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: ..."
  ],

    "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. 人员活动规律性分析：日志记录了从21:55到23:38的活动，涉及卧室、玄关、客厅和厨房的运动传感器触发。这种多房间、分散且持续的人员移动符合独居老人在晚间进行洗漱（卫生间）、休息前准备或观看电视等日常活动的特征。",
    "2. 卫生间使用模式正常：卫生间运动传感器在22:10、22:40、23:10分别出现Occupancy=0（离开）的状态，间隔约30分钟。这表明住户多次进入并离开卫生间，每次停留时间合理，没有长时间滞留（可能跌倒）或长时间无响应（可能昏迷）的迹象。",
    "3. 环境数据稳定：各房间温度传感器读数在正常范围内波动（卧室~21.4-21.6°C，客厅/厨房~22.4-22.7°C），数值变化平缓，无剧烈跳变，表明传感器工作正常且室内环境舒适，无火灾或极端天气导致的异常升温。",
    "4. 无入侵迹象：入户门传感器仅在玄关运动传感器触发时伴随活动，但日志中未记录门锁状态变更（如开锁失败、非法开启）或窗户传感器的异常触发。所有活动均发生在室内已知区域，符合住户在家行为。"
  ],
  "key_evidence": [
    "卫生间运动传感器在22:10, 22:40, 23:10多次变为0（离开），显示正常的如厕/洗漱循环。",
    "卧室、玄关、客厅、厨房运动传感器在晚间时段有规律的交替触发，符合居家生活轨迹。",
    "全屋温度传感器读数稳定，无异常高温或剧烈波动。",
    "无门锁异常操作或烟雾/一氧化碳报警触发。"
  ],
  "recommended_actions": [
    "无需立即干预，继续保持常规监控。",
    "建议确认住户对当前的自动化场景（如夜间灯光联动）感到舒适，如有需要可微调灵敏度以减少误报。"

Rejected response:

## 任务
以下是过去一段时间的设备活动记录。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",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [

    "关键证据1",
    "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。

    "2. 分析人员活动模式：运动传感器（Occupancy Sensor）在多个房间（entrance, kitchen, bedroom, living_room）间歇性触发，且卫生间传感器有短暂的离开信号（Occupancy=0）。这种多房间、非持续性的移动符合老人在夜间起夜、喝水或查看时间的正常行为特征，未发现长时间静止（可能跌倒）或异常剧烈的连续移动。",
    "3. 分析环境参数：温度传感器读数稳定在 21°C - 22.7°C 之间，波动范围极小（<1°C），表明空调或供暖系统运行正常，无火灾导致的温度骤升或设备故障导致的极端温差。",
    "4. 排除其他风险：日志中未出现烟雾报警器、一氧化碳报警器、漏水传感器或门锁状态的异常事件，因此排除火灾、燃气泄漏、水浸和入侵风险。"
  ],
  "key_evidence": [
    "时间段 22:15-23:50 内，各房间运动传感器呈现间歇性激活状态，符合夜间正常起居规律。",

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。

## 任务
监控系统标记了潜在异常。请分析下面的日志，判断是否需要采取响应措施，并给出建议。

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。

    "1. 分析入户门事件：在 22:27:18 至 22:27:19 期间，记录到入户门传感器状态变为 True（通常表示门被打开或处于非闭合状态），紧接着门锁执行了 Manual 锁定操作并确认 LockState=1。这符合住户回家开门后重新锁门，或者离家时锁门的正常行为逻辑。由于随后没有持续的非法入侵迹象（如多个运动传感器同时触发且无对应住户ID，或深夜频繁异常开锁），此行为视为正常。",
    "2. 分析设备控制与人员移动：22:27:03 客厅灯和空调被关闭，同时玄关、餐厅、客厅、主卧等区域运动传感器相继触发。这表明有人从客厅区域离开，可能前往卧室或门口。这种‘关灯关空调’伴随‘多区域运动检测’的模式是典型的睡前准备或离家前的正常行为习惯。",
    "3. 分析后续活动模式：22:45 至 23:07 期间，儿童房、主卧、客厅等区域反复出现 Occupancy=1 的信号，且伴有卫生间（22:59）和次卧（23:00）的 Occupancy=0 信号。这反映了家庭成员在夜间的正常走动（如去洗手间、查看孩子、整理物品等）。所有动作均在合理的时间窗口内，没有出现长时间无人却触发警报，或异常时间段的异常聚集，因此判定为正常生活轨迹。"

## 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:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示为独居老人在晚间（21:55-23:39）的正常居家活动，无安全威胁或异常行为。",
  "reasoning": [
    "1. 活动模式分析：日志涵盖了从21:55到23:39的时间段，期间卧室、客厅、玄关和厨房的运动传感器多次触发（Occupancy=1），且卫生间传感器有间歇性触发后归零（Occupancy=0）。这符合老人睡前在客厅休息、偶尔去卫生间、最后回卧室就寝的典型夜间活动轨迹。",
    "2. 设备状态一致性：所有涉及的人员存在传感器均报告了合理的占用状态变化，没有发现长时间静止不动（可能跌倒）或完全无活动的情况。卫生间传感器的周期性清零表明有人进出使用，而非传感器故障。",
    "3. 环境参数正常：各房间温度读数在合理范围内（卧室约21.4-21.6°C，客厅/厨房约22.4-22.7°C），且随时间波动极小，未出现火灾或设备过热导致的温度骤升。未发现烟雾报警器或一氧化碳报警器的触发记录。",
    "4. 排除入侵风险：入户门传感器和门锁在日志片段中未显示异常开启或非法解锁事件，且运动传感器的活跃区域主要集中在室内生活区，未见非授权进入迹象。"
  ],
  "key_evidence": [
    "卧室、客厅、厨房运动传感器在21:55至23:39期间多次检测到人员活动（Occupancy=1），符合夜间居家规律。",
    "卫生间运动传感器在22:14、22:44、23:14出现 Occupancy=0，表明有人短暂使用后离开，属正常生理需求活动。",
    "全屋温度数据稳定，无剧烈波动，且无烟雾/燃气报警触发。",
    "无入户门锁异常操作或门窗非法开启记录。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续监控夜间活动模式，若未来出现长时间无活动或异常时间段的活动，再行排查。"
  ]
}
```

Rejected response:
{
