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。

Chosen response:
{
  "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: 正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "key_evidence": [
    "正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "检测到厨房灶具在无人看管的情况下长时间运行，且伴随温度传感器数据异常（可能为故障或过热），存在极高的火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，厨房灶具 (kitchen_cook_surface) 在 10:50:30 被开启，随后在 11:28:00 关闭，持续了约 37 分钟。虽然期间有人员活动记录，但老人独居，长时间烹饪极易因分心导致忘关火。",
    "推理步骤 2: 更严重的是，在 12:05:00 灶具再次被开启，此时日志中没有任何后续的关闭事件（直到日志结束）。这意味着灶具处于‘未受控’的开启状态，属于典型的 Unattended Cooking（无人看管烹饪）场景。",
    "推理步骤 3: 关键证据在于 12:12:00 的温度读数。厨房温度传感器读数从正常的 25xx (约 25°C) 突然跳变为 2920 (即 29.2°C)。虽然数值本身看似合理，但在 Matter 协议上下文中，这种非线性的巨大跳变通常意味着传感器校准丢失、硬件故障或正在经历剧烈的热冲击（如起火初期）。结合灶具未关闭的状态，这构成了严重的火灾隐患。",
    "推理步骤 4: 考虑到住户是独居老人，其反应速度和应急处理能力相对较弱，系统必须将此类‘设备开启 + 温度异常/未关闭’的组合视为最高优先级的安全威胁。"
  ],
  "key_evidence": [
    "2026-08-17T12:05:00 kitchen_cook_surface | OnOff.OnOff = True (灶具开启)",
    "2026-08-17T12:12:00 kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2920 (温度传感器出现异常大数值跳变)",
    "日志截止时灶具仍处于开启状态，无关闭指令"
  ],
  "recommended_actions": [
    "立即远程通知住户或紧急联系人，告知厨房可能存在火情或设备故障。",
    "如果系统具备联动能力，尝试自动切断厨房电源或触发烟雾报警器。",
    "安排专人上门检查厨房状况，确认灶具是否已关闭及是否有烟熏痕迹。",
    "建议更换或校准厨房温度传感器，并检查灶具的安全联锁功能是否正常。"
  ]
}

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：

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",
  "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: ...",

    "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。

Chosen response:
{
  "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: 正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "key_evidence": [
    "正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"

Rejected response:

  "threat_description": "厨房温度传感器在灶具开启后出现严重数据漂移（从 25°C 跳变至 124°C），且随后数值异常回落，表明传感器可能故障或受到干扰，无法准确反映真实火险风险。",
  "reasoning": [
    "推理步骤 1: 在 2026-08-15T12:05:00，厨房灶具 (kitchen_cook_surface) 状态变为 True (开启)，此时厨房温度传感器读数约为 25°C (2532 mK)，符合正常室温范围。",
    "推理步骤 2: 在 2026-08-15T12:12:00，即灶具开启约 7 分钟后，厨房温度传感器读数突然飙升至 2920 mK (约 124°C)。考虑到灶具通常位于台面，距离天花板较远，且仅运行 7 分钟，室内空气温度不可能瞬间达到 124°C，该读数极不物理合理。",
    "推理步骤 3: 在 2026-08-15T12:15:00，读数又迅速回落到 2516 mK (约 24°C)。这种剧烈的“尖峰”现象（Spiking）是典型的传感器故障、信号干扰或校准错误特征，而非真实的火灾升温过程。若为真实高温，周围其他房间（如客厅、卧室）的温度也应同步显著上升，但日志显示其他区域温度稳定在 25°C 左右。",
    "推理步骤 4: 尽管烟雾报警器未触发，但依赖此故障传感器进行热预警将导致系统失效，存在潜在的安全盲区。"

  "recommended_actions": [
    "立即检查并更换厨房温度传感器，排除硬件故障或校准问题。",
    "在修复前，建议用户手动定期检查厨房是否有过热迹象，或暂时启用更灵敏的烟雾/一氧化碳探测器作为主要监控手段。",
    "审查 Matter 网络中该传感器的配置，确认是否存在数据包解析错误或通信干扰。"
