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
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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。

    "2. 关联上下文分析：在自检开始前（07:01-07:03），厨房灶具曾短暂开启后关闭，随后温度传感器读数虽有波动但处于正常室温范围（约24-25°C），并未出现因烹饪导致的急剧升温或烟雾积聚迹象。",
    "3. 排除误报可能：烟雾报警器的 'TestInProgress' 属性明确指示这是计划内的维护或自检行为，且最终状态恢复正常，没有伴随 'SmokeDetected' 或 'COAlarm' 等危险状态标志。因此，这属于正常设备行为，不构成安全威胁。"

## 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",

  ],
  "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。

    "2. 排除误报/故障：TestInProgress 状态通常由用户手动触发（如按下测试按钮）或系统定期自动执行自检程序。日志中未伴随温度急剧升高、湿度异常或烟雾浓度报警（SmokeLevel/COCLevel），且仅持续约4分钟即结束，符合自检特征而非真实火情。",
    "3. 结合环境背景：同一时间段内，客厅、主卧、儿童房等区域的 occupancy_sensor 显示有人活动（Occupancy=1），且温度传感器读数稳定在 25-26°C 左右，无剧烈波动，表明家庭环境处于正常生活状态，无紧急撤离迹象。",

    "2. 分析环境数据关联：厨房温度传感器数据显示温度从 13:00 的 27.45°C 持续下降至 15:15 的 24.24°C。这种降温趋势通常由空调开启或开窗通风引起。考虑到客厅和卧室 occupancy 传感器多次报告有人 (Occupancy=1) 或无人 (Occupancy=0) 的状态变化，且客厅 occupancy 在洗碗机运行时保持为 1，推测住户可能在客厅活动并开启了空调，导致整体室温（包括厨房）下降。",

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。

    "推理步骤 2: 结合 occupancy 数据判断人员在场情况。虽然 18:16-18:45 期间客厅、主卧、玄关有活动记录，但关键时间点 19:00 至 19:20 之间，除了 19:06 主卧有人外，没有明确的厨房区域持续占用记录（尽管无法直接证明厨房无人，但频繁开关暗示可能无人值守或操作混乱）。更关键的是，19:20 关闭灶具后，温度并未立即回落至安全范围。",
    "推理步骤 3: 分析温度传感器数据。在 19:20 关闭灶具后，温度读数出现剧烈且无规律的波动：从正常的 ~2290 跳变到 2860 (19:25)，随后又跳变到 2740 (19:35)，最后才回到 2274。这种在高温关闭后的‘余温’阶段出现的非单调下降的剧烈震荡，极有可能是烟雾报警器触发导致温度传感器读数异常，或者是燃烧物未完全熄灭导致的复燃迹象，属于典型的火灾隐患前兆。"

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
请根据以下设备记录评估当前是否需要安全响应；若需要，请说明原因与处置建议。

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: ...",

    "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_description": "检测到烟雾报警器正在进行自检（TestInProgress），属于正常的设备维护行为，未检测到真实火灾或故障风险。",
  "reasoning": [
    "1. 识别关键事件：日志显示在 10:00:00 和 10:01:00，厨房和客厅的烟雾报警器分别上报了 SmokeCoAlarm.TestInProgress = True 的状态。",
    "2. 验证状态闭环：在 10:04:00，厨房烟雾报警器上报 TestInProgress = False，表明测试流程已正常结束。虽然客厅报警器的结束状态未在片段中显示，但开始时间接近且通常此类测试是批量或同步进行的，符合预期逻辑。",
    "3. 排除误报：TestInProgress 是 Matter 协议中用于指示设备正在执行自我诊断的标准属性，并非 SmokeDetected（检测到烟雾）或 AlarmActive（警报激活）。结合此时段家中有多人活动（餐厅、儿童房、主卧、玄关均有 Occupancy=1 记录），排除了无人值守导致的设备异常或故障未被发现的情况。",
    "4. 结论：这是用户主动触发的或系统计划内的安全设备自检，属于正常运维行为，无需紧急安全响应。"

## 任务
系统刚记录到以下一段设备状态变化。请评估这些变化是否已经构成安全风险，并说明原因。

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": [
    "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

  "confidence": "high",

  "threat_description": "未检测到安全风险，日志显示为正常的设备运行状态及住户活动模式。",
  "reasoning": [
    "1. 洗碗机状态分析：日志显示厨房洗碗机在 14:00 进入工作状态 (OperationalState=1)，并在 14:30 设置倒计时 1800秒（30分钟），随后在 14:55 停止工作 (OperationalState=0)。这符合标准的洗碗机洗涤周期逻辑，且任务结束后有人工或自动干预停止，不存在无人看管导致的溢出或故障风险。",
    "2. 温度传感器数据合理性：厨房温度传感器读数从 25.2°C 缓慢下降至约 24.4°C。这种变化速率（约 0.8°C/小时）属于室内环境温度自然波动范围，可能是由于空调开启、开窗通风或烹饪余热消散所致，并非传感器故障或极端环境异常。",
    "3. 人员活动与设备联动逻辑：主卧和玄关的运动传感器在下午时段持续检测到存在 (Occupancy=1)，表明家中有住户活动。结合洗碗机的正常运行，没有发现入侵迹象（如门锁异常开启）、火灾风险（烟雾报警器无报警）或漏水等紧急情况。"
  ],
  "key_evidence": [
    "kitchen_dishwasher OperationalState 从 1 变为 0，且中间有 CountdownTime 记录，符合正常洗涤流程。",
    "kitchen_temp_sensor 温度值呈平缓下降趋势 (2520 -> 2442)，无剧烈跳变。",
    "entrance_occupancy 和 master_bedroom_occupancy 显示住户在家，排除了离家期间的异常入侵可能。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续监控洗碗机后续是否完全断电以确认程序彻底结束。"
  ]
}
```

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。
