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
以下是过去 3 天的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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",

    "关键证据2"
  ],
  "recommended_actions": [

}
```

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。

    " occupancy 模式验证：卧室 (bedroom) 在早晨有人员进入并持续存在，随后客厅 (living_room)、厨房 (kitchen) 和玄关 (entrance) 依次出现活动轨迹，且各房间运动传感器读数与跨天摘要中的高频计数一致，表明住户在家中正常移动，无长时间滞留或异常徘徊。",
    " 设备状态一致性：温度传感器数值（如 living_room_temp_sensor 的 2524-2558）换算后约为 22°C-25°C，处于舒适且安全的室温范围；门窗接触传感器和烟雾报警器未触发报警事件；门锁操作记录清晰，未见非法尝试或卡死现象。",
    " 排除误报：虽然部分时间段多个传感器同时报告 'Occupancy=1'，但这符合多人在同一空间或视线重叠的正常物理场景，结合历史数据看属于基准行为而非异常。"

## 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_description": "做饭时间异常短",
  "reasoning": [

    "时间线分析：所有事件均发生在白天（06:00 - 14:00），符合独居老人正常的起床、用餐和活动规律，未发现深夜异常活动或非授权时段的活动。",
    "行为一致性：厨房灶具 (kitchen_cook_surface) 的开启与关闭均有明确的 occupancy 传感器数据支持（有人在厨房时开启，有人离开后关闭），且持续时间合理（约 5-10 分钟），排除了无人看管烹饪的风险。",
    "环境状态稳定：客厅和卧室的温度传感器读数在 24°C-26°C 之间波动，处于舒适且安全的范围内；未检测到烟雾报警器触发或温度急剧升高的迹象。",
    "人员分布逻辑：运动传感器在各房间的状态变化连贯，例如从玄关进入后，客厅、厨房、卧室的占用状态随之更新，没有出现人员凭空消失或出现在不可能区域的逻辑矛盾。",
    "设备运行正常：窗帘开合、灯光开关等操作均伴随合理的上下文（如准备休息或调整光线），未见设备卡死或误报现象。"
  ],
  "key_evidence": [
    "厨房灶具操作严格遵循'人在操作'的逻辑，无长时间无人看管记录。",
    "全屋温度传感器读数稳定，无高温预警或烟雾报警信号。",
    "各房间 occupancy 传感器数据流转自然，符合单人活动的物理路径。"
  ],
  "recommended_actions": [
    "继续保持当前的设备监控频率，无需额外干预。",
    "建议定期（如每周）人工检查一次烟雾报警器和漏水传感器的电池及功能状态，作为预防性维护。"
  ]

System:
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
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

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": [

    "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": "none",
  "threat_description": "日志显示独居老人生活规律，设备状态与时间戳逻辑一致，未发现入侵、火灾或健康异常迹象。",
  "reasoning": [
    "1. 行为模式分析：住户在三天内的活动轨迹（起床、厨房活动、卧室休息、晚间活动）高度一致且符合独居老人的正常作息习惯，无长时间未活动的‘异常静默’或深夜异常出入。",
    "2. 环境数据合理性：温度传感器数值（如客厅 25°C-26°C，卧室 23°C-24°C）处于舒适且合理的范围，且随昼夜变化呈现正常的降温趋势，无高温预警或传感器漂移导致的乱码。",
    "3. 设备联动逻辑：厨房灶具关闭后灯光随之关闭/开启，运动传感器触发与人员移动时间吻合，所有 Actuator（执行器）和 Sensor（传感器）的状态变化均符合物理因果律，未发现设备卡死或误报。",
    "4. 安全设备状态：烟雾报警器、漏水传感器等关键安全设备在日志中未触发报警事件，且无相关异常状态报告，表明系统运行正常。"
  ],
  "key_evidence": [
    "连续三天同一时间段内，厨房灶具 (cook_surface) 均在有人活动时开启，并在无人时自动关闭，逻辑闭环完整。",
    "卧室温度传感器读数从白天的 24°C 左右逐渐下降至晚上的 22°C 左右，符合夜间自然散热规律，排除了传感器故障。",
    "入户门 (entrance) 和窗户 (contact_sensor) 传感器仅在白天特定时间点有短暂占用记录，其余时间均为空闲状态，无非法闯入迹象。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期（如每周）人工检查一次老人身体状况及家中水电燃气安全，作为常规关怀措施。"
  ]
}

System:
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
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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",

  ],
  "recommended_actions": [

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。

System:
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: ...",
    "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。

Rejected response:

  "threat_description": "检测到厨房区域存在严重的温度异常升高，且伴随无人值守状态，极可能引发火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间与环境分析。日志显示时间为凌晨 02:10 至 04:05，属于独居老人的夜间睡眠时段，此时住户通常不在活动区。",
    "推理步骤 2: 占用状态分析。在温度急剧上升期间（02:10 - 04:05），厨房运动传感器 (kitchen_occupancy) 多次报告为 0（无人），仅在 02:10、02:35、02:50 短暂出现 1 的读数，随后又迅速归零或保持极低频率，表明该区域处于无人看管状态。",
    "推理步骤 3: 温度趋势分析。厨房温度传感器读数从 02:10 的约 23.3°C (2336 mK) 持续单调上升至 04:05 的约 24.0°C (2402 mK)，增幅显著且无回落迹象。相比之下，卧室和客厅温度虽有波动但相对平稳。这种在无人状态下厨房温度的持续攀升是典型的电器过热或灶具未关特征。",
    "推理步骤 4: 设备行为关联。虽然厨房灯在 02:50 开启，但这可能是自动感应或误触，无法解释长达近两小时的持续高温。结合独居老人背景，若发生此类情况，老人可能因听力下降或睡眠中未能察觉危险，导致火势蔓延。"
