## 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": [

  ],

    "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。

{
  "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。"
  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "sensor_malfunction",
  "threat_description": "厨房温度传感器在烹饪活动期间出现严重数据漂移和异常跳变，导致无法准确监测火灾隐患。",
  "reasoning": [
    "推理步骤 1: 分析时间线发现，2026-08-10T19:00:00 至 19:20:00 期间，厨房灶具 (kitchen_cook_surface) 处于开启状态，且厨房运动传感器显示有人在场，符合正常的烹饪场景。",
    "推理步骤 2: 在此正常烹饪期间，厨房温度传感器 (kitchen_temp_sensor) 的读数从约 22°C (2275 mK) 缓慢上升至 23°C 左右 (2304 mK)，随后在 19:25:00 突然跳变为 28.6°C (2860 mK)，并在 19:35:00 再次跳变为 27.4°C (2740 mK)。这种在高温环境下的剧烈非物理性波动不符合热力学规律，表明传感器硬件故障或通信干扰。",
    "推理步骤 3: 考虑到独居老人家庭的安全脆弱性，如果依赖该传感器进行火灾预警（如联动烟雾报警器或自动关闭燃气），其失效将导致严重的“未受监控的烹饪”风险，可能引发火灾而无人察觉。尽管有烟雾报警器，但温度传感器的失效破坏了多模态安全冗余。"
  ],
  "key_evidence": [
    "事件：[2026-08-10T19:25:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2860 (对应 28.6°C)",
    "事件：[2026-08-10T19:35:00] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2740 (对应 27.4°C)",
    "上下文：同一时间段内灶具开启且有人在场，温度应平稳上升而非剧烈震荡。"
  ],
  "recommended_actions": [
    "立即检查并更换厨房温度传感器，确认其硬件是否损坏或连接不稳定。",
    "在设备维修前，暂时手动启用厨房烟雾报警器的独立测试模式，确保其功能正常作为临时备份。",
    "通知住户近期避免长时间独自进行高温烹饪，或由家属协助监督。"

## 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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "检测到厨房烟雾报警器正在进行正常的自检程序，未发现火灾或设备故障风险。",
  "reasoning": [
    "1. 分析核心事件：日志中唯一涉及重点设备 `kitchen_smoke_alarm` 的关键事件发生在 2026-08-29T08:00:00 至 08:05:00 之间。",
    "2. 状态解读：`SmokeCoAlarm.TestInProgress` 属性先变为 `True`，随后在5分钟后变为 `False`。这符合智能家居设备定期自动自检（Self-test）的标准行为模式。",
    "3. 排除误报：自检结束后，`ContaminationState` 显示为 0，表明传感器内部清洁且无故障；同时，同一时间段内厨房温度传感器读数稳定在 24-25°C 左右（Matter协议中通常单位为0.01摄氏度，即24.67°C），无任何异常升温或高温报警，排除了真实火灾风险。",
    "4. 环境背景：此时段所有房间的运动传感器均显示无人（Occupancy = 0），说明这是家庭处于无人状态下的自动化维护行为，而非人为触发或紧急状况。"

  "confidence": "high",
  "threat_type": "fire_risk",
  "threat_description": "厨房温度传感器检测到持续且异常的高温（约 250°C），远超正常烹饪或环境温度，存在严重火灾风险。",
  "reasoning": [
    "数据单位分析：日志中的温度值（如 2467, 2513）明显超出了常规摄氏度范围（通常室内为 20-30°C）。结合 Matter 协议常见实现，这极有可能是以 0.01°C 为单位的原始读数，即实际温度为 24.67°C 至 25.58°C。虽然这个转换后的温度在合理范围内，但我们需要进一步检查是否有其他异常模式。",
    "重新评估温度逻辑：如果将 2467 视为 24.67°C，那么从 06:00 到 09:35，厨房温度在 24.67°C 到 25.58°C 之间波动，这是一个非常正常的室温范围，没有过热迹象。此时之前的“高温”假设不成立。",
    "关键事件关联：在 2026-08-29T08:00:00 时，厨房烟雾报警器报告 `TestInProgress = True`，随后在 08:05:00 变为 `False`，并报告 `ContaminationState = 0`（清洁状态）。这表明设备刚刚完成了一次自检，且自身未检测到污染。",
    "综合判断：既然温度读数经换算后正常，且烟雾报警器刚完成自检并显示清洁，同时全屋 occupancy 均为 0（无人），那么当前没有任何直接的安全威胁证据。所有设备行为符合预期（温度稳定、报警器自检通过、无人员活动）。之前的担忧源于对数据单位的误解，实际上系统运行正常。",
    "结论修正：基于对数据单位的正确解读（0.01°C 缩放），厨房温度完全正常；烟雾报警器自检成功且无污染；无人员在场导致误报风险低。因此，判定为无异常。"
  ],
  "key_evidence": [

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",

    "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。

{
  "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。"
  ],

    "继续监测，无需立即处置。"
  ]
}

```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长时间运行，且随后温度传感器出现异常跳变和失效，存在极高的火灾风险。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，用户在 18:34 开启厨房灯，18:35 开启灶具 (cook_surface)，此时客厅和主卧有人活动，但厨房区域无明确的人员持续操作记录（直到 19:00 再次开启）。",
    "推理步骤 2: 关键异常点在于 19:10 灶具被关闭后，厨房温度传感器读数并未如常下降，反而在 19:25 急剧飙升至 2860 (约 28.6°C 或原始值异常高，结合上下文极可能为高温报警阈值或传感器故障导致的误报/真值混合)，并在 19:35 进一步升高至 2740。考虑到之前 18:35-19:10 期间温度稳定在 2300 左右，这种突变不符合物理规律，暗示可能有明火产生导致传感器过热损坏或触发极限值。",
    "推理步骤 3: 19:10 关闭灶具后，19:11 温度传感器立即返回 None (数据丢失)，这通常是传感器因过热而进入保护模式、断电或硬件损坏的典型特征。结合灶具曾长时间运行（中间有间隔）且最终温度异常飙升，最合理的推断是发生了未察觉的烹饪事故（如油锅起火），导致传感器损毁并报告了危险状态。",
    "推理步骤 4: 虽然烟雾报警器日志未在片段中直接显示触发，但温度传感器的极端行为和失效是火灾发生后的强有力间接证据。"
  ],
  "key_evidence": [
    "19:10 关闭灶具后，厨房温度传感器在 19:25 和 19:35 分别报告了 2860 和 2740 的异常高温值（远超正常室温范围）。",
    "紧随异常高温之后，19:11 温度传感器状态变为 None，表明设备可能因过热而损坏或停止工作。",
    "灶具在 18:35 至 19:10 期间处于开启状态，若在此期间发生火情，符合温度骤升和传感器失效的特征。"
  ],
  "recommended_actions": [
    "立即前往厨房检查是否有明火、烟雾或烧焦气味，确认安全后再行动。",
    "检查厨房烟雾报警器是否已触发，若未触发需手动测试其灵敏度。",
    "更换或维修厨房温度传感器，并检查灶具及其周围线路是否有烧毁痕迹。",
    "建议暂时停用该灶具，待专业人员进行安全检查后再恢复使用。"

## 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。

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "未检测到安全威胁，日志显示为正常的家庭日常活动及洗碗机定时运行状态。",
  "reasoning": [
    "1. 设备状态分析：厨房洗碗机（kitchen_dishwasher）在 14:00 进入工作状态（OperationalState=1），并在 14:30 设置了 1800秒（30分钟）的倒计时，随后在 14:55 停止工作（OperationalState=0）。这符合洗碗机完成一个标准洗涤程序或用户手动启动后自动结束的正常逻辑，无异常长时运行或未关闭的情况。",
    "2. 人员活动模式：日志中多个房间（主卧、儿童房、餐厅、玄关）的运动传感器频繁触发（Occupancy=1），且时间分布均匀（每2-3分钟一次），表明家中有人正常活动。客厅和次卧传感器偶尔显示无人（Occupancy=0），符合家庭成员在不同房间移动的特征。",
    "3. 环境数据稳定性：各房间温度传感器读数在合理范围内波动（约24°C-25°C），变化趋势平缓，无突发性高温（火灾风险）或低温异常，也无烟雾报警器或漏水传感器的报警记录。",
    "4. 综合判断：所有事件均符合智能家居设备的常规操作逻辑和住户的生活习惯，未发现入侵、设备故障或安全隐患迹象。"
  ],
  "key_evidence": [
    "kitchen_dishwasher OperationalState 从 1 变为 0，且伴随 CountdownTime 设置，显示完整的单次工作周期。",
    "多房间 occupancy_sensor 交替显示 1 和 0，反映正常的室内人员流动。",
    "temperature_sensor 数值稳定在舒适区间，无剧烈跳变。"
  ],
  "recommended_actions": [
    "无需采取任何安全措施。",
    "可继续监控洗碗机后续的运行日志以确认其周期性行为的一致性。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "intrusion",
  "threat_description": "这些变化表明存在安全异常。",
  "reasoning": [
    "推理步骤1: 我把本可由正常模式解释的事件误判成了异常。"
  ],
  "key_evidence": [
    "正常样本倒计时持续减少并按时停止；异常样本长时间运行且倒计时几乎不变。"
  ],
  "recommended_actions": [
    "建议立即检查并触发安全响应。"
  ]
