## 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: ..."
  ],

    "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:

{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁或异常模式，日志显示为正常的家庭晚间活动序列。",
  "reasoning": [
    "1. **入户行为分析**：17:45左右，前门门锁执行了手动上锁操作（LockState=2），随后前门接触传感器显示关闭（False）。紧接着在17:45:07，客厅 occupancy 传感器检测到有人（Value=1），且客厅主灯和空调开启。这符合住户下班回家、进门后开灯并调节室温的正常生活逻辑。",
    "2. **烹饪活动分析**：18:13厨房灯亮起，18:13:30灶具开启。这是典型的晚餐准备场景。虽然日志中未直接显示烟雾报警器触发或漏水传感器报警，但时间窗口较短（仅记录到18:30），且无其他危险信号，属于正常烹饪行为。",
    "3. **人员分布与设备联动**：从17:32开始，多个房间（儿童房、餐厅、玄关、主卧）的 occupancy 传感器陆续变为1，表明家庭成员分散在家中不同区域活动。18:00后次卧 occupancy 为0，符合无人居住状态。各房间温度传感器读数在23-24摄氏度之间波动，数值合理（Matter协议中通常为十分之一摄氏度，即23.0-24.0°C），无传感器故障迹象。",
    "4. **排除误报**：前门接触传感器在16:22曾短暂变为False（可能为误触或测试，或之前未完全闭合），但在17:45的离家/归家序列中表现正常。厨房温度传感器在18:14出现None值，可能是数据上报延迟或瞬时丢失，不影响整体安全判断，且后续有恢复趋势或未被标记为持续故障。"

    "17:45:13 living_room_light_1 | OnOff.OnOff = True - 灯光随人员活动开启",
    "18:13:30 kitchen_cook_surface | OnOff.OnOff = True - 正常烹饪行为",
    "各房间温度读数稳定在2300-2400范围内，无极端值"

## 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": [

    "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。

  "reasoning": [
    "1. 活动模式分析：日志显示从 17:20 开始，客厅（living_room）持续有人活动（Occupancy=1），直至深夜 23:00。这符合典型的居家晚间休闲、看电视或阅读的习惯。卧室（bedroom）在 18:11 至 22:16 期间也有间歇性活动记录，表明可能有第二人在卧室活动或主人频繁进出卧室，属于正常家庭互动。",
    "2. 厨房安全验证：18:53 灶具关闭，随后洗碗机启动（18:54），这是典型的晚餐后清洁流程。虽然中间有一次厨房温度传感器读数丢失（18:54:00），但随后立即恢复正常读数，且无烟雾报警触发，排除火灾风险。",
    "3. 传感器数据合理性：温度读数（如 2313 代表 23.13°C）随时间缓慢下降，符合夜间环境温度自然降低或空调调节后的趋势，无剧烈跳变或漂移现象。卫生间运动传感器在 19:24 和 21:24 显示无人（0），符合短暂使用后的离开行为。",
    "4. 照明与能耗逻辑：客厅灯在 09:50 开启（早晨），19:00 再次开启（傍晚/夜间），21:30 关闭（准备休息）。这种开关灯时间与 occupancy 传感器的人体存在情况高度吻合，没有发现长时间无人却开灯，或有人却不开灯的异常情况。"

  "key_evidence": [
    "客厅 Occupancy 传感器在 17:20-23:00 期间持续为 1，确认住户在家。",
    "厨房 Cook Surface 在 18:53 关闭，随后 Dishwasher 启动，符合正常餐后清理逻辑。",
    "Living Room Light 的开关时间与人员活动及时间段（早/晚）匹配，无异常长亮。",
    "各房间温度传感器读数平稳，无突变或故障迹象。"

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2"
  ],
  "recommended_actions": [

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. 设备状态检查：重点关注的厨房灯（kitchen_light）仅在特定时间点开关（如7月21日07:14关闭，7月22日06:31开启，7月23日18:40开启），且伴随其他房间的活动或温度变化，未发现长时间无人却持续亮灯或异常闪烁的情况。入户门锁在7月23日17:58有手动开锁记录，随后玄关/客厅灯光亮起，表明是住户回家，非非法入侵。",
    "3. 环境参数合理性：温度传感器读数（如2487, 2504等）在Matter协议中通常表示摄氏度乘以100的值（即24.87°C, 25.04°C），数值随时间缓慢波动，符合室内环境温度变化趋势，无突变或传感器卡死迹象。",

## 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。

Chosen response:
{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本只是晚间一次开关灯；异常样本短时间内重复高频操作。"
  ],
  "key_evidence": [
    "正常样本只是晚间一次开关灯；异常样本短时间内重复高频操作。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"
  ],
  "key_evidence": [
    "正常样本只是晚间一次开关灯；异常样本短时间内重复高频操作。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
}


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",
  "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": "未检测到安全威胁，日志显示为正常的家庭晚间活动模式。",
  "reasoning": [
    "1. **入户行为分析**：17:58 门锁手动上锁（LockState=2），随后玄关、餐厅、儿童房等区域运动传感器陆续触发，表明住户回家并分散至各房间，符合正常归家逻辑。",
    "2. **烹饪活动分析**：18:23 厨房灯开启，紧接着 18:23:30 灶具开启，这是典型的晚餐准备流程。虽然日志中未显示灶具关闭事件，但时间窗口较短（仅记录到18:25），且无烟雾报警器触发或温度异常飙升，属于正常烹饪初期状态，尚未构成“无人看管”风险。",
    "3. **环境数据合理性**：温度传感器读数（如 23xx）在 Matter 协议中通常代表 0.01°C 单位，即约 23.6°C 左右，处于舒适室温范围，无设备故障迹象。",
    "4. **无入侵迹象**：所有门窗传感器在住户回家后保持关闭状态（False），且无非法开锁尝试或暴力破坏记录。"

    "[18:24:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = None - 传感器短暂离线或无读数，但在后续及整体环境中未见持续故障，可能是瞬时通信问题，不影响整体安全判断"
  ],
  "recommended_actions": [
    "无需立即干预，建议继续监控厨房区域直至灶具关闭。",
    "若灶具长时间开启（超过30分钟）且无人员活动，系统应自动检查是否触发未看管烹饪警报。"
