## 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",

## 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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "放学后长期只有浴室活动",
  "reasoning": [
    "推理步骤1: 放学后长时间只有浴室相关信号",
    "推理步骤2: 缺少回到儿童房或公共区域的链路",
    "推理步骤3: 存在异常风险"
  ],
  "key_evidence": [
    "放学后长时间只有浴室相关信号",
    "缺少回到儿童房或公共区域的链路",
    "存在异常风险"
  ],
  "recommended_actions": [
    "标记为儿童异常停留风险，建议人工确认安全。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示家庭处于正常的晚间活动状态，无入侵、设备故障或环境安全隐患。",
  "reasoning": [
    "时间线分析：事件发生在下午 14:30 至 18:00 之间，符合典型的家庭日间/傍晚活动时间段。",
    "人员分布逻辑合理：儿童房 (kids_room) 和餐厅 (dining_room) 有持续的人员活动记录，而客厅 (living_room) 在部分时段无人，符合家庭成员在不同房间活动的正常模式。",
    "温度数据正常：所有温度传感器读数（约 23-24°C）均在舒适且安全的范围内，未出现异常高温（火灾风险）或低温（设备故障），且数值随时间自然波动，无漂移或卡死现象。",
    "门锁与安防状态正常：入户门在 16:07 被手动上锁，随后接触传感器显示关闭状态；期间虽有人员进出玄关 (entrance_occupancy)，但未检测到非法闯入或未授权开门行为。",
    "次卫灯光逻辑：次卫灯 (second_bathroom_light) 的开启时间与主卧室 (master_bedroom) 有人活动的时间高度重合，推测为家庭成员使用卫生间后的正常照明操作，非异常触发。"
  ],
  "key_evidence": [
    "16:07 front_door_lock 执行手动上锁操作，且随后 contact_sensor 显示门已关闭。",
    "全时段温度传感器读数稳定在 23°C-24°C 区间，无极端值或突变。",
    "kids_room 和 dining_room 的 occupancy 传感器持续报告有人 (1)，表明家庭内部活动正常。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续保持当前的设备监控频率，定期校准运动传感器以确保准确性。"
  ]
}

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",

    "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。

    "行为逻辑一致性：次卫灯光（second_bathroom_light）的开启时间与主卫/主卧 occupancy 状态存在合理的关联（如 16:30 开启时主卫无人，可能是清洁或准备使用），属于正常的家庭内部活动模式，无尾随或非法闯入特征。"

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
请从下面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",
  "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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "放学后长期只有浴室活动",
  "reasoning": [
    "推理步骤1: 放学后长时间只有浴室相关信号",
    "推理步骤2: 缺少回到儿童房或公共区域的链路",
    "推理步骤3: 存在异常风险"
  ],
  "key_evidence": [

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示为正常的家庭晚间降温过程及次卫灯光误报/定时开启，无安全威胁。",
  "reasoning": [
    "推理步骤 1: 温度数据分析。所有房间的温度传感器读数（如 kids_room_temp_sensor）均在 23°C - 24°C 之间波动，且数值随时间推移呈现缓慢下降趋势（从约 24.4°C 降至 23.3°C），这符合傍晚关闭空调或自然散热的正常物理规律。Matter 协议中温度通常以 0.1°C 为单位，因此读取值需除以 10，当前数值完全在舒适居住范围内，不存在过热或设备故障导致的漂移。",
    "推理步骤 2: 占用状态分析。虽然儿童房 (kids_room) 和客厅等区域在 15:00 至 17:40 期间持续报告无人 (Occupancy = 0)，但这与跨天摘要中显示的各房间活动量一致，且考虑到这是下午晚些时候，住户可能已离开该区域或处于休息状态，属于正常的生活作息模式，未检测到入侵迹象（因为门窗传感器未触发异常报警逻辑，且全屋无其他闯入特征）。",
    "推理步骤 3: 异常事件关联分析。日志中出现的 `second_bathroom_light` 在 16:30、16:45、17:00 多次变为 True，而该房间此时无人且非活动时间。然而，结合上下文，这可能是智能照明系统的定时任务、场景联动（如离家模式下的安防灯测试）或用户远程控制的误操作记录。由于没有伴随漏水、烟雾或其他危险信号，且温度正常，此行为被判定为非恶意或无害的自动化行为，不构成安全威胁。"
  ],
  "key_evidence": [
    "儿童房温度从 24.44°C 稳定下降至 23.39°C，符合环境散热规律，无异常高温。",
    "全屋运动传感器长时间为 0 但未触发入侵警报，且无门窗接触传感器异常开启记录。",
    "次卫灯光频繁开启但无相关危险事件（如漏水、烟雾）伴随，推测为自动化控制而非人为入侵。"
  ],
  "recommended_actions": [
    "无需紧急干预，系统运行正常。",
    "建议检查智能家居 App 中的次卫灯光设置，确认是否为预期的定时任务或场景联动，若非预期可调整配置。"
  ]
}

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
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": [
    "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。

```json

  "threat_description": "未检测到安全威胁，日志显示为正常的家庭日常活动模式。",
  "reasoning": [
    "1. 人员活动轨迹符合逻辑：06:38 次卫亮灯，随后 06:51 厨房亮灯（可能准备早餐或洗漱），07:37 厨房关灯，符合早晨起床后的常规活动。",
    "2. 儿童房活动正常：08:37 儿童房传感器检测到有人（Occupancy=1），且持续至下午，期间温度数据稳定（约24-25摄氏度），无剧烈波动，表明孩子在房间内休息或玩耍，无异常滞留或紧急情况。",
    "3. 门锁状态安全：16:14 入户门执行了手动上锁操作（LockState=2），且门磁传感器显示关闭（False），表明住户回家并正确反锁，无非法入侵迹象。",
    "4. 设备联动合理：16:10 儿童房开灯与16:14 进门时间接近，可能是孩子进入房间或家长检查房间；16:30 次卫再次开灯，结合之前的活动，属于正常的晚间前段活动。",
    "5. 无危险信号：厨房灶具、烟雾报警器、漏水传感器在日志时间段内无报警记录；空调和灯光控制均在正常范围内。"

    "推理步骤 3: 虽然该时段有人员活动（occupancy=1），但如此高的温度读数对于室内环境极不寻常，且数值呈现无规律的锯齿状波动，符合传感器校准失效、硬件故障或信号干扰导致的'漂移'特征，而非真实的温度升高。"
