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。

    "2. **人员活动模式**：入口玄关运动传感器（entrance_occupancy）在 13:00-14:40 期间多次触发（Occupancy=1），表明有人在家门口附近活动或进出，但客厅、卧室等核心休息区域的所有运动传感器均保持为 0（无人）。这种“门口有人但内部无人”的模式通常对应于住户在家门口整理物品、短暂停留或访客来访，并未发现强行闯入或长时间滞留室内的异常行为。",
    "3. **环境数据一致性**：所有房间的温度传感器读数在 24°C - 25°C 之间波动，变化平缓且符合夏季室内空调或自然通风下的正常热力学规律，未发现因火灾、设备故障导致的温度骤升或传感器漂移/卡死现象。",
    "4. **综合判断**：结合时间窗口（下午时段）、设备操作逻辑（洗碗机正常工作）和人员分布（仅玄关有活动，其余区域空置），所有事件均在正常生活行为范围内，无入侵、火灾或设备故障风险。"
  ],
  "key_evidence": [
    "kitchen_dishwasher OperationalState 从 1 变为 0，中间包含 CountdownTime 设置，符合正常洗涤流程。",
    "entrance_occupancy 间歇性为 1，而 living_room/master_bedroom/second_bedroom occupancy 持续为 0，排除非法入侵特征。",
    "全屋温度传感器数值稳定在舒适区间，无剧烈波动。"
  ],
  "recommended_actions": [
    "无需采取紧急安全措施。",
    "建议继续监控洗碗机后续是否完成排水及烘干阶段的状态更新，以确保完整循环结束。"
  ]
}
```

Rejected response:

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。

  "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
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",

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
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",

    "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": [

  ]
}

Rejected response:
```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "检测到厨房灶具在无人看管的情况下长时间开启，且伴随温度异常升高，存在极高的火灾风险。",
  "reasoning": [
    "推理步骤 1: 日志显示在 2026-08-25T12:05:00 时，厨房灶具 (kitchen_cook_surface) 被开启 (OnOff = True)。",
    "推理步骤 2: 随后在 12:12:00，厨房温度传感器读数从正常的约 25°C (2533 mK) 急剧飙升至 29.2°C (2920 mK)，表明热源正在持续加热环境。",
    "推理步骤 3: 关键风险在于，灶具开启后直到日志结束（12:16:00），没有任何记录显示灶具被关闭或住户离开厨房区域（尽管有入户门和客厅的占用信号，但缺乏明确的‘人离开厨房’与‘关闭灶具’的关联动作）。对于独居老人而言，忘记关火是极高风险的行为模式。",
    "推理步骤 4: 虽然厨房烟雾报警器未在日志中触发报警，但这可能是因为采样频率未覆盖到报警瞬间，或者处于测试/故障状态，不能排除火灾隐患。"

    "灶具开启后无关闭事件记录，且持续时间较长"
  ],
  "recommended_actions": [
    "立即远程通知住户或紧急联系人，确认是否有人在家并检查厨房安全。",
    "如果无法联系到住户且系统检测到温度继续上升或烟雾传感器触发，应自动拨打当地紧急服务电话。",
    "建议检查厨房烟雾报警器和温度传感器的校准状态，确保其正常工作。",
    "考虑为独居老人配置智能灶具防干烧/超时自动断电功能。"

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: 正常余热会逐步回落；异常样本在关火后温度继续上升。"
  ],
  "key_evidence": [
    "正常余热会逐步回落；异常样本在关火后温度继续上升。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:

  "threat_description": "厨房灶具在无人看管的情况下长时间运行，且随后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: 行为模式分析显示，用户在 18:30 开启厨房灯和灶具，但在 19:20 关闭了灶具。然而，从 19:20 到 19:25（仅 5 分钟），厨房温度传感器读数从正常的约 23°C (2300 mK) 瞬间跳变至 28.6°C (2860 mK)，并在 19:35 进一步升至 27.4°C (2740 mK)。这种升温速率远超正常烹饪结束后的余热衰减速度，表明可能有明火复燃、燃气泄漏燃烧或设备故障导致的高温积聚。",
    "推理步骤 2: 人员状态与设备状态不匹配。日志显示在 19:20 关闭灶具后，直到 19:35 之前，客厅、主卧、次卧的 occupancy 传感器均检测到有人活动（Occupancy=1），但厨房区域没有明确的 Occupancy 报告（或默认视为无直接关联的高频占用确认）。更关键的是，如果用户正在家中其他房间活动，而灶具在关闭后迅速产生高温，这属于典型的‘未受监控烹饪’或‘操作失误’场景。",
    "推理步骤 3: 数据异常性验证。Matter 协议中温度通常以毫开尔文 (mK) 为单位，2300 对应 23°C，2860 对应 28.6°C。虽然 28.6°C 本身不是致命高温，但结合上下文：灶具刚关闭，温度却出现非线性的剧烈波动（先升后降但仍高于初始值），且伴随之前的多次短暂启停（18:30-18:59, 19:00-19:20），这表明烹饪过程极其不稳定，极有可能是油锅起火初期被扑灭后复燃，或者传感器因靠近火源/热浪而受到干扰。考虑到烟雾报警器未在日志中触发报警事件，可能存在延迟或尚未达到阈值，但这已是严重的前兆。"
  ],
  "key_evidence": [
    "19:20 关闭灶具后，5 分钟内厨房温度传感器读数从 ~2300 飙升至 2860 (28.6°C)，升温速率异常。",
    "19:35 温度读数再次变化至 2740，显示持续的热异常状态，而非正常冷却。",
    "烹饪期间存在多次短暂的开关操作（18:30-19:20），增加了操作失误或火势失控的概率。"

  "recommended_actions": [
    "立即通知住户前往厨房检查是否有明火、烟雾或燃气泄漏。",
