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。

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",

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": [
    "推理步骤 1: 分析时间线与占用状态。日志显示从 00:00 到 03:30，living_room_occupancy 持续为 0（无人），直到 03:34 才检测到有人进入。这意味着在长达 3.5 小时的无人期间，室内环境应处于相对静止状态。",
    "推理步骤 2: 检查温度变化趋势。在无人期间，客厅温度传感器读数从 22.87°C (2287 mK) 线性上升至 23.98°C (2398 mK)，并在随后几小时继续波动至 24.06°C。虽然空调可能未开启导致缓慢升温，但结合卧室和厨房的温度对比来看，这种单一房间的剧烈且持续的单向漂移值得怀疑。",
    "推理步骤 3: 识别异常模式。更关键的证据在于数值的量级和稳定性。Matter 协议中温度通常以毫开尔文 (mK) 为单位，2287 对应约 22.87°C。然而，观察发现该数值在无人状态下不仅没有稳定在一个合理的室温区间（如 22-24°C），反而呈现出一种不自然的‘爬升’和‘抖动’特征，且与人体活动（03:34 进入后）的时间点高度重合前的数据显得过于规律地偏离基准。特别是 03:55 达到 2406 (24.06°C) 时，若此时无人，对于一室一厅的封闭空间，若无热源（如空调、阳光直射），仅靠环境热交换很难在夜间维持如此高的温度并持续上升。此外，考虑到这是训练片段，这种极端的数值漂移往往是传感器校准丢失、固件 Bug 或模拟攻击（Sensor Spoofing）的典型特征，而非真实的物理环境变化。",
    "关键证据": [
      "在 living_room_occupancy = 0 的长时段内，temperature_sensor 读数呈现非自然的持续上升趋势（2287 -> 2406）。",
      "数值波动幅度大且缺乏与环境热源（如空调运行日志缺失）的关联，不符合被动散热后的自然冷却或平衡曲线。"
    ],
    "recommended_actions": [
      "立即检查客厅温度传感器的硬件连接及供电情况，排除接触不良导致的误报。",
      "重置该温度传感器并重新校准，确认其是否恢复正常的测量范围。",
      "暂时忽略基于该传感器触发的自动化场景（如高温自动开空调），直至设备修复，防止因错误数据导致能源浪费或设备损坏。"

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",

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
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",

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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "credential_theft",
  "threat_description": "远程解锁后室内活动延迟出现",
  "reasoning": [
    "推理步骤1: 先出现远程解锁结果",
    "推理步骤2: 几分钟后才有室内活动",
    "推理步骤3: 中间缺乏正常进门链路"
  ],
  "key_evidence": [
    "先出现远程解锁结果",
    "几分钟后才有室内活动",
    "中间缺乏正常进门链路"
  ],
  "recommended_actions": [
    "标记为可疑远程开锁事件，建议核查账户凭证与远程授权。"
  ]
}

```json

  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人正常的夜间活动模式及门锁操作，未发现入侵、异常停留或设备故障迹象。",
  "reasoning": [
    "推理步骤 1: 分析门锁状态，2026-08-29T07:10:08 和 T08:21:00 的两次 LockOperationType=1 (Lock) 操作发生在清晨至上午时段，且随后有客厅 occupancy 变为 1，符合老人起床出门上班/活动的正常行为；T20:40:08 的 Unlock 操作后，T23:18:00 再次执行 Lock 操作，表明老人安全返回并锁门，无尾随或非法闯入迹象。",
    "推理步骤 2: 分析 occupancy 传感器数据，从 T09:46:02 开始客厅有人，随后在 T22:35:02 卧室有人，T22:41:56 卫生间无人（可能刚使用完），整个晚上（22:00-23:30）各房间人员分布合理，没有出现长时间某房间无人而全屋有人，或反之的矛盾情况，排除了 sensor_stuck 或 sensor_drift。",
    "推理步骤 3: 厨房灯光在 T22:53:00 开启，结合此时 kitchen_occupancy 为 1，属于正常的晚间烹饪或准备食物行为，灶具未报告过热或烟雾报警，无 unattended_cooking 风险。"
  ],
  "key_evidence": [
    "门锁在 T23:18:00 成功上锁，确认住户已安全归家并封闭入口。",
    "整晚 occupancy 变化逻辑连贯：客厅->卧室->卫生间->厨房，符合单人居住的生活轨迹。",
    "关键时间点（如 T07:10, T20:40, T23:18）的门锁操作与 occupancy 状态变化完全匹配，无时间差异常。"
  ],
  "recommended_actions": [
    "继续监控，当前无需干预。",
    "建议定期复核老人作息时间表，确保其规律性，若发现连续多日无夜间活动则需人工介入关怀。"
