## 任务
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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。

    "推理步骤 1: 分析时间线，在 2026-08-22T17:30:00 至 18:00:00 期间，所有房间（包括客厅、餐厅、卧室等）的运动传感器均报告 Occupancy = 0，表明屋内无人活动，且此前温度读数稳定在 23°C 左右（约 2340 mK）。",
    "推理步骤 2: 在 18:02:00，客厅温度传感器突然从 2315 mK (23.15°C) 跳变至 2840 mK (28.40°C)，随后在 18:04:00 又降至 2810 mK。这种在短时间内（2 分钟内）发生超过 5°C 的剧烈波动，且发生在无人状态下，不符合自然热力学规律（室内温度不会因无人而瞬间飙升）。",
    "推理步骤 3: 对比厨房温度传感器，其在同一时间段内读数平稳（2317 mK -> 2312 mK），排除了全屋环境温度突变的可能性。因此，该异常极大概率是客厅温度传感器本身发生了硬件故障、校准漂移或被干扰，属于 sensor_malfunction。",
    "推理步骤 4: 虽然厨房在 18:06:00 也有一个孤立的 2960 mK 读数，但随即恢复正常，可能是瞬时干扰；但客厅的持续高位读数（直到日志结束前仍高于正常水平）更指向设备本身的持续性故障风险。"

    "温度变化幅度 (>5°C) 和速度在无人环境下不符合物理常识。"
  ],
  "recommended_actions": [

## 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。

  "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。

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。

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: ...",

    "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。

    "1. 关键告警触发：日志显示在 2026-07-13T03:16:00，厨房烟雾报警器 (kitchen_smoke_alarm) 的 SmokeState 变为 1（报警状态），同时客厅烟雾报警器 (living_room_smoke_alarm) 的 InterconnectSmokeAlarm 和 ExpressedState 也变为 1，表明火警已联动并确认。",
    "2. 环境数据异常关联：在烟雾报警前（03:15），各房间温度传感器读数均出现显著跃升。例如，客厅温度从 03:10 的 2365 升至 03:15 的 2380，厨房温度从 2359 升至 2381。这种短时间内多区域同步升温不符合正常夜间降温规律，符合火灾初期热量扩散特征。",
    "3. 排除误报可能性：虽然所有运动传感器在凌晨 02:30 至 04:00 期间均显示 Occupancy = 0（无人），排除了因人员活动导致烹饪疏忽或设备故障被忽视的情况。结合温度持续攀升的趋势和烟雾报警的同时性，判定为真实火灾风险而非传感器漂移或误触。"

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
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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",
  "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:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房烟雾报警器触发，且客厅烟雾报警器联动报警，表明家中可能存在火灾或烟雾泄漏风险。",
  "reasoning": [
    "1. 识别核心告警：日志显示在 03:16:00，kitchen_smoke_alarm 的 SmokeState 变为 1（通常代表检测到烟雾/火情），紧接着 living_room_smoke_alarm 的 InterconnectSmokeAlarm 变为 1，表示多设备互联报警已激活。",
    "2. 关联住户状态：根据 occupancy_sensor 数据，从凌晨 02:30 到 04:25，所有房间（包括厨房、客厅、卧室等）的运动传感器均显示 Occupancy = 0，表明独居老人此时处于睡眠状态，未察觉异常。",
    "3. 排除误报可能性：虽然温度传感器数值较高（如 2398 等），但这是 Matter 协议中常见的以 0.01°C 为单位的原始值（即 23.98°C），属于正常室温范围，并非高温导致的误报。因此，烟雾报警更可能是真实的烟雾检测。",
    "4. 风险评估：对于独居老人而言，夜间发生火灾且无人察觉是极高风险场景，必须立即视为紧急安全事件处理。"
