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
请综合以下多个设备与环境状态，评估家庭整体安全状况，指出任何潜在风险。

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",

  ],
  "recommended_actions": [

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。

## 任务
以下是过去 3 天的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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",

  ],
  "recommended_actions": [

}
```

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。

    "推理步骤 2: 检查环境传感器数据。温度传感器读数（如 living_room_temp_sensor 的 2549 mK ≈ 25.5°C）处于舒适且安全的范围内，未出现高温报警或低温异常；烟雾报警器未在日志中触发警报事件。",
    "推理步骤 3: 验证设备状态一致性。厨房灶具 (cook_surface) 仅在白天有人活动时开启，随后关闭；门窗传感器和窗帘状态变化与人员进出及开窗行为逻辑一致，未发现门锁被非法操作或传感器卡死导致的误报/漏报现象。"

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。

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。

请按以下 JSON 格式回答：

  "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",

## 任务
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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",

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

}
```

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。

    "环境参数正常：温度传感器读数（如客厅约 25°C，卧室约 23-24°C）处于舒适且安全的范围内，未出现高温预警或传感器漂移导致的数值突变；厨房灶具虽被占用，但伴随的是正常的烹饪灯光开启和温度变化，无持续高温或烟雾报警触发。",
    "设备状态健康：所有运动传感器、门窗接触传感器和漏水传感器的状态切换逻辑连贯（例如进入房间灯亮/人检测到，离开后状态复位），无任何卡死、误报或数据丢失现象；入户门锁在日志中未显示异常开启事件。"

    "温度传感器数值随季节和昼夜自然波动，无超出正常范围的极端值或跳变。",

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。

## 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。

Chosen response:

  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "health_concern",
  "threat_description": "做饭时间异常短",
  "reasoning": [
    "推理步骤1: 做饭时长明显缩短",

    "推理步骤3: 可能提示进食不足或功能下降"
  ],

Rejected response:
```json
{
  "is_anomaly": false,

  "threat_description": "日志显示独居老人正常的日间活动模式，包括规律的就餐烹饪、多房间移动及环境参数稳定，未发现安全威胁。",
  "reasoning": [
    "时间逻辑合理：厨房灶具 (kitchen_cook_surface) 的开启与关闭事件（如 12:00-12:05）均发生在有人员在场（kitchen_occupancy=1）且温度传感器读数正常的时间段内，符合正常烹饪行为，无长时间无人看管风险。",
    "环境数据一致：所有温度传感器（living_room, kitchen, bedroom）的数值均在合理范围内（约 24.3°C - 25.6°C），且随时间推移呈现自然的昼夜变化趋势，无异常高温或低温漂移迹象。",
    "活动轨迹连贯：运动传感器（occupancy_sensor）在客厅、卧室、玄关等区域频繁触发，表明住户处于活跃状态，且各房间 occupancy 状态切换自然，不存在长时间静止不动或异常徘徊导致的跌倒/健康隐患。"
  ],
  "key_evidence": [
    "2026-08-29T12:00:00 至 12:05:00 期间，厨房灶具开启仅持续 5 分钟即关闭，且全程伴随厨房有人检测信号。",
    "全天温度传感器读数稳定在 24°C-26°C 区间，未出现超出正常生活环境的极端值。",
    "多个房间（living_room, bedroom, entrance）的运动传感器在白天时段持续报告 Occupancy=1，证明住户活动正常。"
  ],
  "recommended_actions": [
    "继续保持当前设备监控策略，无需额外干预。",
    "建议定期查看烟雾报警器和漏水传感器的自检状态，确保硬件功能正常。"
