+工程 (Project)
+ └── 测线 (Session)
+      └── 测点 (Frame)
+           ├── 元数据 (GPS/电流/温度/姿态角...)
+           └── 波形数据 (.bin 文件)
+```
+
+### 数据库表
+
+- `projects` — 工程信息
+- `sessions` — 测线，必须归属工程
+- `frames` — 测点，关联测线和 .bin 波形文件
+
+### 导出格式
+
+- **CSV** — 测线级导出，包含所有测点的元数据和各通道峰值
+- **.tem** — 工程级导出，ZIP 压缩包含 `project.json` 和所有 `.bin` 波形文件
+
+### TEMF 二进制格式
+
+每个测点的波形数据存储为 `.bin` 文件（TEMF v1 格式）：
+- 64 字节文件头：通道数、采样深度、GPS、电流、温度、姿态角等
+- 数据区：int32 LE，按通道顺序存储

+# TriloopTem App 商业化审计报告
+
+> 审计日期：2026-06-20
+> 审计范围：代码质量、UX 健壮性、安全性、性能、数据完整性
+> 总计问题：36 项（致命 4 / 高 13 / 中 14 / 低 5）
+
+---
+
+## 一、代码质量与架构
+
+### 1.1 [致命] 生产代码中有大量调试日志
+
+**文件及行号：**
+- `src/services/TcpService.ts` — 第 38, 45, 51, 65, 68, 70, 75, 83, 125, 129 行（10 处）
+- `src/services/DeviceService.ts` — 第 30, 111-114, 149, 153, 159 行（5 处）
+- `src/protocol/parser.ts` — 第 58-61, 64, 71, 77 行（4 处）
+
+**问题描述：**
+总计约 20 处 `console.log` / `console.warn` 调用。其中 TcpService 第 51 和 68 行在每个 TCP data 事件上做 `Array.from(...).map(b => '0x' + b.toString(16))` 十六进制格式化，DeviceService 第 111-114 行在每帧数据到达时循环打印各通道的原始 ADC 值。在 250kHz 六通道连续采集时，这些日志每秒触发数百次，产生大量 GC 压力。
+
+**修复方案：**
+删除所有 `console.log` / `console.warn`，或用 `if (__DEV__)` 包裹。建议封装一个 `logger` 模块，在 release 构建中为 no-op。
+
+---
+
+### 1.2 [高] IP 地址和端口号缺少格式校验
+
+**文件：** `src/components/modals/ConnectModal.tsx` 第 42-43 行
+
+**问题描述：**
+连接弹窗仅检查 `!host.trim()` 和 `isNaN(port)`，接受诸如 `999.999.999.999` 等无效 IP，端口号也没有范围限制（1-65535）。
+
+**修复方案：**
+在连接前用正则或 IP 解析函数校验地址格式，端口校验 `port >= 1 && port <= 65535`。
+
+---
+
+### 1.3 [高] 心跳写入失败被静默吞掉
+
+**文件：** `src/services/TcpService.ts` 第 97-99 行
+
+**问题描述：**
+心跳定时器每 8 秒写 `'0'` 到 socket，外层 `try/catch` 捕获所有异常但不做任何处理。如果 socket 处于半断开状态，心跳持续失败但 `this.connected` 仍为 `true`，用户无法感知连接已断。
+
+**修复方案：**
+在 catch 中将 `this.connected` 设为 `false`，调用 `this.callbacks?.onError()`，触发重连流程。
+
+---
+
+### 1.4 [高] 数据库查询使用 `any` 类型
+
+**文件：** `src/services/StorageService.ts` 第 247 行
+
+**问题描述：**
+`getAllAsync<any>` 绕过了 TypeScript 类型检查。如果后续数据库 schema 变更（列名改动），运行时会产生 `undefined` 值但编译阶段无法发现。
+
+**修复方案：**
+为每个查询定义明确的行类型接口，替换 `any`。
+
+---
+
+### 1.5 [中] TcpService 单例无防重复连接保护
+
+**文件：** `src/services/TcpService.ts` 第 23-30 行
+
+**问题描述：**
+在已连接状态下调用 `connect()` 不会先断开旧连接。`createSocket()` 虽然销毁旧 socket，但旧的 reconnect 定时器可能仍在运行，回调引用也未清理。
+
+**修复方案：**
+在 `connect()` 开头调用 `this.disconnect()` 确保干净状态。
+
+---
+
+### 1.6 [中] 分帧传输状态使用模块级变量，断线后不重置
+
+**文件：** `src/services/DeviceService.ts` 第 24-26 行
+
+**问题描述：**
+`splitChunks`、`splitActive`、`splitFrameNo` 是模块级 `let` 变量。如果分帧传输中途断线重连，这些状态不会重置，下次分帧传输会拼接到旧的脏数据上。
+
+**修复方案：**
+在 `onClose` 回调中重置分帧状态，或在 `deviceStartSplitFrame` 开始时清理。
+
+---
+
+### 1.7 [中] `clearTimeout` 对可能为 null 的值使用 `!` 断言
+
+**文件：** `src/services/TcpService.ts` 第 43, 113, 137 行
+
+**问题描述：**
+`clearTimeout(this.reconnectTimer!)` 虽然在大多数 JS 引擎中对 null 不会崩溃，但 `!` 非空断言不正确，严格模式下可能隐藏问题。
+
+**修复方案：**
+改为 `if (this.reconnectTimer) clearTimeout(this.reconnectTimer)`。
+
+---
+
+### 1.8 [低] 导出函数缺少返回类型注解
+
+**文件：** `src/services/DeviceService.ts` 第 28, 172-186 行
+
+**问题描述：**
+`handleIncomingFrame`、`deviceStartSplitFrame` 等公共 API 函数没有显式返回类型。
+
+**修复方案：**
+为所有 `export` 函数添加返回类型注解。
+
+---
+
+### 1.9 [低] filePrefix 默认值在模块加载时计算，跨天不更新
+
+**文件：** `src/stores/deviceStore.ts` 第 29 行
+
+**问题描述：**
+`new Date().toISOString().slice(0,10).replace(/-/g,'')` 仅在模块首次加载时执行一次。如果 App 过了午夜仍在运行，文件前缀还是昨天的日期。
+
+**修复方案：**
+在创建新采集会话时动态生成日期前缀，或在每天零点时刷新。
+
+---
+
+## 二、UX 与健壮性
+
+### 2.1 [致命] ACK 竞态条件——并发请求覆盖
+
+**文件：** `src/services/DeviceService.ts` 第 147-170 行
+
+**问题描述：**
+`pendingAcks` 以 func code 为 key 存储 Promise resolver。如果用户快速连续点击（如双击"下发配置"按钮），第二次 `pendingAcks.set()` 会静默覆盖第一次的 resolver，第一个 Promise 永远不会 resolve，直到 5 秒超时才报错。
+
+**修复方案：**
+在覆盖前先 reject 已有的 pending promise，或使用队列/序列号机制。UI 层也应在 `busy` 状态下禁用按钮（已部分实现但需确认所有路径）。
+
+---
+
+### 2.2 [高] TCP 初始连接无超时
+
+**文件：** `src/services/TcpService.ts` 第 32-91 行
+
+**问题描述：**
+`TcpSocket.createConnection` 没有连接超时设置。如果设备不可达，可能挂起 75+ 秒等待操作系统级 TCP 超时。期间 UI 显示"连接中"但无法取消。
+
+**修复方案：**
+添加 10 秒连接超时：如果在超时内未收到 `onConnect` 回调，销毁 socket 并调用 `onError`。可以在 `createSocket()` 中启动一个定时器，`onConnect` 时清除。
+
+---
+
+### 2.3 [高] clearHistory 只清内存不清数据库
+
+**文件：** `src/stores/dataStore.ts` 第 62 行
+
+**问题描述：**
+`clearHistory` 仅清空内存中的 `history` 数组和 `currentFrame`，但 SQLite 中的帧数据和磁盘上的 bin 文件不受影响。用户以为"清除"了数据，实际上数据仍然存在。
+
+**修复方案：**
+要么连同数据库和文件一起删除，要么将按钮文案改为"清除显示"并向用户说明数据仍已保存。
+
+---
+
+### 2.4 [高] 分享功能不可用时无用户反馈
+
+**文件：** `src/utils/export.ts` 第 94-99 行
+
+**问题描述：**
+`shareFile` 调用 `Sharing.isAvailableAsync()` 检测分享是否可用，如果不可用则静默返回。用户点击"导出"后看到 CSV 文件生成但什么也没发生。
+
+**修复方案：**
+在分享不可用时弹出 Alert 提示，或提供复制文件路径的选项。
+
+---
+
+### 2.5 [中] 操作前不检查连接状态
+
+**文件：** `src/hooks/useDevice.ts` 第 35-78 行
+
+**问题描述：**
+`setup`、`startContinuous`、`startSingle` 在发送命令前不检查是否已连接。当未连接时，`sendAndWaitAck` 会立即 reject "TCP not connected"，但用户看到的提示是"配置超时"而非"未连接"。
+
+**修复方案：**
+在每个操作开始时检查 `tcpService.isConnected()`，未连接时显示明确的"请先连接设备"提示。
+
+---
+
+### 2.6 [中] wave.tsx 项目名加载无错误处理
+
+**文件：** `app/(tabs)/wave.tsx` 第 396-400 行
+
+**问题描述：**
+动态 import + 异步链没有 `.catch()` 处理。如果 `listProjects()` 失败，Promise rejection 未被捕获。
+
+**修复方案：**
+添加 `.catch(() => setProjectName(null))`。
+
+---
+
+### 2.7 [中] CSV 导出只导出内存中的帧
+
+**文件：** `app/(tabs)/records.tsx` 第 113 行
+
+**问题描述：**
+`exportCsv(history, sessionId)` 只导出当前内存中的帧数据（最多 `MAX_HISTORY = 500` 帧）。如果用户采集了 1000 帧，CSV 中只有最近 500 帧，且用户不知情。
+
+**修复方案：**
+从数据库导出全部帧，或在导出前提示用户当前仅包含内存中的 N 帧。
+
+---
+
+### 2.8 [低] 大项目导出无进度指示
+
+**文件：** `src/services/StorageService.ts` 第 336-393 行
+
+**问题描述：**
+`exportProject` 对大项目可能耗时较长（读取所有 bin 文件），虽然提供了 `onProgress` 回调，但调用方需确保显示进度 UI。
+
+**修复方案：**
+在项目导出时显示进度条或加载动画。
+
+---
+
+## 三、安全性
+
+### 3.1 [高] 原始数据被打印到日志
+
+**文件：**
+- `src/services/TcpService.ts` 第 51, 68, 125 行
+- `src/services/DeviceService.ts` 第 111-114 行
+
+**问题描述：**
+原始 TCP 载荷的十六进制内容和各通道 ADC 数值被打印到 console。在 Android 上，`console.log` 输出可通过 `adb logcat` 被任何持有 `READ_LOGS` 权限的应用读取。对于地球物理勘探数据，这可能涉及商业敏感信息。
+
+**修复方案：**
+同 1.1，移除或用 `__DEV__` 门控。
+
+---
+
+### 3.2 [中] 项目名/文件名未做文件系统安全过滤
+
+**文件：** `src/services/StorageService.ts` 第 104-112, 390 行
+
+**问题描述：**
+`createProject` 使用 `name.trim()` 但不过滤文件系统特殊字符。`exportProject` 第 390 行直接将项目名拼入文件路径 `TEM_${proj.name}_${Date.now()}.tem`。包含 `/`、`\`、`..` 或空字节的项目名可能导致路径穿越或文件创建失败。
+
+**修复方案：**
+对项目名做白名单过滤（只允许字母、数字、中文、下划线、短横线），或在文件名中使用项目 ID 代替名称。
+
+---
+
+### 3.3 [中] GPS 坐标明文存储
+
+**文件：** `src/services/StorageService.ts` 第 58-69 行
+
+**问题描述：**
+GPS 经纬度、海拔以明文存储在 SQLite 中，zustand 持久化文件也是明文 JSON。
+
+**修复方案：**
+评估是否需要静态加密。如果需要，可使用 `expo-crypto` 或 SQLCipher。对于大多数行业仪器 App 这不是硬性要求，但需在隐私政策中声明。
+
+---
+
+### 3.4 [低] filePrefix 输入未做字符过滤
+
+**文件：** `src/components/ParamForm.tsx` 第 183 行
+
+**问题描述：**
+`filePrefix` 只限制了长度（15 字符）但未过滤特殊字符。该字段仅用于协议包构建（不进 SQL），风险较低。
+
+**修复方案：**
+添加正则校验，只允许字母、数字、下划线。
+
+---
+
+## 四、性能
+
+### 4.1 [致命] 热路径上的重量级调试计算
+
+**文件：**
+- `src/services/TcpService.ts` 第 51, 68 行
+- `src/services/DeviceService.ts` 第 111-114 行
+
+**问题描述：**
+每个 TCP data 事件都做 `Array.from(arr.slice(0, 20)).map(...)` 创建中间数组和字符串。每帧测量数据到达时循环各通道做 `Array.from()` + `.toFixed()`。连续采集时每秒触发数百次。
+
+**修复方案：**
+同 1.1，直接删除。
+
+---
+
+### 4.2 [高] Parser 缓冲区溢出时静默丢弃数据
+
+**文件：** `src/protocol/parser.ts` 第 27-29 行
+
+**问题描述：**
+当 `this.len + incoming.length > capacity`（2MB）时，直接 `this.len = 0` 重置缓冲区，丢弃所有已缓存数据。无错误回调，无日志，用户无感知。在高吞吐量连续采集时可能导致数据丢失。
+
+**修复方案：**
+至少触发一个错误回调通知上层。考虑动态扩容或增大默认容量。记录溢出事件以便排查。
+
+---
+
+### 4.3 [高] 内存中历史帧可能导致 OOM
+
+**文件：** `src/stores/dataStore.ts` 第 47 行
+
+**问题描述：**
+每个 `MeasurementFrame` 包含 `adcRaw: Int32Array[]` 和 `adcUV: Float64Array[]`。以 6 通道 2000 采样深度计算，每帧约 `6 × 2000 × (4 + 8) = 144 KB`。`MAX_HISTORY = 500` 时内存占用可达 **72 MB**。中低端手机可能 OOM 崩溃。
+
+**修复方案：**
+- 方案 A：将 `MAX_HISTORY` 降至 50
+- 方案 B：内存中只存元数据和峰值摘要，完整波形按需从 bin 文件加载
+- 方案 C：历史帧只保留 `adcUV`，不保留 `adcRaw`（节省 1/3 内存）
+
+---
+
+### 4.4 [中] 缩放/拖拽时每帧重建 Skia Path
+
+**文件：** `src/components/WaveformChart.tsx` 第 204-222 行
+
+**问题描述：**
+`channelPaths` 的 `useMemo` 依赖 `toY`、`xMinMs`、`xMaxMs`，这些在每次手势更新时都会变化。每个手势帧都触发全量重新计算所有通道的 Skia Path（最多 512 点/通道 × 6 通道）。
+
+**修复方案：**
+在固定坐标系中构建 Path，用 Skia 矩阵变换实现平移缩放，避免逐帧重建 Path。
+
+---
+
+### 4.5 [中] 降采样使用简单抽取，可能遗漏尖峰
+
+**文件：** `src/hooks/useWaveform.ts` 第 15-22 行
+
+**问题描述：**
+当前降采样每隔 N 个取一个点。对于测量仪器来说，这可能完全遗漏瞬态尖峰信号，导致显示的峰值与实际不符。
+
+**修复方案：**
+使用 min-max 降采样（每组取最大值和最小值各一个点）或 LTTB 算法，确保极值被保留。
+
+---
+
+### 4.6 [中] PeakRow 每次渲染都重新计算峰值
+
+**文件：** `app/(tabs)/wave.tsx` 第 294-297 行
+
+**问题描述：**
+`ch.reduce((m, v) => Math.max(m, Math.abs(v)), 0)` 在每次组件渲染时对每个可见通道运行一次。对于大数组（2000+ 点）这是不必要的开销。
+
+**修复方案：**
+在帧接收时计算峰值并缓存到 `MeasurementFrame`，或用 `useMemo` 包裹。
+
+---
+
+### 4.7 [低] Base64 编码产生大量中间字符串
+
+**文件：** `src/services/BinLoader.ts` 第 68-75 行
+
+**问题描述：**
+`u8ToBase64` 将二进制数据拆成 8192 字节块，逐块 `String.fromCharCode` 再 `btoa`。6 通道 2000 点的帧约 48KB 二进制 → 64KB base64 字符串。批量导出时内存抖动明显。
+
+**修复方案：**
+考虑使用 `expo-file-system` 的直接二进制写入能力，或流式处理。
+
+---
+
+## 五、数据完整性
+
+### 5.1 [致命] importProject 中 gain 列写入了错误值
+
+**文件：** `src/services/StorageService.ts` 第 480-484 行
+
+**问题描述：**
+SQL INSERT 的 `gain` 参数位置（第 10 个参数）使用了 `meta.ampRatio`（增益 code，如 3 代表 1×），而不是实际增益倍数（`AMP_GAIN[meta.ampRatio]`，即 1）。导致导入的数据在重新加载时，电压换算使用错误的增益值，波形幅度错误。
+
+**修复方案：**
+第 483 行改为 `AMP_GAIN[meta.ampRatio] ?? 1`。
+
+---
+
+### 5.2 [高] 数据库迁移无版本管理
+
+**文件：** `src/services/StorageService.ts` 第 73-78 行
+
+**问题描述：**
+当前通过 `try { ALTER TABLE } catch {}` 添加 `project_id` 列。这种方式只能处理单次迁移，随着 App 迭代新增更多 schema 变更时无法可靠管理。没有版本号追踪，无法知道数据库处于什么状态。
+
+**修复方案：**
+实现基于 `PRAGMA user_version` 的迁移系统：
+```typescript
+const version = await db.getFirstAsync<{user_version:number}>('PRAGMA user_version');
+if (version.user_version < 1) {
+  await db.runAsync('ALTER TABLE sessions ADD COLUMN project_id TEXT');
+  await db.runAsync('PRAGMA user_version = 1');
+}
+if (version.user_version < 2) {
+  // 下一次迁移...
+  await db.runAsync('PRAGMA user_version = 2');
+}
+```
+
+---
+
+### 5.3 [高] 删除项目不级联删除关联数据
+
+**文件：** `src/services/StorageService.ts` 第 139-142 行
+
+**问题描述：**
+`deleteProject` 只删除 `projects` 表中的记录。关联的 sessions（`project_id` 被 SET NULL）、frames 记录和磁盘上的 bin 文件都成为孤儿数据，永远不会被清理。
+
+**修复方案：**
+删除项目时，先查出关联的 sessions，再删除对应的 frames 和 bin 文件，最后删除 sessions 和 project 记录。
+
+---
+
+### 5.4 [高] persistFrame 使用 INSERT OR REPLACE 可能静默覆盖数据
+
+**文件：** `src/services/StorageService.ts` 第 224 行
+
+**问题描述：**
+如果由于 bug 或竞态条件，两帧具有相同的 `(frameId, sessionId)` 主键，第二帧会静默覆盖第一帧的数据，无任何警告。
+
+**修复方案：**
+改用 `INSERT OR IGNORE` 并记录警告日志，或在插入前检查唯一性。
+
+---
+
+### 5.5 [中] Session/Project ID 可能冲突
+
+**文件：**
+- `src/stores/dataStore.ts` 第 113-119 行
+- `src/services/StorageService.ts` 第 95-101 行
+
+**问题描述：**
+`generateSessionId` 和 `generateProjectId` 使用秒级时间戳生成 ID。如果在同一秒内创建两个会话或项目，ID 会重复。`ensureSession` 使用 `INSERT OR IGNORE`，第二个会话会静默复用第一个。
+
+**修复方案：**
+添加随机后缀（如 4 位随机字母数字），或使用 UUID，或至少使用毫秒精度。
+
+---
+
+### 5.6 [中] CSV 导出未转义特殊字符
+
+**文件：**
+- `src/utils/export.ts` 第 28-47 行
+- `src/services/StorageService.ts` 第 318-327 行
+
+**问题描述：**
+CSV 值直接用逗号拼接，未做引号包裹或转义。虽然数值字段一般不含逗号，但如果 UTC 字符串在某些 locale 下包含逗号，CSV 格式会错乱。
+
+**修复方案：**
+对所有字段做标准 CSV 转义：包含逗号、引号或换行的值用双引号包裹，值内的双引号用两个双引号转义。
+
+---
+
+### 5.7 [中] 帧计数器内存与数据库可能不同步
+
+**文件：** `src/stores/dataStore.ts` 第 38-41 行
+
+**问题描述：**
+`nextFrameId` 在 zustand 内存中递增，`persistFrame` 通过 `void` 异步调用（fire-and-forget）。如果 `persistFrame` 失败（如磁盘满），内存中计数器继续递增但数据库缺少对应帧，间隙永远不会被检测到。
+
+**修复方案：**
+`await persistFrame` 或至少处理其 rejection（记录错误，通知用户，重试）。
+
+---
+
+### 5.8 [中] 导入项目时临时文件清理为 fire-and-forget
+
+**文件：** `src/services/StorageService.ts` 第 430 行
+
+**问题描述：**
+`FileSystem.deleteAsync(tmpPath, ...).catch(() => {})` 静默忽略清理失败。多次失败的导入会在设备上累积临时文件。
+
+**修复方案：**
+跟踪临时文件并定期清理，或 await 删除操作并在失败时记录。
+
+---
+
+### 5.9 [低] parseAck 读取 reason 字符串时未检查 payload 长度
+
+**文件：** `src/protocol/parser.ts` 第 189-195 行
+
+**问题描述：**
+reason 字符串从 payload offset 22 开始读取，但没有检查 `payload.length >= 22`。如果设备返回一个短 ACK 包，循环会读取到 `undefined`，`String.fromCharCode(undefined)` 得到乱码。
+
+**修复方案：**
+在读取前检查 `if (payload.length < reasonOffset) return { result, reason: '' }`。
+
+---

+        "ascAppId": "App Store Connect中的App ID（上架时填写）"
+      }
+    }
+  }
+}
+```
+
+### 5.3 确保代码在 Git 仓库中
+
+EAS 需要 Git 仓库：
+
+```bash
+git add -A
+git commit -m "准备 EAS 构建"
+```
+
+---
+
+## 六、构建 Android
+
+### 6.1 Preview 版（内部测试用 APK）
+
+```bash
+eas build --platform android --profile preview
+```
+
+首次构建会提示：
+- **Generate a new Android Keystore?** → 选 **Yes**（EAS 自动管理签名密钥）
+
+构建过程（约 10-20 分钟）：
+1. 代码上传到 EAS 云端
+2. 云端安装依赖
+3. 编译生成 APK
+4. 提供下载链接
+
+### 6.2 Production 版（正式发布用）
+
+```bash
+eas build --platform android --profile production
+```
+
+### 6.3 下载 APK
+
+构建完成后终端会显示下载链接，也可以在 https://expo.dev 的项目页面查看。
+
+```bash
+# 查看构建列表
+eas build:list --platform android
+```
+
+---
+
+## 七、构建 iOS
+
+### 7.1 首次构建
+
+```bash
+eas build --platform ios --profile production
+```
+
+首次构建会依次提示以下内容：
+
+#### 第 1 步：Apple 账号登录
+
+```
+? Do you want to log in to your Apple account? › Yes
+
+? Apple ID: › 输入你的 Apple ID 邮箱
+? Password: › 输入密码
+```
+
+如果开启了双重认证，会要求输入 6 位验证码。
+
+#### 第 2 步：选择开发者团队
+
+```
+? Select Team › 
+  ❯ XXXXXXXX - 你的名字/公司名 (Team ID)
+```
+
+选择你的开发者团队。
+
+#### 第 3 步：Bundle Identifier 确认
+
+```
+? Bundle Identifier: › com.triloop.temreceiver
+```
+
+直接回车使用默认值。
+
+#### 第 4 步：签名证书管理
+
+```
+? How would you like to manage your credentials? ›
+  ❯ Let Expo handle it (Recommended)
+    I want to provide my own
+```
+
+**选择 "Let Expo handle it"**。EAS 会自动：
+- 创建 Distribution Certificate（发布证书）
+- 创建 Provisioning Profile（配置文件）
+- 安全存储在 EAS 服务器上
+
+#### 第 5 步：等待构建
+
+iOS 构建约 15-30 分钟。进度可在终端或 https://expo.dev 查看。
+
+### 7.2 后续构建
+
+第二次及以后的构建不再需要上述交互，直接运行：
+
+```bash
+eas build --platform ios --profile production
+```
+
+### 7.3 下载 IPA
+
+```bash
+eas build:list --platform ios
+```
+
+或访问 https://expo.dev 项目页面下载。
+
+---
+
+## 八、安装到设备
+
+### 8.1 Android
+
+下载 APK 后直接安装：
+
+```bash
+adb install app-xxx.apk
+```
+
+或将 APK 发送到手机上点击安装。
+
+### 8.2 iOS — 内部测试（Ad Hoc）
+
+**注意**：需要先注册测试设备的 UDID。
+
+#### 注册测试设备
+
+1. 手机 Safari 访问 https://expo.dev/register-device
+2. 安装描述文件获取 UDID
+3. 在 EAS 中注册设备：
+
+```bash
+eas device:create
+```
+
+按提示输入设备 UDID 和名称。
+
+#### 构建 Ad Hoc 版本
+
+```bash
+eas build --platform ios --profile preview
+```
+
+构建完成后生成安装链接，在手机 Safari 中打开即可安装。
+
+### 8.3 iOS — TestFlight 分发
+
+适合分发给多人测试：
+
+#### 提交到 App Store Connect
+
+```bash
+eas submit --platform ios
+```
+
+提示：
+```
+? Select a build to submit › 选择最近的构建
+? Apple ID: › 你的 Apple ID
+```
+
+提交后：
+1. 登录 https://appstoreconnect.apple.com
+2. 进入「我的 App」→ 选择 App → TestFlight
+3. 等待 Apple 审核（通常几分钟到几小时）
+4. 审核通过后添加内部/外部测试人员
+5. 测试人员在 TestFlight App 中安装
+
+---
+
+## 九、上架应用商店（可选）
+
+### 9.1 Google Play
+
+1. 注册 Google Play 开发者账号（$25 一次性）：https://play.google.com/console/signup
+2. 在 Google Play Console 创建应用
+3. 构建 AAB 格式：
+
+修改 `eas.json` 的 production profile：
+```json
+"production": {
+  "android": {
+    "buildType": "app-bundle"
+  }
+}
+```
+
+```bash
+eas build --platform android --profile production
+eas submit --platform android
+```
+
+### 9.2 App Store
+
+1. 在 App Store Connect 创建 App：https://appstoreconnect.apple.com
+2. 填写 App 信息（名称、描述、截图、分类等）
+3. 提交构建：
+
+```bash
+eas build --platform ios --profile production
+eas submit --platform ios
+```
+
+4. 在 App Store Connect 中选择构建版本
+5. 提交审核（通常 24-48 小时）
+
+---
+
+## 十、常用命令速查
+
+```bash
+# ── 账号 ──
+eas login                          # 登录
+eas whoami                         # 查看当前账号
+
+# ── 构建 ──
+eas build -p android               # 构建 Android（默认 production）
+eas build -p ios                   # 构建 iOS
+eas build -p all                   # 同时构建双平台
+eas build -p android --profile preview  # 指定 profile
+eas build:list                     # 查看构建历史
+eas build:cancel                   # 取消当前构建
+
+# ── 设备管理（iOS Ad Hoc）──
+eas device:create                  # 注册测试设备
+eas device:list                    # 查看已注册设备
+
+# ── 提交商店 ──
+eas submit -p android              # 提交到 Google Play
+eas submit -p ios                  # 提交到 App Store
+
+# ── 证书管理 ──
+eas credentials                    # 管理签名证书
+```
+
+---
+
+## 十一、常见问题
+
+### Q: 构建失败，提示 "Missing credentials"
+**A:** 运行 `eas credentials` 重新配置签名证书。
+
+### Q: iOS 构建提示 "No bundle identifier"
+**A:** 确认 `app.json` 中 `ios.bundleIdentifier` 已填写。
+
+### Q: 免费额度用完了怎么办
+**A:** 等下个月刷新（每月 30 次），或改用本地构建（Android 用 `build-release.bat`，iOS 需要 Mac）。
+
+### Q: 不想用 EAS 管理证书，可以自己管理吗
+**A:** 可以。首次构建时选 "I want to provide my own"，然后上传你的 .p12 证书和 .mobileprovision 文件。
+
+### Q: Android 签名密钥丢了怎么办
+**A:** EAS 自动管理的密钥存储在 Expo 服务器，不会丢失。可以用 `eas credentials` 随时下载备份。
+
