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。

    "传感器数据合理性：温度传感器读数（如 kids_room_temp_sensor 的 2241-2264 mK，即约 22.4-22.6°C）处于舒适且合理的室温范围，数值波动符合环境变化，未出现漂移或故障特征。所有设备状态变化（开关灯、关空调、锁门）均有人口在场作为前提，逻辑自洽。"
  ],
  "key_evidence": [
    "22:41:32 front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Manual) 表明住户主动锁门。",
    "厨房设备在无人长时间停留时自动关闭（如 06:59 关闭灶具），且烹饪时段与人员活动高度重合。",
    "全房屋温传感器读数稳定在 22°C 左右，无异常高温或低温报警。"
  ],
  "recommended_actions": [

    "建议继续保持当前的设备联动策略，确保离家时自动检查门窗和电器状态。"

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：

  "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: ...",
    "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": "child_safety",
  "threat_description": "家长睡后儿童使用厨房电器",
  "reasoning": [
    "推理步骤1: 深夜厨房灯和灶具被打开",
    "推理步骤2: 儿童房活动状态变化",
    "推理步骤3: 缺乏成人陪同上下文"
  ],
  "key_evidence": [
    "深夜厨房灯和灶具被打开",
    "儿童房活动状态变化",
    "缺乏成人陪同上下文"
  ],
  "recommended_actions": [
    "按儿童厨房危险行为处理，建议立即干预。"
  ]
}

{
  "is_anomaly": true,
  "confidence": "low",
  "threat_type": "intrusion",
  "threat_description": "存在异常，但原因更可能属于其他类别。",
  "reasoning": [
    "推理步骤1: 日志里有异常，但我把它归因为另一类威胁。"
  ],
  "key_evidence": [
    "深夜厨房灯和灶具被打开"
  ],
  "recommended_actions": [
    "建议按该错误类别处理。"
  ]
}


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

  "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。

    "推理步骤 3: 虽然此时室内多个房间（客厅、餐厅、儿童房等）检测到有人活动，且温度读数稳定，排除了火灾或入侵成功的迹象，但门锁本身的持续报错构成了明确的安全威胁信号，需要立即干预以防止物理入侵或设备彻底损坏。"

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。

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": "child_safety",
  "threat_description": "儿童反复尝试打开受限区域",
  "reasoning": [
    "推理步骤1: 同一门锁短时间连续操作失败",
    "推理步骤2: 来源为按键输入",
    "推理步骤3: 符合儿童尝试受限区域的风险模式"
  ],
  "key_evidence": [
    "同一门锁短时间连续操作失败",
    "来源为按键输入",
    "符合儿童尝试受限区域的风险模式"
  ],
  "recommended_actions": [
    "判为儿童高风险尝试开门，建议加强门锁与看护。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "lock_malfunction",
  "threat_description": "入户门锁在连续三次尝试使用键盘解锁时均失败，且随后门传感器状态异常，表明可能存在锁具故障或遭遇暴力破解/技术开锁尝试。",
  "reasoning": [
    "推理步骤 1: 日志显示在 2026-07-27T18:05:00 至 18:07:00 期间，front_door_lock 连续记录了三次 'LockOperationError(source=Keypad)' 事件。这表明用户（或入侵者）正在反复尝试通过键盘输入密码或代码来开门，但均未成功。",
    "推理步骤 2: 结合上下文，前几次操作（16:18, 17:50）均为成功的 Manual 手动操作，而此次连续失败极大概率不是正常的日常行为模式，更倾向于设备故障（如键盘模块损坏、电池接触不良）或外部攻击（如暴力试错密码）。",
    "推理步骤 3: 虽然日志中未直接显示 door_contact 变为 True（开门），但在 17:50:02 曾短暂记录为 False（可能表示门被打开过或传感器误报），紧接着就是连续的键盘错误。这种‘多次尝试失败’的模式是典型的 lock_malfunction 或 intrusion 前兆，鉴于没有检测到其他入侵迹象（如窗户开启、运动传感器在非正常区域触发），优先判定为锁具本身的功能性故障风险最高。"
  ],
  "key_evidence": [

  ],
  "recommended_actions": [
    "立即检查入户门锁的电池电量及键盘模块是否物理损坏，尝试更换电池或重置锁具。",
    "如果无法自行修复，建议联系专业锁匠上门检修，排除机械卡死或电子元件故障。",
    "暂时避免使用键盘解锁，改用机械钥匙开门，并监控后续是否有新的异常访问尝试。"

## 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。

{

  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "儿童活动从儿童房转移到阳台",
  "reasoning": [
    "推理步骤1: 儿童房活动后很快打开阳台门",
    "推理步骤2: 阳台灯被打开",

  ],
  "key_evidence": [
    "儿童房活动后很快打开阳台门",
    "阳台灯被打开",
    "缺少明确陪同信号"
  ],
  "recommended_actions": [
    "判定为儿童接近高处风险区域，建议立即干预。"
  ]
}

{

  "confidence": "high",
  "threat_type": "child_safety",
  "threat_description": "儿童活动从儿童房转移到阳台",
