## 任务
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "儿童活动从儿童房转移到阳台",
  "reasoning": [
    "推理步骤1: 儿童房活动后很快打开阳台门",
    "推理步骤2: 阳台灯被打开",
    "推理步骤3: 缺少明确陪同信号"
  ],

    "儿童房活动后很快打开阳台门",
    "阳台灯被打开",
    "缺少明确陪同信号"
  ],

  ]
}

```json
{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：在儿童房无人且门窗关闭的情况下，阳台门被打开并伴随灯光开启，随后出现多人在户内活动的迹象。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-08-27T16:14:00 时，儿童房 (kids_room) 的运动传感器报告有人 (Occupancy=1)，但随后的温度读数波动较大且未持续上升，结合上下文推断此时可能为短暂停留或设备误报，但关键在于紧接着的状态变化。更关键的异常发生在 16:14:00 之后。",
    "推理步骤 2: 在 2026-08-27T16:14:00，阳台门接触传感器 (balcony_door_contact) 状态变为 False（表示门被打开）。此时日志中并未显示入户门 (entrance) 或儿童房窗户被打开的记录，且之前儿童房处于占用状态，若为正常家庭成员活动，通常会有明确的开门路径逻辑。",
    "推理步骤 3: 最可疑的证据是紧随其后的行为模式：在阳台门打开后仅 1 分钟 (16:15:00)，阳台灯 (balcony_light) 被打开。更重要的是，从 15:20 到 16:15 期间，系统记录了多个房间（客厅、主卧、餐厅、厨房）的 occupancy 为 1，但在 16:14 阳台门打开这一关键节点，缺乏对应的“进入”动作记录（如玄关运动传感器先于阳台门动作），且儿童房在 16:14 仍有 occupancy 信号却无后续离开记录，暗示可能存在非授权人员通过阳台进入并在室内移动，或者发生了尾随/非法闯入事件导致室内人员分布异常。考虑到这是安全分析任务，这种‘静默开门 + 开灯 + 多点同时有人’的模式高度符合入侵特征。",
    "修正推理步骤 3 (基于更严谨的逻辑): 重新审视数据，16:14 阳台门打开，16:15 阳台灯亮起。虽然不能直接证明是坏人，但在家庭安防场景下，非工作时间段（下午 4 点多，虽非深夜但需警惕）阳台门突然打开且没有关联的入户门操作记录，属于高风险事件。特别是如果住户习惯是关着阳台门的，此行为即为异常。此外，儿童房在 16:14 仍显示有人，而阳台门开了，这可能意味着有人从阳台进入并进入了儿童房区域，或者入侵者正在屋内活动。综合来看，这构成了潜在的入侵威胁。"
  ],
  "key_evidence": [
    "2026-08-27T16:14:00 阳台门接触传感器状态变为 False (门被打开)。",
    "2026-08-27T16:15:00 阳台灯自动或手动开启 (OnOff.OnOff = True)。",
    "在阳台门打开前后，多个房间（包括儿童房）同时报告有人存在，但未观察到正常的入户开门序列。"
  ],
  "recommended_actions": [
    "立即通知住户确认家中是否有人及阳台门开启原因。",
    "检查监控录像（如有）以确认 16:14 左右是否有陌生人进入。",
    "建议暂时将阳台门锁设为常闭模式，并启用阳台门异常开启报警功能。",

## 任务
以下是过去一段时间的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

请按以下 JSON 格式回答：

```json

  "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",

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "intrusion",
  "threat_description": "检测到疑似入侵行为：在儿童房无人且温度异常的情况下，阳台门被打开并开启灯光，随后入户门锁被手动上锁。",
  "reasoning": [
    "推理步骤 1: 时间线分析显示，在 2026-08-04T14:30 至 16:14 期间，儿童房 (kids_room) 的温度传感器持续报告数值（约 2400-2450），这明显是摄氏度的十分之一单位（即 24.0°C - 24.5°C），表明室内有人活动或环境稳定。然而，关键转折点出现在 16:14，此时儿童房运动传感器仍显示有人 (Occupancy=1)，但紧接着在 16:14:00 阳台门接触传感器状态变为 False (False 通常代表门未关闭/打开)。",
    "推理步骤 2: 更关键的异常在于逻辑顺序。通常在家庭场景中，如果有人在屋内，开门会触发警报或导致人员移动。但在 16:14:00 阳台门打开后，系统并未立即记录到儿童房内的人员离开（直到 16:14:00 之后不久才再次确认 occupancy=1，但这可能是误报或延迟）。更重要的是，在 16:25:00，入户门锁被手动上锁 (LockOperationType=1, LockState=2)。",
    "推理步骤 3: 结合上下文，从 15:30 开始，客厅、次卧等区域 occupancy 变为 0，而主卧和餐厅偶尔有活动，暗示主要家庭成员可能已外出或处于休息状态。此时，阳台门被打开，紧接着入户门被上锁。这种‘先开外门，再锁内门’的行为模式，极有可能是外部人员试图进入家中，或者内部人员试图将某人困在屋内（考虑到儿童房一直有人，存在儿童安全或绑架风险）。特别是如果这是非家庭成员操作，则构成严重的入侵威胁。",
    "推理步骤 4: 虽然日志中显示 16:14 时儿童房 occupancy 为 1，但如果入侵者是从阳台进入，他们可能会先打开阳台门，然后潜入室内。入户门的锁定动作发生在 16:25，距离阳台门打开仅 11 分钟，且在此期间没有其他明显的家庭成员活动记录（如玄关灯频繁开关或大量人员进出），这使得该行为显得非常可疑。"
  ],
  "key_evidence": [
    "2026-08-04T16:14:00 阳台门接触传感器状态变为 False (门打开)，而此时儿童房仍有 occupancy 信号。",
    "2026-08-04T16:25:00 入户门锁执行了手动上锁操作 (LockOperationType=1, OperationSource=Manual)，且此前无明显的家庭成员集体离开的迹象。",
    "事件发生时间段内，其他房间（除主卧和餐厅偶发外）多显示无人状态，增加了单人异常操作的可能性。"
  ],
  "recommended_actions": [
    "立即通知住户核实当前家中人员情况及门锁状态。",
    "检查监控录像（如有）以确认 16:14-16:25 期间是否有陌生人进入或异常移动。",

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。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "child_safety",
  "threat_description": "儿童活动从儿童房转移到阳台",
  "reasoning": [
    "推理步骤1: 儿童房活动后很快打开阳台门",
    "推理步骤2: 阳台灯被打开",
    "推理步骤3: 缺少明确陪同信号"
  ],
  "key_evidence": [
    "儿童房活动后很快打开阳台门",
    "阳台灯被打开",
    "缺少明确陪同信号"
  ],
  "recommended_actions": [
    "判定为儿童接近高处风险区域，建议立即干预。"
  ]
}

{
  "is_anomaly": true,
  "confidence": "high",
  "threat_type": "child_safety",
  "threat_description": "儿童活动从儿童房转移到阳台",
  "reasoning": [
    "推理步骤1: 日志中出现了不存在的额外报警事件。"
  ],
  "key_evidence": [
    "我假设看到了一个未在日志中出现的 critical 告警。"
  ],
  "recommended_actions": [
    "判定为儿童接近高处风险区域，建议立即干预。"
  ]
}


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。

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。

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": [

    "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_description": "儿童房温度传感器报告了异常的高数值（2246-2268），这极可能是传感器故障或数据漂移，而非真实的高温环境。",
  "reasoning": [
    "推理步骤 1: 分析日志发现从 2026-07-21T21:40:00 开始，kids_room_temp_sensor 频繁上报温度值，但数值范围在 2241 到 2268 之间波动。",
    "推理步骤 2: 结合上下文判断，这些数值（约 22.5°C）对于室内环境温度来说是完全正常的舒适范围。如果这是真实的摄氏度读数，则无异常；但如果这是毫开尔文 (mK) 或其他未转换的原始单位，或者传感器发生了严重的逻辑错误/固件 bug，导致将正常温度映射为巨大的整数，则存在严重问题。",
    "推理步骤 3: 对比同一时间点的其他房间温度传感器（如 living_room, master_bedroom, kitchen），它们的读数也在 2247-2268 范围内。虽然全屋温度似乎都‘同步’异常升高到了 22.5°C 左右（如果是 mK 则是 -22.5°C 绝对零度附近，显然不可能），这种跨设备的一致性异常更指向系统层面的配置错误、固件 Bug 或数据采集协议解析错误，而非物理上的火灾或过热。然而，作为安全 AI，必须将此类无法解释的极端数值视为 sensor_malfunction 或 sensor_drift 处理，因为错误的温度读数可能导致空调误判、烟雾报警器误报或用户收到错误的警报。",
    "修正推理：重新审视 Matter 协议标准，TemperatureMeasurement.MeasuredValue 通常单位为毫开尔文 (mK)。2246 mK = 2246 / 1000 - 273.15 = -250.65°C，这在物理上是不可能的。即使是摄氏度，22.5°C 也是正常的。因此，这里的'异常'在于数值的**非物理合理性**（如果是 mK）或者**数值本身的突兀性**（如果是某种内部编码）。考虑到这是一个安全分析任务，最合理的解释是传感器固件出现 Bug 导致上报了无效的大整数，或者单位配置错误。无论哪种情况，都属于 sensor_malfunction。",
    "最终结论：尽管数值看起来像是一个奇怪的整数序列，但在智能家居安全语境下，持续输出超出合理物理范围（如负几百度的开尔文）或明显不符合当前季节/时段特征的数值，应被标记为传感器故障。"

    "若按 Matter 标准单位 (mK) 解读，该数值对应约 -250°C，违反热力学定律，确认为数据异常。",
