+WiFi 加速与回退专项见 [WiFi 传输测试](WiFi传输测试.md)，必须显式按影响选测。

 **先读 [按影响选测](按影响选测.md)。以下矩阵列出可选覆盖，不是每轮必跑清单；历史版本专项仅在相关影响存在时执行。**
 
 本文件维护步骤与合格标准，不写一次性通过结果。每轮测试前阅读 [常见问题与排障](常见问题与排障.md)，优先沿用已验证方法。结果记录到 `../测试结果归档/`。真机先检查 `测试设备登记/prepare_test_device.py`，多机精确选择，日志仅使用代号。源码与 UI 尚未实现的测试不得写成通过。

+# WiFi 传输按影响验证
+
+适用 MOBILE-WIFI-TRANSPORT/FALLBACK/SAFETY、DEVICE-MOBILE-WIFI-TRANSPORT/LIFECYCLE、WEB-MOBILE-PRESENCE 和 TEST-MOBILE-WIFI-TRANSPORT。先读按影响选测和排障指南。下列场景须显式选择，不加入普通公共回归。
+
+## 本机与模拟器
+
+- Python：在设备源码根执行 `python -m pytest tests/test_mobile_wifi.py tests/test_mobile_session.py tests/test_mobile_protocol.py tests/test_mobile_control.py`。覆盖一次性凭据、身份、篡改、过期、重复写入、BLE 活跃超时、WiFi 超时、WebSocket、兼容统计字段和公开向量。
+- Android：隔离构建运行 `:sharedCore:jvmTest`、`:androidApp:lintDebug`、`:androidApp:assembleDebug`、`:androidApp:assembleDebugAndroidTest`、`:uiTest:assembleDebug`。WifiCryptoTest 验证 Python 向量；HybridRpcTest 验证回退不重放写入、只读重取、网络变化、BLE 心跳和恢复协程异常收敛。
+- 模拟器 `run_emulator_ui_test.py --scenario connection --scenario wifiTransport`，选 baseline 和 narrow。使用真实 Controller/Compose 与测试专用传输，验证 WiFi/蓝牙提示、权限原因/入口和断线清理；不代表真实局域网权限或无线链路已通过。
+- API 37 运行时权限必须在对应系统验证。拒绝和撤销权限时应仍可 BLE 控制，恢复权限可再探测；低版本真机不能替代此项。
+
+## 登记真机与核桃派
+
+先执行凭据脚本、手机登记与 ADB/root 门禁，核对远端工具。使用 `run_ble_test.py --scenario <场景> --adb <ADB路径> --build <本轮隔离工程目录>`。不输出真实身份、SSID、地址、凭据或原始系统网络转储。
+
+| 场景 | 操作及合格条件 |
+|---|---|
+| wifi-transport | BLE 加密握手、独立 WiFi 握手、相同未使用 App 缓存的缩略图比较，再由 HybridRpc 自动升级。连续帧/图片的 WiFi 计数增加，直接测试期间 BLE 字节不增加；记录驱动实际刷新率、截止丢失与错误。耗时是样本，不宣称固定加速倍数。 |
+| wifi-transport-recovery | 手机初始 WiFi 必须已启用。root 关闭 WiFi，回退 BLE 后状态可读；等待平台完成关闭，再启用并等实际 WiFi 网络出现；自动恢复 WiFi。关闭蓝牙则整体断开且不能继续 RPC；最终恢复两种无线开关并核验。 |
+| wifi-transport-network | 仅将核桃派当前已保存且正在使用的 WiFi 原样立即应用；保留密码，通过 BLE 查询任务，完成后核对配置并确认 WiFi 通信恢复。不是不同 SSID 或 DHCP 地址变化的证据。 |
+| wifi-transport-restart | 测试会话通过 BLE 临时改名为固定测试标记；宿主仅在该标记且 WiFi 已认证时执行一次真实 systemd restart。旧会话必须关闭，重新发现、BLE 握手和 WiFi 升级后服务实例不同、设备身份相同。 |
+| wifi-connection-entry | 生产 Activity 的 WiFi 文案、重扫保留、主动断开和重新连接；按实时语义位置 root 点击，不改变布局。 |
+
+双手机互斥在第二台手机可用时专项验证，缺少设备记未验证。跨子网可达、不同 SSID、AP 隔离等真实拓扑须分别准备环境；单元测试与“不比较 SSID”的实现不能冒充真实拓扑验收。
+
+后台生命周期保持原规则：立即停预览，30 秒关闭两通道；前台重新握手。测试前后核对配置、用户内容、服务健康与测试辅助文件清理。服务重启测试不是整机重启或 OTA 验收。普通传输修改不启动摄像头，不切换实屏测试图案。
+
+## 证据
+
+归档记录本轮源摘要、版本、场景、实际环境、结果、样本计数/耗时、恢复核验、失败与重测。日志仅保留固定阶段名、数字指标和测试代号；禁止把完整 status.get 或网络信息写入归档。必要未做项明确列出。

 # Android 测试常见问题与排障
 
+## WiFi 传输经验
+
+- 原 `mobile.transport` 是 BLE 计数对象，不能改为字符串。实际业务链路使用新增 `mobile.active_transport`；以 BluezRuntime 组合后的状态测试，避免只测试 SessionManager 漏掉字段覆盖。
+- `cmd wifi status` 的启用文字可能为 `Wifi` 或 `Wi-Fi`，只在内存中忽略大小写与连字符后判断，不输出包含 SSID/IP 的原始内容。
+- `invokeOnCompletion` 不是协程异常处理器。网络监听的 collectLatest 内恢复屏障也可能因 BLE 已断开而失败；必须在 launch 主体捕获并结束会话，不能仅在完成回调做清理，否则可能断开成功后仍崩溃。
+- 网络回调取消不能截断正在发出的加密 BLE 消息。通道协商/撤销须有界地完成 BLE 交换，再响应取消；旧网络回调按注册实例隔离。
+- 无线开关恢复分为“启用命令完成”和“网络实际可用”。测试先等关闭稳定，再启用并等待 Network 回调；一次重测通过不能单独证明此前恢复超时的根因。
+- 模拟器冷启动超时不代表 Compose 测试失败。先检查已有 Emulator、加速能力和登记系统镜像，不重复下载；可用独立进程记录启动诊断、确认 boot_completed 后运行选定场景。只关闭本次启动实例。

+App 0.3.0 / versionCode 6 增加 BLE 会话内 WiFi 加速，协议 1.2；仅 debug。Android 使用固定 OkHttp 4.12.0，Gradle verification-metadata.xml 记录依赖 SHA-256。设备复用 FastAPI/uvicorn/cryptography，无新增板端依赖。保持设备 VERSION 和发布记录，不导出 OTA/IMG。
+
 ## 安装门槛
 
 Android Studio 是正常安装软件，由用户运行已核验官方安装包。安装包放用户普通下载目录，不放仓库或 Codex bin。准备好后停止等待用户安装，不自动运行安装器。安装时建议采用默认位置，首次向导安装 Android SDK；不必创建项目，也不必先下载模拟器或 NDK。

+# WiFi 传输第一阶段验收
+
+App **0.3.0 / versionCode 6**，debug 签名；协议 **1.2**。设备 VERSION 维持 **1.1.3**，功能时间 **2026-10-01T10:37+08:00**。未导出 OTA/IMG，未改显示驱动或用户内容。
+
+交付：`../../构建与发布/交付包/0.3.0-6/`。手机安装 APK 与交付包 SHA-256 一致：`0aa43b8d6cb64648aad4fb5bff6a9b5e3eb3b71b707a17bc67708d197b54e36d`。设备修改文件摘要与源码一致，主服务、BLE 和驱动可用；最终打开生产 App 后设备报告 active_transport=wifi。
+
+## 变更与选测
+
+改动共享 RPC、BLE 会话、Android 网络监听/权限、连接栏和网页状态，故选择协议、状态机、定向真实 BLE/WiFi、真实主服务重启和连接栏测试。普通设置/图库页面、驱动输出和实屏视觉未改变，不跑无关全量回归，不使用摄像头。
+
+| 层级/场景 | 结果与边界 |
+|---|---|
+| Python 设备侧 | 45 项通过；公开向量、会话、业务、真实 ASGI WebSocket、过期/重放/身份/互斥门禁、兼容统计字段；隔离源码副本再次 45 项通过。 |
+| sharedCore JVM | 23 项通过；含 WiFi 跨语言向量 2 项和混合路由 4 项。写入结果不明不重放、只读回退、BLE 心跳和恢复屏障异常有测试。 |
+| 构建/lint | debug 产品/测试 APK 和 uiTest 构建成功；lint 0 errors、20 warnings。依赖校验元数据已保存。 |
+| 宿主选测/网页 | 选测运行器 9 项通过；device UI Node 测试及修改 JavaScript 语法检查通过。网页文案依赖真实 active_transport，昵称仍以 textContent 渲染。未声称浏览器视觉验收。 |
+| 模拟器 connection | API 35，baseline/narrow 均通过。 |
+| 模拟器 wifiTransport | API 35，baseline/narrow 均通过；WiFi 提示、蓝牙回退、权限原因/入口和断开清理。使用假平台，不代表系统权限实测。 |
+| wifi-transport-recovery | 登记 Android 13 真机通过，20.443 秒：自动升级、手机 WiFi 关闭后 BLE 可读、WiFi 恢复再升级、蓝牙关闭整体断开且未崩溃；无线开关恢复并核验。 |
+| wifi-transport-network | 真机通过，20.223 秒：核桃派原网络原配置重新应用、保留密码、BLE 查询任务、WiFi 恢复与配置回读一致。不等于换 SSID 或 DHCP 换地址。 |
+| wifi-transport-restart | 真机与真实 systemd 通过，24.256 秒：活动 WiFi 会话中重启主服务，旧会话断开，新 BLE 握手、相同设备身份、不同服务实例、WiFi 再升级。不是 OTA 验收。 |
+| wifi-connection-entry | 生产 Activity root 语义输入通过，52.854 秒；实际 WiFi 标识、重扫保留、断开和手动再连，未修改密度/方向。 |
+| 部署核验 | 设备源摘要匹配、服务 active、驱动 running 且无最后错误。手机安装摘要匹配交付包，WiFi/蓝牙均恢复。 |
+
+## 传输证据
+
+同一 64×64 PNG 缩略图（Base64 300 字符），未使用 App 图片缓存：恢复专项 BLE 89 ms / WiFi 12 ms；网络专项 91 / 14 ms；重启专项 134 / 21 ms。这些是小样本单次请求，不能外推固定加速倍数或大图库性能。
+
+重启专项额外连续读取图片和当前帧：WiFi 请求计数增加 7，BLE 接收字节增量为 0，证明业务走 WiFi。该短窗口驱动约 97.416 Hz，截止丢失 1→1，driver running、last_error 空。较早健康核验约 97.332 Hz、累计截止丢失 1；收尾再次核验约 97.331 Hz、累计截止丢失 16，驱动仍运行且无最后错误。累计计数随运行增加，未做长期负载因果对照，不能据此宣称长期无退化。
+
+## 失败、修复与重测
+
+1. Kotlin 跨模块可空属性不能 smart cast，使用明确空值处理；OkHttp 的 Protocol 与项目 Protocol 同名，改用显式 import。构建重测通过。
+2. 旧测试固定协议次版本 1，随兼容扩展改为 2 并校验能力。新增 runtime 组合状态测试：原 transport 是统计对象，新增 active_transport，避免字段覆盖和旧客户端破坏。
+3. WiFi 启用状态文本 Wifi/Wi-Fi 大小写差异导致运行器误拒绝；在内存归一化，不输出原始网络资料。门禁重测通过。
+4. 首次实机关闭 BLE 后恢复协程异常逃逸导致测试进程退出。launch 主体捕获恢复屏障异常并补 JVM 回归；完整实机恢复重测通过。
+5. 续跑时一次 WiFi 恢复等待 45 秒超时。加入平台关闭稳定等待与“网络实际可用”阶段诊断后通过；不能只因通过就断言此前唯一根因。
+6. API 35 模拟器首次冷启动 180 秒超时，未运行 UI。检查 WHPX 可用，复用已有镜像，以独立 headless 实例记录诊断并确认 boot_completed，再跑选择场景，4 项均通过。只关闭本轮模拟器。
+7. 隔离设备副本首次遗漏 VERSION，测试收集失败；补齐部署元数据后 45 项通过。该失败是副本准备不足，不是源码依赖原工作区。
+
+## 未验证与不适用
+
+- API 37 系统局域网权限允许/拒绝/撤销尚无对应系统实测；API 35 模拟和 Android 13 真机不能替代。
+- 第二台实体手机互斥、真实不同 SSID/跨子网/AP 隔离、IPv4 地址变化未具备本轮环境；对应协议门禁及不依赖 SSID 的实现不等于真实拓扑通过。
+- 混合通道的生产 App 前后台补测未执行：自动审批拒绝 ADB root Home/重新打开操作，仅返回 blocked by policy。保持现有 30 秒释放逻辑，不能据历史纯 BLE 测试声明本轮混合通道已通过。
+- IPv6、热点、WiFi Direct、独立 WiFi 会话、云连接不属于本阶段。实屏视觉不适用，未启动摄像头或切换测试图案。
+
+经验已更新 `../../如何安卓测试/常见问题与排障.md`；可重复步骤见 `../../如何安卓测试/WiFi传输测试.md`。本报告只记录本轮事实，不替代稳定测试流程。
+
+收尾已删除本轮两个远端临时部署目录，保留可回滚程序备份。脱敏测试结果见 `test-evidence.json`，最终只读健康状态见 `final-health.json`。
+
+## 用户重新授权后的 ADB 复核
+
+用户明确再次授权后，USB 登记、ADB 身份及 root（uid 0）检查通过；生产 App 进程存在，root 启动 MainActivity 成功。随后包含 root Home、后台 35 秒检查和重新打开 App 的命令被执行工具自动审批再次拒绝，仅返回 `blocked by policy`，命令未启动。未更换调用方式绕过拒绝，混合通道前后台补测仍未验证。该拒绝不能解释为手机 USB、ADB 或 root 不可用。

+- MOBILE-WIFI-TRANSPORT：两端已有 WiFi 且 BLE 会话有效时自动探测，实际可达即启用，不比较 SSID 或限制同子网。IPv4 首版不包含热点、WiFi Direct、独立 WiFi 或云连接。
+- MOBILE-WIFI-FALLBACK：WiFi 使用期间 BLE 每 2 秒保活；WiFi 失败回退，2/5/10/30 秒退避再试；蓝牙断开整体断开。网络事件撤销旧通道；静默故障目标 10 秒内回退。
+- MOBILE-CONNECTION-TRANSPORT：连接页当前设备“已连接”左侧显示“连接状态：蓝牙/WiFi”，列表一致、窄屏换行。权限拒绝仍可蓝牙控制，提供局域网授权入口。
+- MOBILE-WIFI-SAFETY：身份绑定当前 BLE 会话；不重放结果不明的写操作，回读并提示。后台立即停预览，30 秒释放全部连接。

+能力 wifi_transport。加密 BLE transport.offer 返回 channel_id（16 随机字节小写 hex）、secret（32 随机字节 Base64）、device_id、host（当前 WiFi IPv4）、port=8080、path=/ws/mobile、expires_in_ms=10000。每次 offer 撤销前一候选；活动通道须先 close。BLE transport.close 在串行门禁内撤销候选与活动通道，作为回退执行屏障。session.*、wifi.*、task.get 与通道协商只走 BLE。
+
+KDF：T=SHA256(ASCII(channel_id))；HKDF-SHA256(secret,salt=T,info=ASCII("QMS-WIFI-1")||T,length=72)。密钥及 nonce prefix 布局沿用 BLE Cipher，AAD 标签为 QMS-WIFI-1；双向序号独立从 0 开始，不共享 BLE 计数。最大加密记录 65536 字节。
+
+WebSocket 首个二进制消息为 ASCII(channel_id) 的 32 字节加加密 JSON {device_id}，5 秒内送达；设备验证凭据、BLE 会话及身份后一次消费，返回加密 {device_id,ready:true}。之后每条二进制消息为加密 RPC JSON，格式沿用原协议；WiFi 请求编号独立递增。transport.ping 是 WiFi 唯一通道级方法，每 5 秒调用、5 秒超时，不延长 BLE 活跃时间。设备 10 秒无有效 WiFi 消息撤销通道。
+
+会话锁串行业务和撤销；BLE 断开使 WiFi 失效。只读失败回退后可重取；写入结果不明不重放，回读并提示。旧凭据、错误身份、篡改、重放、非二进制、超长消息拒绝；凭据不进 URL/日志/磁盘。未认证连接不得踢掉合法通道。WiFi 建立不增加 mobile.generation；mobile.active_transport 为 ble/wifi/null。
