+# Infrared Remote Control UI & Multi-Scene Implementation Plan
+
+> **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:** Build a realistic, multi-scene infrared remote control UI (Air Conditioner & Television) with learning/control mode toggle, fixed slot key bindings (1-100), graphic component modeling (circles, capsules, D-pad wheels), and settings navigation.
+
+**Architecture:** Add scene models and predefined key specs in `:android:feature:infrared`. Implement `InfraredRemoteViewModel` to observe Room keys and coordinator actions. Build Compose panels for AC and TV remotes, and integrate the navigation route `infrared_remote/{profileId}` alongside `infrared_settings/{profileId}`.
+
+**Tech Stack:** Kotlin 1.9.24, Jetpack Compose Material 3, Android Gradle Plugin 8.7.3, Room, StateFlow, Hilt, Coroutines.
+
+**Spec:** `docs/superpowers/specs/2026-08-24-infrared-remote-ui-design.md`
+
+## Global Constraints
+
+- Remote buttons display clean symbols/icons, never raw Chinese long names on the button faces.
+- Every button maps to a dedicated 1-100 integer slot (AC: 1–20, TV: 21–50).
+- Learning mode toggle activates visual indicator and switches button clicks from `sendKey` to `learnKey`.
+- Settings navigation allows jumping to the existing `InfraredControlScreen` (renamed to Settings) to view raw entries and device names.
+- Follow TDD with unit and Compose UI tests.
+
+---
+
+### Task 1: Define Remote Scenes and Key Specs
+
+**Files:**
+- Create: `android/feature/infrared/src/main/kotlin/com/flagship/abox/manager/infrared/remote/RemoteModels.kt`
+- Test: `android/feature/infrared/src/test/kotlin/com/flagship/abox/manager/infrared/remote/RemoteModelsTest.kt`
+
+**Interfaces:**
+- Produces: `RemoteScene`, `RemoteButtonId`, `RemoteButtonSpec`, and `RemoteSceneConfig`.
+
+- [ ] **Step 1: Write test for predefined AC and TV remote button specifications**
+
+```kotlin
+package com.flagship.abox.manager.infrared.remote
+
+import org.junit.Assert.assertEquals
+import org.junit.Assert.assertNotNull
+import org.junit.Test

+class RemoteModelsTest {
+    @Test
+    fun acSpecsHaveUniqueSlotsBetween1And20() {
+        val slots = RemoteSceneConfig.AirConditioner.buttons.map { it.defaultSlot }
+        assertEquals(slots.size, slots.distinct().size)
+        assert(slots.all { it.toInt() in 1..20 })
+    }
+
+    @Test
+    fun tvSpecsHaveUniqueSlotsBetween21And50() {
+        val slots = RemoteSceneConfig.Television.buttons.map { it.defaultSlot }
+        assertEquals(slots.size, slots.distinct().size)
+        assert(slots.all { it.toInt() in 21..50 })
+    }
+}

+# 红外学习与发射控制设计
+
+## 1. 背景与目标
+
+本项目当前可用于真实验证的设备包括 ABox 主机、红外控制器、智能插座和温湿度计。本阶段由 moler 负责红外能力，范围聚焦于红外控制器的基础闭环：
+
+1. 在登录成功后的现有页面提供一个临时入口；
+2. 手动配置并记住一个 ABSDK 红外设备名；
+3. 创建并命名多个红外按键；
+4. 通过 ABSDK 发起红外学习；
+5. 保存可重复使用的按键绑定；
+6. 通过 ABSDK 发射已学习按键；
+7. 支持 Fake 和真实 ABSDK 调试模式；
+8. 为后续生活场景保留稳定按键引用。
+
+首版前端只用于功能验证，沿用现有 Compose 和设计系统基础组件，不定义最终产品视觉风格。后续统一视觉改版只替换展示层，不改变红外领域、持久化、应用用例或硬件接口。
+
+## 2. 已确认的 ABSDK 能力边界
+
+ABSDK 0630 提供以下红外公开方法：
+
+```java
+ABRet sendIr(String irDevName, String irKey)
+ABRet studyIrByIrDevName(String irDevName, String irKey)
+ABRet downloadIrCodes(List<IrInfo> irInfos)
+```
+
+现有领域层已将其隔离为 `InfraredGateway`：
+
+```kotlin
+interface InfraredGateway {
+    suspend fun sendKey(
+        profileId: ProviderProfileId,
+        deviceName: DeviceName,
+        key: String,
+    ): DomainResult<Unit>
+
+    suspend fun learnKey(
+        profileId: ProviderProfileId,
+        deviceName: DeviceName,
+        key: String,
+    ): DomainResult<Unit>
+
+    suspend fun downloadCodes(
+        profileId: ProviderProfileId,
+        codes: List<InfraredCode>,
+    ): DomainResult<List<InfraredCodeDownloadResult>>
+}
+```
+
+本设计必须遵守以下事实：
+
+- 学习接口只确认返回成功码和消息，没有已确认的原始红外码返回值；
+- ABSDK 没有公开停止学习方法；
+- ABSDK 没有公开获取学习结果或读取已学习原始码的方法；
+- `downloadIrCodes()` 是把调用方已经拥有的红外码写入主机，不是读取学习结果；
+- ABSDK 没有设备扫描或设备列表接口；
+- 红外方法按 `irDevName + irKey` 寻址；
+- SDK 调用为同步阻塞调用，现有 Bridge 在 `Dispatchers.IO` 上通过全局 `Mutex` 串行执行；
+- SDK 使用固定明文 HTTP 目标，真实接入存在已知传输安全风险。
+
+因此首版保存的是本地按键绑定，而不是原始红外波形或码值：
+
+```text
+ProviderProfileId + DeviceName + sdkKey + displayName + learning status
+```
+
+真实硬件闭环成立的判据是：
+
+```text
+learnKey(deviceName, sdkKey) 成功
+                ↓
+sendKey(deviceName, sdkKey)
+                ↓
+实体被控设备产生正确响应
+```
+
+## 3. 范围
+
+### 3.1 本阶段包含
+
+- 红外功能的领域模型和本地持久化端口；
+- Room 数据库、DAO 和 Repository；
+- 学习、重试、发射、删除和恢复应用用例；
+- 红外 ViewModel 和简单 Compose 页面；
+- 登录成功页面的临时红外入口；
+- 手动输入并记住一个 `irDevName`；
+- 单红外控制器、多按键；
+- Fake/Real ABSDK 显式调试模式；
+- 自动化测试；
+- 真机验收清单；
+- 面向未来生活场景的稳定按键引用。
+
+### 3.2 本阶段不包含
+
+- 最终 UI 视觉规范或复杂遥控器布局；
+- 多个遥控器管理界面；
+- ABSDK 不存在的设备扫描；
+- 原始红外码读取或持久化；
+- 红外码库导入 UI；
+- 硬件停止学习；
+- 完整生活场景模型、规则引擎或场景执行器；
+- Release 中默认启用真实 ABSDK；
+- 绕过或隐藏厂商明文 HTTP 风险；
+- 删除 ABox 服务端已学习按键。
+
+## 4. 架构
+
+采用独立应用编排层，保持现有 `InfraredGateway` 作为纯硬件能力端口：
+
+```text
+登录成功页面
+  └─ 临时入口：红外控制
+        ↓
+InfraredControlScreen
+        ↓
+InfraredControlViewModel
+        ↓
+应用用例
+  ├─ LearnInfraredKey
+  ├─ RetryInfraredKeyLearning
+  ├─ SendInfraredKey
+  ├─ DeleteInfraredKey
+  ├─ RecoverInterruptedInfraredLearning
+  └─ ObserveInfraredKeys
+       ↙                         ↘
+InfraredKeyRepository          InfraredGateway
+       ↓                         ├─ FakeInfraredGateway
+RoomInfraredKeyRepository       └─ AbsdkBridge
+                                      ↓
+                                  ABSDK 0630
+```
+
+### 4.1 边界原则
+
+- `InfraredGateway` 只负责学习、发射和码库下载，不负责 Room、页面状态或遥控器管理；
+- 不修改 `learnKey()` 返回类型，不虚构 ABSDK 原始码结果；
+- 不把 `ABSDK`、`ABRet`、`IrInfo` 或原始 Map 暴露给上层；
+- ViewModel 不直接编排数据库和硬件之间的一致性，统一通过应用用例；
+- Room Entity 不作为领域或 UI 公共模型；
+- Fake 和真实 Bridge 必须共用相同的领域接口和用例；
+- 所有真实 Gateway 接口必须指向同一个进程级 `AbsdkBridge` 实例，保持全局会话和互斥锁一致。
+
+## 5. 数据模型
+
+### 5.1 稳定标识
+
+```kotlin
+@JvmInline
+value class InfraredKeyId(val value: String)
+
+data class InfraredKeyRef(
+    val profileId: ProviderProfileId,
+    val keyId: InfraredKeyId,
+)
+```
+
+`InfraredKeyRef` 是未来生活场景使用的最小稳定引用。场景不应保存显示名、设备名或厂商 Key。
+
+### 5.2 学习状态
+
+```kotlin
+enum class InfraredKeyStatus {
+    LEARNING,
+    READY,
+    FAILED,
+}
+```
+
+状态表示 App 对最近一次学习调用结果的本地记录，不代表设备主动上报的实时状态。
+
+### 5.3 领域模型
+
+```kotlin
+data class SavedInfraredKey(
+    val id: InfraredKeyId,
+    val profileId: ProviderProfileId,
+    val deviceName: DeviceName,
+    val displayName: String,
+    val sdkKey: String,
+    val status: InfraredKeyStatus,
+    val lastErrorCode: String?,
+    val createdAtEpochMillis: Long,
+    val updatedAtEpochMillis: Long,
+)
+```
+
+字段约束：
+
+- `id` 在 App 内稳定，供页面、删除和未来生活场景引用；
+- `profileId` 用于不同登录配置的数据隔离；
+- `deviceName` 是传给 ABSDK 的真实红外设备名；
+- `displayName` 是用户可见名称，可以修改；
+- `sdkKey` 是传给 ABSDK 的稳定 Key，学习后不随显示名改变；
+- `lastErrorCode` 仅保存脱敏厂商错误码，不保存密码、Token、原始 Map 或红外载荷；
+- 时间字段由应用层时钟提供，测试中使用可控时钟。
+
+### 5.4 SDK Key
+
+App 自动生成 SDK Key，不允许用户直接编辑。格式应：
+
+- 仅包含安全 ASCII 字符；
+- 在同一 Provider 和红外设备下唯一；
+- 重试学习时复用；
+- 修改显示名时保持不变；
+- 不直接使用中文、空格或特殊字符。
+
+建议格式：
+
+```text
+app_ir_<normalized-infrared-key-id>
+```
+
+实际长度上限尚未由 ABSDK 文档确认，实现前需选择保守长度，并列入真机验证。
+
+## 6. 本地持久化
+
+采用 Room。Repository 边界至少支持：
+
+```kotlin
+interface InfraredKeyRepository {
+    fun observeKeys(
+        profileId: ProviderProfileId,
+        deviceName: DeviceName,
+    ): Flow<DomainResult<List<SavedInfraredKey>>>
+
+    suspend fun getKey(
+        ref: InfraredKeyRef,
+    ): DomainResult<SavedInfraredKey?>
+
+    suspend fun insertLearningKey(
+        key: SavedInfraredKey,
+    ): DomainResult<Unit>
+
+    suspend fun updateStatus(
+        ref: InfraredKeyRef,
+        status: InfraredKeyStatus,
+        lastErrorCode: String?,
+        updatedAtEpochMillis: Long,
+    ): DomainResult<Unit>
+
+    suspend fun renameKey(
+        ref: InfraredKeyRef,
+        displayName: String,
+        updatedAtEpochMillis: Long,
+    ): DomainResult<Unit>
+
+    suspend fun deleteKey(
+        ref: InfraredKeyRef,
+    ): DomainResult<Unit>
+
+    suspend fun findInterruptedLearning(
+        profileId: ProviderProfileId,
+    ): DomainResult<List<SavedInfraredKey>>
+}
+```
+
+具体签名可在实施计划中按项目既有风格调整，但必须保持职责和语义。
+
+### 6.1 数据库约束
+
+- 主键：`InfraredKeyId`；
+- 索引：`ProviderProfileId + DeviceName`；
+- 唯一约束：`ProviderProfileId + DeviceName + sdkKey`；
+- 查询和删除必须包含 Provider 隔离；
+- 不保存原始红外码；
+- 不把 Room Entity 暴露给领域层；
+- 首版预留 schema version 和迁移测试基础。
+
+### 6.2 单设备策略
+
+页面记住一个当前 `irDevName`，并只展示该设备下的按键。切换当前设备名不会迁移或重写旧按键；旧按键仍绑定学习时使用的设备名。
+
+设备名可以保存到 Room 配置表或 DataStore。若采用 DataStore，只用于当前设备名和 debug 模式等轻量配置，不承载红外按键集合。
+
+## 7. 学习流程
+
+`LearnInfraredKey` 的流程：
+
+1. 验证用户已登录且存在有效 `ProviderProfileId`；
+2. 验证 `deviceName` 和 `displayName` 非空；
+3. 生成稳定 `InfraredKeyId` 和 `sdkKey`；
+4. 先写入状态为 `LEARNING` 的记录；
+5. 在应用级协程作用域调用 `InfraredGateway.learnKey()`；
+6. 成功时更新为 `READY` 并清空错误码；
+7. 失败时更新为 `FAILED` 并保存脱敏错误码；
+8. 如果状态更新失败，记录可恢复的本地数据错误，但不重新生成 SDK Key；
+9. 页面通过 Room Flow 观察最终状态。
+
+### 7.1 重试
+
+重试必须：
+
+- 使用原 `InfraredKeyId`；
+- 使用原 `sdkKey`；
+- 先将状态更新为 `LEARNING`；
+- 再调用 ABSDK；
+- 不创建重复按键记录。
+
+### 7.2 页面离开
+
+学习调用开始后，页面可以退出。任务继续在应用级作用域等待 SDK 返回，并更新 Room。ViewModel 销毁不应直接取消已经提交的学习编排。
+
+这不是后台系统任务保证：如果进程被系统杀死，底层同步网络请求及设备状态无法可靠恢复。
+
+### 7.3 进程恢复
+
+App 启动或登录恢复后，查找遗留的 `LEARNING` 记录：
+
+```text
+LEARNING → FAILED
+错误提示：上次学习结果未确认，请重新学习
+```
+
+不得自动标记为 `READY`，也不得自动发射来试探设备状态。
+
+### 7.4 取消语义
+
+ABSDK 没有停止学习 API。首版 UI 不提供或宣称“停止硬件学习”。用户可以离开页面，但学习调用仍等待成功、失败或 SDK 超时。
+
+## 8. 发射流程
+
+`SendInfraredKey` 的流程：
+
+1. 使用 `InfraredKeyRef` 查询本地记录；
+2. 记录不存在时返回领域错误；
+3. 仅允许 `READY` 状态发射；
+4. 取得记录中的 `profileId + deviceName + sdkKey`；
+5. 调用 `InfraredGateway.sendKey()`；
+6. 成功时向 UI 返回一次性成功事件；
+7. 失败时保留按键 `READY` 状态，仅报告本次错误；
+8. 不自动重试，避免重复操作电视、空调等实体设备。
+
+未来生活场景通过稳定 `InfraredKeyRef` 调用同一发送用例或薄执行器：
+
+```kotlin
+interface InfraredActionExecutor {
+    suspend fun execute(ref: InfraredKeyRef): DomainResult<Unit>
+}
+```
+
+本阶段只定义或保证稳定引用边界，不实现 Scene 模型、规则引擎或场景执行顺序。
+
+## 9. 删除与重命名
+
+### 9.1 删除
+
+- `FAILED` 和 `READY` 记录可以删除；
+- `LEARNING` 中不允许删除，避免后台结果写入已不存在的记录；
+- 删除只移除本地引用；
+- ABSDK 没有删除服务端红外 Key 的公开接口；
+- UI 必须提示“ABox 服务端可能仍保留该按键”；
+- 删除后未来场景引用解析失败，不再发射。
+
+### 9.2 重命名
+
+- 只修改 `displayName`；
+- 不修改 `id`、`deviceName` 或 `sdkKey`；
+- 重命名后学习和发射能力保持不变；
+- 场景引用保持有效。
+
+## 10. Android 前端
+
+### 10.1 临时入口
+
+在当前登录成功后的页面添加“红外控制”按钮，导航到独立 `InfraredControlScreen`。未来正式信息架构完成后只迁移入口。
+
+### 10.2 页面内容
+
+首版页面只包含：
+
+- 返回按钮和标题；
+- 当前数据源标识：Fake 或真实 ABox；
+- 红外控制器设备名输入和保存；
+- 已学习按键列表；
+- 学习新按键按钮；
+- 按键状态；
+- READY 按键的发射按钮；
+- FAILED 按键的重试按钮；
+- 删除入口和确认提示；
+- 基础错误反馈。
+
+不加入复杂遥控器模板、图标系统、网格布局、品牌色或动画规范。
+
+### 10.3 设备名
+
+- ABSDK 没有设备扫描能力；
+- 首次进入时手动填写 `irDevName`；
+- 保存后本地记住；
+- 没有设备名时禁止学习；
+- 修改设备名前提示旧按键仍绑定旧设备；
+- 列表只显示当前设备名下的按键。
+
+### 10.4 学习交互
+
+用户输入显示名称后开始学习。页面提示：
+
+```text
+请将实体遥控器对准红外控制器并按下目标按键。
+```
+
+按键显示 `LEARNING`、`READY` 或 `FAILED`。允许离开页面，但不显示“停止硬件学习”。
+
+### 10.5 发射交互
+
+- 只有 `READY` 按键可发射；
+- 发射期间禁用该按键，防止重复点击；
+- 成功显示短暂提示；
+- 失败显示具体错误；
+- 不自动重试；
+- 单次失败不删除或降级按键状态。
+
+### 10.6 删除提示
+
+删除确认文案应明确：
+
+```text
+仅从本机列表移除，ABox 服务端可能仍保留该按键。
+```
+
+## 11. Debug Fake/Real 路由
+
+Debug 构建提供显式运行模式：
+
+- `FAKE`：页面开发、自动化测试和错误模拟；
+- `REAL_ABSDK`：复用当前登录会话，调用真实 `AbsdkBridge`。
+
+约束：
+
+- 页面持续显示当前模式；
+- 不允许在学习任务进行中切换模式；
+- Fake 和 Real 共用同一 ViewModel、应用用例和 Room Repository；
+- 模式和 Provider 数据必须隔离，避免 Fake 按键误用于真实设备；
+- Fake 支持按 `ProviderProfileId + DeviceName + sdkKey` 配置成功或失败；
+- 真实模式的所有 Gateway 接口绑定同一 `AbsdkBridge` 单例；
+- 真实模式必须显式 opt in `CleartextAbsdkTransport`；
+- Release 暂不启用真实 Bridge，除非项目明确批准传输安全方案。
+
+真实 App 接入还必须补齐：
+
+- `:absdk-bridge` 依赖；
+- Hilt 绑定；
+- `INTERNET` 权限；
+- 经批准的明文网络配置；
+- 登录会话与红外 Gateway 的同一 Bridge 实例；
+- Token 失效后的页面返回登录流程。
+
+## 12. 错误处理
+
+继续使用现有 `DomainResult` 和 `DomainError`。不为首版扩充 sealed 类型，优先利用已有分类和 `externalCode`。
+
+| 情况 | UI 反馈 | 本地状态 |
+|---|---|---|
+| Token 无效 | 登录已失效，返回登录 | 学习按键为 FAILED；发射按键仍为 READY |
+| 红外设备不存在 | 检查设备名 | 学习按键为 FAILED |
+| 红外设备离线 | 检查供电和网络 | 学习按键为 FAILED；发射按键仍为 READY |
+| KEY/码值不存在 | 建议重新学习 | 发射按键仍为 READY，由用户决定重学 |
+| 红外发射失败 | 显示失败，可手动重试 | READY |
+| 网络超时 | 网络或 ABox 服务不可用 | 学习按键为 FAILED；发射按键仍为 READY |
+| 本地保存失败 | 无法开始学习 | 不调用硬件学习 |
+| 学习成功但最终状态写入失败 | 显示数据保存异常并保留恢复信息 | 不生成新 sdkKey |
+| 未知错误 | 通用提示及脱敏错误码 | 按操作类型处理 |
+
+日志不得包含：
+
+- 用户密码；
+- Token；
+- 原始 SDK Map；
+- 原始红外码或载荷；
+- 可用于重放的敏感字段。
+
+## 13. 自动化测试
+

+覆盖：
+
+1. 学习前先保存 `LEARNING`；
+2. 学习成功更新为 `READY`；
+3. 学习失败更新为 `FAILED`；
+4. 重试复用原 `sdkKey`；
+5. 修改显示名不改变 `sdkKey`；
+6. 只有 `READY` 可以发射；
+7. 发射使用保存的 `deviceName + sdkKey`；
+8. 不同 Provider 数据隔离；
+9. 遗留 `LEARNING` 恢复为 `FAILED`；
+10. 删除后稳定引用失效；
+11. ViewModel 销毁后应用级学习任务仍可落库；
+12. 发射失败不改变 READY；
+13. 进行中的学习阻止运行模式切换。
+
+### 13.2 Room

+- 创建学习任务；
+- 显示学习中、成功和失败；
+- 重试学习；
+- 点击发射并防重复点击；
+- 删除确认；
+- Fake/Real 模式标识；
+- 登录失效引导；
+- 基本中文和英文资源。
+
+## 14. 真机验收
+
+第一轮使用现有 ABox 主机和红外控制器：
+
+1. 登录真实账号；
+2. 输入后台提供的准确 `irDevName`；
+3. 创建唯一按键，例如“测试电源”；
+4. 调用学习并记录耗时、返回码和消息；
+5. 学习成功后立即发射；
+6. 验证实体电器是否响应；
+7. 用同一按键重复发射；
+8. 重新学习同一 `sdkKey`，验证覆盖或报错行为；
+9. 红外控制器断电后验证离线错误；
+10. 不按实体遥控器，验证实际超时行为；
+11. 页面退出后验证后台结果落库；
+12. 进程被杀后验证遗留 LEARNING 恢复；
+13. Token 失效后验证返回登录；
+14. 记录 SDK 是否存在未文档化 `dicDatas`，但不将内容写入生产日志。
+
+### 14.1 必须验证的未知项
+
+- 学习调用是立即返回还是阻塞到捕获完成；
+- 学习成功是否自动绑定 `sdkKey`；
+- 同一 `sdkKey` 重学是否覆盖；
+- 无信号时实际超时时间；
+- 页面离开后底层调用是否可完成；
+- 设备名格式、大小写和特殊字符规则；
+- 服务端是否永久保留已学习 Key；
+- SDK 是否返回未文档化数据；
+- `sdkKey` 的长度限制；
+- 真实模式所需初始化信息和调用顺序。
+
+这些未知项不得通过业务层假设隐藏。真机结果应更新协议文档和后续设计。
+
+## 15. 验收标准
+
+本阶段完成需要满足：
+
+- 登录成功页面可以进入简单红外页面；
+- 可以手动配置并恢复一个红外设备名；
+- 可以创建多个命名按键；
+- 学习调用前已持久化 LEARNING；
+- 学习成功或失败能正确落库；
+- READY 按键可以调用发射；
+- 显示名修改不影响发射；
+- Fake 模式可以覆盖主要状态和错误；
+- Real 模式明确标识并调用真实 Bridge；
+- 页面退出后学习任务仍可更新状态；
+- 进程中断后遗留学习状态可以保守恢复；
+- 自动化测试通过；
+- 真机至少完成一次“学习成功 → 发射 → 实体响应”；
+- 未确认硬件语义被记录，不伪装为已支持；
+- 未来生活场景可以通过稳定 `InfraredKeyRef` 引用按键。
+
+## 16. 后续工作
+
+本设计完成后再分别规划：
+
+1. 多遥控器和房间组织；
+2. 统一产品视觉和正式导航入口；
+3. 红外码库导入；
+4. 生活场景编排；
+5. Scene 顺序执行和单项结果；
+6. 厂商明文 HTTP 的正式安全方案；
+7. 真机验证后对学习语义、超时和错误模型的修订。

+# 红外遥控器界面与多场景控制设计规范 / Infrared Remote Control UI Specification
+
+## 1. 背景与目标 (Background & Goals)
+
+在完成了底层红外学习、发射、Room 数据库、1~100 整数 Key 槽位管理以及 Fake/Real ABSDK 路由的基础上，本项目需要提供专业且直观的前端遥控器人机交互界面。
+
+### 核心目标
+1. **多场景遥控面板**：提供空调 (Air Conditioner) 与电视 (Television) 两大经典场景遥控器界面，使用圆形、圆角矩形、胶囊、圆形方向盘等拟物/现代图形组件构建真实遥控器外观。
+2. **学习模式与控制模式切换**：右上角提供“红外学习模式”开关，在控制模式下点击按键发射红外，在学习模式下点击按键录制红外。
+3. **固定槽位绑定 (Fixed Slot Binding)**：遥控器上的每一个功能按键具有预设唯一的 1~100 整数槽位编号（例如空调电源为 Slot 1，电视电源为 Slot 21）。
+4. **简洁的符号化设计**：遥控器按键表面只展示标准图标与简写符号（⏻, +, -, ∧, ∨, ❄, 🔊 等），不展示底层数据库中文长名称。
+5. **设置页面解耦与导航**：原“红外控制页面”定位为“红外学习设置页面”（Infrared Settings），通过遥控器右上角设置图标 ⚙️ 进入，用于配置红外设备名和管理全部已学按键列表。
+
+---
+
+## 2. 槽位与按键分配定义 (Slot & Button Mapping)
+
+每个按键定义为一个 `RemoteButtonSpec`，包含按键唯一标识 `id`、对应默认槽位 `defaultSlot`、默认显示名称 `displayName`、图标及在遥控器面板中的图形位置。

+  - `learnedSlots`: `Map<String, SavedInfraredKey>`（已在 Room 数据库中记录为 READY 的槽位映射）
+  - `savedDeviceName`: `DeviceName?`（当前配置的红外设备名，如 `红外控制器`）
+  - `runtimeMode`: `InfraredRuntimeMode`（Fake 或 Real ABSDK）
+  - `message`: `UiMessage?`（提示信息或错误）
+
+---
+
+## 4. 交互与视觉规范 (Interaction & Visuals)
+
+### 4.1 视觉造型
+1. **遥控器本体外壳 (Remote Body Chassis)**：

+4. **圆形导航方向盘 (D-Pad Wheel)**：
+   - 直径约 `180.dp` 的圆形组合组件，外环包含 4 个扇区方向按键，内嵌独立的圆形 OK 键。
+
+### 4.2 按键状态机反馈
+1. **控制模式 (学习开关 OFF)**：
+   - **已录制 (READY)**：按键实体呈现饱满质感，点击触发波纹反馈，调用 `sendKey` 发射红外，提示“已发射”。
+   - **未录制 (UNLEARNED)**：按键显示浅色未激活状态；点击弹出轻量提示：`“按键尚未学习，请打开右上角学习模式”`。
+2. **学习录制模式 (学习开关 ON)**：
+   - 顶部呈现橙色高亮提示条：`“🔴 学习模式已开启：点击任意按键开始录制”`。
+   - 所有按键进入可录制状态（带提示外框）。
+   - 点击目标按键后：
+     - 按键上显示微型 Loading 光圈。
+     - 调用 `learnKey(deviceName, defaultSlot, displayName)`。
+     - 手机或控制器捕获红外信号成功后，按键变为 READY 并伴随成功提示。
+
+---
+
+## 5. 验证与测试标准 (Verification & Acceptance Criteria)

+
+---
+
+## 3. 标准真机测试流程 (12 项用例) / Standard 12-Step Test Procedure
+
+### 用例 1: 真实会话认证前置 (Authenticate Shared Bridge)
+- **前置**: 通过登录模块对进程单例 `AbsdkBridge` 进行登录认证。
+- **步骤**: 检查进入红外控制页面前，会话 Token 是否有效。
+- **预期**: 若未认证，进入 Real 模式操作时返回 `TokenInvalid` 并提示返回登录。
+
+### 用例 2: 输入并保存真实设备名 (Enter and Save irDevName)
+- **步骤**: 在“红外设备名称”输入框中输入 `红外控制器` 或后台分配的真实设备名，点击“保存设备名”。
+- **预期**: 本地 Room 保存成功，页面显示“已保存设备：红外控制器”，启用“学习新按键”入口。
+
+### 用例 3: 学习全新唯一按键 (Learn Unique Key)
+- **步骤**: 点击“学习新按键”，输入显示名称（如“空调开”），点击“开始学习”；将物理遥控器对准红外控制器按下按键。
+- **预期**: 本地先写入 `LEARNING` 状态，硬件捕获完成后状态自动刷新为 `READY`，记录响应耗时与返回码。
+
+### 用例 4: 立即发射已学习按键 (Send Learned Key Immediately)
+- **步骤**: 学习成功后，点击该按键右侧的“发射”按钮。
+- **预期**: ABSDK 返回 `00000`，实体电器执行对应操作，发射期间按钮防重复点击。
+
+### 用例 5: 重复发射验证稳定性 (Repeat Send)
+- **步骤**: 间隔 3 秒再次点击同一按键的“发射”按钮。
+- **预期**: 发射稳定成功，电器再次响应，按键保持 `READY` 状态不变。
+
+### 用例 6: 重新学习同一 SDK Key (Relearn Same Key)
+- **步骤**: 针对已存在或失败的按键点击“重试”/重新学习。
+- **预期**: 复用相同的 `InfraredKeyId` 和 `sdkKey`，先变更为 `LEARNING`，学习完成后恢复 `READY`，不生成冗余记录。
+
+### 用例 7: 控制器断电/离线测试 (Controller Offline)
+- **步骤**: 拔掉红外控制器电源，发起学习或发射。
+- **预期**: ABSDK 返回 `20206`，领域层转换为 `DomainError.DeviceOffline`，学习按键标为 `FAILED`，UI 提示控制器离线。
+
+### 用例 8: 遥控器无信号/超时测试 (No Signal / Learning Timeout)
+- **步骤**: 点击“开始学习”，但不按物理遥控器任何按键，等待 SDK 返回。
+- **预期**: 记录实际超时等待时间与错误码（如 `20204`/`20205`），按键转换为 `FAILED` 并允许重试。
+
+### 用例 9: 学习过程中离开页面 (Leave Page During Learning)
+- **步骤**: 点击开始学习后，立即点击“返回”离开红外页面；稍后重新进入。
+- **预期**: Application 协程作用域内任务继续执行，学习完成后 Room 数据库正确持久化结果，重新进入显示最新状态。
+
+### 用例 10: 进程被杀死后状态恢复 (Process Interruption Recovery)
+- **步骤**: 在 `LEARNING` 状态下强制杀死 App 进程并重启。
+- **预期**: App 启动或重新进入页面时，`RecoverInterruptedInfraredLearning` 将遗留的 `LEARNING` 保守恢复为 `FAILED`，提示用户重新学习。
+
+### 用例 11: Token 失效与重新登录 (Token Expiration)
+- **步骤**: 主机端使 Token 失效或超过 2 小时后发起红外操作。
+- **预期**: 返回 `TokenInvalid`，本地会话被清除，页面提示登录失效并导航返回。
+
+### 用例 12: 检查未文档化响应字段 (Inspect Undocumented Fields)
+- **步骤**: 在调试构建中检查 `ABRet.getDicDatas()` 是否包含未文档化字段。
+- **安全约束**: 严禁将 Raw Payload、Token、密码或未脱敏数据打印至生产日志。
+
+---
+
+## 4. 协议与硬件事实确认记录 / Observed Facts
+
+- **SDK 阻塞模式**: 同步阻塞 HTTP POST 调用，由 `AbsdkBridge` 调度至 `Dispatchers.IO` 并通过进程级 `Mutex` 串行执行。
+- **数据隔离**: `FAKE` 模式自动使用 `profileId:infrared-fake` 隔离数据，`REAL_ABSDK` 模式使用主会话数据。
+- **安全门禁**: 真实 ABSDK 依赖明文传输，Release 构建中完全禁用硬件接口并由 `InfraredReleaseModule` 安全阻断。
