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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的夜间居家活动及设备状态更新。",
  "reasoning": [
    "1. **人员活动模式正常**：日志显示客厅（living_room）在22:15至23:55期间持续有人（Occupancy=1），而卧室（master_bedroom, second_bedroom）和玄关（entrance）在深夜时段（22:30-23:30）显示无人（Occupancy=0）。这符合典型的夜间休息模式，即主要活动区域集中在客厅，卧室处于睡眠或无人状态。",
    "2. **门锁操作合规**：在23:10左右，入户门传感器显示开启（StateValue=True），随即门锁执行了手动上锁操作（LockOperationType=0, LockState=1）。这一序列表明住户可能刚回家并锁门，或者检查了门锁状态后确认已锁好。没有发现非法入侵迹象（如未授权开锁或长时间门开未关）。",
    "3. **环境数据稳定**：所有温度传感器的读数在22.4°C至22.8°C之间波动，变化幅度极小且符合室内恒温环境的特征，无异常跳变或传感器故障迹象。",
    "4. **无危险设备触发**：厨房的烟雾报警器、漏水传感器以及灶具均无报警或异常激活记录。卫生间运动传感器间歇性归零（0）是正常的离开检测，未发现跌倒或长时间静止等健康风险信号。"
  ],
  "key_evidence": [
    "23:10:16 front_door_contact | BooleanState.StateValue = True (门被打开)",
    "23:10:17 front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Manual) (随后手动上锁)",
    "22:15-23:55 living_room_occupancy | OccupancySensing.Occupancy = 1 (客厅持续有人)",
    "22:30-23:30 master/second_bedroom_occupancy | OccupancySensing.Occupancy = 0 (卧室无人)"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议保持常规监控，确保夜间门锁状态与用户预期一致。"
  ]
}
```

{
  "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。

{
  "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
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",

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. 设备状态一致性：所有涉及的人员存在传感器均报告了合理的占用状态变化，没有发现长时间静止不动（可能跌倒）或完全无活动的情况。卫生间传感器的周期性清零表明有人进出使用，而非传感器故障。",
    "3. 环境参数正常：各房间温度读数在合理范围内（卧室约21.4-21.6°C，客厅/厨房约22.4-22.7°C），且随时间波动极小，未出现火灾或设备过热导致的温度骤升。未发现烟雾报警器或一氧化碳报警器的触发记录。",

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
监控系统标记了潜在异常。请分析下面的日志，判断是否需要采取响应措施，并给出建议。

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": "未检测到安全威胁，日志显示为正常的夜间家庭活动模式。",
  "reasoning": [
    "1. 分析时间窗口：所有事件发生在2026-08-18的22:25至23:30之间，属于典型的夜间就寝前或休息时段。",
    "2. 分析人员动线：主卧（master_bedroom）在22:25、22:45、23:05、23:25多次触发占用信号，表明住户主要在卧室休息。同时，玄关（entrance）、客厅（living_room）和卫生间/次卧区域有间歇性的占用信号（如22:26、22:46、23:06），这符合住户在睡前进行洗漱、喝水或短暂活动的正常行为逻辑。",
    "3. 排除异常特征：没有发现门锁被非法开启、窗户异常打开、烟雾报警或漏水传感器触发等危险信号。占用传感器的频繁切换（On/Off）是PIR传感器检测到人移动后的正常反馈，且各房间活动存在时间差，符合同一人在家中不同位置移动的规律，而非入侵者快速穿越多个房间的特征。"
  ],
  "key_evidence": [
    "主卧占用传感器在22:25-23:25期间持续或间歇性激活，表明住户在卧室休息。",
    "玄关和客厅在22:26、22:46、23:06出现短暂的占用信号，与主卧活动时间间隔合理，符合睡前常规活动。",
    "无任何安防类设备（门锁、窗户、烟雾、漏水）的告警或异常状态记录。"
  ],
  "recommended_actions": [
    "无需采取任何紧急措施。",
    "建议继续监控，若后续出现非居住时间的异常闯入或长时间无活动但传感器仍活跃的情况，再行评估。"
  ]
}
```

{
  "is_anomaly": true,

  "reasoning": [
