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

  "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": "厨房烟雾报警器报告持续的污染状态（ContaminationState），表明传感器可能因灰尘、老化或故障产生误报风险，而非真实的火灾威胁。",
  "reasoning": [
    "1. 识别关键异常事件：日志中多次出现 `kitchen_smoke_alarm` 的 `SmokeCoAlarm.ContaminationState` 属性变化。具体为：2026-07-01 08:00 值为 1，2026-07-02 08:00 值为 2，2026-07-03 08:00 值为 3。",
    "2. 分析数值含义：在 Matter/Smart Home 标准中，ContaminationState 通常用于指示传感器探测腔内的污染程度（如灰尘积累）。数值从 1 增加到 3 表示污染程度随时间加剧，或者设备处于不同的报警/维护阶段。这通常是维护提醒或传感器脏污的信号，而非烟雾浓度（SmokeConcentration）或火警状态。",
    "3. 排除真实火灾风险：检查同一时间段内的其他传感器数据。厨房温度传感器（kitchen_temp_sensor）显示温度在 24°C - 25.5°C 之间波动，属于正常室温范围，没有出现火灾导致的急剧升温。同时，没有触发 `SmokeCoAlarm.FireAlarm` 或 `SmokeCoAlarm.SmokeAlarm` 等紧急报警属性。",
    "4. 结合行为模式：住户日常活动规律（早晨开灯、出门锁门、卫生间使用等）正常，无异常入侵或长时间未活动的迹象。因此，该异常更倾向于硬件维护问题（传感器需要清洁或更换），而非即时安全威胁。"

## 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",

    "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。

    "推理步骤 2: 关联洗碗机日志，OperationalState 显示为运行中 (1)，CountdownTime 从 5400 秒递减至 5200 秒，表明洗碗机正在按计划执行清洗程序，其产生的热量已被环境吸收并随时间消散，与温度下降曲线吻合，排除了‘未受监控烹饪’或‘设备卡死’的风险。",
    "推理步骤 3: 检查运动传感器日志，客厅、餐厅、儿童房、主卧及玄关等所有关键区域在 13:30 至 17:30 期间均报告 Occupancy = 0，结合时间窗口（下午 1 点至 5 点），这符合住户外出购物、工作或全家休息的正常行为模式，未发现入侵迹象或异常滞留。"

## 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

  "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。

    "2. 温度异常趋势佐证：在烟雾报警前（02:20 - 03:15），厨房温度传感器读数从 2335 (23.35°C) 持续上升至 2361 (23.61°C)，客厅温度也从 2319 (23.19°C) 上升至 2376 (23.76°C)。虽然绝对值看似不高，但在凌晨时段（通常环境温度较低或稳定），这种跨房间的同步、持续性升温是火灾早期热释放的典型特征。",
    "3. 排除误报可能性：所有房间的运动传感器（occupancy_sensor）在报警前后均保持为 0，说明屋内无人活动。独居老人在凌晨无人为操作导致误触的可能性极低，且没有烹饪行为（unattended_cooking 通常指人离开但灶具开启，此处更倾向于突发火情）。",

    "1. 识别异常模式：日志显示厨房烟雾报警器（kitchen_smoke_alarm）在7月5日08:00和7月6日08:00均触发了ContaminationState（污染/故障状态），7月7日08:00再次触发。这种连续三天在同一时间点（早晨8点）出现的相同非火警类报警是典型的设备故障或环境干扰信号。",
    "2. 排除真实威胁：在报警发生的时间段（07:30-08:30），虽然厨房运动传感器（kitchen_occupancy）有活动记录，但温度传感器读数仅从约25°C缓慢上升至25.5°C左右（例如7月5日从25.03升至25.53），这符合正常室温波动或人体散热，并未出现火灾导致的温度急剧飙升。同时，没有检测到CO警报或高温阈值突破。",
    "3. 结合住户画像分析：独居老人可能在早晨进行常规活动（如起床、洗漱、准备早餐）。如果这是正常的烹饪行为，通常不会导致烟雾报警器进入'ContaminationState'（通常指灰尘积累、传感器脏污或寿命到期），除非油烟极大且持续，但温度数据不支持高负荷烹饪。更可能的情况是传感器本身需要清洁或更换，或者存在持续的轻微干扰源（如加湿器雾气、灰尘）。由于是独居老人，依赖此类安全设备的可靠性至关重要，因此必须视为潜在的安全隐患进行处理。"

    "3. 结合上下文推理：该警报发生在早晨家庭成员活动高峰期（玄关、餐厅、儿童房均有 occupancy 活动），如果真是火情，应有其他联动反应或住户干预记录。连续三天的规律性“污染”报错，强烈暗示是传感器元件故障、灰尘积累导致的自检失败，或者是设备固件/硬件的周期性错误。"

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。
