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",

    "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。

    "关键事件逻辑验证：洗碗机在 14:00 启动，15:00 显示倒计时 5400 秒（90 分钟），17:05 倒计时减少至 5200 秒，表明设备正在正常运行中；入户门锁在 16:00 被手动锁定，随后多次检测到玄关入口有人经过（entrance_occupancy=1），这是家庭成员正常进出的表现，而非入侵尝试。",
    " occupancy 模式：多个房间（儿童房、餐厅、客厅等）的占用传感器频繁报 1，且与温度变化和设备操作时间吻合，反映了正常的家庭内部活动分布，没有发现长时间无人但设备运行的异常情况。"
  ],
  "key_evidence": [

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：

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: ..."

    "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:

  "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，表明厨房区域可能存在火灾或严重烟雾风险。",
  "reasoning": [
    "1. 核心事件识别：日志显示在 2026-07-07T03:16:00，`kitchen_smoke_alarm` 的 `SmokeState` 变为 1（报警状态）。紧接着在 03:16:00 和 03:17:00，`living_room_smoke_alarm` 的 `InterconnectSmokeAlarm` 和 `ExpressedState` 也变为 1。这符合 Matter 协议中烟雾报警器互联（Interconnect）的标准行为，即一个探测器报警，其他联网探测器同步报警。",
    "2. 排除误报可能性：虽然凌晨 3 点通常是睡眠时段，但所有房间的运动传感器（occupancy_sensor）在该时间段均显示为 0（无人），说明住户正在睡觉，未对警报做出反应。然而，温度数据并未显示出极端的、瞬间的升温（例如从 23°C 瞬间升至 50°C+），而是呈现缓慢波动（厨房温度从 ~2330 缓慢上升至 ~2384 等，注意单位可能是 0.01度 Celsius，即 23.3°C - 23.8°C，属于正常室温范围）。这表明可能并非明火大火，而是烹饪残留烟雾、蒸汽积聚或设备故障导致的报警，或者是真实的早期火灾迹象（如电线过热产生的微量烟雾）。鉴于烟雾报警器的敏感性，必须视为真实威胁处理。",
    "3. 风险评估：独居老人在深夜睡眠中对烟雾警报不敏感，若发生真实火情，逃生时间窗口极短。即使是由烹饪残留物引起的假阳性，也反映了厨房环境存在潜在隐患（如油污堆积、通风不良或电器老化）。"

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。

    "3. 评估安全风险：烟雾报警器是关键的消防安全设备。如果其处于 'Contamination' 状态，意味着它可能无法正确检测真实的烟雾，或者会频繁产生误报导致用户关闭电源。特别是在 08-29 住户不在家的情况下，若发生火灾，该设备极大概率无法提供有效警报，构成严重的安全漏洞。"

## 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。

  "threat_type": "fire_risk",
  "threat_description": "厨房烟雾报警器触发，且室内温度呈现异常快速上升趋势，存在真实火灾或设备过热风险。",
  "reasoning": [
    "1. 关键告警触发：日志显示在 03:16:00，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，表明系统已检测到烟雾并联动报警。",
    "2. 伴随温度异常升高：在烟雾报警前后，厨房温度传感器读数从 02:55 的 2363 (23.63°C) 持续上升至 04:10 的 2412 (24.12°C)，且上升速率较快。虽然绝对温度未达极高值，但在深夜无人活动时段（所有 occupancy_sensor 均为 0），这种非环境自然变化的升温结合烟雾报警，高度指向局部热源失控（如电器短路、余烬复燃等）。",
    "3. 排除误报与正常行为：此时段（凌晨 3-4 点）所有房间运动传感器均显示无人在家（Occupancy=0），排除了住户烹饪产生油烟导致误报的可能性。独居老人模式下，深夜突发火情属于最高优先级安全威胁。"
