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",
  "reasoning": [

    "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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "检测到独居老人在夜间频繁起夜，活动模式规律且符合正常生理行为，未发现安全威胁。",
  "reasoning": [
    "1. 分析时间窗口：所有事件发生在 2026-07-01 的 22:45 至 23:28 之间，属于深夜时段。对于独居老人而言，夜间起床（起夜）是常见的生理需求。",
    "2. 分析活动路径与频率：日志显示卧室、厨房、客厅、玄关的运动传感器在约每 15-20 分钟内被触发一次（22:45, 22:50, 23:05, 23:08...），且卫生间 occupancy 传感器先变为 1（隐含在之前的逻辑中，虽然日志只记录了离开为0的时刻，但结合其他房间活跃，可推断有人活动）。这种高频次的短距离移动（卧室->卫生间/厨房->返回）符合老年人夜间如厕或喝水的习惯。",
    "3. 排除异常风险：没有检测到入户门锁开启、窗户打开、烟雾报警或漏水等危险信号。老人的活动轨迹局限在室内主要生活区域，未出现长时间静止（跌倒风险低）或剧烈无序运动。这种规律的夜间活动模式在独居老人家庭中属于正常行为。"
  ],
  "key_evidence": [
    "22:45 - 23:28 期间，卧室、厨房、客厅、玄关等多个区域传感器交替触发，表明有人在室内持续活动。",
    "卫生间 occupancy 传感器在 22:50 和 23:20 记录到 'Occupancy = 0'，暗示之前有人进入并离开，符合如厕后离开的特征。",
    "活动时间间隔规律（约15-20分钟一次循环），无门锁异常开启或火灾/泄漏警报。"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施。",
    "建议家属关注老人夜间睡眠质量及起夜频率，若频率过高可能涉及健康隐患（如前列腺问题或糖尿病），可考虑增加夜间地脚灯以预防跌倒。"
  ]
}
```

{
  "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": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"

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",

  ],
  "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。

    "3. 分析运动传感器模式：厨房、卧室、客厅、玄关的运动传感器在深夜频繁报告 Occupancy=1，这通常是因为 PIR 传感器的默认行为是周期性上报当前状态或存在微小移动（如呼吸、翻身、宠物走动），而非表示有人在进行剧烈活动。特别是卧室传感器持续在线，符合老人在床上休息的状态。",
    "4. 分析温度数据：各房间温度读数（约 21.5°C - 22.7°C）处于舒适且稳定的范围内，无急剧升温（火灾风险）或降温情况。温度数值以整数形式上报（如 2260 代表 22.60°C），符合 Matter 协议标准格式，无传感器漂移或故障迹象。",

  "recommended_actions": [
    "无需采取紧急措施。",

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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

{
  "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: 日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "key_evidence": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

{
  "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": [
    "日志中未出现持续矛盾、直接告警或高风险时序链路。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"

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
根据以下传感器与设备记录，评估目标设备当前工作状态是否正常。如异常，请给出故障判断依据。

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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "所有设备状态变化符合正常家庭晚间活动模式，未发现安全威胁或设备故障。",
  "reasoning": [
    "1. 温度数据合理性分析：日志中的温度传感器数值（如2319, 2245等）呈现典型的Matter协议整数格式（通常单位为0.01摄氏度）。换算后约为23.19°C至22.45°C，处于舒适的室内环境温度范围内，且随时间推移有正常的微小波动，无传感器漂移或故障迹象。",
    "2. 人员活动逻辑自洽：从17:55到22:41，多个房间的运动传感器（客厅、餐厅、主卧、儿童房、玄关）交替触发Occupancy=1，符合家庭成员在傍晚至睡前期间在不同房间活动的正常行为模式。次卧传感器显示Occupancy=0，表明该房间无人，符合预期。",
    "3. 关键安防事件正常：22:31客厅空调关闭，随后22:32入户门锁执行了手动锁定操作（LockOperationType=0），紧接着22:34玄关运动传感器再次触发。这一序列清晰地表明住户回家/进入家门并锁门的过程，属于正常的入室行为，非入侵。",
    "4. 无异常环境指标：厨房烟雾报警器、漏水传感器在此期间未触发任何报警事件，排除了火灾和水患风险。"
  ],
  "key_evidence": [
    "Temperature values (e.g., 2319 -> 23.19°C) are within normal indoor comfort range.",
    "Multiple occupancy sensors trigger sequentially across different rooms (Living Room, Dining Room, Master Bedroom), indicating normal family movement.",
    "Door lock manual lock event at 22:32 followed by entrance occupancy detection at 22:34 confirms legitimate entry and securing of the home."
  ],
  "recommended_actions": [
    "无需采取任何行动，系统运行正常。",
    "建议继续保持当前的自动化规则，确保夜间离家或就寝时的安防联动功能有效。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
