+# D7a intent 与 bizdev 解绑
+
+## 目标
+
+intent 只依赖成熟度词汇叶子包，不再 import bizdev。
+
+## 范围
+
+- `internal/maturity`
+- intent 生产与表征测试
+- bizdev 类型别名保持兼容
+
+## 非目标
+
+- 不改识别规则
+- 不迁 coordinator / chatflow（D5/D7b）
+
+## 步骤
+
+1. [x] 叶子包与别名
+2. [x] intent 切断 bizdev
+3. [x] 表征测试与 arch-check
+4. [x] 报告
+
+## 验收标准
+
+- [x] intent 生产 import 无 bizdev
+- [x] [S4a 报告](../../test-reports/2026-09-15-intent-bizdev-boundary-test-report.md)

+# D7a intent 与 bizdev 解绑测试报告
+
+## 一、 测试背景 (Background)
+
+intent 只为读取三档成熟度常量而 import 整个 bizdev，把识别层绑在编排根上。D7a 把常量抽到叶子包 `internal/maturity`。
+
+## 二、 测试目标 (Test Objectives)
+
+- 阶段 token 不变：`V0.1_triage` / `V0.5_feasibility` / `V1.0_quoting`。
+- intent 生产代码与测试不再 import bizdev。
+- bizdev 仍以类型别名导出，既有调用方编译通过。
+- arch-check 收紧 intent allowlist。
+
+## 三、 测试方案与环境 (Test Plan & Environment)
+
+| 项 | 值 |
+|----|-----|
+| OS | Linux 7.0.0-31-generic |
+| Go | go1.27.1 linux/amd64 |
+| 分支 | `fix/intent-bizdev-boundary` |
+| 层级 | 表征/单元 + arch-check |
+
+## 四、 预期结果 (Expected Results)
+
+intent 既有 ADVANCE_STAGE 槽位测试仍过；token 黄金不变。
+
+## 五、 实际测试结果与判定 (Actual Results & Evaluation)
+
+### 5.1 表征
+
+- **测试输入 (Input)**：`go test -short -count=1 ./internal/intent ./internal/maturity ./internal/bizdev ./internal/archtest`
+- **实际输出 (Actual Output)**：四包 ok（intent 0.010s，maturity 0.001s，bizdev 0.129s，archtest 0.117s）
+- **评价判定 (Evaluation / Verdict)**：**PASS**
+- **性能与耗时 (Duration & Latency)**：~0.26s
+
+### 5.2 arch-check
+
+- **测试输入 (Input)**：`./scripts/arch-check.sh --mode block`
+- **实际输出 (Actual Output)**：`arch-check block: production gate passed`
+- **评价判定 (Evaluation / Verdict)**：**PASS**
+- **性能与耗时 (Duration & Latency)**：~0.11s
+
+## 六、 自动化测试套件汇总 (Test Suite Execution)
+
+| 命令 | 结果 |
+|------|------|
+| intent/maturity/bizdev/archtest | PASS |
+| arch-check | PASS |
+
+## 七、 测试结论与后续优化建议 (Conclusion & Next Steps)
+
+D7a **PASS**。coordinator 仍依赖 bizdev DTO（D5）；chatflow 阶段常量可在 D7b 首批改为 maturity。
