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",

    "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。

  "reasoning": [
    "推理步骤 1: 分析日志发现从 16:40 开始，living_room_temp_sensor 报告的 MeasuredValue 在 2300 到 2384 之间波动。考虑到 Matter 协议中温度通常以 0.1°C 为单位存储，这些数值实际代表 23.0°C - 23.8°C，这在逻辑上是合理的；然而，若系统未进行单位转换直接显示原始值，或者该设备固件将整数部分误报为摄氏度（即实际温度高达 2300°C），则构成严重异常。",
    "推理步骤 2: 进一步观察发现，在 19:00 左右，kitchen_temp_sensor 的读数突然跳变至 2424 和 2488。结合同一时间段 kitchen_cook_surface 被开启的事件，如果这是真实温度，意味着厨房瞬间达到 2400°C+，这会导致火灾并烧毁房屋，显然不符合常理。更可能的情况是传感器硬件故障、通信干扰导致的数据包解析错误，或者是固件 Bug 导致的数值溢出/错位。",
    "推理步骤 3: 对比卧室温度传感器（bedroom_temp_sensor）在同一时间段的读数（约 2100-2200），虽然也偏高，但趋势相对平稳且与客厅/厨房的剧烈跳变模式不同。这种多房间传感器同时出现非物理级高读数的现象，极大概率不是环境变化引起的，而是传感器本身的 malfunction（故障）或网络传输中的数据包损坏。特别是厨房传感器在烹饪开启后数值飙升，属于典型的传感器失效特征。",

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。

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。

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
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。

    "推理步骤2: 直接切到卧室活动",
    "推理步骤3: 偏离既往居家路径"

  ]
}

Rejected response:
```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示正常的家庭晚间活动模式，包括住户回家、开启灯光空调及门锁操作，未发现安全威胁。",
  "reasoning": [
    "时间线分析：日志始于凌晨（00:00）主卧无人，随后在早晨（07:22）入户门传感器检测到开门/关门动作，符合正常起床或外出归家逻辑。",
    "行为一致性：下午至傍晚期间，虽然客厅和次卧运动传感器多次报告为'0'（无人），但温度传感器持续上报数据且数值稳定（约 23°C），表明设备在线且环境正常，非死机或离线。",
    "关键事件验证：18:07 分发生了一系列连贯的‘回家’事件：入户门锁被手动上锁（LockOperation=1），紧接着入户门接触传感器变为 False（门开），随后客厅灯、空调开启，最后客厅运动传感器变为 1（有人）。这一序列完全符合住户下班回家并进入客厅的正常行为模式。",
    "无异常指标：未检测到烟雾报警、漏水、非法入侵（如门开后长时间无人）、设备状态突变或传感器数据漂移等异常特征。"
  ],
  "key_evidence": [

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": [

    "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。

    "推理步骤 2: 与此同时，厨房温度传感器读数在 18:00 后急剧攀升至 2600-2700+ (即 26-27°C)，并在 18:25 达到峰值 2699。虽然数值看似只是略高，但考虑到其他房间同时段无升温迹象，且该数值随时间持续非理性增长，不符合物理规律。",
    "推理步骤 3: 结合入户门开启和人员进入的日志，若真实发生火情或高温，通常会有烟雾报警器触发或人员迅速撤离反应，但日志中未见相关联动报警，且随后人员仍在屋内活动并开启空调，进一步佐证了温度读数不可信。",
    "推理步骤 4: 这种单一设备在特定时间段内出现远超环境常态且与其他关联设备（如相邻房间）数据完全背离的现象，是典型的传感器漂移或硬件故障特征，而非真实的热事件。"

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
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。

  "threat_description": "日志显示独居老人正常的晚间居家活动模式，无安全威胁或异常行为。",
  "reasoning": [
    "时间线分析：事件发生在 17:20 至 19:25 之间，符合独居老人的正常晚间作息（晚餐、休息准备）。",
    " occupancy 模式验证：客厅 (living_room)、卧室 (bedroom) 和厨房 (kitchen) 的运动传感器持续报告有人 (Occupancy=1)，且入户门玄关 (entrance) 也有间歇性活动记录，表明住户一直在室内正常移动，不存在长时间无人看管的情况。",
    "设备状态一致性：灯光开关操作 (OnOff.OnOff) 与运动检测同步，例如 19:00 开灯后不久检测到有人，19:05 关灯时可能处于短暂静止或离开特定区域，随后 19:10 再次开灯，这种频繁的明暗切换在老人起夜或整理物品时非常常见，属于正常行为而非故障。",
    "环境数据合理性：温度传感器读数（如客厅 23.4°C -> 22.8°C）随空调运行和时间推移呈现合理的下降趋势，数值在舒适范围内，未出现传感器漂移或故障导致的极端值；所有传感器数据相互印证，逻辑自洽。"
  ],
  "key_evidence": [
    "多房间 (Living Room, Bedroom, Kitchen) 运动传感器在长时段内持续报告 Occupancy=1，证明住户在场。",
    "灯光控制序列 (19:00 ON -> 19:05 OFF -> 19:10 ON) 与人体活动轨迹吻合，反映正常的室内走动行为。",
    "温度数据随时间自然变化，无突变或异常高/低值，排除设备故障。"
  ],
  "recommended_actions": [
    "无需采取紧急措施，系统运行正常。",
    "建议继续保持对独居老人居住环境的常规监控频率。"
