### Registry API

```javascript
const registry = createFactoryRegistry();

registry.get("SF-07");                    // → Factory 元数据
registry.list({ domain: "testing" });      // → 按领域过滤
registry.getDependencies("SF-07");         // → 上游依赖
registry.getDependents("SF-05");          // → 下游依赖者
registry.getTopologicalOrder();           // → 拓扑排序
registry.getParallelBatches();            // → 并行批次

// 注入实现
registry.registerImplementation("SF-07", myFullStackFactory);
registry.execute("SF-07", input);         // → FactoryOutput
```

SF-01 Strategy
  ↓
SF-02 Requirement
  ↓
SF-03 Design ──→ SF-05 Architecture
  ↓                    ↓
SF-04 UI          SF-06 Platform Planning
  ↓                    ↓
  └──────→ SF-07 Development ←──────┘
               ↓
       SF-09 Quality ──→ SF-10 Testing
               ↓               ↓
       └──────→ SF-11 Release ←──────┘

## Artifact Graph

### 图结构

- **节点 (ArtifactNode)**: 产物（代码/文档/测试/报告/…）
- **边 (ArtifactEdge)**: 关系（依赖/产出/派生/包含/…）

### 关系类型（8 种）

```
depends_on / produces / parent_of / derived_from
references / contains / input_to / related_to
```

### 图操作

```javascript
const graph = createArtifactGraph();
graph.addNode(node);
graph.addEdge(edge);

graph.getAncestors(nodeId);        // 追溯依赖祖先
graph.getDescendants(nodeId);      // 追溯下游依赖者
graph.getDependencyChain(nodeId);  // 拓扑排序依赖链
graph.getDirectDependencies(nodeId);
graph.getDirectDependents(nodeId);
graph.validateAll();               // 完整性校验
```

---

## Factory Reporting

| 报告类型 | 内容 |
|----------|------|
| Factory Report | 单 Factory 执行摘要、产物、风险、决策 |
| Project Report | 多 Factory 聚合、风险总结、建议 |
| Product Report | 产品状态、组件、生命周期、质量评估 |
| Release Report | 发布决策、认证、测试结果、制品 |
| Business Report | 产品组合、Factory 舰队、关键指标 |

---

## 使用示例

### 注册并执行 Factory

```javascript
import { createFactoryRegistry, createFactoryInput, createFactoryOutput,
         createFactoryArtifact, createFactoryMetric } from './src/software-factory-core/index.mjs';

const registry = createFactoryRegistry();

// 注入 SF-07 实现
registry.registerImplementation("SF-07", (input) => {
  return createFactoryOutput({
    factoryId: "SF-07",
    status: "passed",
    artifacts: [
      createFactoryArtifact({ kind: "code", name: "auth.ts", factoryId: "SF-07" }),
    ],
    metrics: [
      createFactoryMetric({ factoryId: "SF-07", name: "loc", value: 350, kind: "count", unit: "lines" }),
    ],
    nextActions: ["Run tests"],
  });
});

// 执行
const input = createFactoryInput({ factoryId: "SF-07" });
const output = registry.execute("SF-07", input);
console.log(output.status); // "passed"
```

### 编排 Workflow

```javascript
import { createStandardFactoryWorkflow, executeWorkflow } from './src/software-factory-core/index.mjs';

const wf = createStandardFactoryWorkflow();
const result = await executeWorkflow(wf, registry, { product });
console.log(result.status); // "completed"
```

### 产物追踪

```javascript
import { createArtifactGraph, createArtifactNode, createArtifactEdge } from './src/software-factory-core/index.mjs';

const graph = createArtifactGraph();
const prd = createArtifactNode({ kind: "requirement", name: "PRD v1", factoryId: "SF-02" });
const design = createArtifactNode({ kind: "design", name: "Wireframe", factoryId: "SF-03" });

graph.addNode(prd);
graph.addNode(design);
graph.addEdge(createArtifactEdge({ from: design.id, to: prd.id, relation: "depends_on" }));

const chain = graph.getDependencyChain(design.id);
// → [prd, design] (topological order)
```

---

## 扩展性设计

### 原则

1. **禁止硬编码 Factory 实现** — Registry 只管理元数据，实现通过 `registerImplementation()` 外部注入
2. **保持兼容** — 不修改 `src/agent-runtime/` 任何文件，不修改现有测试
3. **保持可扩展** — `metadata` 字段支持 vendor extensions，自定义 Factory 可在 SF-15 之后添加
4. **纯函数优先** — 数据模型为不可变创建模式，引擎为纯函数

### 未来扩展点

- 在 SF-01~SF-15 之外注册 `SF-16+`
- 实现持久化 Artifact Graph（替换内存 Map）
- 添加 Workflow 可视化（Mermaid/DAG 输出）
- 集成 CI/CD（自动化 Workflow 触发）
