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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "threat_description": "电器运行时间异常长",
  "reasoning": [
    "推理步骤1: 设备持续运行超过常规时长",
    "推理步骤2: 倒计时未按预期减少",
    "推理步骤3: 存在过热或故障风险"
  ],
  "key_evidence": [
    "设备持续运行超过常规时长",
    "倒计时未按预期减少",
    "存在过热或故障风险"
  ],
  "recommended_actions": [
    "标记为设备异常长运行，建议停机检查。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示厨房洗碗机正在正常运行，室内温度变化符合自然规律，无入侵、火灾或设备故障迹象。",
  "reasoning": [
    "1. 设备状态分析：厨房洗碗机 (kitchen_dishwasher) 在 14:00 启动 (OperationalState=1)，并在后续时间点报告倒计时 (CountdownTime)，表明其处于正常的运行周期中，未出现卡死或异常停止。",
    "2. 环境数据合理性：厨房温度传感器读数约为 25°C (2523 mK)，卧室和客厅温度随时间缓慢下降（从约 24°C 降至 23°C），这符合傍晚时分无人居住且空调关闭后的自然散热趋势，数值波动在正常范围内，无传感器漂移或故障特征。",
    "3.  occupancy 模式匹配：所有房间的运动传感器 (occupancy_sensor) 均持续报告为 0 (无人)，这与跨天摘要中提到的低活动量一致，且与洗碗机自动运行的场景相符（用户可能已离开厨房去其他区域或外出）。",
    "4. 安全设备状态：日志中未出现烟雾报警器、漏水传感器或门锁的报警事件或状态变更，关键安全设备似乎工作正常。"
  ],
  "key_evidence": [
    "kitchen_dishwasher | OperationalState.CountdownTime = 5400 (表明洗碗机正在按计划运行)",
    "living_room_occupancy / bedroom_occupancy / bathroom_occupancy 持续报告 Occupancy = 0 (与环境背景一致)",
    "kitchen_temp_sensor 读数稳定在 24-25°C 区间，无急剧升高或异常跳变"
  ],
  "recommended_actions": [
    "无需立即干预，系统运行正常。",
    "建议继续监控洗碗机完成后的状态，确保其能正常结束循环并复位。"
  ]
}
```


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
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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。

  "threat_description": "设备运行状态正常，温度下降符合洗碗机工作逻辑，无安全威胁。",
  "reasoning": [
    "推理步骤 1: 分析厨房温度传感器数据，发现从 12:50 到 17:25，温度值（单位应为 0.01°C）呈现持续且稳定的下降趋势（从 250.2°C 降至 234.8°C），这符合洗碗机在清洗和烘干过程中消耗热量或环境自然降温的物理规律，不存在异常升温导致的火灾风险。",
    "推理步骤 2: 检查洗碗机状态日志，OperationalState 显示为运行中（1），CountdownTime 从 5400 秒逐渐减少至 5200 秒，表明设备正在按计划执行任务，未出现卡死、意外停止或超时等故障迹象。",
    "推理步骤 3: 结合 occupancy_sensor 数据，虽然客厅、卧室、卫生间无人，但厨房作为作业区域有设备运行，且温度变化与设备运行时间高度相关，属于典型的居家生活场景，未发现入侵、尾随或传感器故障等异常模式。"
  ],
  "key_evidence": [
    "kitchen_temp_sensor 数据显示温度随时间单调递减，无突变或异常升高。",
    "kitchen_dishwasher CountdownTime 数值稳定递减，证明设备正常运行。"

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。

请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

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",

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。

  "threat_description": "厨房灶具在开启后长时间无人看管，且伴随温度传感器读数异常飙升，存在极高的火灾风险。",
  "reasoning": [
    "1. 识别烹饪行为：日志显示在 19:00:00 厨房灶具 (kitchen_cook_surface) 被手动开启 (OnOff=True)，随后在 19:20:00 关闭，间隔约20分钟。这通常对应一次正常的烹饪过程。",
    "2. 发现异常模式：尽管灶具已在 19:20:00 关闭，但厨房温度传感器 (kitchen_temp_sensor) 的读数并未如预期般下降或保持稳定，反而在 19:25:00 出现剧烈跳变至 3050 (约30.5°C)，并在 19:35:00 进一步飙升至 3220 (约32.2°C)。",
    "3. 排除正常干扰：虽然客厅和玄关有人员活动迹象，但厨房区域在 19:20 之后没有检测到新的 occupancy 信号（即无人进入厨房）。这种“热源已切断但环境温度持续快速上升”的现象，强烈暗示灶具并未真正完全关闭（例如处于小火慢炖、干烧状态）或者发生了燃气泄漏/电气故障导致余热积聚。",
    "4. 风险评估：Matter 协议中 TemperatureMeasurement 通常以厘度 (centi-degree Celsius) 为单位，3220 代表 32.2°C。对于密闭厨房而言，短时间内从 ~23°C 升至 32°C 且无人员活动，属于典型的未看管烹饪导致的过热或潜在火情前兆。"
