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。

    "2.  occupancy（占用）状态分析：日志中频繁出现的 Occupancy = 1 是运动传感器的周期性心跳或状态上报，而非连续的人体移动轨迹。由于这是“已选日志”片段，且时间间隔固定（每5分钟一次温度，每20分钟左右一次占用上报），这种规律性的状态保持符合独居老人在家休息时的正常行为模式。",
    "3. 卫生间活动分析：卫生间运动传感器在 22:18、22:48、23:18 出现 Occupancy = 0，这通常表示人员离开卫生间。结合其他区域（客厅、卧室、玄关）持续有占用信号，说明老人并未长时间被困在卫生间，排除了跌倒后无法求助的风险。",

## 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": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到疑似非法入侵：入户门在无人看管状态下被打开，且厨房窗户随后也被打开，伴随室内温度持续下降。",
  "reasoning": [
    "推理步骤 1: 在 18:16:02，front_door_contact (入户门传感器) 状态变为 False (打开)。此时 entrance_occupancy (玄关运动传感器) 尚未报告有人进入 (直到 18:26:03 才报告 Occupancy=1)，且 master_bedroom_occupancy (主卧) 在 18:17:00 已显示有人，表明住户可能正在卧室休息或活动，未直接守在门口。",
    "推理步骤 2: 在 19:03:30，kitchen_window_contact (厨房窗户传感器) 状态变为 False (打开)。此时 living_room_occupancy 和 entrance_occupancy 均显示为 1，但考虑到之前入户门开启的时间点，结合后续行为分析，这极可能是入侵者为了通风或逃离而进行的动作，或者是利用开门机会潜入后操作。",
    "推理步骤 3: 从 18:16 到日志结束，室内温度（客厅、厨房）呈现持续且显著的下降趋势（从约 23.2°C 降至 22.4°C），这与夜间空调关闭或开窗散热后的自然冷却曲线不完全一致，尤其是在门窗频繁开合的情况下，进一步佐证了非正常的通风/入侵行为导致的热量流失。",
    "推理步骤 4: 虽然 entrance_occupancy 多次报告为 1，但这可能是误报（如宠物移动、光影干扰）或是入侵者在屋内移动。关键在于“入户门先开后窗再开”的序列，以及温度异常下降，构成了完整的入侵证据链。"

    "18:16:02 front_door_contact 变为 False (门开)，随后长时间未立即关闭。",
    "19:03:30 kitchen_window_contact 变为 False (窗开)。",
    "全时段室内温度持续显著下降 (23.2°C -> 22.4°C)，与正常居住模式下的恒温控制不符。"
  ],
  "recommended_actions": [
    "立即通知住户家中可能存在入侵者，建议其保持警惕或联系警方。",
    "检查入户门锁和厨房窗户的物理锁具是否完好，确认是否有被破坏痕迹。",
    "调取相关时间段的安全摄像头录像进行复核。",
    "暂时将智能门锁设置为最高安全等级，并启用实时入侵警报推送。"
