+# Playwright intent-plan 双标签测试报告
+
+## 一、 测试背景 (Background)
+覆盖 no-go 后实施 intent-plan confirm 双标签真浏览器门禁。
+
+## 二、 测试目标 (Test Objectives)
+- RUN_UI_ACCEPTANCE=1 下双标签互斥
+- 默认 skip 不冒充 PASS
+
+## 三、 测试方案与环境 (Test Plan & Environment)
+- Playwright；`PLAYWRIGHT_BASE_URL` 默认 :5173
+
+## 四、 预期结果 (Expected Results)
+- 无 env → skip
+- 有 env + fixture → 第二标签不本地双成功
+
+## 五、 实际测试结果与判定 (Actual Results & Evaluation)
+- Input: 默认 `npx playwright test web/e2e/intent-plan-cards.spec.ts`
+- Actual: skipped unless RUN_UI_ACCEPTANCE=1
+- Verdict: PASS（门禁实现）；活跑需本机 UI
+
+## 六、 自动化测试套件汇总 (Test Suite Execution)
+见实现提交后本地 playwright list。
+
+## 七、 测试结论与后续优化建议 (Conclusion & Next Steps)
+不升 MULTI_INTENT_PLAN_TIER。
