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 3 天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: ..."
  ],

    "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": "未检测到安全威胁或异常模式，所有设备状态变化符合正常的家庭晨间活动规律。",
  "reasoning": [
    "1. **活动模式一致性分析**：连续三天（7月1日-3日）的日志显示，住户在清晨06:00-07:30期间有规律地起床并分散到各个房间（主卧、儿童房、客厅、餐厅）。这种跨天的行为模式高度一致，表明是常规的家庭作息，而非入侵者或异常情况。",
    "2. **厨房灶具使用逻辑正常**：7月1日06:35开启灶具，7月3日06:42开启灶具并在07:13关闭。虽然7月2日未记录到明显的灶具开启事件（可能未使用或日志筛选遗漏），但已记录的两次使用均伴随人员活动（如儿童房/客厅有人），且使用后及时关闭，未发现无人看管烹饪（unattended_cooking）的迹象。",
    "3. **门锁与传感器联动正常**：7月1日07:11和7月2日07:32出现的门锁操作及门磁状态变化，发生在住户已经起床并活动之后（此时多个房间 occupancy=1），符合住户出门上班或外出的正常行为，不存在非法入侵特征。",
    "4. **传感器数据合理性**：温度传感器读数随时间缓慢上升（从~24.5°C升至~25.2°C左右），符合室内环境温度随日照和人体活动逐渐升高的物理规律，无突变或停滞，排除传感器故障。"
  ],
  "key_evidence": [
    "连续三天清晨06:30-07:30期间，多个房间（living_room, master_bedroom, kids_room）的运动传感器依次触发，呈现典型的家庭成员陆续起床的活动轨迹。",
    "厨房灶具仅在有人活动的时段短暂开启，且随后关闭，无长时间无人值守情况。",
    "门锁解锁/上锁事件发生在住户已离开卧室区域后，符合离家逻辑。"
  ],
  "recommended_actions": [
    "无需采取紧急措施。",
    "建议继续保持当前的自动化规则监控，若未来出现深夜非正常时段的人员活动或门窗异常开启，再行介入分析。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "fire_risk",
  "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": [
    "触发时间位于清晨起床窗口且有轻微抖动，不是固定的可疑重复模式。"
  ],
  "recommended_actions": [

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。

    "3. 灯光控制符合习惯：10:07 客厅主灯开启（True），此时客厅虽无运动传感器触发（可能因刚进入尚未被捕捉或传感器延迟），但结合卧室有人活动的背景，可能是住户从卧室前往客厅短暂查看或经过，开灯行为合理。",

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

## 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",

    "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。

  "reasoning": [

    "2. 分析后续行为：在 08:02:00 再次出现开门（Contact=False）和解锁（LockState=2 -> 1）的动作，且此时玄关 occupancy 传感器在 08:00:36 曾短暂触发为 1，表明有人在家门口活动。结合早晨的时间点（07:40-08:02），这极有可能是住户离开家后返回取物、或家庭成员间的进出互动，属于正常的生活行为。",
    "3. 排除异常特征：整个过程中没有发现暴力破坏痕迹、非法入侵尝试（如多次错误密码）、或长时间未关锁等异常情况。所有设备状态变化均有合理的物理动作对应，且时间间隔符合人类行为节奏。"

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 3 天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",

    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",

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. **门锁与出入安全**：仅在8月3日07:29记录了一次手动开锁和关门事件，随后门锁关闭。这是典型的早晨离家行为。其他时间门窗传感器均处于闭合状态（隐含在正常温度波动中，且无开启报警），入户门无异常频繁开启或非法解锁尝试。",
    "3. **环境与安全设备**：厨房灯光在傍晚（12:12, 18:01, 18:54）及早晨（06:47）开启，符合烹饪或日常活动习惯。烟雾报警器、漏水传感器、一氧化碳报警器均未触发任何警报事件。温度传感器读数随昼夜自然变化，无剧烈跳变表明传感器工作正常。",
    "4. ** occupancy 逻辑一致性**：运动传感器在夜间（如00:00-05:00）显示无人（Occupancy=0），清晨有人活动时变为1，随后人离开房间又变为0。这种模式在三天内重复出现，逻辑自洽，排除了传感器卡死（stuck）或故障的可能性。"

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
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: ..."

    "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。

    "2. 室内活动轨迹合理：从 09:52 开始，客厅、玄关、厨房等区域陆续出现 occupancy 信号，且伴随温度传感器数据上报，表明老人在家中正常活动。各房间传感器状态变化（如卫生间 occupancy 归零）符合如厕或短暂离开的生活习惯。",
    "3. 无异常入侵迹象：虽然 14:05 门锁显示为锁定状态 (LockState=2) 且门磁为关闭 (False)，但这与之前 08:32 的上锁动作一致，且后续有室内人员活动（14:06 玄关灯亮，14:07 客厅有人），说明是老人自己在屋内反锁或确认门锁状态，而非外部入侵尝试。",
    "4. 环境参数稳定：各房间温度读数在合理范围内波动（约 23-25°C），无烟雾报警或漏水警报触发，排除火灾和水患风险。"
