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
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",

## 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。

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. 分析趋势模式：在一小时内，CO浓度从35ppm线性上升至59ppm，增幅显著且方向单一，表明存在持续的泄漏源或燃烧不充分的情况，而非偶发的瞬时干扰。",
    "3. 结合环境背景：虽然洗碗机在19:32开启，但通常不产生大量CO；若厨房使用燃气灶具（cook_surface），此趋势极可能源于燃气泄漏或通风不良导致的燃烧废气积聚。尽管当前数值低于典型的立即致命阈值（如100-200ppm以上），但59ppm已接近OSHA允许的8小时暴露限值（50ppm），长期暴露有害健康，且呈上升趋势预示风险加剧。",
    "4. 排除误报：温度传感器读数正常波动，无火灾高温迹象；其他房间活动正常，无入侵迹象，因此该异常主要指向厨房内部的环境安全问题。"

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": true,
  "confidence": "high",
  "threat_type": "carbon_monoxide",
  "threat_description": "厨房一氧化碳浓度呈现持续上升趋势，存在潜在的一氧化碳泄漏或燃烧不充分风险。",
  "reasoning": [
    "1. 识别关键异常数据：日志中记录了厨房烟雾报警器（kitchen_smoke_alarm）在三个时间点报告了一氧化碳浓度值：21:00时为35 ppm，21:20时为48 ppm，21:40时为59 ppm。",
    "2. 分析趋势特征：CO浓度在40分钟内从35 ppm线性上升至59 ppm，增幅显著且方向一致。根据Matter标准及一般安全阈值，室内CO浓度通常应接近0 ppm，超过35 ppm即需引起注意，超过50-60 ppm属于危险水平，可能引发头痛、恶心等症状，长期暴露有中毒风险。",
    "3. 排除误报与关联分析：虽然温度传感器数据显示厨房温度在22.4°C-22.9°C之间波动，处于正常室温范围，未出现火灾导致的高温飙升，但这并不排除燃气泄漏或燃烧不充分产生CO的情况。同时，客厅和卧室的 occupancy 传感器显示有人活动，说明住户在场，若发生急性中毒会有反应，但目前的缓慢上升更倾向于慢性泄漏或设备故障前的预警阶段。",
    "4. 综合判断：这种持续上升的CO读数不是正常的背景噪声，而是明确的安全威胁信号，必须立即干预以确认是否存在燃气泄漏或通风不良导致的CO积聚。"
