const grid: UIComponent = {
-  type: 'grid',
-  props: {
-    columns: 3,
-    gap: 4
-  },
-  children: [
-    { type: 'card', props: { title: 'Card 1' } },
-    { type: 'card', props: { title: 'Card 2' } },
-    { type: 'card', props: { title: 'Card 3' } }
-  ]
-};
-```
-
-### With Actions
-
-```typescript
-const button: UIComponent = {
-  type: 'button',
-  props: {
-    label: 'Submit',
-    events: {
-      onClick: [
-        { action: 'validate', target: 'form-1' },
-        { action: 'submit', target: 'form-1' }
-      ]
-    }
-  }
-};
-```
-
-## Version History
-
-### v0.1.1 (Current)
-
-Initial release with core interfaces:
-- `UIComponent` - Base component interface
-- `SchemaNode` - Union type for tree nodes
-- `ActionSchema` - Event action definition
-- `ComponentMetadata` - Designer metadata

-## Philosophy
-
-> **"Protocol First, Implementation Later"**
-
-By defining a universal specification first, we enable:
-- 🔄 Multiple UI implementations (Shadcn, Material, Ant Design)
-- 🔄 Multiple frameworks (React, Vue, Svelte, Angular)
-- 🔄 Multiple backends (REST, GraphQL, ObjectQL)
-- 🔄 Static analysis without runtime dependencies

-# ObjectStack Spec Integration - Implementation Summary
-
-## 任务概述 (Task Overview)
-
-这个 PR 实现了将 `@objectstack/spec` (v0.1.1) 作为 ObjectUI 类型系统的"最高法律"的需求。
-
-This PR implements the integration of `@objectstack/spec` (v0.1.1) as the "highest law" for the ObjectUI type system.
-
-## 完成的工作 (Completed Work)
-
-### 1. 创建 `@objectstack/spec` 包 (Created @objectstack/spec Package)
-
-**位置 (Location)**: `packages/objectstack-spec/`
-
-**核心接口 (Core Interface)**:
-```typescript
-interface UIComponent {
-  type: string;                           // 组件类型识别器 (Component type discriminator)
-  id?: string;                            // 唯一标识符 (Unique identifier)
-  props?: Record<string, any>;            // 组件属性 (Component properties)
-  children?: SchemaNode | SchemaNode[];   // 子内容 (Child content)
-  [key: string]: any;                     // 可扩展性 (Extensibility)
-}
-```
-
-**特性 (Features)**:
-- ✅ 零依赖 (Zero dependencies)
-- ✅ 纯 TypeScript 类型定义 (Pure TypeScript types)
-- ✅ 完整的 JSDoc 文档 (Complete JSDoc documentation)
-- ✅ 支持类型检查 (Type checking support)
-
-### 2. 更新 `@object-ui/types` 继承自 Spec (Updated @object-ui/types to Extend from Spec)
-
-**继承链 (Inheritance Chain)**:
-```
-UIComponent (@objectstack/spec)          ← 最高法律 (The Highest Law)
-    ↓
-BaseSchema (@object-ui/types)            ← ObjectUI 扩展 (ObjectUI Extensions)
-    ↓
-具体 Schema (ChartSchema, etc.)          ← 组件实现 (Component Implementations)
-```
-
-**ObjectUI 扩展 (ObjectUI Extensions)**:
-- `visibleOn` - 动态可见性表达式 (Dynamic visibility expressions)
-- `hiddenOn` - 动态隐藏表达式 (Dynamic hiding expressions)
-- `disabledOn` - 动态禁用表达式 (Dynamic disabled expressions)
-- `className` - Tailwind CSS 类 (Tailwind CSS classes)
-- 其他渲染层逻辑 (Other rendering logic)
-
-### 3. 验证数据显示组件合规性 (Validated Data Display Components Compliance)
-
-**已验证的组件 (Verified Components)** (12个):
-
-| 类型 (Type) | 组件 (Component) | Schema 接口 (Schema Interface) |
-|-------------|------------------|--------------------------------|
-| `alert` | Alert | `AlertSchema` |
-| `statistic` | Metric Card | `StatisticSchema` |
-| `badge` | Badge | `BadgeSchema` |
-| `avatar` | Avatar | `AvatarSchema` |
-| `list` | List | `ListSchema` |
-| `table` | Basic Table | `TableSchema` |
-| `data-table` | Data Grid | `DataTableSchema` |
-| `chart` | Chart | `ChartSchema` |
-| `timeline` | Timeline | `TimelineSchema` |
-| `tree-view` | Tree View | `TreeViewSchema` |
-| `markdown` | Markdown | `MarkdownSchema` |
-| `html` | Raw HTML | `HtmlSchema` |
-
-**所有组件都遵循协议 (All components follow the protocol)**:
-- ✅ 正确的 `type` 识别器 (Correct `type` discriminator)
-- ✅ 继承自 `BaseSchema` (Extend from `BaseSchema`)
-- ✅ 可 JSON 序列化 (JSON serializable)
-
-### 4. 创建示例和文档 (Created Examples and Documentation)
-
-**JSON 示例 (JSON Examples)**:
-- `packages/types/examples/data-display-examples.json`
-- 包含所有 12 个数据显示组件的完整示例 (Complete examples for all 12 data display components)
-- 展示了如何正确使用协议 (Demonstrates correct protocol usage)
-
-**架构文档 (Architecture Documentation)**:
-- `docs/architecture/objectstack-spec-integration.md`
-- 详细解释继承链 (Detailed explanation of inheritance chain)
-- 使用示例 (Usage examples)
-- 合规规则 (Compliance rules)
-
-**包 README 更新 (Package README Updates)**:
-- `packages/objectstack-spec/README.md` - 新建 (New)
-- `packages/types/README.md` - 更新以反映新架构 (Updated to reflect new architecture)
-
-## 技术细节 (Technical Details)
-
-### 类型安全 (Type Safety)
-
-```typescript
-import type { ChartSchema } from '@object-ui/types/data-display';
-import type { UIComponent } from '@objectstack/spec';
-
-// 所有 Schema 都可以赋值给 UIComponent (All schemas are assignable to UIComponent)
-const chart: ChartSchema = {
-  type: 'chart',
-  chartType: 'bar',
-  series: [{ name: 'Sales', data: [100, 200] }]
-};
-
-const component: UIComponent = chart;  // ✅ 有效 (Valid)
-```
-
-### 表达式支持 (Expression Support)
-
-ObjectUI 扩展了 spec，支持动态行为表达式 (ObjectUI extends the spec with expression support for dynamic behavior):
-
-```json
-{
-  "type": "badge",
-  "label": "Admin",
-  "visibleOn": "${user.role === 'admin'}"
-}
-```
-

-3. ✅ **必须 (MUST)** 使用正确的 type 值
-4. ✅ **应该 (SHOULD)** 将组件特定属性放在顶层
-5. ✅ **应该 (SHOULD)** 在 `props` 中放置标准 HTML 属性
-6. ✅ **应该 (SHOULD)** 支持 `children` 用于可组合组件
-7. ✅ **应该 (SHOULD)** 支持 `id` 用于唯一标识
-8. ✅ **可以 (MAY)** 使用 ObjectUI 扩展（className, visibleOn 等）
-
-## 代码审查反馈 (Code Review Feedback)
-
-已解决的问题 (Resolved Issues):
-1. ✅ 移除了未使用的 `SpecSchemaNode` 导入别名 (Removed unused import alias)
-2. ✅ 移除了冗余的 `type` 字段声明 (Removed redundant type field declaration)
-3. ✅ 添加了 SchemaNode 类型差异的文档说明 (Documented SchemaNode type divergence)
-

Subject: [PATCH 14/14] Fix CI lockfile error by removing @objectstack/spec
 dependency

The pnpm-lock.yaml was out of sync with packages/types/package.json.
The @objectstack/spec npm package (v0.1.1) doesn't export UIComponent interface,
so reverting to the original BaseSchema definition without external dependencies.
