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:
{
  "is_anomaly": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "key_evidence": [
    "正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"

Rejected response:

{
  "is_anomaly": true,

  "threat_type": "fire_risk",
  "threat_description": "厨房灶具在无人看管的情况下长时间运行，且伴随温度传感器读数异常飙升，存在极高的火灾风险。",
  "reasoning": [
    "推理步骤 1: 识别设备状态变化。日志显示 kitchen_cook_surface (厨房灶具) 在 09:08、11:50、12:05 多次开启，但在 09:47 关闭后，于 11:50 再次开启。",
    "推理步骤 2: 分析 occupancy (占用) 与 actuator (执行器) 的时序关系。在 11:50 灶具开启时，living_room_occupancy 和 bedroom_occupancy 均为 1 (有人)，但随后在 12:09 至 12:35 期间，虽然客厅有人，但厨房区域并未检测到明确的持续占用信号（或用户可能离开厨房去其他房间）。更关键的是，从 11:50 到 12:35，灶具处于开启状态长达 45 分钟以上，而在此期间厨房温度急剧上升。",
    "推理步骤 3: 评估温度数据异常。厨房温度传感器 (kitchen_temp_sensor) 读数从正常的 ~25°C (25xx mK) 在 11:15 开始飙升至 2868 mK (~28.7°C)，并在 11:25-11:30 达到峰值 2946 mK (~29.5°C)。虽然 Matter 协议中温度通常以毫开尔文 (mK) 为单位，2946 mK 约为 26.3°C，看似正常，但结合上下文：11:50 灶具开启后，12:12 读数跳变至 2920，12:15 骤降至 2648，这种剧烈波动且伴随高温趋势（相对于卧室稳定的 24°C）表明传感器可能受到热源干扰或发生了漂移。然而，最危险的信号是**长时间烹饪行为**。即使温度读数因校准问题未达报警阈值，灶具在无明确“人在厨房”确认的情况下连续工作超过 40 分钟，属于典型的 unattended_cooking 场景，极易引发火灾。此外，11:51 出现 None 值暗示通信中断或传感器故障，增加了不确定性。综合来看，长时间开启灶具是主要风险点。",
    "修正推理步骤 3 (基于安全优先原则): 重新审视温度单位。若 2946 代表 29.46°C，对于有空调运行的家庭（客厅 25°C），厨房因烹饪升温至 29-30°C 是合理的物理现象，并非传感器故障。真正的异常在于**行为模式**：用户在 11:50 开启灶具，直到 12:35 日志结束前，灶具一直处于开启状态（OnOff=True），持续时间约 45 分钟。在此期间，虽然客厅有人，但没有证据表明有人一直在厨房操作。长时间无人看管的烹饪是智能家居中最常见的火灾隐患之一。",
    "最终结论：核心威胁是 unattended_cooking (无人看管烹饪)。尽管温度读数本身可能在合理范围内（取决于具体环境），但设备状态（灶具常开）与预期的安全行为（烹饪时间短、有人看管）不符，构成了显著的安全隐患。"
  ],
  "key_evidence": [
    "kitchen_cook_surface 在 11:50 开启后，直至日志结束 (12:35) 仍保持开启状态，持续时间超过 45 分钟。",

    "11:51 时刻 kitchen_temp_sensor 报告值为 None，表明传感器可能存在瞬时故障或通信丢失，增加了监控盲区。"

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
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": false,
  "confidence": "medium",
  "threat_type": "none",
  "threat_description": "当前日志更符合正常模式，不建议报警。",
  "reasoning": [
    "推理步骤1: 正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "key_evidence": [
    "正常样本只有厨房局部升温并伴随灶具开启；异常样本是多房间同步升温。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房灶具在无人看管的情况下开启，且伴随温度传感器读数异常飙升（疑似故障或极端过热），存在严重火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-07-19T12:05:00 时，厨房灶具 (kitchen_cook_surface) 状态变为 True (开启)。",
    "推理步骤 2: 此时及随后的一段时间内 (12:05 - 13:00)，所有房间的运动传感器 (occupancy_sensor) 均报告 Occupancy = 0，表明厨房区域无人，属于典型的‘无人看管烹饪’场景。",
    "推理步骤 3: 关键异常点在于 2026-07-19T12:12:00，厨房温度传感器读数从正常的 ~2500 (约 25°C) 瞬间跳变至 2920 (约 29.2°C 或更高，取决于单位换算逻辑，但相对于环境是剧烈波动)，随后又回落。这种剧烈的温度读数变化结合灶具开启和无人状态，极可能是传感器检测到局部高温（如起火前兆）导致的读数漂移，或者是传感器本身故障导致误报高温，无论哪种情况，都构成了极高的火灾隐患。",
    "推理步骤 4: 综合来看，无人状态下开启热源设备，且温度数据出现不可解释的剧烈波动，符合火灾风险的典型特征。"

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。

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。

## 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",

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. 排除真实威胁：虽然涉及烟雾报警器，但状态明确标记为 'TestInProgress'（测试进行中），而非 'FireDetected' 或 'SmokeDetected'。且两个区域的报警器几乎同时触发并结束，符合用户手动按下测试按钮或系统自动执行定期自检的特征，而非随机发生的火灾报警。",
    "3. 结合环境背景：在此期间（09:00-10:25），家中多个房间（卧室、厨房、玄关、客厅）的运动传感器持续报告有人活动（Occupancy=1），表明住户处于清醒和活动状态，排除了因突发事故导致无人知晓的情况。温度数据也在正常范围内波动，未出现异常升温。",

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。
