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",

  ],
  "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。

    "推理步骤 2: 观察异常数据的时序特征，发现不同房间（客厅、主卧、厨房等）的传感器在同一时间点几乎同时更新并呈现高度相关的数值变化（例如 01:20 时全部跳变至 23xx 区间）。这种跨设备的同步‘漂移’排除了局部热源导致的可能性，指向系统性的数据读取错误或校准失效。",
    "推理步骤 3: 结合 occupancy 传感器状态，虽然检测到有人进入主卧和开门事件，但并未伴随任何烟雾报警器（smoke_co_alarm）的触发或漏水报警。如果真实温度达到如此高温，安全设备必然已响应。因此，判定为传感器数据漂移（Sensor Drift）而非真实的火灾风险，需优先修复传感器以避免误报或掩盖真实隐患。"

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。

  "reasoning": [
    "推理步骤 1: 分析日志发现，在 2026-08-09T12:15:00 时，厨房温度传感器报告值为 2643 (即 26.43°C) 的原始数据点，随后在 T12:20:00 跳变至 2597 (25.97°C)，但在 T12:15:00 之前的上下文显示该设备正在监测烹饪区域。更关键的异常在于数值本身：如果单位是毫摄氏度 (mCelsius)，2643 mC = 2.643°C，这在夏季室内不可能；如果单位是摄氏度，2643°C 会导致火灾报警立即触发且设备损坏。结合 Matter 协议常见整型编码习惯，此处极可能是传感器将 '26.43' 误报为 '2643' 或者传感器硬件故障导致数值溢出/漂移。",
    "推理步骤 2: 对比同一时间段的其他传感器数据，客厅和卧室的温度读数均在 23-25°C 之间波动，符合正常室温范围。唯独厨房传感器在 12:15 出现孤立的高位异常峰值，随后迅速回落但仍高于正常水平，这种非线性的剧烈跳变不符合人体活动或环境温度自然变化的规律。",
    "推理步骤 3: 虽然存在 unattended_cooking 的风险（因为灶具未明确关闭状态日志，但温度异常通常伴随高温），但首要问题是数据来源本身的不可信。基于一个明显故障的传感器做出的“有人忘记关火”判断属于误报。因此，核心威胁类型应归类为 sensor_malfunction（传感器故障/漂移），而非直接的安全入侵或火灾风险。"

    "厨房温度在 12:15 至 12:20 期间呈现无规律的剧烈波动（2643 -> 2597 -> 2515），缺乏与环境热源（如炉灶）持续加热相匹配的平滑上升曲线，符合传感器噪声或故障特征。"

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": [
    "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: 正常入户会伴随门磁、玄关灯或入口相关活动；异常样本只有解锁结果和室内后续活动。"
  ],
  "key_evidence": [
    "正常入户会伴随门磁、玄关灯或入口相关活动；异常样本只有解锁结果和室内后续活动。"
  ],
  "recommended_actions": [
    "继续监测，无需立即处置。"
  ]
}

Rejected response:
```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丢失，读数异常偏高且频繁变为 None，导致无法准确监测火灾风险。",
  "reasoning": [
    "推理步骤 1: 日志显示住户于 18:45 开启灶具 (cook_surface)，随后厨房温度传感器读数从正常的 20-30°C 范围急剧上升至 2700+ (如 2712, 2709, 2655)。考虑到 Matter 协议中温度通常以 0.01°C 为单位，这些数值（例如 2712）远超物理极限，属于明显的传感器故障或数据溢出。",
    "推理步骤 2: 在 18:46 和 19:28 等关键时间点，该传感器报告值为 None，表明设备通信中断或内部逻辑错误，导致安全监控盲区。",
    "推理步骤 3: 尽管其他房间温度正常，但厨房作为火灾高发区，其核心安全传感器失效构成了高风险隐患。虽然最终灶具已关闭且窗户未打开，但传感器本身的不可靠性必须被标记为异常。"

  "key_evidence": [

    "2026-08-05T18:46:00 kitchen_temp_sensor: MeasuredValue = None (数据丢失)",
    "2026-08-05T19:28:00 kitchen_temp_sensor: MeasuredValue = None (数据丢失)"
  ],
  "recommended_actions": [
    "立即检查并更换厨房温度传感器，确认硬件是否损坏或校准失败。",
    "在修复前，建议用户手动定期检查厨房区域是否有过热迹象，或暂时启用非智能的独立烟雾报警器作为备份。",
    "审查 Matter 网络日志，排除因信号干扰导致的传感器数据包解析错误。"
