## 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",
  "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。

  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "连续多天不使用厨房",

  ]
}

```json
{

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "分析显示住户行为模式高度一致，设备状态与时间逻辑吻合，未发现安全威胁或异常。",
  "reasoning": [
    "1. 行为模式一致性：三天日志中，住户的起床、离家（门锁锁定）、返回及入睡时间高度稳定（例如均在 07:29-07:40 之间离家，08:35-09:00 之间离开客厅），符合正常生活规律，无入侵或尾随迹象。",
    "2. 温度数据合理性：所有温度传感器读数（如 2494 代表 24.94°C）均处于舒适且合理的室内环境温度范围内，且随空调运行和人员活动有正常的波动，未出现火灾风险的高温或传感器漂移/故障导致的异常数值。",
    "3.  occupancy 逻辑自洽：运动传感器的触发（Occupancy=1）与门锁开启、入户门接触传感器激活的时间点严格对应，且离开房间后传感器能正确复位为 0，表明传感器工作正常，无卡死或误报。"
  ],
  "key_evidence": [
    "三天内入户门锁锁定时间与开门时间间隔极短且规律，符合单人或固定家庭成员进出习惯。",
    "客厅与厨房温度在早晨升温过程中变化平缓，最高值未超过 26°C，排除了火情或设备过热风险。",
    "各房间 occupancy 状态变化与 door_lock/contact_sensor 事件存在明确的时间先后逻辑关系，验证了系统感知的一致性。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期校准温度传感器以确保长期精度，但当前无需紧急操作。"
  ]

## 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",

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: ...",

    "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": "behavioral_anomaly",
  "threat_description": "设备使用频率突然翻倍",
  "reasoning": [

    "推理步骤2: 频率显著高于普通居家行为",
    "推理步骤3: 更像异常强迫式操作"
  ],

    "环境监控正常：窗户接触传感器在 18:55 变为 False（打开），但结合上下文可能是为了通风或取物，且未伴随入侵警报或其他异常传感器联动；所有运动传感器读数与人员移动轨迹一致。",
    "无危险信号：全篇日志中未出现烟雾报警器触发、漏水检测、门锁故障（如反复尝试开锁）、传感器数据漂移或丢失等典型安全威胁特征。"
  ],
  "key_evidence": [
    "front_door_lock 解锁后立即跟随 living_room_occupancy 变为 1，表明是合法住户返回。",
    "kitchen_cook_surface 开启时间短（13 分钟）且随后关闭，无持续高温或烟雾报警记录。",
    "temperature_sensor 读数在整个时间段内保持稳定且处于舒适范围（22.8°C - 23.6°C），无异常波动。",
    "living_room_light_1 和 living_room_ac 的状态变化与 occupancy 检测到的时间点高度吻合，符合自动化或半自动化的日常使用习惯。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，当前系统运行正常。",
    "建议继续保持对厨房区域和门窗传感器的实时监控，特别是在夜间无人时。",
    "定期校准温度传感器以确保读数准确，防止因长期未校准导致的误报或漏报。"
  ]
}
```


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
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",

## 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": "behavioral_anomaly",
  "threat_description": "设备使用频率突然翻倍",
  "reasoning": [
    "推理步骤1: 同一设备短时间高频重复使用",
    "推理步骤2: 频率显著高于普通居家行为",
    "推理步骤3: 更像异常强迫式操作"
  ],
  "key_evidence": [
    "同一设备短时间高频重复使用",
    "频率显著高于普通居家行为",
    "更像异常强迫式操作"
  ],
  "recommended_actions": [
    "标记为异常设备交互模式，建议持续观察。"
  ]
}

{
  "is_anomaly": false,

  "threat_description": "日志显示正常的家庭晚间活动模式，无安全威胁或异常行为。",
  "reasoning": [
    "时间线分析：事件发生在傍晚至晚上（17:00 - 20:15），符合典型的下班回家、做饭、休息的家庭作息规律。",
    " occupancy 逻辑验证：客厅 (living_room) 在 17:30 短暂无人后，于 18:13 检测到有人进入，随后与厨房、餐厅、儿童房等多房间传感器同时报告有人状态，表明家庭成员正常在屋内移动和互动，不存在长时间无人却设备频繁动作的异常情况。",
    "设备联动合理性：用户在 18:40 开启灶具，18:56 关闭；19:47 启动洗碗机。这些操作均伴随相应的照明变化（如厨房灯开启）和温度波动，且后续有人员离开该区域（如 19:56 餐厅有人，但厨房未再报动作），符合正常烹饪流程。",
    "环境数据一致性：室内温度从 23.6°C 逐渐下降至 22.5°C 左右，空调系统（SystemMode=3，通常为制冷）在 17:43 启动，随后温度稳步下降，传感器读数稳定，无漂移或故障迹象。窗户接触传感器在 19:36 变为 False（打开），但在同一时间段内多个房间仍有人活动，且未触发入侵警报，结合上下文更可能是住户开窗通风而非非法入侵。",
    "无危险信号：烟雾报警器、漏水传感器等安全设备未在日志中报告异常状态，所有 actuator（执行器）动作均有明确的 user-initiated 前因（如手动开灯、开关电器）。"

    "温度传感器数据显示空调运行后室温自然下降，无突变或停滞。",
    "窗户传感器状态变化（False）发生时，其他区域仍有正常人员活动，未伴随门锁异常或紧急报警。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，当前系统运行正常。",
    "建议定期查看完整日志以确认窗户开启事件的持续时长，确保非长期未关窗导致的能源浪费或潜在风险。"
