你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

    "2. 排除误报（Fire Risk）：虽然烟雾报警器处于“测试中”状态，但同一时间段内（08:00-08:05），厨房温度传感器读数稳定在 2524-2541 (单位通常为 0.01°C，即约 25.2-25.4°C)，没有任何异常升温迹象。此外，日志中未出现 `SmokeCoAlarm.AlarmState` 触发报警的记录，仅记录了测试状态。",
    "3. 结合上下文分析：此时段为早晨 8 点，入户门传感器显示有人进出（Entrance occupancy=1, Door Lock 操作），符合居民日常活动规律。温度数据平稳，无剧烈波动，排除了传感器故障或环境异常导致误触发的可能。",
    "4. 结论：该事件是智能家居设备正常的周期性自检行为，非安全威胁。"

你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

    "2. 排除误报干扰：自检期间（08:00-08:05），其他传感器如温度传感器读数正常波动（2522-2549之间），且运动传感器持续报告无人状态（Occupancy=0），没有伴随异常的环境突变（如温度骤升、烟雾浓度激增等）。",
    "3. 确认行为合理性：早晨 07:29 左右有门锁操作和灯光开关记录，符合住户早起活动的特征；随后的长时间无活动（Occupancy=0）与住户可能离开厨房或房间休息/洗漱的行为一致，结合烟雾报警器的自检完成，整体场景逻辑自洽，无入侵、火灾或设备故障迹象。"
  ],
  "key_evidence": [
    "kitchen_smoke_alarm | SmokeCoAlarm.TestInProgress = True (08:00) 随后变为 False (08:05)，确认为自检流程。",

    "2. 洗碗机状态分析：洗碗机在 14:00 进入工作状态（OperationalState=1），并在 14:30 设置了 1800秒（30分钟）的倒计时，于 14:55 结束工作（OperationalState=0）。整个流程逻辑连贯，符合标准洗涤程序，未发现异常中断或故障。",

    "推理步骤 2: 在此期间 (12:44)，厨房窗户传感器报告状态为 False (False 通常表示接触断开，即窗户打开)。在烹饪过程中打开窗户会加速热量积聚或导致燃气泄漏扩散至其他区域（如果是燃气灶），增加了火势蔓延的风险，同时也表明用户可能离开厨房去处理其他事务（如洗碗机启动）。",
    "推理步骤 3: 虽然 14:00 启动了洗碗机，但此时灶具早已关闭。核心风险窗口在于 12:04 到 12:44 之间，这是一个典型的‘无人看管烹饪’场景，尤其是结合窗户开启这一异常行为，使得火灾风险等级显著升高。",
    "推理步骤 4: 温度传感器数据显示厨房温度从 25°C 上升至接近 30°C (2919/10 = 29.19°C)，随后因灶具关闭和通风而下降，这符合烹饪加热的物理规律，进一步佐证了烹饪活动确实发生且持续了一段时间。"

System:
你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

    "推理步骤 2: 关键异常点在于紧随其后的温度数据。在灶具关闭后的短时间内 (19:25:00)，厨房温度传感器读数从正常的约 22°C (2284 mK) 瞬间跳变至 28.6°C (2860 mK)，并在 19:35:00 再次出现类似的高值波动 (27.4°C)。虽然绝对温差不大，但结合独居老人背景，这种非线性的剧烈跳变往往指示传感器检测到局部过热或发生了未被烟雾报警器立即捕捉的初期火情/热事件。",

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],
  "key_evidence": [
    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

    "1. 烟雾报警器状态分析：在 08:00:00 至 08:05:00 期间，kitchen_smoke_alarm 的 TestInProgress 属性由 True 变为 False，且 ContaminationState 为 0。这明确表明用户正在执行或刚刚完成一次手动/自动的功能测试（Self-test），而非火灾报警。这是维护设备的正常行为。",
    "2. 温度传感器数据分析：厨房温度传感器（kitchen_temp_sensor）报告的数值范围在 2468-2559 之间。根据 Matter 协议标准，TemperatureMeasurement.MeasuredValue 的单位是厘氏度（cHmdegC，即 0.01°C）。因此，实际温度约为 24.68°C - 25.59°C。该温度范围处于舒适的室内环境温度区间，且变化平缓，符合夏季早晨室温特征，无过热或传感器故障迹象。",
    "3. 其他设备活动分析：入户门锁在 07:16 左右有解锁和上锁的操作记录，伴随门磁状态变化，符合住户出门或回家的正常逻辑。运动传感器和灯光开关也呈现规律性的启停，未发现长时间无人却亮灯、或异常入侵的迹象。"
