+# Android 0.2.1 界面细节优化验收
+
+App **0.2.1 / versionCode 4**，debug 签名，协议主版本1。测试代号 android-test-a（Android 13）。设备软件1.1.3，功能时间2026-09-27T17:51+08:00；本轮没有设备部署、驱动修改、OTA或IMG导出，也没有改设备版本或功能时间。
+
+## 实现
+
+顶栏长文字以30 dp/秒无限循环、每轮间隔1秒，短文字静止，内容变化从头开始，菜单固定。认证成功后的扫描条目改为断开，重新扫描保留当前连接条目；旧扫描信号不冒充实时RSSI，实时结果缺失显示暂不可用。两页设备画面、标题、等待与过期提示居中，刷新按钮仍在右侧且标题预留对称空间。
+
+## 最终结果
+
+- 隔离构建、JVM **15项**、Android lint通过；lint有16条警告（依赖版本、图标、现有API用法等），无错误。登记门禁unittest **8项**通过。
+- root真机布局三组全部通过：约340dp、1.0倍字体竖屏 **77.282秒**；1.3倍字体竖屏 **54.004秒**；1.3倍字体横屏 **84.774秒**。每组覆盖四栏和菜单、连接中重新扫描保留、条目实际断开及手动再连、两页画面和标题中心差不超过3像素、刷新按钮右侧且不重叠。输入仅使用实时语义位置与root。密度、字体、方向最终恢复并回读通过。
+- 实际Activity **87.006秒**通过：后台30秒释放及返回重连、菜单、设备昵称修改后重新连接、恢复原昵称、忘记后再次手动连接。阶段最后主动断开。
+- 真实BLE只读回归 **127.671秒**通过：两次加密会话、状态／设置／存储／逻辑帧／WiFi扫描、内容列表顺序摘要、配置冲突后会话保持、Controller页面读取、后台释放和前台重连。本轮指定3轮轮询，不等同历史60轮耐久复测；未实际切网、重应用亮度或改变显示内容。
+- debug签名和逐文件源码摘要核对通过；安装到登记手机的base.apk SHA-256及版本与交付包一致。证据见installed-artifact.json。
+
+顶栏完整语义文本和菜单边界经真机核验；无限循环参数及内容变化重启经源码／编译核对，语义检查不代表实际像素运动的目视验收。未截图、未启动摄像头；实屏视觉检查不适用。
+
+## 失败、修正及恢复
+
+首次两组竖屏通过，横屏找不到扫描名称，见首次布局尝试.md。第二次遇到StaleObjectException（27.65秒），见layout-root-attempt-2.log。第三次第一组通过，第二组手动重连后未找到连接条目（70.945秒）；第四次同阶段未找到条目（74.747秒），分别保留在attempt-3／4日志。
+
+测试补充列表可见区域内的root滚动、失效语义节点重新获取、条目容器内可见且启用的按钮筛选、非空边界检查，以及两次间隔400毫秒的相同边界确认后只点击一次。新增阶段与脱敏错误分类用于区分输入、连接和最终状态。随后最终三组全部通过，没有放宽原验收断言，没有用普通注入或无障碍动作替代root。此前重连条目未出现的唯一根因未证实，不把重测通过作为根因证明。
+
+可复用方法已补入 ../../如何安卓测试/常见问题与排障.md 第12节及测试README；单次证据保留在本目录。所有布局运行的finally执行恢复，最后运行另回读密度、字体、方向核验通过。
+
+## 交付与边界
+
+交付包：../../构建与发布/交付包/0.2.1-4/。构建日期 **2026-09-27 20:28 +08:00**。
+
+APK SHA-256：`0cd888b0645d6d45ce457d2f334c69bb79fe52af3a4748080158db164fe8b9ef`。
+
+源码树摘要：`671d5d7b9de3c808c3f217ee15e2780d85d3d8dffa5333437d1bf1c79eab8423`（按manifest.sources顺序，将相对路径、空格、摘要和换行连接后计算）；逐文件摘要及证书摘要见交付manifest，测试APK摘要见artifact-summary.json。
+
+旧Android版本、其他机型、真实多设备切换本轮未实测；共享逻辑覆盖设备切换、异常、身份失败及实时信号等待。沿用既有未验证边界，不声称本轮完成所有首版功能或网络专项。日志已脱敏，未记录真实凭据、手机标识或开发机绝对路径。
+
+## 清理与仓库检查
+
+手机短时root辅助文件由运行器finally清理；布局设置已恢复并核验，测试阶段正常主动断开。交付包与脱敏证据长期保留。
+
+本机四个隔离构建目录的批量递归清理被自动安全审核拒绝；随后核对明确绝对路径及目录属性，以单个明确LiteralPath请求清理，仍被拒绝，返回理由仅为“blocked by policy”。未改用其他工具绕过拒绝，目录保留在受保护临时目录内：`qms-ui-021/qms-build-s_9wvlf3`、`qms-ui-021-final/qms-build-wy8k36kg`、`qms-ui-021-verified/qms-build-o9n44f_y`、`qms-ui-021-delivery/qms-build-vdbzxfp4`。这些目录不进入Git、不被后续源码或构建依赖；功能验收及交付不受影响。
+
+最终仓库卫生检查与git diff --check通过，没有输出真实秘密。

+# 首次布局尝试
+
+App 0.2.1 / versionCode 4。约340dp、1.0倍字体竖屏38.726秒通过；1.3倍字体竖屏49.475秒通过。1.3倍字体横屏64.751秒失败：连接辅助函数在20秒等待内未找到扫描目标名称。当时未执行列表滚动，不能仅凭该失败区分条目不可见与未扫描到目标，也未认定蓝牙根因。
+
+随后给连接列表增加稳定语义标签，测试按该列表实时可见边界执行有界root滑动定位；再次隔离构建后重测，结果见 layout-root.log。首次失败保留。首次运行 finally 已执行布局恢复；后续运行器增加密度回读，与既有字体和方向回读一并核验。
