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",

  ],

}
```

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。

  "reasoning": [
    "推理步骤 1: 时间线分析显示，厨房灶具 (kitchen_cook_surface) 于 07:09:36 开启，但在 11:00:00 时客厅运动传感器报告无人在场 (Occupancy=0)，随后直到 12:05:00 才再次有人进入并开启灶具。这意味着从早上 7 点到中午 12 点期间，灶具处于无人看管状态长达约 5 小时。",
    "推理步骤 2: 温度数据异常。正常室温约为 22-25°C (日志中数值如 2280 代表 22.80°C)。然而，在 12:12:00，厨房温度传感器读数飙升至 29.20°C (2920)，远高于之前的 25°C 左右，且此时灶具已关闭或处于高风险冷却阶段（若未关则更危险）。这种急剧升温表明可能存在设备故障、燃气泄漏导致的局部过热或传感器被遮挡/损坏，无法准确反映真实环境温度，但结合长时间无人看管的烹饪行为，火灾风险极高。",
    "推理步骤 3: 行为模式矛盾。住户习惯通常不会让灶具运行数小时而不进行任何操作或离开房屋。长时间的无人看管烹饪是典型的火灾隐患场景，加上温度读数的剧烈波动，系统应判定为高危事件。"
  ],

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。

    "2. 离家与安防状态：07:46 左右，主卧灯和厨房灯熄灭，入户门锁执行了手动上锁操作（LockState=2），随后门磁传感器显示门已关闭（StateValue=True）并立即重新上锁（LockState=1）。这一系列动作高度一致，表明住户正在有序离家，不存在入侵或尾随迹象。玄关运动传感器在 07:46 和 08:26 的激活也符合人员进出或在家活动的特征。",
    "3. 设备自检行为：08:00 至 08:05，厨房烟雾报警器触发了 'TestInProgress' 状态，并在 5 分钟后恢复正常且污染状态为 0。这是标准的设备自检或维护行为，并非真实火警或故障，属于正常系统运行的一部分。",

    "推理步骤 2: 在 06:52 分，日志显示厨房灶具 (cook_surface) 状态为关闭 (False)，但在 29 秒后再次变为开启 (True)。这种短时间内反复开关的行为模式不符合正常烹饪习惯，更像是设备故障或人为误操作导致的持续加热。",

## 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：

  "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。

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

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 1: 在 12:05:00，厨房灶具 (kitchen_cook_surface) 被开启，随后在 12:10:00 厨房温度传感器读数为 25.20 (即 25.20°C)，处于正常室温范围。",
    "推理步骤 2: 仅仅在 30 秒后的 12:12:00，同一传感器的读数突然变为 2920 (即 29.20°C)。虽然数值本身仍在合理范围内，但考虑到这是 Matter 协议日志，通常此类极端跳变（如从 25xx 到 29xx）可能代表传感器校准丢失、硬件故障或受到强电磁干扰导致的误报，而非真实的物理升温（真实升温需要时间积累）。",
    "推理步骤 3: 结合上下文，如果这是一个真实的火灾风险事件，温度应持续上升并伴随烟雾报警；而此处仅有一个孤立的异常高值点，随后在 12:20:00 又回落至 25.27°C。这种‘尖峰’模式更符合传感器 malfunction（故障）或 drift（漂移），而非真实的火灾威胁。然而，由于涉及高温设备（灶具）和异常读数，必须将其视为潜在的安全隐患进行最高优先级处理，以防是真实过热被错误记录或传感器即将失效导致无法监测真实高温。",
    "修正推理：重新审视数据，2920 对应 29.2°C。对于刚开火的灶具，30 秒内升高 4 度是可能的，但紧接着在 12:20 就完全恢复正常（25.27°C），这在物理上极不可能（除非火瞬间熄灭且冷却极快，但这与用户行为逻辑不符）。因此，最合理的解释是 **sensor_malfunction** 导致了虚假的高温读数，或者该传感器已损坏。尽管主要问题是传感器故障，但在安全分析中，针对高温设备的传感器故障属于 **safety_device_failure** 或潜在的 **fire_risk** 前兆（因为如果传感器坏了，它可能在真正着火时也不报警）。鉴于任务选项中有 sensor_malfunction，且现象最符合此定义，但为了强调其对安全的威胁性质，归类为 fire_risk 的预警更为妥当，或者明确指出是 sensor_malfunction 导致的 fire_risk 风险。根据提供的选项列表，'sensor_malfunction' 是最准确的根本原因描述，但 'fire_risk' 是后果。让我们选择最能反映当前状态风险的类型。实际上，如果传感器坏了，我们无法确认是否有火，所以风险极高。这里选择 **sensor_malfunction** 作为直接原因，因为它解释了数据的矛盾性。",
    "最终决策：虽然根本原因是传感器故障，但该故障发生在正在使用的灶具旁，构成了严重的安全隐患。在威胁分类中，这通常被视为 **sensor_malfunction**（导致监控失效）或 **fire_risk**（因监控失效带来的风险）。考虑到数据表现出的“假阳性”高温，**sensor_malfunction** 是最客观的描述。"

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
请分析下面的实时设备事件，判断是否需要将其视为异常安全事件。

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: ..."

    "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。

  "threat_type": "none",
  "threat_description": "检测到厨房烟雾报警器正在进行正常的自检/测试流程，无真实火灾或故障风险。",
  "reasoning": [
    "1. 识别关键事件：在 08:00:00 和 08:05:00，日志显示 kitchen_smoke_alarm 的 SmokeCoAlarm.TestInProgress 状态从 True 变为 False，且 ContaminationState 为 0（正常）。这表明设备执行了一次完整的自检程序。",
    "2. 排除火灾风险：虽然重点设备是烟雾报警器，但在整个时间窗口内（06:50 - 08:35），没有任何报警触发记录（如 AlarmState 变化），且温度传感器读数稳定在 24-25°C 左右，没有急剧升温迹象，排除了真实火灾可能。",
    "3. 结合住户行为：07:36 左右有人通过入户门离开（门锁手动操作，门磁关闭后重新打开并上锁），随后家中其他区域（餐厅、儿童房）有人员活动迹象。早晨时段进行设备自检符合常规维护习惯，且测试期间无误报，说明设备功能正常。"
