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": "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": "入户门锁在连续多次按键尝试后发生操作错误，且随后出现异常的温度读数下降模式，表明可能存在锁具故障或遭受暴力破解/技术开锁尝试。",
  "reasoning": [
    "推理步骤 1: 日志显示在 2026-07-02T18:05:00 至 18:09:00 期间，front_door_lock 连续记录了 4 次 'LockOperationError(source=Keypad)' 事件。这表明有人正在反复尝试使用键盘解锁，但均告失败。",
    "推理步骤 2: 虽然此时屋内 occupancy 传感器（living_room, kids_room 等）显示有人存在，但连续的锁具报错通常意味着外部人员试图进入，或者内部人员在测试/重置锁具时遇到了硬件故障。考虑到时间点是傍晚，结合后续温度异常，需高度警惕外部入侵尝试或设备被恶意干扰。",
    "推理步骤 3: 更关键的异常在于温度数据。从 17:05 到 18:05，厨房和主卧温度正常（约 23.5°C），但在 18:05 之后，kids_room_temp_sensor 的读数开始呈现非自然的剧烈波动和持续下降趋势（从 2333 降至 2277），而客厅温度也同步下降。这种多房间温度传感器的协同‘漂移’或‘失灵’，极有可能是因为入侵者破坏了温控系统、切断了电源导致传感器掉线，或者是某种针对 Matter 设备的攻击导致了数据注入/篡改，亦或是物理入侵导致的空调/暖气关闭及门窗状态改变引发的连锁反应。",
    "推理步骤 4: 综合来看，单纯的误报概率较低。连续的门禁错误配合随后多个关键区域温度传感器的异常行为，构成了一个高置信度的安全威胁场景，首要怀疑对象是门锁故障或被攻击，其次是伴随的环境传感器数据完整性受损。"
  ],

    "2026-07-02T18:05:00 - 2026-07-02T18:09:00 期间 front_door_lock 连续 4 次报告 Keypad 操作错误。",
    "2026-07-02T18:05:00 之后，kids_room_temp_sensor 和 kitchen_temp_sensor 出现异常的数值跳变和持续下降趋势，与之前的稳定状态不符。"
  ],
  "recommended_actions": [
    "立即检查入户门锁的物理状态，确认是否被破坏、电池是否耗尽或机械结构卡死。",
    "联系智能家居服务商或专业维修人员检查门锁固件及通信模块，排查是否存在网络攻击或协议漏洞。",
    "检查儿童房及厨房区域的温度传感器是否因断电、物理损坏或人为干扰而失效，并校准或更换传感器。",
    "暂时加强该区域的物理安防措施（如安装临时监控），直到设备恢复正常。"

## 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: ..."
  ],

    "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": "high",
  "threat_type": "child_safety",
  "threat_description": "家长睡后儿童使用厨房电器",
  "reasoning": [
    "推理步骤1: 日志中出现了不存在的额外报警事件。"
  ],
  "key_evidence": [
    "我假设看到了一个未在日志中出现的 critical 告警。"
  ],
  "recommended_actions": [
    "按儿童厨房危险行为处理，建议立即干预。"
  ]
}


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",
  "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
{
  "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: 在此离家时段内，front_door_lock 设备在 18:05、18:06 和 18:07 连续记录了三次 'LockOperationError(source=Keypad)' 事件。这种短时间内的高频重复失败通常不是误操作，而是典型的暴力破解尝试或锁具本身的机械/电子故障。",
    "推理步骤 3: 结合上下文，虽然温度数据存在明显的漂移现象（如从 23.9°C 跳变到 23.4°C 后又回升），但这属于环境传感器校准问题（sensor_drift），不影响安全判断的核心逻辑。核心风险在于门锁在无人看管时反复报错，若为外部攻击则意味着极高的入室盗窃风险；若为内部故障，则可能导致住户无法回家或被困门外。"

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",
  "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: 尽管在 18:09:00 发生了一次成功的 LockOperation (Type=1, Manual) 并伴随 DoorLock.LockState 变为 2 (通常表示已锁定或正在执行锁定/解锁动作)，但在随后的 18:09:02，front_door_contact 传感器状态变为 False (门被打开)。",
    "推理步骤 3: 最关键的异常在于时间关联性：门打开的瞬间 (18:09:02)，living_room_light_1 和 living_room_ac 几乎同时被激活。虽然这可能是预设的‘回家模式’，但考虑到前几分钟刚发生过多次锁具错误尝试，这种自动化响应极有可能是入侵者利用系统漏洞触发的，或者是门锁本身存在严重故障（如误报解锁、机械卡滞导致无法保持锁定），而非正常的住户行为。"
