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，所有设备日志符合正常的住户作息规律。",
  "reasoning": [
    "1. **作息规律性分析**：对比7月23日、24日和25日的活动摘要及详细日志，住户的起床时间（约06:30-06:45）和离开家时间（约07:26）高度一致。例如，两天早晨均在06:30左右卫生间有人活动，随后卧室/客厅有人，最后在07:26左右完成出门动作（门锁操作+门传感器关闭），显示出稳定的生活节奏。",
    "2. **离家状态确认**：在7月24日07:26之后，直到当天晚上23:06之前，living_room_occupancy（客厅 occupancy）持续为0，且无其他主要区域（如厨房、卧室）的活跃迹象，表明房屋确实处于无人状态，排除了非法入侵或设备误报的可能性。",
    "3. **设备行为逻辑自洽**：早晨的活动序列（卫生间灯亮->人进入->卧室灯亮->客厅有人->厨房灯短暂亮起后熄灭->出门）符合典型的“洗漱-穿衣-准备早餐/咖啡-出门”流程。特别是7月23日07:05厨房灯亮，07:31熄灭，与07:26出门的时间点虽有微小重叠（可能是在门口整理或最后检查），但整体逻辑通顺，非异常长时未关电器。",
    "4. **环境数据正常**：温度传感器读数随时间缓慢变化，符合室内热惯性特征，无突变或传感器卡死（stuck）的迹象。"
  ],
  "key_evidence": [
    "连续三天早晨06:30-07:30期间，卫生间、卧室、客厅的Occupancy和Light事件呈现一致的先后顺序，符合正常起床流程。",
    "7月24日07:26:14至07:26:17，入户门锁执行了Manual Unlock -> Door Open (Contact=False) -> Manual Lock 的操作序列，明确标识住户已离家并锁门。",
    "7月24日07:30至23:06期间，living_room_occupancy保持为0，确认房屋长时间无人，排除入侵风险。"
  ],
  "recommended_actions": [
    "无需采取任何安全措施，系统运行正常。",
    "建议继续保持当前的自动化规则（如离家自动关灯/安防布防），以维持良好的居住体验。"
  ]
}
```

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "fire_risk",

  "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。"

    "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。"

## 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",

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. 人员活动轨迹合理：入口运动传感器在 12:29-13:50 期间多次触发，且伴随客厅、主卧等区域的人员存在信号（Occupancy=1）和环境温度变化，表明住户在家中正常活动。夜间（00:00）客厅无人，符合作息规律。",
    "3. 传感器数据一致性高：各房间温度传感器读数在 24.6°C - 25.0°C 之间波动，数值变化平缓且符合物理规律（如空调运行或自然散热导致的微小温差），未发现传感器卡死（数值不变）或漂移（数值突变）的迹象。",

    "推理步骤 2: 结合 Matter 协议标准及常识判断，家庭室内环境温度通常在 -10°C 到 50°C (即 263K-323K) 范围内。日志中的 2490+ 数值明显超出物理极限，属于无效数据。",
    "推理步骤 3: 虽然入户门锁和接触传感器在 07:24 和 14:05 有正常的开关操作记录，且 occupancy 传感器也有合理的人员进出逻辑，但持续性的全房间温度读数错误排除了真实高温环境的可能性，确认为传感器硬件故障或校准失效导致的 sensor_malfunction。"

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：

  "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",

    "4. 无异常入侵迹象：入户门锁（entrance_door_lock）未在日志中触发开锁或报警事件，且所有运动传感器均在室内区域活动，未发现非授权进入或长时间静止不动（跌倒/昏迷）的迹象。"

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。

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。

  "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。

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": [
    "1. 人员活动轨迹符合常理：日志显示老人在09:31-09:54期间在厨房、卧室和玄关有短暂活动（Occupancy=1），随后在09:37和10:07卫生间传感器显示无人（Occupancy=0），这符合老人起床后洗漱、去厨房或卧室活动的日常行为模式。",
    "2. 关键设备状态无异常冲突：客厅灯在08:39和10:07开启，与人员在场时间吻合；窗户传感器在10:05-10:06显示关闭（False），表明门窗处于安全闭合状态，未发现非法入侵迹象。",

    "bathroom_occupancy 在 09:37 和 10:07 变为 0，符合如厕/洗漱后离开的行为逻辑",
    "living_room_window_contact 和 bedroom_window_contact 均为 False (Closed)，门窗安全",

  ],
