# 智能戒指健康 App（M0+M1 静态页面）实施计划
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** 交付一个可运行的 Android App 骨架：四个 Tab（健康首页/运动/设备/我的）加数据详情子页，全部页面静态可用，数据来自 Mock，UI 只依赖仓库接口，为 M2 接入厂商蓝牙 SDK 预留清晰边界。
**Architecture:** 单 `:app` Gradle 模块 + 严格分包（`core/` `domain/` `data/` `feature/`）。UI 只依赖 `domain/repository` 的接口与 `domain/model` 的模型；阶段一注入 `data/mock/` 的 Mock 实现。所有页面为纯静态/演示数据，M2 只需新增一套实现同样接口的 SDK 适配层，UI 零改动。
**Tech Stack:** Kotlin 2.2.20、Jetpack Compose（BOM 2026.09.00）、Navigation-Compose 2.10.1、Material 3、AGP 8.13.1、Gradle 8.14、JDK 17、JUnit4 + kotlinx-coroutines-test 1.10.2。
**Spec:** [docs/superpowers/specs/2026-09-10-ring-health-app-design.md](../specs/2026-09-10-ring-health-app-design.md)
## Global Constraints
- **仓库名**：`ring-health-app`、`ring-health-api`（kebab-case，与 Gitea 上名称一致）。
- **包名/namespace**：`com.placeholder.ringhealth`（占位，后续按 spec §12 统一替换）。
- **SDK 版本**：`minSdk 26` / `targetSdk 36` / `compileSdk 36` / `buildToolsVersion "36.1.0"`（36.1.0 是本机已装版本，写死避免下载）。
- **工具链钉死**：Gradle `8.14`、AGP `8.13.1`、Kotlin `2.2.20`（三者均为本机缓存版本）。
- **依赖约束**：阶段一**不引入** Hilt、Room、Retrofit、第三方图表库。图表一律用 Compose `Canvas` 手绘。
- **不硬编码文案**：所有用户可见文字进 `res/values/strings.xml`（默认中文）。
**唯一豁免**（见 ledger Ruling R13）：`core/common/Formatters.kt` 中
`formatSleepDuration`（`7小时32分`）与 `formatDuration`（`1小时05分`）这两条 ——
它们是数字与单位**黏合成单一复合值**、且设计系统没有独立单位槽位可放的时长排版，
拆开会把同一段 `when` 逻辑复制进每个调用点。除此之外，格式化函数**一律不得**拼接
用户可见文字：单位与描述词要么由调用点用资源提供（如 `formatCalories` 的「千卡」），
要么以 `@StringRes` 返回资源 id（如 `stressLevelLabelRes`）。判据是
「该文字是否已在 `strings.xml` 里有第二份」与「设计系统是否已提供独立槽位」。
- **禁止行内样式散落**：颜色/字号统一定义在 `core/designsystem/`，页面不得直接写 `Color(0xFF...)`。
- **命名规范**：类/Composable 用 PascalCase；函数/变量用 camelCase；资源文件用 kebab-case/snake_case。
`const val` 编译期常量用 UPPER_SNAKE_CASE。
**例外**：`core/designsystem/` 里的设计 token（`BrandGreen`、`MetricRed`、`AppBackground`、
`MetricValueStyle` 等）一律用 PascalCase —— 它们是 Compose 惯用的公开设计 token，不是 `const val`，
且 Tasks 3–12 的组件与页面都按这些确切名字引用，改名会破坏接口契约。此例外即本约束的一部分。
- **注释规范**：每个类与公开函数上方写中文 KDoc，说明用途（团队规范要求）。
- **提交规范**：每个 Task 结束提交一次；提交信息用中文，前缀 `feat:` / `chore:` / `test:` / `docs:`。
- **Gitea 地址**：`http://120.192.101.56:3000/cuiluzheng/<repo>.git`（凭据助手已按主机配置好，可直接推送）。
- **不做 `installDebug`**：本机没有模拟器镜像、也没有连接真机，各 Task 的构建步骤**只跑 `./gradlew assembleDebug`**
（ledger Ruling R21）。运行时的界面/交互验证统一顺延到 Task 14 Step 3 的人工验收清单，交人在有设备时执行。
执行 agent 不要尝试 `installDebug`，也不要临时下载模拟器镜像。
- **每个页面必须拆成「有状态外壳 + 无状态内容」并给内容加 `@Preview`**（ledger Ruling R26）：
公开的 `XScreen(modifier, viewModel)` 只负责 `collectAsStateWithLifecycle` 并委托，
真正渲染的是 `private fun XContent(state, …, modifier)`，`@Preview` 挂在后者上、传入手写的示例 state。
Task 8 的 `HomeScreen` / `HomeContent` / `HomeContentPreview` 是样板。
理由不只是惯例：本机**没有任何设备**（见上一条），IDE Preview 是 Task 14 人工验收之前
**唯一**能让人看见界面的手段；没有它，Task 9–12 四个页面到验收前都只有编译期保证。
同时这天然把「渲染」与「取数」分开，`XContent` 可以直接拿假数据测。
- **次要文字一律用 `core/designsystem/` 的 `TextSecondary`**，不要用 `MaterialTheme.colorScheme.onSurfaceVariant`
（ledger Ruling R26）：主题只覆写了 `surface`/`background`/`surfaceVariant` 等槽位，
`onSurfaceVariant` 仍是 Material 默认的 `#FF49454F`，而 `TextSecondary` 是 `#FF8E8E93` ——
两者都是灰但深浅明显不同，混用会让同一屏里的次要文字深浅不一。
这是「禁止行内样式散落」的延伸：槽位不是字面量，所以编译器拦不住，只能靠这条约定。

**职责边界：**
- `domain/` 是纯 Kotlin，**不允许** import `android.*` 或 `androidx.*`（保证可单元测试、可复用）。
- `feature/*` 只依赖 `domain/model` 与 `domain/repository`，**不允许**直接 import `data/mock/*`。
- `core/designsystem/` 不依赖任何 `feature/` 或 `data/`。
- 厂商 SDK 相关代码在 M2 才出现，将放在独立包 `com.sr.smartring`（原样拷贝）与 `data/sdk/`（我们的适配层），本计划不创建。
---
### Task 1: 仓库初始化 + Gradle 工程骨架（空壳可构建）
**Files:**
- Create: `repos/ring-health-app/.gitignore`, `README.md`, `settings.gradle.kts`, `build.gradle.kts`, `gradle.properties`, `local.properties`, `gradle/libs.versions.toml`, `gradle/wrapper/gradle-wrapper.properties`, `gradlew`, `gradlew.bat`, `gradle/wrapper/gradle-wrapper.jar`（从厂商工程拷贝）
- Create: `app/build.gradle.kts`, `app/proguard-rules.pro`
- Create: `app/src/main/AndroidManifest.xml`
- Create: `app/src/main/java/com/placeholder/ringhealth/MainActivity.kt`
- Create: `app/src/main/res/values/{strings.xml, themes.xml}`, `res/xml/{backup_rules.xml, data_extraction_rules.xml}`
- Create: `app/src/main/res/drawable/ic_launcher_foreground.xml`, `res/values/ic_launcher_background.xml`, `res/mipmap-anydpi-v26/{ic_launcher.xml, ic_launcher_round.xml}`
**Interfaces:**
- Consumes: 无（首个任务）
- Produces: 一个可通过 `./gradlew assembleDebug` 的工程骨架；`MainActivity` 承载后续 Compose 内容。
- [ ] **Step 1: 创建目录并拷贝 gradle wrapper**
本机无全局 gradle，但 Gradle 8.14 发行包已在缓存中。复用厂商工程的 wrapper 引导文件（wrapper 与 Gradle 版本无关，只负责按 `distributionUrl` 下载/复用发行包）：
```bash
mkdir -p /d/cherry/repos/ring-health-app/{app/src/main/java/com/placeholder/ringhealth,app/src/main/res/values,app/src/main/res/xml,app/src/main/res/drawable,app/src/main/res/mipmap-anydpi-v26,gradle/wrapper,app/src/test/java/com/placeholder/ringhealth}
cp /d/cherry/SmartRingF01_SDK/gradlew /d/cherry/SmartRingF01_SDK/gradlew.bat /d/cherry/repos/ring-health-app/
cp /d/cherry/SmartRingF01_SDK/gradle/wrapper/gradle-wrapper.jar /d/cherry/repos/ring-health-app/gradle/wrapper/
```
- [ ] **Step 2: 写 `.gitignore`**
`repos/ring-health-app/.gitignore`:
```gitignore
*.iml
.gradle/
local.properties
.idea/
.DS_Store
build/
captures/
.externalNativeBuild/
.cxx/
*.apk
*.aab
*.keystore
*.jks
```
- [ ] **Step 3: 写 `gradle/wrapper/gradle-wrapper.properties`**
```properties
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-8.14-all.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
```
- [ ] **Step 4: 写 `gradle/libs.versions.toml`**
```toml
[versions]
agp = "8.13.1"
kotlin = "2.2.20"
coreKtx = "1.19.0"
activityCompose = "1.13.0"
lifecycle = "2.11.0"
navigationCompose = "2.10.1"
composeBom = "2026.09.00"
iconsExtended = "1.7.8"
coroutines = "1.10.2"
junit = "4.13.2"
[libraries]
androidx-core-ktx = { group = "androidx.core", name = "core-ktx", version.ref = "coreKtx" }
androidx-activity-compose = { group = "androidx.activity", name = "activity-compose", version.ref = "activityCompose" }
androidx-lifecycle-runtime-compose = { group = "androidx.lifecycle", name = "lifecycle-runtime-compose", version.ref = "lifecycle" }
androidx-lifecycle-viewmodel-compose = { group = "androidx.lifecycle", name = "lifecycle-viewmodel-compose", version.ref = "lifecycle" }
androidx-lifecycle-viewmodel-ktx = { group = "androidx.lifecycle", name = "lifecycle-viewmodel-ktx", version.ref = "lifecycle" }
androidx-navigation-compose = { group = "androidx.navigation", name = "navigation-compose", version.ref = "navigationCompose" }
androidx-compose-bom = { group = "androidx.compose", name = "compose-bom", version.ref = "composeBom" }
androidx-ui = { group = "androidx.compose.ui", name = "ui" }
androidx-ui-graphics = { group = "androidx.compose.ui", name = "ui-graphics" }
androidx-ui-tooling = { group = "androidx.compose.ui", name = "ui-tooling" }
androidx-ui-tooling-preview = { group = "androidx.compose.ui", name = "ui-tooling-preview" }
androidx-material3 = { group = "androidx.compose.material3", name = "material3" }
androidx-icons-extended = { group = "androidx.compose.material", name = "material-icons-extended", version.ref = "iconsExtended" }
kotlinx-coroutines-test = { group = "org.jetbrains.kotlinx", name = "kotlinx-coroutines-test", version.ref = "coroutines" }
junit = { group = "junit", name = "junit", version.ref = "junit" }
[plugins]
android-application = { id = "com.android.application", version.ref = "agp" }
kotlin-android = { id = "org.jetbrains.kotlin.android", version.ref = "kotlin" }
kotlin-compose = { id = "org.jetbrains.kotlin.plugin.compose", version.ref = "kotlin" }
```
> 说明：`material-icons-extended` 已被官方冻结在 `1.7.8`（新版 BOM 不再收录），因此**显式钉版本、不走 BOM**。它只提供 `ImageVector` 数据，与新版 Compose UI 共存无碍。若构建仍报冲突，回退方案见 Task 14 备注。
- [ ] **Step 5: 写根 `build.gradle.kts` 与 `settings.gradle.kts`**
`repos/ring-health-app/settings.gradle.kts`:
```kotlin
pluginManagement {
repositories {
google {
content {
includeGroupByRegex("com\\.android.*")
includeGroupByRegex("com\\.google.*")
includeGroupByRegex("androidx.*")
}
}
mavenCentral()
gradlePluginPortal()
}
}
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
}
}
rootProject.name = "ring-health-app"
include(":app")
```
`repos/ring-health-app/build.gradle.kts`:
```kotlin
plugins {
alias(libs.plugins.android.application) apply false
alias(libs.plugins.kotlin.android) apply false
alias(libs.plugins.kotlin.compose) apply false
}
```
`repos/ring-health-app/gradle.properties`:
```properties
org.gradle.jvmargs=-Xmx2048m -Dfile.encoding=UTF-8
org.gradle.parallel=true
org.gradle.caching=true
android.useAndroidX=true
android.nonTransitiveRClass=true
kotlin.code.style=official
```
- [ ] **Step 6: 写 app 模块 `app/build.gradle.kts`**
```kotlin
plugins {
alias(libs.plugins.android.application)
alias(libs.plugins.kotlin.android)
alias(libs.plugins.kotlin.compose)
}
android {
namespace = "com.placeholder.ringhealth"
compileSdk = 36
buildToolsVersion = "36.1.0"
defaultConfig {
applicationId = "com.placeholder.ringhealth"
minSdk = 26
targetSdk = 36
versionCode = 1
versionName = "0.1.0"
testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
isMinifyEnabled = false
proguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro")
}
}
compileOptions {
sourceCompatibility = JavaVersion.VERSION_17
targetCompatibility = JavaVersion.VERSION_17
}
buildFeatures {
compose = true
}
packaging {
resources.excludes += "/META-INF/{AL2.0,LGPL2.1}"
}
}
// Kotlin 编译选项须放在 android {} 之外（AGP 8.x 起 android.kotlinOptions 已废弃）。
kotlin {
compilerOptions {
jvmTarget.set(org.jetbrains.kotlin.gradle.dsl.JvmTarget.JVM_17)
}
}
dependencies {
implementation(libs.androidx.core.ktx)
implementation(libs.androidx.activity.compose)
implementation(libs.androidx.lifecycle.runtime.compose)
implementation(libs.androidx.lifecycle.viewmodel.compose)
implementation(libs.androidx.lifecycle.viewmodel.ktx)
implementation(libs.androidx.navigation.compose)
implementation(platform(libs.androidx.compose.bom))
implementation(libs.androidx.ui)
implementation(libs.androidx.ui.graphics)
implementation(libs.androidx.ui.tooling.preview)
implementation(libs.androidx.material3)
implementation(libs.androidx.icons.extended)
debugImplementation(libs.androidx.ui.tooling)
testImplementation(libs.junit)
testImplementation(libs.kotlinx.coroutines.test)
}
```
`app/proguard-rules.pro` 保持空文件（内容仅一行注释）：
```proguard
# 阶段一未启用混淆，规则留空。
```
- [ ] **Step 7: 写 `local.properties`（不进版本库）**
```properties
sdk.dir=C\:\\Users\\10314\\AppData\\Local\\Android\\Sdk
```
- [ ] **Step 8: 写清单、资源与最小 Activity**
`app/src/main/AndroidManifest.xml`:
```xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
<application
android:name=".RingHealthApplication"
android:allowBackup="true"
android:dataExtractionRules="@xml/data_extraction_rules"
android:fullBackupContent="@xml/backup_rules"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/Theme.RingHealth">
<activity
android:name=".MainActivity"
android:exported="true"
android:screenOrientation="portrait"
android:theme="@style/Theme.RingHealth">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
```
> `RingHealthApplication` 在 Task 4 创建。此步骤先创建占位类，见下方 Step 8b。
`app/src/main/java/com/placeholder/ringhealth/RingHealthApplication.kt`（Task 4 会补上容器，这里先最小化）:
```kotlin
package com.placeholder.ringhealth
import android.app.Application
/**
* 应用入口。同时作为手动依赖注入的组合根（M1 阶段只持有 Mock 容器）。
*/
class RingHealthApplication : Application()
```
`app/src/main/java/com/placeholder/ringhealth/MainActivity.kt`:
```kotlin
package com.placeholder.ringhealth
import android.os.Bundle
import androidx.activity.ComponentActivity
import androidx.activity.compose.setContent
import androidx.activity.enableEdgeToEdge
import androidx.compose.foundation.layout.Box
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.Surface
import androidx.compose.material3.Text
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.res.stringResource
/** 唯一 Activity，承载 Compose 界面。 */
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
enableEdgeToEdge()
setContent {
MaterialTheme {
Surface(modifier = Modifier.fillMaxSize()) {
Box(modifier = Modifier.fillMaxSize(), contentAlignment = Alignment.Center) {
Text(stringResource(R.string.app_name))
}
}
}
}
}
}
```
`app/src/main/res/values/strings.xml`:
```xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">RingHealth</string>
</resources>
```
`app/src/main/res/values/themes.xml`:
```xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Theme.RingHealth" parent="android:Theme.Material.Light.NoActionBar">
<item name="android:statusBarColor">@android:color/transparent</item>
<item name="android:windowLightStatusBar">true</item>
</style>
</resources>
```
`app/src/main/res/xml/backup_rules.xml`:
```xml
<?xml version="1.0" encoding="utf-8"?>
<full-backup-content />
```
`app/src/main/res/xml/data_extraction_rules.xml`:
```xml
<?xml version="1.0" encoding="utf-8"?>
<data-extraction-rules>
<cloud-backup />
<device-transfer />
</data-extraction-rules>
```
`app/src/main/res/drawable/ic_launcher_foreground.xml`（占位矢量图标，内嵌于 Task 14 可再美化）:
```xml
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="108dp"
android:height="108dp"
android:viewportWidth="108"
android:viewportHeight="108">
<path
android:fillColor="#FFFFFF"
android:pathData="M54,30 C40,30 30,40 30,54 C30,68 40,78 54,78 C68,78 78,68 78,54 C78,40 68,30 54,30 Z M54,38 C62.8,38 70,45.2 70,54 C70,62.8 62.8,70 54,70 C45.2,70 38,62.8 38,54 C38,45.2 45.2,38 54,38 Z" />
<path
android:fillColor="#FFFFFF"
android:pathData="M54,46 L60,54 L54,62 L48,54 Z" />
</vector>
```
`app/src/main/res/values/ic_launcher_background.xml`:
```xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="ic_launcher_background">#34C759</color>
</resources>
```
`app/src/main/res/mipmap-anydpi-v26/ic_launcher.xml` 与 `ic_launcher_round.xml`（两文件内容相同）:
```xml
<?xml version="1.0" encoding="utf-8"?>
<adaptive-icon xmlns:android="http://schemas.android.com/apk/res/android">
<background android:drawable="@color/ic_launcher_background" />
<foreground android:drawable="@drawable/ic_launcher_foreground" />
</adaptive-icon>
```
- [ ] **Step 9: 写 `README.md`**
```markdown
# ring-health-app
智能戒指健康 App（原生 Android / Kotlin + Jetpack Compose）。
- 设计文档：见 `ring-health-docs` 仓库 `superpowers/specs/`
- 当前阶段：M1 静态页面（数据来自 Mock，未接入蓝牙 SDK）
## 构建
```bash
./gradlew assembleDebug # 产物在 app/build/outputs/apk/debug/
./gradlew installDebug # 安装到已连接设备
./gradlew test # 单元测试
```
要求：JDK 17、Android SDK（platform 36 / build-tools 36.1.0）。
```
- [ ] **Step 10: 构建验证**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew assembleDebug --no-daemon
```
Expected: `BUILD SUCCESSFUL`，且 `app/build/outputs/apk/debug/app-debug.apk` 存在。
（首次构建需联网下载 AndroidX/Compose 依赖，约 1–3 分钟。）
- [ ] **Step 11: 初始化 git 并推送**
```bash
cd /d/cherry/repos/ring-health-app
git init -b main
git add -A
git commit -m "chore: 初始化 Android 工程骨架（Compose + Gradle 8.14/AGP 8.13.1）"
git remote add origin http://120.192.101.56:3000/cuiluzheng/ring-health-app.git
git push -u origin main
```
Expected: 推送成功，Gitea 上 `ring-health-app` 不再是空仓。

### Task 2: 设计系统（颜色 / 字体 / 主题）
**Files:**
- Create: `app/src/main/java/com/placeholder/ringhealth/core/designsystem/Color.kt`, `Type.kt`, `Theme.kt`
- Modify: `MainActivity.kt`（用 `RingHealthTheme` 包裹内容）
**Interfaces:**
- Consumes: Task 1 的工程骨架
- Produces: `RingHealthTheme(content: @Composable () -> Unit)`；指标色常量 `MetricGreen/MetricRed/MetricBlue/MetricCyan/MetricPurple/MetricOrange/MetricYellow`，供所有页面与组件引用。
- [ ] **Step 1: 写 `Color.kt`**
```kotlin
package com.placeholder.ringhealth.core.designsystem
import androidx.compose.ui.graphics.Color
/** 品牌主色（健康绿，仿小米运动健康首页大环）。 */
val BrandGreen = Color(0xFF34C759)
val BrandGreenDark = Color(0xFF248A3D)
/** 页面与卡片背景。 */
val AppBackground = Color(0xFFF5F6F8)
val CardSurface = Color(0xFFFFFFFF)
val TextPrimary = Color(0xFF1C1C1E)
val TextSecondary = Color(0xFF8E8E93)
val DividerColor = Color(0xFFEFEFF4)
/** 各健康指标的语义色，全应用统一引用。 */
val MetricGreen = Color(0xFF34C759) // 步数
val MetricRed = Color(0xFFFF3B30) // 心率
val MetricBlue = Color(0xFF3B5BFF) // 睡眠
val MetricCyan = Color(0xFF00C7BE) // 血氧
val MetricPurple = Color(0xFFAF52DE) // 压力
val MetricOrange = Color(0xFFFF9500) // 体温
val MetricYellow = Color(0xFFFFCC00) // 血压 / 提醒
```
- [ ] **Step 2: 写 `Type.kt`**
```kotlin
package com.placeholder.ringhealth.core.designsystem
import androidx.compose.material3.Typography
import androidx.compose.ui.text.TextStyle
import androidx.compose.ui.text.font.FontWeight
import androidx.compose.ui.unit.sp
/** 大号数值样式：首页大环与详情页主数字。 */
val MetricValueStyle = TextStyle(
fontSize = 40.sp,
fontWeight = FontWeight.Bold,
color = TextPrimary,
)
/** 中等数值样式：指标卡主数字。 */
val MetricTileValueStyle = TextStyle(
fontSize = 22.sp,
fontWeight = FontWeight.SemiBold,
color = TextPrimary,
)
/** 全局字体排版。 */
val RingHealthTypography = Typography()
```
- [ ] **Step 3: 写 `Theme.kt`**
```kotlin
package com.placeholder.ringhealth.core.designsystem
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.lightColorScheme
import androidx.compose.runtime.Composable
private val RingHealthColors = lightColorScheme(
primary = BrandGreen,
onPrimary = androidx.compose.ui.graphics.Color.White,

MaterialTheme(
colorScheme = RingHealthColors,

}
```
- [ ] **Step 4: `MainActivity` 换用主题**
将 `setContent { ... }` 内容替换为：
```kotlin
setContent {
RingHealthTheme {
Surface(modifier = Modifier.fillMaxSize(), color = MaterialTheme.colorScheme.background) {
Box(modifier = Modifier.fillMaxSize(), contentAlignment = Alignment.Center) {
Text(stringResource(R.string.app_name))
}
}
}
}
```
并补充 import：`com.placeholder.ringhealth.core.designsystem.RingHealthTheme`、
`androidx.compose.ui.res.stringResource`。
注意：文案必须走 `stringResource(R.string.app_name)`，不得写成 `Text("RingHealth")` 字面量 ——
全局约束「不硬编码用户可见文案」对 Compose 里的每一处 `Text(...)` 都成立。Task 1 的初版
就是因为计划里的示例代码写成了字面量而引入该缺陷，修复轮才扳正（见 ledger 裁定）。

```
Expected: `BUILD SUCCESSFUL`。

> ②压力等级**改为返回字符串资源 id**（`stressLevelLabelRes`），中文描述进 `strings.xml`，
> 与 R3 对指标名的处理保持一致。**唯一豁免**见 Global Constraints 的说明

**Interfaces:**
- Consumes: `domain/model/*`、`domain/repository/*`
- Produces:
- `interface AppContainer { healthDataRepository; ringDeviceRepository }`、`class DefaultAppContainer : AppContainer`、`RingHealthApplication.container`
- `class MockDataProvider(seed: Long = DEFAULT_SEED, now: () -> Long = System::currentTimeMillis)`，方法：`todaySummary(): HealthSummary`、`metricHistory(metric: MetricType, range: DateRange): List<MetricPoint>`、`workouts(): List<WorkoutRecord>`、`deviceState(): RingDeviceState`、`defaultFunctionSettings(): List<DeviceFunctionSetting>`
- `class MockHealthDataRepository : HealthDataRepository`（每次发射前 `delay(200)`）
- `class MockRingDeviceRepository : RingDeviceRepository`（开关状态保存在内存 StateFlow）
> **范围说明（见 ledger Ruling R17）**：`MockDataProvider` 增加一个**可注入的时间源** `now: () -> Long`
> （默认 `System::currentTimeMillis`），`metricHistory` / `workouts` 内一律用 `now()` 而非
> `System.currentTimeMillis()`。原因：本类的 KDoc 承诺「所有方法都是确定性的（同参数返回同结果）」，
> 但直接读挂钟时 `timestamp` 会随毫秒跳动 —— brief 原先的测试 `assertEquals(first, second)`
> 因此是一条**间歇失败的 flaky 断言**（两次调用跨毫秒即挂）。注入时间源后该承诺才成立，

- [ ] **Step 4: 运行测试，确认通过**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew :app:testDebugUnitTest --tests "com.placeholder.ringhealth.data.mock.MockDataProviderTest"
```
Expected: `BUILD SUCCESSFUL`，5 个测试全部通过。
- [ ] **Step 5: 写 `MockHealthDataRepository.kt`**
```kotlin
package com.placeholder.ringhealth.data.mock
import com.placeholder.ringhealth.domain.model.DateRange
import com.placeholder.ringhealth.domain.model.HealthSummary
import com.placeholder.ringhealth.domain.model.MetricPoint
import com.placeholder.ringhealth.domain.model.MetricType
import com.placeholder.ringhealth.domain.model.WorkoutRecord
import com.placeholder.ringhealth.domain.repository.HealthDataRepository
import kotlinx.coroutines.delay
import kotlinx.coroutines.flow.Flow
import kotlinx.coroutines.flow.flow
/**
* Mock 健康数据仓库。模拟 200ms 网络/设备延迟，便于阶段一验证加载态。
*/
class MockHealthDataRepository(
private val provider: MockDataProvider = MockDataProvider(),
) : HealthDataRepository {
override fun observeTodaySummary(): Flow<HealthSummary> = flow {
delay(MOCK_DELAY_MILLIS)
emit(provider.todaySummary())
}
override fun observeMetricHistory(metric: MetricType, range: DateRange): Flow<List<MetricPoint>> = flow {
delay(MOCK_DELAY_MILLIS)
emit(provider.metricHistory(metric, range))
}
override fun observeWorkouts(): Flow<List<WorkoutRecord>> = flow {
delay(MOCK_DELAY_MILLIS)
emit(provider.workouts())
}
private companion object {
const val MOCK_DELAY_MILLIS = 200L
}
}
```
- [ ] **Step 6: 写 `MockRingDeviceRepository.kt`**
```kotlin
package com.placeholder.ringhealth.data.mock
import com.placeholder.ringhealth.domain.model.DeviceFunctionSetting
import com.placeholder.ringhealth.domain.model.RingDeviceState
import com.placeholder.ringhealth.domain.repository.RingDeviceRepository

import kotlinx.coroutines.flow.MutableStateFlow
import kotlinx.coroutines.flow.StateFlow
import kotlinx.coroutines.flow.asStateFlow
import kotlinx.coroutines.flow.update
/**
* Mock 设备仓库。开关状态保存在内存中，进程重启后重置（阶段一不做持久化）。
*
* 注意 [refreshDeviceState] 的语义：它以 **suspend 函数正常返回**表示刷新完成，
* 而**不是**靠发射新状态。`MutableStateFlow` 会抑制相等值，M1 的设备状态是常量，
* 因此刷新不会产生任何可观察的发射。调用方要展示刷新反馈，应当
* `launch { repo.refreshDeviceState(); isRefreshing = false }`，
* **不要**写成「等待下一个不同的 deviceState 发射」（那样在 M1 会永远等不到）。
*/
class MockRingDeviceRepository(
private val provider: MockDataProvider = MockDataProvider(),
) : RingDeviceRepository {
private val _deviceState = MutableStateFlow(provider.deviceState())
override val deviceState: StateFlow<RingDeviceState> = _deviceState.asStateFlow()
private val _functionSettings = MutableStateFlow(provider.defaultFunctionSettings())
override val functionSettings: StateFlow<List<DeviceFunctionSetting>> = _functionSettings.asStateFlow()

settings.map { if (it.id == id) it.copy(enabled = enabled) else it }
}
}
private companion object {
const val REFRESH_DELAY_MILLIS = 300L
}
}
```
- [ ] **Step 7: 写 `AppContainer.kt` 与更新 `RingHealthApplication.kt`**
现在 Mock 实现已存在，可以安全创建容器（ledger Ruling R1）。
`AppContainer.kt`:
```kotlin
package com.placeholder.ringhealth
import com.placeholder.ringhealth.data.mock.MockHealthDataRepository
import com.placeholder.ringhealth.data.mock.MockRingDeviceRepository
import com.placeholder.ringhealth.domain.repository.HealthDataRepository
import com.placeholder.ringhealth.domain.repository.RingDeviceRepository
/**
* 手动依赖注入容器。M2 接入 SDK 时只需在这里把 Mock 实现换成真实实现。
*/
interface AppContainer {
val healthDataRepository: HealthDataRepository
val ringDeviceRepository: RingDeviceRepository
}
/** 默认容器：阶段一全部使用 Mock 数据。 */
class DefaultAppContainer : AppContainer {
override val healthDataRepository: HealthDataRepository = MockHealthDataRepository()
override val ringDeviceRepository: RingDeviceRepository = MockRingDeviceRepository()
}
```
`RingHealthApplication.kt`（替换 Task 1 的最小实现）:
```kotlin
package com.placeholder.ringhealth
import android.app.Application
/**
* 应用入口，同时作为手动依赖注入的组合根。
*/
class RingHealthApplication : Application() {
/** 全局依赖容器。 */
lateinit var container: AppContainer
private set
override fun onCreate() {
super.onCreate()
container = DefaultAppContainer()
}
}
```
- [ ] **Step 8: 全量单元测试 + 构建验证**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew :app:testDebugUnitTest && ./gradlew assembleDebug
```
Expected: 两个命令均 `BUILD SUCCESSFUL`（Step 7 的容器代码也在本次编译范围内）。
- [ ] **Step 9: Commit**
```bash
git add -A && git commit -m "feat: 新增 Mock 数据层与依赖容器（含单元测试）"
```

### Task 7: 导航骨架（底部四 Tab + 空页面）
**Files:**
- Create: `core/navigation/Routes.kt`, `core/navigation/RingHealthApp.kt`
- Create: `feature/home/HomeScreen.kt`（占位）、`feature/workout/WorkoutScreen.kt`（占位）、`feature/device/DeviceScreen.kt`（占位）、`feature/profile/ProfileScreen.kt`（占位）
- Modify: `MainActivity.kt`
- Modify: `res/values/strings.xml`（新增 Tab 文案）
**Interfaces:**
- Consumes: Task 2/3 的主题与组件
- Produces:
- `object Routes { HOME, WORKOUT, DEVICE, PROFILE, DEVICE_SETTINGS, WORKOUT_HISTORY, DETAIL_PATTERN; fun detail(metric: MetricType): String }`
- `@Composable fun RingHealthApp()`——Scaffold + NavigationBar + NavHost
- 四个 Tab 的**占位** Composable：`HomeScreen(onOpenDetail: (MetricType) -> Unit, modifier)`、
`WorkoutScreen(modifier)`、`DeviceScreen(modifier)`、`ProfileScreen(modifier)`
（`modifier: Modifier = Modifier`，实际签名以本任务 Step 2 的代码为准）。
**注意**：`Routes.DEVICE_SETTINGS` 与 `Routes.WORKOUT_HISTORY` 在本任务**只注册、无人跳转** ——
`WorkoutScreen` 的 `onOpenHistory` 与 `DeviceScreen` 的 `onOpenSettings` 分别在 Task 9 / Task 10
才加入签名，那两个 Task 会同步更新本任务 `RingHealthApp.kt` 里的调用点。
计划早期版本在本行写过一个 `HomeScreen` 的 `onOpenWorkoutHistory` 参数，
全计划没有任何调用点（Task 8 产出的是 `HomeScreen(onOpenDetail, modifier, viewModel)`），
属笔误，已删除 —— 不要把它加回来。
- [ ] **Step 1: 写 `Routes.kt`**
```kotlin
package com.placeholder.ringhealth.core.navigation
import com.placeholder.ringhealth.domain.model.MetricType
/**
* 全局路由表。字符串集中定义，避免散落在各处。
*/
object Routes {
const val HOME = "home"
const val WORKOUT = "workout"
const val DEVICE = "device"
const val PROFILE = "profile"
const val DEVICE_SETTINGS = "device/settings"
const val WORKOUT_HISTORY = "workout/history"
/** 指标详情路由模板，参数为 MetricType.name。 */
const val DETAIL_PATTERN = "detail/{metric}"
const val DETAIL_ARG_METRIC = "metric"
/** 拼出某个指标的详情路由。 */
fun detail(metric: MetricType): String = "detail/${metric.name}"
}
```
- [ ] **Step 2: 写四个占位页面（后续 Task 替换为完整实现）**
`feature/home/HomeScreen.kt`:
```kotlin

@Composable
fun HomeScreen(
onOpenDetail: (MetricType) -> Unit,
modifier: Modifier = Modifier,

@Composable
fun ProfileScreen(modifier: Modifier = Modifier) {
Box(modifier = modifier.fillMaxSize(), contentAlignment = Alignment.Center) {
Text(stringResource(R.string.tab_profile))
}
}
```
- [ ] **Step 3: 写 `strings.xml` 的导航文案**
在 `res/values/strings.xml` 的 `<resources>` 内追加：
```xml
<string name="tab_home">健康</string>
<string name="tab_workout">运动</string>
<string name="tab_device">设备</string>
<string name="tab_profile">我的</string>
<string name="placeholder_device_settings">设备设置</string>
<string name="placeholder_workout_history">运动历史</string>

- [ ] **Step 5: 创建三个占位 Composable（Task 10/12 替换）**
`feature/device/DeviceSettingsScreen.kt`（本 Task 仅占位）:

- [ ] **Step 6: `MainActivity` 接入 `RingHealthApp`**
```kotlin
setContent {
RingHealthTheme {
Surface(modifier = Modifier.fillMaxSize(), color = MaterialTheme.colorScheme.background) {
RingHealthApp()

}
```
- [ ] **Step 7: 构建 + 安装验证**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew assembleDebug

Expected: 构建成功并装到设备/模拟器；打开 App 可见底部四个 Tab，点击可切换、互不崩溃。
- [ ] **Step 8: Commit**
```bash
git add -A && git commit -m "feat: 新增底部四 Tab 导航骨架与路由表"
```

### Task 8: 健康首页（完整实现，含 ViewModel）
**Files:**
- Create: `feature/home/HomeViewModel.kt`
- Create: `AppViewModelProvider.kt`（原属 Task 4，见 ledger Ruling R2）
- Modify: `feature/home/HomeScreen.kt`（完整实现）
- Test: `app/src/test/java/com/placeholder/ringhealth/feature/home/HomeViewModelTest.kt`
- Modify: `res/values/strings.xml`
**Interfaces:**

- Produces:
- `data class HomeUiState(val loading: Boolean, val summary: HealthSummary?, val device: RingDeviceState?)`
- `class HomeViewModel(healthDataRepository, ringDeviceRepository)` 暴露 `uiState: StateFlow<HomeUiState>`
- `object AppViewModelProvider { val Factory }` 与 `fun CreationExtras.ringHealthApplication(): RingHealthApplication`

- [ ] **Step 4: 运行测试，确认通过**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew :app:testDebugUnitTest --tests "com.placeholder.ringhealth.feature.home.HomeViewModelTest"
```
Expected: `BUILD SUCCESSFUL`。
- [ ] **Step 5: 写 `AppViewModelProvider.kt`**
本任务是 `AppViewModelProvider` 的第一个消费者，文件在这里建立（ledger Ruling R2）。
Task 9 / Task 10 会各自往 `viewModelFactory` 里**追加一个 `initializer`**，文件位置与职责不变。
```kotlin
package com.placeholder.ringhealth
import androidx.lifecycle.ViewModelProvider
import androidx.lifecycle.viewmodel.CreationExtras
import androidx.lifecycle.viewmodel.initializer
import androidx.lifecycle.viewmodel.viewModelFactory
import com.placeholder.ringhealth.feature.home.HomeViewModel
/**
* ViewModel 工厂：把容器中的仓库注入各 ViewModel。
* 每个 ViewModel 在这里注册一个 initializer；后续任务按需追加。
*/
object AppViewModelProvider {
val Factory = viewModelFactory {
initializer {
HomeViewModel(
healthDataRepository = ringHealthApplication().container.healthDataRepository,
ringDeviceRepository = ringHealthApplication().container.ringDeviceRepository,
)
}
}
}
/** 从 CreationExtras 中取出 Application 实例。 */
fun CreationExtras.ringHealthApplication(): RingHealthApplication =
this[ViewModelProvider.AndroidViewModelFactory.APPLICATION_KEY] as RingHealthApplication
```
> 说明：`MetricDetailViewModel` 需要运行时参数（指标类型），使用独立的工厂，见 Task 12。

> 说明：`buildMetricCards` 是 `@Composable`（内部调用了 `stringResource`），而 `LazyColumn` 的 content lambda 不是 Composable 上下文，所以必须在进入 `LazyColumn` 之前取值——上面的 `val cards = ...` 就是为此。
>
> **不要 import `androidx.compose.foundation.lazy.item`（ledger Ruling R24）。** 计划早期版本在这份
> import 清单里写过它，那一行**单独就能让编译失败**：`item` 是 `LazyListScope` 的**成员函数**，
> 不是顶层扩展，成员函数永远不能 import（报 `Unresolved reference: 'item'`）。
> 只有 `items(List<T>)` 是 `LazyDsl` 里的顶层扩展，才需要 import。
> `item { }` 的调用点不受影响，走成员分派即可解析。
- [ ] **Step 7: 追加首页文案与指标名到 `strings.xml`**
```xml

<string name="home_battery">电量 %1$d%%</string>
<string name="home_steps_title">今日步数</string>
<string name="home_steps_goal">目标 %1$s 步</string>
<string name="home_calories_label">千卡</string>
<string name="home_distance_label">公里</string>
<string name="home_metrics">健康指标</string>
<string name="home_not_enabled">未开启</string>
<string name="unit_bpm">次/分</string>
<string name="unit_percent">%</string>
<string name="unit_celsius">°C</string>
<string name="unit_mmhg">mmHg</string>
<string name="metric_heart_rate">心率</string>
<string name="metric_sleep">睡眠</string>
<string name="metric_blood_oxygen">血氧</string>
<string name="metric_stress">压力</string>
<string name="metric_temperature">体温</string>
<string name="metric_blood_pressure">血压</string>
<string name="metric_step">步数</string>
```
> 这批 `metric_*` 字符串同时供 Task 12 的详情页标题使用（ledger Ruling R3），是它们的唯一来源。
- [ ] **Step 8: 构建 + 单测**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew :app:testDebugUnitTest && ./gradlew assembleDebug
```
Expected: 两条命令均 `BUILD SUCCESSFUL`，测试全绿（含本任务新增的 `HomeViewModelTest`）。
界面上「设备条 / 步数大环 / 六个指标卡（血压显示未开启）/ 点击进入详情」这几条**不在本步验证**
（ledger Ruling R21：本机无模拟器与真机），顺延到 Task 14 Step 3 的人工验收清单。
- [ ] **Step 9: Commit**
```bash
git add -A && git commit -m "feat: 实现健康首页（今日大环 + 指标卡片，含 ViewModel 测试）"
```
---
### Task 9: 运动页 + 运动历史子页
**Files:**
- Create: `feature/workout/WorkoutViewModel.kt`
- Modify: `feature/workout/WorkoutScreen.kt`、`feature/workout/WorkoutHistoryScreen.kt`
- Modify: `res/values/strings.xml`、`core/navigation/RingHealthApp.kt`（把占位替换为真实页面）
**Interfaces:**
- Consumes: `HealthDataRepository`、`WorkoutRecord`
- Produces:
- `data class WorkoutUiState(val loading: Boolean, val records: List<WorkoutRecord>)`
- `class WorkoutViewModel(healthDataRepository)` 暴露 `uiState: StateFlow<WorkoutUiState>`
- `@Composable fun WorkoutScreen(onOpenHistory: () -> Unit, modifier, viewModel)`、`@Composable fun WorkoutHistoryScreen(modifier, viewModel)`
- [ ] **Step 1: 写失败的测试**
`app/src/test/java/com/placeholder/ringhealth/feature/workout/WorkoutViewModelTest.kt`
（与 Task 8 的 `HomeViewModelTest` 同形；ledger Ruling R25 —— 两个 ViewModel 的覆盖度应当一致，
不该一个测一个不测）：
```kotlin
package com.placeholder.ringhealth.feature.workout
import com.placeholder.ringhealth.data.mock.MockHealthDataRepository
import kotlinx.coroutines.Dispatchers
import kotlinx.coroutines.ExperimentalCoroutinesApi
import kotlinx.coroutines.launch
import kotlinx.coroutines.test.StandardTestDispatcher
import kotlinx.coroutines.test.advanceUntilIdle
import kotlinx.coroutines.test.resetMain
import kotlinx.coroutines.test.runTest
import kotlinx.coroutines.test.setMain
import org.junit.After
import org.junit.Assert.assertEquals
import org.junit.Assert.assertFalse
import org.junit.Before
import org.junit.Test
@OptIn(ExperimentalCoroutinesApi::class)
class WorkoutViewModelTest {
private val dispatcher = StandardTestDispatcher()
@Before
fun setUp() {
Dispatchers.setMain(dispatcher)
}
@After
fun tearDown() {
Dispatchers.resetMain()
}
@Test
fun `加载完成后输出运动记录`() = runTest(dispatcher) {
val viewModel = WorkoutViewModel(MockHealthDataRepository())
// 与 HomeViewModelTest 同理：uiState 用 WhileSubscribed 构建，
// 没有订阅者时 .value 会停在 initialValue（loading = true）。
backgroundScope.launch { viewModel.uiState.collect {} }
advanceUntilIdle()
val state = viewModel.uiState.value
assertFalse(state.loading)
assertEquals(5, state.records.size)
// Mock 的运动记录是倒序生成的，最近的在最前
assertEquals("户外跑步", state.records.first().type)
}
}
```
- [ ] **Step 1b: 运行测试，确认失败**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew :app:testDebugUnitTest --tests "com.placeholder.ringhealth.feature.workout.WorkoutViewModelTest"
```
Expected: `Unresolved reference: WorkoutViewModel`，编译失败。
- [ ] **Step 2: 写 `WorkoutViewModel.kt`**
```kotlin
package com.placeholder.ringhealth.feature.workout
import androidx.lifecycle.ViewModel
import androidx.lifecycle.viewModelScope
import com.placeholder.ringhealth.domain.model.WorkoutRecord
import com.placeholder.ringhealth.domain.repository.HealthDataRepository
import kotlinx.coroutines.flow.SharingStarted
import kotlinx.coroutines.flow.StateFlow
import kotlinx.coroutines.flow.map
import kotlinx.coroutines.flow.stateIn
/** 运动页 UI 状态。 */
data class WorkoutUiState(
val loading: Boolean,
val records: List<WorkoutRecord>,
)
/** 运动页 ViewModel。 */
class WorkoutViewModel(
healthDataRepository: HealthDataRepository,
) : ViewModel() {
val uiState: StateFlow<WorkoutUiState> = healthDataRepository.observeWorkouts()
.map { WorkoutUiState(loading = false, records = it) }
.stateIn(
scope = viewModelScope,
started = SharingStarted.WhileSubscribed(STOP_TIMEOUT_MILLIS),
initialValue = WorkoutUiState(loading = true, records = emptyList()),
)
private companion object {
const val STOP_TIMEOUT_MILLIS = 5_000L
}
}
```
- [ ] **Step 3: 把 `WorkoutViewModel` 注册到 `AppViewModelProvider`**
在 `AppViewModelProvider.kt` 的 `viewModelFactory { }` 内**追加**一个 `initializer`（ledger Ruling R2），
并在该文件顶部加 `import com.placeholder.ringhealth.feature.workout.WorkoutViewModel`：
```kotlin
initializer {
WorkoutViewModel(
healthDataRepository = ringHealthApplication().container.healthDataRepository,
)
}
```
- [ ] **Step 4: 追加文案到 `strings.xml`**
```xml
<string name="workout_start">开始运动</string>
<string name="workout_start_desc">选择运动类型，记录你的训练</string>
<string name="workout_recent">最近运动</string>
<string name="workout_empty">暂无运动记录</string>
<string name="workout_item_summary">%1$s · %2$s 公里</string>
<string name="workout_detail_calories">消耗 %1$s 千卡</string>
<string name="action_view_all">查看全部</string>
```
> **本任务不得新增无消费者的字符串资源（ledger Ruling R25）。** 计划早期版本的这份清单里还有两条
> ——`workout_detail_duration`（`时长 %1$s`）与 `workout_history`（`全部记录`）—— 全计划 grep 下来
> **一个调用点都没有**：时长已经在 `workout_item_summary` 里作为 `%1$s` 拼进去了，
> 而本任务的运动历史页没有标题栏，用不上「全部记录」。**不要把它们加回来**：
> 现在加就是新写死资源，将来若要给历史页加标题，那时再补一条也不迟。
> 同理，`WorkoutHistoryPlaceholder` 被删后，`R.string.placeholder_workout_history` 就成了孤儿 ——
> **这个先留着不动**：`placeholder_device_settings` / `placeholder_metric_detail` 会由 Task 10 / Task 12
> 各自留下同样的孤儿，与其三个任务各删一次（且互相之间看不到对方的删除），
> 不如留到最后一次性清扫。孤立的字符串资源只占几字节，不影响构建与运行。

WorkoutScreen(onOpenHistory = { navController.navigate(Routes.WORKOUT_HISTORY) })
}
composable(Routes.WORKOUT_HISTORY) {
WorkoutHistoryScreen()
}
```
并删除 `WorkoutHistoryPlaceholder` 的 import 与定义（文件 `WorkoutHistoryScreen.kt` 中不再保留占位函数）。
**同时修正底栏的高亮归属（ledger Ruling R22）。** Task 7 的 `selected = currentRoute == tab.route`
在子页位于栈顶时会**四个 Tab 全部不高亮**：`NavDestination.route` 返回的是**路由模板**
（`"detail/{metric}"`），而不是填充后的 `"detail/STEP"`；`device/settings`、`workout/history`
又都不等于任何 Tab 路由。Material3 允许零个选中项，所以不会崩，但偏离了小米运动健康
（父 Tab 应当保持点亮）。把 Route 的比较改成「先归到父 Tab，再比」：
在 `RingHealthApp.kt` 中新增（放在 `RingHealthApp` 函数之前）：
```kotlin
/**
* 把当前路由归到它所属的底部 Tab。
*
* 子页位于栈顶时，底栏应当保持父 Tab 点亮。这里必须与 `Routes.DETAIL_PATTERN`
* 比较 —— `NavDestination.route` 给出的是路由**模板**而非填充后的实际路由。
* 本 App 的路由是扁平注册的（没有嵌套导航图），`destination.hierarchy` 帮不上忙，
* 只能显式映射。
*/
private fun tabRouteFor(route: String?): String? = when (route) {
Routes.DETAIL_PATTERN -> Routes.HOME
Routes.DEVICE_SETTINGS -> Routes.DEVICE
Routes.WORKOUT_HISTORY -> Routes.WORKOUT
else -> route
}
```
再把 `RingHealthApp` 内的
```kotlin
val currentRoute = backStackEntry?.destination?.route
```
改为
```kotlin
val currentRoute = tabRouteFor(backStackEntry?.destination?.route)
```
这样 `selected = currentRoute == tab.route` 本身不用动。**三个子路由在这里一次性映射完**
（`DEVICE_SETTINGS` / `DETAIL_PATTERN` 分别由 Task 10 / Task 12 接入），
免得那两个 Task 再回来改同一个 `when`。
**顺带加固 `Routes.kt` 里的一处手工耦合（ledger Ruling R22）：**
```kotlin
/** 路由参数的键名。必须声明在 DETAIL_PATTERN 之前：模板引用它。 */
const val DETAIL_ARG_METRIC = "metric"
/** 指标详情路由模板，参数为 MetricType.name。 */
const val DETAIL_PATTERN = "detail/{$DETAIL_ARG_METRIC}"
```
原来 `"detail/{metric}"` 与 `const val DETAIL_ARG_METRIC = "metric"` 是两个各自独立的字面量，
靠人手工保持一致；改了占位符名而没改常量，导航会静默走到 Task 12 的兜底分支而不报错。
`const val` 允许引用另一个 `const val`（字符串模板里只含常量即为编译期常量），
零运行时开销。**注意 `DETAIL_ARG_METRIC` 必须声明在 `DETAIL_PATTERN` 之前**，
否则常量初始化顺序会导致编译失败。
> 注意：`WorkoutViewModel` 在运动页与历史页各创建一次实例（导航到不同 destination 时独立作用域）。阶段一数据相同，可接受；M3 引入真实数据后如需共享，再提升作用域。
- [ ] **Step 8: 构建 + 单测**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew :app:testDebugUnitTest && ./gradlew assembleDebug
```
Expected: 两条命令均 `BUILD SUCCESSFUL`；`WorkoutViewModelTest` 由 Step 1b 的 RED 转为 GREEN，
全量测试 13 项通过（Task 8 之后是 12 项，本任务 +1）。
界面上「运动 Tab 显示开始运动卡片 + 5 条记录」「查看全部跳转历史页」**不在本步验证**
（ledger Ruling R21：本机无模拟器与真机），顺延到 Task 14 Step 3 的人工验收清单。
- [ ] **Step 9: Commit**
```bash
git add -A && git commit -m "feat: 实现运动页与运动历史子页"
```

### Task 10: 设备页 + 设备设置子页
**Files:**
- Create: `feature/device/DeviceViewModel.kt`
- Modify: `feature/device/DeviceScreen.kt`、`feature/device/DeviceSettingsScreen.kt`
- Modify: `res/values/strings.xml`、`core/navigation/RingHealthApp.kt`
**Interfaces:**
- Consumes: `RingDeviceRepository`、Task 3 组件
- Produces:
- `data class DeviceUiState(val device: RingDeviceState, val settings: List<DeviceFunctionSetting>)`
- `class DeviceViewModel(ringDeviceRepository)` 暴露 `uiState: StateFlow<DeviceUiState>`、`fun setFunctionEnabled(id: String, enabled: Boolean)`
- `@Composable fun DeviceScreen(onOpenSettings: () -> Unit, modifier, viewModel)`、`@Composable fun DeviceSettingsScreen(modifier, viewModel)`
- [ ] **Step 1: 写失败的测试**
`app/src/test/java/com/placeholder/ringhealth/feature/device/DeviceViewModelTest.kt`
（与 Task 8 / Task 9 的两个 ViewModel 测试同形；ledger Ruling R27 —— 三个 ViewModel 的覆盖度应当一致）：
```kotlin
package com.placeholder.ringhealth.feature.device

import org.junit.Assert.assertTrue
import org.junit.Before
import org.junit.Test
/** 设备页 ViewModel 测试。 */
@OptIn(ExperimentalCoroutinesApi::class)
class DeviceViewModelTest {
private val dispatcher = StandardTestDispatcher()
@Before
fun setUp() {
Dispatchers.setMain(dispatcher)
}
@After
fun tearDown() {
Dispatchers.resetMain()
}
@Test
fun `输出设备状态与五个功能开关`() = runTest(dispatcher) {
val viewModel = DeviceViewModel(MockRingDeviceRepository())
backgroundScope.launch { viewModel.uiState.collect {} }
advanceUntilIdle()
val state = viewModel.uiState.value
assertEquals(78, state.device.batteryPercent)
assertEquals("1.0.5", state.device.firmwareVersion)
assertEquals(5, state.settings.size)
}
@Test
fun `setFunctionEnabled 只改目标项且可来回切换`() = runTest(dispatcher) {
val viewModel = DeviceViewModel(MockRingDeviceRepository())
backgroundScope.launch { viewModel.uiState.collect {} }
advanceUntilIdle()
// Mock 的 5 项里只有 stress 与 blood_pressure 初始为 false，其余 3 项为 true
// （见 MockDataProvider.defaultFunctionSettings）。切换 stress 后应为 4 项开启。
val target = "stress"
assertFalse(viewModel.uiState.value.settings.first { it.id == target }.enabled)
viewModel.setFunctionEnabled(target, true)
advanceUntilIdle()
assertTrue(viewModel.uiState.value.settings.first { it.id == target }.enabled)
// 关键：其它开关不受影响。只断言目标项变了，无法发现「整表被覆盖」这类回归。
assertEquals(4, viewModel.uiState.value.settings.count { it.enabled })
viewModel.setFunctionEnabled(target, false)
advanceUntilIdle()
assertFalse(viewModel.uiState.value.settings.first { it.id == target }.enabled)
}
}
```
- [ ] **Step 1b: 运行测试，确认失败**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew :app:testDebugUnitTest --tests "com.placeholder.ringhealth.feature.device.DeviceViewModelTest"
```
Expected: `Unresolved reference: DeviceViewModel`，编译失败。
- [ ] **Step 2: 写 `DeviceViewModel.kt`**
```kotlin
package com.placeholder.ringhealth.feature.device
import androidx.lifecycle.ViewModel
import androidx.lifecycle.viewModelScope
import com.placeholder.ringhealth.domain.model.DeviceFunctionSetting
import com.placeholder.ringhealth.domain.model.RingDeviceState
import com.placeholder.ringhealth.domain.repository.RingDeviceRepository
import kotlinx.coroutines.flow.SharingStarted
import kotlinx.coroutines.flow.StateFlow
import kotlinx.coroutines.flow.combine
import kotlinx.coroutines.flow.stateIn
/** 设备页 UI 状态。 */
data class DeviceUiState(
val device: RingDeviceState,
val settings: List<DeviceFunctionSetting>,
)
/** 设备页 ViewModel：设备状态 + 功能开关。 */
class DeviceViewModel(
private val ringDeviceRepository: RingDeviceRepository,
) : ViewModel() {
val uiState: StateFlow<DeviceUiState> = combine(
ringDeviceRepository.deviceState,
ringDeviceRepository.functionSettings,
) { device, settings ->
DeviceUiState(device = device, settings = settings)
}.stateIn(
scope = viewModelScope,
started = SharingStarted.WhileSubscribed(STOP_TIMEOUT_MILLIS),
initialValue = DeviceUiState(
device = ringDeviceRepository.deviceState.value,
settings = ringDeviceRepository.functionSettings.value,
),
)
/** 切换功能开关（M1 仅改内存，M2 后同步到设备）。 */
fun setFunctionEnabled(id: String, enabled: Boolean) {
ringDeviceRepository.setFunctionEnabled(id, enabled)
}
private companion object {
const val STOP_TIMEOUT_MILLIS = 5_000L
}
}
```
- [ ] **Step 3: 把 `DeviceViewModel` 注册到 `AppViewModelProvider`**
在 `AppViewModelProvider.kt` 的 `viewModelFactory { }` 内**追加**一个 `initializer`（ledger Ruling R2），
并在该文件顶部加 `import com.placeholder.ringhealth.feature.device.DeviceViewModel`：
```kotlin
initializer {
DeviceViewModel(
ringDeviceRepository = ringHealthApplication().container.ringDeviceRepository,
)
}
```
- [ ] **Step 4: 追加文案到 `strings.xml`**
```xml
<string name="device_connected">已连接</string>
<string name="device_disconnected">未连接</string>
<string name="device_battery">电量 %1$d%%</string>
<string name="device_firmware">固件版本 %1$s</string>
<string name="device_settings_title">功能设置</string>
<string name="device_more">更多设置</string>
<string name="device_switch_on">已开启</string>
<string name="device_switch_off">已关闭</string>
```
> **本任务不得新增无消费者的字符串资源（ledger Ruling R27）。** 计划早期版本的这份清单有 16 条，
> 逐条 grep 调用点后砍到 8 条。被删的 8 条是
> `device_title`（`我的设备`）、`device_charging`（`充电中`）、
> `device_find_ring` / `device_find_ring_desc`、`device_firmware_update` / `device_firmware_update_desc`、
> `device_wear_detection` / `device_wear_detection_desc` —— 全计划**零调用点**。
> 它们看起来是照着小美运动健康的设备页草拟的（查找戒指 / 固件升级 / 佩戴检测三行入口），
> 但本任务实际实现的设备页只有「戒指信息卡 + 功能开关列表 + 更多设置入口」，
> 那三行从来没有被写进任何代码。**不要把它们加回来。**
> 若 M2 真要做「查找戒指」这类入口，那时再补文案 —— 提前写好只会留下 8 条永不渲染的字符串。
> （`device_settings_hint` 不在此列，它在 Step 5 单独追加，有调用点。）

```
- [ ] **Step 3: 构建 + 单测**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew :app:testDebugUnitTest && ./gradlew assembleDebug
```
Expected: 两条命令均 `BUILD SUCCESSFUL`；全量测试仍为 15 项通过（本任务不新增测试，
只换掉一个页面的实现，纯 UI 且无 ViewModel 可测）。
界面上「“我的”Tab 显示头像卡与两组设置入口」**不在本步验证**（ledger Ruling R21：本机无模拟器与真机），
顺延到 Task 14 Step 3 的人工验收清单；本步能确认的是 `ProfileScreenPreview` 能在 Android Studio 中渲染
（R26 —— 这是本机唯一能看见界面的手段）。
> **不要用 `FROM-CACHE` 的绿当作证据。** 缓存命中时任务会标 `FROM-CACHE` 而不真正执行，看到就加 `--rerun`。
- [ ] **Step 4: Commit**
```bash
git add -A && git commit -m "feat: 实现我的页"
```

### Task 12: 指标详情子页（步数 / 心率 / 睡眠 / 血氧等）
**Files:**
- Create: `feature/detail/MetricDetailViewModel.kt`
- Modify: `feature/detail/MetricDetailScreen.kt`（替换占位）
- Modify: `core/navigation/RingHealthApp.kt`（接入真实详情页 + 支持返回）
- Modify: `res/values/strings.xml`
**Interfaces:**
- Consumes: `HealthDataRepository`、`MetricBarChart`、`StatBar`、Task 8 加入的 `R.string.metric_*`
- Produces:
- `data class MetricDetailUiState(val loading: Boolean, val metric: MetricType, val range: DateRange, val points: List<MetricPoint>)`
- `class MetricDetailViewModel(metric: MetricType, healthDataRepository)`，方法 `fun switchRange(range: DateRange)`
- `@Composable fun MetricDetailScreen(metric: MetricType, onBack: () -> Unit, modifier, viewModel: MetricDetailViewModel = viewModel(factory = MetricDetailViewModel.factory(metric)))`
- `MetricDetailViewModel.factory(metric: MetricType): ViewModelProvider.Factory`（伴生对象）
- `@Composable private fun metricTitleRes(type: MetricType): Int`（文件内私有）
> **两点范围说明**：
> - 标题用 `metricTitleRes` 映射到 `R.string.metric_*`，**不再有** `metricDisplayName`（ledger Ruling R3）。
> - 增加睡眠专属区块（`StatBar` 分期条 + 入睡/起床时间），补齐 spec §6 的 `detail/sleep` 要求（ledger Ruling R4）。
- [ ] **Step 1: 写 `MetricDetailViewModel.kt`**
```kotlin
package com.placeholder.ringhealth.feature.detail

)
/** 切换时间范围（周/月）。 */
fun switchRange(newRange: DateRange) {
range.update { newRange }
}
companion object {
private const val STOP_TIMEOUT_MILLIS = 5_000L
/** 为指定指标构造 ViewModel 工厂。 */
fun factory(metric: MetricType): ViewModelProvider.Factory = viewModelFactory {
initializer {
MetricDetailViewModel(
metric = metric,
healthDataRepository = ringHealthApplication().container.healthDataRepository,
)
}
}
}
}
```
> 说明：`ringHealthApplication()` 是 Task 4 中定义在 `com.placeholder.ringhealth` 包下的 `CreationExtras` 扩展函数，需在本文件顶部 `import com.placeholder.ringhealth.ringHealthApplication`。
- [ ] **Step 4: 追加文案到 `strings.xml`**
```xml
<string name="detail_range_week">近 7 天</string>
<string name="detail_range_month">近 30 天</string>
<string name="detail_average">平均</string>
<string name="detail_max">最高</string>
<string name="detail_min">最低</string>
<string name="detail_trend">趋势</string>
<string name="detail_sleep_stages">睡眠分期</string>
<string name="detail_sleep_deep">深睡</string>
<string name="detail_sleep_light">浅睡</string>
<string name="detail_sleep_awake">清醒</string>
<string name="detail_sleep_fall_asleep">入睡时间</string>
<string name="detail_sleep_wake_up">起床时间</string>
<string name="action_back">返回</string>
```
> `detail_average` / `detail_max` / `detail_min` 是**纯标签**，不带 `%1$s`：
> `StatLine` 把标签和数值分成左右两栏渲染，标签里再带占位符会原样打印出 `%1$s`。

- [ ] **Step 4: 在 `RingHealthApp.kt` 接入真实详情页**
```kotlin
composable(

) { entry ->
// 参数无法解析属于编程错误，直接抛（ledger Ruling R22）：这里原先是
// `?: MetricType.STEP`，一旦路由模板与 Routes.detail() 拼串不一致，
// 页面会静默显示步数的数据而不报错 —— 那是「错数据」而不是「响亮失败」。
val raw = requireNotNull(entry.arguments?.getString(Routes.DETAIL_ARG_METRIC)) {
"详情路由缺少参数 ${Routes.DETAIL_ARG_METRIC}"
}
val metric = requireNotNull(MetricType.entries.firstOrNull { it.name == raw }) {
"无法识别的指标：$raw"
}
MetricDetailScreen(metric = metric, onBack = { navController.popBackStack() })
}
```
**同时补一条不需要设备的 JVM 测试（ledger Ruling R22）**，把「路由模板」与
`Routes.detail()` 的拼串锁在一起 —— Task 7 的审查指出这两者目前靠人手工同步，
而本 App 的路由是纯 Kotlin、不含任何 `android.*`，完全可以在 `src/test` 里断言：
`app/src/test/java/com/placeholder/ringhealth/core/navigation/RoutesTest.kt`:
```kotlin
package com.placeholder.ringhealth.core.navigation
import com.placeholder.ringhealth.domain.model.MetricType
import org.junit.Assert.assertEquals
import org.junit.Assert.assertTrue
import org.junit.Test
/** 路由表的一致性测试：模板与实际拼出的路由必须始终吻合（ledger Ruling R22）。 */
class RoutesTest {
@Test
fun `detail 拼出的路由能被详情模板匹配`() {
val expectedPrefix = Routes.DETAIL_PATTERN.substringBefore("{")
MetricType.entries.forEach { metric ->
val route = Routes.detail(metric)
assertTrue("$route 不以 $expectedPrefix 开头", route.startsWith(expectedPrefix))
assertEquals(metric.name, route.removePrefix(expectedPrefix))
}
}
@Test
fun `占位符名与参数常量一致`() {
assertTrue(Routes.DETAIL_PATTERN.contains("{${Routes.DETAIL_ARG_METRIC}}"))
}
}
```
跑 `./gradlew :app:testDebugUnitTest --tests "com.placeholder.ringhealth.core.navigation.RoutesTest"`，
Expected: `BUILD SUCCESSFUL`，2 项通过。
删除 `MetricDetailPlaceholder` 的定义与 import。
> 注意：详情页自带 `Scaffold` + `TopAppBar`，而外层 `RingHealthApp` 的 `Scaffold` 会传入 `innerPadding`（已用于 NavHost 的 `Modifier.padding`）。为避免底部导航重复遮罩，详情页在 NavHost 内会同时受外层 padding 影响——这是预期行为（底部栏保持可见）。
- [ ] **Step 5: 构建 + 验证**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew assembleDebug
```
Expected: 从首页点任一指标卡进入详情页；顶部标题为指标中文名；近 7 天/近 30 天可切换，柱状图数量随之变化（7 根 / 30 根）；**睡眠详情额外显示分期卡片**（深睡/浅睡/清醒分段条与图例、入睡/起床时间），其他指标不显示；返回键回到首页。
- [ ] **Step 6: Commit**
```bash
git add -A && git commit -m "feat: 实现指标详情子页（周/月切换 + 趋势图）"
```

### Task 13: 后端 API 仓库骨架（M0）
**Files:**
- Create: `repos/ring-health-api/README.md`, `.gitignore`, `docs/api-contract.md`
**Interfaces:**
- Consumes: 无
- Produces: 一个含接口契约草稿的空仓库，供 M4 使用。
- [ ] **Step 1: 创建目录与 `README.md`**
```bash
mkdir -p /d/cherry/repos/ring-health-api/docs
```
`repos/ring-health-api/README.md`:
```markdown
# ring-health-api
智能戒指健康 App 的后端 API（阶段一仅契约，未实现）。
- 当前状态：**空仓库 + 接口契约草稿**
- 后端技术栈：待 M4 前确定（Spring Boot / .NET 均可，见设计文档）
- 接口契约：见 `docs/api-contract.md`
等待 App 端数据模型稳定后（M3 结束）再启动实现，避免两端空转。
```
- [ ] **Step 2: 写 `.gitignore`**
```gitignore
# 通用
.idea/
.vscode/
*.log
.DS_Store
# Java / Kotlin
*.class
build/
.gradle/
out/
target/
# .NET
bin/
obj/
*.user
```
- [ ] **Step 3: 写 `docs/api-contract.md`**
```markdown
# 接口契约草稿（未实现）
> 阶段一仅用于对齐前后端边界，字段可能随 App 数据模型调整。
## 通用约定
- 基础路径：`/api/v1`
- 认证：`Authorization: Bearer <token>`
- 时间戳：毫秒（UTC）
- 分页：`page`（从 1 开始）、`pageSize`，按时间**倒序**
## 1. 登录
`POST /api/v1/auth/login`
| 字段 | 类型 | 说明 |
|---|---|---|
| phone | string | 手机号 |
| code | string | 短信验证码 |
响应：`{ "token": "...", "userId": "..." }`
## 2. 设备绑定
`POST /api/v1/devices/bind`
| 字段 | 类型 | 说明 |
|---|---|---|
| mac | string | 戒指 MAC 地址（广播数据第 6 位起） |
| name | string | 设备名称 |
| firmwareVersion | string | 固件版本 |
## 3. 健康数据上报
`POST /api/v1/health/records`
| 字段 | 类型 | 说明 |
|---|---|---|
| type | string | `STEP` / `HEART_RATE` / `SLEEP` / `BLOOD_OXYGEN` / `STRESS` / `TEMPERATURE` / `BLOOD_PRESSURE` |
| timestamp | long | 采集时间（毫秒） |
| value | double | 数值 |
支持批量：`POST /api/v1/health/records/batch`，请求体为数组。
## 4. 健康数据查询
`GET /api/v1/health/records?type=STEP&from=<ms>&to=<ms>&page=1&pageSize=100`
响应：
```json
{
"code": 0,
"message": "ok",
"data": { "total": 128, "items": [ { "timestamp": 1757000000000, "value": 8426.0 } ] }
}
```
## 5. 待定项
- 用户资料、头像上传
- 运动记录同步（字段见 App 端 `WorkoutRecord`）
- 固件 OTA 包的托管方式（当前厂商走独立 HTTP 地址）
```
- [ ] **Step 4: 初始化并推送**
```bash
cd /d/cherry/repos/ring-health-api
git init -b main
git add -A
git commit -m "docs: 初始化 API 仓库骨架与接口契约草稿"
git remote add origin http://120.192.101.56:3000/cuiluzheng/ring-health-api.git
git push -u origin main
```
Expected: 推送成功。
---
### Task 14: 端到端验收与文档收尾
**Files:**
- Modify: `repos/ring-health-app/README.md`（补充截图/页面清单）
- Modify: `docs/superpowers/specs/2026-09-10-ring-health-app-design.md`（如有实现偏差）
- Create: `repos/ring-health-app/docs/verification-m1.md`
**Interfaces:**
- Consumes: 前 13 个任务的全部产出
- Produces: 可交付的 M1 静态 App + 验收记录。
- [ ] **Step 1: 全量单元测试**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew :app:testDebugUnitTest
```
Expected: 全部通过（Formatters 7 项 + MockDataProvider 5 项 + HomeViewModel 1 项）。
- [ ] **Step 2: 干净构建**
```bash
cd /d/cherry/repos/ring-health-app && ./gradlew clean assembleDebug
```
Expected: `BUILD SUCCESSFUL`，生成 `app/build/outputs/apk/debug/app-debug.apk`。
- [ ] **Step 3: 真机/模拟器人工验收（逐项打勾）**
> **本步在本机当前状态下无法执行（ledger Ruling R21）。** 本机没有任何模拟器镜像，也没有连接真机
> （Android SDK 只装了 `platform-tools` / `platforms;android-36` / `build-tools;36.1.0`）。
> 因此下面这份清单**要交给人在有设备时执行**，不要由 agent 尝试 `installDebug`、
> 也不要临时去下模拟器镜像（约 1–2 GB）。执行 agent 在本步的动作是：
> 把清单原样抄进验收报告，明确标注「未执行 —— 无设备」，然后继续 Step 4。
> 本条是**已知且有意的覆盖缺口**，不要在其他任何地方把它当成已通过。
在设备上逐项确认：
- [ ] 应用启动无崩溃，底部四个 Tab 显示为 健康 / 运动 / 设备 / 我的
- [ ] 四个 Tab 可自由切换，切换后状态保留、无闪烁
- [ ] **重按已高亮的父 Tab 的行为**（Task 7 用 `popUpTo(start){saveState}` + `restoreState` 实现，
推测会**恢复到该 Tab 保存的子页栈**，即停在子页而不是回到 Tab 根 —— 请实测并记录实际行为）。
若实测是「停在子页」而产品希望「回到根」，那是一个独立的小改动，记下来即可，不算本任务失败
- [ ] 每个页面的 `@Preview` 能在 Android Studio 中正常渲染（R26；这是没有设备时唯一的界面检查手段）
- [ ] 次要文字的灰度一致：同一屏内不应出现深浅两种灰（`TextSecondary` #8E8E93
与 Material 默认 `onSurfaceVariant` #49454F 混用会很明显，R26）
- [ ] 首页：设备状态条显示“RingHealth 智能戒指 · 已连接 / 电量 78%”
- [ ] 首页：步数大环显示 8,426，目标 10,000，环按比例填充
- [ ] 首页：六个指标卡正常显示，**血压显示“未开启”**
- [ ] 首页：点击任一指标卡进入详情页，标题为该指标中文名
- [ ] 详情页：近 7 天显示 7 根柱子，切到近 30 天显示 30 根柱子
- [ ] 睡眠详情额外显示分期卡片（深睡/浅睡/清醒分段条 + 入睡/起床时间），其他指标没有这张卡
- [ ] 详情页：返回后回到首页
- [ ] 运动页：显示“开始运动”卡片 + 5 条运动记录
- [ ] 运动页：“查看全部”进入历史页，底部导航栏仍可见
- [ ] 设备页：戒指卡片显示电量 78%、固件版本 1.0.5
- [ ] 设备页：“更多设置”进入后开关可切换，返回再进入状态保持
- [ ] 我的页：头像卡与两个分组入口正常显示
- [ ] 旋转屏幕/深色系统设置下不崩溃（深色样式不保证，但不得崩溃）
- [ ] **Step 4: 写验收记录 `repos/ring-health-app/docs/verification-m1.md`**
```markdown
# M1 静态页面验收记录
- 验收日期：<填写>
- 构建版本：0.1.0 (versionCode 1)
- 测试设备：<填写机型与 Android 版本>
- 单元测试：`./gradlew :app:testDebugUnitTest` 全绿
- 构建：`./gradlew clean assembleDebug` 成功
## 人工验收结果
| 项 | 结果 | 备注 |
|---|---|---|
| 应用启动无崩溃 | | |
| 四 Tab 切换 | | |
| 首页步数大环 | | |
| 首页指标卡（含血压未开启） | | |
| 详情页周/月切换 | | |
| 运动页与历史页 | | |
| 设备页与开关 | | |
| 我的页 | | |
## 已知限制（阶段一有意为之）
- 数据全部为 Mock，不连蓝牙
- 血压恒为“未开启”占位
- 开关状态不持久化，重启即重置
- 仅浅色模式
```
- [ ] **Step 5: 更新 App `README.md` 页面清单**
在 README 的“当前阶段”下补充：
```markdown
## 页面清单（M1）
| 页面 | 路由 |
|---|---|
| 健康首页 | `home` |
| 运动 | `workout` |
| 运动历史 | `workout/history` |
| 设备 | `device` |
| 设备设置 | `device/settings` |
| 我的 | `profile` |
| 指标详情（步数/心率/睡眠/血氧/压力/体温/血压） | `detail/{metric}` |
```
- [ ] **Step 6: 提交并推送全部仓库**
```bash
cd /d/cherry/repos/ring-health-app && git add -A && git commit -m "docs: 补充 M1 验收记录与页面清单" && git push
cd /d/cherry/docs && git add -A && git commit -m "docs: 补充 M1 实施计划" && git push
```
Expected: 三个仓库（app / api / docs）在 Gitea 上均为最新。

## 备注
**图标依赖回退方案**：若 `material-icons-extended:1.7.8` 与 Compose BOM 2026.09.00 冲突导致构建失败，按此处理：
1. 从 `libs.versions.toml` 移除 `androidx-icons-extended`，从 `app/build.gradle.kts` 移除对应依赖；
2. 新建 `core/designsystem/icon/RingIcons.kt`，用 `ImageVector.Builder` 手绘所需图标（步数/心率/睡眠/血氧/压力/体温/血压/蓝牙/戒指 共 9 个）；
3. 把所有 `Icons.Filled.Xxx` 引用替换为 `RingIcons.Xxx`。
**M2 交接提示**（本计划不实施）：
- 厂商通讯类原样拷贝到 `com.sr.smartring` 包（保持不改）；
- 新增 `data/sdk/SdkHealthDataRepository` 与 `SdkRingDeviceRepository` 实现同名的两个接口；
- 在 `DefaultAppContainer` 中把 Mock 换成 SDK 实现——**这是 M2 唯一需要改动的既有文件**；
- BLE 权限（`BLUETOOTH_SCAN` / `BLUETOOTH_CONNECT` / 位置）在 M2 加入清单与运行时请求。
